Nodes

Pinch Voice Translation (Dubbing)

The main node. Provide either a public URL or a local file path to an audio/video file. The node uploads (if local), creates a dubbing job, polls until completion, and downloads the result to your ComfyUI output directory.

Inputs:

| Name | Type | Required | Default | Description | |------|------|----------|---------|-------------| | target_language | Dropdown | Yes | es | Language to dub into | | source_language | Dropdown | Yes | auto | Source language (auto-detect by default) | | api_key | STRING | Yes | | Your Pinch API key | | media_url | STRING | No | | Public HTTP(S) URL to an audio or video file | | local_file_path | STRING | No | | Absolute path to a local audio or video file (max 500 MB) | | reduce_accent | BOOLEAN | No | False | Reduce accent in dubbed audio | | translation_lag_time | FLOAT | No | 0.0 | Delay before dubbed speech starts, in seconds (0–5) | | original_speech_volume | FLOAT | No | 0.0 | Volume of original speech mixed under the dub (0–1) | | poll_interval | INT | No | 10 | Seconds between status checks (5–60) |

Provide either media_url or local_file_path — not both.

Outputs:

| Name | Type | Description | |------|------|-------------| | job_id | STRING | Pinch dubbing job ID | | output_path | STRING | Local path to the downloaded dubbed file | | status | STRING | Final status message | | subtitles_original | STRING | Original language subtitles (SRT format) | | subtitles_translated | STRING | Translated language subtitles (SRT format) |

Subtitles are returned as SRT strings and also saved as .srt files alongside the dubbed media in your output directory (e.g. pinch_dubbed_<job_id>_original.srt and pinch_dubbed_<job_id>_translated.srt). Empty strings are returned if the API does not provide subtitles.

Jobs time out after 30 minutes. If a job times out, the job_id is still returned so you can check its status manually with the Status node.

| Name | Type | Description | |------|------|-------------| | status | STRING | Current job status | | output_url | STRING | Download URL (if completed) | | subtitles_original_url | STRING | URL to original language subtitles (SRT) | | subtitles_translated_url | STRING | URL to translated language subtitles (SRT) |
