Where 3 MB matters
A 3,145,728-byte file, 3 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
- Finding the first upload limit in a new stack
- Testing video uploads from iPhones and cameras
- Checking transcoding of MOV to MP4 for web playback
Testing notes for MOV
- Phone footage stores its orientation as a rotation flag instead of rotating the pixels. A pipeline that ignores the flag produces sideways video.
- Phones upload MOV by default, so an allow-list that names only video/mp4 rejects the most common video a mobile user has.
