TIVTC artifacts

[SubOne]

I am trying to do a 24p pulldown on AVCHD content, which is basically 18 progressive frames and 12 interlaced in a 60i container. I am using TIVTC, and it works fine. However, there are significant artifacts - mostly combing present. I have also tried telecide, decimate. So far TIVTC has yielded the least artifacts. I will try and attach a screengrab, but I am sure you know what I am talking about. Any help will be greatly appreciated, thanks. :)

Screengrabs are useless. Post a link to an unprocessed source stream sample. Use DGSplit and upload to mediafire.com.

Thanks for the advise. The video I am trying to pulldown is very large, but I have captured an alternate video which does enough to display my problems.

You can find 2 files in the TIVTC.RAR file: http://www.storage.to/get/bHG7HRgf/TIVTC1.rar. (Mediafire doesn't seem to be working; this is where I had originally uploaded: http://www.mediafire.com/?sharekey=be4f9ccacb27978b0f83d91f6dff7c38488c0fa146c864dec95965eaa7bc68bc)

00009.MTS is the original, untouched, MTS source.
TIVTCd.avi is the output after TIVTC processing. There are clear block artifacts, and combing artifacts if you look closely. It is obviously not there in every frame, as 67% frames are progressive outright, and there's no scope for artifacts there. The script I used is simply:

TFM(slow=2,PP=7)
TDecimate()

All other combinations seem to render identical or worse results, and TIVTC works better than Telecide, decimate.

If it helps, these artifacts tend to be present more on moving video, so it may be a motion issue. Thanks for the help.

I think the problem is a case of garbage in = garbage out. That has got to be some of the worst looking footage I've ever seen. What seems to have happened is that MPEG crap has destroyed the interlacing pattern so you get stray combs. Try adding a Vinverse() after TFM (and maybe use pp=5).

Thanks for your help. The actual footage I am processing is different. After some experimentation, I think TFM with PP=0 and Vinverse() works the best. There are still artifacts left behind, though. I have noticed that there are no artifacts in the segments of the video where the camera is still. But when the camera begins moving, and the subject too, the artifacts pop up. I will try to put up the original source clip, but it's nearly 500MB.
