t
MPEG2
: This older file format is primarily used for DVD and Blu-ray Discs. 
Presets in this group allow you to produce files that can be distributed for 
playback on your own or other computers, but H.264 generally produces better 
quality at a smaller file size.
t
MPEG2-DVD and MPEG2 Blu-ray
: These formats are to be used when 
producing files for burning onto an optical disc.
t
Windows Media
: This option produces MWV files for playback using the 
Windows Media Player and on some devices like the Zune (Windows only).
That’s only a brief overview of the formats, but it should provide some useful direc-
tion when it’s time to produce your videos.

LESSON 20 Exporting Frames, Clips, and Sequences
Using the formats
Let’s reverse this approach and take a user-centric view, identifying the use of 
the video and then pointing toward a format and preset. There are few absolutes, 
but these should get you in the ballpark. Just to state the blindingly obvious, try 
whatever option you choose with a short file first to test the workflow, before going 
live with it.

Uploading to a web site for Flash deployment
: When you choose the FLV|F4V 
format, choose an FLV preset for producing the file with the older On2 VP6 
codec, and choose F4V for the newer, higher-quality H.264 format. If you don’t 
know which format to use, go with F4V. In terms of resolution, the 720p Source, 
Half Size presets in both F4V and FLV formats encode your video at 740x360 
(for HD source), which is a nice conservative resolution that should look quite 
good. Check with your web administrator for the format, resolution, data rate, 
and other details.
