YouTube creators and VTubers
Add a second language track to a video you already published. YouTube supports more than one audio track on the same video.
JoLoCity Dubbing
A new language track that still sounds like a performance.
We transcribe your dialogue, translate it with the scene and the emotion in mind, and voice it so the lines land on time. A tone dial lets you push a project slightly lighter, or slightly darker. Work runs on JoLoCity hardware, so your footage never goes to a third-party AI cloud.
English, Spanish (including Latin American Spanish), and Japanese to start. Pricing is per finished minute — ask us for a quote.
How it works
Four steps, from the files you already have to a finished audio track you can add to your video.
-
Send the picture
Share the video, and a subtitle file if you have one. We only take on work you own or have the rights to dub.
-
Transcribe and translate
We transcribe the dialogue, then translate it with scene and emotion in mind — not line by line in a vacuum.
-
Perform the lines
Expressive voice models can whisper, shout, or sound cheeky. We match the timing to the original so the new track sits on the picture.
-
Get a new audio track
You receive finished audio ready to add to the video. YouTube already lets one video carry more than one language track.
The tone dial
Every project gets a dial. Leave it in the middle and we follow the scene. Ease it toward lighter for a touch of humor. Ease it toward darker when the story should feel more dramatic, or a little more like horror. You set the direction; we keep it consistent from the first line to the last.
As written — we follow the scene's own tone.
- Lighter Slight humor, a warmer read.
- As written We follow the scene's own tone.
- Darker More drama, or a turn toward horror.
This slider is only a demonstration. The setting for your project is agreed when we start work.
Who it's for
People and small studios who own their content and want it in another language, without a full recording studio.
Indie animation studios
Release a short or a series in English, Spanish, or Japanese without hiring a full voice cast for every language.
Game cutscenes
Give players a localized track for cinematics and story scenes, timed to the original edit.
Film, courses, and documentaries
Small distributors and educators who want another language on a film, a lesson, or a documentary they already own.
Why JoLoCity
The difference is the performance, where the files stay, and a process we can time on our own machine.
Performance
The voice can whisper, shout, or sound cheeky, instead of reading every line the same way. Timing is matched to the original lines so the new track holds the picture.
Privacy
Processing runs on JoLoCity's own hardware. Your footage is not sent to a third-party AI cloud to be transcribed, translated, or voiced.
Turnaround
We run the work on a dedicated machine and time each stage, so you get a clear picture of how long your project will take before we start.
A sample, soon
A short public demo will live here, made from footage we have the rights to use.
Sample
Demo coming soon
We won't put a stand-in clip here. When the demo is ready, you'll be able to hear the tone dial and the timing match on real picture. Until then, request a quote and we can talk through a private sample on material you own.
Questions
What are you allowed to dub?
Only content you own, or content you have the rights to dub. We do not take on someone else's film, series, or channel without that permission. If you're unsure, ask before you send files.
Which languages do you offer?
We start with English, Spanish (including Latin American Spanish), and Japanese, in either direction. If you need another language pair, mention it in your quote request and we'll tell you whether we can take it on.
How do you charge?
Per finished minute of audio. Request a quote with a rough runtime, the languages, and the kind of content, and we'll come back with a number. We don't publish a rate card yet.
Where does my footage go?
Onto JoLoCity's own machines. It is not uploaded to a third-party AI cloud to be processed. We'll agree on how you send the files before work starts.
Can I add the dub to a YouTube video?
Yes. YouTube lets one video carry more than one audio track, so a viewer can pick the language. The same idea works for any player or store that accepts an alternate audio track.
Do I need subtitles already?
They help if you have them, but they're not required. We can transcribe from the audio. If you already have a subtitle file in the source language, send it with the video.
Can I hear a demo first?
A public demo is coming. For a private listen, send a short clip you have the rights to when you request a quote, and we'll talk it through.
How do I start?
