We recently filmed some speaker presentations for a client. In addition to the DVDs, they would like to have a variety of web versions available. They requested Quicktime Movies (MOV), MP4 files, and WMV files, in order to cover all their bases. We were able to provide all the formats they needed, but it brings up a serious issue in today's video world. There are literally hundreds of playback formats, and playback compatibility is a real issue. There was a time when MPG1 was the universal compressed playback format that could play on anything. That was a nice thing, although it had its limitations. I hope that one day the standards consortium will be able to agree on a universal playback format again.
