Where each tool fits
Choose FrameScale AI if you want a free tool, open-source code you can inspect and modify, Linux support, or full control over which open models process your footage. Its models are widely used, well-documented open research models.
A commercial suite may suit you better if you rely on its own proprietary models, plug-ins for editing software, or paid support. Both kinds of tools run locally on your GPU.
Switching in three steps
- Install FrameScale AI. Download the installer for Windows, macOS or Linux from the download section and install it. It is free, needs no account, and runs entirely on your computer.
- Rebuild your usual pipeline. Turn on the stages you used before: Upscale for enhancement, Denoise for noise, Face Fix for faces and Interpolate for frame-rate conversion.
- Compare on your own footage. Use Render 2 s to preview the exact result on a short section and compare it side by side with the original before rendering the whole video.
Step-by-step guides for the common jobs: upscale video to 4K, restore VHS tapes and convert video to 60 fps.
