How to Install Topaz Video AI and Upscale Your First Clip

2026-09-02 · SoftVault team

Set up the app and its model cache, choose the right enhancement model and export a clean 4K result without the plastic look.

Topaz Video AI upscales and restores footage using GPU-trained models. Installation is quick, but the model download on first use is not, and the wrong model turns a sharp clip into something plastic. This guide covers the setup and a sensible first project.

Requirements

Windows 10 or 11 64-bit is required. The real constraint is the GPU: 8 GB of VRAM is the comfortable baseline for 1080p to 4K upscaling, and 12 GB or more for 4K input. Budget about 100 GB of free space, because models, previews and temporary files are large and the app always writes new files instead of touching the originals.

Installation

  1. Unpack the archive and run the installer as administrator.
  2. Choose a drive with room for the model cache, not just for the program.
  3. Finish the install and launch the application.
  4. Sign in and enter the licence key from your package if activation is requested.
  5. In preferences, confirm the correct GPU is selected and enable model caching.

Your first project

  1. Drop a clip into the window. Keep the first test short, ten seconds is plenty.
  2. Set the output resolution, for example from 1080p to 4K.
  3. Pick a model: a general upscale model for clean footage, an enhancement model for noisy or heavily compressed source, and an interpolation model only if you also want more frames per second.
  4. Add a small amount of grain or noise suppression instead of stacking several models.
  5. Render a preview over a marked range and compare it against the original.
  6. Export with a high-quality codec such as ProRes or a high-bitrate H.264 profile.

Working fast

Every model change triggers a fresh preview render, so settle on your settings before committing to an export. Process long clips overnight: a full 4K export can take several times the clip length. Keep the source file on an SSD, since the app reads it repeatedly, and clear the temp folder between large jobs.

Avoiding the artificial look

If faces come out waxy, reduce the enhancement strength and re-render the preview. The gap between a good result and an obviously processed one is usually a single slider, so always compare a short preview before exporting the whole clip.
