I'm a video assist operator and work mostly in commercial films and occasionnaly on special effects movies. I've started using modul8 for on set previz of sfx for motion control shots and others. I'm mostly using chroma key and mix/wipes(done with crop filter)
Have any of you encoutered problems using the chroma key filter (with a film camera the video signal is usually very noisy out of the video tap and it is hard to key) and is there a workaround solution to this other than applying more than one luma key green (or blue) to key the variations in colors caused by the noise ?
also have any of u guys used a AJA Kona card to capture HD-SDI signals, and what does modul8 do to a 1080i or 720p signal, it seems to me that even if the output resolution through DVI is higher than 1080p resolution (1920x1080) Modul8 still seems to downconvert my HD-SDI input to SD resolution, is there a way to keep my native HD resolution to work with as a live signal (playback of HD QT clips is fine it seems)
thanks for the help
