Your iPhone recorded a video. It's a MOV file. Your Windows PC has opinions about that. MOV is Apple's video container, technically excellent — it supports high-quality codecs including H.264, H.265, and ProRes (the standard for professional video editing). On macOS and iOS, everything plays seamlessly.
The problem is cross-platform compatibility. On Windows, MOV support is inconsistent. Some files play fine in Windows Media Player; others throw codec errors that make no sense. The issue is usually the codec inside the container, not the container itself — a MOV with H.264 plays almost everywhere, but a MOV with ProRes or HEVC may need additional codecs. iPhone videos also tend to be large because iOS encodes at high bitrates for maximum quality.
VLC plays every MOV file without complaint. QuickTime Player (macOS) handles them natively. For sharing across platforms, converting to MP4 with fwip solves almost every compatibility issue while preserving quality. The video data stays the same — you're just changing the container to one that Windows and Android expect.
