Record at 4K — or 1080p when that is smarter
OneTake lets you pick the output height before you record: source, 4K, 1080p or 720p. It never upscales — a 1080p screen recorded at “4K” stays 1080p, because inventing pixels does not make text sharper.

- Set resolution in the Output panel“Source” keeps whatever the screen gives you; 4K/1080p/720p cap it.
- Pick 30 or 60 fps60 fps doubles the bitrate and the CPU cost; use it for motion, not for slides.
- Start recordingThe panel shows the real output size before you commit.
- Export MP4H.264 is the default; WebM and GIF are available too.
What “4K” actually means here
It is a target height of 2160 px. If your screen is 3840×2160 and you choose 4K, you get 3840×2160. If your screen is 1920×1080, choosing 4K changes nothing — and the UI tells you the real size rather than pretending.
The same applies to camera picture-in-picture: the composite canvas is sized from the real source, then scaled to your target.
4K needs headroom
4K at 30 fps with a camera overlay is roughly four times the pixel work of 1080p. On integrated graphics the compositor can fall behind and the result looks choppy; dropping to 1080p usually fixes it completely.
Bitrate matters as much as resolution: 1080p at 10 Mbps looks sharper on text than 4K at 4 Mbps.
Frequently asked questions
Can I record 4K at 60 fps?
Only if your machine and browser can keep up. Start at 30 fps; raise it if the frame counter in the strip stays at the target.
Does it upscale a 1080p screen to 4K?
No, and it never claims to. The output is capped at the source size.
How big is a 4K recording?
Roughly 1.2 GB per 15 minutes at 10 Mbps. The transport bar shows a live estimate while recording.
Which format should I pick for 4K?
MP4 (H.264) — it is the default and plays everywhere.
