Hi,

According to the vip_user guide, the latency of clipper is 0 cycle. So I think it's transparent to CVI and Scaler.

I have a hint for you that when it doesn't work, you may observe that whether an overflow or underflow happened, and try to find out where the dataflow is blocked from that.

By the way, you can use the sinagtap to observe the status signal of each block.
