What do the different render settings under Magix HEVC/AAC mean?

I'm trying to set up my Vegas software to give me the best balance between rendering quality and rendering speed.

At the bottom of the Custom Settings window, under Preset, I can choose between default/high performance/high quality/low latency-default/low latency-high performance, low latency-high quality/lossless-default/lossless-high performance. What are the differences between these settings?

I've also noticed that when using the render setting with the Encode Mode set at NV Encoder, it still uses my Nvidia graphics card to render my file, even if I have GPU acceleration of video processing set to OFF in the PREFERENCES window... although it's not quite as fast as when it's set to NVIDIA mode. The only advantage to having it set to OFF is that my renders tend to be more stable (occasionally when that setting is set to NVIDIA, the render will crash before it's finished).

Thanks!

What version of Vegas are you using? Start here for user-to-user support.

Low latency is for constant size frames and no B frames for streaming- avoid those modes for general renders.

I'd just stick with default.

Of course if you use the NV Encoder it will use your GPU for rendering- that's the point of it. Your NVIDIA card has dedicated circuitry for decoding and encoding. This is independent of its general GPU calculation ability which is what setting preview to off will do. I'd leave video processing on and if you have issues change the render from NVENC to Mainconcept HEVC (CPU). You'll likely get somewhat better quality at a given bitrate than NVENC so the only tradeoff is longer render times (though depending on your project complexity potentially faster than the opposite setting of preview acceleration off and NVENC on).

Forget about rendering speed and NV encoding when you want quality. Try Voukoder

However Voukoder also has NV encoding and other encoding options too
