Hello all,

As many of you know I have been working on my own custom LSP export tool.  This tool is intended to export sequences created with LSP 2.5 to xLights and Conductor file formats.  In addition it can also be used to combine a set of smaller sequences into one larger sequence.  This particular use case can be very handy if you are using very high channel count shows.  Some users have reported issues with LSP running out of memory when working with many thousands of channels and video transitions.  Some of us work around this by breaking a song up into 20 second segments and then exporting each segment and recombining those segments into one final sequence to display.  As you can imagine that was a long and tedious process. 

I created the Light Elf to make that particular workflow easier to perform and potentially help anyone that wants to use xLights or the Conductor to run their show.

How to use:
 
First the Pre reqs:
!!!IMPORTANT!!! Make sure you are consistent with what version of the below libraries you download.  Python and wxPython must both be compiled for the same word length, be it 32bit or 64bit.

Install python 2.7: You are not allowed to view links. Register or Login  --Don't use anything later than 2.7.x
Install wxPython: (Direct Download) You are not allowed to view links. Register or Login

Install xLights and define your xlights network layout : You are not allowed to view links. Register or Login

Extract the file "light elf.zip" (Attached)

EDIT: Have moved to store light elf on git hub.  You can always check for the most recent version here:
You are not allowed to view links. Register or Login

launch a command line prompt in the directory created by the extraction (shortcut: in windows 7 hold the left shift key and right click on the directory. select "open command window here" from the resulting menu)
 
issue the command:
C:\python27\python.exe "light elf app.py"
 
Usage:
under sequences menu chose add sequences.
add the sequences you want to convert (If you plan to combine only add the files you want to combine, make sure they are in alphabetic order)
under options you can pick individual sequence conversion (each file becomes its own file) or combine (all are made into one file)
when all the sequences are converted you can go to file-> export.

You will be prompted to specify which file formats you want to have generated for you.

Under Options->settings you can specify a non default directory for where Xlights holds the information specific to your comupter.  You can also specify a directory used for the storing the extracted versions of your LSP sequences.  This can make it easier to cleanup the excess files created from extracting the LSP sequences.

If you are in combine mode you should get a pop up to select the media file you want to use.
If you select combine it should be the selected option when you restart the app.
 
The app will spawn sub processes 1 per cpu core you have in your system.  Each process will convert one sequence to use as much processing power as possible.

There you go.  I hope that people find this tool useful.

Best Regards,

Frank

Steve Gase:
Thanks for doing this frank! 

rdebolt:
+1 Have used in the past and saved my bacon last year a couple of times.

Steve Gase:
Frank, now that you are working on Nutcracker is there any chance that you'll incorporate Light Elf capabilities into Nutcracker to simplify the overall procedure?
 
thx!

At the moment it is not high on my priority list.  While the code is pretty straight forward in python doing it in C++ has more than a few hurdles that would need to be tackled.  While it is not outside the realm of possibility that it will happen some day, it will in all likelihood not happen for this season.
