Simple way to downscale from 1080p@60 to 1080i@60 I have a Canon LEGRIA HF R56 which only outputs 1080p@60 from its HDMI port. Are there any methods to downscale this to 1080p@30 or lower?

Googling this doesn't seem to throw up light. I guess I could use a HDMI capture device to downscale the signal, but then that would defeat the object of downscaling it, as I could just use that device to perform my capture.

I am doing this because my capture device, an Intensity Shuttle, has a maximum input rate of 1080p@30.

EDIT:

From @ProfessorSparkles answer below, the HDMI output could be 1080p@50. I realize that my TV simply says 1080p as the input signal, rather than the framerate.
According to the specs on the Canon site your camera can record in 50i/p and 25p 1920x1080. Are you absolutely sure you can only get 60fps on the HDMI? Because that sounds rather weird that you get more FPS on the HDMI than the camera can actually record.

If you set the recording option to 25FPS normally on canon cameras the FPS should also apply to the HDMI output.
