How to record videos in MP4 format in iPhone 16 pro Max?

The iPhone 16 Pro Max automatically records videos in MP4 format (H.264 codec) or HEVC format, depending on the settings.

HEVC (High Efficiency) format is more storage-efficient but is saved in an .MOV file. If you’re recording videos with High Efficiency selected, you may need to convert the file later to MP4 using a video converter app.

Settings->Camera->Formats->Select Most Compatible

Settings->Camera->Record Video->Select 4K and fps

MP4 is the container and H.264 is the CODEC. The CODEC must be inside a container.

If the encoded formats are not MP4 then they are likely MOV, but could be AVI or MKV. You’ll need to use software to convert MOV to MP4.
