video playback problems in impress

I’m using LibreOffice 5.1.6.2 and what I’m trying to do is embed video into an Impress Presentation. I’ve tried multiple formats and found info online saying that using ogg video (.ogv) would work best, so I’ve done that. When in editing mode the video will preview just fine, no issues. No problems at all with any other slides in the presentation, but once I get to the video slide the audio plays just fine, but the video gets huge, like it zooms in, starts stuttering. I have installed the gstreamer backend and I’m not aware of any dependencies that I’m missing. I’ve searched online for a solution and haven’t found one yet. Figured it was time to ask and see what happens. Thanks!
