Videodrome

I'm looking for a beginner board that can help me 'decimate' progressive to interlaced video signals. No scaling, only removing every other line from every frame and outputting it as an interlaced resolution. Would the extra flipflops and luts on the Z7-20 matter at all in this use case? As in, able to receive and output higher resolutions Or would it not matter and would the Z7-10 be fine?
