ElevenLabs video proxy is empty or exceeds the 200 MB limit

Error message

ElevenLabs video proxy is empty or exceeds the 200 MB limit

What it means

ElevenLabsMusicError raised after a successful FFmpeg run when the produced proxy is missing/0 bytes or exceeds MAX_PROXY_BYTES (200 MB, app/services/elevenlabs_music.py:23). The upload endpoint rejects oversized videos, so the code pre-checks locally and removes the offending proxy. An empty proxy despite returncode 0 usually means the encode produced no output stream (video-only filter chain on an audio-less file, or output path unwritable in a subtle way).

Solutions

  1. Reduce proxy size: lower resolution/bitrate or trim duration so the encoded proxy lands under 200 MB.
  2. For the empty case, run the same FFmpeg command manually and read its stderr — usually a filter or codec issue producing zero frames.
  3. Check disk space in the output directory; a full disk can truncate the proxy.
Defensive patterns

Strategy: validation

Validate before calling

import os
MAX_PROXY = 200 * 1024 * 1024

def proxy_will_fit(duration_s: int, bitrate_bps: int = 2_500_000) -> bool:
    return duration_s * bitrate_bps / 8 < MAX_PROXY

Try / catch

try:
    generate_bgm(video_path, output_path, prompt)
except ElevenLabsMusicError as e:
    if 'empty or exceeds the 200 MB limit' in str(e):
        trim_or_lower_bitrate(video_path)
        generate_bgm(video_path, output_path, prompt)

Prevention

When it happens

Trigger: A source so long/large that even the downscaled proxy stays over 200 MB (e.g. 600s at high bitrate); or FFmpeg writing a 0-byte file because the encode silently produced no frames.

Common situations: Long 10-minute videos at the duration limit with high bitrate targets; users bypassing the proxy scale-down by config; disk-full conditions leaving a truncated file.
