Ati Capture/proprietary Codec?
(Click here to view the original thread with full colors/images)

Here's a brain-twister for those with big brains! (especially ATI users).
I recently bought a used ATI All-in-Wonder 7200 (32meg) for this machine,with the sole purpose of video capture in mind (especially TV).I can't afford a good,fast 9200 yet .
MACHINE: FIC VIA CHIPSET MOTHERBOARD,AMD 1.1G ATHLON,256 PC-133 RAM,VIDEO- ATI ALL-IN-WONDER 7200 32MEG
O.S.: WINDOHS! MILLENIUM (Me = "M"ULTIPLE "e"RRORS)
Problems are:
1) I can't capture using "Div-x low","MS V3",etc. with decent results.It comes out with horrible pixelation (big as yer fist LOL),poor movement/framerate,etc.Horrible! I know this card is capable of using those avi codecs with GOOD resulting clean frame images,but it doesn't!! The card I replaced was even better (*8* meg all-in-wonder!!) Something has to be screwy with the software or something! Anyway I switched to MPEG-2 SVCD mode to capture instead.It works waaay better! Pretty smooth and clear.OK-I figure-so what about the avi modes,I'll just use mpeg-not the end of the world--problem wasn't solved,but at least I had a way around it:
Mpeg-2 with compressed audio.I'd just convert the larger mpeg-2 vid capture file to a quality avi later...
2) Didn't work that way.Video players won't even load/play the mpeg-2 file it made (Well-it WILL load and play on this machine,-but it takes a long time! I figure it's searching for the proprietary ATI playback codec/driver).I try to load it into "Virtual Dub" (favourite editor) to edit+convert to avi,and it says -"file packet length error",or something similiar. HUH? I have heard that ATI uses "Proprietary" video drivers/codecs. Looks like this may be true.It somehow uses *NON* standard mpeg (and possibly the reason for the cruddy avi codec captures) codec/method.I then tried another conversion utility.It wouldn't even LOAD it! I tried ANOTHER one.It loaded and converted it,but when I watched it,it was either skipping MASSIVE frames on playback,or it never did convert/encode all frames to begin with!! (Like watching a DVD movie on HIGH Fast-Forward shuttle speed!! ). 
SO please- if any ATI users know what the deal is with all this,or anyone knows a Conversion Util that will or may work (MPEG-->AVI),let me know!! It could be the extra ATI software+"Multimedia" pack that I installed (newest ones for it).Can I use/capture without the ATI multimedia installed? ATI users,clue me in please.In fact--ANY advice would be of help,THANKS!

I can give you some general advice...
Don't capture video using divx or xvid. The way they work best is in a 2 pass encode: 1 pass for analyzing the movie, another pass for encoding it. Capturing directly to divx/xvid skips pass 1, and gives you crappy results, since it doesn't know what compression/bitrate to use at what times.
The reason why your captured files don't play on other computers is probably because they don't have that same capture card installed. Capture cards tend to come with their own hardware dependent codecs. Normally, you capture using the hardware codec (at high as possible quality settings for maximum end quality), then afterwards you convert it to something more useful.
If your files don't work properly in virtualdub, either use a different codec to capture with, or convert it to something that virtualdub can handle (the program you're using to capture it should be able to do that). Converting it will degrade the quality somewhat though, unless you're gonna use uncompressed avi (which will fill up your hd faster than anything else  ).
