Handling verdict

A binary payload has no character encoding. A charset parameter here is meaningless and occasionally confuses strict parsers.
The format compresses internally. Another transport encoding costs CPU on both ends and typically changes the size by less than a percent — sometimes upward.
Registered with IANA through a public review process, so the name is stable and every implementation can rely on it meaning the same thing.
Anatomy of the name

Subtype

Registered in the standards tree.
Structured syntax
none
No suffix, so the payload format is defined entirely by the subtype itself.
Parameters
none
Beyond the charset rule above, this type defines no parameters of its own.
What trips people up
1 note- Structurally close to MP4, so many .mov files play in browsers — but not reliably enough to depend on.
Response headers
Content-Type: video/quicktime
X-Content-Type-Options: nosniff
Content-Disposition: inlinenosniff stops the browser second-guessing the type you declared, which is what makes the rest of this reliable. Serving it inline is safe here because the browser renders it without granting it script access.

Check these bytes rather than the client-supplied Content-Type when validating an upload. The header is a claim; the signature is evidence.
