Resolution for customframe and story size

Hi,

I have developed custom frame using Articulate Storyline SDK, due to resolution conflict the output was cropped L

I have used resolution for custom frame stage size as 980*640 and movieclip size for slideContainer as 950*480. The story size as slideContainer value i.e.  950*480. In the output the custom frame footer navigation get cropped L

Anyone know what could be the problem
