Topaz Video AI 6.1

Today’s release is a very important moment in the history of Topaz Video AI. We are releasing Project Starlight 41, the first-ever diffusion model for video enhancement.

This is a significant evolution over our existing models, and it’s the single largest increase in model capability since Video AI launched.

Even the most challenging footage can be enhanced with Project Starlight. So please, try out the “bad” footage—footage that may have previously produced artifacts with other models.

Because of its size, this model is significantly slower and more expensive to run than previous models, and requires cloud processing on server-grade graphics hardware. But this is just the beginning. Our mission as a product and research organization is to advance visual quality to the furthest extent possible—it just takes a little more processing power to get there right now.

We see a clear path towards expanding access to Starlight and other models of this generation to very high end desktop GPUs, and Project Starlight is just the start of a new series of models.

Project Starlight Research Preview

Active Video AI users can currently process three 10-second weekly previews of Starlight for free. Results will be viewable through unlisted, shareable links with the new “Compare” button in Video AI.

These previews take about 20 minutes to render if servers are available immediately, and all exports are delivered at 1080p.

Starlight Early Access

Video AI users can also render up to 9000 frames of video using Starlight (5 minutes at 30 fps).

The current introductory under-cost pricing of 90 credits/minute will change over time as our team expands access and server capacity.

Our research team is eager to receive feedback and discuss this step-change in AI video upscaling. We appreciate your involvement on this journey to Video AI’s next frontier.

Project Starlight announcement on X 8

Topaz Labs CEO Eric Yang has also written a new blog post in our Roadmap section to talk more about Project Starlight. 18

6.0

This release represents a major revamp of preview comparisons, with a tab-based interface that allows for workspace customization. Using tabs makes comparing different model settings much simpler, and brings more screen real estate back to the playback windows.

Here’s a video overview of what’s new in v6!

Introducing Topaz Video AI 6: Smarter, Smoother, Stronger!
Introducing Topaz Video AI 6: Smarter, Smoother, Stronger!

Highlights
Tabs
We’ve heard your feedback and we want to make comparison, easier, better, and more intuitive. Tabs are self contained groups of settings. You can create them from scratch or use presets. They replace for our previous preview queue and A/B comparison mode. Now rendered previews are contained in each tab, and it’s easy to compare two sets of previews, or the original. Just drag the tabs to create the view you want.

Video player
Our upgraded video player has been available in Windows and is now coming to Mac. The video player supports HDR, audio, and smooth 8K playback. Getting high quality previews in app, has never been better.
Note: HDR support on Mac is still in progress

Exports
We’ve revised the export queue to take up less space, offer more information about your exports, and make it easier to track exactly what you’re rendering.

Sources
We’ve moved the sources panel to create more work area. You’ll find it right below the timeline on the right.

Presets
The preset system has been refreshed to make it easier to find your favorite settings and quickly apply them across projects. You can select a preset directly when starting a new project. Presets are tightly integrated with tabs, you can create a tab from a preset, or save a tab to a preset.

Timeline
We gave the timeline a lot of love in this update. The upgraded timeline is faster, more responsive and has thumbnails to help you find what you’re looking for.

Live render
We’re making huge improvements to the live render system. You can render specific length chunks using the render button, and now it’s easier than ever to compare two sets of settings. Just switch into Side by Side or Split View, and press the play button to start rendering.

Other updates:

A new Preferences toggle is now available to enable/disable Cloud processing in Video AI:

Notes:

Stabilization is currently not supported as a Live Render filter in previews. Stabilization previews can be rendered using the Render button.


5.5.1

Using Topaz Cloud Credits 277, Video AI users can now offload heavy processing tasks to our servers for faster processing.

Use cases:

Processing large batches of videos in parallel: There’s no limit to how many simultaneous jobs you can queue on the Cloud Rendering service, which can greatly improve your overall output of clips.

Processing long videos on low-power machines: Cloud Rendering excels when working with videos that are 30 minutes or longer, which allows us to parallelize across more GPU instances. For users on laptops with less-capable GPUs, you can sleep your machine without worrying about renders being paused or cancelled.

Known issues:

H.265 and AV1 are the only enabled codecs for now. We plan to expand the list of supported codecs as we determine system stability. Cloud renders larger than 8K are also disabled for this release.
Video inputs under 10MB are not currently supported for Cloud Rendering.
Hyperion is not currently enabled for Cloud Rendering.
We’re excited to work together on furthering the efficiency of Cloud Rendering, and as always we appreciate your involvement and feedback!

New in 5.5.1:

Adds support for Intel ARC ‘Battlemage’ B580 and B570 GPUs

5.4

1. All-new, GPU-accelerated video player

Video AI 5.4 uses an mpv 10-based video player that unlocks incredible improvements to playback performance. Scrub through highly-compressed input videos, or massive uncompressed media with near-instant responsiveness. This new player also supports HDR displays and audio playback! The old live preview behavior with the “Render” button is also restored. Right now, the new player is available on Windows only. We are working on bringing this player to macOS very soon.

Playback of 8K video with old player:

2. Hyperion SDR-to-HDR model
This model is designed to perform inverse tonemapping by increasing the bit depth, expanding the color gamut, and brightening the highlights of input videos. It improves contrast and recovers detail in highlight and shadow areas of standard dynamic range inputs, and produces HDR10 (BT.2020/PQ) output.

Controls:

Exposure adjustment slider: This slider allows the user to increase the exposure of the scene by up to 1 stop. This adjustment primarily affects the brightness of the shadows and midtones.

Highlight threshold slider: This slider explicitly tells the model the lowest intensity level to be considered a highlight. This slider should be set to a value higher than the brightest skin-tone (or any other color where accuracy is vital) present in the video. In practical terms, we recommend starting with the default setting and raising the value if undesirable color shifts appear.

Saturation boost slider: The HDR color space has a larger color gamut and supports more saturated colors. Turning this slider up results in more saturated outputs in HDR without loss of detail. This slider will, however, lead to a color shift.

3. Rhea XL (RXL) Enhancement model

RXL is an even larger variant of Rhea, and is designed to handle complex textures in a more refined way.

The model requires significantly more VRAM and GPU power than previous models, so expect some longer processing times compared to Proteus or Iris.

Here’s a link to an interactive player window with a sample of Rhea and RXL’s output with the same settings applied. 51

RXL is currently listed as a “model variant” under Rhea in the Enhancement filter menu. This may change in future updates based on feedback and model fine-tuning.

Known issues:

Hyperion SDR-to-HDR does not currently support Intel-based macOS systems.

Update 07/11: Video AI 5.2.1 is now released with a fix for videos stored on network shares sometimes not importing correctly.

Today we’re excited to release Video AI 5.2!

This release includes the new Rhea Enhancement model, Pro seat management, Frame Interpolation for After Effects, Alpha layer support, and many UI and backend fixes.

Rhea Enhancement Model
Rhea represents a combination of Proteus and Iris. The model is intended to be more accurate in preserving fine details across a wider range of subjects, while also handling text in a less destructive way.

This model and Rhea internally processes inputs at 4x scale and then downscales to your selected output resolution.

We’re very excited to see your results with Rhea, here are some example frames from this model:

Frame Interpolation for After Effects
Today we are also launching Frame Interpolation in Adobe After Effects. This plugin addition includes access to all Frame Interpolation models for up to 16x slow motion conversion.

For more information on using the After Effects Frame Interpolation plugin, see this post in the Video AI Plug-ins forum section. 2

Alpha (transparency) layer support
Video AI can now copy alpha layers from inputs and merge them back with AI model output videos. Alpha layer copying is supported in the following codecs:

QuickTime Animation
TIFF
PNG
image

Pro seat management

After a pre-launch period with several Pro teams around the world, Video AI Pro will be officially launching later this week. This new license tier offers seat management, commercial usage rights, and multi-GPU support for teams working with Video AI.

As part of this transition in licensing, we will be discontinuing the previous implementation of multi-GPU rendering for the standard license. Our team found that less than 2% of users made use of the multi-GPU setting, and further development will be focused on multi-GPU optimization for Pro teams.

If you are affected by this change and would like to discuss further options, please contact enterprise@topazlabs.com

Bug fixes & other improvements:

Preview set saving functionality restored.
UI lag greatly reduced, specifically for long operations.

Rebuilt EXR + DPX support in-app
EXR and DPX inputs will now be correctly downsampled to 16-bit TIFF for processing, and exported at 32-bit linear color.
This function requires a large amount of available disk space on the drive selected for exports.
Support for ACES and other color formats is still underway, and our team is actively seeking different use cases for EXR and DPX to further improve compatibility.
Added focus fix feature to enhancement.
image

Improve missed focus in videos with the new "focus fix" mode for the Enhancement filter.
This feature changes the way models affect input videos by downscaling inputs before upscaling.
Two different modes can be used to control the strength of this effect:
Standard mode first downscales input media to 50% and then upscales to 2x.
Strong mode first downscales input media to 25% and then upscales to 4x.

Image Sequence options are given through a tab option now to separate UX flows for Video and Image Sequence exports. Similar to video encoders, we have added Bit Depth options for Image Sequence exports.
Removed “Auto” option for Audio Mode, default behavior is “Copy”. The UI should show an error if this is not possible for your video for compatibility reasons. (ex. PCM audio cannot fit in MP4).
Changed “Transcode” audio mode name to “Convert”.
When Converting audio, you have the option between AAC, AC3, PCM codecs. For MP4 container, you will only be presented with AAC & AC3. When exporting with VP9 + WebM container, the only codec option is Vorbis.
For AAC & AC3 you have the option to set a bitrate for the audio. AAC default is 320k, AC3 is 448k
Saved preferences from previous versions should be migrated to new preferences. ex. if you have a preference set to export as “TIFF lossless 8-bit”, your preferences in the new version should show “TIFF” for encoder and “8-bit” for Bit Depth and this should still be applied when opening a new video.
Added MKV container to extension options for VP9 exports.

Please take a look at the Video Roadmap Update 734 for more context on what we’re focusing on right now. Thanks in advance for your feedback!

Enhancement model - Iris

Primary aim of the model is to improve human faces
This model is also designed to enhance low- to medium-quality video, particularly, with noise and compression artifacts. Note, the model tends to lose details on high-quality videos
This model is trained to work on all three categories - progressive, interlaced, interlaced progressive
Please look at some examples in the roadmap post 734
Recover Original Detail

Purpose of this slider is to retain details from original source if the model’s output is overly smoothed
It adds the source texture details to the model’s output to bring back the original details
