DV 23.98 to Uncompressed NTSC 29.97 (Beta) – 1 or 2 steps????
I have a DV sequence that’s edited at 23.98. I need to output to Beta at normal NTSC 29.97 (8 or 10-bit, don’t care right now). I plan on using the Nattress Film converter to add the pull-down necessary to bring the DV sequence to 29.97. I then planned on dropping the sequence into a new Uncompressed 8 or 10-bit timeline and rendering so I can have a facility output the file straight to Beta. Can the above 2 steps be done at once? Do I have to render the 23.98 first to 29.97 and THEN drop that into an uncompressed timeline? Or can I put the Nattress filter on the sequence while it is already in an uncompressed timeline? That way there’d be one render (probably long). I just wasn’t sure if this workflow made sense or is there a better (read “faster”) way?

Use the 8-bit uncompressed settings. Beta is 8-bit. You can drop it into the 8-bit timeline, then add the filter, then render. I am not quite sure you need the filter, as Graeme is oft to say that FCP adds back the pulldown on output…but I’d defer that to someone with more knowledge in this area.
Why did you edit 23.98 if you are outputting 29.97?

Well, first of all, I just wasn’t sure whether the render would work correctly when applying the Nattress Film Converter filter to the sequence while it was in an 8-bit timeline. Since the input video is DV I wasn’t sure whether the filter would get confused trying to render the added frames in an 8-bit timeline that has a different frame size. DV is 720×480 and Beta would be 720×486. I wasn’t sure the filter would work correctly if it’s output wasn’t the same frame size.
Also, I know FCP can added pulldown on output, BUT my Dual G4 1.25ghz is not up to the task, it won’t work, keeps dropping frames. Plus, that output is only to DV, i’d still need to get to Beta.
Lastly, we edited at 23.976 cause we wanted to output a 24p DVD, which worked great. I thought all along that adding the pulldown for an output to tape would be no problem. Since it is a problem for me I’m not opting to use Nattress Standards Conversion Film Converter filter.

These days, high end capture cards should be able to add pulldown on output. This was not the case when the filter was written.
Since FCP5, these filters all work only on movies, not sequences due to Apple breaking things that used to work, so you’d have to do two stages. The render to add 3:2 is actually pretty quick though.

Thanks for the info. So, can I take a DV 23.976 self-contained Quicktime to a facility and they can output to BetaSP while adding the pull-down via a card? (What cards do this?) Therefore saving me these extra steps of creating an NTSC 29.97 file. I wasn’t sure if a DV movie can go out to something other than DV, even through a card. I thought it needed to be 8-bit uncompressed if that’s what you were outputting to. Some illumination would be greatly appreciated.
