Red and blue glasses are used to transmit stereoscopic images to your eyes.
Stereoscopic 3D effects involve transmitting slightly different images of the same scene to each of your eyes. Just like your eyes focus on the same object from a slightly different perspective and combine the two image sources to create depth, so does stereoscopic 3D. While stereoscopic videos may be created in post editing, using proper filming techniques to create 3D video will result in more realistic 3D effects.
Instructions
Filming in 3D
1. Set up your cameras prior to filming the scene. Set the cameras on a flat surface 6 inches apart from one another.
2. Use the protractor to set the center camera at a 90 degree angle from your subject. Set the left camera at a 100 degree angle and the right camera at an 80 degree angle from the center camera. These angles will be used to create the illusion of 3D in your film.
3. Set all three camera to use the same recording settings. This process can be simplified by using the same model camera for all three cameras. The actual settings used are not as important as making sure that all three cameras are using the same settings so that one video stream does not overpower the other in post-processing.
4. Press "Record" on all three cameras and start your scene. Use a movie slate clapper prior to recording any action to help you synchronize the video streams in post-processing. Repeat this process for each of your scenes.
Making Stereoscopic Videos
5. Load each scene from the three cameras into your digital video editor.
6. Label the scenes from the left camera as "Left," the scenes from the right camera as "Right" and the scenes from the center camera as "Center."
7. Color correct your film to create the 3D effect. Color correction alters the red, blue and green elements of your film. Select your "Left" video and open the color correction option under your video editor's "Effects" menu. Set the "Green" and Red" levels to "0." This will create a blue hue to the video. Select your "Right" video and set the "Green" and "Blue" levels to "0." This will create a red hue to your right video. Your 3D glasses will filter the red "Right" layer from your left eye and the blue "Left" layer from your right eye, resulting in a 3D image.
8. Place the "Left" and "Right" videos above your "Center" video on your video editor's editing timeline. Set the opacity of the "Left" and "Right" videos to "50%," making them slightly transparent.
9. Synchronize the video clips using the slate clapper as a reference point. Your video must be synchronized or your 3D effect will not work.
10. Export your video and preview it with your red and blue 3D glasses.
