How 4K works here
Videos are created at 720p and then enhanced to 4K Ultra HD. We say this plainly because it matters: the 4K comes from enhancement, which adds sharpness and cleans the picture, and it cannot invent detail that was never there. For most scenes the result is clearly crisper than Full HD on a large display.
When 4K is worth the extra credits
- Playback on a TV, a projector or a large monitor
- Footage you will crop, zoom or colour-grade in an editor
- Work for clients who ask for 4K delivery
When Full HD is enough
For a phone or a social feed, Full HD looks the same to most viewers and costs half as much.
