how to use the clocked video input IP in SOPC

the demo example 's input data is 8 bits width, but the itu656 interface is 10 bits,the least 2 bits are not used.

in my design , i want to use the clocked video input and clock video output, and the data 's width is 10(SDI) or 20(HD-SDI) bits, what shall i set the parameter.

i still donn't know how to set the input and output 's width to 10 or 20, because if i set to these value , the SOPC will give an error, it said the interface can only be 8 bit width.

for example, use the test pattern generator to generate the video content(color bar) and use the clocked video output to ourput the video and use the sdi interface serialize the video. the data width is a problem.

do i have to write a compent to connect the two component with different data width?
