Transcription Quality​

Factors affecting quality:

  • Audio clarity
  • Speaker accents
  • Background noise
  • Language

File Limits​

Video uploads use both plan and file-type caps.

Effective per-file limit = min(plan limit, video hard limit)

  • Video hard limit: 1 GB
PlanMax Video Size
Free25 MB
Starter200 MB
Pro500 MB
Pro+1 GB
Business1 GB
Enterprise1 GB
note

Long videos may still hit processing timeouts even when file size is within limit.

See Subscription Plans for all file types.

note

Editing a transcript triggers re-embedding, which may affect existing queries.

Video Sources in Responses​

When a chatbot answers using video content, the source card displays a video icon next to the video name so users can distinguish it from PDF sources.

If your knowledge base mixes PDFs and videos, PDF sources may dominate the displayed results since text embeddings typically score higher. Enable Balanced Sources in AI Settings to ensure video sources appear alongside PDFs when relevant.

Best Practices​

  • Use videos with clear audio
  • Prefer videos with single speakers
  • Consider adding timestamps for navigation
  • Edit transcripts to fix obvious errors

Troubleshooting​

Transcription Failed​

Common causes:

  • No speech in video
  • Unsupported audio format
  • Video file too large for current upload limits
  • Video processing timed out

Solution: Check file format and upload limits, then retry.

Poor Transcription Quality​

  • Verify audio quality in the original video
  • Consider uploading a higher quality version
  • Manually edit the transcript
