When audio transcription fallback runs in SummarizAI

Published 2026-05-21 ·

SummarizAI tries captions first. When none exist, audio transcription may run—slower and less exact than timed text.

Why captions lead

Timed captions anchor sections to moments. Audio-only paths must infer timing, which affects timestamp precision.

Processing time

Fallback can take longer than caption-backed summaries—especially on long uploads. Retry after YouTube finishes auto-captions when available.

Set expectations

Music-heavy or noisy streams may produce weak text. Pick shorter clips or wait for creator captions when possible.
