Digital cinema in 3D has created an opportunity to bring realistic, captivating entertainment to a wider number of cinema screens than ever before, but there are many factors to consider to ensure the best possible presentation with newer digital cinema technology.
Here's a quick guide to help you achieve optimal 3D playback, regardless of the 3D technology being used:
- Ensure that the 3D filter or emitter is in place and connected (to a Dolby® 3D or other system).
- Select 3D Macro on the projector and have your technician verify that the correct projector configuration file (PCF) has been chosen and that the image size and color space are correct.
- Verify that your server is in 3D mode where required.
- Run the test chart that came with the feature to verify that your image is set up and aligned correctly. Check that the active image area is not cropped. In 3D, the image windows can float; the only way to ensure correct setup is to use the test chart.
- Ensure that all the optical elements (lenses, polarizers, filters, port glass, 3D glasses) are clean and clear.
- Check your lamp for any signs of flicker or dimming. Replace the lamp if necessary.
- If you use a circular polarized 3D system, make sure that "ghostbusting" is correctly set up on the server.
- Ingest the feature with sufficient time to do a test run prior to the launch date (Key Delivery Message (KDM) permitting).
- Check your 3D presentations frequently: walk into the auditorium, look, and listen.
- Make sure that your projector and digital cinema system are serviced regularly to maintain the highest presentation quality.
Floating windows grow, shrink, and move to help preserve the onscreen 3D for movies.
Do not mask the 3D image on the screen.
Keep the image aligned. You can do this by using the framing chart that comes with the drive you are screening, if available.
When compensating for keystone, make sure the green lines on the sides and the yellow lines on the bottom are visible.
Do not mask out the green and yellow lines. Doing so will mask the movie's floating windows.
