View Full Version : rendering as ...
6th June 2002, 03:55 PM
maybe you can help ?
I use Vegas Video to make VJ loops. I use PAL (d1) uncompresed AVIs. when the loop is ready I render full color AVI loop to file then when I play it in VJ soft I get.
in resolume everything is OK
in VJo R3 and Vjamm - result green instead of red color + red instead of blue ...
what is wrong ?

maybe the programms did not support to play uncompressed Video?

I shouldn't really be explaining this as my soft will be competing against VJo but ah well.
AVI file handlers might say they're 16 or 24 bit, but on the average they return 15 bit bitmaps. The end bits can get confused, and the way that VJo and VJAMM compute the clips could be messed up in some method and not as customizable. Because it assumes 16 bits instead of 15 bits, this could lead to an ending massive trouble. If you have an empty color bit per pixel, then eventually said pixels' color will wrap and delete a few pixels, in the meantime:
bbbbbgggggrrrrr (15 bit AVI) will become
bbbbbggggggrrrrr (16 bit AVI). Said 16 bit AVI will end up being formed out the next next combination so that:
Which means that the green's have the larger extra red quantities and the red's have the larger extra blue quantities. Bug Many... he might provide a patch.

can you make a very short avi (less than 2 meg) that has these faults and send it to me please
I'll have a look at it and see if i can replecate your bug
also could you tell me exactly what your vegas project settings are and what all of the output settings in vegas are

I use direct show to read AVI files, and I've the same problems
in elektronika (not 15 bit) but somes AVI sucks, the same as can't be read in vegas video (works only with krosoft media player)
to me, it's seem the new divX 5.xx video drivers sucks, and somes
do u have the same problem in u'r soft ??

But no, I'm thinking not. I'm thinking it's along the 15 bit line... and we've got separate bitmap classes, color conversions, etc for each. We're also using the AVI file functions themselves for AVI as they are notably faster. At present when we add MPEG we're either going to adapt an open source decompressor, parse to AVI (a la VirtualDub) or use DirectShow.
Have found that DivX 5.0 is a HUGE problem. I actually just spent about 6 hours this weekend reinstalling everything after DivX 5 fucked up DirectDraw (thus not allowing me to play videos in the earlier, cheaper version of my app). Am actually planning to disable DivX 5 export in SoftScan for just such a reason.
P.S. to yoy.... the topic on SoftScan is something bouncing around EyeCandy and here a lot... it's a software scan converter and I tested it on an old demo of Aestesis and it worked teriffic. Would love to try it on elektronika, but don't have a copy of it.

it sounds like an mci codec issue - VJamm uses the mci as does VJo where as resolume is a direct show app
what codec are you using?
try unchecking the box that says "create an openDML compatable avi"
if someone could send me a small test file with this error i'll be able to find out whats going on
