I have R3d files at both 23.976 and 29.97 that are destined for the same timeline in Premiere Pro CS4.

I assume that I will have to conform them all to either 23.976 or 29.97 for editing. (Final output is broadcast at 59.94i)

Can Cineform make this conversion and what is the proper method? Also, which way would you go...all to 23.976 or to 29.97?

29.97 run fine on 60i, 23.976p does not. While I would not have shoot that way, so I don't have direct experience in the needed fix, you need to add pulldown to you 24p source (rendering it out to 60i.) You can do that in After Effects. With you 24p bumped to 60i, you can mix both on a 60i timeline.

Hi

I have not tried this but cant You just interpret footage (in PP) to conform the FPS as the difference is not noticeable?
I dont know if this is possible in PP4.... just throwing out an idea that might work (fingers crossed)

You can batch convert all of your source files in AE:
Import all 24p source files into AE
Select them all and drag them to the Comp button (3rd button on the bottom of the Project panel)
Select "Multiple Compositions" from the resulting dialog, and check the "Add to Render Que" box
In the render que, select "Render Setting"
Set Field Render to "Upper Field First" and the 3:2 Pulldown below that to WWSSW (the bottom choice)
You can use the template option to create a preset, and apply these settings to every comp in the que
Render each item to a new Cineform 29.97i file at your desired settings
These will be a lot easier to edit together with your other 29.97i footage in Cineform's CS4 editing mode

Depending on how much footage you have to convert, you may want to look into upgrading to CS5, which can edit 24p footage with 30p footage quite smoothly, if MPE is enabled. I used that capability a lot on my last project to intercut 30p Canon 5D footage with 24p film scans. It works so well that I can no longer detect footage at the wrong framerate based on the performance hit you used to see in CS4.

Thanks for the advice. I had not considered editing my final in 60i. I thought that finishing the final edit in 24p was the way to go, after which I would have it output to 60i.

So, just to make sure, are you essentially recommending that I conform my clips as described above to a 60i timeline for final? Thanks.
