Resolume Forum

Hey,
I'm using Avenue for a project at university. I want to show 10 transparent videos above one another, then switch to showing only one. The whole thing is controlled by Processing via OSC, which in turn gets values from an Arduino. The videos need to be in 720p resolution, so it should be a lot of work for my computer.
I've tried three different computers up until now. The first was an iMac, I don't remember the configuration, but it worked for some time and then suddenly started to stutter all the time. So I tried a newer iMac (2.4ghz, graphics card with 256ram, 6gig ram), and it stuttered from the beginning. I then tried a PC (Core2Duo 2Ghz, 3GB Ram, 256ram nVidia graphics) and it worked for some time, too (I had it running for two hours straight for testing yesterday). Today suddenly the sound became asynchronous. Rebooting didn't help.
Some information about the video files:
DXV Codec, 720p
Audio Format: Integer (Little Endian), 48000kHz, 32bit
Any suggestions? Need help fast!
Thanks!

i had problems that my beat counter stopped working.... deleting the preferences.xml in your resolume folder (in the my documents folder) solved my problem, maybe the same with your audio issue
and... the audio files should be in .wav format, and normally u use 44khz instead of 48khz (depends on the soundsystem and it's converters).

the graphic card should have enough performance for 10 layers
the new imacs have a ati 4670 or so.... i would suggest that 10 layers in 720p are maybe a bit too much for this graphic-card...

a ati 4870/5770 or nvidia gtx280/gtx460 or above should do the job on a pc/mac pro.

also the harddrive should be fast enough to play 10 720p clips simultaniously.... especially at bigger file sizes a normal hdd will have problems i think.... maybe use a little raid system or an ssd drive.... or maybe it's also fast enough to copy the half of your clips to another harddrive....

what you can try before an other hardware configuration is:
deactivating the blend modes and composition effects in the video preferences (then you only have the alpha blend for the layers)...
and if the audio is just a little asynchron (video takes longer to transmit especially if it connected through more devices) you can set a delay in the audio preferences

another suggestion - i have all my clips in dxv and my cpu is quiet bored, also in higher resolutions... so maybe it helps if you try:
to recode some of the clips to quicktime fotojpeg (at 80% quality or so) or mjpeg codecs (maybe the bigger ones). so the file should get smaller which unloads the hdd. also the graphiccard has fewer things to do and insteat of her the cpu is working on this clips.

hope this helps you!

thank u,
i'll check it out!
