Call to action

The ending decides what a view turns into. It sits over the last 2-3 seconds. It never adds extra seconds.

Pick the ending by where the video goes

One ending per file. When you render several sizes with every-format, give each one its own ending.

A. Comment keyword

Step 1: Ask for three things, then wait

1. The keyword, 4 or 5 letters, one word. Short words get typed. Long ones get skipped.
2. What it sends, in plain words ("the 16 skills", "the free guide").
3. The delivery tool (ManyChat or similar) and whether the flow is live yet.

The look

• A clean copy of the native Instagram comment box, centred. Your avatar circle, "Add a comment…", the keyword typing in at about 8 characters a second.
• Then the reply: a DM bubble ("Here you go") and a link card under it, with clear space between the two.
• It slides up into the last frame, over the payoff. The payoff stays visible behind it.
• Holds to the very last frame.
• Spoken line to match: "Comment [KEYWORD] and I'll send you [the thing]."

Step 2: Build brief (paste into Claude Code)

Over the last [2.5]s of video.js, add the comment CTA on top of the last beat. Do not cut away from the last beat.
A white comment sheet rises from the bottom to y 1060 (36px top corners, soft shadow): a 64px avatar circle, the field "Add a comment…" in grey 40px, then "[KEYWORD]" types in at 8 characters a second in #1d1d1f.
0.6s after the last letter, the field clears and a DM bubble "Here you go" (white, 28px corners) appears at y 760, then 0.3s later a link card "[WHAT IT SENDS]" with a 120px thumbnail under it, 40px gap between them.
Everything holds to the last frame. Nothing below y 1500 is text.

Step 3: Before you post

• The keyword flow is live and tested. Comment the keyword yourself from another account and check the DM arrives.
• The thing it sends exists and matches what the video promised, word for word.
• The caption repeats the keyword in its first lines.

What I learned the hard way

• A custom-styled box looks cheap. A faithful copy of the native comment UI looks premium.
• Never add seconds for the CTA. Put it over the ending.
• An unsaved automation is a lost automation. Duplicate a live flow, edit it, set it live, and read it back.

C. One-button end card

Ask for two things, then wait

1. The action, three words or fewer ("Book a call", "Start free", "Reply 'yes'").
2. Where it goes, the real URL or the reply address. Never a placeholder in a finished file.

Build brief (paste into Claude Code)

Over the last [2.5]s of video.js, add an end card on top of the last beat. Do not cut away from the last beat.
A white card rises from the bottom (40px corners, soft long shadow), centred in the motion panel, PANEL.w * 0.7 wide.
Line 1, 56px, brand ink: the promise in five words or fewer ("Get this set up for you").
Line 2: one pill button in the brand accent with white text: "[ACTION]", and the URL under it in grey 32px.
The button settles with a small spring 0.3s after the card. It holds to the very last frame.
Spoken line to match: "[ACTION] at [short URL]."

Check

• The URL is real and loads. Open it once.
• The button text matches the spoken line word for word.
• On a sales email, the thumbnail (frame 0) shows the person's name or company if the email is personal.
