H.264 (or AVC, Advanced Video Codec) is a video compression codec that is efficient, high quality, and pervasive. Many mobile devices used to display video rely on this codec because despite the small file size it generates, the quality is extremely high. In fact, Blu-ray technology uses H.264 to fit several hours of content onto high definition DVDs.
While H.264 may not be new to the world of digital signage it has never been accepted or offered up as an industry standard, which is unfortunate. It offers many benefits over other codecs, such as very small file size, high quality images even at low bit rates, and broad user acceptance/understanding. It is also natively supported by many, if not most, software video players so it can be adopted with relative ease.
For video based digital signage content, my recommendation is to use H.264/MPEG4 compression at a resolution and bit rate that fits your system. The video files created by MediaServices are always 1280x720, 30FPS, 3MB/s and I must say the quality at such a low bit rate is very well maintained.
