About this tool
Mark hook, beat and review timestamps along a short video's timeline.
This marker is a plain-text timeline sheet for a short vertical video: you write one line per moment in the form timestamp | label | note — 00:02.500 | Beat | Visual change — next to a 9:16 preview frame that draws the top safe-zone boundary and the bottom band where captions and player controls sit. You can drop in a reference frame or clip to look at while you write, then export the whole sheet as a dated text report. It is for creators and editors planning where the hook lands and what has to stay clear of the interface, before they open an editor.
Open Short-Video Hook Marker on AltFTool — it loads instantly in your browser.
Attach a frame or clip with 'Optional reference image/video' to see it inside the 9:16 preview.
Write one line per moment in Content and review notes as timestamp | label | note — 00:02.500 | Beat | Visual change — checking each against the Top safe-zone boundary and the Caption / controls obstruction review band.
Press Export review report to download altftool-short-video-hook-marker.txt containing your sheet and an ISO 8601 generation timestamp.
A 9:16 preview with a marked top boundary and a bottom caption and controls band sits beside your notes as you write them.
The sheet uses mm:ss.mmm, so 00:02.500 means a specific frame instead of 'around two seconds in'.
The report carries an ISO 8601 generation timestamp with your notes, so two versions of the same clip never get confused.
Minutes, seconds and milliseconds: 00:02.500. Each line takes three parts separated by the pipe character — timestamp, label, note — and the starter sheet uses the labels Hook, Beat and Review, which you can rename to whatever your team uses.
No. Nothing is scanned or auto-detected — this is a structured notepad plus a safe-zone preview, and every timestamp is one you decide and type. The optional image or video you attach is shown as a reference only.
A plain .txt file containing the tool name, an ISO 8601 timestamp of when it was generated, your full sheet, and a closing reminder to check the timings and safe-zone assumptions against a real platform preview. It downloads as altftool-short-video-hook-marker.txt.
No — the frame is a generic 9:16 guide, not a per-platform overlay, and each app places its caption, handle and button furniture differently and changes it over time. Use it to plan, then confirm in each platform's own upload preview before publishing.
