HI this paragraph is a detail of problem please skip to question if its too much, So I download Movies from the internet and they are not synced with audio correctly. Some movies’ audio are hastened and some are delayed. So I tried a program like “virtualdub” so 1) they obviously stated that the video has a Variable Bitrate (VBR) Audio and I may encounter sync problems in sync in some players and they recommended full processing mode (so maybe they would fix it I haven’t tried it because I have slow computer *I Use Direct copy method*). 2) I sync the audio according to speech on first scene and it works perfect. 3)BUT it works for a scene and the next scene (approx. 20 mins later) Audio is no longer synced ! it hastens AGAIN. so I use the program again and a cycle begins. I sync according to one scene the other is not synced, and then the scene after isn’t synced as before the first adjustment.
Question: Is there a way to fix the audio sync problem?? as I suggest maybe convert VBR audio to CBR? maybe a program would fix VBR Audio?
