NOTE: Ki Pro Rack, when used with select Sony cameras, only works with HDMI timecode matched to
the recording format and HDMI output: 1080i 29.97 (1080i 59.94) or 1080i 25 (1080i 50). If a
1080p 24 recording on the Sony camera's internal media with a 1080i 29.97 HDMI output is
produced, the Ki Pro Rack may not respond to HDMI timecode as expected.
