Combining 24F & 24P
Hi,
I have HDV footage shot in 24F on a Canon XH-A1, and will have new material coming in from a Canon HV20 (24P). Before getting myself into a jam, I want to make sure I have the best workflow for combining these two formats.
I’m on MacBookPro with FCP 5.1.4, OSX, and I understand I can do one of two things:
1) keep working in 24F, bring in the new 24P footage and remove pulldowns (though I’m still not sure the best way to do this, so if you recommend this tactic, let me know your preferred pulldown method too)
2) upgrade to FCP 6, redig the 24F with ProRes 422, which would also accept the new 24P upon capture. (I understand the ProRes will make the 24F look better anyway — is that true?)
Any workflow suggestions are welcome!
Thanks, and I apologize if this has been posted before.

The HV20 records 24(23.98) within 60i even though it has a progressive chip.
What are your sequence settings with the XH-A1 footage? 23.98 or 60i?If you are in 23.98 use JES Deinterlacer on the HV20 footage and you will be all set.
https://www.xs4all.nl/~jeschot/home.html#DEIIf your current sequence is HDV 60i, then you need do nothing but bring in the HV20 footage as is.
24F is Canon’s way of saying they are not using a progressive chip but still give you 24p. This has been the source of much confusion and probably a loss of a lot of sales for Canon especially considering the quality of the XH-A1 footage that IS progressive once it is brought in properly to a 23.98 project.

Thank you! When I get the footage, I’ll let you know if I run into any troubles.
Curious, though. What did you mean by this: “especially considering the quality of the XH-A1 footage that IS progressive once it is brought in properly to a 23.98 project.”
Also, side note, I’m currently experiencing immense difficulty trying to print this 23.98 sequence to tape using the XH-A1. I’ve followed all the recommendations on-line but the best result I’ve gotten is 8 minutes of normal footage, and then the tape seems to stutter — it gets hung up for a few frames, the TC pauses, then jumps ahead to catch up with itself. Any advice?
Thanks,

Answer to what I mean…
If you shoot in 24f on a XH-A1, after you do a reverse pulldown (with JES Deinterlacer or other tools) you end up with 24P no joke.Which instructions are you following from on line?
I am guessing that you need to add the pulldown back in with Cinema tools to convert the 23.98 back to 60i before printing to tape. This is a good example of why Canon doesn’t say the camera records in 24P.Are you familiar with interlaced “fields” versus “frames”?
