Have you ever seen a commercial where an important piece of information, such as a website or phone number, wasn’t fully displayed on the screen? This is a big problem that not nearly enough production companies pay attention to. The issue here is that footage isn’t being edited with respect to Center Cut Protection.
What’s Center Cut Protection?
Great question! This applies to Standard Definition footage that was filmed in High Definition. HD is meant to be viewed in 16:9 aspect ratio, however SD is only 4:3. So since many SD channels still exist, footage edited in HD need to be down converted in order to be aired on these channels. Specifically, Center Cut Protection refers to graphics or text that’s edited into commercial spots. In the photo on the left, you can see how HD footage is supposed to be viewed, with the website clearly within the safe areas. The photo on the left, however, shows how that same footage would be viewed on an SD channel. In this medium, the website gets cut off.
How do I fix CCP errors?
It’s important to be cognizant of title safe and action safe areas. These are lines that indicate that what’s within the boundaries will be completely viewable by audiences. Anything outside is at risk of being cut off depending on the viewers’ TV. These areas differ for HD and SD.
In this photo, the outer line is the Action Safe area and the inner is the Title Safe area. The tiny vertical dashes on each line represent the Center Cut Protection.
I’m sure that at some point you’ve been watching TV and the screen appeared like the one above, with black bars on the top and bottom. This is to keep HD in 16:9 aspect, even though it’s being displayed in a 4:3 frame. Some channels want to get rid of these bars and adjust the picture to 4:3, like the photo below.
In this photo, the blue lines coincide with the small dashes in the first photo. This is why it’s important to stick to Center Cut Protection when editing for SD. Because while your normal safe boundaries may be ok for HD, when that same footage is viewed in SD you may lose important information. This makes the commercial less credible, and thus, your company in the eyes of your client.
