workflow for MPEG source files

My ATI All-in-Wonder card captuers footage [best] in MPEG format which as you all know is not the flavor V5 like to edit the most. What is the best workaround to get quality final output?

Has anyone had really good quality captures from this card, with what capturing prefrence.
Sceneylizer Live doesn't connect to the ATI card correctly.

Will I have to get a A/DV converter?

I think the answer to your last question is a resounding "YES!" if you want to do quality work. I've gotten some semi-decent captures from that card in uncompressed AVI, but at the cost of about 1.7GB/minute. If i needed a lot of time captured and wanted to keep it around to work on it for a while, i'd capture a few minutes' worth, then render that capture to DV, then capture a few more minutes and render to DV, etc. You could do the same thing with the MPEG captures, but i'd say it's rather pointless if you can capture uncompressed.

how to capture with that ati card to huffyuv or mjpeg ... better solution than mpeg or uncompressed for editing

I have an ATI AIW & used one before with DVCPro's (the captured file was beautiful, BTW). I used to use the mpeg capture too (all i frames, 8mbs, etc). untill... I found out that you can capture via the Huffy codec to AVI in a slightly off DV dimension and it STILL NTSC DVD compliant! :)

That's what I've been doing and it works great.

wow great news, thank this might work to get a Vegas system into play until I get the Decklink card and RAID drives.

[edit] I've got an audio sync issue when bringing HUFFY avi into Vegas. It plays fine in several players but audio needs to be brought down timeling to sync... hmmm

[edit 2] S this means I can take Beta SP machine thru analog in ATI All-in-Wonder 9800, capture at huge file sizes but in short 10 - 20 min chunks should be NP to render out, but PTT is limited to DV so project will get compressed... am I right?

I've never had a sync issue with the ATI (that's why I use it).

As for the DV thing, Huffy should be higher quality then DV (lossless). But, from your sources you shouldn't see a difference (Like I said in my other post: I've seen an ATI AIW capture DVCPro via S-Video cable and it looked just as good as the DVCPro. This was a TV show recorde via sattelite to DVCPro then capture on a computer to edit).
