video-translate_skill

Overview

This skill translates and dubs existing videos into multiple target languages using HeyGen. It supports lip-synced dubbing, audio-only translation, multi-language batches, custom vocabulary and subtitle handling. Provide either a public video URL or a HeyGen video ID to start a translation job.

How this skill works

You create a translation job by calling HeyGen's /v2/video_translate endpoint with a video_url or video_id and the desired output_language(s). The API returns a translate_id which you poll until the job status is completed. When finished, the response includes a downloadable URL for the translated video or audio. Advanced options let you supply custom SRTs, vocabulary, speaker count, and toggles like audio-only, music removal, or speech enhancement.

When to use it

• Translate an existing marketing, training, or product video into another language
• Create lip-synced dubbed versions for international audiences
• Produce faster audio-only translations when lip-sync is not needed
• Generate multiple language variants in parallel for global distribution
• Preserve brand terms or supply custom subtitles during translation

Best practices

• Use high-quality source videos with clear speech for best results
• Test with short clips before processing long videos to validate settings
• Set speaker_num for multi-speaker content to improve speaker separation
• Use translate_audio_only for faster turnaround when lip-sync isn't required
• Provide a vocabulary list for product names or jargon to preserve exact terms
• Allow up to 30 minutes per translation and use webhooks or polling to track progress

Example use cases

• Localize a product demo into Spanish, French and Japanese using multi-language output
• Convert interview footage to a dubbed version with lip-sync and voice cloning
• Produce audio-only translated podcasts or voiceovers for distribution
• Translate training videos and attach custom SRT subtitles for compliance
