Filmhub caption checker

Check your SRT captions against Filmhub’s published caption rules before you upload. Every finding quotes the rule it comes from.

Your file never leaves your computer. The check runs in your browser, and this page can’t send anything anywhere.

What this check can’t tell you

Sync with the dialogue. We never see or hear your film, so we can’t tell whether each caption appears when the words are spoken. Filmhub checks that captions are within half a second.
Word-for-word accuracy, spelling and punctuation. Filmhub reviews these by hand.
Other platforms’ rules. This checks Filmhub’s rules only.

Passing this check doesn’t guarantee Filmhub will accept your captions.
