Which devices support dual camera recording?

Simultaneous front and rear capture requires an iPhone XS or newer, or a recent flagship Android device. Cametas detects support on launch and hides dual modes on hardware that cannot do it.

Is the map layer burned into the video file?

Yes. The map, route line, coordinates and date-time title are composited into the frames as you record, so the exported MP4 carries them everywhere.

Does the teleprompter work while recording both cameras?

It does. The prompter floats above the live preview and is deliberately excluded from the composited output.

Do you upload my recordings anywhere?

No. All capture, compositing and export happens on device. Recordings stay in your library until you choose to share them.

Cametas for Android — 14MB Kotlin Native Dual Camera, Map Overlay & Teleprompter

Deep-Dive: Android Camera2 Architecture & Recording Modes

Cametas for Android utilizes direct OpenGL ES 3.2 shaders and Android MediaCodec NDK hardware pipelines. On flagship devices (Samsung Galaxy S21–S24, Google Pixel 6–9, Xiaomi, OnePlus), Cametas captures both physical camera sensors simultaneously without dropped frames or thermal throttling.

Dual Camera Mode (30/60 fps)

Record front selfie and rear main cameras concurrently. Switch between Picture-in-Picture circular bubbles, movable corner overlays, or 50/50 split screen shots.

Android Screen Recording + Facecam

Stream apps or games live while keeping your selfie camera visible in a crisp circular presenter bubble.

Smart Auto-Teleprompter

Floating script prompter over camera preview. Adjust scroll speed (WPM), text size, and opacity. Stays hidden from final output MP4.

Vector Map & Route Layer

Embedded vector map tile overlay with live GPS route tracking. Burned permanently into exported video frames.
