Camera and clip
Exporting slow motion
Getting the clip off the phone can silently throw away frames. On iPhone, AirDrop keeps the full 240 fps; dragging out of Photos on a Mac drops it to 120; File ▸ Export bakes it down to 30. Samsung saves a 5-second 240 fps capture as a 40-second 30 fps file with nothing in it to say so. Whatever you do, the app measures the file's real playback rate on load and shows it — check it against what you set here.
