Welcome to Geekhack!
Sorry, can't help you. I struggle with Adobe Premiere and am a anaglyph noob.
Plus, are you SURE you want the wedding in 3D? I find it works best for porn.
haha, yes, for porn too) The thing is that my sister hired an event agency for her wedding and the whole event will be in the format of shooting an action film. What I heard there will be elements of racing etc. So the outcome can be actually appropriate for using 3D.
On other forum I was advised to hire a 3D camera and don't mess with the conversion. Will check for prices, if it's not very expensive I will go for it. But anyway I found that 2D to 3D anaglyph conversion software, so will try it anyway out of curiosity.
Thanks for your reply anyway)
