codecs

[Enrico Ng]

I have a couple hours of video I have to edit. I can edit it fine if the video is captured in divx, or uncompressed. The problem is that when I capture in divx, it looks really crappy. I have to capture uncompressed first then make it divx.
This is all on a different computer.
On my computer, I just use MJPEG then make it into divx, the problem is that my other computer doesnt have a matrox card and no MJPEG. is there any good MJPEG codec I can download for free that works well? or any other solution. I dont want uncompressed frames because its just too big.

PicVideo MJPeg is made to order.

1t can deliver very good quality both during captures and rendering and is free. Just make sure you register it so you get the codes that remvove the logo from its output.

When you set it up to quality=20 it provides about 5 mb/s MJPeg. This setting works nice.

To capture with it use the 1.52 video drivers, Flying Dutchmans YUY2 hack, AVI_IO and use PICVideo MJPeg as the compression.

The procedure is very similar to how one does HuffYUV captures, but just using a different codec.

How does this codec compare to the Matorx MJPEG codec?

It won't play out the BOB on the G200 Marvel, but the G450 DVDmax playback feature works nicely with it. Marvel captured DMB1 MJPEGs can be played back with it in systems without a Marvel so its IMHO, on the must download list.

I tried the codec and it seemed to work.
but when I had it capture for a long time(10min) I would get a fatal error after a few min or the computer would freeze

[Dr Mordrid]

Sounds like you hit the file size limit in FAT32. Use AVI_IO to capture segmented files (*.00.avi, *.01.avi etc.) and you can fill the drive with video. You can even span a single capture over several drives.

this happened while using AVI_IO.
the first time I got the fatal error was after 10min
the second time it froze after 2min

[Dr Mordrid]

Did you watch the buffers while the capture was running? How high did they go when it failed?

Also you might have to check the Matrox YUY2 force keyflags box in the AVI_IO capture settings menu. I don't need this on a G400's but on a G200....

As I mentioned in my orig. message, I am capturing on a different computer without a matrox card. that is the whole reason I am using a different codec, otherwise I would just use the hardware mjpeg.

the buffers stay at around 1.
after it says fatal error, it says 50

also I am capturing RGB because the card doesnt support yuy
