How to Solve Handbrake Video and Audio Out of Sync Issue?
“Audio and Video out of Sync – Hi, I just started using Handbrake to change the video files from .mkv to .mp4 so I can play them on my tv. but now some of them have the audio and the video out of sync. The original video is good (.mkv files), but when I change the format, the new video is out of sync with the audio. I have tried setting it with "constant framerate" like many people recommended, but it doesn’t solve the problem. The problem happens just as the video starts, the audio kicks in like 1 or 2 seconds before the video and it is like that until the end. Thanks a lot for your help.”
