H.264 and H.265 (HEVC)

This guide discusses which iPhones are compatible with which settings.

NOTE: Also as of 3.5.9, all 4K footage is shot in HEVC. This will be fixed in a future update.

H.264

H.264 has been around since around 2014, and has been the standard for all HD recording and playback.

For iPhones 6s or newer, they support H.264, High Profile 5.1 with AAC-LC audio. A full list of all levels and what they support is available here.

FAQ

Q: Why am I seeing a blank video when playing it on my Mac / Windows machine?

A: On Mac it requires that you upgrade to High Sierra. On Windows it requires purchasing HEVC as a plug-in: Microsoft Store link

Q: I set the Moment app to H.264, but I can't see the video, or it is coming through as the wrong format. What's wrong?

A: If you recorded a video at a setting that H.264 does not support, we will force the video to be recorded in HEVC. Also as of 3.5.9, all 4k footage is shot in HEVC. This will be fixed in a future update.

Q: Why is my footage not playing back correctly in Adobe Premiere?

A: Make sure you are on the latest version of Adobe Premiere, and are using Mac OS Sierra or higher.
