any of you video wizards tested the Blackmagic DeckLink SDI or Duo card?
on our current project we use them, but when a dark object moves in front of a bright background we notice a wired after/ghost image behind it. this gives the impression as if the card operates too slow or. its the same with 1080 50i and 1080 25p format.
we tried a lot of stuff, like changing the screens, different exposure times of the camera and so on… but eventually came to the conclusion, that it has to be the capture card. can anyone confirm that?
I can’t. We used Decklink SDI card for capture and everything worked fine, but i’m not sure that we had a big brightness difference between front object and background. How you grabbing the image from camera? DShow or native plugin?
I’m don’t know, where this preferences in VLC. But it’s usual DShow filter settings window, you can find it in Virtual Dub by pressing - File, Capture AVI, Device - select your device, Video - Capture Filter.
Also Virtual Dub is good for live capture testing.
