DuoCam: Dual Format Camera

DuoCam helps you record once and keep more than one useful video version.

Use Dual Format mode to record a single source video and export synced portrait 9:16 and landscape 16:9 MP4 files. Frame the vertical view while recording, check the 16:9 preview, then create one or both formats after recording. Timing, audio and motion stay matched, so the files are easier to edit together.

DuoCam also includes front/rear dual camera recording on supported devices. Record the front and rear cameras at the same time, save separate MP4 source files, and optionally create a picture-in-picture or split-screen video without replacing the originals.

Key features:
- Record once for portrait 9:16 and landscape 16:9 outputs
- Export portrait MP4, landscape MP4, or both
- Adjust the 16:9 crop before export
- Record front and rear cameras together on supported devices
- Save separate front and rear MP4 source files
- Create picture-in-picture or split-screen videos from front/rear recordings
- Choose camera, quality and frame-rate options when supported
- Keep recordings on your device unless you choose to share them

Device notes:
Dual Format export, front/rear dual camera recording, quality options, frame-rate options, audio and export behavior depend on your Android device, camera hardware, available storage and permissions. When a feature is not supported, DuoCam shows the available options instead of forcing unavailable capture.
