Failed video imports usually stem from permission restrictions, network timeouts, incompatible container codecs, or rate limits on the hosting platform. When ClipMaster cannot ingest your source file, follow this structured troubleshooting workflow to resolve the issue before re-spending credits.
Credit Protection
ClipMaster only deducts credits for successful video transcriptions. If an import fails during the initial connection or download phase, no credits are charged.
Diagnostic Checklist
Follow these systematic steps to isolate and resolve import issues:
Verify Link Accessibility
If importing from a URL (e.g., YouTube or Vimeo), ensure the video is fully public. ClipMaster cannot ingest age-gated, private, members-only, region-locked, or copyright-disputed videos.
Inspect the File Container & Codecs
For direct file uploads, confirm that the file format is standard MP4 or MOV, encoded with H.264 or HEVC video codecs and AAC audio. Avoid importing raw camera formats (like ProRes or RED raw) without compressing them first.
Test with a Simplified URL
Use the canonical video URL. Strip out any extra query parameters (e.g., playlist IDs, referrer tracking, or timestamps) and try the raw link again.
Check for Host Rate Limits
If you are running a high-volume batch import and suddenly experience failures, the hosting platform may have rate-limited our ingestion servers. Pause your queue and wait 15–30 minutes before resuming the imports.
Error Scenarios and Solutions
| Observed Behavior | Probable Cause | Recommended Action | | :--- | :--- | :--- | | Stuck at 0% Ingestion | Hosting platform is blocking automated downloads. | Download the video locally first and upload the raw file directly. | | Transcription Failure | Audio track is corrupted or uses an unsupported multi-channel layout. | Re-export the video with standard stereo (2-channel) AAC audio. | | Invalid Format Alert | The file container is corrupted or truncated. | Verify that the file plays correctly in a local media player (like VLC). |
