So i am trying something out.
i have a server with two DeckLink Quad 2
i have it set up with 4 channels of play back all 1080i59.94 out the first card.
i need to do a squeeze on play back channels 1 and 2. how ever it was not the same set up on each channel.
so i used one of the second cards inputs as and sent it to channel 3 this worked as to be expected i did need to turn on the deinterlacing.
i then used a reroute to send channel 3 to both Chanel 1 and 2.
every thing looked good on out put 1 and 2.
then i used a transform on the live input on 1 and 2.
after the transform i could see the interlacing bad.
to fix this i add a second live in put and routed both to there respective inputs.
why did the reroute create problems for me. it would have been a better way to do what i needed.
