I'm working on building up a computer that will be for recording only, primarily one camera for now. I'm creating training videos. My business is IT, so I had this old retired server laying around:
Motherboard: SuperMicro X8DTH-6
Two Xeon E5504 2GHz CPU's
12 GB RAM
It has lots of PCIe 2.0 full-height slots which I thought would be good so I could add multiple capture boards
I have one hard drive connected directly to the MB for the OS to boot/run from. 7200RPM
It has a 3-Ware 9650SE-4LPML RAID controller and I have 4 2TB 7200 RPM drives on that in RAID 5.
Running Ubuntu 20.04
I put in a BlackMagic DeckLink Mini Recorder 4K into which I have my Canon HF-G30 connected.
For video I went with the ASUS Nvidia GeForce GT 710 for two reasons: I wanted the 4 HDMI outputs and it supports PCIe 2.0, which is all this old motherboard supports.
I installed the latest nvidia drivers from the Ubuntu software repository
Inside of OBS, the preview video is perfectly smooth.
But, when I hit record, things fall apart. Video preview is slow and jumpy. On the OBS Stats screen, the Frames missed due to rendering lag starts going up quickly. The recordings reflect that: jumpy, audio out of sync, etc.
I've tried every recording setting combination I can find. I've combed these forums for GT710 info and found conflicting info on if it supports NVENC or not, but I've tried it with that and with just x264. I've tried saving to both the OS drive and the RAID drive. Nothing has worked so far.
There are so many places that could be the bottleneck -- this old motherboard, old Xeon CPU's, low-end video card, etc. Looking for seasoned/experienced input on where I should start.
If a better video card is the answer, what's something that will work with my limit of PCIe 2.0? I'd like to have support for at least 3 monitors if not 4.
Thanks!!
