Video Transcription

Video Transcription

Use When

• The input is a video file and the goal is speech extraction, timed transcript, caption generation, multilingual transcript, or edit-prep timestamps.
• Use media-analysis instead when the user needs semantic visual analysis.

If a timed transcript already exists and only subtitle output is requested, skip transcription and read the local subtitle conversion reference.

Do Not Use When

• The task needs new creative generation or visual analysis rather than speech or subtitles.
• Required inputs are missing and guessing would change the result.

Execution Boundary

• Hosted video transcription runs through the public postplus media transcribe verb and is async. The generated example below shows the endpoint key.
• Pass a local path, HTTPS URL, existing PostPlus media reference, or data URI directly to --video. The CLI validates and prepares local media before the single hosted submit.
• Request timestamps by default when results drive subtitles or edit decisions.
• Hosted video transcription is async. Submit records the run handle, current status, and transcript artifacts when available. Inspect the returned format; do not assume a fixed normalized transcript schema.

Source And Path

• Before submit, derive durationSeconds from the source video or URL and pass it through the endpoint's duration flag for request validation.
• Start with one source file before larger batches.
• Keep internal requests, responses, normalized transcripts, and downloaded artifacts under .postplus/video-transcription; keep final user-facing transcript exports outside .postplus.

Handoff

• If status is pending, preserve the result path and follow the CLI-returned action or resume command for the same operation. Do not submit another job. Stop and report when the CLI wait/recovery boundary is reached.
• When SRT/ASS is requested, use the actual timed transcript and read local subtitle conversion [blocked]. Convert locally without another hosted request; do not invent a CLI export command.

Stop Conditions

• Stop when required user intent, source evidence, or owned input artifacts are missing and guessing would change the result.

Public Command Boundary

• Choose the smallest matching command or workflow from the user input and run it directly.

• Readiness diagnostics: postplus doctor --skill video-transcription.

• Use postplus media schema --json only when you need the full endpoint, flag, and enum contract or are repairing an unknown request shape.

• Run the hosted transcription job with the generated command below; do not use another execution interface.

• Pass the source directly through --video; do not pre-upload it or construct a manual request object.

• If the CLI returns a quote-confirmation challenge, obtain user approval for its scope and cost before running postplus quote confirm --json --challenge-file <challenge.json> and retry with the returned token.

postplus media transcribe transcription-video \  --video ./reference.mp4 \  --duration-seconds 1 \  --wait \  --output ./result.json

Follow the CLI's structured result and reported next action; do not infer recovery from free-text messages. Wait for explicit user approval when requested; an action does not authorize spending, publishing, or overwriting. Resume the same operation through its returned checkpoint or action; never resubmit uncertain work, repeat exhausted recovery, or switch providers to bypass failure.
