Hey,

Yes It's legal and it is called vegas pro 21.0.

Could you do one of the benchmarks in my signature and report your time?

Builds of 21 up to 208 may have higher overall GPU usage bur 315 has higher video decoding performance with a new decoder. Depending on the project one build may be faster than the other.

Try the MagixAVC NVENC render template, not Mainconcept.

With the modern class of i7 processors, the CPU runs at less than 50%, saving a lot of energy and heat, while the GPU core is pegged above 90%.

My new 12750 i7 with Intel graphics hasn't run more than 4% CPU even on UHD ProRes rendering, and it runs like a cool rabbit. I think that is a good thing . . .

Keep in mind, that when GPU encoding, you aren't using the entire GPU no matter what app you're using. If encoding to NVENC, for instance, you're using the NVENC encoder built onto the GPU, but those shader cores aren't doing much other than assisting with the timeline processing. Your encoder might be maxed out, but you may only be using a small percentage of the rest of the GPU at the time (and this could be due to not all the effects you're using being GPU compatible, among other things). So, right off the bat, expecting 100% GPU utilization when encoding isn't a good metric to go by.

That said, as VEGAS continues work on its new engine, we'll see better and better GPU utilization.

If you're transcoding at 1440P video and encoding via NVENC encoder you shouldn't be seeing 100% CPU use unless file being decoded is heavy computationally and Vegas is using the CPU for decode.

Yeah I'm using magixAVC NVENC with the help of a ryzen 7 3700x and a 4070 rtx. Ah okay... then that answers my questions. It's natural then that my 1h 15min video takes about 1h 40min to render.

Also I do not know if you guys have the same issues but doing any type of color grading directly in vegas makes the preview laggy as hell, and on top of that the same video takes 5h to render instead of 1h & 40min just because i've done the smallest color change or something...

Make sure the GPU decoder is activated, as a test, this is a straight transcode, no scaling, no fx, just a single 1440P AVC capture encoded to 1440P NVENC . You're using 8 core, mine is the 12 core AMD, so maybe where I"m using 70% CPU you'd be using 100% I forgot to use the MagixAVC encoder , this is via Voukoder but similar result just a bit faster.

The color grading panel is very slow, it would not use all the capacity of the processing power of your 4070, it's not able to for some reason and that causes the slowness.
