Camera settings

Settings are stored on the camera, so they stay with it whichever phone or computer you use. On Trinet Mono they apply to card recordings as well as USB streaming. Settings a camera's firmware doesn't support yet are shown with Update the camera firmware to enable them.

Picture

Brightness, contrast, saturation, sharpness, gain, white balance (automatic or a colour temperature), manual exposure, and the status light.

Sound

On cameras with microphones: mute, automatic gain, gain level and sample rate (16, 44.1 or 48 kHz). The camera also has a hardware mute switch.

Video

Setting What it does
Bitrate 1–20 Mbps (0.5 Mbps steps), with constant (CBR) or variable (AVBR) rate control. The camera restarts to apply it. Stereo card recordings always use 10 Mbps per eye.
Recording codec H.264 or H.265 for recordings the camera writes to its own card. Applies from the next take, no restart. The live USB stream is always H.264. Needs camera firmware 0.5.7 or newer on stereo cameras (0.5.9 on Mono).
Exposure range Minimum and maximum exposure time.
Split recordings Off, 5, 10, 15, 30 or 60 minutes — also called chunking. Cameras ordered that way are set at the factory, with lengths up to 240 minutes. A long recording is saved as a series of takes of that length instead of one very large file, so a problem costs you one take rather than everything. Applies from the next recording, no restart. Expect a pause of 10–20 seconds between takes. How to set it.
Location Mains frequency, 50 or 60 Hz, to avoid flicker under artificial light. Choose your country's mains frequency.

H.264 or H.265?

H.264 plays everywhere and decodes fastest — the best default for data pipelines. H.265 gives smaller files at the same quality if your tools support it.

Set split recordings (chunking)

You need Trinet app 0.5.5 or newer. On Trinet Stereo and Stereo GS, use camera firmware 0.5.13 or newer, which starts and ends each take cleanly.

  1. Connect the camera to the phone in USB webcam mode: no memory card, light white. The home screen shows Camera ready. Then tap Camera settings.

    The camera shows as Connected.
  2. Scroll down to Video → Split recordings. The card shows the camera's current setting, for example Current: off — one continuous file. A camera set to split at the factory shows its length here. Tap Read from camera to refresh it.

  3. Tap a length: 5, 10, 15, 30 or 60 min, or Off for one continuous file. The button fills in, and the app confirms Recordings will be split every … min — applies to the next recording.

  4. Record as usual. The setting is saved on the camera and applies from the next recording to its memory card. There's no restart, and a recording already running isn't changed. Unplug the camera, insert the card and start recording with the button.

On Stereo and Stereo GS with firmware 0.5.13, each part is saved as its own numbered take (take0001, take0002, …) directly in Trinet/recording/. That replaces the folder of parts the app's description mentions. See Split recordings for what a split session looks like on the card.

If the card says Not available on this camera's firmware, update the camera firmware first.

Wireless

Broadcast recording status — lets phones follow the camera's recording status over Bluetooth while it records to its card (see Wireless status). On by default with firmware 0.5.9 or newer; the camera applies a change from its next start.

Advanced

Setting What it does
Keyframe interval (GOP) 1–600 frames; default 30 (one keyframe per second). The camera restarts to apply it.
Embed IMU samples Carry motion data inside the video stream (on by default; needed by the app and SDK).
Calibration Read the calibration stored on the camera, Upload from file (a calibration.json), or Lock calibration so it can't be overwritten.
Boot mode The mode the camera starts in when no card is inserted: USB webcam, iPhone or card recording. The camera restarts. See Recording modes.
Restore defaults Returns picture, sound and video settings to the factory defaults. Keeps the boot mode, calibration and kit pairing.
