View Full Version : codec problem with pic-mjpeg
6th October 2002, 03:52 AM
my problem: i use the pic codec of pegasus cause of its speed. now i ran into a prob rendering videos bigger then about 4700 frames - at this framenumber i could twice reproduce a full system destruction:
vmm32.vxd & vmm32-subdir missing = windows dead / had to be re-installed!
i am running vegas on win98se duron 800mhz 126mb system
do i have to stick to small size video snippets or can a different codec help (like morgan or leadtools)?
has someone done any benchmarking on mjpeg codecs i didnt find a serious page..
thx in advance;)

I too use the PicVideo MJPEG format because of its small size, good quality, and fast performance. I have not run into the issue you speak of. Could it be the 2GB limit of the original AVI format? Doesn't seem like 4700 frames would occupy 2GB though. Does the problem only occur when rendering with Vegas Video 3? I just tired to render 5000 Frames with VV3 and had no problem.
I use Windows 2000, and I do recommend that you upgrade to 2000 or XP. 98 & ME are outdated, they crash often and don't protect application memory.
Let me know what happened after you reinstalled your OS...

thx for ur fast response:)
the bloody history:
first crash with vegas 3.0a at frame 3491
- rebuild vmm.vxd manually -> windows ok
update to vegas 3.0c build 138
crash again with mentioned destruction at frame ~3491 !!
- re-installed system from scratch:
win98se/ger, dx 8.1b/ger, vegas3, capturecard miro with bt-chip, fast movie processor 1.44
fmp also crashes at about this frame#, but the system stays in function:p
@ the moment i can not effort killing win a another time..
yes - i had xp on the machine -after cutting out all un-needed stuff it was slower than win98.. i have no money for more ram / a better graphics card etc.
actually i want to change mjpeg codec now (for longer pieces).
ps: my format is allways 640*480, 4:1:1, 80% (~?) quality = nice

Wondergirl, I tried rendering with VV3 with the same settings you specified, with no problems. I wish I could be more help here, but I think there are too many variables for me to be of much help. If I think of anything I will let you know...

hi burstingfist, thx for ur help.
so it is probably something in the guts of my win98..
i hate NOT to know what, but -u are right in this- it is an obsolete system & i dont want spend too much time on it.
i make a new thread about codecs, yes;) :p
