Impossible clips (both telcined film and true interlaced video mixed)

I have some clips of a TV show that I capped. Part of the show is telcined film and part is true 29.97fps interlaced video (meaning an IVTC doesn't work). Essentially one of the cameras was film while the rest were video. So the style of footage changes pretty frequently. According to decomb I should use Telcide() and decimate(mode=1). That makes the stuff shot on film look fine, but the stuff shot on video that is truely interlaced looks a little iffy. I've tried every trick I know and I would rather not do a "blend" on the whole clip. What other options do I have? Stereodude

There's no need to do it with scripting. Decomb's manual control is easier. For example, to pass through untouched a section of interlaced video, you can use this override file: 200,750 c 200,750 - That would totally pass through frames 200 through 750. To leave the original field matches but apply deinterlacing: 200,750 c 200,750 + But anyway, you are always throwing away a field. What is the point of applying Telecide? Throwing away a field is guaranteed to decomb anything. :)

Here's an example of what I'm talking about. The difference in the two frames was a metric of .20% There are frames that are really identical in the telcined portion of the video that have a higher metric, so I can't fix the issue with the threshold. These are all the same 3 frame numbers (2003, 2004, 2005) [Sorry, you'll have to click the links. I didn't know image tags didn't work when I wrote the post.] "Raw" footage Footage after telecide and decimate End footage (from RAW) after discard 2nd field, and resize (blown up 200%) End footage (from telecide and decimate) after resize (blown up 200%) You should be able to see the blending in the one that has been run through telecide and decimate. Look specifically at her eyes and the area around the drummer's drum stick. In some scenes the blending causes is far more pronouced (I'll try to find an example and it causes motion to look jerky at times. It also looks a little odd when you get slightly blurier frames every so often. Stereodude

OK, I see now. Thank you for the data. I am working in this area right now and your report is valuable to me. But still, aren't you throwing away the even fields? If so, why bother with Telecide?

Neuron2, You're welcome. I take your earlier comment to mean that I could handle this video differently as well? I could do a decimate mode=0 and then use ConvertFPS() to change the interlaced portion to 23.976fps? I think that might cause problems where I switch "methods" in the script though. What do you think? Stereodude

I have just put a version of Decomb here that might help you: It will allow you to avoid getting the blends on your video segments. Please advise if this helps your situation. Just set guide=1 and be sure that Decimate immediately follows Telecide in the script.

I'm attaching the 12-17 build.

Don, Is this what you meant? Code:

Your link is broken so I have no idea what your current problem is. What I gave you is controlled by Telecide's decision about whether a frame is part of a 3:2 sequence (film) or is not (video). Regions believed to be video will not get the blending of Decimate(mode=1), regardless of its threshold. This should greatly improve the situation regarding your original complaint, which was that video sections were being blended by Decimate(mode=1). You won't need an overrides file; it will be done automatically. If you are reporting a different problem now, please explain it clearly in text, or directly attach your jpegs. Thank you.
