I'm trying to encode my mjpg avi 352x576 pal to svcd. CCE accepts the file resolution so no need for frame serving. But I'm still only getting 0.5??? I have a PIII 1Ghz cpu win98se platform with over 300Mb ram. Any ideas what I'm doing wrong?? I tried a mainconcept DV file resized via avisynth and I still got 0.9 with CCE. What's wrong with the MJPG file. I thought it would use the hardware on the capture card to decompress. Shouldn't that make it faster??

I picked this resolution for an experiment so as to have nothing else in the chain other than the MJPG avi and cce.

Try using another software mjpeg codec like Pic Video (http://www.jpg.com/video/mjpeg.htm) or Morgan M-JPEG (http://www.morgan-multimedia.com)

The Pinnacle/Miro cards use hardware encoding, but still use software for decoding.

The Morgan codec is faster IMHO. I had the same prob with my card until I installed the Morgan codec. Not super fast, but faster than the Pinnacle one.

Yes, but how can I get the PICVideo MJPG codec to coexist with my DC30 codec??
Whilst writing this I thought of the following...

I was thinking of installing the PICVideo and then altering the FourCC MJPG references in system.ini and the registry to something like PJPG and then reinstalling the Pinnacle DC30+ drivers to cater for the MJPG. That way I could capture the footage and use a small utility to alter the avi's FourCC to PJPG so that I could then edit using PICVideo's codec. Then if I ever want to playback to tape I just need to alter the FourCC of the avi back to MJPG. Otherwise if I need to convert to MPEG I could leave it as PJPG as the PICVideo would be faster at decompressing.

What do you think? Could it work???
