I just wanted to check to make sure you weren't going to be in for a surprise.
HDMI is, with the exception of very specialized camcorder input cards, a non-recording interface. When you attach an HDMI cable it is designed to go from source to destination, without any recording of the signal on the HDMI cable. One of the things that is supposed to prevent that is called HDCP, which is an encryption scheme (that has been broken) not analog copy protection like Macrovision. The other thing that prevents copying from HDMI is that all of the manufacturers who have signed-up for HDMI licenses have signed in blood that they won't produce anything that can record HDMI, particularly in the U.S.
The exception are the camcorders who don't use encryption in their output. There are PC-based cards that can be used for recording unencrypted output.
HDMI is actually a lousy place to record anyway. The data is uncompressed and can approach 10.2 gbps (although 1080p/60 with audio is about 4 gbps). That's a lot of data to record. A better place to record is at the source where the data is already compressed.
So, I don't think a filter is going to help you with HDMI. I'm not entirely sure about what you are trying to record (and I don't need to know) but I didn't want you to get surprised when you try to find a way to record with HDMI and can't find one with any known manufacturer.
