Topaz Labs - How To Enhance Low Quality Videos

Bringing old, low-resolution videos to life was impossible until Topaz Labs Video AI made it a piece of cake. With advanced AI models, Topaz allows you to upscale, denoise, and refine videos to achieve impressive results. Let's explore how to transform a 320x240 pixel video into a crisp and high-resolution one by upscaling it 4x while addressing common artifacts and imperfections!

Step 1: Setting the Stage.

Low-quality videos, such as those captured on early mobile phones or VHS tapes, present unique challenges. Topaz Labs Video AI simplifies the process with various AI models designed for different video types.

Eample Project.
A segment from the classic film The Scarlet Pimpernel was chosen for this tutorial. The goal? Transform a compressed, low-resolution clip into a clear and visually appealing video.

Step 2: Choosing the Right AI Model.

Topaz Labs offers various AI models tailored for specific use cases. For this project, the Nyx AI model was selected, as it excels at enhancing older films and VHS footage by flattening compression artifacts while preserving sharp edges and fine details.

3. Settings Overview.
Create a cylindrical object to represent the vine’s body. Apply the Path Deform Modifier to align it with the control spline. Enable Auto Stretch for dynamic length adjustments. Reduce geometry complexity by optimizing segments to balance detail and performance.
  • Upscale Factor: 4x (from 320x240 to 1280x960).
  • Recover Detail: Set to zero to avoid retaining original compression artifacts.
  • Model Variant: Nyx for optimal balance; Nyx Fast is available for quicker but slightly less refined results.

Step 3: Fine-Tuning the Enhancement.

The tutorial highlights the importance of adjusting parameters for optimal results.

  • Sharpening: Increases clarity by refining edges.
  • Dehaloing: Removes halos around sharpened edges, common in older video formats.
  • Noise Reduction: Balances compression removal while adding a touch of grain to maintain a natural texture.

Step 4: Adding a Second Enhancement.

The software also allows users to stack enhancements for even finer control.

  • The Theia AI model was applied as a secondary enhancement, adding subtle sharpening and compression fixes.
  • A small amount of artificial noise was reintroduced to eliminate the flatness caused by compression removal, resulting in a more organic and visually appealing output.
Results: Before and After
The transformation is striking. Compression artifacts, soft edges, and pixelation plagued the low-quality original. After applying the enhancements, the video boasts sharp details, smooth edges, and balanced textures. Whether for nostalgic purposes or professional projects, Topaz Labs Video AI proves its value.

Key Takeaways.

  • AI Models for Specific Needs: Experiment with different models to suit your footage.
  • Fine-Tune for Perfection: Adjust parameters like sharpening and noise to get the best results.
  • Multi-Enhancement Workflow: Combining enhancements maximizes the potential of your video.

Conclusion.

Topaz Labs Video AI is a game-changer for anyone looking to breathe new life into low-resolution footage. Its intuitive interface and powerful tools make video enhancement accessible to both professionals and hobbyists, and we overall consider it a value-for-money solution, probably on of the best related to upscaling videos.
