Frame Rate 101

Frame rate is the frequency at which an imaging device produces unique consecutive images known as frames. This term applies to visual mediums such as video, film, and computer graphics. In general, the higher the frame, the smoother the motion will appear but the more processing power and system bandwidth is required. Frame rate is measured in frames per second (fps).

In motion pictures and television, the frame rates are standardized by the Society of Motion Picture and Television Editors (SMPTE). Frame rates of 24, 25, and 30 frames per second are common, each having different uses in different parts of the industry. For example, 24fps is often used in the film industry while 30fps is used in U.S. television production.

Despite the growth in popularity of web video, there still isn’t a “standard” frame rate for online playback. This is mainly due to several other factors impacting quality and file size such as data rate, frame size, color bit depth, keyframe settings, codec options, etc. Even the content being displayed in the video can impact how it looks. An action-packed sequence with lots of quick cuts and fast motion will most likely need different compression settings than a single person interview in a well-lit studio.

At DDA Video, we are well aware of the best usages of video frame rate whether we are creating promotional DVDs or CD-ROMs, mastering high quality medical Blu-Ray discs, exporting web based e-Learning tools,  rendering 2-D and 3-D animations, or even developing new state-of-the-art Virtual Medical Simulations (VMS). We know what it takes to make you and your product/service look good!
