Very easy in Vegas...pull it into your timeline...rightclick on the clip...select "video event Pan/Crop"...a child window will open...rightclick on the image area...select 'flip vertical'...rightclick again and select 'flip horizonal'...done!
Haven't used it in about a year...can't help there...sorry.
(once I started using Vegas, there was no going back. IMHO it's a much easier, faster program to use)
