Reader Dave Da would like more information on what he can and can’t do with his video files. He writes:
Is there any software out there that has the basic function of allowing you to change visual settings such as contrast, sharpness and every other imaginable one and saving the video file with the new settings?
While I’m not sure I’d call changing every imaginable visual setting “basic,” I take your point. The answer is yes and, best of all, the foundation for this lies within software you probably already own: iMovie.
All you need to is capture your video with iMovie, select the portion of it you want to change, click iMovie'’ Effects tab, and assign the effect you want. Within iMovie you’ll find controls for adjusting colors and changing brightness and contrast. iMovie can impose more exotic effects with the assistance of third-party plug-ins. Effects plug-ins from such companies as GeeThree, Vertix, cf/x, and Stupendous Software get darned close to providing you with that “every other imaginable” effect you desire.
