Properly Converting 23.98 to 29.97...PLEASE HELP!

Hello All,

My situation is this - I shot a project on two different formats. The interviews, which is the majority of the project, were shot at 29.97 with the DVX 100A. The cut aways/visuals were shot at 23.98 with the HVX 200.

The project is finishing in standard def and will most likely just go to DVD. What is the proper way to convert the 23.98 footage to 29.97? If I use Compressor to convert the clips then it takes HOURS to convert. Is there pull-down I can apply or something like that so I can edit all in the same frame rate? I'm running Final Cut version 5.1.4...if that helps.

Thank you in advance for your comments and help!

Set up a custom Compressor preset for progressive mpeg2 at 23.98 for DVD -

Some advantages:

20% fewer frames to encode means 20% lighter compression with the sam average bit rate and file size.

You don't need to convert your sequences beforehand

The resulting DVD will be compatible with progressive playback, and the player will add pulldown for interlaced playback.

Hi Max,

Thanks for the input. The problem is that I need to convert the footage so I can edit both 23.98 and 29.97 in the same timeline. The 23.98 footage speeds up about 30% when played in a 29.97 timeline and I have to re-render everything everytime a make a tiny change.

Does anyone ever do this...edit both 29.97 and 23.98 footage together? Surely they must and there has to be a work around. Please help!!!

Thanks,
kristin

Kristin,
The process that you want is adding in a 3:2 pulldown. If you just drop in the 23.98 footage into the 29.97 sequence, FinalCut will just duplicate frames and not properly combine them. Unfortunately, there are only 2 ways of adding in the pulldown that I know of. One is to use After Effects. The price tag is pretty hefty, though, and if that is all you are going to use it for, not really worth it. The other way is to set up a 23.98 sequence, but your 23.98 footage in it and lay it off to a tape that's formatted at 29.97. FinalCut will properly add in the pulldown when playing it out. (Go to System Settings - Playback Control and make sure the pulldown pattern is set to 2:3:2:3.
Capture the material back in at 29.97 and you are good to go.

Good luck.

If you want to add the 3:2 properly, do not use Cinema Tools. Properly added, the 3:2 process for some of the frames takes a field from one frame and a field from another frame to make a completely new frame. It is not, definitely not, a process of just duplicating frames. From what I know, Conform in Cinema Tools simply speeds up (or slows down) the footage.

Hi Leigh,

I have After Effects and use it often for motion graphics but at this point all the footage is at 29.97. How do you add the 3:2 pulldown in AE?

Also, if I were to print the footage back to tape and then recapture it - wouldn't I be losing a bit of quality there? Which way would you suggest for maintaining the highest quality?

Thanks for your help!

For After Effects, put your footage into a 23.98 comp. When you make the movie, under Render settings, change Field Render to Lower Field First then change the Pulldown to WSSWW. This will change the footage to 29.97. I'm not too sure about any quality loss if you go to tape. You might want to do a test. Using AE, depending on your footage, it could take some time to render.
