Hi Kian,

I believe you are correct. Our DDR4 is already maxed out at 1200 MHz and from my calculations I believe we are using nearly all of our bandwidth, like around 98%. Do you have any recommendations on what video format I should use? The reason we are navigating away from YCbCr is because our chroma keyer feature cannot handle small detailed graphics. There is always a residual green spill leftover from detailed graphics. The only thing we could think to do to accommodate for this was switching to RGBA, which is why I started conducting those RGB tests with the frame buffers. I will attach a image of the green spill I am talking about. Thank you again for your time and help!


Thank you,

Evan
