Why legalize?

Throughout our exercises today, we have done a lot to adjust the overall…exposure and contrast in our images.…When you make these types of adjustments, it's quite possible to create an image…that's no longer broadcast-safe.…This means that if you're using traditional output, such as tape, or going to a…broadcaster, your video may be noncompliant.…It becomes necessary to adjust the images to ensure a better overall…signal that's compliant with standards that are used throughout the…broadcasting community.…These standards also affect things like compressions, duplication, dubs, lots of things.…

So even though you may not be working with an on-air workflow in mind, you…still need to be conscientious about limiting your effects so they follow…broadcast-safe standards.…
