Found that the mp4 file is not supported
Recently, I downloaded a video of mp4 format and I also downloaded AVI-Mux_GUI-1.17.8 to fix the out of sync audio problem but I found that the mp4 file is not supported in it then I tried to convert the video to .AVI so I loaded avidemux_2.5.2_full_win32 and tried to load the file but I got the following warning with the weird message. Have any idea to fix this problem? Suggest me properly. Thanks.
If the file is using B-frames as reference it can lead to a crash of shuttering. Avidemux can use another mode which is safe but you will lose frame accuracy.
