hi. i know that joreg prefers avi raw, but really that would be great to fix somewhere the idea of FULL HD video playing . m2ts sounds like a good format, I used it on classical diffusion.
but with vvvv many little troubles occures, like setting topowerstretched to get color, ect etc…
so my question is, for HD video diffusion and compositing with vvvv, will there be a special HD format that vvvv team may choose, that is supported in rendering by following editing apps:
because HD is heavy, i m not imaging one minute at all to use it in raw for HD diffusion;-)
oups… so i made a misunderstanding from a previous old mail.
have you got any link to this mjpeg picvideo ?
and wich codec do you think is the better to work in HD in direct ( blending, fx, not spreading) ? yours ;-)
working in a theatre does not cancel out the use of flash video, what makes you think that ?
if you don’t need to shuttle the video and just want brilliant playback, flash is a cool option. it uses all 4 cpu’s if you have a quad core. and you don’t have any problems with sync to frame issue. flash is doing its own thing and vvvv runs fine with 60 fps.
i actually use it right now to get some videos up and running on a crappy mini mac. :)
I’d also love to see a tech demo of flash playback. I tried it myself but must have done something wrong because it was incredibly choppy/jerky (on a quad core+8800GT). I’ve been constantly looking for ages for some kind of rock-solid playback solution on vvvv (as in, perfectly smooth and never dropping frames or jerking etc.) I really think I’ve tried everything by now. Video playback is always so random, sometimes smooth sometimes not, regardless of what else is running in the patches or on the computer. I also work in opera/theatre sometimes and I can’t really recommend using vvvv to people because the video playback is so dodgy. It’s a real shame because vvvv is ace in so many other ways…
hd and larger video always works like a charm untill you want to seek or switch between files often
for that purpose image sequences are the way to go up to 2048x1024 jpg-s
for videos up to 1920 x 1080 wmv is best because of gpu assisted decoding
for videos larger than hd a couple of codecs in ffdshow are a solution, last time ive tested 3840x1024 with divx,xvid and wmv vc1 (in avi container) and no problem there
make sure to use 30 fps videos because of 60 hz projectors
and set nonpow2 and wait for every 2nd frame in the videotexture
on my current machine i can play 8 layers of hd wmv
or 2 layers of 2400x600 ffdsow mjpg
or 1 layer of 3k or larger
and get 59-60 fps
and its not even a monster machine:
quad q6600 clocked to 3 ghz, ati hd 2900
and xp 32 bit because of input card drivers
and no raid either
