Upscale Any Video to 4K.
Most AI models output 720p–1080p; screens are 4K. This three-minute walkthrough covers the finishing step that makes every clip look professionally delivered.
Walkthrough
Step by step.
Pick the final cut
Upscale last, after trimming, extending, and scoring. Enhancing footage you'll re-edit wastes credits.
Open the upscaler
From any clip's result screen, choose Upscale — or import phone footage and old videos from your library.
Choose the target
4K for publishing and TV playback; 2× for quick social posts. Moderate enhancement strength preserves the natural look.
Compare before exporting
Use the side-by-side preview — check faces and any text in frame, the two places over-sharpening shows first.
Export watermark-free
Save in your aspect ratio. The 4K master downscales beautifully to every platform.
Pro tips
Small moves, big difference.
Upscale is the last step
Always finish editing first — enhancement locks in whatever it's given.
Check faces at 100%
Zoom the preview to full size on a face; if skin looks waxy, lower the strength.
Queue and continue
Upscales run in the background — keep generating while they process.
Works on photos too
The same pipeline sharpens AI art and old photos to 4K.
FAQ
Quick answers.
Does upscaling actually add detail?
Yes — AI upscaling reconstructs plausible real detail (edges, texture, hair) learned from millions of frames. It's restoration, not stretching.
Can I upscale non-AI videos?
Yes. Phone footage, old family videos, and compressed downloads all benefit — often more visibly than AI generations.
What resolution can I reach?
Up to 4K output, from sources as low as 480p. Extremely low-quality sources benefit from moderate targets like 2×.
