Translate Video to 100%
Open a YouTube video with accessible captions, choose the target language, and press Translate Video. Progressive Final rebuilds fragmented captions, translates finished blocks with context, and continues in the background until 100% even if you move to another tab.
Choose Gemini models with quota in mind
Use a model available to your Google AI Studio project and switch models when one reaches a temporary quota limit. Free-model capacity can vary by account and day, so reuse completed translations and avoid duplicate jobs for the same video.
Know what each status means
Mono distinguishes loading, translating, saving, saved, sync errors, and retry states instead of showing false success. If a server save has not been confirmed, the browser copy remains safe and the interface asks you to retry.
