Narrowed down, ATI restriction, NEED HELP....LOL

[arcorob]

I have been pestering the other forums but have finally narrowd it down here. PLease, if yoi know about this, please help. Even if it is to tell me I need better hardware than ATI.

I have
ATI all in wonder 128 pro
P4 2.0 machine, 1 gig memory, fast and LARGe drives

I take Hi-8 camcorder and capture as AVI. Used VDUB, Premier , Video Factory, ATI, etc. I am trying to capture at 720 by 480 (or actually anything above 352 by 240). Produce in Video factory, use TMPG to make MPEG 2. Problem is MOTION blur. Now you have the target.

It captures FINE at 720 x 480 , very clear EXCEPT , the picture looks interlaced. Series of horizontal lines. When I convert or even play, this is what it does.

Still shot(lines represent the picture )

So you can see it would blur. I have tried different field orders, told it non-interlace, de-interlace and run dozens of experiments.

What I come up with is that at 352 by 240 or less, the picture defaults to progressive, non-interlace, and comes out fine. Converts fine. Anything above, automatically gets this issue. Larger is not necessarily worse. In other words 352 by 288 is equally as bad as 720 by 480.

I read here there is a problem with ATI but doesn't seem to apply to me because I CAN CAPTURE. Just not the way I want to. Is it because I am overextending what the ATI card can do ?

How do I produce a CLEAR non-interlace PROGESSIVE scan 720 by 480 AVI file with VDUB, Video factory, whatever with this setup... ???

THAT is the question. This seems hardware driven. Will a CANOPUS unit with firewire fix this, do I need other hardware, will radeon help ?

Thanks to all who really READ and HELP.

If you capture both fields ie > 240 you are capturing an interlaced stream and you should expect to get interlaced output.

This is a good thing(tm) once you know how to use that extra information to make your encoding even better.

Interlacing is a cheap bandwidth saving trick for broadcast purposes that dates from the first half of the last century. I suggest you capture mpeg 2, I frame only, 15 Mbps progressive (non-interlace) 720 by 480 with MMC 7.6. Reencode this capture with tmpgenc, cce or the mpeg 2 encoder of your choice and if you intend to playback the file on a computer monitor or lcd projector do not interlace when you encode it. I use Xmpeg 4.5 and reencode to Divx 5.02 for HTPC playback to a projector. I let the ATI card and MMC software deinterlace on the fly because its a bitch to do it properly via software ( see http://nickyguides.digital-digest.com/interlace-test.htm )

problem is I cant seem to get rid of it. All this INTERLACING seems to do is ADD BLURRED motion. I understand its purpose, what I dont understand is how ATI is intercepting EVERY capture and every CODEC i use above 352 by 240.

If I could take the INTERLACE and DE_INTERLACE and get rid of motion blur, I am sure it would be great, but nothing seems to work .

Can you give me some specs , say on TMPG on how to get rid of it ?

I will try to capture in MPEG 2 but it will NOT be lossless then.....What is a fella to do.

I think I am go for the Canopus ADCT - 100 with a firewire card. Something is inherantly wrond with ATI ..>Suggestions ???
