If there’s a lot of background noise, it can also help remove this. PowerDirector can also do clever tricks with sound, detecting when a person is speaking and then enhancing it. The tool can also be used for masking, letting you easily isolate an object or person, so you can either remove them from the video, or keep the subject and remove or alter the background, such as the sky effect in the screenshot below. As that object moves, so will the text or other graphic you’ve applied. For example, the motion-tracking tool lets you create text boxes or other graphics, then assign them to something or someone on screen. Some of the best new tools use algorithms to detect people and objects in your videos, then apply effects directly to them. There are plenty of other new features that existing users will notice. This is the first version of the software to support 4K video, so if your camera or smartphone records video at that resolution, it’s well worth the upgrade. “New features include tools to detect people and objects in videos”
