Why not generate at 4K?
AI video tools generate at 720p or 1080p and charge more for 4K on every take. Upscale the one take you keep instead, on your own GPU, and upload that.
How it works
- Generate at 720p or 1080p
In Veo, Flow, Kling or Runway.
- Upscale the keeper to 4K
Up to 10 minutes, at least 720 pixels on the short edge. Check three frames at actual pixels first.
- Upload the 4K file
YouTube gives it the higher-quality encode.
Questions
- What about ads and social?
- Paid placements top out at 1080p. Acuta’s presets cover both: 4K for YouTube and TV, 1080p class for social, vertical staying vertical.
- Is my clip uploaded to Acuta?
- No. It is upscaled on your own graphics card and written to your disk. You upload the result to YouTube yourself.
- How long does it take?
- A 30-second export takes at least 2½ minutes on an M3 Max, plugged in, a floor, not a promise. Plug in: on battery, Apple silicon runs roughly an order of magnitude slower.
- How good is it?
- It slightly over-sharpens the mid-tones on video, by 8–10%. That was measured, never resolved, and not investigated, and it can read as a synthetic crispness on skin and on gradients when you look closely on a big display.
