I saw Jetrell Fo posted about film being 24fps, though I still wanted to post this.
Me and DJ are going to use this audio in our 97 SE project, and DJ had already synched the first reel of ANH but told me it was very hard. Then I got that idea that it might need a conversion from 24 to 23,976 fps, and I tried it myself and it was an almost perfect match with the digital broadcast version we're working with. (TB version, converted from 25 to 23,976 fps)
Though the software I used to convert the audio from 24 to 23,976 (BeSweet) is old and felt very outdated, since it forced every mono file to be converted to stereo during the conversion.
I also wonder what would be the easiest way to convert this from 44100hz to 48000hz? Or does a blu-ray accept audio being 44100 if we'd make a DTS track from this?
EDIT: Found out that eac3to could do this conversion properly. It was hard to find out how to make a script that would convert all audio files at once though.
eac3to is an excellent tool ;)
I've done near-perfect synchs of all three films to 24fps. It was the easiest way, as they do match the film frame rate. I've also managed to synch them by adjusting the playback sample rate to match (roughly, but perfectly adequately) to 23.976 in my first attempts.
Blu-Ray format accepts nothing less than 48KHz, but interestingly enough does support a true 24fps format in 720p and 1080p, in addition to the usual 23.976fps.
Have you reinserted the missing frames into the TB broadcast you're working on?
Synch should be very easy if you have, I managed to synch all three films in less than 6 hours to a frame-accurate video at its native 24fps frame rate, then just ran a sample rate conversion to 48KHz when they were all done. If you haven't then you may have to adjust/mix the DTS tracks in places to match it; I know that in the TB broadcast of Empire most of the missing frames are in the middle of reels, something like 12 frames out of the 15 or so that are missing. The rest of the time they are missing frames around reel changes, which should be much easier for you to work around should you choose that path.
