I’m trying to record madmapper 1.2 composition output to projector 800×600. The idea is to record output with mapping and then play that predistorted video over the mapping object via a normal video player without use of madmapper. The problem I encountered is that after I set custom dimensions 800×600 for syphone recorder in preferences and make the recording I got the recorded video of 800×768 despite settings I made. I tried different codecs but it doesnt work aswell: I got same 800×768 instead of 800×600. Seems like some forced aspect ratio or smth. Could anyone be so kind to help me with this issue?
