Nvidia NVENC on Quadro1100M

snacky wrote on 11/10/2017, 4:44 AM

hi,

I was testing nvidia encoder implemented in V15 and have serious issues with encoding 4k using this codec

The only template that works normally is default one, but it's limited to 24MBit in average

Even if I set 135Mbit, it's limited to around 50Mbit in result file.

When I'm trying to use other nvenc preset and rc mode, I'm getting black screen or artifacts.

Any advice how to get higher bitrates and not loose quality in final file?

Using Nvidia latest drivers for GPU

Just wanted to ask: Have you reverted to an older driver? New drivers tend to have issues such as what you're having crop up.

And honestly, 1GB for 4K might sound almost nothing but my old laptop could still render 4K video on Vegas Pro 10 (before Magix took over) with a 1GB GTS 250M. Didn't take long but the laptop became a space heater.

Download software like GPUShark and check how much GPU ram is used while rendering.

will check in a minute with GPU-z

yeah, older driver might be better - the main question is which one

Only one way to find out of course! Might be a pain though.

RAM usage not so very high when rendering, so don't think it has something to do with the problem

was trying with 2 older drivers for quadro:

376.62

362.77

issues are still the same
