ElevenLabs supports videos up to 600 seconds

Error message

ElevenLabs supports videos up to 600 seconds

What it means

Duration cap in generate_bgm: the video is longer than MAX_VIDEO_DURATION_SECONDS (600s), the documented ElevenLabs video-to-music limit. Rejected client-side so a multi-hundred-MB upload is not attempted just to receive a 422/413.

Solutions

1. Check the duration unit first: a value like 10800 almost always means minutes/milliseconds were passed as seconds
2. Split the video into <=600s segments and generate/concat audio per segment if long content is required
3. Trim the video to <=600 seconds if full-length music is not a hard requirement

Example fix

# before
generate_bgm(video, out, total_seconds, prompt)  # total_seconds = 1500

# after
MAX_LEN = 600
segments = split_video(video, MAX_LEN)  # each <= 600s
total_seconds = min(total_seconds, MAX_LEN * len(segments))
audio = generate_bgm(segments[0], out, total_seconds, prompt)  # per-segment strategy

from app.services.elevenlabs_music import MAX_VIDEO_DURATION_SECONDS

assert 0 < duration <= MAX_VIDEO_DURATION_SECONDS

When it happens

Trigger: Any generate_bgm call where the validated duration exceeds 600 seconds — e.g. long-form compilations, a duration computed in the wrong unit (minutes passed as seconds), or a concat bug joining the same clips repeatedly.

Common situations: Unit mistakes (duration in milliseconds or minutes fed to a seconds parameter), 'loop video N times' features multiplying length past 10 minutes, or legitimately long content that simply exceeds the API plan.
