ABSTRACT
There are many common problems with video and filmmakers are bound to run into little snags from time to time, especially if they end up working with others who are inexperienced. The problems can range from noisy footage from shooting in poor conditions, to field issues, and rolling shutter problems. This chapter focuses on uprezzing footage from SD to HD, a common procedure when mixing footage from different sources. The amount of noise depends on a number of factors including the lighting, compression or artifacting, and video format. By removing grain per channel, filmmakers are isolating the channel with the most noise and hopefully preserving the detail in the other channels. Interlaced video comprises two separate fields that make a single frame of video. Rolling shutter is the skew or wobble often seen when something moves quickly in front of a camera or a camera pans quickly.
