Video Formats Introduction

FLV Formats

FLV is the preferred file format for delivering video clips via Flash. It is a specialized file format that has been supported from version 7.

Binary file format that delivers "bitmapped" video, limited to one video and one audio stream per file, over the Internet to one or another versions of the Macromedia Flash Player. FLV content may also be incorporated in SWF files by ActionScript external references.

WMV Formats

Windows Media Video.

Formerly known as .ASF file format from Microsoft. A .WMV file includes a video stream (compressed using MS MPEG4 or WMV1 codec) combined with WMA encoded audio stream. The file format is proprietary and backward incompatible. Currently, dedicated to slow dialup connections, this media format does not allow even sub-VHS video quality due to blurred picture. WMA audio quality, compared to MPEG Layer3 of the same bitrate, isn't better either. You may wish to use Windows Media format to create smallest files that are suitable to send by e-mail, however you must keep in mind that .WMV file works like "one way ticket" - once created, it can't be edited anymore, without horrific quality loss. As opposite, AVI files compressed with MPEG4 video codec are still editable and often it is possible to retain source video quality.
