Some phone’s cameras can already record at QVGA so try finding your camera’s resolution settings and adjust it there.
If your camera doesn’t have this option then we recommend using OpenCamera.
It’s totally free, totally simple and it’s the app we used to make all our videos.
1. Download and install the app from the Play Store
2. Launch the app and click the gear icon (Settings)
3. Scroll down to Video settings… -> Video resolution
4. Select QVGA 320×240
5. Back on the home screen, swivel the camera and hit record
