Why not generate at 4K?
Veo prices every second of output and 4K costs more. Most takes get thrown away. Upscaling only the keepers on your own GPU pays the premium on none of them.
How it works
- Generate at 720p or 1080p
Iterate at the cheap size.
- Drop the keeper into Acuta
Any aspect ratio, at least 720 pixels on the short edge, up to 10 minutes. Check three frames at actual pixels first.
- Export 4K
Your graphics card does the work. The file lands on your disk.
Questions
- Is it free?
- Yes. The work runs on your own GPU, so there is nothing to meter.
- Is my clip uploaded?
- No. It is read from your disk, upscaled in the tab and written back.
- 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.
