I know this is a little outside the realm of what OBS was designed to do, but I'm trying to record 4 separate 720p cameras to 4 different files for a research project and I'm trying to figure out what system specs I would need to pull this off (if it is possible at all). My plan is to run 4 instances of OBS using the -multi switch and record a single 720p camera in each instance. I need all of the cameras captured at their original resolution.
I think I've resolved the USB and HDD constraints by getting a PCI-E USB card and an SSD RAID setup. This leaves the question of processing power. I'm under the impression that OBS will allow me to offload encoding computation to an nVidia GPU (and only nVidia). If I were to purchase 2 GPUs, I could ask two of the instances of OBS, each handling one camera, to encode using a GPU. The remaining two instances would have to encode using the CPU.
My best guess at the moment is that I should be getting a dual nVidia GPUs (GTX 780 Ti?) along with the fastest processor I can find (Intel i7 Sandy Bridge hexa-core?) and as much RAM as I can cram into the system. I am wondering if anybody has attempted anything like this or whether anyone has some idea of what system specs are required. Would I be better off using two machines? Is there some other program that might be designed specifically for my needs that I should be using instead of OBS?
Any and all help would be greatly appreciated. Thanks in advance for your responses!
