New Matrox drivers

[Raycaster]

The new matrox drivers don't seem to use MJPEG...

Using the new YUV (Ithink) its about 20m/s for 702X480 to capture back out for DVD use.

I'm droping a few more frames than usual because of the HD stuff I guess but is it worth to go back to the old drivers? I know the MJPEG at 702X480 was like 3.5Mb/s and was low on frame drops. This forum educated me to the fact that it was probably the tape fault of lost frames.

The question is.. Should I go back to the MJPEG or is there a quality difference to stick to the 20mb/s codec?

The new drivers are finally out, eh? Matrox said they were putting a stop to trying to make Drivers for a card which was made for Windows 9x work in ME/2K... So now you have to wait for XP to come out, or downgrade OS to get stable MJPEG captures. I personally just use YUY2 and then PICVideo 2.0, which is great.

Good advice.

Yes, 702x480 would produce about 20 MB/sec with any YUV 4:2:2 format. Use a capture codec like PicVideo to reduce the stress on your hard drive. Huffyuv is another good choice. (Click the Tools link at left.)

If you choose to keep capturing uncompressed video at 702x480, look for a YUV 4:1:1 format like Y41P or CLJR. This will reduce your video to 15 MB/sec without a loss in quality. (At 702 pixels per line, YUV 4:2:2 captures twice as much color detail as the signal could possibly hold.)
