WHAT IT DOES

What video_to_music does on Elevenlabs

AI agents use video_to_music to create or update resources in Elevenlabs, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Elevenlabs environment.

Parameter	Type	Required	Description
`tags`	array	—	Optional list of style tags (e.g. ['upbeat', 'cinematic']). A maximum of 10 tags is allowed.
`model_id`	string	—
`description`	string \| null	—	Optional text description of the music you want. A maximum of 1000 characters is allowed.
`output_path`	string	—	Where to write the returned bytes. Relative paths resolve against ELEVENLABS_OUTPUT_DIR. Omit it to get the data inline as base64 (small files only).
`videos_paths`	array	—	One or more video files sent via FormData array (multipart/form-data). They will be combined into one codec in order. A maximum of 10 videos is allowed, where t
`output_format`	string	—	Output format of the generated audio. Formatted as codec_sample_rate_bitrate. So an mp3 with 22.05kHz sample rate at 32kbs is represented as mp3_22050_32. MP3 w
`sign_with_c2pa`	boolean	—	Whether to sign the generated song with C2PA. Applicable only for mp3 files.
`videos_filenames`	array	—	Filenames to send for "videos". Some endpoints infer the audio format from them.
`videos_base64_list`	array	—	Base64 contents for "videos", one entry per file. Use this when the server cannot read your local disk.

Parameters from the server's own tool schema.

video_to_music Rate-limited

video_to_music stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
