- This tutorial covers the 3d video projection mapping features of Qlab 4. We will look inside the Video Surface Editor and talk about the difference between surfaces and screens. We will also experiment with features like warping, masks, splits and constraints as well as setting up multiple projectors as screens.

01:00 Video Surface Editor
01:45 Screens & Surfaces
04:24 Warping (Keystoning/Corner Pinning)
05:18 Masks
07:30 Constraints
08:25 Splits
09:33 Basic Cue Sequence
10:45 Multiple Projectors

@Riley Makai Great! 👍
Holy Crap! this video is a life saver! I have a show opening in a week, and I JUST got my projector this evening, and was in a panic about learning how to get it set up with Qlab to do a projection, I was slightly familiar with screens and surfaces from other tutorials, but this video absolutely locked it in for me, Now when I get to the venue tomorrow I am positive that I'll be able to get it up and running properly! and am super excited about the future possibilities of projection in a theatrical environment, Thank you!
AWESOME!
I might have to fall in for a theater show with sound and video. Sound is no problem, now with this tutorial (SUPER WELL MADE), I can go assured the beamers won't be a hassle to set ^^
AWESOME 🤩
Clear, concise, and to the point. Very good tutorial.
Thank you 😊 Hope it helped you

You're very welcome!
Really helpful, and great information
Glad you found it helpful 🙂
Very good; thank you.
No problem! 👍
I am your fan and like you with all signs of respect as you are my Teacher. I am enthusiast of video mapping so mostly videos I download. Kindly teach me in easy way please
Are you having trouble following the tutorial?
@@LumaBox I will be remain beholden to eternity if you very kindly prepare a video for biginner with brief how to place projector, how to connect laptop to projector, how the job/work for video mapping on building is started....???
@@Grandkidsmovies I know you've seen my house mapping 5-part series. That's the most 'beginner' I can get. I've also sent you the link elsewhere to videos about how to connect the projector
such a great tutorial! is it possible to rotate a screen in the video editor to a custom rotation (45 degrees for instance) or only on 90 degree rotations. I have a floor I'm trying to map to with a complex curved shape and I need to angle my projector to make the shot. Could I map that? Thanks!
Could you do it by keystoning the corner points?
@@LumaBox not sure! Thats what I was wondering but I'll try!
Seems so simple! Could you, with one projector that has a video signal with different inside screens be able to move those video screens to different 'boxes'? and simulate 4 differnt projectors (even if the resolution is not that great)? Thanks!
Hi. Not 100% sure what you mean, but this tutorial might address some of the thoughts you're having ua-cam.com/video/1tx_zXyjUjk/v-deo.html. In it, I try to break down the video content output from one projector into smaller sections to be mapped individually (and talk about the challenges of doing this in Qlab)
@@LumaBox Sorry, wasn't sure how was the best way to explain it but you solve the challenge in the first 2 min of your video link. That was actually what I was thinking. I think It is a job for Mapmapper. Thanks so much!
@@Charlie-tl4dv Great that the other tutorial could help! 👍
Hi there silly question. What’s the best way of using two different projectors from two different vantage points on to one surface (as the projectors on there own are not bright enough)?
I can probably guess the first response “don’t” but I could do with some tips.
Not a silly question at all. People do this. Each projector is set up as its own surface and then you would adjust the corner pinning so they sit on top of one another.
what video projector you think is suitable for a very big theater ?
My experience is with home cinema consumer projectors, so I'm not in a good position to give any advice on that. You'd need to be looking at using multiple extremely bright (i.e. 15,000+ lumens) projectors to cover the whole space. This type of thing www.epson.co.uk/products/projectors/installation/eb-l1755u
Hello, Your Projection Mapping tutorials have been so helpful, thank you so much. My question is, which mapper software do you prefer for playing back multiple videos simultaneously either using two or more projectors or layering video content? Thank you for your time.
I'm not much of a programmer so I do as much of the sequencing in video editing software and then bring a final video file into the mapping software. So far, I like MadMapper the best for working with multiple projectors.
@@LumaBox Thank you for your quick reply. I am the same. Not a programmer at all but I do know my way around video editing. Can Mad Mapper playback 2 or 3 different videos, starting simultaneously? I am hoping I can have one video playing on my main projector and a different video playing in sync on a second projector. Thank you.
@@hollowstudios2015 Yes it can, using scenes and cues. I have a video ua-cam.com/video/rXennwOHXXQ/v-deo.html
@@LumaBox Perfect, Thanks again so much
Is it posible to set video targets not being videos loaded on the laptop, but from somekind of Camera ? If so, is it posible to set several cameras ? Something like CCTV cameras set... Dunno if using some extra hardware ( the DVR they include ) or being wifi cameras. Or using some other sofware like OBS to control these camera then link it to the Qlab.
This might be a good place to start your research qlab.app/docs/v4/video/camera-cues/
Hi its amazing, cud u kindly as to assist me in projecting on a wedding gown. Thank u
That's not something I've ever done and would have to think about how I'd go about it. It's not as simple as mapping some cardboard! 😁
How are you connecting the second projector?
Do you have another display output on your laptop?
@@LumaBox I only have the two USB C ports on the Mac. So, I have to use one of them for power. I have an adaptor that gets me an HDMI port.
I've ran into na issue where nearly none of the buttons in surface settings work. I just downloaded the newest version.
That's weird. Can you roll back to an older version? Maybe email Qlab support? They're pretty good
How do you patch 3 projector to one laptop ? I only have 2 hdmi out on my laptop…
You need to use some hardware to split a single display into more than one - usually known as a "display splitter". Look into something like a DualHead2Go or less pricey alternative.
I am using a cheap 720p projector just to practice with, I am a complete beginner so I'm not sure if it's my own fault or the projectors but when I keystoned to the lightswitch on my wall there is still a faint coverage of light on the remaining surface that isn't being displayed on as a screen, is this fixable or is this because it is a cheap projector? Thank you.
This is very common and it might be partially because your projector is cheap, but even good projectors have it to some extent
@@LumaBox is there a way to make it less noticeable at all? As it is quite distracting
Usually I would move the thing I'm projecting on away from the wall so that there's nothing for the unwanted light to fall on to. Also you can light the back surface independently (spotlights etc) which overwhelms light spill from the projector. I appreciate this won't work with your light switch example. Also. make sure that you haven't overdone the brightness settings on your projector because that will also brighten the black level and cause this problem.
@@LumaBox amazing, thank you!
Software price?
Don't know. Check here qlab.app
No
No?
@@LumaBox sorry typo! Loved the video! Very helpful!! Keep up the pro work. AV gains
@@elliotslater5007 Ha ha. "No" had me intrigued 😁
@@LumaBox Hahahaha, i don’t even remember doing it
