AVI (compressed with any available compressors
on the user's machine)Formats of Multimedia Output Files
The LEADTOOLS Multimedia Features writes the following file formats:
AVI (compressed with any available compressors
on the user's machine)
Mpeg1 Layer-3 Audio (MP3)
MPEG1
System (video and audio) This requires the use of an MPEG1-compatible
audio and video compressor Also known as an encoder, this is a module or algorithm to compress
data. Playing that data back requires a decompressor, or decoder.

and LEAD MPEG2 Video Encoder can be used. (The LEAD MPEG2 Video Encoder
can generate MPEG1-compatible video compression.)
MPEG2
Program (video and audio) This requires the use of an MPEG2-compatible
audio and video compressor. The LEAD MPEG Audio Encoder, LEAD
AC3 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.
Audio Codec Software component that compresses and decompresses audio. Codec stands
for COmpressor and DECompressor.

H264 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.
Video Encoder can be used.
MPEG2 Transport (video

compressor. The
LEAD MPEG Audio Encoder, LEAD AC3 Audio Encoder, LEAD
MPEG2 Video Encoder, LEAD MPEG4 Video Encoder, and LEAD H264 Video Encoder
can be used.
