Unsupported clip storage location "%s"

Error message

Unsupported clip storage location "%s"

What it means

Raised by ClipchampIE when the Next.js video data's 'storage_location' field is anything other than 'cf_stream'. Clipchamp stores exports on different backends (e.g. Microsoft/OneDrive-backed or pending storage); the extractor only implements retrieval from Cloudflare Stream manifests, so other locations are rejected with the actual value in the message.

Solutions

  1. Open the clip in a browser; if it does not play there either, re-export or publish the project first.
  2. If it plays, note the actual storage_location value in the error — a different backend means this extractor cannot help; use the browser's network tab to find a direct media URL.
  3. Update to yt-dlp, whose Clipchamp support may cover more backends.
  4. For your own projects, re-download/export directly from the Clipchamp UI.
Defensive patterns

Strategy: validation

Validate before calling

import json, re
def storage_is_supported(html):
    m = re.search(r'<script[^>]+id="__NEXT_DATA__"[^>]*>([^<]+)</script>', html)
    if not m:
        return False
    video = json.loads(m.group(1))['props']['pageProps']['video']
    return video.get('storage_location') == 'cf_stream'

Type guard

def is_cf_stream_video(video_data):
    return (
        isinstance(video_data, dict)
        and video_data.get('storage_location') == 'cf_stream'
        and bool(video_data.get('download_url'))
    )

Try / catch

from youtube_dl.utils import ExtractorError
try:
    ydl.extract_info(url)
except ExtractorError as e:
    if 'Unsupported clip storage location' in str(e):
        # different backend; fetch media URL manually from browser network tab
        log('storage backend %s not supported', extract_location(e))
    else:
        raise

Prevention

When it happens

Trigger: Extracting a clipchamp.com video whose export was stored on a non-Cloudflare backend, or a project whose video is not fully processed/published yet (storage_location may be null or a different enum).

Common situations: Older clips created before the Cloudflare Stream backend; drafts/unprocessed exports; Microsoft-era Clipchamp storage changes.
