video captured by ATI AIW Radion to VCD/Athalon 1GHz.

[zap91284]

Anyone here know how long it would take to convert half an hour of video from what is saved by ATI All-in-Wonder Radeon using a system to VCD and/or SVCD video using a computer with these specs:
Athalon 1 GHz cpu
256 mb of RAM (Not sure what type, but nothin fancy like DDR)
7200 RPM hardrive
320x240 or 640x480 resolution video (or whatever the norm is for this kind of stuff).

for VCD you can almost burn it instantly, but the quality isn't great. it gets real blocky and has lots of high-frequency noise. there's a VCD preset in MMC 7.1. 'edit' it and turn motion estimation up to 100%.

for 480x480 svcd, figure about an hour all told:
-capture 480x480 2.3Mbit VBR MPEG-2
-run through 'fix12c.exe' utility to fix display problems on some dvd players(esp if you have a
pioneer player)
-demux and remux to SuperVCD VBR using TMPG 12f or later
-burn

Sorry to barge in but what problems does the fix program you mentioned fix?

Just curious, wouldn't you get better quality by capturing 480x480 Mpeg-2 I frame only at let's say 6Mb/sec? This way you could do frame accurate editing before you encode it to SVCD.

I've had excellent results capturing to 640x480 at 6mb/s with my ATI AIW Radeon.

After capturing I use premiere and the panasonic plugin to edit out commercials and encode.

I'm experimenting with capturing at 480x480 at 6mb/s. Video should be even cleaner and there will be no need to resize if I want to encode to svcd.

true, but when doing VHS->SVCD or DVD->SVCD i don't have much need for frame accurate editing, though i wish i had a program to do it anyway... and doing what i said doesn't require any encoding step, just a demux/mux. and the quality is very good, rivals what you'd get out of encoding an I-frame 6Mbps in TMPG. you get different artifacts- JPEG mosquitos instead of blockiness, which disappear to the eyes at a shorter distance from the TV, so in my opinion it's preferable to do it this way.

the fix12c program corrects improper SDE display tags in the MPEG headers. basically, if you have a player that reads this info (pioneer seems to be the main one) they will think the video should be 480x540, and when they scale it to fit the screen, it comes up the right width but about 10% too tall vertically. you can fix this in your TMPG templates by editing them as a text file and changing these lines:
MPEG.Display.Height=480
MPEG.Display.Width=480

ATI and dazzle just messed it up with no way for users to change it, so someone wrote a program to parse the movies and fix them w/o reencode. it takes no more than 4-7 minutes on 60 min video for me. if you've ever had the videos vertically stretched or seen the 2/3-1/3 problem where the video shows squished on part of the screen and agan real small in the upper right corner, this might be the answer. just search the forums, i explained this quite a few times.

the short way. in the run bar:
fix12c "D:\myfile.mpg" -v 480 -h 480

Thanx for the replys. My next question was about how to get the best quality anyways.

I just picked up an (S)VCD capable DVD player so I haven't got the process perfected yet, but I've had good luck so far using the ATI AIW tools found in the Tools section on the left menu. They let you tweak the ATI MMC VCD settings to increase the bitrate, and thereby get a better looking VCD. For SVCD, I still need to demux/remux with TMPGEnc, but at least I can capture directly from the AIW and not have to re-capture to SVCD compliant MPEG-2.
