Recap: MP4 file upload hangs

If Recap hangs when you upload MP4 files for processing, here are the possible causes and solutions.

Possible causes

  • The MP4 file size exceeds Recap's processing limit
  • The video format is not supported by the transcription engine
  • A temporary server-side processing issue
  • Unstable network connection during upload

Solutions

  1. Check file size: Large video files (over 350 MB) may not be processed. Compress the video or split it into shorter segments
  2. Convert the format: Convert the MP4 to audio-only (MP3, WAV) if you only need the transcript. Audio transcription is faster and more reliable
  3. Extract audio: Use an audio extraction tool to keep only the audio track, then upload the audio file to Recap
  4. Try again later: If the issue is temporary, retry the upload later
  5. Check your connection: An unstable connection can interrupt the upload. Use a wired connection if possible

If the issue persists

Contact support with:

  • The MP4 file size
  • The video format and codec
  • The time you attempted the upload
  • How long you waited before giving up
