# Comment Bait Reel > Build a "Comment X for the links" lead-magnet reel (9:16, ~14s) from the creator's OWN clips + REAL YouTube tutorial thumbnails. Proven format: [b-roll + "POV: you want X" caption] -> [black + "Watch this" + a real YouTube card] xN -> CTA "Comment KEYWORD / it's free". Single-ffmpeg-per- segment then concat. NVENC not needed (fast at this length). Pairs with a ManyChat/GHL keyword funnel that DMs the actual link list. Distilled from the SkynetLabs Claude link-drop reel (2026-06-09, critic-passed). Trigger: "comment bait reel", "/comment-bait-reel", "comment X for links reel", "link-drop reel", "lead magnet reel", "make a reel like this" + a reference showing the POV->Watch this->Comment format, or "watch this YouTube card reel". - Skill: `waseemnasir2k26/comment-bait-reel` (Agent Skill, multi-file: 5 files) - Install (CLI): `npx skillmds@latest add waseemnasir2k26/comment-bait-reel` - Raw SKILL.md: https://api.skillmd.com/api/skills/waseemnasir2k26/comment-bait-reel/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: waseemnasir2k26 (https://skillmd.com/u/waseemnasir2k26) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/waseemnasir2k26/comment-bait-reel --- # comment-bait-reel A lead-magnet reel that converts a scroll into a **comment**, then a comment into a **DM**. The on-screen video is only half the system — the other half is the keyword funnel that delivers the promised links. ## The format (decoded from the viral reference) ``` [B-ROLL + POV caption] → [BLACK + "Watch this" + real YouTube card] ×3 ↓ [CTA: Comment "KEYWORD" / it's free] ``` - Each beat is **short**: b-roll ~1.6–1.8s, card ~2.0s, CTA ~3.3s. Total ~14s. - B-roll = the **creator** (face/desk), graded, with a top dark bar + white "POV: you want X" caption. First b-roll is the **HOOK** — highest-stakes line, most cinematic frame. The hook frame decides reach; spend the most effort here. - Card = pure black, big "Watch this", a **real** YouTube thumbnail framed white, real title + real channel name. NO invented stats (see hard rules). - CTA = black, "Comment \"KEYWORD\"" + a punchy 2-word promise ("It's free") + one subline + a pulsing "comment below" nudge near the bottom. - Cuts are **hard**, each segment opens with a 0.07s white flash (flash-cut) and cards get a slow zoom-in. That reads as "transitions" without fragile xfades. ## Inputs you need before building 1. **Creator clips** — 1–2 clean, caption-free vertical windows of the creator (a tight intense close-up = best hook; a talking-head or desk shot = body). Probe with `cropdetect` (see gotchas) to find caption-free seconds. Letter- boxed clips with burned captions: crop the clean video band and blur-fill. 2. **3 real YouTube tutorials** on the topic — get real `video_id`s (research agent). Thumbnail = `https://i.ytimg.com/vi//maxresdefault.jpg` (fallback `hqdefault.jpg`). VERIFY each id resolves and the thumb downloads (>3KB). Reject dead/private/tiny. 3. **Keyword + lead magnet** — the exact comment word (keep it the topic, e.g. CLAUDE) and what gets DM'd. Wire the DM via ManyChat keyword or GHL. ## Build The engine is `assets/build.template.sh`. Copy it into a working dir next to the source clips, edit the 3 b-roll blocks (clip path + `-ss`/`-t` + POV text), the 3 `make_card` lines (thumb + title + channel), and the CTA keyword. Then: ```bash bash build.sh # writes reel.mp4, regenerates everything idempotently ``` It builds 7 segments → concats with the concat demuxer (stream-copy, instant). Output is **silent by design** — add trending platform audio at upload (boosts reach + you avoid shipping unlicensed music). ## HARD RULES (learned the hard way) - **No fake stats.** Do NOT put invented view counts / "X weeks ago" / durations on the cards. The videos are real but the numbers aren't — fabricating stats about real third-party channels is a no-fake-claims violation AND collapses credibility the moment a viewer clicks through. Card = real title + real channel name only. (This was the #1 critic ship-blocker.) - **Hook is the whole ballgame.** A bright low-effort selfie as frame 1 = scrolled. Lead with the most cinematic/intense creator frame + a high-stakes caption ("POV: you're scared AI will replace you" > "POV: you want to learn X"). - **Keyword = the topic.** The comment word should match what's delivered (CLAUDE for Claude links). One unambiguous word. - **Real thumbnails > designed cards.** Real recs look like genuine tips. Verify each thumbnail visually before building (Read the jpg). - **Creator continuity.** Carry at least the first two b-roll beats with the actual creator, not a stranger/stock — continuity sells the "I'll send you MY list" promise. ## ffmpeg gotchas on Windows (gyan build) - **Font path colon breaks the filtergraph.** `C\:/Windows/Fonts/...` does NOT escape on this build, and fontconfig has no default config. FIX: copy the TTFs to a **relative, colon-free** dir (`fonts/arialbd.ttf`) and reference that. `assets/fonts/` ships arial / arialbd / ariblk. - **Colons inside `text=` break parsing even when single-quoted.** "POV:" / clock values die. FIX: escape the colon as `\:` inside the text value. - **`zoompan` `d` is frames-PER-input-frame.** Feeding a looped image with `-t 2` (=60 input frames) × `d=60` = 3600 frames = a 2-MINUTE clip. FIX: feed ONE frame (`-loop 1 ... -frames:v 60`) and let `d=60` generate the 2s. - **concat demuxer paths are relative to the list file.** If `list.txt` lives in `segments/`, entries must be `s1.mp4`, NOT `segments/s1.mp4`. - **Always pass `-y`** (engine bakes it into `$ENC` + does a clean `rm` first) or ffmpeg blocks on the overwrite prompt in non-interactive shells. - Find the clean video band in a caption-burned letterboxed clip: `ffmpeg -i in.mp4 -vf cropdetect=20:2:0 -f null -` (run at default loglevel — `-v error` HIDES cropdetect output). Note: burned caption text counts as content, so the reported top edge includes the caption; the clean video is the lower sub-band — eyeball a frame to split them, then blur-fill the band. ## Ship checklist 1. Build → extract a frame per beat → **Read them** (visual QA). 2. Independent critic pass (no self-grading): hook strength, card realism, caption legibility, CTA pull, topic coherence, no-fake-claims. Threshold 80. 3. Wire the keyword funnel (ManyChat/GHL) BEFORE posting — the DM must fire. 4. Post silent; add trending audio in-app. Pin a first comment with the keyword. ``` ```
