Dubbing script checklist

Decide three things before you upload: which languages, whether the picture should change, and who has to sign off.

• Languages. Sonilo translates into 24 languages, including both Spanish for Spain and Latin American Spanish, and Portuguese for Portugal and Brazil. Each language is its own dub.
• Lip sync. With lip sync on, the speaker's mouth is matched to the new language. Turn it off to keep the original picture and replace only the voice.
• Review. If someone has to approve the wording, plan for Proofread first or an uploaded script, not a fix after the dub.

• Length: up to 5 minutes per video. Split a longer video at a natural pause and translate the parts.
• File: MP4, MOV or M4V, up to 400 MB, between 360 by 360 and 4096 by 4096 pixels.
• Sound: the video has to have speech in it; a silent clip is turned away. For a silent video, write a voiceover instead.
• Clean speech: music or crowd noise under the voice makes the transcript worse, and every later step starts from the transcript. Use the cleanest mix you have.

1. One speaker per line. A line that starts with one person and ends with another gets one voice. Break it where the speaker changes.
2. Short sentences. A dub has to fit the time the original took. Many languages run longer than English for the same meaning, so a sentence that is already fast in the source will be rushed or shortened in translation.
3. Finish the thought inside the line. A sentence split across two lines can be translated as two fragments.
4. Cut filler you would not want translated. Repeated words, false starts and "you know" get voiced like everything else.

If you already have approved translations, upload one .srt or .vtt file per language (up to 1 MB each), and the translation will say exactly those lines. It is all languages or none: one file for every language you picked. An uploaded script can't be combined with Proofread first, and it is not available for a batch of videos.

Check each file before you upload it:

• Cue numbers run in order, and every cue has a start and end time in the form 00:00:01,000 --> 00:00:03,500 (SRT) or 00:00:01.000 --> 00:00:03.500 (WebVTT).
• Cue times match the source speech, so each translated line is said when the original was.
• The file is saved as UTF-8, so accents and non Latin scripts survive.

Proofread first transcribes and translates the video, then opens the translation for you to edit before anything is voiced. The proofread itself is free; credits are used only when you translate the video. In the proofread view you can:

• Fix the original line. Every language's translation is redone from your correction.
• Remove a line. It won't be translated, voiced or subtitled; the video itself is not cut.
• Name the speakers and change who says a line.
• Save a draft and come back to it.

A line too long to say in its time is shortened, so this is also where to trim a long sentence yourself, in words you chose.

• Subtitles: the subtitle editor lets you edit lines, pick a style and export the video with the subtitles burned in. Burning them in is free, and the original dub stays available.
• Music: the dub keeps the original music and effects under the new voice. To replace the music, Add new music (on a paid plan) sends the dub to Video to Music and keeps the translated voice.
• Downloads: a Free account can create and preview a dub; downloading the video, audio or subtitles needs a paid plan.
