Four steps. You are in the loop for all of them.

1. 

   Upload and choose

   Sign in, press Start dubbing and drop in your video. MP4, MOV, MKV and WebM all work. The form tells you the largest file it accepts.

   • Choose the language of the video, or leave it on auto-detect, and the language to dub into.
   • Dublio reads the length of your video in the browser and shows what the dub will use and what you will have left, before anything is sent.
   • To dub only a section, fill in a start and an end time.
   • Pick a voice and press Hear to listen to it in your language. Write instructions for the tone if you want: formal or casual, names to keep, words to avoid.
   • Confirm that the video is yours or that you have permission to dub it.

   While you wait, Dublio extracts the audio, writes out what is said, and translates the whole script in one go. You can leave the page. Progress is saved in your project, and you can press Stop at any time.

2. 

   Review the script

   This is the step most tools skip. The translation appears next to the original, line by line, with the timing. Nothing has been voiced yet.

   • Press play on any line to hear it with the chosen voice.
   • Edit a line by hand. It is marked as changed.
   • Press the circular arrow to translate a single line again.
   • Change the instructions and translate the whole script again if the tone is off. This replaces your manual edits, so it asks first, and each project allows two.

   Read it aloud if you can. Check names, numbers and terms. A few minutes here saves a lot of fixing later.

3. 

   Generate the voice

   Press Generate. Dublio groups lines into sentences so each one is voiced as a whole, then fits the speech into the time of the original.

   • When a sentence is too long for its slot, Dublio shortens it once. If it still does not fit, the voice is sped up slightly. Adjusted lines are tagged in the script and shown on the timeline.
   • Choose whether to keep the original sound quietly under the dub or remove it. Add a background music track if you like and hear a 14-second preview of the mix.
   • In the Subtitles and Brand tabs, set burned-in subtitles, a logo, corner text or title cards. These only change the export, so you can adjust them afterwards for free.

   If one line sounds wrong, change that line and generate again. Only the changed part is voiced again.

4. 

   Download

   You get four files from one project: the dubbed video, an SRT subtitle file, a dub-only MP3 and a podcast-style audio file. You can also take all of them in one zip.

   • Edit a line, change the subtitles or swap the logo, then press Re-export. It reuses the voice track and costs no minutes.
   • Choose the video size when you export: Original, High, Medium or Small.
   • Projects are kept for 14 days after you last used them, or 30 days once you have bought minutes. Download what you need before then.

What it costs, in one line.

A dub uses the length of the video in minutes. You get 10 free minutes every month. Editing, voicing the changes again and re-exporting are free. See the packs and the calculator.
