Setting Preview Quality on Canvas

To enable high-performance editing, go to Settings.

Editing on Low mode will give a low-quality preview on the canvas, but will allow for smoother editing.  
Editing in Low mode will not affect the quality of the rendered video. Videos will still be published according to your selected resolution.

Switching to High Editing Mode will give a high-quality preview on the canvas, but you can expect the editor to slow down a bit.

Note: High Mode only works for assets that are from the CreateStudio Pro library. It does not apply to imported media.
