IVTC Sex and the City

[Coentjo]

I'm having problems with properly de-interlacing epsiodes from Sex and the City (Region 1). All epsiodes are FILM/NTSC and Progressive/Interlaced mixed sources.

I've tried the GreedyHMA and InverseTelecine plugins for Avisynth (and TMPEGEnc as encoder). Unfortunatelly there are missing frames in the output file resulting in a choppy playback.

Is there anybody who has done a proper DVD -> SVCD conversion of Sex and the City episodes?

You might try GreedyHMA(1,0,4,0,0,0,0,0)

This will make it automatically choose between IVTC & deinterlace. The dropped frames will each possibly cause a high weave frame that should then get deinterlaced.

For some strange reason using GreedyHMA doesn't like my WinXP installation. The use of GreedyHMA results in a crashes within a couple of minutes 8-(

[trbarry]

Thats very strange. GreedyHMA doesn't have any operating system calls in it. But it will crash (immediately) if you don't have a machine that supports SSE. There is no error checking code for that yet but you need at least a P3, Athlon, Duron, or about a 550 mhz Celeron. Is that it?

But I think one version of DivX 4.11 had an issue with some AMD processors. Does it work without Greedy?

Since my PC has a 1.4Ghz Athlon the crash can't be related to that. DivX 4.11 is installed so for my next "expirement" I will uninstall DivX 4.11

Coentjo, the problem your having is casued by your processor. Unless you have a Athlon XP, MP or a 1GHz+ Duron you processor does not support SSE.

[Coentjo]

Correct me if I'm wrong Diable but I was thinking that the Athlon is supporting SSE but not SSE2?

[Doom9]

wrong... athlons support 3dnow, athlon xp/mp and durons at 1+ghz support 3dnow and SSE. SSE is also supported in all P3s, P4s (which support SSE2 as well) and Celerons starting at 600mhz.
divx4.1x doesn't require sse.. it works with mmx unless you have a p4 in which case it uses sse2 optimizations (and make no mistake no amd chip on the market has that kind of optimization... the hammer will but it's only due in like 12 months)

[trbarry]

GreedyHMA only needs the integer SSE instructions so it will run on all Athlons as far as I know.

Has anybody, either successfully or unsuccessfully, used GreedyHMA on a Athlon TBird?

On my system using GreedyHMA results in a crash (within a minute). Unfortunatelly after a couple of crashes WinXP got so "confused" (window with the message: Windows has recovered from a serious error) that I had to reinstall WinXP

Hi-

Has anybody, either successfully or unsuccessfully, used GreedyHMA on a Athlon TBird?

Yes, successfully, but with Win 98. No crashes, ever. But I haven't worked with Sex In The City. DivX 4.11 is also installed.

[trbarry]

I do have one HDTV capture with some garbage breakups in it that will cause an IO error about one minute into it every time. I'm looking at that one as it occurs only when GreedyHMA is doing IVTC, that is Pulldown modes 3-5. It doesn't happen using Pulldown types of 0-2.

I suspect this has something to do with the random seeking that occurs in the IVTC modes. Usually these random reads should be fullfilled from the internal cache Avisynth holds anyways but something else may be happening here.

But it might be an interesting experiment to try a third parm of 1 if you still dare run Greedy at all on your machine.

I will do some expiriments on my other PC (which is a bit slower 1.1Ghz Athlon TBird). A crash of that PC is no problem
