How a long video gets handled
A three-hour interview does not fit in one model's attention span, and summarizing it by reading the first ten minutes is worse than useless. The transcript is split and read in parallel instead.
up to 7 balanced parts · read in parallel
Fetch
The transcript is pulled from the video's caption track. If the transcript had to be cut short at the cap, the summary is marked as truncated — and the sections say so instead of quietly guessing at the missing tail.
Map, in parallel
The transcript is cut into balanced parts at line boundaries, and each part is read on its own. Every part continues if a sibling fails — one flaky provider call costs you one part, not the whole run.
Compose
The parts are merged back in transcript order into one brief. Every timestamp and number survives the merge exactly as it appeared — a timestamp is never estimated from context.
The five sections
Fixed order, every run. You learn where to look once, and a truncated or partial video still reads the same shape as a complete one.
TL;DR
The whole video in a few sentences. If you read nothing else, read this.
Key points
The substantive claims and arguments, in the order the video makes them.
Timestamps
A chronological mm:ss — what happens list. You can jump straight to the part you care about instead of scrubbing.
Quotes
Verbatim lines with their timestamps — so you can check the wording yourself instead of trusting a paraphrase of something that mattered.
Action items
Only what the video actually recommends. Nothing is invented to fill the section — if the video recommends nothing, the section says that.
Your language, not the video's
Summarize a Spanish lecture and get the brief in Bahasa Indonesia — or keep it in English if that is what you read. The summary follows your locale, not the transcript's.
One deliberate exception: verbatim quotes stay in their original language. A quote is only worth including if it is exactly what was said, so translating one would defeat the point of having it.
Translated summaries are cached, so re-reading the same brief in another language costs nothing after the first time.
Summarize the video you keep skipping
Three hours of podcast, one structured brief with the parts you actually need.
