Honored Contributor --- Quote Start --- Are your four video inputs to the FPGA synchronized to each other? --- Quote End --- The inputs are the same at each CVI, I splitted the source signal out of the SOPC Builder. Input => SOPC System => Self Programmed Mixer => Output SOPC System: CVI - Clipper - FrameBuffer - Scaler - CVO CVI - Clipper - FrameBuffer - Scaler - CVO CVI - Clipper - FrameBuffer - Scaler - CVO I clipped different parts of the video and have scaled them up. If I clipp always the same parts of a videostream, I get only an offset of a few pixels, which I can compensate by a self written Verilog code. But when I clipp different parts, i get an offset of around ~50% of all lines
