Hello,
I use Modul8 since 4 years now and I still find it a wonderful piece of software but I have some questions about performance and video processing. I have worked with Conduit Live, it is a complete different approach (you have to built yourself everything from scratch with nodes) but performance in LIVE video processing are way beyond what you can expect from Modul8. As I say, I will continue to use Modul8 because it is generally a lot more adapted to my project (complex dance and theatre show), but I dream of better performance.
So let's go !
A- In a config with 4 video cards, which one will be used to do the opengl processing ? The one used for the software interface (and so, the system menu bar) ? Or every card used to output videos ?
My config :
MacPro 3,33 Ghz x6 / 24 Go RAM / SSD system 256 Go / 3 * 2 To 7200 RPM RAID 0 (Stock) / SSD Video Live Project 256 Go
Slot 0 : Nvidia GTX 580 3GB (thanks NVidia and Netkas)
Slot 1 : NVidia GT 120 512 MB
Slot 2 : Nvidia GT 120 512 MB
Slot 2 : Nvidia GT 120 512 MB
B - Could you give more detail of your video engine to better tune my system (I guess it is based on OpenGL) as I haven't found much details on the forum ( except JPEG 75%...).
C - Do you plan to make a 64 bit version of the software / Will it change anything about memory management and limit ?
E - Do you plan to use tech like OpenCL or CUDA to accelerate video treatment ? Is it interesting ?
F - a real life example : in a complex project with all 8 sets used for different compositions (5 to 10 layers each), when I play set 1, then 2.... arriving to set 8, videos are sluggish. If I play directly set 8 (only after a fresh restart, restarting only Modul8 doesn't change anything), videos play perfectly smoothly. I don't think it is a RAM problem as I have tried with and without video RAM catching. It seems to be related to RAM or whatever on the video card. It is very annoying. Any idea of what it could be ?
Thank a lot,
Philippe.
