Ever made a cool video that just doesn’t fit the frame? Or spent hours adding captions manually? Many short-form creators feel your pain. Luckily, compact AI video editors are here to save the day. These tools are super smart and super fast—exactly what you need to keep up with viral trends.
TL;DR: If you’re a creator making 9:16 Reels, TikToks, or Shorts, you need tools that do the heavy lifting—resizing, formatting, captioning. We’ve rounded up the top 5 compact AI video editors Reddit users swear by. They’re easy to use, lightning-fast, and packed with useful features. Let the auto-magic begin!
Why Compact AI Video Editors?
Time is everything when it comes to short-form content. A minute’s delay could cost you trending reach. Compact AI editors are lightweight, fast, and run on autopilot. They handle the boring stuff like resizing, reframing, and captioning. That way, you can focus on being creative.
What Makes an Editor “Compact”?
- No huge downloads or apps—many run in your browser.
- Simple UI you don’t need a PhD to understand.
- Quick processing and export times.
- Perfect for mobile creators or those with low-spec devices.
Okay, let’s jump into the ones creators on Reddit keep recommending!
1. Opus Clip – The Smart Reframer
What’s cool? Opus Clip takes your horizontal (landscape) videos and turns them into multiple vertical (9:16) clips, automatically. It’s perfect for turning podcasts, webinars, or long YouTube vids into snackable short content.
- Auto-detects interesting moments based on AI
- Adds dynamic zooms and transitions
- Generates viral-style clips with captions
Why Reddit loves it: It actually picks the best segments. No more scrubbing through 30 minutes of footage.
Downside: Editing tools are limited—you might still want to tweak in a second app if you’re picky.
2. Descript – The Edit-by-Text Genius
What’s cool? You edit video the same way you’d edit a Word document. It transcribes your audio and then lets you cut or move scenes just by deleting or rearranging text.
- Automatic transcription and subtitle generation
- Studio Sound cleans up your audio
- “Remove filler words” button = chef’s kiss
Why Reddit loves it: You can make polished Reels with zero editing experience. Plus, it’s fun to use!
Downside: You’ll need a decent machine for full performance. Lightweight, but not featherweight.
3. CapCut – The TikTok Darling

- Mobile and desktop versions
- Crazy simple auto-caption tool
- Templates for Reels, Shorts, and TikToks
Why Reddit loves it: It’s free, packed with features, and beginner-friendly. Many creators say it’s their go-to for quick posts.

4. Veed.io – The Caption King
What’s cool? If crisp, perfectly timed captions are your jam, Veed.io nails it. You can burn them in, style them your way, or download them separately.
- Lightning-fast auto-captions with multiple language support
- Great preset crop sizes for all platforms
- One-click translations for international reach
Why Reddit loves it: The interface is clean, and it’s super reliable for quick content batches. Many creators swear by it for caption-heavy content.
Downside: Free version limits exports to 720p. Higher resolutions need a paid plan.
5. Runway – The Artsy AI Lab
What’s cool? Runway is more than a video editor. It uses generative AI to remove backgrounds, track motion, and even create scenes. Think of it as the creative toolbox for next-generation creators.
- 9:16 formatting and captioning baked in
- Magic eraser removes unwanted stuff in seconds
- Real-time collaboration features
Why Reddit loves it: You can create cinematic short-form content without touching After Effects. It’s like having a tiny post-production studio in your browser.
