Where 10 MB matters

A 10,485,760-byte file: over the default limits of PHP, API Gateway and Spring Boot requests. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Amazon API Gateway	10 MB payload	A 10 MB file in a multipart or base64 body is over the limit.
Spring Boot multipart	10 MB per request by default (max-request-size)	Exceeded once form overhead is added.
PHP	8 MB POST body by default (post_max_size)	Rejected before the script runs.
Amazon S3 multipart upload	5 MiB minimum part size	This file splits into exactly two minimum-sized parts.
Email attachments	Commonly 20 to 25 MB per message	10 MB fits, at about 13.3 MB once encoded.

Checking HTML video playback and seeking
Testing range-request support on servers and CDNs

Testing notes for MP4

Seeking in a browser needs HTTP range requests. A server that ignores the Range header makes video appear to work until someone drags the progress bar.
A valid .mp4 may contain a codec the browser cannot play; container and codec are separate questions.
