H.263 is an ITU standard, designed for low bit rate communications such as video-conferencing and video-telephony applications. At the same time it can be used for a wide range of bit rates and not just low bit rates. H.263 is a hybrid of interframe compression that makes use of temporal redundancy and intraframe transform coding to use spatial redundancy as a compression advantage. Accordingly, a superior compression ratio can be achieved in comparison to other video codecs.
The LEAD H.263 codec is a high quality lossy interframe DirectShow® and Video for Windows (VfW) codec with a quality and compression ratio comparable to MPEG-4. It can be used for a range of applications including video-conferencing, Internet video or surveillance and monitoring. The LEAD H.263 codec is suitable for videos captured from cameras as well as video screen captures. This video codec registers into the Windows collection of multimedia drivers and integrates with any application using DirectShow® and Microsoft Video for Windows. Existing video software, such as Windows Media Player and Ulead Media Studio can utilize this codec to play, create, convert and edit.
The LEAD H.263 Video Codec Module contains DirectShow® filters and codecs that allows an H.263 file to be played, or files with other file formats to be converted to H.263 files.
