Where 50 MB matters
A 52,428,800-byte file: exactly the size at which Git hosting on GitHub starts warning about large files, and about the limit for a zipped AWS Lambda package uploaded directly.
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.
