In consumer markets Blu Ray recording format is limited to 1080p/24, 1080i/60 
or 720p. The 1080p/60 is not format that stored on Blu Ray. As far as Master 
Format I am sure it is the best. But practically is it use for that purpose in 
production and postprodcution. After all it is far more expensive to create 
1080p/60 then 1080i/60 or 1080p/24. For theatrical release I was under 
impresionthat 1080p/24 is ideal because it is displayed at 1080p/72 in the 
digital theaters. The 1080p/60is actually hindernce for that purpose.

Yes, there are lots of 1080p/60 (and 1080p/50) customers. All the digital cable 
we make is now tested to 4.5 GHz (the third harmonic of the occupied bandwidth 
of 1080p/60). Evertz told me that they're selling as much 1080p/60 equipment as 
regular HD (1080i/720p). I think there are three basic reasons:
1. 1080p/60 makes a great Master Format to convert to 1080i or 720p with NO 
artifacts.
2. There are 1080p BluRay players and displays/projectors. When 1080p becomes a 
viable broadcast format, you will be given a Gold Star for shooting in 
1080p/60, since your content can be sold again (and again)
3. 1080p/60 is borderline theatrical, some would say ACTUAL theatrical release, 
so you can multipurpose your gear for TV or Movies - or anything inbetween.
As far as the cable goes, just remember that 1080p/60 distance are less than 
1080i or 720p. I would be glad to send the latest distance charts.

Does 1080p/60 format is actually used for production or postproduction?
