The first embodiment of the present invention relates to a method for editing a video of an event. The specific process is shown in Figure 1 and includes the following steps:

S11: Get pre-recorded game video.

In this step, the server obtains the pre-recorded game video through WIFI, 2G/3G/4G/5G and other networks, wherein the game video includes game audio and a picture synchronized with the audio, and the game video can be football, basketball, volleyball and other sports events Videos can also be entertainment activities such as cross talk and sketches, which are not limited here.

S12: Analyze the audio of the game to obtain the commentary audio and background audio.

In this step, the game audio is parsed, that is, the audio tracks contained in the game video are separated and distinguished according to the audio features to obtain the commentary audio and the background audio. For example, the change curve of the background audio is obtained (for example, the background audio is the background song being played ), in order to remove the background audio from the game audio, so as to obtain the data of the commentary audio; or, according to the characteristics of the commentator's timbre, etc., separate the commentator's voice from the game audio as the commentary audio, and use the remaining audio in the game audio as the commentary audio. Background audio, etc., the specific separation method of narration audio and background audio is not limited here.

S13: According to the commentary audio and the background audio, determine the effective score change time point of the video of the game.

Specifically, step S13 includes the following sub-steps:

S131: Determine the time point of the score change according to the audio commentary.

In this step, the narration audio can be recognized by means of speech recognition to obtain score information, and based on the score information, determine the score change time point corresponding to the score information, for example, by identifying "score, score, A ratio B, where A and B are keywords such as "numbers", so as to identify the score information in the commentary audio, and record the time point corresponding to the score information as the score change time point, as shown in Table 1:

Competing time AB team score 0:00:00 0:0 0:05:10 2:3 0:10:10 1:0 0:14:00 1:0 0:20:00 2:0 0:22:00 2:2 0:25:10 2:1 0:46:00 2:2 0:50:00 2:2 1:20:00 2:3 1:25:00 2:4 1:26:00 3:4 1:32:00 3:4

Table 1

S132: Obtain the decibel number at the time point of the score change in the game audio as the score decibel number.

Specifically, the decibel number at each score change time point in the game audio can be extracted as the score decibel number, as shown in Table 2:

Table 2

S133: Obtain the decibel number in the background audio as the background decibel number.

Specifically, the number of decibels in the background audio at every preset time period is obtained as the number of background decibels, and the number of background decibels is generally an integer, wherein the preset time period can be set according to actual needs, for example, it can be set to 30 Seconds, 1 minute, two minutes, 5 minutes, etc. For example, the decibels of the background audio are extracted every 1 minute as the background decibels, as shown in Table 3:

Competing time decibels 0:00:00 60 0:01:00 51 0:02:00 48 0:03:00 52 0:04:00 49 0:05:10 48 0:06:00 54 0:07:00 50 0:08:00 47 0:09:00 55 0:10:10 80 0:11:00 74 0:12:00 59 0:13:00 52 0:14:00 55 0:15:00 47 0:16:00 46 0:17:00 48 0:18:00 50 … …

table 3

S134: According to the score decibel number and the background decibel number, determine the effective score change time point of the game video from the score change time point.

In this step, the background decibel reference number may be obtained according to the background decibel number, and then, according to the difference between the score decibel number and the background decibel reference number, that is, the decibel floating number, from the score change time point to determine the effective score change time point of the game video.

The background decibel reference number may be obtained by calculating the frequency of occurrence of each decibel number in the background decibel numbers, and according to the frequency of occurrence of each decibel number, thereby obtaining the background decibel reference number.

In practical applications, the decibel data segment Di corresponding to each decibel number in the first M decibel numbers is determined by acquiring the first M decibel numbers whose frequencies appear in the background decibel numbers from high to low, where Di=( Xi+a, Xi-b), Di is the data segment corresponding to the i-th decibel in the first M decibels, Xi is the i-th decibel in the first M decibels, a is the first preset threshold, b For the second preset threshold, calculate the frequency of the background decibel number distributed in each decibel data segment, and obtain the decibel data segment with the largest frequency Vmax=Max(V(1), V(2)...V( i)...V(M)), where V(i) is the frequency in the data segment Di corresponding to the i-th decibel number in the first M decibel numbers, so according to the decibel data segment Dmax with the highest frequency, determine The background decibel reference number.

In this implementation manner, before determining the background decibel reference number according to the decibel data segment with the highest frequency, it may further include: judging whether the frequency Vmax of the decibel data segment with the highest frequency is greater than or equal to the first frequency Threshold, if not, expand the decibel data segment Di corresponding to each decibel number in the first M decibel numbers, that is, increase a or b or increase a and b at the same time, and obtain the decibel data segment with the highest frequency. Frequency Vmax, until the frequency of occurrence of the decibel data segment with the highest frequency is greater than or equal to the first frequency threshold. In this embodiment, the first frequency threshold may be 50%. In practical applications, the first frequency threshold may be set as required, which is not limited here.

Optionally, after the frequency Vmax of the decibel data segment with the highest frequency is greater than or equal to the first frequency threshold, the method further includes: acquiring the top P of the decibel data segment with the highest frequency from high to low. Decibel number, determine the decibel data segment D _i ' corresponding to each decibel number in the first P decibel numbers, and obtain the frequency of occurrence of the new decibel data segment with the highest frequency Vmax'=Max(V(1)', V (2)'...V(i)'...V(M)'), where D _i '=(X _i '+a',X _i '-b'), a'<a, b'<b, D _i ' is the data segment corresponding to the i-th decibel in the first P decibels, X _i ' is the i-th decibel in the first P decibels, a' is the third preset threshold, and b' is the fourth The preset threshold, V(i)' is the frequency in the data segment Di' corresponding to the i-th decibel number in the first P decibel numbers, and re-determines whether the frequency of the decibel data segment with the highest frequency is greater than or equal to The second frequency threshold, if not, expand the decibel data segment corresponding to each decibel number in the first P decibel numbers, and re-obtain the frequency of the decibel data segment with the highest frequency, until the decibel data segment with the highest frequency appears. The frequency is greater than or equal to the second frequency threshold, so that the range of the decibel data segment with the highest frequency can be continuously refined, and the accuracy of the background decibel reference number can be further improved.

In this embodiment, P is equal to M, and the first frequency threshold is equal to the first frequency threshold. Of course, P may not be equal to M, and the first frequency threshold may not be equal to the first frequency threshold, which is not limited here.

It is worth mentioning that the above steps can be repeated until the difference between the frequency of the decibel data segment with the highest frequency and the frequency of the decibel data segment with the second highest frequency is greater than the fourth preset threshold, and stop. calculation, thus ensuring the accuracy of obtaining the background decibel reference number.

For example, in this embodiment, the acquired background decibel reference number is 50 decibels, then the game time, AB team score, score decibel number and decibel floating number are shown in Table 4:

Competing time AB team score decibels Decibel float 0:00:00 0:0 60 10 0:10:10 1:0 80 30 0:14:00 1:0 55 5 0:20:00 2:0 78 28 0:25:10 2:1 81 31 0:46:00 2:2 56 6 0:50:00 2:2 85 35 1:20:00 2:3 78 28 1:25:00 2:4 75 25 1:26:00 3:4 84 34 1:32:00 3:4 60 10

Table 4

Since the commentator may predict the score, or mention the scores of the participating teams in the previous game, etc., the same score may occur at different time points of the score change, and due to the fact that during the game In the wonderful moments such as scoring a goal, the cheers at the scene and the voice of the commentator will cause the decibel number to be larger than the normal situation due to factors such as excitement, so that the same score can be judged according to the size of the decibel floating number. The time point corresponding to a score is the real score moment. Specifically, when the same score occurs at different score change time points, the score change time point with the largest decibel floating number is the effective score change time point.

For the data in Table 4, the score of 1:0 corresponds to two time points 0:10:10 and 0:14:00, and the decibel fluctuations are 30 and 5, respectively, and the time point with the largest decibel fluctuation is 0: 10:10, at the same time, remove the time point 0:14:00, and so on, if the score is 2:2, take 0:50:00, if the score is 3:4, take 1:26:00, then the final result is valid The time points of the score changes are shown in Table 4:

Competing time AB team score decibels Decibel float 0:10:10 1:0 80 30 0:20:00 2:0 78 28 0:25:10 2:1 81 31 0:50:00 2:2 85 35 1:20:00 2:3 78 28 1:25:00 2:4 75 25 1:26:00 3:4 84 34
