  2. Choose 2x or 4x upscale factor
  3. Select an AI model — Fast for most content, Quality for maximum detail, Anime for cartoon/anime
  4. Click Process — parallel GPU processing handles video quickly
  5. Download the upscaled result

Features

  • AI-powered 4x upscaling — 720p to near-4K, 1080p to 4K+
  • 3 AI models: Fast, Quality (our high-quality AI), and Anime-optimized
  • Parallel GPU processing for fast results

Frequently Asked Questions

Is video upscale free?
No — AI video upscale is a Pro feature because each minute of video takes ~1 hour of GPU time on our current hardware. Image upscaling stays free for everyone at Upscale Image. We plan to bring video upscale back to free tier once we upgrade GPUs.
What's the difference between the AI models?
Fast (our AI upscaler) offers the best speed-to-quality ratio for general content. Quality (our high-quality AI) uses a transformer architecture for the sharpest possible details but is 3-5x slower. Anime is specifically trained on anime/cartoon content for the best results on that style.
Can I upscale 720p to 4K?
Yes! Use 4x scale to go from 720p (1280x720) to near-4K (5120x2880). For 1080p to 4K, use 2x scale.
How long does video upscaling take?
With parallel GPU processing, a 1-minute 720p video takes about 5-10 minutes depending on the model. Quality (our high-quality AI) is 3-5x slower than Fast.
Will upscaling add real detail?
AI upscaling generates plausible detail that wasn't in the original — edges become sharper, textures more defined. It's not magic, but results are dramatically better than simple bicubic scaling.
How does this compare to Topaz Video AI?
Topaz Video AI is the gold standard for offline desktop upscaling — if you have a beefy GPU and budget for the $299 license, Topaz still edges ahead on archival footage. For short clips and 95% of social media content, this tool gives comparable results, runs in your browser, and is comparable in quality. No 100GB download, no install.
