Ok, so now I have workin capture.

But somehow every time I starting recording, this decklink's card gives me
color bars for few frames.

So is there a way how to tell ffmpeg that skip first 10 frames and after
that start record the stream. 

Now I use this command:

bmdcapture -m 2 -C 0 -A 2 -V 4 -F nut -f pipe:1 |ffmpeg -re -i - -copyts -r
25 -aspect 16:9 -copyts -vcodec libx264  -vprofile main -preset medium -crf
17  -s 640x360 -b:a 196k -ar 44100 -b:v 1100k -maxrate 1300k -bufsize 1500k 
-pix_fmt yuv420p  -y /tmp/testfile.mp4

Thanks for your help advanced.
Ans if you have ideas how to make better quolity I'm pleased to hear any
