Playing out 23.98 to tape
Hi,
Can anyone help me, I am flummoxed.
I have been asked to rescue someone’s project in a very short space of time.
The project is a feature doc. It was shot on 2 cameras: A JVC HDV 720p 23.98 and a Panasonic HVX200 at 720p 25fps. This has all been edited together onto a HDV720p timeline at 23.98 fps in FCP. They used 5.0.4 to edit eith, so no “open timeline”.
The project has to be finished on HD-CAM 1080 23.98 to be sent to LA, where it will be turned into a FCP for projection at DIgital Cinemas in the US.
The first thing I did was to copy the sequence and then change the compressor from HDV to Apple Pro Res 422(HQ) 720p 23.98. I rendered that and noticed that some of the 25fps shots juddered. We exported those out, put them through compressor changing their fps to 23.98 and re-inserted them in the time line. Happy, we rendered that and made a QT 720p 23.98.
I have then used compressor to upres that to 1080 720p. I plug in the HDCAM deck HDW-M2000P, set the frequency to 23.98. I create a new sequence at Apple Pro Res 1080p 23.98, use Video Out Blackmagic HDTV 29.976, connect Deck to computer using HD-SDi Blackmagic HD Extreme 2 and…nothing.
I am getting audio, but no sniff of video. I have experimented with different video out options.
Does anyone know what I am doing wrong?
Thanks in desperation

PS, I live in PAL land, and am finding the maths for the difference between 24PsF and 23.98PsF confusing. This is to do with NTSC I suspect.

The much, much better way to do this is to use Cinema Tools and conform the PAL to 23.98. Conform, not convert, is better because you won’t have redundant frames.

Sounds like you’re doing everything right on the FCP end. But the deck needs to be set to 23.98 frequency. Changing the frequency of an HDCam deck is very tricky. It’s not even in the user’s manual. Sorry, I wish I remembered all the steps but I don’t.

Hey Sean,
Thanks. We got it all sorted. It turned out it was fine, except my SD monitor can’t play back 23.98. I rented a small HD field monitor, realised I was getting a picture and crashed it out, as timecode exactness wasn’t an issue.
It’s weird about setting frame rates on the desk. It is actually very easy to do, but is not in the manual, you are right.
Good luck with it all, and thanks for responding.
Best
