Mjpeg

[sergiovalentino]

I'm using this combo:
Win 2000
Marvel G400
Drivers: 5.20.016
Vtools: 2.02.017
This, works very, very fine with Morgan codec, by quality and speed, with user fourcc dmb1 and support interleave unchecked, also in Premiere.
Morgan is much better then Matrox faulty codec, that not work at all in Premiere (a good stuff for Matrox programmers).
However the question is: is there a better too mjpeg codec than Morgan?

Have you tried PicVideo yet?
I don't know the Morgan codec and thus can't compare the two, but I'm quite happy with PicVideos FREE mjpeg codec. Very configurable, from good compression to very HQ captures and not too CPU hungry.

Actually PICVideo isn't free anymore. It's $18 USD now. That said it's still an excellent soft MJPeg and VERY fast. Full frame high datarate captures can be done on even moderately fast systems.

I can say too that the PicVideo is excellent and is worth the $18 it costs. Without the YUY2 patch and a good codec, the Marvel is not worth much, the Matrox Mjpeg codec is of regular quality in its best setting, and you can't do anything with it except watching the videos you captured, because you can't use for editing in an NLE, or sometimes you can use it but it's horribly slow. To me the best choice is the YUY2 patch with PicVideo, which is an excellent codec. Capturing with the HuffYUV codec has very good results too, but the captured movie can't be played back smoothly, the PicVideo movie can be played back perfectly.

Hi, i'm very interested in this argument, because i try many solutions realizing that using Huffyuv i work very well when i compress in mpeg1 or mpeg4, id est i can use low bitrate and have clean movies, spending less time than Matrox MJPEG; the only negative point about Huffyuv is that it needs very very large and quick disks for full capturing; What about Picvideo? It's similar to Huffyuv or to Mjpeg?

Thank, from Bologna,Italy

i make my mjpegs into divx. i used the picvideo with my all in wonder and the qual wasnt as good as with my current mjpeg caps.

also, i couldnt edit them. i could play the clip, but had a decompress error when i opened them in vdub. i dont have that problem now though. weird.

would capping with the software picvideo be better than with the hardware matrox one?

Matrox MJPEG codec is not faulty, it works fine and gives better quality than any software codec.

[Dr Mordrid]

1. not faulty, but low on data rate at just 3.x mb/s.

2. PICVideo can do much more than this and deliver much better quality on a per/mbps basis.

3. high data rate MJPeg is better for encoding to MPEG's for those who don't want to or cannot use HuffYUV.

4. It's tremendously fast. Faster than some hardware codecs.

i'm confused, do you use the morgan/picvideo to capture in hardware instead of the matrox one, or to cap through software? i use the matrox one and i have no problem with the quality. i used to cap to huffyuv with my aiw but the qual wasnt as good, plus it was 15-20 GB for an hour, whereas my mjpeg caps are 3-4GB per hour and the qual is superb.

would i get better captures yet by capping with huffyuv with this card? i chose huff for the aiw as it gave better qual caps than by using mpeg-2.

HuffYUV is a transitional lossless codec primarily used to prepare video for MPEG encoding. It's not really a viewing system at all. IF you aren't going to encode to MPEG then PICVideo's software encoder can be used with great results.
