I would dedicate at least one PC for work and an other for gaming etc. at home.

For example, you can connect up to 6 PCs to a single LG43UD79 monitor and display 4 of them at the same time.

I would dedicate at least one car to driving to work, one for grocery shopping, one for trips, etc…

But seriously for many this solution may not be affordable or practical.

Any ideas (to the devs), when a build with this will be available?. I’m holding out for this feature to be implemented.

Just started using this app today and this feature would be fantastic.

Any idea if/when the devs plan on implementing this?


Oh yeah, that would be a really cool addition. We export for now in ProRes422HQ and can’t wait to export to prores4444. Play/pause button is a much, much needed feature…

I was thinking the same thing. I can’t leave my computer running overnight as it is wicked loud when doing so, and my sister hates the noise which is why I usually have to cancel the process, usually after nearly 3 hours of rendering and then start over.

I’m 17 and we live in a tiny cabin and we share a bunk room, she gets the top bunk. The room is only about 8 feet wide and 15 feet long so the computer HOWLING at night bothers her like crazy.

If you render to frame you can start & stop whenever you want. It takes up a ton of space plus you’ll have to stitch it together and nix the audio back in after but it’s an option.

This. I am waiting patiently, but it has been a long time. Any news from the devs?


Being worked on as we speak…

Sounds promising! Thanks :+1::sunglasses:

I would like to see some example commands, I’m trying to use ffmpeg via cygwin terminal on windows.
For example when frames are named 000000.png, 000001.png 000002.png etc…

Btw does it need to be 30 or 60 fps, or can I use 120fps?


ffmpeg.exe -framerate 23.976 -i “image folder path%6d.jpg” -map 0:v -r 23.976 -c:v libx265 -crf 24 -preset slow “out path.file-extension”
Something like this. You can do bat files too. Just add another % to the input path.

it’s not working. could find no file with path etc
I have a folder named Input with image frames under D drive so I typed

ffmpeg.exe -framerate 59.920 -f image2 -start_number 0 -i “D:\Input%%6d.png” -map 0:v -c:v libx264 -crf 16 -preset slow - r 59.920 vf format=yuv420p “D:\Output\Output.mp4”

I can’t see why it doesn’t work

That’s the bat file format. You have to give the full path to ffmpeg.

In that case, the solution seems to be;

cd D:
ffmpeg.exe -framerate 59.920 -f image2 -start_number 0 -i “D:\Input%6d.png” -map 0:v -c:v libx265 -crf 18 -preset slow - r 59.920 vf format=yuv420p “D:\Output\Output.mp4”
And I had to manually create a folder called Output, otherwise it says “no such file/folder”

Well, thanks

Had the same issue, converting Hi8 to 4K and process takes 4 days. It puts a lot of load on the system that’s its unbearable to do any work.

What worked for me in Win 10 - Run Task manager / resource monitor / CPU and suspend Topaz Video Enhance AI Process. It will give you warning that the progress might be lost but works fine. Was able to suspend and resume the process several times during the week of generating the video

Yes Please!!!

My use case is simple, I have dozens of old videos I took in the 80’s, 90’s, and early 00’s. These are variously analog video which I have digitized or DV which I’ve moved from tape to disk. As the quality of these is limited, I want to run them through Topaz to bring them a little closer to modern visual standards. My processing chain looks something like: Upscale 2x > Deinterlace > Enhance.

I am running this on a powerful desktop. 20 Core Xeon with a base speed of 3.7 GHz, NVIDIA Quatro M6000 Graphics Card, 64GB of RAM, high performance SSD.

The videos I am processing are from 17 min. to 2 hours in length. Regardless of whether I am using CPU or GPU processing, the time to process a single video through the above chain can easily hit 10+ days. As this is my primary workstation I am unable to dedicate such a large block of uninterrupted time to Topaz processing. I believe Topaz should support the ability to stop processing and re-start it from where the process left off at a later time – this would of course likely involve some kind of checkpoint file. Without this ability, the usefulness of Topaz for video longer than a couple of minutes is, practically speaking, quite limited.

(Not to mention for those of us that live in areas where there are requests to temporarily cut back on power usage - think CA in the heat / wildfires and/or rolling black outs - this feature is REALLY needed.)
