The LEAD AC3 Audio Codec is a DirectShow filter that supports the encoding of audio streams using the AC3 standard. The LEAD AC3 encoder provides options to control the quality and the number of output channels. AC3 is a 5.1 format, which means that it provides five full bandwidth channels: front left, front right, center, surround left, and surround right. A low-frequency effect (LFE) channels is included for the sound needed for special effects and action sequences in movies. AC3 also has a downmixing feature that ensures compatibility with devices that do not support the 5.1 format.

Software component that compresses and decompresses audio. Codec stands for COmpressor and DECompressor.

LEAD H264 is a DirectShow filter for compressing and decompressing Video data using the H264/AVC standard. H264 is the latest video standard developed jointly by ITUand MPEG. H264/AVC provides a far more efficient algorithm for compressing video.It typically outperforms all existing standards by a factor of three to four especiallyin comparison to MPEG-2.

[Flash Version 6 format. Uses the FLV multiplexer, H.263 video compression and MP3 audio compression]

[Flash Version 9 format. Also known as 'Flash HD', it uses the ISO multiplexer, H.264 video compression and AAC audio compression]
