When using the multimedia package with the beamer class, you must specify the width and height of the movie like this:


The problem is that the video loses quality due to resizing.

How do I make beamer show the video in its original size, i.e. the same size as when I play it in VLC or Media Player?

I tried putting the size of the video in pixels like this:


But beamer displayed it much bigger than it should.

With the media9 package and Adobe Reader you can play video files in a detached window at their natural size. You need to know the video size in pixels and pass it as an argument to the windowed option, e. g.:


]{\strut Click!}{VPlayer.swf}

(Replace myvid.mp4 with your video file, which must be in the H.264 format.)
