This balance is a rough estimate — the actual billed time is measured from the audio itself.

What would you like to do?
Welcome — let’s set you up
Before we can translate a video, we need to add your API keys. We’ll guide you step by step (no tech skills needed).
Just watching with a subtitle file you already have? That works right away, no setup needed — this is only for making new subtitles.
You must sign in to Google in order to use the Instant pipeline.
A quick heads-up
To land subtitles at nearly the same time as the speech, this page decodes your file and transcribes about 15 seconds ahead of the video while it plays. That background work uses some of your computer's processing power.
Upside: subtitles arrive on time, pausing is instant, and the timing features work here without a Premium purchase. Downside: some CPU use while watching, and minutes are billed at the usual rate.
The pipeline you're on can't tell speakers apart. Switch to Instant or ElevenLabs in Settings if you need this.
Which part should we translate?
Scrub to a moment, then pin it as the start or the end.
This file is too big to prepare up front. It will play through quietly while the subtitles are made instead — that takes as long as the part you select. Keep this tab open until it finishes.
Try a 2-minute sample first?
Pick any 2 minutes and we'll subtitle just that — billed as those minutes. Check the result and adjust before committing to the whole file.
Sample ready — check it below, then continue when you're happy.
