Frame Extraction
Use When
The user needs selected still frames, a contact sheet, or a review pack from
local video files for persona, product, UI, hook, CTA, before/after, or shot
structure work.
Use video-analysis before or alongside this skill when shot-level
understanding already exists or would materially improve frame selection.
Do Not Use When
The task belongs to ideation, QA, or another released skill listed in the handoff section.
Required inputs are missing and guessing would change the result.
Selection Boundary
Do not default to uniform sampling. Choose the smallest extraction mode that
matches the task intent.
Scope should be explicit: first 3-5 seconds, final 3-5 seconds, full video, or
a requested timestamp range.
Source And Path
Inputs can be one local video, a folder, or a manifest mapping source ids to
local files. If only URLs are available, recover/download local files first.
Preserve source video, timestamp, extraction mode, selection reason, and
source basis in the frame manifest.
Keep internal extraction requests, plan outputs, contact-sheet inputs, and
intermediate manifests under .postplus; keep final frames/contact sheets in
the user-facing output folder.
Review And Handoff
Package outputs for the downstream job: persona frames plus contact sheet and
vibe notes, shot frames plus timestamp list, product-visible frames plus proof
notes, or UI frames plus readable text notes.
For long videos, start with the bounded first pass, then expand only after the
first manifest proves the mode is useful.
Return final frame folders, contact sheets, and frame manifest paths.
Stop Conditions
Stop when required user intent, source evidence, or owned input artifacts are
missing and guessing would change the result.
If an owned CLI or script command fails, report the exact error and stop. Do
not bypass the failure with metadata-only answers, readiness probing, local
payload rewrites, fallback providers, or unpublished tools.
Public Command Boundary
Choose the smallest matching command or workflow from the user input and run
it directly.
If an owned CLI or script command fails, report the exact error and stop. Do
not bypass the failure with metadata-only answers, readiness probing, local
payload rewrites, fallback providers, or unpublished tools.
