Reverse Telecine Doesn’t Work for Digibeta but Does for DVCam Clones
I posted a big thing here and no one responded:
https://forums.creativecow.net/thread/8/1135295Reverse Telecine is going great for SD clips, but it will not work for DigiBeta clips. It works great on the DVCam clones (of the DB) but I get all sorts of interlacing issues during movement if I try to RT the DigiBeta clips. I can even downconvert DB to DV in Compressor, then do my reverse telecine on that file and it works.
It seems other people on the internet have had trouble with DigiBeta reverse telecining correctly, but I haven’t found a reason why or the solution.
Anyone have any thoughts?
FYI, I don’t have Flex Files or ALE for the DB’s or DVCam’s
Thanks,

How are you trying to remove the pulldown? Cinema Tools or Compressor?
DV and Digibeta footage both use different field orders, so it is possible that whatever program you are using is not guessing the field order of the digibeta stuff correctly.
There is another recent post about someone with similar problems:

Not totally the same situation, but worth a read for some of Jeremy’s tips. Sometimes I’ve found with problem footage you just need to try every possible combination of settings in Cinema Tools. The frame that you park the viewer on in Cinema Tools is important too, since that determines the start of the cadence pattern detection. The CT manual is worth a read too, if you haven’t already.
Hope this helps,

I used reverse telecine in Compressor. I was under the impression that DB & DV were both lower field first, though I’m not sure how that comes in to play here. I bring the file into Compressor and select reverse telecine and it greys out the options for Output Fields.
Any other thoughts?

[Christian Clark] “I bring the file into Compressor and select reverse telecine and it greys out the options for Output Fields.”
It greys it out because the OUTPUT format is progressive, so no fields. The issue at hand here is how Compressor interprets your footage on INPUT. Click on the thumbnail for your video file in the batch window and check the “field order” in the video properties window. Make sure it is correctly set to “upper field first,” then try again. If it still doesn’t work, you might have to use Cinema Tools, which has more advance pulldown cadence options. The Cinema Tools manual isn’t bad, IIRC.

This works! For some reason, Compressor was interpreting the DB files as LFF when they should be UFF. Once I make the change, reverse telecine works.
Any clue why Compressor doesn’t just see the file as it actually is?
Thanks again for your help!

No problem, glad it worked! Compressor doesn’t seem to be very good at correctly interpreting field order. I’ve never been able to get it to behave consistently. Nor can I figure out why it works in some cases, but not in others. So my recommendation is to always double check the clip properties before running a conversion.
