If I have a movie file already exported in 23.97p but I need it in 29.97i, can I just use Compressor?

I have a huge timeline which often gives me the dreaded out of memory error when exporting. I finally got it to export....but discovered the client needs it in 29.97i. Can I get good results by just taking the exported Pro Res file, putting it in Compressor, and exporting to the right frame rate? I'm pretty sure from research the answer is yes but I want to make sure.

That would depend on the frame rate of your original media and the sequence settings of your timeline, neither of which you've mentioned.

Point taken David.

Frame rate is 1080 and original sequence is 23.97.

If your source was 23.98, and you exported 23.98...and you need to deliver 29.97 interlaced...Yes, you'd use Compressor. And this formula:

23.98 to 29.97 via Compressor:

1. Drop clips you want to convert into Compressor

2. In Compressor, select your video then right click and choose NEW TARGET WITH SETTING > APPLE > FORMATS > QUICKTIME > APPLE PRORES 422 (HQ). Or pick whatever codec you like to work with.

3. Click on that newly created compression setting to open it in the Inspector window. Click the Encoder tab. Click the Video: (Settingsā€¦) button. Make the frame rate 29.97. Check the interlaced box. Set it's drop down menu to upper field first. Click OK.

4. Click the Frame Controls tab. Set Frame Controls to On. Set Output Fields to Bottom first. Leave Deinterlace on Fast. Leave Adaptive Details checked. Leave Rate Conversion set to Fast. Leave the Set Duration to: on 100% and make sure it's radio button is selected and NOT the "so source frames play at 29.97 fps" button.

5. Make changes to the Filters or Geometry sections as needed. Those settings listed above are the ones critical to getting the proper 3:2 pulldown added.

6. Submit the compression, then bring the resulting video back into Final Cut Pro. Place it in a 29.97 timeline and make sure you watch it on an NTSC monitor to verify that it looks good. If you step through it frame-by-frame you should see the familiar pattern of 2 split/interlaced frames followed by 3 whole frames. This is a very important step. I tried many solutions that looked OK playing back on the computer monitor, but looked terrible on the NTSC monitor.

Shane's notes in this thread have an inconsistency, just pointing out that for HD outputs, they should be UPPER (odd) field first. SD outputs are the only time you would use lower (even) field first.
