The image of adv7511 output is reddish. Software is offerred by ADI. The Sch is on attachment.
Either the Zynq is not outputting the correct chroma values or the 7511 is not configured for the right color via the scripts. Compare your scripts against the default script files for the 7511
The schematic look reasonable.

I run example above, and the result is as attachment.
Looks like you have a color space issue. How are you initializing the ADV7511. I am not familiar with the GitHub code. Are you sure the Zynq output format matches what the 7511 input is programmed for.
I run the example offered by ADI. I think the initial is the Func ADIAPI_TransmitterInit in transmitter.c.
