Just out of curiosity; why does my nano indicate 720p50 when setting my EX3 in that mode and 1080sf25 when setting the ex3 at 1080p25? In other words: why is the indication p in the first case and sf in the second?

Dear Cees,

We ran out of room.

1080sf25 means 1080psf25 is being recorded at 1080p25, in other words we are coverting PSF to Progressive before we record it. In other words: Videp|Record PSF>Prog(ressive) is set on.

720 never uses PSF sowe just put out 720pxx.
