How to Use Upscale Video to 4K
- Upload your video, image, or GIF file
- Choose 2x or 4x upscale factor
- Select an AI model — Fast for most content, Quality for maximum detail, Anime for cartoon/anime
- Click Process — parallel GPU processing handles video quickly
- Download the upscaled result
Features
- AI-powered 4x upscaling — 720p to near-4K, 1080p to 4K+
- 3 AI models: Fast, Quality (HAT), and Anime-optimized
- Parallel GPU processing for fast results
Frequently Asked Questions
- What's the difference between the AI models?
- Fast (Real-ESRGAN) offers the best speed-to-quality ratio for general content. Quality (HAT) 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 (HAT) 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.
