If you decouple the input and the FIR with Framebuffers like I recommended for first tests, the frequencys should be okay.

but if you have no decoupling around the FIR, this is not enough, it is an easy calculation:

pixelclock for 720p is 74.25MHz, if you have for example RGB as colorspace, you will get 3 colorplanes per tick, if you try to process them in sequence you will need 3 times the pixelclock to be safe, which is quite to much for the whole pipeline.
