Hello everybody,
Unlike the x264/x265 codecs that have an Encoder Preset Slider that goes from UltraFast to Placebo, the "H264 (NVIDIA NVenc)" slider is in this order :
- High Quality
- High Performance
- Fast
- Medium
- Slow
- Default
Does "High Quality" equal "Slowest" and "High Performance" equal "Faster" ? In this case it would be useful for us NVidia users to rename these presets to make them more clear. Thanks
PS : I know that hardware encoding doesn't give great results, I just use it to quickly transcode a video to a format readable by Sony Vegas without any quality requirement.

Re: [NVEnc Encoding] Strange quality slider
HQ and HP are very likely identical to Slow and Fast. This is just how Nvidia presents the presets.
They've got a newer preset system that's more akin to x264 that we plan to implement next year sometime that's a little less confusing.
That said, the presets are not identical to x264 since the NVEnc encoder only supports a small subset of the features that x264 does for example. So don't assuming at RF20 @ Medium will be the same as x264. It'll be very different

Re: [NVEnc Encoding] Strange quality slider
Hi dr0, if I understand s55 (correct me if I'm wrong), he meant that HQ is identical to Slow and HP identical Fast, so the actual quality Slider is more or less this :
- Fast = High Performance
- Medium
- Slow = High Quality
- Fast = High Performance
- Medium
- Slow = High Quality

That's basically how it behaves on my system (older 1060)

Okay, thanks for the explanation.
