🔍 How to upscale a video to 4K with AI
AI upscalers now match — and often beat — what dedicated hardware did five years ago. Here is how to push a 720p draft to a clean 4K master without the plastic look.
Upscale last, not first
Never upscale before the edit is locked. Every extra frame you throw away after upscaling is money burned. Iterate at the lowest resolution, colour-grade, cut, then upscale only the final timeline.
Pick the right upscaler
Topaz-style video upscalers are the professional standard for clean 4K and 60fps. They handle motion blur, chroma noise and compression far better than image-only upscalers stacked frame-by-frame.
Match the framerate to the content
Cinematic shots stay at 24fps for the film feel. Sports, gaming and vlogs benefit from 60fps interpolation. Don't push a 24fps hero shot to 60 — it will look like a soap opera.
Watch for the waxy-skin artefact
Aggressive upscalers can over-smooth faces. Lower the enhancement strength on close-ups, or upscale twice at moderate settings instead of once at maximum.
