Hi,
First, I would like to move the buttons outside of the viewer so that they don't obstruct the view.
do you mean outside the krpano viewer?
That's not possible inside the viewer, but you can create buttons in HTML and then call krpano actions via Javascript.

Second, I would like to start the video on a specific frame.
The seek() action of the videoplayer plugin can be used to seek to a specific time in a video (specific frame access is not possible, Flash and HTML5 provide only access to the time):

Best regards,
