DuoFrame app icon: dual portrait and landscape frames in red and cyan DuoFrame

One take.
Two formats.

DuoFrame records vertical and horizontal videos simultaneously on one iPhone—so you can post to both TikTok and YouTube without filming twice.

  • Record 9:16 portrait + 16:9 landscape at once
  • No second device needed—just one iPhone
  • Built for creators posting cross-platform

Record once, publish everywhere

DuoFrame is an iOS camera app for multi-platform creators. Instead of shooting twice or cropping a landscape master and losing composition, you capture 9:16 and 16:9 in parallel—aligned with how YouTube, TikTok, Instagram Reels, and Shorts actually expect your files.

Three recording modes

Switch modes to match your shoot—same DuoFrame workflow, different output layout.

Multi-Social

Capture two videos at once, saved as two separate files—typically portrait plus landscape for cross-platform posting.

Split

Both cameras side by side in one video—great when you want a single file with dual perspectives in frame.

Overlay

Picture-in-picture—ideal for facecam-style content with a draggable inset over your main shot.

Overlay mode

Picture-in-picture, pro style

Combine a primary angle with a second view in one polished frame—perfect for demos, tutorials, and talking-head setups where context and expression both matter.

Built-in teleprompter

Stay on script while you roll

Open scripts from the camera UI and read naturally while DuoFrame handles recording—so fewer retakes and tighter delivery for YouTube, TikTok, and Reels.

  • ✓ Keep hooks and CTAs consistent across platforms
  • ✓ Pair with Multi-Social or other modes for your workflow

Ship faster to every feed

Less duplicate work, fewer awkward crops, more time editing and publishing. DuoFrame is built for creators who treat YouTube and vertical video as one content system—not two separate productions.
