Thanks for your reply. I am saving the video files as anaglyph AVCHD on my computer and uploading them to YouTube.
The reason that I am interested in FCP is that I had been using Vegas Movie Studio 14 Platinum because it supports 3D AVCHD. When that version stopped working, I upgraded to Movie Studio 16 (standard) and it wouldn't allow me delete clips from the timeline without automatically deleting them from the project bin. That bug makes it nearly impossible to edit. I found out from Vegas tech support that I needed to upgrade to Movie Studio 16 Platinum to be able to have the same functionality that I was used to in Movie Studio 14 Platinum. All of that hassle has me wondering if FCP would be an easier option for creating anaglyph 3D videos.
