    Hi, I’m new to brickfilms and I’m learning a lot. What software do you use/recommend for doing greenscreens?

    welcome.
    start with the FAQ, move on the the Resources, and when you’ve digested all that glorious info, THEN come here if you still have specific questions.

    What editing software are you using and what operating system are you currently running?

    I’m working on my first big film so I’m very new here as well. My advice about greenscreen is to avoid it at all costs. It seems like it should be fairly straightforward, but it incredibly difficult and time consuming to get it to look good (in the freely sofware at least.)

    I recommend concentrating on learning stop-motion, storytelling, filming and editing before tackling complex effects. If I could go back in time and start something that didn’t require greenscreen I would but I’m too deep into this film to turn back now.

    There is almost always a way to do what would be a greenscreened fully in camera view. Like if you had a guy floating in the air in front of a backdrop you could just use BSOL to take out whats holding him up and use a piece of cardboard with something printed on it for the background. Can you explain what exactly you are doing and what the shot would include?

    nick_name, what exactly are the problems you encounter with that technique?

    I’m interested because I’m currently doing some tests with a bluecreen, too (preparations for my first film…). Here are two bluescreen stills that I have done. It’s not exactly professional quality but I’m still confident that it will be “good enough” with some more experimenting and will also work for animations:

    What are some good examples for brickfilms with blue/greenscreen technique? I remember the shot in NIS where the two peasants look at the spacecrafts.

    Those stills look pretty good–I’d be interested in seeing the before pics and hearing about your process. I’ll post some details about my bluescreen issues when I’m at home later tonight. Too much typing for work browsing…

    The best brickfilm bluescreening I’ve seen is in Jay Silver’s Rise Of The Empire. Lechnology’s Star Wars movie also has some pretty nice compositing. Leftfield’s The Great Disturbance shows more tyical problems with bluescreening a brickfilm (in an otherwise amazing movie.)

    If you have the bucks, go for Adobe Premiere. NOt only great for video editing, but for visual efects too. It’s a brilliant program, and its certainly worth it just not for the effects, but for the variety of video editing options.

    It has a “Video Transparency” feature, which you could use differnt forms of video transparency for your film (Like a bluescreen, greenscreen, chromakey, screen tool, etc).

    Here

    I have the LE version, and its quite similar… I got my copy for free :)

    EDIT by Moderator
    FAQ 3-6
    Brickfilms is not a wares site, do not ask anyone in the forums for illegally pirated or cracked copies of software.

    Blatantly saying it can be done and encouraging such actions are also unacceptable.

    ^^ heheh :)
    Another tool that you can use is BSOL (blue screen of life). You can find that in the resources section. It’s not as good as Adobe premiere, but it’s not too bad for being free.

    You could also use Master Key. THat is also found in the Resources section.

    This one i heard was good….

    The chromanator also does greenscreening and bluescreening stuff. Cost 90 bucks US

    Here are the before pics:

    I’m using a digital (still) camera for this, I think the higher resolution is advantageous when applying the effect, because the inevitable blue edges around the objects are thinner.

    On the scene with the trees you can see that the tree trunks are transparent, too. This is because this scene was lighted with LED lights which turn out to be blue rather than white…

    The scene/objects are about 40cm away from the blue cardboard which is illuminated with a “daylight” bulb. The spacecraft in the second image is illuminated with a rather yellowish desk lamp. The setup can be seen here:

    I used GUP (Gimp Animation Plugin) to do the masking.

    I’ve been using the Lego Movie Maker for about a year and have figured out how to make it do some things it wasn’t designed for by making my own transparency tga files, inserting multiple still shots to animate special effects. The software you all have cited here is helpful. Wow! the Adobe Premier is expensive so I’ll probably go with something more reasonable.

    mirko: your sample images look great!

    I’m shopping around for a new camera to use… the Lego cam is fine for really basic stuff, but I’m looking now at the cams listed in the resources.
