Dear developers,
dear colleagues,

I am looking to visualize a brain mask on the brain and render a video.
The video comes out fine, right was I was looking for. 
However, the quality of the video is low, dimensions are 735 x 534.
Is there a way to change the dimensions (e.g. to FULL HD or higher) to improve the resolution of the video?

Your help is very much appreciated.

With best regards,
Alexis Zarucha
