Hello,
For multimedia presentations, we use an Optiplex 7010 I3-3220.
The old method was recording on the camcorder and then transfer the video into a software video editing and then upload it to Youtube.
I was looking to optimize this and I found out we could use OBS to directly stream into Youtube.
I bought a Avermedia LGP2+ (it was around 125$ USD) to capture the HDMI camcorder output (Canon HF R800).
I read alot about this device about telling there is a delay versus Elgato, I found an video to sync audio (http://obsaudiosync.com/ )
The offset was around 450ms, but considering the I3-3220, I could only do 480p with x264 (bitrate: 2500).
Here the youtube output (x264) : https://youtu.be/5f3BHGmXoAE
Ordered an used I5-3570 and GT730. Could do 720p/30 fps (bitrate 3500) with audio 300ms offset.
I noticed NVENC was a little off on audio sync test so I opted x264, was fearing an audio drift.
But yesterday when streaming, it used NVENC (silly me) and it went really good. (NVENC: https://youtu.be/fFSxhBZL-wo)
Using HWmonitor, OBS takes 50% of the GT730 just previewing and when I record or streaming it goes up to 100%.
I had some bad bitrate (red block color) and showed the network loss some images.
Is the network the culprit or the GPU with NVENC? ( you can check at 9:53, the video lagged a bit)
Should I opt x264 with I5-3570 and 3000-3500 bitrate ?
Trying to use Quicksync but it didn't show with I3-3220 nor I5-3570, might check the Dell Bios...
Also, OBS uses up to 50% when encoding x264 with the 3570, should I try 1080p or just play with the advanced setup (veryfast -> faster/fast?)
