Spelo StudioYour team has the final word.
Spelo makes the dub. In the Studio your team reviews every line next to the picture, fixes what it wants and exports the finished video.
One scene, up to two minutes, in one target language.
Select a line
Each row shows the original and the dub, with the picture beside it.
Edit, then regenerate
Change the words, voice or emotion, and re-voice just that line in seconds.
Gold is original sound
The actors' own laughs and gasps are marked, so reviewers know they stay.
Translation and performance
Correct a line the way a dubbing director would: the words, the voice and how it is played.
Rewrite the translation
Type a better line, or ask for a fresh translation that reads the whole film's brief: who each character is and how they address each other.
Change the voice
Pick another voice for one line or for every line a character speaks, from the stock voices or a large library from ElevenLabs. Preview before you use it.
Direct the emotion
Leave it on Auto to follow how the original line was delivered, or set up to three words such as "whispering, scared".
Fix who says it
Move a line to a different character when two voices were confused.
Timing and sound
Every line sits on a timeline with the original voices, the background and the new mix as waveforms.
Start and end
Drag a line on the timeline, or trim either edge, to move it against the picture.
Speed
Leave speed on Auto or set it from 0.8× to 1.3× when a line has to fit a tight moment.
Line volume
Raise or lower a single line by up to 12 dB.
Background level
Set the music, effects and crowd for the whole film, from −20 dB to +10 dB.
Review and export
Your team owns the sign-off. The Studio makes it quick to check and finish a whole film.
Find what needs a look
Filter to changed lines or lines that need review, and jump to the next issue.
Drafts until you save
Edits stay drafts until you save, so a reviewer can try things without changing the dub.
Re-dub only what changed
Re-dubbing re-voices the lines you changed and reuses every other take.
Export the MP4
Download the finished video. Spelo asks first if saved changes haven't been dubbed yet.

Questions
Does our team need to know the AI side?
No. The Studio works like a script and a timeline: read the line, change it, listen, move on.
Who signs off the language?
Your team. Spelo makes the dub and the mix; your reviewers approve every line before export.
Can a dubbing studio use it for its own clients?
Yes. A licence lets your writers and directors use Spelo for the first pass and the Studio for the polish.
