I pretty much have always used ..

Preset = High Quality

RC mode = vbr - high quality

Worth to mention that there is really nothing in it CPU (MC) vs Nvidia Nvenc quality render.

Perhaps the Mainconcept codec is not what it used to be.

I did a quality test and there was just under a 2% difference, in favour of Nvenc!

Also Nvenc render time was just more than twice as fast.

Used my laptop.

 

One of the AVC encoders in Vegas or Voukoder should give you files about half the size of Nvidia.

@mark-y Won't that depend on the bitrate used which is the controlling factor of file size irrespective of how the file is rendered?

I did an ffmpeg CPU encode and found that it was ~ 2% better quality than VP Nvenc, nearly 4% better than VP CPU (MC).

In all 3 cases I matched the output file sizes and data rates very closely. The VP CPU (MC) has a different GOP to the VP nvenc GOP but I don't think that matters much. I matched the ffmpeg CPU GOP to the VP Nvenc GOP.

I used the "Kimberley" 13 second FHD clip as source. Hope she's ok with that. @Kimberly-Durecki

For smaller file sizes and better quality, render with a software encoder like AVC/x264.

Hardware encoders like Nvidia are good for fast capturing, but not much else.

One of the AVC encoders in Vegas or Voukoder should give you files about half the size of Nvidia.

This is the information from one of the videos, I recorded several but they all have the same configuration and a similar size.

Worth to mention that there is really nothing in it CPU (MC) vs Nvidia Nvenc quality render.

Perhaps the Mainconcept codec is not what it used to be.

I did a quality test and there was just under a 2% difference, in favour of Nvenc!

Also Nvenc render time was just more than twice as fast.

Let's see if I understood, the AVC was slower than Nvidia? At the moment I was using the MAGIX HEVC profiles but I have noticed that when I see them on my PC they look good, but when I upload them to YouTube they look a bit bad.

For smaller file sizes and better quality, render with a software encoder like AVC/x264.

Hardware encoders like Nvidia are good for fast capturing, but not much else.

What a shame, another question.
I was testing with the Magix HEVC profiles but would AVC be more stable? And if, for example, in AVC I take a profile that says NVENC, would it be a bad idea?

I was looking for the difference between the two profiles but the truth is that it ended up confusing me more.

@mark-y Won't that depend on the bitrate used which is the controlling factor of file size irrespective of how the file is rendered?

Yes, you are correct. I should have included the words "... at about the same relative quality" in my answer.

@JUAN-PUENTES

"And if, for example, in AVC I take a profile that says NVENC, would it be a bad idea?"

I don't think so. See my previous post.

Give it as high a data rate as u think will produce good results.

Yes, the higher the value, the better the result, but I wanted to validate if there was a way for the weight to be a little less hahaha

And I did read what you published but I didn't understand well when you explained the example you did with the Nvidia Codec.
In conclusion, the normal template vs the NVENC is better by very little since the quality does not vary as much and the former tends to be faster?

And sorry if I'm a little slow, but I'm just learning about these topics with Vegas Pro.

Correct. So render out several short samples with different data rates from low to high from the same video clip.

Then play them and view them to see which is visually acceptable.

That way you can validate which ones weight is less hahaha.
