Version 2.9.4 has an audio delay feature in VLC. I can't find that in version 2.4.6
Anyone, any way to delay audio in vers 2.4.6?
A workaround could be to just add some silence to the beginning of an audio clip using something like Audacity?
It is not an audio clip, it is an MP4 video with audio
There are utilities that can fix out of sync videos, would this be of interest/help?
Yes, please, but once this issue is resolved: Crashes When Trying To Open A Saved Service, I can go back to 3.0. t was working fine for me except for this.
There may be better ways of doing this but this works for me. I first use VLC to work out how much I need to delay or advance the audio. Then I use ffmpeg with the following command line to resync the video permanently:
ffmpeg.exe -i "input_filename.mp4" -itsoffset -0.4 -i "input_filename.mp4" -map 0:v -map 1:a -c copy "output_filename.mp4"
The -0.4 is the adjustment to the audio stream in seconds and can be positive or negative.
