3 Basic Types of Video Projection Mapping
Вставка
- Опубліковано 3 лип 2018
- Video projection mapping is the basic foundation of video art. Projection mapping is the correction of an image for the surface it is projected on. This might be a simple keystone correction or a complex adaption for architecture using 3D-scans and specialised software.
That being said: It's not the art itself. Videomapping is just how you project your content. In this "sort of" tutorial I show You some types of mapping and how to do them.
This is more of a behind the scenes than a tutorial to 3D projection mapping.
Don't get stuck in technical mapping, instead go out there, create great content and amaze Your audience with a story!
If You like this projection mapping tutorial then maybe look at the rest of this channel. This channel is all about projections for stage, projections for theatre and projections for video installations.
And if Your area of activity are clubs and events then drop me a line. I will try to do more tutorials for VJs or people who like to use projections in different Ambiente.
And if You feel that my videos have helped You and You want to buy me a coffee, feel free to do so at paypal.me/philipp7pc

You are a God send, thank you much for sharing, ive been struggling alot with the virtual shadows.
Thanks for watching!
I've seen even big "mapping companies" struggle with it, so I thought it was worth mentioning.
This has been the most helpful video i have been able to find for projection mapping. Thank you so much!
love the light you used to map on your closeup
Really cool video thanks! Interested to know more about projection mapping
Haha mit Abstand bestes cinematic intro, das ich seit langem gesehen habe 😜 Da können sich Peter und Matti noch ordentlich ne Scheibe von abschneiden!
Watching a man talking with such passion and calm about a subject really gets you in. I'm doing a bit of research right now and so far I really like your video. Music is helping too. Subbed and take care!
Thanks - and thanks for watching!
beautiful work keep doing!! i love your work..
i love what you do
keep it up
This is exactly what I've been looking for.
beautiful work
really very knowledble tutorial sir. want to know more, will see your all tutorial and then will ask some questions. thank you so much.
Welcome to the channel !
Wow! Good job! 👍👍
Finally, a comprehensive crash course on mapping. Maybe part 2 will go a little further in depth on how the software works.
Thanks for watching. I will dedicate more and more vlogs to the main software packages for mapping and video servers. One handsOn to Pixera is out there already.
I’m so new to this. Literally like a baby… LOL. Thanks for throwing some light on the subject (pun intended)😅
You’ve earned yourself a subscriber, good sir!
wow!! so cool DIY ~~~
Gutes Video & die aufkommenden Probleme mit Abstand, Winkel, Brennweiten usw. gut aufgegriffen. Vielen dank
Danke!
Thank u for sharing really interresting!
My favourite tech plus ASMR channel in UA-cam
U r really master , u deserve the support for sharing such knowledge ✌🏻
Thank You, my Sir. It’s nice to know people from all over the world watch my humble vids.
philipp7pc I honestly interested of what ur doin! U got my support from Qatar ✌🏻😬, I’ll do my first mapping n video it to u soon
Great work.
this is a great ! I'm a young man Learning about projection mapping this is a great help for more knowledge :)
Thanks for watching! and a happy new 2021!
Der Moment wenn dir einer nen Floh ins Ohr setzt! Das scannen mit der Kinect macht mich neugierig! Sehr interessant! Daumen und Abo!
Herzlich willkommen!
Sehr interessant Philipp 👍
Nice one!!
Very helpful
Thanks a lot
Coole Sache, hab einiges gelernt 😌
wow it so cool.
Hello, really creative tutorial. I really like it. I am wondering if you have played with spherical projection? I am working on it. The situation is we only have one projector vertically under the peak of semi-spherical screen. And we want to project our footage onto the screen without much deformation. The audience will be seating in the sphere. But We don't know hot to calculate the original footage? Do you have any suggestions or recommendations? Thanks a lot.
Thanks for watching! It sounds tricky what You are planning. Keep me updated about the process. Sounds very interesting. I know that the university in Potsdam is experimenting with dome projections. And maybe the orb plugin by videocopilot allows such a distortion. But it feels like the real problem ist the creation of the footage - i would go mad trying to wrap my head around it. If You are using a 360 camera like the insta360 it might be an easier approach.
thanks a Lot
Great video. One question for you. at 2:25 you measured your "surface"(box) so you are able to create your footage. How did you convert the measurement in inches to pixels(200px X 600px)?
Hi, thanks for watching. For me there are two important things to find out: the pure relation (i.e. 1:3) and then the number of pixels I need to on one hand not exceede my render times too much but also not get blurry because I created content with too few pixel of resolution. In this case 600 pixels seemed the most pixels that I could fit into the projected area. You might want to be on the save side. So if an object's hight is covered by half the pixels in an HD projection that's 1080/2 pixels, have some optical headroom, and go for around 120% of that. so some 700 to 800 pixels. Every pixel more is a waste of time rendering.
But remember: If Your projection system requires "official" file formats, You might have to look up, how many pixels the specifications order. (Might be something odd like 1024 by 768 or so.
wow, I really didn't think people still did it this way. Props on doing the hard way, thats a lot of work, and you have to render it out fixed too! How do you even do this with multiple projectors?
;]
Well, it’s a mix of two things. One is that many venues still don’t own systems that are capable of real time 3D mapping.
And the other is the money. If You do this as a small theatre or on your own (which I think the majority of the viewers are) then owning after effects for creation might have eaten up the budget already. (The rest hopefully went into a potent projector.)
@@philipp7pc It just so much extra work though! Why not use MadMapper or Touchdesigner. There are lots of tools that work better for this task and are made specifically for projection mapping. Why teach everyone a harder + older way. If you are really interested in "3D" projection mapping. AE is the wrong way to get into it. In my opinion, (sorry if you're offended) seems like everyone else likes your tutorial tho!
I feel It's like teaching people to make a spreadsheet in MS Paint. Can you do it, sure, but just don't.
Anyone who is interested can check out this list of projection software. Notice that AE is not on the list.
projection-mapping.org/software/
(don't mean to be rude or anything. I just think you are misleading the sheep, some who may be interested in actually getting into projection mapping)
@@HarveyMoon Hey! Sorry, I should check the "held for revision" tab more often. Your comment was blocked due to the link. (Good listing by the way)
I absolutely agree that dedicated video servers or mapping software is the best way to map your content.
In the above video I mainly concentrated on the pure mathematical or physical aspect of mapping. AfterEffects was only used to simulate what most of the many many pieces of software out there do.
Using PandorasBox, Pixera, Hippo, D3 or even a complicated environment like touchdesigner is definitely the way to go. But first one has to understand the general concept of mapping.
I figured that taking the long way might explain this concept a bit better. But if You like, there are some vids on this channel where I look at software packages that do the trick and I plan to do more clips featuring those programs.
So no offence taken. ;]
Great video ! You UV mapped the 3D model of the concrete object using element3D , put texture on it and everything but how did you manage to orient the 3D object in After effects so as it fits perfectly after projection ?
Hey. Thanks for watching. I used a technique described here: ua-cam.com/video/_BvOrVEdfPQ/v-deo.html. But the orientation should be done by setting the x,y,z coordinates in Your 3D software
Hello, thank you for your videos, I'm starting to learn video projection by myself and they are very helpful! If you have the time and know the answer I have a few questions: To make a body mapping (I'm looking forward to make body art with projections) is there a specific software? Do you know the best way to do it? And for mapping buildings and objects to put videos and animation on it what is the best software as well? After effects or mapping software? (with these last one I find it hard to create animations and to insert existing videos). If you have any tips for theses questions I'll be glad to hear it! Thank you :) - I work as an editor and visual arts.
Hi! And thanks for watching! As bodies most times kind of move around they are a bit more complicated to map. There are ready made systems that capture the body, like pmd-art.de/en/ or - if its a smaller scale - you could dive into using a kinect and a program like touch designer.
On the back end as a media server I usually use mapping software like Pandoras Box, D3 or lately touch designer (if it needs to be "interactive").
mapping forever!
This has been very helpful, thank you so much. On 3:50 is that a projector behind you?, can you please recomend what project brand will be good for learning projection mapping.
Thanks for watching!
Yes, the small little thing is a Philips Piko projector with a laser led mix, In fact any projector is fine if You're starting out. But I would recommend a resolution of minimum 720p (it's just more fun to see less pixels) and some solid state lamp like laser or LED or a hybrid laser/led. Because knowing the prizes of classical lamps you will not turn it on and practice as much as you would if lamp hours don't matter.
@@philipp7pc I watched your other video "What video projector to buy?
" Very well explained! I appreciate your taking the time to answer my question. It has really helped, Thank you
Philip, I just wanted to build a projection mapping on Lord ideal with in 5meters, Would it be possible?
hey great video thanks. btw which program are you using for video programing ?
Mostly after effects - to create footage. It depends on the venue what server software they use.
hello Philip how can I make a cheap rear prjection panel with transparency to project geometrical animations, preferrably to be able to sue 3 to 4 layers for different projection points
Hi Philipp,
wie heißt diese Suchmaske für Tools in After effects? Das ist ja genial!
Ja, ist genial und auch noch gratis. Nennt sich FXconsole und kommt von Andrew Kramer von VC: www.videocopilot.net/blog/2018/05/fx-console-updated-to-v1-0-3/
philipp7pc cool! Danke dir!
This guy out here shooting with his camera on like 9000 kelvin
Hey Phillip! I really liked your video and I need your help as a beginner, I'm a video editor who always used adobe premiere but rarely after effects, I have to do visual art for a play and I don't know the basics of converting meter to pixels and the effect of the projector's distance from the stage. Can you give me pointers?
Hi, thanks for watching!
This one: ua-cam.com/video/_BvOrVEdfPQ/v-deo.html was too confusing I suppose?
really nice want to know in more details if any videos please share
please keep sending me more wanna learn more about this .
nice
nice tutorial
Hi brother i am from india
I am a part of a advertising company in saudi arabia , i want to know wich tools need for projection mapping ( projector....etc) and which company normal price and good quality
hello im having a hard time figuring out how to setup after effects with projector so it works as a video output thank you
Hi!
Thanks for watching.
With your projector connected and run as a separate display head over to Your ae preferences and under the video preview tab enable mercury transmit with the projector as your video device.
@@philipp7pc thank you very much and merry christmas!
cool

@@philipp7pc hahaha okay
Hello Philipp, what is the minimum spec video projector for a medium to big size room video mapping ?
That hugely depends on several factors (firstly: how big is medium size).
Lumens: they say five times the illumination of the general space. So if you have 100 lux on that wall you’ll need 500 Lux x m2 as light. (3x5m = 15m2, 15x500=7500 lumens for the projector.
And then You don’t want Your audience to see individual pixels. In this cast perhaps less then 1/4 inch. So 1000 Pixels wide minimum.
Now just adapt these thoughts to Your case ...
thank you for this tutorial, What is the name of the software you used in 2:23 minutes??
haneen ahmad thanks for watching! You’re referring to the portion of the tutorial where I’m using after effects. I wouldn’t recommend after effects to actually map your content. But it’s great to show the principle of the process.
@@philipp7pc Thanks, so what free projection mapping software do you recommend me to use?? I am creating a project for my university
Definitely have a look at HC Gilje’s vpt. hcgilje.wordpress.com/vpt/
What is the minimum lumen do you need to get the effect .. optimal.. with a room not fully black ? In your video it's day.. but you are quite near.. with laser projo perhaps.. Thanks
Hi! And thanks for watching! The brightness of the projector hugely depends on the size of the projected area and the ambient light. There is an old DIN that states that for good readability a projection should be 5 times as bright as the ambient light. So if You have around 300 lux on Your surface from the surrounding light You should ad a projection light of 1500 lux ... This number times the square meters of Your projected area is the Lumens (lux per square meter) that Your projector should have. In my case the projection was 2 square meters big which would have needed a 3000 Lumen projector. The projector I was using was far smaller (500) so I could only show bright high contrast lines.
Given you turn the lights down a lot s you end up with max 100 lux on Your surface, and the projected area (all the area that is covered by the projector) is let's say 4 meters high and 7 Meters wide (so it's 28 square meters) the projector should be 5 x 100lux x 28squaremeters = 14.000 Lumens.
At least I hope that's where we should end up with. My maths teacher never was too happy with me.
The images from the bigger mapping at the end of the clip are from a 38 by 14 meter skate park using 5 31K projectors. So ... a little bigger than that thing in the studio.
Thanks again for watching - and thanks for sharing and spreading that channel over all Your social media ;]

Hi ich lerne mich zur Zeit in das Thema hinein hättest du irgendwelche Videos wo du Projektione auf wände... mit Vpt auf Deutsch erklärst?
Von mir selbst gibt es (noch) keins. (Kommt auf die Liste.) Das Original vom Entwickler ist ... naja, ganz ohne Text: ua-cam.com/video/6tPGP0Ga8a8/v-deo.html aber im Prinzip recht hilfreich.
Ok wenn du mal ein eins mit der kincet und in vpt machen könntest wäre sehr sehr geil
Ein paar Grundlagen unter ua-cam.com/video/uFr5gq0gJB8/v-deo.html
Und momentan sitzen wir an einem Tutorial zu interaktiven Inhalten auf amorphen Formen.
Sorry for my english i am french
Could you please give more information/details about the virtual shadows part i didnt understand ????
I putt it on my list of future videos. You are rights, it's a tricky thing not everyone cares about.
@@philipp7pc thank you very much my friend
What is the 3d software you used along with after effects?
To clean up meshes and build surfaces I use meshlab. For more complex corrections on a model I use blender. And for physics simulation I use houdini (or blender if it’s simple physics)
Inside after effects I would recommend videocopilot‘s Element 3D.
Thanks for watching.
Hi.. Can you suggest me which type of projector will be good for projecting on car.
1. Short throw 2. Normal throw or 3 Ultra short throw
Also if you can if you can tell me why you suggest particular type of projector it will be very helpful!
Any projector brand you can suggest that will be appreciated as well!
Anyway I have learned so much from your tutorial that I made money by learning through it. You are a good mentor and helping hand. Thank you so much for your efforts and time.
Thanks for watching!
It's a difficult question You're asking. But regarding the nature of a car with any short throw projector You will soon get into tangential areas at the sides. So the further You are away, the more You can also cover the sides. It's pretty much the opposite of what you would want with a concave object (like the bowl) as long as you want to fill it. The easiest is to use an eye, get close, see how much You see of the edges. Go further away, see how much more of the sides You can see (i.e. map).
So it would be best to use narrower projectors from further away if you are not using many projectors and point them to every surface/side.
That is, if I got Your question right.
@@philipp7pc Yeah I kinda got it. I wanted to say that if I use long throw projector then because of distance car areas will be flatter compared to if I project from wide angle. Also I know how to map from one projector using after effects. But as I can see you are suggesting to project using multiple projectors on one car. How to do that?
Sushil Badgujar i would normally create the video for each projector separately and then play them back from something like qlab.
Regarding the lens keep in mind that the closer you are the more of an issue focus becomes.
@@philipp7pc ohh. then its easy. Let me try qlab once. So you assign the specific videos to specific projectors using qlab only? or it needs to be set through computer.
And also suppose I want to create one effect going from start of car till end. Where it has to use two projector to cover entire area. Then it will be projected by more than one projector, how do you sync that effect..?
Hi! If I was mapping for example a whole skate park, could I use a premade model of the skate park I found on sketchup architecture application?
Hi! Thanks for watching.
I appreciate the question as it kind of hits the nerve of a very conflict rich project.
You could use the model if it was exactly the same as the original. If it isn't you shouldn't. Instead you could try to photoscan the park.
Who's asking You to map a skate park? This sounds awfully familiar.
@@philipp7pc Hi there thank you!
Do you recommend any brands for a larger project?
@@emilywisniewski2982 Brands in terms of projectors?
@@philipp7pc yes! Is there a good one for projecting on a large curved space?
Can you explain about undistorted projection on a random surface?
I think You will have to explain a little further. Like projecting straight onto things at many random angles? I see this happening pretty often in theatre.
Sure thing. That reminds me that I should link to my Twitter more regularly. Follow me on Twitter @philipp7pc
Suppose i project a cube photo onto a cylindrical pillar. So at the center of that pillar cube looks fine but if i move it to left or right of pillar then it will definitely change it's shape. So how to solve this so that it would look like it's floating in front of that pillar?
That’s tricky. You can try to make it look straight, but the trick will only be good from one point of view. As soon as You move Your head, You’ll See that is an illusion.
But I put this on my list. It seems to me as there is a need for a more in depth explanation.
Hi if I want to learn projection mapping on cakes which is the best software and projector I can buy and where can I learn I am from india
Hi! Well, I love cooking, but Cake mapping isn't my field of expertise so much. However through YT I came over a dedicated channel on cake mapping ua-cam.com/channels/yP40zKjYCECMkd3IKpyUSw.html
They also have a corner on their site lumabakery.com where they consult on software to use.
But if You wanted to generally learn how to map on cylinder forms it should be pretty easy depending on the software You are using. On a mac I would always first go using motion. It's cheap and versatile.

Thanks Sir
this is Day 1 of me learning projection mapping.
Welcome to the channel!
Oh.. and about your ratio.. I open a picture and resize it with the ratio found ..?
The ratio depends on the ratio in Your real life object. Many time I see people explaining mapping using a 16:9 image and then they squeeze it on a square plate. That's not a nice thing to look at.
Measure the ratio of Your object and then create footage that has this ratio (think of it as of wall paper). So if Your object is 1m wider and 4m tall the footage You create (and later projection map) should also be at this 1:4 ratio, but using enough resolution to not suffer when projecting. So as a rule of thumb the hight pr width of Your projectors resolution should determine the longest side of Your footage. I our example if You have a full HD projector (1080 pixels high) Your footage should be (according to the object) 1080 pixels high and ... well a 1/4 of this wide...270pixels ? (If it feels too few pixels give it some more as a kind of headroom, but mostly that works fine).
There are many projection mapping software you can buy - can you recommend one - Looking to map a building?
What's Your budget. There's a wide range. From the free vpt6 to servers like stumpf or coolux for tens of thousends
I was looking at Madmapper and HeavyM so around the $1000 mark or less. Unfortunately Madmapper doesn't have any manuals yet and I found HeavyD poor on customer service so probably wouldn't use them. I am going to try out a company called Lightform, but any suggestions would be good.
I Gevatter watched people use those two. But I’m still waiting on both to send me a license for review. ;]
I have some questions if you don't mind helping me out please! So I want to do a small prank on my friend and I want to create an illusion or hologram in her house is there some way this can be created in home and no evidence for her to see?
Thanks for watching! Well, first I would highly recommend ua-cam.com/video/4wVNzwr77NY/v-deo.html as a rough tut.Than with all pranks: Take care nobody gets hurt physically or mentally. And then: If You have (legally obtained) access to the home try to find a space like a cupboard or closet to hide the projector on top and turn on some music to hide the sound of the projector. And keep looking for curtains and other semi transparent materials to use as a projection surface. And the most important tip: Put a camera up to post the result and reactions to the internet. ;] (All compliant with local laws of course.)
Great cutting skilss though
Thank You!
How do you project full screen at the same time that you are working with after effects??
It’s the Mercury preview or in older versions the preview. You will have to set the comp size to the exact resolution of Your projector.
@@philipp7pc I cant find Mercury for Windows 10, I can only find it for Windows 7. Do you know what can I do??
In the preferences there should be a preview tab. You should find Your projector there as an option.

Do You mean the small one? That’s a Philips PicoPix. The large one is a Panasonic RZ31K
No for thw big screen
The big mapping at the end? Those are 5 RZ31Ks.
How many lumens and how many projectors? Can u guide me about the distance etc?
khurramdotcom1 It’s 5 projectors by Panasonic 30.000 lumens each covering all over 22x40m of concrete with a distance of something like 20m. The projector prize was something around 130.000€ each.

Hello sir, I am emerging in led wall Industry.I need to know about how to make 3d mapping videos like which software to be used for that.
Thanks in advance
Thanks for watching.
There are basically two areas - creating the content in some compositing or editing software like After Effects, Apple Motion ... and then the media servers that one would use to present the contend. Both can achieve a mapping of some kind. But media servers like Pixera, Pandora’s Box or D3 are the better (quicker) choice.
hey, thank you! I'm afraid the only problem in video art is the price of the machines. Anyway, this is life in capitalism

Actually the sad truth of capitalism is that the machines become cheaper and cheaper. (Don’t ask on who’s cost. But mapping is becoming a game for the masses.)
