Sharpen, upscale, and restore photos with precision.
4K Video Upscaler
Transform your videos to stunning 4K Ultra HD. Our AI doesn't just enlarge—it intelligently reconstructs detail for genuinely sharper footage.
4K Upscaling Features
True 4K Resolution
Output genuine 3840×2160 (4K UHD) or 4096×2160 (DCI 4K). Perfect for YouTube 4K, large displays, and professional delivery.
Preserve Motion Quality
Temporal algorithms ensure smooth motion without artifacts. Fast action scenes stay crisp; slow pans remain buttery smooth.
AI Detail Synthesis
Our neural networks don't just stretch pixels—they generate new detail based on patterns learned from millions of 4K videos. The result looks like native 4K, not upscaled.
HDR-Ready Output
Upscale while maintaining color accuracy. Compatible with SDR and HDR workflows for modern display requirements.
When You Need 4K Upscaling
YouTube 4K Content
YouTube prioritizes 4K videos in search and recommendations. Upscale your 1080p archive to reach the growing 4K audience.
Large Screen Display
Videos on 4K TVs and monitors need 4K source material. Upscale presentations, digital signage, and home theater content.
Future-Proofing Archives
Convert valuable footage to 4K now. As displays continue to improve, your content stays relevant and viewable at full quality.
How to Upscale Video to 4K
Upload Your Video
Upload 720p, 1080p, or lower resolution footage. We accept MP4, MOV, AVI, and most video formats.
AI Processes to 4K
Our neural networks analyze each frame and synthesize new detail. Processing time varies by length—typically 5-20 minutes.
Download in 4K
Preview the 4K result and download when satisfied. Export in H.264, H.265/HEVC, or ProRes-compatible formats.
Frequently Asked Questions
What's the best source resolution for 4K upscaling?
1080p gives excellent 4K results—it's a 2x upscale. 720p works well too. Lower resolutions (480p, SD) benefit from our upscaling but may show more visible enhancement.
Will 4K upscaling make my video look artificial?
No. Our AI is specifically trained to generate natural-looking detail. Results appear as native 4K, not processed or "AI-looking."
How long does 4K upscaling take?
Expect 10-30 minutes for a typical 3-5 minute video. 4K processing is more intensive than lower resolutions due to the four times more pixels.
What 4K format options are available?
We output 4K UHD (3840×2160) by default. DCI 4K (4096×2160) available on request. Codec options include H.264, H.265/HEVC, and VP9.
Can I upscale 4K to 8K?
Currently we support up to 4K output. 8K upscaling may be available in the future as display technology continues to evolve.
Does upscaling improve video quality beyond resolution?
Yes! Our 4K upscaling also reduces noise, sharpens detail, and can improve color accuracy—it's a complete quality enhancement, not just bigger pixels.
