Step 1: Go to File > Import > File in your Affect Effects and add the video to the project. ![]() If you want to blur a face in the video, this feature could detect the face outline automatically. It contains extensive video editing features, including track faces using artificial intelligence technology.

These keywords were added by machine and not by the authors. Based on a relatively large testing material, we show experimental results on the motion blur and noise behavior in different illumination conditions and their effect on the perceived image quality. Similarly, necessary measurement methods for image noise are presented. A motion blur metric is created and analyzed. In relation to digital photography the interesting question is: What is the tradeoff between motion blur and noise that is preferred by human observers? In this paper we explore this problem. However, at the same time also noise will be amplified. Loss of image brightness caused by shorter exposure time and consequent underexposure can be compensated with analogue or digital gains. On the other hand, risk of motion blur due to tremble of hands or subject motion increases as exposure time becomes longer. Long exposure time is required in low illumination level in order to obtain adequate signal to noise ratio. In low light conditions, the image quality is always a tradeoff between motion blur and noise. Motion blur and signal noise are probably the two most dominant sources of image quality degradation in digital imaging.
