    Lightbulb Masking & Video Production for a Projector the Easy Way

    I know several of you guys are using AE to produce your own videos for projection, and that's fine and dandy; you can create spectacular stuff with it. But I'm not into a Christmas projection project for 20-25 songs that involves the huge amount of time mastering AE takes (although I have it and use it occasionally).

    I just want to enhance and supplement my light show with projection of existing video files and motion backgrounds, tons available for free, easily downloaded, or easily made yourself from your own vid files or photos. I posted a QUICK video on Youtube showing results, and will try to explain the process:

    http://www.youtube.com/watch?v=4WLkK...ature=youtu.be

    1- get a projector. I bought an Optoma GT760 short throw, 3300 lumens, contrast ratio 20,000:1. Short throw so I can get it closer to the house (33 ft, projecting 45' wide, over the house high) and keep it out of my light display area, 3300 lumens which is PLENTY bright, and 20,000:1 contrast ratio for blacker blacks (important for masks) http://www.newegg.com/Product/Produc...82E16824219174

    2- set up a table in front of your house for a computer and projector; adjust the table so your projector covers desired area of house; when accomplished, mark the spot on ground directly below your projector, as you will eventually want to make a permanent mount so your projector lines up perfectly with house each night (I bought an inexpensive ceiling mount and an inexpensive tv wall mount to attach to the projector off ebay; will mount a removable square tube in concrete so it's not up year round, and attach the other piece of tv mount to it so I can quickly mount/dismount the projector each night and take inside)

    3- map your house. I use MS Paint. Trace each area where you are going to want video making sure all the lines touch each other where they should; also trace edges and roofline, as you may want to cover the entire house with a vid sometime (ie, snowflakes). Save the file as a .jpg

    4- open the file in your photo editor (I use Photoshop). Paint the video areas with the paintbucket tool with the exact color of your lines; now in those same areas, use magic eraser tool to delete what you just painted, and it will get rid of the lines too, leaving a transparent background. Save the file as a .png (very important) If you don't know how to do these procedures, check YouTube for tons of tuts

    5- the video editor I use is Powerdirector12; free trial; $99 [edit: on sale at newegg for $39, very limited time; see link in subsequent post] if you buy, also can find sometimes on ebay cheaper. Tons of YouTube tuts, tons of features, 64-bit, multi-processor friendly (I have Mac dual-quad for 8 cores, blazing fast rendering) [edit: I use PD in Windows 7 Pro via bootcamp]. This is not a tutorial on how to use PD, but basically you drag in video, audio, photo files into the channels,, then put your .png mask file last. When you click on an individual channel, it is highlighted in the preview window, and you can not only resize to fit, but stretch/shrink to fit odd sizes (like my triangular gables in the vid) by dragging the blue-dot corners...this ability alone is in software costing 4-5X PD

    6- when finished, you can save to many formats, or create a customized format/size

    I'm sure I forgot something. This is my contribution to the blinky community, so ask questions, I will follow the thread closely. Check out the PD12 tuts on PDtoots on YouTube; also Cyberlink has fantastic forums

    WMM cannot perform complex video editing tasks such as masking, which is the application of a layer(s) over top of the video(s). You COULD create a masking EFFECT by pulling the video apart and reconstructing it, frame by frame. I suppose it could be done, if you have years to spend on it, and in no way would it be "The Easy Way", as this thread was intended...but don't get me wrong, I like FREE as much as anyone...WMM just not a realistic choice for me; I have to spend my time learning blinky-flashy

    Next step will be to figure how to sync with a sequence or sequences?

    Being that you know how to use HLS , this could be accomplished in Ae as you could import your sequence preview and audio to

    make syncing quite easy for your projections .

    I don't currently have AE and based on cloud pricing to obtain same, it is probably not an option for me. Thanks though.

    Falcon Pi Player (FPP) and Falcon Pi Daughterboard (FPD) supposedly already has this capability using xLights/Nutcracker; several tested it over Christmas; I was also told LSP has the capability. I actually have neither yet, as I'm new to all this blinky. And there may be other solutions also. I would welcome any input.

    Well, after a month of looking at projectors, bidding on various units on Ebay and then hoping I get outbid as I once again decided that, another choice is better I finally pulled the trigger and ordered a new Optoma GT760 just as Bob (Poolprousa) did. My criteria were:

    1. at least 3000 lumens
    2. higher contrast
    3. Must be able to cover my garage end of the house in less than 25 feet, 15 preferable
    4. Compared Foot lamberts - All are expresses in video/gaming mode - presentation mode will usually be twice as high.
    5. Keystoning/lens correction capability

    Below are units I considered or bid on.
