Need some experienced ears here (i don't have those...)
I'm doing a huge project restoring old movies that have to go to DVD.
Since i'm in PAL, the movies are scanned speeded up to 25 fps.
(sources are 24, 18 and some unknown rates from really crappy cams, even for those days (war zone shots)
So there is a 1:1 frame relation. But, since i've ingested as 25 fps and i'm going to 23.976 -> 29.97, the audio has to change.
Since it's speeded up the easy way, i do not have to worry about pitch changes.
Here is my idea:
Change the sample rate in the .wav files i have ingested, and save that with a normal 48000 sample rate.
Nothing changes (not even the file size, since there is NOTHING altered except the playrate.
I've made an application to do so. (you can set any duration and either alter the sources sample rate to match so, or export with an alternative length but original sample rate in the file) But, since my ears are way out of spec to judge objective if my theory works, i need some people to do some tests.
In return, you get a full working version of the application, and lots of love and goo Karma....
Its windows only now, but if you want a mac version, i can arrange that too.
mail me direct if you want to try it, firstname.lastname@example.org
(if it works i'll put up the final version on my site as a free/shareware program)
