Movie File Formats
WMV
Although there are many different media container
formats, the ones listed here are the ones you will
most frequently run into. While some solely support FLV MOV
audio, others also support both audio and video.
MPEG-4 (MP4), QuickTime Movie (MOV), and the
Wavefile Audio File (WAV) Format are the most widely
used media containers on the internet.
AVI MP4

AVIs are compressed movies that can be viewed in Windows systems
with Media Player and on Unix workstations with Xanim player.
.flc, .fli An FLC is a raw, uncompressed collection of frames from an Autodesk
Flick video. Despite having a larger file size than other formats, they
have better image quality. Media Player on Windows can be used to
play them.
