1440p
Also known as: 2.7K, QHD
The 2560 by 1440 resolution, the middle step between 1080p and 4K that trades a little detail for considerably smaller files.

What it means
1440p sits between the two common choices. It carries roughly twice the pixels of 1080p (Full HD) and under half those of 4K video, which is a genuinely useful middle rather than a marketing number invented to sit between two others.
Action cameras offer it as a high frame rate option. Shooting 1440p at a rate 4K cannot sustain is the usual reason to choose it rather than any particular preference about resolution.
On GoPro bodies it has a particular history, because the taller sensor modes sit near this height and crop to it. The number is a sensor artefact as much as a standard.
How it works in practice
It is the frame rate choice in disguise. A High frame rate (HFR) clip for slow motion at 1440p is sharper than the same moment at 1080p and more sustainable than 4K is. The compromise is deliberate.
Delivery is still 1080p in most cases. Downscaling 1440p to a standard export produces a cleaner result than shooting 1080p directly, through simple Oversampling of the detail.
Card and heat demands fall with it. A lower Bitrate than 4K means longer recording before a camera overheats, which matters on a long session in the sun.
What to watch out for
It is an awkward intermediate for delivery. Platforms treat it as neither standard nor high resolution, and a 1440p upload is frequently recompressed as though it were 1080p anyway.
Mixing it with 4K in one timeline needs care. Scaling differences show at a cut, and Transcoding to one resolution before editing avoids a soft clip nobody notices until the export is finished and watched.
The crop factor can differ. A 1440p mode on a taller sensor is not the same field of view as 4K, so a Field of view (FOV) mismatch appears between clips of one session.
How RawClip handles it
Clips at mixed resolutions are handled together and the delivered sequence is rendered at one size, so a 1440p clip beside a 4K one needs no preparation. Higher resolution gives cropping and stabilisation more room to work with afterwards.
