You can launch Astra using either method listed below:


: you can bookmark this for direct access.

Once logged in, you will be taken to the Astra Cloud interface dashboard.

Select your video file from your computer.

After the upload is complete, you will see the model selection options.

Choose the model based on your needs. Available options include: 

 (Starlight Precise 1, Starlight Precise 2, Starlight Fast 2 Beta)

Each model offers different speed, quality, and frame length capabilities.

These settings allow you to control the final video quality and smoothness.

Use the timeline controls to define the portion of the video you want to render: 

, expand the selection to cover the full timeline.

You can monitor the progress and download the final output once rendering is complete.

Starlight Precise 2 supports 450 frames at 30 FPS per video

Starlight Fast 2 is now officially released, offering fast, high-quality enhancement and supporting videos up to 5 minutes in length for quicker, efficient results

Astra currently offers limited file compatibility, with more to be added in the near future.


At this time, Astra supports only H.264 MP4 video for both input and export.

Improved unsupported file error messaging

VFR videos are not currently supported.
Recommendation: Convert VFR files to Constant Frame Rate (CFR) before uploading.
Improved VFR detection and messaging are in development.

Below, you will find information on Astra's file upload limitations. 

There is no strict upload file size limit enforced on the backend.

For best performance and reliability, we recommend keeping uploads under 

Frame limits are enforced per single video render and vary by model.

These limits apply to a single video render.

If your video exceeds the model’s frame limit:

Use Astra’s Scene Detection to automatically divide your video into renderable scenes

This allows longer videos to be processed in parts while staying within model limits.

Quick Start 

Astra is a web-based AI video enhancement platform designed for creative upscaling and stylized refinement. It operates entirely in the browser and leverages advanced AI models to enhance visual detail, clarity, and structure.


Astra is optimized for modern creative workflows, including AI-generated content and stylized video production. It is not designed as a traditional archival restoration tool.

Platform Type: Web-based (Cloud Rendering)

Rendering Infrastructure: Cloud GPU servers

Astra processes video entirely in the cloud. Rendering capacity is prioritised for active subscribers.

Getting Started With Astra

Monthly credits do not roll over. Unused credits reset at the beginning of each billing cycle.

Higher frame rates (e.g., 60 FPS or 120 FPS) consume credits proportionally based on total processed frames.

Cloud credits are generally non-refundable once used for successful renders.

Plans & Credit System

In this article, you will learn about the available modes and models in the Astra Cloud App.

Purpose: Enhancement with minimal stylistic deviation.

Preserves original structure and composition

Render Limit: 9000 frames at 24 FPS per render

Best For: Professional workflows and accurate upscaling.

Purpose: Allows artistic interpretation and generative enhancement.

Subtle: Maintains closer alignment with source footage

Bold: Introduces a more noticeable stylistic transformation

Best For: AI-driven workflows and stylized outputs.

General-purpose enhancement model suitable for mixed content types.

Highest-fidelity model for long-form video enhancement.

High-fidelity enhancement model designed for short clips.

High-efficiency enhancement model designed for faster rendering and longer video sequences.

Maximum Output Resolution: 3840 × 2160 (4K UHD)

Outputs beyond 4K are not currently supported.

Frame interpolation increases the total frame count and, proportionally, increases credit usage.

Improved file validation and error messaging

Dedicated archival restoration product (Restore)

The Original and First-Ever Diffusion Model For Video Enhancement

Project Starlight is Topaz Lab’s video enhancement model that is capable of enhancing previously impossible footage. This can be anything from tricky 8/16mm film, VHS footage or low res AI generated content. This specific AI Model has since been renamed as 

Because of the complexity and scope that this model requires to process, this model is significantly slower and more expensive than previous models. For that reason, it currently requires cloud processing on server-grade graphics hardware and this model can be accessed via our cloud app, 

We recommend testing standard definition videos that have less than ideal results with our previous models, though it’s not limited to that resolution. Project Starlight will currently output 1080p and 4K results.

Here’s a quick start guide on how to use Precise.

To begin, make sure that you are logged into Astra. 

Once logged in, drag and drop your video or use the 

This is the original AI model that’s more accurate to the source video while doing some enhancements. Precise has two settings.

: This produces a much quicker result but may have a little less details.

: This is the original iteration of the AI model that produces high quality details, but does take much longer to produce higher quality outputs.

Another variation of the model, essentially generates more embellished details and content based on what’s in the video. Creative has two settings.

: This is a light exaggeration of details based on video content.

: This is a more aggressive exaggeration of details based on video content.

You can use Starlight to render up to 5 minutes (9000 frames at 30fps) of footage.

Recommend using video at or under 1920x1080 resolution

The resolution will be based on the height, so if you have a 16:9 aspect ratio video, your output may result in 1920x

. If you have a 4:3 aspect ratio video, your video may result in 1620x

The resolution will be based on the height, so if you have a 16:9 aspect ratio video, your output may result in 3840x

. If you have a 4:3 aspect ratio video, your output video may be 2880x

Once you’ve decided on your model and resolution output, you can now 

: Gives a short duration so that you can see a sample of your outputs.

: Gives you the ability to chose the length of the duration up to the max 9000 frames.

While this is new for all and we continue exploring and refining Project Starlight, there are a few things to consider when using this new tool:

This AI model is both complex and resource heavy. Meaning, that it could take a while to render. This is why, Precise is currently only available via our cloud app, Astra.

For now, you can only render 9000 frames, which comes out to about 5 minutes of 30 FPS.

Recommended to use videos at or under 1920x1080 resolution.

The web input, however, only accepts H264 MP4 files.

Currently only exports 1080p and 4K, MP4 videos.

Renders will only be available for a max of 7 days.

Be sure to make a copy of your Cloud Render IDs. These may not always be recoverable.

Please note that if you have text that is too small, blurry or inconsistent, the result may not be "sp3ll3d" correctly. If you can barely make it out, so will the AI model. It may assume that the text is a texture or pattern.

If you have interlaced videos, it is recommended that you deinterlace first before enhancing.

Please note that free previews (a temporary promotion) is no longer available even if you have a Legacy version of Topaz Video AI.

Ultimately, we want you to have fun with Precise on Astra! This is a new horizon for everyone, and another great leap to learn and create for today and tomorrow!
