advanced video mapping

[ATGxQuadPimp]

Once i have created the mask and projected the image back through the projector,how would i get each of the buttons and dials to light up a different color and not all the same video footage?

[deepvisual]

@ATGxQuadPimp either, use different video for each button, or use one video with lots of different coloured areas .. you could globally change these using a filter or the inbuilt color correction in M8

[ATGxQuadPimp]

@deepvisual I'm using Resolume on a PC,but i assume it's similar in purpose to M8,i just can't figure out how to add a different video to each map. It's probably so simple,the penny just hasn't dropped yet. Thanks for your response.

[laughingcrows]

Awesome. Thanks for the info. :)

[DalecooperZ]

this stuff is the way of video art future... i love it!

[fiftynorth]

thanks for getting back. I take it you mean that when I take the picture I need to make sure I've 'cropped' the image size of the camera to the size of the projected screen......as near as possible?

[deepvisual]

@fiftynorth

no not at all.

use a focal length that has the same throw ratio/lens angle as the projector lens.

this technique only works if you use the same lens angle on both projector and camera.

[fiftynorth]

Hi, this is a revelation! I don't know much about lenses but the lense on my digital SLR is 18-55mm and I have an epson EB-X7 projector. Would these two work together or do I need to get a 28mm lense? Thanks

[deepvisual]

@fiftynorth

maybe. try keep the zoom in the relevant area, so the lens ratios are the same

[roskildahphreak]

I wish i could do stuff like that. Wish i had the imagination anymore.

When can we expect to see this applied to common concerts and festivals?

[deepvisual]

@roskildahphreak

there was a major mapping installation at glastonbury this year!

[roskildahphreak]

@deepvisual Nice!

[LMVP1]

Were do you take the picture at when you are using more then one projector to cover a building??

[deepvisual]

@LMVP1 from where the projector is.

Superb

hi mann, i only have a windows laptop, i would like to do this as a part of my collage project, is there any way i can do this using a Windows OS, what software is best for basic mapping ans layering, i have Arkous and i cant so it on that :S

please help as i am very interested in this

thanks

[deepvisual]

correct re masks.

transparent and black .psd or .png and oversize

the only way in m8 to use multiple masks is to use one 'mask' layer per item - its important that your masks dont overlap too much or they can crop another part of the image.

[DeeJayKTel]

and one more question.

Is there a way to mask just a layer...

so that could do the mapping thing based on multiple masks?

I had a look at the online modules and could not find one.

Is there something in the filters that can be used?

thanks

[DeeJayKTel]

also when I went to resize the mask using the Global Mask layer tool.....and had to size down my mask...it ended up revealing video over the outter edges....

Guess I should keep the original photo full frame to what the video frame will be and not crop it?

thanks

[DeeJayKTel]

When creating the mask in photoshop....what mask type should i be creating. Been confused with this before.

Basic what should I treat

A) the area that I want video to "punch thru"

B) the area that I want masked off or not to go thru.

the options that I think I should use are:

1) Black

2) White

3) Transparent

I created one with having the "punch thru" as Transparent....

and BG as black which seemed to be correct.

[tweekskratch]

Very cool thanks!

[Tezzathegreat]

Many thanks for your help, may be in contact again.

[deepvisual]

get yourself over to vjforums or vjcentral...

[Tezzathegreat]

Could you advise me on vj software for a beginner?

[deepvisual]

I guess you use your VJ software

[Tezzathegreat]

Hi, i was wondering how you put the image from photoshop into the projector if im already running vj sorfwre through the projector.

[wenzelmehnert]

Oooouuhhh... you spoil all the fun by giving away the how to :D

A magician never reveals his tricks...

but nice tutorial still...

[deepvisual]

Generosity is the greatest magic of all.

besides, this is kids stuff.

[wenzelmehnert]

:)

just saw some of your other videos... guess you are right about the kids stuff... I'm just getting into so I'm still amazed by it :D

[TommeeT]

Cheers for all the top tips mate! At the end is that just one layer of video on the Codanova or seperate elements on the different buttons & dials? So how would you do the latter please?

[deepvisual]

there are a few vids. each one positioned under the mask and scaled down so they dont overlap.

[tasgko]

hi deep visual!this is some very good advice but could you please answer the question of JaggedEdgeMedia about the position of the camera lence...thank you

[JaggedEdgeMedia]

Hi DeepVisual,

Does it matter that the camera is above the POV of the projector, or should I put the camera lens in the precise position of the proj lens? My only concern is that my throw distance is a lot smaller, about 1 meter. Maybe the perspective will be thrown off slightly at that distance?

[deepvisual]

parallax error is worse with wide angle lenses and short throws, but almost none existent with long throws.

so it will be a big help to get the camera as close to the projector lens as you can -

[soundcn]

Hey Deepvisual! I met some people that said they have worked concerts with you in Las Vegas, they were reps for the Hippotiser media server.

[deepvisual]

indeed. the hippo boys know how to party..

[deepvisual]

codanova VMX - the new novation controller is worth a look too.

[m4t3KK]

what is that kind of controller with the projectin on it? can´t find some usefull branding to identify the manufacturer. (vmx w?)

[vjsolly]

fantastic tips thanks.

[JaggedEdgeMedia]

thats amazing mate, thanks for the tips!

[MJpervshit]

just use the perspective transform effect in VDMX much faster and you don't need a camera.

[deepvisual]

yeah..... but no.

PT is only good for basic mapping.

[MJpervshit]

your example is basic

[deepvisual]

because??

I've accurately mapped 51 different images in one screen. If that's your idea of basic, then lets see some of your advanced mapping

[MJpervshit]

What I ment by basic is that these are basic shapes, squares and circles. Your method is also weak in that you are just removing bits of video with a mask, advanced projection mapping for me would be things like Pablo Valbuenas Augmented Sculpture, I was not trying to piss you off my good man, your technique is good i have also used it, drawing masks in photoshop over the real objects in fullscreen is also a good way of getting this effect. good luck to you sir have a good day.

[deepvisual]

well, its squares and circles because the codanova is made of squares and circles. The intention being to demo the procedure. Of course the masks can be very complex. you could always then take the mask into AFX and tailor individual clips to fit, but no point really.. anyway, I wasn't pissed, just confused.. thanks..

Excellent!!
