Embodiment 1
[0032] Such as figure 1 As shown, the embodiment of the present invention provides a video editing method, comprising the following steps:
[0033] Step 1, preprocessing the original audio and video files to be edited to obtain samples with a lower bit rate. A sample is a low-level version of the original audio and video file. It adopts a fixed package format, a fixed encoding standard, a proportional reduction in resolution, a lower frame rate, and a lower encoding quality. Therefore, the bit rate of the sample is much lower than that of the original audio and video file.
[0034] Specifically, there are many material packaging formats, such as mp4, flv, mpegts, webm, mpg, mkv, rmvb, avi, vob, rm, etc. There are many audio and video coding standards used in the material. Taking video coding standards as an example, there are h.261-h.264, hevc, av1, vp6-vp9, etc. Existing webpage players support relatively limited encapsulation formats and audio and video encoding standards....
Embodiment 2
[0045] An embodiment of the present invention provides a video editing system, including:
[0046] The preprocessing module is used to preprocess the original audio and video files to be edited to obtain samples with a lower bit rate;
[0047] The sample editing module is used to perform non-editing operations on the sample: for the editing operation, mark the sample playback time axis, and the editing system automatically records the editing time information; for the screen cutting operation, use a rectangular tool circle on the sample playback screen The editing system will automatically record the proportion information that needs to be cut out; for the mosaic operation, mark the mosaic time range on the sample playback time axis, and use the rectangle tool to circle the required area on the sample playback screen. In the mosaic area, the editing system automatically records the mosaic time information and position size ratio information; for the field effect and audio mixi...
