23.976 edit -> 29.97 master
I’m working on figuring out something before I agree to a job and wondered about how to accomplish this workflow. A client has shot a bunch of footage at 1080/23.976 and the show master has to be 1080/59.94. If I capture and edit at 23.976, is it true that the Media Composer/Nitris can’t automatically add the appropriate pulldown on output? I’ve tried a couple of tests and it seems to stutter and choke. I don’t think I should have to use a software render to make this work – I know the Kona hardware and FCP can handle this automatically, so what is the best way to handle it with Avid hardware? I don’t know much about the Media Composer’s capabilities regarding frame rate conversion, but I assume if I change the frame rate of the sequence, it’ll want to render the whole show. Can/Should the original footage be captured somehow at 59.94 and the edit done at that rate instead? I’m sure other people are running into this workflow and hopefully someone has an idea. I guess I can rent a Teranex or other cross-converter to hang on the end of the output to do it, but I’d like to know if my hardware/software can support what I think is a simple pulldown add. Thanks for your input.

Yes, with Avid hardware it will output 2:3 pulldown from your 23.976p sources to 59.94i master. What system and hardware?
You certainly can edit at 59.94i wuth the pulldown included if the distribition master you need is NTSC and 1080i.

I believe the system is Mac OS X 10.5.x. The Avid hardware is Nitris DX. The software is Media Composer 3.x (all the x’s are because I’m home now from work so I don’t remember). I am curious how to enable the pulldown – forgive me as I am mostly a FCP guy and have some SD experience with Adrenaline but the Nitris is new to me. I’m at least glad to know it’s possible.

Under the Tools menu, Video Output. That’s where you will see output and down conversion options. Select 1080i/59.94.

OK, I got somewhere, but not where I want to be yet. I captured some clips at 1080/23.976PsF and have them in a sequence with no other material:
I found the cross-convert options in the Video Output tab and set them this way:
My HD monitor now shows the sequence playing with 2:3 added. Great! Now, I want to Digital Cut to HDCAM-SR at 1080/59.94i:
I set an in point on the tape and my sequence is ready, I click execute and this happens:
I tried to reset the machine, but it wouldn’t work, no matter what. I then faked it out to tell Media Composer that I was hooked up to the same deck but with a 24P profile, which let me execute the cut, but it bailed about 1.5 seconds in with no error message. So close!
Any ideas? I am new to the HD hardware and workflow on Avid but I was pretty sure I didn’t leave anything out and tried what I could think of to work.

Also, I noted this passage in the manual for Media Composer:
“Crossconvert and downconvert options that change the edit rate are not supported for digital cut. For example, if you have a 1080p/23.976 sequence, you can preview the sequence at 1080i/59.94. 720p/59.94. or NTSC 30i. But when creating the digital cut, use the native format of 1080p/23.976.”
There is still clearly something I’m missing.

Any ideas? I am starting to resign myself to the fact that it doesn’t work.
