Saving the same video clip twice will yield different results

[kongzhecn]

Saving the same video clip twice will yield different results. Specifically, there may be differences in the starting frame of the same video clip, with the first saved video frame having motion and the second saved video frame being stationary.

Expected Behavior

The movements of the two video clips should be completely consistent.

Actual Behavior

The comparison results are shown as follows (I only captured the different frames in the video.):

4.19.mp4

The whole videos are as follows:
