I am currently using the Video and Image processing suite version 8.0.
The only component that you need to reconfigure is the clocked video output. This can be done via the avalon interface. The clocked video input will automatically detect format changes and you can check the status via its avalon interface.
Take a look at the documentation for the clocked video output. It's pretty straightforward.
On another note. You might consider not using the clocked video input and output cores for what you are doing. The Color Space Converter is all you really need. I'd just find a way to interface to it without the other components. I'm guessing you could use the CSC core without the Video IP control packets. And of course converting from 4:4:4 to 4:2:2 is trivial.
The other cores are pretty bloated and don't really provide functionality you need.

Thank you Jake!
I did as you suggested. Now I am only instanciating the Color Space Converter without the video input/output. I did a small module to convert from 4:4:4 to 4:2:2 which only discards samples. The Altera resampler has an option to filter the output because it says that only discarding samples can result in aliasing. I don't know if that would be necessary in my case though.
The Color Space Conversion is different for HD and SD signals. As I don't think that there is a dynamic way to change the coefficients of the converter, I instanciated two modules, one for HD and the other for SD. I'll select which one to use based on my input signal.
