I have Movie Studio Platinum 15.0 to Edit and Make my Videos.

I do go to the Magix WebSite and Log In but it is so Hard to Find and use the WebSite to Post and get help.

I have a lot of Videos some are 1080 HD some are 720 HD and so on.
So I found this video on YouTube that Tells you have to have your Project Preview Winow Match the Video you will Open.

So I know the First Video that you Open the Project Preview Window will Match it to Show you what it Looks like.

But as I Open other Videos will it Force them to Match the First Video and so on?

I hope somby can help me?
