On Max 7.0.4 there is "jit.grab: native Blackmagic driver implementation "

With jit.grab it says as the object is created

so asking getdevlist umenu fulls up with 4 times DeckLink SDI [native] nothing with getinputlist

Running metro and open grab doesn't show any image...

So where to start to make it run in jitter???

Hello dear list,
On Max 7.0.4 there is "jit.grab: native Blackmagic driver implementation "
With jit.grab it says as the object is created
Blackmagic DeckLinkAPI version: 10.4.1
so asking getdevlist umenu fulls up with 4 times DeckLink SDI [native] nothing with  getinputlist
Running metro and open grab doesn't show any image...
Using Modul8 every 4 inputs runs fine...
So where to start to make it run in jitter???
Any ideas are welcome
Thank you
Cheers

please let me know what is printed to the max console after you:

2 - start your renderer and bang the jit.grab object

by default, the native blackmagic device will try and find an appropriate format automatically. however if this isn't working you can set the format manually via the @format attribute and getformatlist method. patch below demonstrates this:

are you sure there's a valid video stream going through the card? blackmagic cards are very particular about which formats they accept. make sure your device is on and outputting the proper format, and make sure you've enabled the input you're sending to via the blackmagic desktop app.

you can sending "format -1" again to force it to search again for a valid input format, or you can try selecting the formats from the list manually.

are you able to see an image when you launch another blackmagic app? if so, note what input format it is using, and then select that manually in max.
