‘Topaz Video AI’ Review: Video Processing Using Machine Learning

June 21, 2023

Jason Bowdach shows why you might use Topaz Video AI for difficult video manipulation tasks such as upscaling, retiming, and stabilization.

A powerful stand-alone alternative for upscaling, retiming, and sharpening video images

Unless you’ve been living under a rock, you’ve certainly heard about the recent Machine Learning revolution (marketed as Artificial Intelligence) – from ChatGPT and Google Bard for text, to Midjourney and Stable Diffusion for images. If you’re still feeling a bit hazy, Mixing Light contributor and industry rockstar Katie Hinsen created a fantastic introduction to Machine Learning when it took over NAB almost five years ago in 2018. Rereading that article in 2023, my main takeaway is that we’ve come a long way, but the general concepts have not changed much – we just have more computing power.

By the end of this Insight, you should understand:

  • What is Topaz Video AI?
  • Its main features and how it differs from the tools in Resolve (or other NLEs).
  • Whether you want to try this technology/application within your workflow or business.

I don’t think Topaz Video AI is for everyone – but it’s tech we all need to watch. It’s also a good tool to learn how different machine learning models can be used to solve a single problem – with differing results.

Introduction to Topaz Video AI

Topaz Video AI  is a 3rd party stand-alone software application for Windows and MacOS that uses machine learning (ML), or, if you believe the hype, artificial intelligence (AI). Topaz Labs also has a less expensive application for still images, Topaz Photo AI – which I won’t be covering in this Insight. At the time of publication, both applications include one year of software updates in the purchase price. Annual (optional) upgrades are currently priced at a 50% discount on the initial purchase price.

The main features of Topaz Video AI include:

  • Upscale/enhance videos to higher resolutions, making them appear sharper and more detailed (similar to Resolve’s SuperScale, which requires a Studio license, but has additional features)
  • Retiming (Optical Flow style slow motion, a paid Resolve Studio feature)
  • Deinterlacing  (also a DaVinci Resolve Studio paid feature)

Most “AI-assisted” applications like  Topaz Video AI (TVAI) employ a collection of predefined algorithms (typically called “models) which are constructed using Generative Adversarial Network algorithms (GAN) to recognize specific patterns (interlacing, video noise, human faces, skin tone, etc.) and respond. Applications using GAN tend to have several “models” you can choose from, representing various datasets (situations) used to train the model.

The software uses various machine-learning algorithms to analyze and understand the content of a video, including motion, texture, and color. Then it applies sophisticated ML models to increase the perceived resolution. Its goal is to improve the motion and detail of the video. The result should be a higher-quality video that may look better than the original source.

    How does it compare with Resolve’s SuperScale option?

    • Evan Anthony

      I feel it’s better.

      • Its certainly better than SuperScale in my opinion, but its far more resource intensive. Depends on how much time and “computer power” you have available.

  • Ed Rudolph

    Jason, have you found any automated tools for dealing with U-Matic dropouts?

  • Ed Rudolph

    Thanks, Evan. I’ll give it a try.

    I have resisted getting Topax for several years because I thought it was an overpriced piece of junk. But I just ran into a situation where a client is trying to repurpose a standard-def documentary from the early 2000s and use it for a revised HD version in 2023. Resolve could not solve the interlacing problems I was seeing with the surviving 59.94i SD version, so I did a short test with Topaz… and damned if it didn’t look totally acceptable. You can see it’s “not-quite” real HD, but it’s absolutely acceptable in terms of picture quality. Jason’s recommendation helped me wind up with a happy client and a better-looking show than had I just tried to do it myself.

    Thanks Jason!
