Abstract

A video generating method, an apparatus, an electronic device, and a computer-readable medium are provided. The method includes: acquiring a first video set and an audio material; determining a first music point of the audio material according to an amount of the video materials in the first video set; generating, according to a sorting order of the video materials in the first video set, one video clip for each first music clip in the audio material by respectively using one video material, so as to obtain a first video sequence; adjusting, in response to detecting an editing operation on the video clip in the first video sequence, the video clip in the first video sequence, so as to obtain a second video sequence; and splicing together video clips in the second video sequence, and adding the audio material as a video audio track to obtain a composite video.

First claim

What is claimed is:

1. A video generating method, comprising:
acquiring a first video set and an audio material, the first video set comprising a plurality of video materials;
determining a first music point of the audio material according to an amount of the video materials in the first video set, wherein the first music point is used to divide the audio material into a plurality of first music clips, and an amount of the first music clips is same as the amount of the video materials in the first video set;
generating, according to a sorting order of the video materials in the first video set, one video clip for each first music clip in the audio material by respectively using one video material, so as to obtain a first video sequence, wherein the first music clip and the video clip corresponding to each other have a same duration;
adjusting, in response to detecting an editing operation on the video clip in the first video sequence, the video clip in the first video sequence, so as to obtain a second video sequence, wherein the adjusting, in response to detecting an editing operation on the video clip in the first video sequence, the video clip in the first video sequence, so as to obtain a second video sequence further comprises:
rotating, in response to detecting a rotation operation on a sixth video clip in the first video sequence, the sixth video clip to obtain a seventh video clip, and
replacing the sixth video clip with the seventh video clip in the first video sequence to obtain the second video sequence; and

splicing together video clips in the second video sequence, and adding the audio material as a video audio track to obtain a composite video.

2. The method according to claim 1 , wherein adjusting, in response to detecting the editing operation on the video clip in the first video sequence, the video clip in the first video sequence, so as to obtain the second video sequence, comprises:
adjusting, in response to detecting an adjustment operation on a sorting order of video clips in the first video sequence, the sorting order of the video materials in the first video set according to an adjusted sorting order of the video clips, so as to obtain a second video set; and
generating, according to a sorting order of video materials in the second video set, one video clip for each first music clip in the audio material by respectively using one video material, so as to obtain the second video sequence, wherein the first music clip and the video clip corresponding to each other have a same duration.

3. The method according to claim 2 , wherein adjusting, in response to detecting the adjustment operation on the sorting order of the video clips in the first video sequence, the sorting order of the video materials in the first video set according to the adjusted sorting order of the video clips, so as to obtain the second video set, comprises:
displaying a first presenting interface of the first video sequence;
moving, in response to detecting the adjustment operation of moving an identifier of a video clip in the first video sequence from a first sorting position to a second sorting position in the first presenting interface, the video clip to the second sorting position, and determining the adjusted sorting order of the video clips; and
adjusting the sorting order of the video materials in the first video set according to the adjusted sorting order of the video clips, so as to obtain the second video set.

4. The method according to claim 3 , wherein adjusting, in response to detecting the editing operation on the video clip in the first video sequence, the video clip in the first video sequence, so as to obtain the second video sequence, comprises:
deleting, in response to detecting a deletion operation on a first video clip in the first video sequence, a first video material from the first video set to obtain a third video set, wherein the first video clip is generated based on the first video material;
determining a second music point of the audio material according to an amount of video materials in the third video set, wherein the second music point is used to divide the audio material into a plurality of second music clips, and an amount of the second music clips is same as the amount of the video materials in the third video set; and
generating, according to a sorting order of the video materials in the third video set, one video clip for each second music clip in the audio material by respectively using one video material, so as to obtain the second video sequence, wherein the second music clip and the video clip corresponding to each other have a same duration.

5. The method according to claim 2 , wherein adjusting, in response to detecting the editing operation on the video clip in the first video sequence, the video clip in the first video sequence, so as to obtain the second video sequence, comprises:
deleting, in response to detecting a deletion operation on a first video clip in the first video sequence, a first video material from the first video set to obtain a third video set, wherein the first video clip is generated based on the first video material;
determining a second music point of the audio material according to an amount of video materials in the third video set, wherein the second music point is used to divide the audio material into a plurality of second music clips, and an amount of the second music clips is same as the amount of the video materials in the third video set; and
generating, according to a sorting order of the video materials in the third video set, one video clip for each second music clip in the audio material by respectively using one video material, so as to obtain the second video sequence, wherein the second music clip and the video clip corresponding to each other have a same duration.

6. The method according to claim 1 , wherein adjusting, in response to detecting the editing operation on the video clip in the first video sequence, the video clip in the first video sequence, so as to obtain the second video sequence, comprises:
deleting, in response to detecting a deletion operation on a first video clip in the first video sequence, a first video material from the first video set to obtain a third video set, wherein the first video clip is generated based on the first video material;
determining a second music point of the audio material according to an amount of video materials in the third video set, wherein the second music point is used to divide the audio material into a plurality of second music clips, and an amount of the second music clips is same as the amount of the video materials in the third video set; and
generating, according to a sorting order of the video materials in the third video set, one video clip for each second music clip in the audio material by respectively using one video material, so as to obtain the second video sequence, wherein the second music clip and the video clip corresponding to each other have a same duration.

7. The method according to claim 6 , wherein deleting, in response to detecting the deletion operation on the first video clip in the first video sequence, the first video material from the first video set, comprises:
displaying a second presenting interface of the first video sequence;
displaying, in response to detecting a selection operation on the first video clip in the first video sequence in the second presenting interface of the first video sequence, a first clipping operation interface for clipping the video clip from the first video material; and
