1Tools with the same reading

Descript, fal, Google Veo, Higgsfield, invideo, Kapwing, Luma, Pika, Revid and VEED also document “4K”, which makes 11 tools with this reading.

It reflects the documentation on the reading day.

2Why it matters in a pipeline

A resolution claim is only as useful as its conditions. Several apply to one model, one plan or one length, and 4K for images says nothing about video.
