Shane’s way is probably the simplest,
but here’s an idea:
doing your edit at 24 will definitely be simplest as the pictures will sync to the audio.
the simplest, fastest, cleanest, and cheapest way to get that to 25fps is to conform the final export in CinemaTools
but this will result in the audio speeding up.
so go ahead and cut your video at 24fps,
make a version of the AUDIO that plays SLOW
to do this, put the audio track in a 2fps sequence, with some slug, or a title generator,
export, open in Cinema Tools, and conform to 24.
(you need video for the conform to work)
when you have locked off your clip, cut against the correct audio,
copy the sequence,
replace the audio with the slowed down track,
re-adjust your cuts to maintain sync.
(obviously this wil be easier if there are quick cuts)
export, open in CT and conform BACK to 25.
am i crazy, or would that work?
you should test this with one take of the sync performance, if you have that.
oh and your footage may actually be 23.98, so double check that, too.
