Perspective change with X Y position change
Posted: Sat Dec 26, 2015 16:45
So I have some logos that are large. I want these logos to spin on the Y axis, in the bottom left corner of my screen. So I reduce the scale and change the X & Y position to that corner. All looks great... until I put a timeline rotation on the Y axis.
As the logo spins (Y Axis), it tilts a bit as if the vertical axis is not straight vertical. So it looks as if Resolume still treats the logo as if it was still centered (full size), but the viewing perspective of that clip is what has changed in order to scale it and move it to that corner. So I have to play with the X & Z rotation a bit to get it to spin on a straight vertical axis (by eye, as close as I can get it). I even limit the timeline so the logo always shows forward. Even these start and stop points are off. so I can't just use -90 deg to +90 deg. I have to tweak those Y axis start and stop points after all the other adjustments so the rotation is smooth.
If this was predictable there would be no issue. But as scale and X & Y position changes for each logo, there is some fine tuning needed for each logo. kind of annoying. So is there a true X & Y screen re position for a clip that dose not shift the vertical axis?
