HD-SDI is used as a bit of a generic term...

There are a number of different formats that may fall in to this category, correctly and possible incorrectly...

Do check your card installation as suggested above.

Essentially you need to check what the exact resolution and refresh rate is to determine whether the PE1 card will accept it.

The PE1 & PE4 card will accept the following:


Standard --- Name --- Video Formats
SMPTE 259M - SD-SDI - 480i, 576i
SMPTE 344M - ED-SDI - 480p, 576p
SMPTE 292M - HD-SDI - 720p, 1080i

All at either 50Hz or 60Hz
Also 1080p but only at 25Hz and 30Hz

If someone says "HD-SDI" - it could either mean: 1080i / 1080p / 720p at either 50 or 60 Hz
