problem with outputting HD to SD use blackmagic decklink extreme
on Jan 11, 2010 at 8:16:39 am

hi,

we are using blacmagic decklink extreme card, and we have some problem about output from HD (compressor DVCPRO1080i50) to SD (betacam SP):

the video image on the tv screen are interlacing and the line image has flickering.

just for information.
our setting on blackmagic decklink extreme preference.
setting: - set output: SDI & HDMI & Y,R-Y, B-Y
- set input : SDI video & SDI audio

processing: - select output processing: off
- select input processing: off

and our audio/video setting on final cut pro:
sequence preset:blackmagic PAL-10bit
capture preset: blacmagic PAL-10bit
device control preset: blackmagic PAL 25Hz
video playaback: blackmagic PAL-10bit (720x576)

thank you for your help.

Hi Noor,

You should be using the output processing option in the Blackmagic preferences instead of trying to put a 1080i50 into a PAL timeline in Final Cut Pro. This means using a 1080i50 project in Final Cut Pro and let our drivers handle the down conversion to PAL.
