Mjpeg

[Bimminger]

On my PIII 600MHz, I'm encoding .avi Matrox MJPEG video files (using the old matrox rainbow runner studio, windows 98). now I want to play these .avi files on my win2000 notebook - where to get the matrox mjpeg codec?? is it availabe as a software codec or does it only work on the pc that contains the hardware?

thx, CB

Try a SW codec for the laptop. Either PicVideo or Morgan should do the trick.

The reason is that the G400 uses HW compression and your laptop needs to have a SW codec.

i tried the PicVideo codec - but the media player returns the error

"Es konnten keine Filter zum Rendern der Eingangsdaten gefunden werden. (Fehler=80040218)"

[translated into English by myself: 'no filters found to render the inputstream']

if i wanna play my movie on the notebook... (on the 600MHz PC it works...) and because of this output i thought there's a problem with the codec...

please, help me. thx, CB

Hi,

Sorry if this is a simplistic answer, but make sure that the "codec enabled" property of PIC MJPEG is turned on.

Actually Matrox drivers do come with a S/W codec , but the fastest way to swap decompression codec
is to change the fourCC code in the AVI file from "dmb1"(matrox) to "mjpg"(3rd party S/W codec)

Now what happen if you want to upgrade to a G450 tv from a G400 tv ?
The PICvideo codec decompress to a higher brightness level so its not an ideal replacement , the matox S/W decompression
looks sharper too, all although it is slower at decompression than PICvideo .
Could someone look at their G450TV CD that came with the card to see if there's a utility to decompress
video that you captured with G400 .

the picvideo codec appears as a "lossless JPEG codec" - not as a "MJPEC codec" - is it the same?

and how to enable the codec as andrew said? where can i find this checkbox???

thx, CB

Hi,

it seems as if you have installed the wrong codec. They
offer three in a package. Please install the MJPEG codec.

You will find the mentioned checkbox in the properties
of the codec.

I recently downloaded Morgan, PIC Video and Lead MJPEG codecs to handle Marvel MJPEG hardware-generated files on a computer without Marvel.

Morgan totally upset the whole computer and didn't work properly, so I removed all traces of it. I could detect almost zero difference between the other two, both of which seemed fine, both for 'co' and 'dec'. I've left both on the computer (after payment), so I have a choice, but I've yet to see anything where one is significantly better than the other.

Somewhat OT to this thread, but I offer it for what it's worth, I've also done a comparison between TMPGEC and the MSP 6.5 DVD plug-in for generating the SVCD-compatible 480x576 PAL MPEG-2 files. Using the default settings for each, the Tsunami produced a much smaller file but had more artifacts visible. However, these could be reduced to roughly equal proportions (but slightly different in nature), by tweaking the settings, but the file size went up to about the same as the U-Lead. Burning the SVCDs with both the mini-artifact files (using the DVD plug-in for the MSP version and Nero for the Tsunami) produced zero perceptible difference on a stand-alone DVD player feeding into a reasonable quality 29" consumer TV (consensus of 6 family members). In view of this and the better "user-friendliness" of the U-Lead, including a better menu format and lead-in, I propose sticking with it. I do have one reservation about the MSP DVD Plug-in, though: I've been plagued with it freezing the computer solid during the image file creation, although I can get round it by a rather PITA procedure.
