STAGE 3 Rendering Out  When you come to render, you will have to make two separate movies, one for the left and one for the right eye. This is where labling the cameras makes life easy as you don't have to toggle the cameras on/off in the composition, just select which camera you need from the options when outputting.You should now have two quicktimes of the same scene rendered out, one for each eye. Now to combine them in Final Cut Pro. STAGE 4 Final Cut Pro Let us first think about how to display the final 3D result. If you have been to see Avatar or Alice in Wonderland, then you will have worn polarising glasses to make sure the left and right eye image only went to the left or right eye. To do that out of a cinema requires an expensive LCD monitor which I'm sure in 5 years time everybody will have! At the moment I don't have one so for this exercise we are going to use the Anaglyph or Red/blue method. More excellent reading about 3d glasses here There are various methods to combine the two images in FCP using layers, tinting and overlay blend modes. I'm going to make life slightly easier by using a plugin, Stereo 3D Toolbox You don't need a plugin to output 3D, but you do need a plugin to correct any errors such as exposure or alignment differences between 'eyes'.  Here you can see the plugin working in Anaglph mode, which is pretty handy as going full screen on a monitor means you can actually view the movie in 3D for the first time if you have Red/Blue glasses I want to output the video for YouTube which lets you view stereo movies in a variety of ways, not just the Red/Blue method we have seen above. There is one catch, you need to submit the movie in a side by side format. The plugin also has a preset for that too.  Now this plugin is very cool, has a trial period and does allow you to correct images in relation to each other, but you can wing it and go straight to YouTube should you dare. It is fairly easy to put each image in the timeline, shrink the X axis by 50% and position them correctly. One gotcha here is that they need to be reversed, so the left image is on the RHS and vice a versa. I recommend the YouTube 3D Content getting started page
