Problems solved by technology

Another way is to reduce the number of frames. For example, 24 frames are usually displayed in one second. Removing some of the frames can also achieve the purpose of compressing the video size, but it will cause the problem that the playback is not smooth.

Embodiment Construction

[0030] The embodiment of the present invention provides a method and device for compressing video size, which realizes that under the premise of keeping the sound track unchanged, the same picture is used to represent the picture whose content has not changed when synthesizing video files, which can achieve the effect of not affecting the video. The playback effect can also compress the video file size.

[0031] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the following The described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creativ...

Abstract

The embodiment of the invention discloses a method and device for compressing a video. The effect of compressing a video file without influencing the video playing effect can be achieved when the samepicture is used for representing the picture without content change in the video file synthesis in the premise of unchanging a sound track. The method for compressing the video comprises the following steps: performing screen recording according to an acquired recording instruction; judging a view state in the current screen recording through a kernel, replacing the displaying of all views in thedisplay preset duration with the first picture of the screen recording in the preset duration if the view state in the current screen recording is unchanged in the preset duration.

Description

technical field [0001] The invention relates to the field of video recording, in particular to a method for compressing video size. Background technique [0002] Screen recording generally records the picture and sound separately, and then synthesizes the picture and sound into a video file. [0003] During a speech, it usually takes a certain amount of time for the speaker to explain the content of the same page of the document, so there may be situations where the content of the document does not change for a period of time, but the recorded voice changes. [0004] There are two existing technologies for compressing video: one is to achieve the purpose of compressing video size by compressing video quality, and the image will become blurred like compressing a picture. Another way is to reduce the number of frames. For example, 24 frames are usually displayed in one second. Removing some of the frames can also achieve the purpose of compressing the video size, but it will ...
