🚀

Enterprise translation

Translate subtitles into an available target language, then review the result.

ASS preserves supported fonts, colors and positioning for styled subtitles. SRT is a text-and-timing format; ASS is not a finished MP4.

🔒

Privacy-focused

Your files are processed securely. For subtitle translations, local models are used where available; otherwise subtitle text may be processed through the Google Translate API.

Do not settle for boring subtitles.

🎙️ Voiceover (AI)

Voice library & multilingual support

Choose from the voices and languages available in the voiceover workflow.

Timing from subtitles & speaker assignment

Use subtitle start and end times to prepare the voiceover, then review its timing with the video.

Fine-tune speed & pitch

Adjust the available voice, speed and pitch settings.

Export: audio track & finished video

Export as a separate audio track — or directly as a rendered video with voiceover.

Review voiceover text

Correct names and technical terms in the subtitle text before generating the voiceover.

Noise reduction and leveling — for clean, clear output.

Subtitle export options

Available exports depend on the editor and project type. Burn-in requires a video; a subtitle document alone does not contain a media track.

.srt .ass .vtt .txt .mp4 (burned in) .sbv DOCX JSON CSV HTML

In Studio, media projects and timed subtitle documents can also be exported as DOCX, JSON, CSV and HTML transcripts, without Ultimate. TXT drafts require confirmation of the suggested timings first.
