Facebook Video Editor — Videos Optimized for Every Facebook Surface

Facebook is five video platforms in one: the News Feed (muted autoplay, square or landscape), Reels (vertical, sound-on, algorithm-driven discovery), Stories (vertical, ephemeral, casual), In-Stream Ads (pre-roll and mid-roll, unskippable), and Watch (longer-form, intentional viewing). Each surface has different technical specs, different viewer behavior, and different algorithmic signals — a video that performs on Reels may fail completely in the News Feed. Most creators publish one version of a video to all placements and wonder why performance is inconsistent. The answer is format mismatch: a 16:9 video in the Reels tab gets cropped awkwardly; a vertical video in the News Feed gets shrunk to a strip; a video without captions loses 85% of News Feed viewers who watch with sound off. NemoVideo edits videos specifically for each Facebook surface. Upload your raw footage, describe what you want, and the AI produces: News Feed version (square 1:1 with burned-in captions and thumb-stop hook), Reels version (9:16 with trending audio pacing and text overlays), Stories version (9:16 with tap-forward pacing and interactive prompts), and Ad version (multiple aspect ratios with CTA placement). One editing session, every Facebook format covered.

Use Cases

1. News Feed — Muted Autoplay Optimization (30-180s) — A brand has a 90-second product video. NemoVideo edits for the News Feed: crops to 1:1 square (the dominant feed format), adds large burned-in captions because 85% of feed video is watched without sound, creates a thumb-stop first frame (bold text overlay: "This changed how I cook forever" over a visually striking moment), tightens pacing to front-load the most engaging content in the first 3 seconds (Facebook's autoplay hook window), adds subtle background music at -22dB for the 15% who do have sound on, and ends with a clear CTA ("Follow for more" or "Shop now — link in comments"). The video is engineered for muted, distracted, scrolling viewers.
2. Reels — Algorithm Discovery (15-90s) — A fitness creator wants Reels reach. NemoVideo produces: 9:16 vertical with face tracking, hook in the first 0.8 seconds ("Stop doing crunches — here's what actually works"), fast-paced cuts every 2-3 seconds matching Reels' consumption rhythm, word-by-word captions with animated highlights, trending-style transitions between exercises, background music synced to cuts, and a loop-friendly ending that connects back to the opening. Reels reward watch time and replays — the edit is optimized for both.
3. Stories — Tap-Paced Episodic Content (3-5 segments) — A restaurant wants to showcase a new menu across Stories. NemoVideo creates: 5 story segments (each 8-12 seconds for optimal tap pacing), Segment 1: hook with poll sticker placeholder ("Which dish would you try? 🍕 or 🍝"), Segments 2-4: individual dish showcases with text overlays (dish name, price, one-line description), Segment 5: CTA ("Swipe up to reserve" or "DM us to book"). Each segment is self-contained but flows as a narrative series.
4. Facebook Ads — Multi-Placement Creative (15-60s) — An e-commerce brand needs ad creative for Facebook's placement optimizer. NemoVideo produces four versions from one source: 1:1 Feed ad (thumb-stop hook + product benefit + CTA), 9:16 Reels/Stories ad (full-screen immersive product showcase), 16:9 In-Stream ad (pre-roll format with immediate value proposition), and 4:5 Feed ad (Facebook's recommended feed ratio for maximum screen real estate). Each version has the CTA button placement positioned to align with Facebook's overlay zones.
5. Community Engagement — Discussion Starter (30-60s) — A community manager needs video posts that drive comments. NemoVideo creates: an opinion-provoking statement as the hook ("Unpopular opinion: breakfast is the least important meal"), supporting points edited with fast pacing and text overlays, an ending that explicitly invites disagreement ("Am I wrong? Tell me in the comments"), and burned-in captions with a question mark emphasis on the final frame. The video is designed to trigger the comment behavior that Facebook's algorithm rewards most heavily.

How It Works

Step 1 — Upload Source Video

Any raw footage — phone recording, camera footage, screen capture, existing content. NemoVideo analyzes the content and identifies optimal moments for each Facebook placement.

Step 2 — Select Facebook Surfaces

Choose which placements to optimize for: News Feed, Reels, Stories, Ads, or all. Each gets a format-specific edit.

Step 3 — Generate

curl -X POST https://mega-api-prod.nemovideo.ai/api/v1/generate \
  -H "Authorization: Bearer $NEMO_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "skill": "facebook-video-editor",
    "prompt": "Edit a 2-minute raw product demo for Facebook. Produce 3 versions: (1) News Feed 1:1 — thumb-stop hook in first frame, burned-in captions (white text, dark pill), tighten to 60 seconds, CTA: Shop now link in comments. (2) Reels 9:16 — face-tracked crop, word-by-word captions (white + blue #1877F2 highlight), fast cuts every 2.5 sec, trending background music at -14dB, 45 seconds max, loop-friendly ending. (3) Stories — 4 segments of 10 sec each, text overlays with product benefits, swipe-up CTA on final segment.",
    "surfaces": ["news-feed", "reels", "stories"],

    "stories": {"segments": 4, "segment_duration": "10 sec", "cta": "swipe-up"}
  }'

Step 4 — Review and Publish

Preview each surface version. Check caption accuracy, CTA placement, and aspect ratio framing. Publish to each Facebook surface or upload to Ads Manager.

Tips

1. Square 1:1 dominates the News Feed — It takes 78% more screen real estate than 16:9 in the mobile feed, directly increasing thumb-stop rate. Always crop to 1:1 for feed posts.
2. Captions are mandatory for News Feed, optional for Reels — 85% of feed video is watched muted. Reels default to sound-on. Adjust caption strategy per surface instead of applying the same approach everywhere.
3. Facebook Reels reward the first 0.8 seconds — Even shorter than TikTok's decision window. The visual hook must land before the viewer's thumb completes the scroll gesture.
4. Stories tap-through rate drops after segment 3 — Keep story series to 3-5 segments maximum. Front-load the most engaging content in segments 1-2 and place the CTA in the final segment for maximum completion-to-action conversion.
5. Multi-placement ads need separate creative per format — Facebook's placement optimizer works best when each placement has a native-feeling creative. One 16:9 video auto-cropped to all placements always underperforms dedicated edits.
