recently got a 4070 and testing out some NVENC AV1 rendering. I noticed that with the SVT there is a CFR rating that can be set., which i believe auto adjusts bitrate to keep the quality consistent while saving space? I have mine set for 40 for my needs

On the nvenc av1 encoder, i do not see the CRF, but i see the constant quantizer, so i set it to 40 as they show up as qp=40 in both of the encoders.

However, after rendering with the 2 different encoders, the SVT file size is 373MB, while the nvence is 1,64 GB in file size. Can someone explain the difference in the 2 encoders as both show the settings as qp for the settings.

Ive done some testing and for me setting it on constant quantizer, quantizer level 40, preset ultra fast

seems to be pretty good looking for myself

You need to use davinci resolve studio in order to use the plugin.

the non studio does not support plugins.

The next version will be based on FFmpeg 5.1. I don't have any release date yet.

Great news! Just joined your patreon.

While researching more on AV1 encoding. I came across this on reddit to encode a video base off the VMAF score called ab-av1

it Uses ffmpeg, svt-av1 & vmaf together to encode the video.

This could be interesting as it can help people with not as much knowledge like me encode videos in good quality without tinkiering through a lot of settings.

It can be found here. https://github.com/alexheretic/ab-av1

Didn't know CRF is available for svt-av1. Adding it now ...

Edit: Need to migrate to FFmpeg 5.1 first.

When can we expect a version with FFmpeg 5.1?

In vegas pro, you can go into tools, scripting, batch render and you may be able to select multiple templates you created to have multiple files created

ok, i thought they were the same because i did not see the option for CRF in the options. I also do not see the option for the preset number.

I guess my email notifications are not working, I just decided to check out my post here.

Would the constant quantizer be the same as the CRF?

I've been using HEVC with Voukoder for a while now, but After the updates to the AV1 after finally updating, rendering does not take a long as it used to with the SVT support. For 1440p game recordings i have it set for 2,000 kbit with a max bitrate of 10,000 kbit, ultra fast preset, and main tier. The quality of the videos look really good in my opinion. a 20 minute 1440P video ended up being 340 MB in size. Very good file size to quality compared to h.264 and h.265(HEVC)

I dont see too much information for AV1 out in the wild. I am wondering who else is using the AV1 codec and what settings they are using. I haven't played mych with the constrained variable bitrate, or the constant quantizer yet.
