Where 100 KB matters
A 102,400-byte file that sits exactly on the default request-body limit of Express. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Express body parsers | 100 KB (102,400 bytes) by default | A request body of exactly this size passes; anything larger returns 413 Payload Too Large. |
| Gmail message clipping | About 102 KB of HTML | Longer messages are truncated behind a "view entire message" link. |
| Amazon DynamoDB items | 400 KB per item | 100 KB fits; the 500 KB sample does not. |

Testing notes for SRT
- Files saved in a legacy encoding show garbled accents; importers should detect or require UTF-8.
- SRT uses a comma before the milliseconds and WebVTT uses a full stop. Mixing them up is the usual reason a converted file fails.
