Fig. 1 is a schematic flow chart of a video recording method according to an embodiment of the present application, as shown in fig. 1, including:

step 110, receiving a first input of a first video, wherein the first video comprises N frames of preview frames and M frames of buffer frames;

the first video described in the embodiments of the present application may specifically be a video recorded by a user in advance, where the user is recording a video, and in an embodiment, the first video may also be a part of video content in a video that is continuously shot.

The first video may be a video stored locally at the terminal device or may be a video stored at the cloud server.

In the video recording process, the user is often helped to know the recorded video content along with the video preview process, the video preview has higher requirement on real-time performance, all video frames collected in the video recording process cannot be previewed, only part of video frames in the video frames can be previewed and displayed, the video frames used for the video preview are preview frames, and the cache frames can be video frames cached in the preview process, namely, video frames which are not subjected to video preview in the recorded video frames are cache frames.

In the embodiment of the present application, the N frame preview frames are video frames for performing video preview in the recorded first video, and the M frame buffer frames are video frames for not performing video preview in the recorded first video, which can be understood that the buffer frames may be video frames recorded between each preview frame.

The terminal device receives the first input of the first video, and the terminal device may be a device with a video recording function, specifically may be a device such as a mobile phone, a camera, a tablet computer, etc., and the type of the terminal device is not specifically limited in the embodiment of the present application.

In an alternative embodiment, the first input may also be an operation of using, as the first video, a part of the video content that has completed recording during the video recording process, and generating a plurality of sets of jitter intensity adjustment coefficients based on the first video.

In another alternative embodiment, the first input may be an operation for importing a first video, generating a plurality of sets of jitter intensity adjustment coefficients based on the first video, and the first input may be the first operation.

The video recording preview interface may include a video import identifier, where the first operation includes, but is not limited to, selecting a video file corresponding to the first video and confirming an import operation after the user clicks the video import identifier by a touch device such as a finger or a stylus; or the first input may also be a voice command input by the user, or a specific gesture input by the user, or other feasibility inputs, which may be specifically determined according to the actual use requirement, and the embodiment of the present invention is not limited. The specific gesture in the embodiment of the application may be any one of a single-click gesture, a sliding gesture, a dragging gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-press gesture and a double-click gesture; the click input in the embodiment of the application may be a single click input, a double click input, or any number of click inputs.

Step 120, in response to the first input, displaying P jitter intensity adjustment identifiers on a video recording preview interface; each jitter intensity adjustment identifier points to a group of jitter intensity adjustment coefficients, the jitter intensity adjustment coefficients are used for compensating video jitter generated in the video recording process, the jitter intensity adjustment coefficients are generated according to a video frame data set, each video frame data set comprises N frames of preview frames and a buffer frame set, the number of buffer frames in each buffer frame set is different, and M, N and P are positive integers.

The terminal device may further generate a plurality of groups of video frame data sets according to the N preview frames and the different number of buffered frames in the first video after importing the first video in response to the first input.

In some embodiments, the number of buffered frames in the video frame data set may be set by the user, or may be generated according to a certain preset scheme, for example, each set of video frame data sets introduces 3 buffered frames more than the previous frame data set, and theoretically, the larger the number of buffered frames applied in the video frame data sets, the smaller the generated jitter intensity adjustment coefficient, and the higher the anti-jitter intensity.

For example, the first video includes 5 frames of preview frames and 50 frames of buffer frames, three sets of video frame data sets are generated, and the first set of video frame data sets may include 5 frames of preview frames and 3 frames of buffer frames adjacent to each frame of preview frames, namely 15 frames of buffer frames; the second group of video frame data groups comprises 5 frames of preview frames and 5 frames of buffer frames adjacent to each frame of preview frames, namely 25 frames of buffer frames; the third set of video frame data includes 5 frames of preview frames and 7 frames of buffer frames adjacent to each frame of preview frames, i.e., 35 frames of buffer frames.

In this embodiment of the present application, after generating multiple sets of video frame data sets according to N frame preview frames and different numbers of buffer frames of the first video, a corresponding jitter intensity adjustment coefficient may be further generated according to each set of video frame data sets, for example, if the first video generates 5 sets of video frame data sets, the 5 sets of jitter intensity adjustment coefficients may be generated.

In an alternative embodiment, the shake strength adjustment coefficient is a coefficient for compensating video shake occurring in the video recording process, the shake strength adjustment coefficient may be an anti-shake coefficient matrix, where the matrix may include X, Y, pitch, yaw and roll anti-shake adjustment coefficients, and shake in X, Y, pitch, yaw and roll directions may be compensated by the anti-shake strength adjustment coefficient during the video recording process, so that stability of video shooting is effectively ensured. In an alternative embodiment, after generating multiple sets of jitter intensity adjustment coefficients, the corresponding jitter intensity adjustment coefficients may be generated according to the number of buffered frames corresponding to each jitter intensity adjustment coefficient, for example, the jitter intensity adjustment coefficient obtained without using buffered frames is set to 0, the jitter intensity coefficient obtained using 15 buffered frames is set to 1, the jitter intensity coefficient obtained using 30 buffered frames is set to 2, so as to obtain the corresponding jitter position information.

In an optional embodiment, after generating a plurality of sets of jitter intensity adjustment coefficients, sorting is performed according to the adjustment values of the adjustment coefficients, so as to generate corresponding sorting information.

In an alternative embodiment, the P jitter intensity adjustment identifiers in the video recording preview interface may be displayed in a bar-shaped slidable page, and the user may select different jitter intensity adjustment identifiers by sliding the page.

In an alternative embodiment, P jitter intensity adjustment identifiers in the video recording preview interface may be displayed in a scattered manner, and the user may click on or long press the jitter intensity adjustment identifier that he wishes to select to set the corresponding jitter intensity adjustment coefficient.

In the embodiment of the application, in the video recording process, a video recording preview interface can be displayed in a display screen of the terminal device, and a user can view preview frames of recorded video through the video recording preview interface, so that shot video content is effectively known, and a shaking intensity adjustment mark for adjusting video recording parameters can be displayed in the video recording preview interface, so that the user can conveniently adjust in the video recording process.

Because the users have difference in the shake intensity feeling, the users can adjust the shake intensity through the shake intensity adjusting mark in the video recording process, and the shake intensity adjusting coefficient which is most suitable for the eyes of the users is selected to record the video, so that the final video recording output is obtained.

In an alternative embodiment, after setting the jitter intensity adjustment factor, the user defaults to use the jitter intensity adjustment factor set by the user to perform anti-jitter processing when recording the video again through the mobile terminal.

In the embodiment of the application, the first video shot by the user in advance is imported, then a plurality of groups of video frame data sets are constructed through N frames of preview frames and different numbers of buffer frames in the first video, a plurality of groups of jitter intensity adjustment coefficients which are more fit with the shooting habit of the user are generated according to the plurality of groups of video frame data sets, and corresponding jitter intensity adjustment identifiers are further displayed on a video recording interface, so that the user can select the jitter intensity adjustment coefficients which can be adapted according to the requirements during video recording, and the stability of recorded video pictures is effectively ensured.

Optionally, the method for generating the jitter intensity adjustment coefficient specifically includes:

Acquiring first motion offsets of the buffer frames and the preview frames in the video frame data set, and determining first difference values of the first motion offsets and target motion offsets, wherein the target motion offsets are minimum values in the first motion offsets;

and determining the jitter intensity adjustment coefficient according to the total frame number of the buffer frame and the preview frame in the video frame data group and the absolute value of each first difference value.

In this embodiment of the present application, the first motion offset is a motion estimation offset of a recording buffer frame or a preview frame relative to a first frame video frame recorded by a video, a minimum offset of the first motion offset of each buffer frame and the first motion offset of each preview frame of each video frame data set is selected, and the minimum offset is taken as a target motion offset, and it can be understood that, because there is a difference between preview frames included in each video frame data set, the minimum offset of each video frame data set may be different.

In one embodiment, a motion estimation curve of each video frame data set is constructed according to the first motion offset of each buffer frame and the first motion offset of each preview frame in one video frame data set, and the minimum value of the motion estimation curve is used as the corresponding target motion offset of the data frame set.

In this embodiment, the first motion offset P of each buffer frame and preview frame may be specifically _i For a motion offset P from the target _min The difference is obtained to obtain a plurality of first difference values (P _i -P _min )。

In one embodiment, the total frame number of the buffer frame and the preview frame in the video frame data set refers to a sum of the buffer frame number and the preview frame number in one video frame data set.

In one embodiment, the absolute values of the first differences in a video data may be summed to obtain a summed value, and then the summed value is divided by the total frame number to obtain the calculated jitter intensity adjustment coefficient for the video frame data set, which may specifically be:

wherein frame is the total frame number of the video frame data set, which can be specifically the sum of the frame numbers of the preview frame and the buffer frame in the video frame data set, P _i For the first motion offset, P _min For the target motion offset, i represents the i-th frame of the video recording for the video frame.

In the embodiment of the present application, different preview frames are included in different video frame data sets, so different jitter intensity adjustment coefficients can be obtained in the above manner.

In one embodiment, since the terminal device needs to be anti-shake in X, Y, pitch, yaw and roll directions, when the first motion offset is acquired, the motion offsets in X, Y, pitch, yaw and roll directions are correspondingly acquired, and then the obtained shake intensity adjustment coefficient is a matrix K, including shake intensity adjustment values in X, Y, pitch, yaw and roll directions, which are specifically formed as follows:

K＝(k _x ,k _y ,k _pitch ,k _yaw ,k _roll ) ^T

In this embodiment of the present application, the jitter intensity adjustment coefficient is effectively calculated by the total frame number of the buffered frame and the preview frame in the video frame data set, and the first difference value between the first motion offset and the target motion offset of the buffered frame and each preview frame, and a plurality of jitter intensity coefficients may be calculated by different numbers of buffered frames in each video frame data set, so that more choices may be provided to the user in the video recording process.

Optionally, in response to the first input, after displaying the P jitter intensity adjustment identifiers on the video recording preview interface, the method further includes:

receiving a second input of a target jitter intensity adjustment identifier in the P jitter intensity adjustment identifiers;

and responding to the second input, and recording the video according to a first jitter intensity adjustment coefficient corresponding to the target jitter intensity adjustment identifier, wherein the first jitter intensity adjustment coefficient is used for performing jitter compensation on the recorded video in the video recording process.

In one embodiment, the terminal device receives a second input of the target jitter intensity adjustment identifier from the P jitter intensity adjustment identifiers, where the second input is used to determine the target jitter intensity adjustment identifier for selection, and the second input may be a click input, a long press input, a sliding input, a voice command input or other input capable of implementing a response function, which is not limited in this embodiment.

The terminal device, in response to the second input of the user, records video according to the first jitter intensity adjustment coefficient corresponding to the target jitter intensity adjustment identifier, and it can be understood that, because in the embodiment of the application, the preview frame has stronger real-time performance, the first jitter intensity adjustment coefficient is not an adjustment coefficient for adjusting the preview frame alone, but performs jitter compensation on all video frames recorded and saved.

After the user finishes setting, the first jitter intensity adjustment coefficient is used as a default parameter of video recording of the terminal equipment, so that the user can be prevented from additionally setting each time when the video is recorded, and the steps of user operation are effectively reduced.

In an alternative embodiment, fig. 2 is one of display schematic diagrams provided in the embodiment of the present application, as shown in fig. 2, including: the anti-shake intensity setting identifier 211 may be displayed in the video recording preview interface 21, after the user clicks the anti-shake intensity setting identifier 211, the terminal device responds to the input to display the video import interface 22, and after the user imports the first video in the video import interface 22, P shake intensity adjustment identifiers 212 are displayed in the video recording preview interface 21.

In the embodiment of the application, the user can continuously switch the target jitter intensity adjustment identifiers among the P jitter intensity adjustment identifiers, so that the jitter intensity adjustment coefficient suitable for the user is effectively selected, the stability of final video recording is effectively ensured, and the quality of video recording is ensured.

Optionally, after the step of recording the video according to the first jitter intensity adjustment coefficient corresponding to the target jitter intensity adjustment identifier, the method further includes:

receiving a third input, wherein the third input is used for amplifying a target shooting area in the video recording preview interface according to a target amplification factor;

and responding to the third input, and controlling the first center point of the video recording preview interface and the second center point of the target shooting area in the recorded video picture to be close to each other in the process of amplifying the target shooting area.

In the embodiment of the application, since the preview frame has high requirement on real-time performance, the jitter intensity adjustment coefficient of the preview frame displayed in the video recording preview interface cannot be calculated by using the buffer frame, and the calculation of the jitter intensity adjustment coefficient of the video recording has the participation of the buffer frame, so that the jitter intensity of the preview is always far lower than the jitter intensity of the video recording, and the lower the jitter intensity is in the process of amplifying the recorded video, the larger the overall offset of the video is in the amplifying process.

The terminal device receives a third input, where the third input is an operation for amplifying the target shooting area in the video recording preview interface according to a target amplification factor, and the target amplification factor may specifically be an amplification factor for amplifying the target shooting area, for example, the target amplification factor may be 2 times the amplification factor, that is, the target shooting area is amplified twice.

In one embodiment, the target capture area is an area that appears in the video capture preview interface, and the target capture area may also be a focus area during video recording.

In one embodiment, the third input may specifically be an operation of sliding and amplifying the target shooting area by two fingers, an operation of dragging the magnification mark, a voice command input capable of realizing a response function, and the like.

In response to the third input, the terminal device zooms in on the target shooting area, and during zooming in, in one embodiment, since the jitter intensity adjustment coefficient of the video preview is determined according to the preview frame, and the jitter intensity adjustment coefficient for video recording is calculated jointly by the buffer frame and the preview frame, different jitter intensity adjustment coefficients may cause the preview picture and the recording picture to deviate during zooming in. At this time, the situation that the previewed picture and the recorded picture are inconsistent can be adjusted according to the first jitter intensity adjustment coefficient set by the user.

In one embodiment, the first center point may refer to an interface center point of the video recording preview interface, and in an alternative embodiment, the first center point may also be a center point set by a user in the video preview interface.

The second center point may be a focal point of the terminal device in the target shooting area during video recording in one embodiment, or may be a point manually selected by the user in an alternative embodiment.

In this embodiment of the present application, the situation that the previewed picture and the recorded picture are inconsistent may be that the previewed picture is offset, or may be that the recorded picture is offset, so in this embodiment of the present application, the first center point of the video recording preview interface and the second center point of the target shooting area in the recorded video frame may be controlled to be close to each other, at this time, the video preview picture and the recorded video recording picture in the video preview interface may also be offset towards the corresponding directions, so that the problem that the previewed picture and the recorded picture are inconsistent is solved to a certain extent.

Optionally, controlling the first center point of the video recording preview interface and the second center point of the target shooting area in the recorded video frame to be close to each other includes:

Determining a first offset of the first center point and a second offset of the second center point based on the first jitter intensity adjustment coefficient and a preview jitter intensity adjustment coefficient, the preview jitter intensity adjustment coefficient being a jitter intensity adjustment coefficient generated based on a video frame data set including only N frames of the preview frames;

and controlling the direction of the first center point towards the second center point, performing offset adjustment according to the first offset, controlling the direction of the second center point towards the first center point, and performing offset adjustment according to the second offset.

In this embodiment of the present application, the preview jitter intensity adjustment coefficient is a jitter intensity adjustment coefficient of a video preview, which is calculated according to a preview frame in a first video, and specifically is calculated according to a video frame data set including only all preview frames in the first video by the above-mentioned jitter intensity adjustment coefficient calculation method.

In the embodiment of the present application, since there may be an additional buffered frame in the video frame data set that generates the first jitter intensity adjustment coefficient, there may be a difference between the first jitter intensity adjustment coefficient and the preview jitter intensity adjustment coefficient.

In this embodiment of the present application, the offset degree of the video preview picture in the video recording preview interface with respect to the video recording picture is T, where t=k1-K2, K1 is a first jitter intensity adjustment coefficient, and K2 is a preview jitter intensity adjustment coefficient.

In one embodiment, the magnification also affects the offset of the video preview screen in the video recording preview interface relative to the video recording screen during the magnification. The larger the magnification, the larger the offset, which may specifically be magnification x T, for example, the magnification is 2 times, and the corresponding offset is 2*T.

Fig. 3 is a second schematic diagram of the display provided in the embodiment of the present application, as shown in fig. 3, including a first center point 31 and a second center point 32, where an offset is generated between the first center point and the second center point during the magnification process.

In this embodiment of the present application, the values of the first offset and the second offset may be different, and when the respective offset degrees cannot be determined, the values of the first offset and the second offset may be the same.

After the first offset and the second offset are determined, the first center point of the video recording preview interface can be further controlled to offset towards the second center point according to the first offset in the magnification amplifying process, and correspondingly, the second center point of the target shooting area in the video recording picture can also offset towards the first center point according to the second offset, that is, the first center point and the second center point are mutually approximated in the magnification amplifying process, and the corresponding video preview image in the video preview interface and the picture of the video frame recorded by the video can be correspondingly adjusted.

In one embodiment, after the magnification adjustment is completed, the first center point and the second center point also complete corresponding offset adjustment, and after the magnification adjustment is completed, the first center point and the second center point may be coincident on the final display interface, that is, after the magnification adjustment is completed, the content displayed on the video preview interface is identical to the content of the video frame recorded by the video, so that the situation that after the magnification adjustment is completed due to different jitter intensity adjustment coefficients, the content of the video preview is inconsistent with the content of the video recorded is avoided.

Fig. 4 is a third schematic diagram of the display provided in the embodiment of the present application, as shown in fig. 4, the first center point 31 and the second center point 32 may be displayed in the original video recording preview interface 21, and if the offset between the first center point 31 and the second center point 32 is T before zooming in, the offset between the first center point 31 and the second center point 32 is 2T in the video recording preview interface 41 that zooms in twice without adjusting the offset.

Fig. 5 is a schematic diagram of a display provided in this embodiment, as shown in fig. 5, in the process of magnification in the original video recording preview interface 21, if the second center point 32 of the target shooting area is at the lower left corner of the video recording preview interface 21, the first center point 31 is correspondingly shifted in the lower left corner direction, the shifted first center point 33 is obtained in the magnified double video recording preview interface 41, in the process of magnification in the target shooting area 51, if the first center point 31 is at the upper right corner of the target shooting area 51, the corresponding second center point 32 is shifted to the upper right corner of the target shooting area 51, the shifted second center point 34 is obtained in the magnified double target shooting area 52, and finally, in the magnified double video recording preview interface 41, the shifted second center point 34 and the shifted first center point 33 may be overlapped. The scenery which the user wants to enlarge is positioned at the same position on the preview interface and the video interface, so that the problem of inconsistent preview and video under high zoom is solved.

In the embodiment of the present application, since the offset adjustment process starts when the user starts magnification and stops adjusting until the magnification ends, the screen offset generated by offset compensation is synchronized with the magnification process, and the user does not feel uncomfortable visually.

Optionally, determining the first offset of the first center point and the second offset of the second center point based on the first jitter intensity adjustment coefficient and the preview jitter intensity adjustment coefficient includes:

obtaining offset degree information based on a difference value between the first jitter intensity adjustment coefficient and the preview jitter intensity adjustment coefficient;

and determining a first offset of the first center point and a second offset of the second center point based on the amplification factor for amplifying the target shooting area and the offset degree information, wherein the first offset and the second offset are equal.

In this embodiment of the present application, since there may be a certain difference between the preview video frame in the video capturing process and the actually enlarged recorded picture, the adjustment may be performed by the first jitter intensity adjustment coefficient and the preview jitter intensity adjustment coefficient.

In this embodiment of the present application, the offset degree of the recorded video frame relative to the preview video frame may be obtained by using the difference between the first jitter intensity adjustment coefficient and the preview jitter intensity adjustment coefficient, to obtain the offset degree information.

In the embodiment of the present application, because the different magnification factors further affect the amount of the recorded video frames relative to the preview video frames, the overall offset may be determined according to the product of the magnification factor of the target shooting area for magnification and the offset degree information.

In an alternative embodiment, since both the first center point and the second center point need to be adjusted, in order to ensure that the adjusted offset amounts are appropriate, the first offset amount and the second offset amount may be made equal, that is, the first offset amount and the second offset amount are half of the overall offset amount, and the first offset amount of the first center point and the second offset amount of the second center point are determined.

In the embodiment of the application, the integral offset is determined by further combining the amplification factor of the target shooting area through the difference between the first jitter intensity adjustment coefficient and the preview jitter intensity adjustment coefficient, and then the first offset of the first center point and the second offset of the second center point are obtained through the integral offset, so that the situation that after the magnification is amplified due to the fact that the jitter intensity adjustment coefficients are different, the content of the video preview is inconsistent with the content of the video recording is effectively avoided.
