Hi All,

New vMix user here, and I am hoping to get advice from the "brains trust" of experienced users.

We are looking at using vMix to bring in multiple (around five) TCP Pull streams from Teradek Cube/Bond units (via Teradek Core, over bonded 4G) at 1080p/30. These will then be mixed and sent back out for streaming.

Our current computer has 2x GTX 1080 cards, but we are looking at upgrading. Our budget would allow for either a RTX 2080 Ti or a Quadro P5000.

From doing some research, the Quadro P5000 seems like the logical choice since it has unlimited H264 sessions along with 2x NVENC chips.

I also found another post on the forum (https://forums.vmix.com/posts/t18487-NVIDIA-P5000-VS-RTX-2080TI) which comes to the same suggestion - but endorses the RTX5000 instead since it supports H265, but the downside is that only comes with 1x NVEC chip.

Would the P5000 allow us to comfortably stream and record the mix in H264...also also potentially record all the incoming cameras in H.264 (rather than MPEG2) which could be more conservative on space...and also easier to edit (e.g. in Final Cut Pro) than .TS files?

Alternative suggestions about other suitable cards would also be welcomed, if people have differing opinions/thoughts.

Thanks!

Thanks for your reply. We don't have an intention to run dual video cards - we are just choosing between those two options.

We reckon our budget can extend to the RTX 5000. Do you think that it's better than the P5000 - given that the RTX 5000 only has one NVENC core, whereas the P5000 has two cores? I am guessing the logic is that the RTX5000 has improved performance so it only needs a single core rather than two...but I'd be interested in whether that's actually the case in real-world usage with vMix.

The computer is a bit of a multi-purpose machine (e.g. we use it for HTC Vive VR as well). Everything we currently run works great just on a single GTX 1080, so if that's the case do you think that we'd have any performance decrease in those applications using the RTX 5000 - or if anything would it be an increase in performance?

well you can do this also. :-)

Have you tried this, and do you have any comments regarding stability?

Not sure if anyone is still watching this but I have installed the patch but I am unable to get more encodes then 2.

I have a laptop with a 1060i 6gb GPU.

I have uploaded the latest drivers and installed the relevant patch successfully but when I try to do more then 2 encodes with Hardware encoder I get dropped frames. I have run both before rebooting and after and also run the NvencSessionBump after rebooting with no success.

There was a link to how a small program that you could test how many consecutive session you could run but that link no longer works.

Can anyone offer any advice?

How many encodes are you getting simultaneously with the hack? What format are you encoding? 1080p 60/30 something else? I am VERY interested in this!! I am doing a build and if I don't have to go Quadro I would be thrilled!

Thanks in advance!
