25p to 24p – is it magical?
After questioning the client extensively and after post – i am now informed that 25p is a no no for the project. Just shipped the drives a week ago. I dropped the 25p sequence onto a new 24p sequence. The sequence is now 30 seconds shorter (no surprise there) but lip flap is not seen and edits are still following narration. In other words – it’s working. Am i missing something? Is it as magical as that?
thanks in advance

How do you slow the framerate and yet, shorten the video?

Thanks for the quick Reply Tom – right you are. There’s another change as client needs to go to 30p!
Original Time of sequence on 25p timeline (xdcam source footage 25p) 00:04:55:20
Created new sequences from the file/new/sequence/etc
Then copy pasted everything to that..
Time on 30p sequence 00:04:55:00
20 frame difference yet no lip flap even in last 30 secs of video – maybe not enough to count?
Perhaps a longer program would yield more lip flap later?
I’m not looking for problems – I am happy…and incredulous -
Dropping 25p material onto a timeline that has another frame rate shouldn’t actually result in a length change as a 5 second clip should be 5 seconds on any frame rate timeline…the material would not be a frame-for-frame match as the mismatch would result in frame interpolation…but the length should be the same within a couple frames.

To convert 25p to 24p interpret the 25p master clip to 24p (right click ‘interpret’ and change to 24fps) then put that clip in a 24p sequence. Then for the audio you’ll need to do a 4% speed up while preserving pitch in Audition (you’ll need to experiment there – can’t remember best way to do it)then drag that new audio file onto the 24p timeline.
