The new Direct Comparison UI and Nyx v2 (October 2023)

Direct Comparison UI

Video AI v4 is here with an entirely new system for generating previews. This has been a highly-requested change and we’re very excited for our users to work with the new interface.

As our team adds more models and controls to Video AI, we found that users were looking for new ways to construct different filter combinations and view the results from within the app’s interface. This update is meant to provide power-user flexibility while retaining the core functions of the app.

Compare multiple models with ease: This new interface expands users’ toolset for finding the perfect AI output.

View 1 and View 2: Video AI now allows editors to freely switch between reviewing input clips and previews. Keep the original input visible, or A-B compare between two different previews to see the exact differences between versions.



Comparison view in action:

Comparison view allows users to generate previews on either side of the player view. This is useful for comparing two different models, but can also be used to compare Auto and Manual parameters of the same model:

Customizable player windows:

Views 1 and 2 can be assigned to any preview generated in Video AI. Using the Previews panel, users can select which settings to display on the left and right sides of the video player.

Multi-area previews

Another major change involves the organization of Previews. We’ve found that users are interested in previewing different areas of the same input video, and this change makes it simpler to see which regions of the timeline have been rendered as Previews.


Refreshed UI and filter icons:

Along with these changes to the preview system, Video AI v4 is sporting a new look with even more space on-screen for your content. The right-side panel has been reworked to avoid scrolling on smaller displays and make better use of monitor height:

Nyx v2: Improved accuracy and a new 2x scale mode

  • The Nyx model, originally launched in version 3.5.0, is now updated to v2 and includes a 2x Upscale mode.

  • Nyx v2 is even more accurate when working with high-resolution inputs and is able to precisely separate noise and detail. Cinematographers can now confidently shoot at high ISOs and generate production-grade night shots with ease.

Other improvements

Changelog from September roadmap:

  • Add “Black and White” toggle to video input options.

    • This option will desaturate output to prevent models from adding color to Black & White videos.
  • Add “Telecined” toggle to video input options.

    • This option will reverse the telecine process and deinterlace your video to 23.976 fps before applying AI models.
  • Adds detailed tooltips to Output Settings.

  • Enables ProRes, H264/5 and AV1 encoders for Linux.

  • Fixes many color-banding issues seen in the in-app player.

  • Changes filter tooltips so they are now also seen when you hover on the filter name and not just the icon.

  • Adds Iris options to select between Medium/Low Quality. Medium will use Iris-v2, Low will use Iris-v1.

  • Adds 1x & 2x deinterlace options for Interlaced videos when keeping original fps.

  • Adds detailed tooltips for all preferences.

  • Adds detailed metadata for Iris & Nyx enhance models to exported video file.

  • Adds “Noise” value for enhancement models to video metadata when not zero.

  • Fixes issues selecting “original” fps option in fps selector.

  • Reduced model loading time for Nyx, Proteus, Iris Auto and Relative to Auto.

  • Adds 10-bit for NVENC AV1.

  • Automatic parameter estimation now runs on 8 frames instead of 20.

  • Fixes for Nyx as second enhancement: will now automatically make the first enhancement perform upscaling.

  • Iris-v2 is supported on Intel ARC.

Please read the release threads for 3.5.4, 3.5.3, 3.5.2, and 3.5.1 for the full list of changes in each release.

What’s Next?

We have several foundational improvements in the pipeline that should significantly improve how useful Topaz Video AI is to you.

Workflow improvements

  • Direct integration with popular NLEs
  • Allow offloading processing to a cloud backend
  • Allow pausing and resuming processing

We plan on shipping most of these improvements before the end of 2023. Please apply for the video beta program if you’d like to shape the development of these features. Thanks, and we look forward to hearing what you think!

One fast question:
Does TVAI 4 properly exploit the technology of the new AMD Ryzen 7000 “X3D” Desktop version, such as 3D V-Cache and the new AVX-512 instructions to speed up conversion, improving performance for the CPU-processed part? Can you officially confirm this for us?

Thanks!

I knew It I should have bought AMD

Just because there is a partnership between two companies doesn’t mean that the two products will work the best together.

For example, apparently Topaz Labs and Intel work closely together to try and improve performance on Intel GPUs. In the beginning it resulting in an improvement for Intel GPUs. But then things broke and for the last 6ish months, Intel Arc GPUs haven’t worked properly on most AI models. And Topaz Labs are frequently told the community that they are still working with Intel on improving things.

Apparently Topaz Labs and Apple work together in some situations. Some AI models are broken on Apple Macs when using CoreML or something like that, and so they’ve had to be replaced with slower versions (and they’re still like that in the most recent version, although the issue was only introduced recently, so it could be argued not enough time has passed for Topaz Labs and Apple to properly investigate and fix the issue).


There’s also the other factor. This video seems to suggest/claim that Topaz Labs is optimising for Ryzen AI. A AI engine in select Ryzen laptop CPUs (at the moment). In the case of laptops with a Ryzen AI compatible CPU and a weak GPU, then using Ryzen AI will likely be faster and/or more power efficient than not using Ryzen AI. But it may not be as fast as if you’d brought a laptop with a mid to high end AMD or Nvidia GPU

I know that Topaz optimizes for Nvidia tensor cores. I wish they would move toward a more universal GPU accelerated AI platform like DirectML that could better leverage the performance of different GPUs aside from just Nvidia ones.

TVAI appears to already use DirectML. I believe AMD GPUs are the only devices that use them at the moment.

There’s quite a difference between „uses“ and „is optimised for“…

No “November” Updates for TVAI Roadmap?? :roll_eyes:

November roadmap updates are just a few days away, but we do have an exciting TVAI feature release planned for later today!

Will there be a roadmap for December? I noticed there wasn’t one in November. Would love to see what new and exciting features are coming next!

Or, at this point in time more January roadmap.
