Capture/Frame Rate Problems
Hi all,
So I’ve received 70 tapes-worth of .avi files. This footage was shot in 24p (or 24p advanced) on a Panasonic DVX100b, but captured in 30p on Sony Vegas.
Now I have two options:
1) Re-capture all of it in FCP.
or
2) Convert all the files to .mov and then to 24p.
I’ve tried the first option, but I’ve encountered a lot of problems with “timecode breaks” (I know they don’t exist because the first assistant editor had no problem with that).
I would greatly appreciate it if someone could help me choose the best option and then guide me through the process.
Infinite Thanks,
– Adrian Fernandez

Stop. If they digititzed 24P tapes as 30P, then you need to throw away all of that useless crap and redigitize the tapes properly.
Do not pass go, do not collect $200, do not try to convert the 30P material back to 24P in software. You will only degrade the picture quality.

Since we’ve already ascertained that the 1st assistant screwed up the capture with the wrong frame rate, I wouldn’t assume that he dealt with the TC breaks properly, either. In fact, I’d assume that he did everything in exactly the worst way possible and forget about anything that he did to start with.
Have you actually checked to see that these tapes have continuous TC? If the camera was set to free run or time of day, then you will certainly TC breaks every time the camera stops.

Should I run through the tapes and check for time breaks anyway?

OK, that tells us something. Step through the footage one frame at a time and look at the fields. If it’s shot 24PA, then you should see a pulldown pattern of 2:3:3:2, which looks like 2 progressive, 1 interlaced and 2 progressive frames. If it’s “regular” 24P, you should see a 2:3:2:3 pattern, which gives you 2 progressive, 2 interlaced and 1 progressive frame.
If you don’t see either of those patterns, then you don’t have 24P material. You’ll either see every frame interlaced or progressive (30i or 30P).
