SD Card

The microSD card must be installed in the slot which can be accessed by removing the back cover. The recommended microSD card speed rating should be 10MB/s or faster (Speed Class 10, UHS Speed Class U1, Video Speed Class V10 or better). Refer to the chart below for SD card selection.

SD card speed class chart (sdcard.org)

There is no detent or any other support for correctly inserted card, you just need to push the card until it stops, look at the example below.

The microSD card cover is somehow loose and can come off right in the middle of the flight. It is recommended to fix it with piece of tape.

All camera settings can be accessed and changed by altering the configuration file [thumb.conf] located on the SD card.

GyroFlow stabilization

RunCam Thumb has built in gyro and can record gyro data alongside the video recordings. The gyro data is stored in the separate files with *.gcsv extension. You can stabilize the video footage with GyroFlow software.

Download Gyroflow from here: https://github.com/gyroflow/gyroflow/releases

Open (or gust drag and drop) video file and gyro motion data file into the GyroFlow software.

Select the RunCam Thumb lens profile for barrel distortion correction.

Press “Auto sync

Hit the “Export” button and GyroFlow will render the stabilized video file.

Below is an example of raw video file recorded by RunCam Thumb and stabilized with GyroFlow.
