The user can analyze the multiple key signals through the key analysis unit in the video editing device to obtain the time stamp corresponding to the key key information, and the video processing unit extracts the edited video fragments corresponding to the time stamp from the video to be edited, and finally generates a highlight video The edited video can save a lot of labor cost and time cost, and save the user the labor of post-production video.

Please refer to FIG. 1 , the present disclosure provides a video editing device 300 connected to the video source device 100 and the control device 200 . Wherein, the video source device 100 can be the host of the game machine, and the control device 200 can be the joystick or keyboard of the game machine. When the user manipulates the buttons on the control device 200 to execute video games in the video source device 100, the video editing device 300 will capture and store the key signal S1 synchronously, and at the same time the video editing device 300 will obtain and automatically record the game from the video source device 100 process picture to generate a movie (or video editing device 300 receives the video of the game process picture from video source device 100), and then, video editing device 300 can edit the video according to the type, number of occurrences and occurrence frequency of each key signal S1. Continuous highlights of the gameplay. Therefore, the user does not need to manually record the game screen during the game, and does not need to manually edit the game process after the game is over. By implementing the video editing device 300, a large amount of labor costs and time costs can be saved. The technical content of this disclosure will be described in detail later.

In one embodiment, the video editing device 300 of the present disclosure includes a key analysis unit 310 and a video processing unit 320 . The key analysis unit 310 is coupled to the video processing unit 320 and the control device 200 , and the video processing unit 320 is coupled to the video source device 100 .

During the game, when the user presses a button of the control device 200, the control device 200 generates a plurality of button signals S1 corresponding to the pressed buttons. At this time, the key analysis unit 310 can receive a plurality of key signals S1 from the control device 200 (step S100 shown in FIG. 2 ), wherein each key signal S1 includes color, etc.) to execute the button information of the action.

Please refer to FIG. 1 and FIG. 2 at the same time, the key analysis unit 310 obtains at least one key key information from the plurality of key signals S1 (step S200 ). Specifically, after obtaining the key signal S1 (step S100), the key analysis unit 310 will calculate the key information of the key signal S1 to select one or more key information from the key information of the key signal S1, and The selected button information is the key button information (step S200 ). Wherein, each key signal S1 also has a time stamp T1 used to indicate the generation time of the key signal S1. When any game process screen is played, the user can manipulate the control device 200 to generate the key signal S1 in order to control the controlled object in the game process screen. In other words, the generation of the key signal S1 is synchronized with the playback of the game process screen where the controlled object to be controlled by the key signal S1 is located. Since each key signal S1 is generated to control the execution of the controlled object on a certain game process screen, the time stamp T1 of each key signal S1 will be the same as the time stamp of the game process screen where the controlled object is located (that is, the game playback time of the process picture). In the video, the game process screen whose time stamp is the same as the time stamp T1 of the key signal S1 to which the key key information belongs is the highlight segment picture that the user wants to edit.

When the key analysis unit 310 obtains each key key information from the multiple key signal S1 (step S200), the key analysis unit 310 will obtain the corresponding time stamp T1 according to the key key information (step S300), and send the time stamp T1 to the video processing Unit 320. In other words, the key analysis unit 310 obtains the time stamp T1 of the key signal S1 to which the key key information belongs (step S300 ), and sends the obtained time stamp T1 to the video processing unit 320 .

Next, the video processing unit 320 receives the video F1 to be edited from the video source device 100 (step S400 ). In one embodiment, the video to be edited F1 is a video obtained by the video source device 100 currently recording the game process when the user executes the video game of the video source device 100 . In another embodiment, the video F1 to be edited is generated by the video editing device 300 receiving and storing it from the video source device 100 in real time during the game.

The video processing unit 320 receives the time stamp T1 from the key analysis unit 310 , and extracts at least one clip corresponding to the time stamp T1 from the video F1 to be edited (step S500 ). That is to say, the video processing unit 320 corresponds the time stamp T1 corresponding to each key key information to the video time information recorded in the video to be edited F1, and the video segment corresponding to the time stamp T1 in the video to be edited F1 (i.e. its (consisting of one or more game process screens in continuous time) is captured as at least one video clip, and the video time information recorded in the video clip corresponds to the time stamp T1. Here, the key key information is a part of the key information selected from the key information of all the key signal S1 received by the key analysis unit 310, so the video processing unit 320 can use the time stamp of the key signal S1 to which the key key information belongs. T1 clips a part of the game process screen whose time stamp corresponds to the time stamp T1 from all the game process screens of the movie F1 to be edited as a clip of the video clip. Each movie clip segment includes game process pictures corresponding to one or more time stamps T1 that are continuous in time. In some embodiments, the playing time of the game process picture constituting the edited video segment in the video to be edited F1 is the same as the generation time of the key signal S1 to which all the key key information belongs, that is, the game process picture of the edited video segment is in the video to be edited. The time stamp in F1 is the same as the time stamp T1 of the key signal S1 to which all key key information belongs.

Then, the video processing unit 320 integrates and connects the captured at least one edited video segment to generate and output the edited video F2 (step S600 ). In one embodiment, the video processing unit 320 connects the start end of each video clip to the end of the previous video clip, and connects the end of each video clip to the start of the next video clip to synthesize the clip After the film F2. Wherein, since each key signal S1 is used to control the execution action of a controlled object in a certain game process screen in the video to be edited F1, the total time length of the video to be edited F1 is greater than or equal to the total time length of the key signal S1. The edited video F2 is an edited highlight video, that is, the game process screens contained in it correspond to the selected button information (ie key button information) in time, so the total time length of the edited video F2 is less than The total time length of the video F1 to be edited is less than the total time length of the key signal S1 received by the key analysis unit 310 .

Based on this, the user does not need to manually record the game screen while playing the game, and does not need to manually edit the game process after the game is over. The user analyzes the multiple key signal S1 through the key analysis unit 310 to obtain the time stamp T1 corresponding to the key key information, and the video processing unit 320 extracts the video clip corresponding to the time stamp T1 from the video F1 to be edited, and finally generates a video clip The edited video F2 can save a lot of labor and time costs, and save the user the inconvenience and labor of manual video production.

In some embodiments, please refer to FIG. 3 , the key information of each key signal S10 - S19 corresponds to the type of key that is manipulated to generate the key signal S1 by manipulating the control device 200 . Here, the types of keys of the control device 200 include arrows (including four directions of up, down, left, and right), triangles, circles, crosses, squares, or any combination thereof. For example, when the user presses the up key button in the control device 200, the control device 200 generates a key signal S10 including the up key information, that is, the key information of the key signal S10 is the up key information; For the up button and the triangle button in the control device 200, the control device 200 generates a key signal S11 including the information of the up button and the information of the triangle button. Triangle button information. The rest of the key types and their corresponding key information can be deduced in the same way, and will not be repeated here.

In order to enable the key analysis unit 310 to achieve better efficiency during operation, in some embodiments, the key analysis unit 310 can allocate the key signal S1 according to the time sequence generated to generate multiple signal time segments (step S210) . Wherein, the number of signal time segments generated by the key analysis unit 310 can be adjusted, and the number of key signals S1 assigned to each signal time segment can also be adjusted.

In some embodiments, the key analysis unit 310 divides the plurality of key signals S1 generated by the key within a period of time into plural groups according to the generation time. Therefore, each key signal group is a signal time segment.

In some embodiments, at least one of the plurality of key signals S10 - S19 generated by the control device 200 is repeatedly allocated to two adjacent signal time segments within a period of time. For example, referring to FIG. 3 , for adjacent signal time segments, the latest key signal S13/S16 is generated in the previous signal time segment C1/C2 and the earliest key signal is generated in the subsequent signal time segment C2/C3. The key signal S13/S16 is the same key signal S13/S16. The present invention is not limited by this embodiment, and all adjustments made according to requirements are within the scope of this case.

For example, referring to FIG. 3 , taking 10 key signals S10 - S19 generated continuously as an example, the key signals S10 - S19 are arranged in order of generation, the key signal S10 is generated first, and the key signal S19 is generated last. The key analysis unit 310 correspondingly distributes the key signals S10-S19 according to the generated time sequence to generate three signal time segments C1-C3. Wherein, according to the chronological sequence of the key signals S10-S19, the signal time segment C1 may include the key signals S10-S13, the signal time segment C2 may include the key signals S13-S16, and the signal time segment C3 may include the key signals S16-S19. In other words, the key signal S13 is repeatedly allocated to the signal time segments C1 and C2, and is the last one in the signal time segment C1, and the first one in the signal time segment C2. The button signal S16 is repeatedly allocated to the last signal time segment C2 and the first signal time segment C3 is repeatedly allocated. Here, although 10 key signals S10-S19 are taken as an example, the number of key signals S1 analyzed by the key analysis unit 310 is not limited thereto. In other words, the number of key signals S1 analyzed by the key analysis unit 310 is adjustable. of.

In some other embodiments, as shown in FIG. 4 , any one of the plurality of key signals S10 - S19 generated by the keys of the control device 200 within a period of time is only allocated to one signal time segment. That is to say, the key signals S10-S19 are not repeatedly assigned to different signal time segments.

For example, referring to FIG. 4 , taking 10 continuously generated key signals S10 - S19 as an example, the key analysis unit 310 allocates the key signals S10 - S19 according to the generated time sequence to generate 3 signal time segments C1 - C3 . According to the chronological sequence of the key signals S10-S19, the signal time segment C1 can include the key signals S10-S13, the signal time segment C2 can include the key signals S14-S17, and the signal time segment C3 can include the key signals S18-S19.

In some embodiments, please refer to FIG. 5 and FIG. 6 , taking seven signal time segments C1-C7 as an example to illustrate how to obtain key signal segments in this case, so as to further edit exciting game segments. In step S200, after the key analysis unit 310 receives the complex key signals S10-S31, the key analysis unit 310 assigns the complex key signals S10-S31 according to the generated time stamp T1 to generate the complex signal time segments C1-C7 (step S210). For example, taking the complex key signal S1 as the complex key signal S10-S31 shown in FIG. Segment C2, signal time segment C3 including key signals S16-S19, signal time segment C4 including key signals S19-S22, signal time segment C5 including key signals S22-S25, signal time segment C6 including key signals S25-S28 , and a signal time segment C7 including key signals S28-S31.

The key analysis unit 310 calculates the multiple key signal quantities E1-E7 corresponding to the signal time segments C1-C7 according to the complex key signals S10-S31 (step S220). Next, the key analysis unit 310 compares each key signal amount E1-E7 with a preset message amount V1 (step S230), so as to determine each key signal amount E1-E7 corresponding to each signal time segment C1-C7 Whether it is greater than the default message volume V1 (step S240).

Here, when any one of the key signal amounts E1-E7 is greater than the predetermined value V1 of the message amount (the judgment result is “Yes”), the key analysis unit 310 obtains the key signal whose amount is greater than the predetermined value V1 of the message amount. One or more signal time segments, and the obtained signal time segment is used as the first key signal segment (step S250). When any one of the key signal amounts E1-E7 is less than or equal to the message amount preset value V1 (judgment result is "No"), the key analysis unit 310 discards (does not obtain) the key signal amount less than or equal to the message The signal time segment of the preset value V1, that is, the signal time segment whose key signal volume is less than or equal to the preset value V1 of the message volume is not used as the first key signal segment.

In some embodiments, the key analysis unit 310 acquires the key information of the plurality of key signals in the first key signal section as the aforementioned at least one key key information (step S270 ). In other words, the key button information is the button information whose button signal volume is greater than the preset message volume value V1 in all signal time segments.

For example, as shown in FIG. 6 , the key analysis unit 310 correspondingly distributes the multiple key signals S1 to generate multiple signal time segments C1-C7, and the key analysis unit 310 calculates the key signal S10-S13 according to the signal time segment C1. The key signal amount E1 is the key signal amount E1 calculated by the key analysis unit 310 according to the key information in the key signals S10 - S13 . Similarly, the key analysis unit 310 can also calculate the key signal quantities E2-E7 according to the key signals S13-S31 in the signal time segments C2-C7. The key analysis unit 310 compares the key signal quantities E1, E2 with the preset message volume value V1, and can know that the key signal quantities E1, E2 are smaller than the message volume preset value V1. The key analysis unit 310 compares the key signal volume E3 with the preset message volume value V1, and can learn that the key signal volume E3 is greater than the message volume preset value V1. The key analysis unit 310 completes the comparison between the key signal quantities E4-E7 and the message quantity preset value V1 by analogy as mentioned above. After the comparison, the key analysis unit 310 obtains the signal time segments C3-C5 whose key signal volume is greater than the preset value V1, and takes the signal time segments C3-C5 as the first key signal segment. The key analysis unit 310 uses the key information corresponding to the plurality of key signals S16-S25 in the first key signal segment as the aforementioned key key information.

In some embodiments of step S220, the key analysis unit 310 may calculate the key signal quantities E1-E7 of each signal time segment C1-C7 according to the weight ratio of various key information. In some embodiments, the key analysis unit 310 can use an entropy (Entropy) algorithm to obtain the key signal quantities E1-E7 of each signal time segment C1-C7. The button analysis unit 310 calculates the self-information value of the button information of each button type according to the button information of all the button signals S1 corresponding to the movie F1 to be edited, and uses the self-information value of the button information of all button types to calculate the overall entropy value. The key analysis unit 310 averages the key information values of the key signal S1 in each signal time segment C1-C7 according to the body information value of the key information of each key type to calculate the average information value of each signal time segment C1-C7 . Finally, the key analysis unit 310 divides the average information value corresponding to each signal time segment C1-C7 by the overall entropy value to obtain the key signal amount E1-E7 of each signal time segment C1-C7. Here, the key signal quantities E1-E7 of each signal time segment C1-C7 can represent the proportion of the key signal S1 in the signal time segment C1-C7 in the whole (that is, all the key signal S1 corresponding to the video F1 to be edited) . Wherein, the above-mentioned entropy algorithm is only illustrated as an example, and the present invention is not limited thereto; An algorithm similar to the entropy algorithm concept is obtained.

In some embodiments, the body information value of the key information of each key type can be calculated by performing mathematical operations (such as addition, subtraction, multiplication, division, logarithm, square root, etc.) Mathematical operations) are obtained. In this way, the obtained body information value of the button information of the button type is equivalent to the weight ratio of the button information of this button type in the whole. The overall entropy value is the sum of the product of the ontology information value of each key type and its occurrence probability.

In some other embodiments, after obtaining the first key signal segment, the key analysis unit 310 can be based on the remaining signal time segments (such as C1, C2, C6, C7) other than the first key signal segment (such as C3-C5). ) and the signal time segments (eg C3, C5) adjacent to the remaining signal time segments (eg C1, C2, C6, C7) in the first key signal segment (eg D1, D2, D6, D7) to determine Screen the remaining signal time segments to confirm whether they are key signal time segments, and use the filtered key signal time segments as the second key signal segment (step S260 ).

Then, the key analysis unit 310 acquires the key information of the plurality of key signals in the first key signal section and the second key signal section as the aforementioned at least one key key information (step S270 ). In other words, the key key information not only includes the key information of the key signals contained in at least one signal time segment whose key signal volume is greater than the preset value V1 in all the signal time segments, but also includes the key signal volume less than the preset value of the message volume. The key information of the key signal contained in at least one signal time segment similar to the first key signal segment in the signal time segment with value V1.

In some embodiments, referring to FIG. 7 , the key analysis unit 310 acquires the signal time segment at the initial position in the first key signal segment as the reference segment (step S261 ), and uses the signal time segment preceding the reference segment as the candidate segment. (step S262 ), and calculate the degree of correlation between the reference segment and the candidate segment, that is, the degree of similarity between the reference segment and the candidate segment (step S263 ). In some embodiments, the keystroke analysis unit 310 may use a Dynamic Time Warping (DTW) algorithm to calculate the first degree of similarity between the reference segment and the candidate segment. Here, the smaller the scores of the reference segment and the candidate segment obtained after the DTW algorithm are, the higher the similarity between the reference segment and the candidate segment is. However, the present invention is not limited thereto. In some embodiments, the similarity between the reference segment and the candidate segment can be determined through other algorithms.

Then, the key analysis unit 310 compares the similarity degree with the similarity preset value V2 (step S264 ), so as to determine whether the similarity degree is smaller than the similarity preset value V2 (step S265 ).

Here, when the similarity degree is less than the similarity preset value V2 (the judgment result is "Yes"), the key analysis unit 310 adds the candidate segment to the qualified time segment (step S266), and confirms whether there is any signal time before the current candidate segment Segment (step S267a); if there is, take the signal time segment before the candidate segment as a new candidate segment (step S267b), and return to execute step S263 to perform this new candidate segment and the aforementioned reference segment (i.e. the first key signal The similarity of the signal time segment at the initial position in the segment) is judged; otherwise, if there is no, the accumulated qualified time segment is used as the second key signal segment (step S269). When the degree of similarity is greater than or equal to the similarity preset value V2 (judgment result is "No"), the key analysis unit 310 discards (does not acquire) the current candidate segment (step S268) and uses the accumulated qualified time segment as the second key signal segment (step S269).

In some embodiments, referring to FIG. 8 , the key analysis unit 310 obtains the signal time segment at the last position in the first key signal segment as a reference segment (step S261'), and obtains the next signal time segment of the reference segment as a candidate segment (step S262'), and calculate the degree of correlation between the reference segment and the candidate segment, that is, the degree of similarity between the reference segment and the candidate segment (step S263'). Then, the key analysis unit 310 compares the similarity degree with the similarity preset value V2 (step S264'), so as to determine whether the similarity degree is smaller than the similarity preset value V2 (step S265').

Here, when the similarity degree is less than the similarity preset value V2 (the judgment result is "Yes"), the key analysis unit 310 adds the candidate segment to the qualified time segment (step S266'), and confirms whether there is any signal after the current candidate segment time segment (step S267a'); if there is, then take the signal time segment after the candidate segment as a new candidate segment (step S267b'), and return to execute S263' to perform the new candidate segment and the aforementioned reference segment (that is, the first the signal time segment at the last position in a key signal segment); on the contrary, if there is no similarity, the accumulated qualified time segment is used as the second key signal segment (step S269'). When the degree of similarity is greater than or equal to the similarity preset value V2 (judgment result is "No"), the key analysis unit 310 abandons (does not obtain) the current candidate segment (step S268') and uses the accumulated qualified time segment as the second Key signal section (step S269').

In some embodiments, the key analysis unit 310 may also use the signal time segment at the initial position in the first key signal segment to filter the signal time segment before the first key signal segment, and then continue to use the first key The signal time segment at the last position in the signal segment filters the signal time segment after the first key signal segment to find the second key signal segment, as shown in FIG. 9 . In some other embodiments, the key analysis unit 310 may also use the signal time segment at the last position in the first key signal segment to filter the signal time segment after the first key signal segment, and then continue to use the first key The signal time segment at the initial position in the signal segment filters the signal time segment before the first key signal segment to find the second key signal segment, as shown in FIG. 10 .

For example, suppose the first key signal segment among the seven signal time segments C1-C7 shown in FIG. 6 is the signal time segment C3-C5. The key analysis unit 310 first obtains the signal time segment C3 at the start position in the first key signal segment as a reference segment, and obtains a signal time segment C2 preceding the signal time segment C3 as a candidate segment. Then, the key analysis unit 310 uses a dynamic time correction algorithm to calculate the signal time according to the multiple key signals S13-S16 in the signal time segment C2 (ie, the candidate segment) and the key signals S16-S19 in the signal time segment C3 (ie, the reference segment). The similarity D2 between the segment C2 and the signal time segment C3 is compared with the similarity default value V2.

When the similarity degree D2 is less than the similar preset value V2, the key analysis unit 310 adds the current candidate segment (ie, the signal time segment C2) to the qualified time segment, and then obtains the previous signal time of the candidate segment (ie, the signal time segment C2) Segment C1 serves as a new candidate segment. Then, the key analysis unit 310 uses a dynamic time correction algorithm to calculate the The similarity D1 between the signal time segment C1 and the signal time segment C3 is compared with the similarity default value V2. Here, when the comparison result shows that the similarity D1 between the signal time segment C1 and the signal time segment C3 is greater than or equal to the similarity preset value V2, the key analysis unit 310 discards the signal time segment C1.

Next, the key analysis unit 310 obtains the last signal time segment C5 in the first key signal segment as the reference segment, and obtains the next signal time segment C6 of the signal time segment C5 (ie, the reference segment) as the candidate segment. Then, the key analysis unit 310 uses a dynamic time correction algorithm to calculate the signal time according to the multiple key signals S25-S28 in the signal time segment C6 (ie, the candidate segment) and the key signals S22-S25 in the signal time segment C5 (ie, the reference segment). The similarity D6 between the segment C6 and the signal time segment C5 is compared with the calculated similarity D6 with the similarity preset value V2. And, when the comparison result is that the similarity degree D6 between the signal time segment C5 and the signal time segment C6 is greater than or equal to the similarity preset value V2, the key analysis unit 310 discards the signal time segment C6, and accumulates qualified time segments ( That is, the signal time segment C2) is used as the second key signal segment.

In some embodiments of step S270, after obtaining the first key signal segment and the second key signal segment, the key analysis unit 310 obtains the multiple key signals in the first key signal segment and the second key signal segment The button information is used as the aforementioned at least one key button information.

In some embodiments, the message volume default value V1 and the similar default value V2 are adjustable. When the predetermined value V1 of the message volume is larger, the condition setting of the key analysis unit 310 is more stringent when comparing the signal volume of the keystroke with the preset value V1 of the message volume. Therefore, compared with the signal time segments obtained when the preset value of message volume V1 is small, the number of signal time segments obtained when the preset value of message volume V1 is larger is smaller, that is, the number of signal time segments included in the first key signal segment Signal time segments are less. Under the similar condition that the preset value V2 is fixed, the total time length of the edited video F2 generated and output by the video processing unit 320 is relatively short.

On the contrary, when the preset message volume value V1 is small, the condition setting of the key analysis unit 310 is relatively simple when comparing the key signal volume with the preset message volume value V1. Moreover, under the condition that the preset value V2 is fixed, the preset value V1 of information volume is small, and the total time length of the edited video F2 generated and output by the video processing unit 320 is relatively long.

And when the similar preset value V2 is larger, the pass condition setting is simpler when the key analysis unit 310 screens the remaining signal time segments outside the first key signal segment. Therefore, compared to the judging result when the similar default value V2 is small, the larger the similar default value V2 is, the easier it is for the key information of the plurality of key signals corresponding to the second key signal segment or the remaining signal time segment to become the key key information. Under the condition that the preset value V1 of the amount of information is fixed, and the similar preset value V2 is larger, the total time length of the edited video F2 generated and output by the video processing unit 320 is relatively longer.

On the contrary, the smaller the similar preset value V2 is, the stricter the pass condition setting is for the key analysis unit 310 when screening the remaining signal time segments other than the first key signal segment. Moreover, under the condition that the preset value V1 of the amount of information is fixed, and the similar preset value V2 is small, the total time length of the edited video F2 generated and output by the video processing unit 320 is relatively short.

To sum up, under the application of the video editing device according to any embodiment or the video editing method of any embodiment, the user does not need to manually record the game screen at the same time during the game, and does not need to manually edit it after the game is over. game process.
