I would like to try and test changing the tempo of the audio in a video without losing sync and without having to blend or merge frames.
At 25fps, dropping 1 frame would allow the the audio to be pitched/time stretched by 4% and dropping 1 frame every 2 seconds would allow for 2% I understand how to modify the audio with atempo but am not sure of the best method to drop one frame every second or every other second - is it possible with a standard filter command? _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
