Green frames after Cinema Tools reverse telecine with ProResHQ

[Jeremy Garchow]

Have you tried the Rev telecine feature in Compressor3?

[Ted Griffis]

Hi Jeremy,

Yes, I have tried Compressor and though it does not introduce green frames its results are lack-luster. Cinema Tools is much cleaner in removing the pulldown, albeit when it doesn’t add green frames.

After running through compressor with the same “in” point in the clip (the “A” frame) the resulting 23.98 file has visible interlaced lines whereas the ones from a “successful” trip through Cinema tools do not.

If you have any suggestions on making compressor work correctly for this workflow, I’m all ears as compressor might be a faster engine anyway with an 8 core, just doesn’t seem to have the same flexibility in the settings to achieve the right result.

Thanks for your help,
Ted

THere is a reverse telecine feature in Compressor and you don’t have to choose an A frame. As long as you don’t have any cadence breaks, you should be fine.

You can find it in the frame controls tab under deinterlace. Every time I have used it, it’s been spot on and you can do everything in a batch.

Yup, that the setting I’ve been trying. So does compressor analyze and find the right frames on its own?I’ll keep doing some more testing with compressor but still a bit confused as to why Cinema Tools would produce Green frames. Hmmm.

Oh by the way, here’s a more detailed config:
OSX 10.5.2 FCP Studio 2, Compressor 3.0.3, QT 7.4.5, Cinema Tools 4.0.1

Thanks,
Ted

Yes. No A frame searching necessary.

Hmmm is right.

I get bright green artifacts (usually big rectangles on one side of the frame) when I have embedded Motion clips in the timeline.

For example – if I send a clip to Motion to stabilize it, then render in FCP (in a ProResHQ, 1080p 23.98 timeline) I get green stuff. Every time. So I have to export a QT file from Motion and import that into FCP. It’s a pain.

Details:
10.5.3, FCS 2, 2×3.2Ghz Quad-core MacPro, Kona 3

I have had issues with Motion Projects rendering as solid green clips in my timeline. This has happened with ProRes 422. I have not tested this with other Codecs.

It was driving me crazy though trying to fix it. Was never able to resolve it.

[Ted Griffis] “So it seems that only the QT ProResHQ file generated from the ioHD creates a problem in cinema tools. Has anyone else encountered this green frame issue in cinema tools with ProResHQ or any other format? “

Yeah, and my testing indicated that it was a ProRes issue, I did the same thing you did and I was unable to remove the pulldown from any file I tried in the ProResHQ codec. I have had differing results in the SQ versions. Live captures seem to be OK for Pulldown removal, but software conversions show the same green results.

still testing however, One file I used was from a sony EX1 and the cadence was not 3:2 but 2:2:2:4, and CT does not remove that cadence very well at all.

What Camera is the footage from and Exactly how did you handle it.

Start at the source – like I said in my post -one of my issues was camera specific.

Thanks for the input Gary.

[gary adcock] “What Camera is the footage from and Exactly how did you handle it. “

Well actually it was not from a Camera. The footage was a Digibeta telecine of a film from the Nation Archives. I captured it via SDI from a Sony J-30 into the ioHD as 1080 29.97 (Zoom Wide).

The odd thing is that the only the original ProResHQ file(s) cause the problem (anything captured directly from ioHD), though an exported section of that file(s) still in ProResHQ works flawlessly when run through CT.

Does it sound like time to move this to ioHD forum?

Thanks
Ted
