Solution
When slow motion recording is activated, the camcorder records using a progressive frame rate (shooting frame rate) that is different from the playback frame rate. Recording a clip at a higher frame rate than the [Frame Rate] setting will result in a slow motion effect during playback (up to 1/5 of the original speed).
Sound is not recorded when slow motion recording is activated. Also, the maximum recording time of a single clip is the equivalent of approximately 6 hours of playback time.
Slow motion recording is available only for XF-HEVC clips.
