Just wondering where everyone gets there video files from. Started playing with this last night. The out line and photo shop part was pretty easy now just need to get all the video parts together.
ok so i made my trace, in windows paint set the properties to 1024x768. screen res is the same . when i bring this image into serif set the project to the same 1024x768 when i look at the full screen video on the house the image dont line up like it did in paint the right side is short if that makes scene any idea on what the issue could be.
Ok thanks i will look into that tonight
I was wondering how the mapping went and if you have any video from Halloween night
He's building WWHHAATT??
Hi Icepick, great tutorial. I have a few questions if I may:
Firstly, like Icepick, my wife and I go yearly to Disney albeit DLP (Disney Land Paris in France) and we were blown away by the Disney Dreams night show that transforms the castle.
I understand the importance to setting your computer’s resolution to the same as the projector’s native resolution to do the trace of the house.
My current projector (NEC MT106) whilst good as it has 2,600 ANSI lumens, native resolution of 1024 x 768 (XGA) but a throw ratio of approximately 1.5:1 so I’d have to position it across the road to get the effect. I will have to get another projector with a shorter throw ratio.
Question 1: After doing 3D trace do you set your computer back to default resolution?
Once you have done the trace and you’re back inside using your image editing program to make masks do you need to keep the computer’s resolution the same the projector’s native resolution or can you reset the computer back to its default resolution.
Question 2: Best cost effective native resolution?
As I need to get another projector but this time a short throw one, apart from good ANSI lumens, what native resolution should I go for. i.e 1024 x 768, 1280 x 800, or 1920 x 1080? OK that might be a silly question as on paper 1920 x 1080 is better but on terms of projection mapping is there much difference between 1280 x 800 and 1920 x 1080 or even 1024 x 768? Bearing in mind that a higher native resolution is going to cost more.
Question 3: If you upgrade projector do you need to redo 3D trace and start again?
If I bought a 1280 x 800 native resolution projector and used it for a few years and then when prices drop bought a 1920 x 1080 native resolution projector would I need to start from scratch, i.e.redo the 3D trace etc?
Question 2 isn't one I can really help with. Of course I want to say go with a 10000 plus lumen, 1920x1080 ultra short throw. But I know everyone has a budget. All I can recommend is to buy what you can afford. Resolution is more important than lumens to me, but that means nothing if people can't see it. Base your lumens on you r ambient lighting. My first year, I used a 1100 lumen machine and it worked just fine.
Question three is an absolute yes, a new map will be needed if you change projectors. The good news is, is that the mapping is the easy part. Going through all your created content to resize and adjust to fit the new projector is the hard part. for me, this is where labeling my video tracks properly helped. Your house won't change so it's just adjusting the actual video track to fit to the new map.
If I missed anything let me know, or if you have any more questions.
