 The Insta360 ONE RS provides the **horizon lock** feature, but only in **software post-processing**.

-FIXME How are the videos created in this way?
+Like any other videos captured with **Post FlowState stabilization**, you will find unstabilized videos on the SD card. The footage will have un-cropped frames and embedded metadata about **angular velocity**, **accelerometer** and **exposure time**. For each clip, both the low resolution video and the full resolution video have the same metadata.
+It is possible to extract such metadata e.g. with the **exiftool** command line tool:
+<code bash>
+exiftool -api RequestAll=3 -api largefilesupport=1 -extractEmbedded "video.mp4"
+</code>
+It seems that there are about 1000 samples per second for angular velocity and accelerometer and one exposure time for each frame.
