i am helping a friend of mine put some video up on a website. the video was provided to her by her client on a dvd. the eventual goal is to embed a flash video on the site. i could use megui to encode it into x.264 or xvid then to flash but that seamed redundant and i figured that it would reduce the quality. what i wanted was an uncompressed avi. they come out to about 11 and 30 gb for each vid. if there is a better way to go about this im all ears. so i rip the dvd with dvd fab 5. then open the vob's with dgindex and save the project to get a d2v. i used megui's avs script creator to write a script then open the script with virturaldubmod 1.5.10.2. i add the audio then file save as avi. full processing. here is the thing. the avi it kicks out when opened with vlc has bad color, it looks like it is a film negative or something and the audio works. if opened with quicktime or windows media player. the video color is correct and there is no audio. if i try to encode the avi with flash encoder cs3 the color is fine but no audio. ive been playing with adobe media encoder cs4 today but it seams to lock up and it stops responding. im running xp64 3ghz dual core and 8gb of ram. here is a screenshot if vlc and vdubmod. apparently when you print screen windows media player doesnt show up. disregard that the file says yuv i tried a few different things and they all did that

This looks like U and V channels are swapped! In Avidemux (http://forum.doom9.org/showthread.php?t=126164) you can fix this easily with the "Colors -> Swap U and V" filter.

Not sure about VirtualDub, but you could use SwapUV() in Avisynth and then feed the result into VirtualDub...

Rather it's just VLC issue with uncompressed video.

@fastbuck ink
Maybe just use some lossless codec - huffyuv or similar.
