🧭 What happens during dubbing

The app follows a clear path:

1. It reads your uploaded audio or video
2. It finds the speech in the clip
3. It translates the spoken text
4. It generates new speech in the target language
5. It places the new speech in the same rough time slots as the original
6. It builds the final audio and video files for download

This helps the final dub stay close to the pace of the source clip.

🎬 Video and subtitle details

When you upload a video file, the app extracts the audio track first. It then sends that audio through the dubbing flow.

For the final video:

• the original video stays intact in the left panel
• the dubbed version plays with muted source audio
• subtitles can appear on top of the video
• the exported video uses WebM format
