[SOLVED] Full Video - ideal size of the mp4

I bought the Pro version of the X2 template.
My video looks enormous, with some of it not visible.
Template size is set at 1900 px and video is only at 1024 width.
Setting the template size smaller, to say, 1600 or even 1200, seemed to make the video look even larger...
In the image attached, you can see that some of the video is off the top of the screen.

What is the ideal size for the Full Video source file in the images folder please ?
Or maybe I'm doing something else wrong -
Probably a minor adjustment needed on my end-

Hi there, the video size doesnt matter because it will resized to full screen.
But I recommend a size of 1920 x 1080 ( full HD)

Problem solved.
