Video appears to be moving because there are so many images appearing each second that your brain is fooled into thinking they are one continuous image that's changing over time. The question is, how many frames is enough? And once you know that number, why would you capture more frames each second than you need? This video explains the fundamentals.
- [Instructor] The frame rate of your footage,…animation, or motion graphic,…is the number of frames per second.…This applies to recording footage in a camera,…editing, and playback.…As long as the recording speed and the playback speed match,…movement will appear to be natural.…It'll be the same as it was when recorded.…In the early years of cinema, slow motion effects…were achieved by capturing more frames per second…than would be played,…and since cameras were operated by a crank handle,…this was called "Over-Cranking",…and the phrase is still used today,…even though the image is usually captured digitally.…
Interestingly, even though we're working with data now,…rather than silver halide on celluloid,…the principles of capturing a resemblance of a scene…and representing it for human vision,…haven't changed even slightly.…We have the same challenges,…and many of the same kinds of solutions.…We're just doing things with data instead of physical film.…Focus, exposure, and frame rate, apply just as much today…
Get ready to remove the mystery behind terms you've encountered. If you work in a creative profession, this can enhance your command of the tools you use. Learn what a pixel really is, what color channels are, and what audio frequency is. Discover how color channels, bit depth, and video frame rates work. Find out the difference between codecs and file formats, and how compression is involved. By the end of this course, you'll know how to answer common client questions—like, whether a logo should be supplied in vector or bitmap form, and more.
