SoulDub is a browser-based video translation tool. You upload an MP4 and pick source and target languages. It then detects speech, transcribes and translates it, and generates subtitles plus AI voice-over. You review each segment in a subtitle editor, fix text or timing, regenerate voice for changed lines, and export the video, SRT files, or audio tracks. It fits creators, marketers, and teams localizing video, and its API and AI Agent Skill let you automate the work.

• Automatic Speech Translation: SoulDub pulls speech out of your video, transcribes it, and translates it into your target language. You don't have to prepare a script first.
• AI Dubbing: It generates voice-over in the target language, and you review it segment by segment before you export.
• Subtitle Editor with Timeline: You edit source and translated text, fix terminology, retranslate specific segments, and adjust start and end times against a video preview and timeline.
• Segment Voice Regeneration: After you change a line, you regenerate speech for just that segment and re-merge the video. You don't rerun the whole job. Availability depends on the task state, language, and source audio.
• Multilingual Subtitle Versions: You can create separate subtitle versions of the same video for different languages and audiences.
• Flexible Exports: You can download the translated video, original, translated, and bilingual SRT files, plus separated vocal, background, or full audio tracks.
• Agent API: You can upload videos, create translation tasks, poll status, retranslate, and fetch MP4, WAV, and SRT outputs programmatically. Bearer-token auth and idempotency keys guard against duplicate charges.
• AI Agent Skill: An open skill on GitHub connects SoulDub to AI agent runtimes, so you can run translation, subtitles, voice-over, and downloads with natural-language commands.

• Free Plan to Test the Full Workflow: Get 10 credits each calendar month and try the video translation, subtitle editing and dubbing workflow on clips up to one minute long.
• Edit Before You Export: The subtitle editor and segment-level voice regeneration let you fix mistranslations and timing yourself instead of accepting raw machine output.
• Clear Credit Estimates: Each operation shows its estimated credit cost before it runs, and saving edits costs no credits.
• Useful Asset Exports: Download bilingual SRT subtitles and separate vocal, background and full audio tracks for further editing.
• Built for Automation: An API with idempotent task creation and an AI Agent Skill on GitHub make it practical to fit video translation into pipelines.

• MP4-Focused Input: The creation flow normally accepts MP4 files, so you may need to convert footage from other formats before you upload.
• Short Free Tier Limits: The free plan caps tasks at 1 minute, 500 MB uploads, and one active job. That's enough for a test but not for real production.
• 30-Minute Cap on Paid Self-Serve Plans: Standard and Premium both limit tasks to 30 minutes. For longer content, you split the video or go to an Enterprise plan.
• Credits Don't Roll Over: Subscription credits expire at the end of each monthly period, even on annual billing. If your publishing volume is uneven, you may need top-ups, which last 12 months.

• YouTube Channel Localization: Translate tutorials, reviews and other videos into languages such as Spanish or Japanese. Review the generated voice-over and subtitles, then publish localized versions for international viewers.
• Marketing Video Adaptation: Adapt product demos and promotional videos for regional campaigns. Correct brand names and technical terms in the subtitle editor, then regenerate only the affected voice segments.
• Subtitle-Only Delivery: Create translated or bilingual SRT files for educators and course creators who want to retain their original narration while making lessons accessible to international learners.
• Post-Production Handoff: Download available vocal, background and dubbed audio assets for further mixing and editing in professional video software.
• Automated Localization Pipeline: Use the SoulDub API to upload videos, create translation tasks, check processing status and retrieve MP4 and SRT outputs for a content management system or other automated workflow.
• Agent-Driven Workflows: Connect the SoulDub Skill to a supported AI agent runtime and request tasks in natural language, such as translating a video into Korean and generating subtitles.
