I want to add second audio stream to video from another video.
video 1: mp4 x264 AAC audio
video 2:Avi Xvid MP3 audio (audio taken from it)
The way I tried to sync the audio was by opening both videos with Avidemux and measure the difference of timestamps between identical I-frames and set the exact delay.
I was surprised to find out the new audio was not in sync (constant delay) by quite a big margin.
Can anyone think of a reason?
Maybe an original delay resets when I apply the new delay?
