created the pdf video file

I have one doubt here. I have created the pdf video file.

The video height & width size will be given by the user 8 * 6(W*H)

In my mac system the size same. But in the other system the size is showing 6*4

I don't know the resolution will make this problem.

I have attached the pdf file along this mail.

Step 1

Close the popup first having the text (Check your setting first)

Click on the watch button on top right

Popup will come on top on that click on (trust always) then the video play.

The video width will be 8 and height will be 6. this size is diffrent in each monitor.

My question is the width and height will differ based on the resolution?enter image description here
