Decklink Transiton MIX NOT APLIED

Hello
I want to play decklink input with transiton mix at 30 frm but it doesnt happen
Videos and images take this transition but the blackmagic declink input no.
How can i fix this ?
Thank you

The decklink input will produce some black frames before the input signal, which could be what you are seeing.

Try doing something like the following, with a second or so wait between the commands

LOADBG 1-10 DECKLINK 1 MIX 30
PLAY 1-10

thank you very much

please how to apply this commands ? i dont have much knowledge about costum commands

You dont need to use a custom command for this, in the client you can simply press F3 (load) on the item then F2 (play) to produce the same commands

thanks very much
