We offer two high-quality formats for each of the video resources - H.264 and Mpeg-1.
Mpeg-1 is a large file size but is compatible with both Windows and Mac computers using either Windows Media Player or Quicktime. We recommend this format for presentation software (PowerPoint, MediaShout, Keynote)
H.264 is typically a smaller file size but is actually a higher quality than the Mpeg-1 version. It can be used on both Windows and Mac computers, but it requires the latest versions of Quicktime and Windows Media Player to play reliably.
