I currently use these batch files to start a Wowza server EC2 instance on Vista 32 bit edition.  I have created shortcuts to the batch files using the following syntax so that the command prompts stay open after a user double clicks the shortcut.

== Technical Notes ==
−
The following batch file will start an Amazon instance and automatically assign your elastic (static) IP address to it after the instance ID is assigned by Amazon.  Just replace any environment or instance preferences and change to your own elastic IP.  The most tricky part of this is the for command which first launches the instance and then extracts the instance id from line 2 (line 1 is skipped), field (token) 2 and assigns the elastic IP address to it.

== How to Create Livesets in VT5 ==
 
−
The most helpful explanation I came across on this topic was [[http://www.newtek.com/forums/showpost.php?p=800416&postcount=8 this forum post]].  I opted to install the Aura plugin and the included tutorial is extremely helpful for getting started.

=== Create a simple picture in picture using Aura ===
 
−
Here are the quick steps for creating an angled picture in picture view with blurred edges (from memory, may not be exactly right):
 
−
# Open a new project in Aura
 
−
# Name the first layer Input
 
−
# Open the liveset brush creator (Filters>LiveSet>LiveSet Brush Creator)
 
−
# Click on the Full Screen Layer button
 
−
# Create a new layer and name it FX
 
−
# In the brush generator set the size to what you want for your picture in picture window and then click Create Brush
 
−
# Optionally if you want to crop the brush follow this steps first
 
−
## Change the view to only show 1 layer (= sign)
 
−
## Stamp the brush onto the blank layer
 
−
## Press the b key to enable the rectangle select tool
 
−
## Select the new cropped brush space you want to use
 
−
## Type shift-k to clear the layer
 
−
# Open Filters>Motion>KeyFramer
 
−
# Check the Preview box
 
−
# Adjust parameters as needed (in this case the H A is changed to 45 degrees)
 
−
# Click Apply Filter
 
−
# Open the blur filter (Blut>Blur)
 
−
# Configure the blur amount (2 in this case)
 
−
# Click Apply Filter
 
−
# Open the LiveSet Generator (Filters>LiveSet>LiveSet Generator
 
−
# Set the Effects Warp Type to Complex (this is required to render the angled video I believe)
 
−
# Name the scene and the shot
 
−
# Click on Create LiveSet
 
−
# Open VT5 and you will now be able to select the LiveSet and shot (the effects bus will display within the pip window
