Questions
Why won’t my iPhone video play on Windows at all?
Newer iPhones record in HEVC (H.265), which some Windows PCs can’t play without an extra codec. If the MP4 still won’t play, compress it in step 2: that re-saves it as H.264, which plays everywhere.
Can I make my iPhone record MP4-friendly video in the first place?
Yes: Settings, Camera, Formats, Most Compatible. Videos then use H.264, which Windows plays, though the files are larger.
