user29917: I’m working on an amateur project, and for part of my project I’ll be using some old, really, really low-res film. I’ve used some free online tools (like deep-image.ai) to upscale low-res photos before, to great success. 
I’m trying to find a similar tool for video, but all the tools I’ve come across are for enterprise or cost caboodle. 
Is there any free tool out there for AI image upscaling?

user34170: When I browse the video upscaler from the Internet, I found two kinds of video upscaling tools.

One is the video upscaling software, such as AVCLabs, Topaz, DVDFab.
Another one is an online video upscaler.

Both of them are able to upscale video in 1080p to 4K.
If you have more patience and time to observe the video upscaler, you can try AVCLabs Video Enhancer AI, because I found that it is free currently.

user6009: There's a few options I've seen listed at
https://sites.google.com/view/aiupscalingtutorials/ai-upscaling:
(in no particular order)

1. ESRGAN

An open source AI upscaler (super sampler) based on a generative adversarial network architecture.
Can be run in CPU mode, but requires a CUDA enabled Nvidia graphics card to get the most out of it.
Be sure to check out the Upscale Wiki

2. SFTGAN

An open source image enhancer that seeks to restore lost texture details from known types, made by the same team who developed ESRGAN.
Can be run in CPU mode, but requires a CUDA enabled Nvidia graphics card to get the most out of it.

3. Topaz Gigapixel AI / Video Enhance AI

Commercial super sampler that uses artificial intelligence and is made by Topaz Labs.  It costs $100, but comes with a 30 day free trial.
Produces good results with little fuss.  Easy to install, but also requires a CUDA enabled Nvidia graphics card.

4. Nvidia Gameworks

Apparently, it works quite well, but it requires a beta access pass which very few people were awarded.


Then I've also come across:
5. AVC Labs Video Enhancer AI

Commercial product, similar to Topaz Video Enhancer AI
US$40/month or $200/year
Free trial version

6. DVDFab Video Enhancer AI

Another commercial product, again similar to Topaz Video Enhancer AI
US$79.95

7. Dandere2x

Open source
I've read some good reports about this, and it may be worth checking out

8. Video2x and Waifu2x-Extension-GUI

These two frontends assist with processing video using the open source waifu2x engine
