Where 15 MB matters
A 15,728,640-byte file, 15 MB in the binary units that operating systems and upload limits use. It is useful wherever a form, an API gateway, a storage quota or a mail server is configured with a limit of about this size.
Use this file for
- Testing image resizing and memory use
- Verifying that an allow-list accepts video/quicktime
- Testing thumbnail and duration extraction
Testing notes for MOV
- Browser playback is uneven. Safari plays MOV; other browsers depend on the codec inside and on how the server labels the file. Convert to MP4 for anything shown on a web page.
- Phone footage stores its orientation as a rotation flag instead of rotating the pixels. A pipeline that ignores the flag produces sideways video.
