Product Introduction

1. Astra from Topaz Labs is a web-based AI video upscaling tool designed to enhance AI-generated videos by increasing their resolution to 4K while improving visual quality and refining details. It leverages advanced Starlight models to deliver creative and precise enhancements for video content. The tool focuses on empowering creators during the final stages of their workflow to achieve professional-grade output.

2. The core value of Astra lies in its ability to transform low-resolution or artifact-heavy AI-generated videos into crisp, high-fidelity 4K content while preserving or reimagining details. It bridges the gap between raw AI-generated footage and production-ready quality, enabling creators to meet professional standards without compromising creative intent.

Main Features

1. Creative Upscaling: Astra’s creative mode uses generative AI to reimagine and enhance details in videos, offering adjustable strength settings (subtle or bold) to balance fidelity with artistic interpretation. This mode is ideal for adding texture, depth, or stylistic elements to AI-generated content.
2. Precise Upscaling: In precise mode, Astra upscales videos while maintaining the original structure and minimizing alterations, making it suitable for restoration or sharpening existing details without introducing artificial elements. This mode prioritizes accuracy for technical workflows.
3. Frame Interpolation: The tool allows users to increase frame rates up to 120fps or apply slow-motion effects (up to 8x) using generative AI to synthesize intermediate frames. This feature enhances motion smoothness and enables creative pacing adjustments for dynamic scenes.

Problems Solved

1. Astra addresses the challenge of low-resolution, blurry, or artifact-laden outputs common in AI-generated video workflows, which often lack the sharpness and detail required for professional use.
2. The product targets storytellers, video editors, and digital artists who work with AI-generated footage and need to refine it for platforms requiring 4K resolution, such as film, advertising, or social media.
3. Typical use cases include upscaling AI-animated shorts, restoring grainy synthetic footage, converting 1080p AI renders to 4K for commercial projects, or adding slow-motion effects to AI-generated action sequences.

Unique Advantages

1. Unlike traditional upscalers, Astra offers dual processing modes (creative and precise) tailored for AI-generated content, enabling both artistic enhancement and technical restoration in one tool.
2. Its Starlight models integrate generative AI for detail synthesis and frame interpolation, surpassing conventional interpolation methods by reducing motion artifacts and improving temporal consistency.
3. As a web app, Astra provides immediate access without hardware limitations, supports batch processing for large projects, and iterates rapidly through early user feedback during its development phase.

Frequently Asked Questions (FAQ)

1. What resolution inputs does Astra support? Astra accepts common video resolutions up to 1080p and outputs upscaled 4K videos, optimizing both AI-generated and traditionally recorded footage.
2. How does creative mode differ from precise mode? Creative mode generates new details and textures using AI, while precise mode focuses on sharpening existing elements without altering the original content’s structure.
3. Can Astra adjust frame rates for non-AI videos? Yes, the frame interpolation feature works on any video, allowing users to convert standard 24fps or 30fps footage to higher frame rates (up to 120fps) or apply slow-motion effects.
4. Is there a limit to video length for processing? During early access, Astra may impose temporary limits on video duration, but these will be expanded based on user feedback and server capacity upgrades.
5. How does Astra handle color consistency in creative mode? The Starlight models include color stabilization algorithms to maintain tonal coherence across frames, even when adding generative details.
