I am getting a vertical green line and a grid plane when i try and view my active camera.I am working with the projector effect and planes.Is this a bug or am I doing something wrong
Along with the vertical green line and grid you should be seeing a horizontal red line. This is a normal feature of the Hitfilm interface, since the green line is Y-axis 0 and the red line is X-axis vertical and the grid is there as an aid to placing things in 3D space.
The lower left of the preview window has several toggle buttons. From top to bottom they are Lights, Shadows, Motion Blur, Depth of Field, Grid, Motion Paths. Click the Grid toggle to turn it off when you don't want to see it.
The green line is all the way across my active camera screen.So this is normal?
Yes, if it's toggled on. As Triem23 mentioned, you can toggle it off using the buttons he described.
Ok thanks,that helps me out.It toggles like you say.
