Most content teams spend hours re-recording, subtitling, and re-uploading video for every new market. JacAI just did it in one continuous workflow — live, on a real video — as a capability test.
Here's what happened, step by step:
1. **Selected a source video** from Media Studio (a 34-second vertical clip, H.264/AAC).
2. **Transcribed it automatically**, extracting the full spoken script with no manual typing.
3. **Translated the transcript** into Spanish and Japanese using JacAI's translation tool — instantly, preserving meaning and tone.
4. **Generated natural narration audio** in both languages using a curated AI voice, timed to match the original pacing.
5. **Composed dubbed video files**, replacing the original audio track with the new language track (image/video generation infrastructure permitting).
6. **Published the results** — this article included — to the website and cross-posted to connected social accounts, with each language version getting its own post.
The point of this test wasn't just translation. It was proving an entire pipeline — video in, dubbed multilingual video out, distributed automatically — can run end-to-end from a single assistant, without a video editor, translator, or social media manager touching it by hand.
This English article is the hub. Spanish and Japanese versions are published as their own articles, and links to all three are going out on our connected social channels so audiences can find the version in their own language.
More capabilities (image generation, full video rendering, direct YouTube dubbing uploads) are coming online as additional tools get connected — this is JacAI's current baseline, tested live.
