Occasional combing on otherwise great 60i>60p (tdeint)

Hi guys
I've been out of the encoding loop for a year or two, and of course am not up to speed on current developments.

I have a video that is relatively simple, but has high motion in areas. I recall using a filter called tdeint a while ago which produced incredible results. It was pretty CPU heavy and it went at around 1 or 2 fps on a 2x2GHz Athlon TL at SD resolution (IIRC - there may have been some other filters adding to the complexity). I found the script on doom9.

Tried tdeint again but I'm now getting rendering framerates in double figures, so I'm obviously missing something. Quality is still excellent, but I'm wondering if there is anything better, or if anyone can point me in the direction of some of the more extreme tdeint scripts? I'm just using tdeint(mode=1) which is great, but in some of my encodes I noticed occasional combing that seems to have slipped through, or that tdent could not do anything with. If these are unrepairable, I think I would simply blend these trouble frames. This happens at around 64 and 63 seconds on the in game timer, as the character reels in the corner from getting hit while blocking low.

Here's a sample in case anyone feels like playing around. Encode time is not an issue, but quality is important. I've got a mountain of stuff on my DVD recorder, and I want to archive them in H.264 eventually and delete the vobs, so there will be no going back.

Here's a bonus clip of Forza Motorsport that was causing problems. I really only care that I can get good quality for the Street Fighter clip, but this one was giving tdeint problems.


Thanks in advance
