NVENC hardware encoding

[mxk]

Heyo,

 

I've been editing together some videos with my current PC (specs in the my signature) on a program called Shotcut. My CPU is somewhat old and very under powered, but my 1070Ti has NVENC hardware encoding and I think I'm able to use that when I render my videos (1080p60 CSGO clips). Is there any real advantage for me to use the hardware encoder?

 

Thanks!

nvenc looks much worse, so id just take the time and let x264 do the work. Otherwise custom ffmpeg setting is the way to go.

advantage is obvious, it allows systems with crap CPUs to record properly. Drawback will be relatively poor quality or compression.

In games that's super helpful, but just a render being the only task (so no game) it should be fairly easy to compare side by side for gauging which is better for the task.

I honestly have no idea what settings I can use in my render to get my video looking somewhat close to my shadowplay clips. I have the option to use libx264, and my clips are 1080p60 50mps. What would be the bitrate when I reach diminishing return in terms of how close it looks to the raw clip?

at that bitrate you probably won't notice.

 

I forget shotcut options, but basically you tell ffmpeg to use nvenc_h264 as the export option. Its probably under nvenc advance options.

Okie dokie, I'll take a look. Thank ya.

Hey mate, you can see the difference between various NVENC encoders compared to x264 here.

 

Yours is a Pascal version.

 

If you can customise the settings, you can get a low more using preset=slow and you can enable lookahead 64 and GoP as many as 480 frames. This will give you a bit of a boost. If you can't customise the settings in your software, then you might be stuck with the "hq" values in the graphs that I linked.

Thanks! Just a tiny heads up, you linking your own site is a form of advertising which I believe is against the forum's rules, but it did help a lot!
