Hello,
This is a really basic question. But after searching on google and testing for hours… I dont find the correct answer, I ask this here. I know it’s not an “audacity” question but well. If anybody can help…
I need to put the audio from a video that is 24fps to the video with the same content that is 23,976fps.
It has of course to be synchro.
So, basicaly I have to convert a 24fps audio to a 23,976 audio.
Every attempt is a failure. On goodle, it says it should be this on the properties: 24000/1001. But that doesn’t match at all.
I tried 24000/999, same. I also tried many other values to test, nothing seems to be the correct value… It gives me a headache.
Any help?

So, that’s (24 - 23.976)/24 = 0.001. That’s 1 second every 1000 seconds (~17 minutes). Is that about what you’re seeing?
And you want to go to 23.976 from 24, so you want to go slower, right?
Try the Speed Change effect with a Speed Multiplier of 0.999.
On goodle, it says it should be this on the properties: 24000/1001.
Depending on the software/effect “100%” sometimes means be 100% faster than the original (twice as fast) or 100% of the original (no change).
You’re using Effect > Change Speed, right? Not either of the other two.
1.001. That is totally the correct number, you just did it wrong.
30 / 1.001 = 29.97002997002997 NTSC Frame Rate
24 / 1.001 = 23.976023976023976 3:2 pulldown for US video projection of 24-frame film.
Are you sure of your originals? Our company made equipment that would shoot theatrical film at 23.976.

Sometimes you can get increase accuracy in these effects by specifying the old and new target selection lengths.
Thank you very much.
1.001 was the right setting for my need here! It worked finally!
What I like about this forum is that you are very reactive and helpful!
Great help, thans again!

So as up this thread, either your original master or your off-speed tracks are wrong. There are very few options.
Third time:
What happens when you use the Beginning and End time settings in Effect > Change Speed instead of trying to manage the arithmetic by hand?
