View Full Version : Looking for free lossy intraframe VfW codecs

I'm currently reworking a tutorial about capturing video SD-video from video game consoles with a cheap USB grabber and Virtualdub. In the first version I suggested using Lagarith as capturing codec, but people complained about huge files sizes so I'll try to find a lossy replacement for the updated tutorial.

My first idea was to switch to MJPEG, but curiously there are no free implementations left. The Cedocida DV Codec seems to be a good choice, but the author only provides sourcecode so I'd need to send the reader to some third party site that has a precompiled package.

Do you know of other alternatives for this scenario? Interframe codecs are out of the question, they lead to all kind of sync problems and can't be post-processed so nicely.

FFDshow's VFW encoder package includes an MJPEG encoder, among about 500 others.

I think that most lossy codecs(e.g. x264vfw, xvid, ...) with keyframe interval 1 will meet your demand.

Yeah, in a personal speed versus size test and of course decoding demands, the ffdshow MJPEG encoder stands out.
Fast, small and less decoding cpu cycles.
Have a look.
My favourite , also not lossy, is UTVideo. It's getting better all the time. Dropped Lagarith for it.

Thanks for your replies. The audience for the tutorial is absolute video noobs, so I'm a little hesitant to tell them to use FFDSHOW VFW. So much options to configure will make their heads explode. :D

IMO not 500 but maybe up to 5 now... (FFDShow was castrated few weeks ago)
