VEAI only output a low AAC stereo downmix of the audio source of the video.
If it’s a video upscaler and audio has to be re-muxed then why do they have a poor quality ‘keep audio’ function?

Is there a noticable difference between hardware/software H265 encoding?
Certainly for helping doing sync or providing a basic audio track for checking the final video.

As in quality!
While I have seen quality improvements in Nvidia between pascal to turing to now ampere I find software encoding H265 still gives a better result at a same bitrate or output file size. It is the reason I choose to have a Ryzen 9 3900x processor for software encoding at the time. There is no comparison for speed. hardware encoding can be blazing fast but 24 threads of CPU all encoding at once using FFMpeg is not that slow. Now ad extra Avisyth+ processes and even hard encoding can slow down.

Typically yes but what I’m comparing is CPU-software H265 encoding to NVenc hardware encoding.
The creators of h.265 want you to think that. In reality, you need about 3/4th the bitrate for quality equivalent to h.264. Not worth the increase in CPU to encode and decode IMO.
I downloaded and installed v2.4.0. However, after installation it refused to download models for preview. Even waiting an hour, the message just stayed on the screen about taking a minute or two. A check of network traffic showed no download in progress at all. Even downloading all the models (about 35 GB) I wanted didn’t get rid of the message. Re-installation did not work and resulted in the same message. I finally downgraded back to v2.3.0 and that works without any issues. I am running the latest studio drivers on an Nvidia GeForce GTX 1660 Super, Intel i5-10400F 2.90 GHz CPU.

I should add that v2.4.0 installed and ran just fine on my notebook computer with an Intel i7 8th generation CPU and a GeForce GTX 1050Ti. So, it’s quite a puzzle to me why it won’t run properly on my desktop.
Maybe anti-virus or firewall is blocking the download?? Did you install as Administrator?
Here is the test result conducted by MSU.

Significantly, both in resulting video quality and file size.
Nvenc will give you the quality, but at a much larger file size. It should only be used for livestreaming. Use software to get good quality and better compression.
Hi - what is the best setup when using an Apple system? Does the M1 chip enhance performance or is it even compatible? Would adding an external GPU to an iMac help? If so, what does anyone recommend?
I have a 2019 iMac running Big Sur 11.6 – with 40GB of RAM, 3.7 GHz 6-Core Intel i5, Radeon Pro 580X 8GB internal GPU.
Just looking for any way possible to speed up the rendering.
I’m currently getting 1.6 sec / frame for Chronos HD doubling the frame rate with 1280x720 video.
With other options, I get .2 sec / frame when working with 720p video.
Hoping to find a way to cut this time in half with any type of Mac machine or add-on.
Thanks!

Thought I’d share a Computer/GPU direct comparison. I just received an EVGA RTX 3060 Ti from the queue. A couple of months ago I purchased a RTX 3060 through the EVGA queue so this might be of interest. Both computers have very similar components with the slight exception of the CPU’s. Anyway the listing is in the image.
The image is a spreadsheet I made to do a quick check on time versus total frames. The test video is 1280x720 scaling to 1920x1080.
Just to be clear also the GPU’s were $400 and $470 plus tax and shipping.

That doesn’t seem to be the issue, especially since I could easily install and run v2.3.0 without any problems. There are also reports (above in the thread) of other people having problems with the program just sitting there at the downloading model stage when previewing, so it’s probably a program bug that only appears in a specific set of circumstances.
