Live Source Mode...
For this screen
shot, I connected my mini-DV camcorder by firewire and turned it to the record
mode for a live source. My other option is a Camtasia screen
capture app, one I couldn't make appear in the
For file sources, I
reached over to one of the files in my library. You can toggle among
the sources when outputting a streaming video.
The Encoder is
streaming the currently selected video out my port 8080... to whoever
is tuned in. Select the option in the metadata area and it'll
save an archive copy of the broadcast as a wmv file as it
broadcasts. The path to one of my archive files is...

Video Filters... Compatibility
We're all too familiar with issues with codecs when doing video
The compatibility list is somewhat comforting in being able to stop a
specific filter from effecting the process without disabling any apps that use
The Tools > Options choice on the menu... in either mode... gets
you to the list.
Linger over a line item to see the tooltip for the full path and file
The sort order is by Name, and you can't change it by clicking on any of
the column headers.
Markers and Thumbnails
Exiting Live mode, let's look at a couple selected features,
starting with markers and thumbnails.
The Expression Encoder has a feature to set chapter points,
and the Silverlight packages let viewers use them for control...
Set the markers at the frames you want, and then opt for
thumbnails... at all markers or just selected ones. Checking the top option like
I did selects them all.
When the file is playing in a Silverlight package such as the
'Clean' style, move your mouse over the upper part and the chapter
points with thumbnails will appear... click on one to move to
that part of the video.
If your overlay image has a solid background, select the
option to Use Transparent Background
to remove it. This
command samples the pixel color at the 0,0 coordinates of your image, which is
in the upper-left corner, and removes that color from the image.
Here's a BMP image, a 3D URL on a blue background...
the blueness turned transparent when the option was selected. This
opens the making of such transparent overlays to all image apps that can make a
solid color background. You don't need anything more than Paint.
Closing... and What's Next?
had a chance to exercise the compatibility list items yet, as the Expression
Encoder works well on both my XP and Vista laptops with whatever input
files I use.
there hasn't been any issues playing the online Silverlight packages
produced by the Encoder.
I find the
