problems with conforming to 23.98
Hello,
I’m trying to conform my footage (was shot on 35mm film) to 23.98 so we can edit on FCP. But when we look at the conformed media on Final Cut it jitters, and the only way to resolve it is with the De-intelace filter which take rendering time. Is there a reason why it jitters? I’d appreciate the help!

yes I am conforming with cinema tools

Was the footage telecined to digibeta or D5, dubbed to DVCAM then captured? Were you given an ALE or flex file? Did you use this to make a batch list in FCP? Or was this telecined directly to DVCAM for a negative cut?
Just curious as to your workflow.

You should be using the “reverse telecine” tool, not the “conform” tool in Cinem Tools.

It was shot on 35, then telecined to beta and digitized to FCP on 29.97 frame rate. Then it was reversed telecined on cinema tools to 24p and also was conformed to 23.98. We cannot do reverse telecine to 23.98 in cinema tools. it only allows for real 24p and not the puuldown version. So right now we’re trying to figure out the best way to confrom it to 23.98 without getting this jitter. any advice?

You cannnot reverse telecine to 23.98 only to 24p. any other suggestions?

“You cannnot reverse telecine to 23.98 only to 24p. any other suggestions?”
Are you sure about that? The last two features I’ve cut were reversed telecined in Cinema Tools to 23.98 and worked perfectly.
Make sure you’re following the correct workflow. Are your FLEX files importing properly. Check the start frames to make sure they start on 00 or 05’s. Are the Beta tapes non-drop-frame? They should be. Make sure the device control in the FCP preset knows this. Double check the clips digitize on the 00 or 05 frame. Trash your Cinema Tools prefs and start from scratch assigning a default for the reverse telecine method.
If all else fails just use a capture card like the Aurora PipeStudio, AJA IO or AJA Kona LH or Kona2.Michael Alberts

So this is a batch capture of a finished edit?
Here’s a trick to get 29.97 with 3:2 footage into FCP as 23.98 media. Dupe a Capture Preset (like 10 bit uncompressed) and switch the frame rate to 23.98 fps. When you capture footage from Digi, make sure your IN frame is set to an A-Frame (typically on 0). When you digitize, it will automatically strip out the 3:2 frames and you’ll have nice 23.98 media (media timecode will retain it’s relationship to the 29.97 timecode on the digi). Sometimes it misses and you’ll have jitters – have to retry it again, and it seems to work best in high-end machines with PCI video cards vs. an Io.

As Michael points out, you CAN rev telecine to 23.98fps. If you can’t, check your settings. You can always just rev telecine to 24.00fps and then conform to 23.98fps too if need be, but you shouldn’t have to do that.

Cinema tools reverse telecines to 23.98 and 24. Instead… do one reverse telecine with your footage parked on an A frame. Play only that clip back in your timeline… perhaps change the standard upper lower radio button as well..but just do test before you commit to doing them all.
Maybe the preferences are corrupt in cinema tools if you can’t choose 23.98.
