The newer Audacity has some features I had not explored before.
One of the menu options for file display shows me a count of 16 dropped frames in an audio
from a play on video. That play has lost sync after I made a Part One and Part Two.
Please say how the dropped frames info is determined and if I can use that to help with
audio sync with video. MKVToolnix is the usual tool I use if I change audio formats – replace
one with another. Sync problems also develop if visual effects are used such as fade outs. I
have no idea why this is.
Looking at my audio and video, the actual file size is extremely close-- less than a second.
But is there a way to set my delay needed to regain sync as a calculation of audio length and
video length? Or a tool that accomplishes that after the editing problems noted above.
I’ll see if I can get a screen shot posted when I’m in one of those audio files from the video.
The big question is since: the audio can be adjusted when it goes out of sync, does anyone here
have a solution just from general knowledge such as a program I’m not aware of as to what amount of micro seconds
fixes it. I have watch a lot of out sync scenes but frankly I can never tell if the adjustment should be
made forward or backward: I can’t see it correctly. Or tell if it it’s progressing (getting worse) as the scene plays.
Sometimes you can catch a peak-- boom or scream etc, mark that while listening and find the peak in
the wave form. Then take the time stamps of that audio and video and convert to microseconds, add or subtract and do the adjustment. It’s a real pain and I’ve only been able to get all the steps straight once.
