PowerPoint 2010 Video Pipeline: Embedded video file sizes
Logic: understand video impacts on file size
An important part of presentation creation and
distribution is to understand the impact of inserting videos into
PowerPoint 2010 on file size. Let's go through some information I
presented in San Diego at the Presentation Summit.
Option 1: an embedded video- video is 25
meg and uncompressed

PowerPoint adds the video and adds very little
else to the file size- very efficient.
|Add bevel and 3d perspective effects to the
same video, and
save = 25,688 Kb. When you add the effects, only a couple of lines of internal code are
added to tell PowerPoint what the video will look like.
Because the original video is still unmodified (which also
means you undo the effects), the file size increase
is tiny- very efficient.
Let's now start again and look at trimming
video. we will commence again with a 25 meg video embedded
in PowerPoint 2010.
