In case you want to combine a 4:3 source with an 16:9 source you need to adjust the MultiView settings to get the following output:



  • Click on the settings icon of the Side-by-Side preview
  • Click on Multi View in the left menu panel
  • Click on Position of the source 1



Now we are changing the  Zoom and Pan X values


  • Change Zoom into 0.57
  • Change Pan X into =-0.57


  • Now select Overlay 2



  • Change Zoom into 0.57
  • Change Pan X into =0.43



16:9 and 4:3

In case you want 16:9 on the left side and 4:3 on the right side you need slightly different settings


Overlay1


  • Change Zoom into 0.57
  • Change Pan X into =-0.43



Overlay2


  • Change Zoom into 0.57
  • Change Pan X into =0.57



Note:  Do not change the Main zoom/pan settings otherwise the automatic slide detection will not work.
