Information technology's always heady to think about that adjacent big thing around the corner, which tin transform the mode that we live – and specially how nosotros communicate and deliver presentations.
Although whatlooks similar hologram video engineering has been used in high-profile performances in the past, such as Tupac'due south for a few years agone, I'1000 personally waiting for consumer holograms to get widely available.
While we're even so some time away from widespread 3D holograms, one thing that's sort of shut to a hologram video – and very popular right now – is this 3D hologram video pyramid. It consists of a video playing on a flat screen (I personally just flipped my laptop screen down), with the upside-down pyramid sitting on elevation and reflecting the animation. You can go some pretty cool looking furnishings, as yous can meet hither:
I absolutely dear this issue and could stare at it for hours. However, I don't like to make tutorials that "reinvent the wheel" and evidence something that's already been shown (in that location are sooo many out there on how to make the pyramid).
And then my focus for this tutorial is how to do the pyramid consequence withyour own video – and for extra coolness, one with your face up talking (what I telephone call the "hologram selfie"). I'll too testify how to do it with all types of videos, including ones you can easily become on YouTube. Check out what it looks like below.
To practice this fob y'all'll need the post-obit
What you lot need to make a hologram
Horizontal screen
First, you will need a screen that you lot can lay flat on your table. This can be a phone, a tablet, or a reckoner screen (which is what I used) – or some people have even flipped their TVs on the back to go some pretty giant projections. Of grade, the larger the screen, the bigger the effect, so I would recommend going as large as you can.
Transparent pyramid
Adjacent, you'll demand a transparent pyramid. At that place are tons of tutorials on YouTube for how to make this yourself, super inexpensive, out of a CD case and some tape, such every bit this one. Or if you're lazy like me, you can become it Amazon, such as the ane I got hither (combo pack for cell phone and table). Merely brand certain you go (or brand) it in the size that fits the screen you'll exist using. This will sit on top of your screen (more on that later).
Hologram video
Finally, yous'll need a video to project. You can detect a lot of these already made on YouTube, like the ones I showed in the instance to a higher place. Pretty much all of these videos accept 4 panels, which you tin see from all four sides of the pyramid. These are great for getting started with this trick and amazing your audiences correct away. To spice it up more than past calculation your confront, however, check out how to do it beneath.
A nighttime turtleneck (preferably blackness)
Preferably black. You lot could also get away with having a night shirt and a dark scarf. The most important thing is that your neck is dark so that you don't run across information technology.
A dark sail or background (preferably black)
You can hang the sheet backside you or you lot tin can fifty-fifty sit nether information technology, which is what I did since I didn't feel like hanging it.
For the lighting, you have to get a light source either pointing towards your confront or away from your face for a more natural wait (it will reflect on your face more than softly). Play around with the lite until yous similar information technology. You definitely don't want to have that scary flashlight face going on – unless of class information technology's Halloween, which could actually be very plumbing equipment.
Creating the hologram
Then go ahead and get filming. I personally simply utilize my phone to picture, so you don't really demand very fancy equipment.
One time y'all're washed filming, insert the video into PowerPoint (or a video editor), and you should take something like this. Not perfectly blackness, only very close and we can definitely work with it.
In one case we accept our video inserted, the first thing we demand to do is simply crop around the face up then that we don't have any of that extra video space to work with. So let's select the face video and then get to Format and so Crop.
Then merely crop around the face. Brand it as tight as possible without cutting into the face up.
Now what this besides does is information technology shows the states the border of the video, which is what we're going to have to blend in with the blackness of the groundwork. So we practice this by changing the brightness and contrast settings.
To exercise this, get to Format and then Corrections. Then curlicue all the manner down to video corrections options using the arrow on the bottom of the carte du jour.
We then play effectually with the brightness and contrast until the video groundwork around the face up turns completely black. We can fifty-fifty zoom in here so that we can see meliorate.
For brightness, I'll lower it down to -5%, percent, for case. So, permit's brand the contrast near 19 or 20%. Of course, this is all going to vary for your video, so simply play around with these settings until y'all find something that works for you.
Let's now deselect the video (by clicking anywhere else) – and looks like we have our video edges perfectly blended with the background, which is cracking.
Let's zoom out, then nosotros'll brand four different copies of the video so you tin can see them on ea
ch side of the pyramid. To do this, nosotros will start need a guide – so we go to Insert and Shapes, and and then under Equations Shapes, click on the multiple sign or the 10 here.
Go ahead and draw that in nice and big. Allow's put it in the middle of the slide and just make certain that it'southward square. Then we'll just need to even this out. Let'southward make information technology 10 x x on the size settings.
Now we know that this is perfectly square. Adjacent we need to make information technology a little bit skinnier by taking the xanthous dot that'due south on the Ten, and adjusting it so it becomes much skinnier.
And so finally, we put it in the center of the screen past going to Align and and then Centre. Going to Marshal again, and choosing Middle. The Ten should be in the eye of the slide now, and the space is divided into four separate panels that we can work with.
Your final result should await like the below:
At present, merely transport the X to the back past right clicking on it and choosing Send to Back. We can then place this video in the first panel. When you're placing the video, make sure you accept the office that volition exist facing the bottom pointing to the middle of the X (in my case, my mentum).
Information technology'south OK if the edges of the video are touching the X, as we're actually going to delete the 10 very soon anyway.
Next, nosotros're going to brand three dissimilar copies of the video (striking CTRL + D 3 times with the video selected) and place them and so they're all facing with the chin inward. Use the rotation adjuster to rotate them – or you can likewise use the rotation settings to make this exact. Here'south what the result looks similar – doesn't have to be perfect, but the X lets you lot go it shut enough.
Now that we've used the X to line everything up, we can get ahead and delete it.
Next, we need to sync up all of the videos so that they tin start at the aforementioned fourth dimension. To do this, we select all the videos past clicking on all of them in the Animation Pane on the right while holding downwardly the SHIFT key.
We and then take out all of the triggers past clicking on the selected videos on the Animation Pane, then dragging upwards (moving your cursor upward slightly) and releasing. The triggers are now removed.
Brand all the videos Get-go With Previous (or Start on Click) in the Elapsing and then Play instead of Pause (which was the default).
You lot are basically done – very nice! Y'all're ready to enjoy equally is, if yous like. However, I propose yous keep reading for some additional advanced tips to add fifty-fifty more spice.
Pro Tip #ane: Adding animations
First, consider whether you want your face up to have an Entrance issue. For example, for my introduction video, I had the confront come up in with a Zoom entrance consequence. Put whatever entrance furnishings (or emphasis or leave furnishings) you like on all the videos, by selecting them, then going to Add Animation and adding what yous want.
Here is what my blitheness pane looked like later on I added the Zoom archway. Detect how the showtime video has a start After Previous effect, and the others take a start With Previous effect.
Pro Tip #two: Improving sound and video playback
If your videos have sound, mute all of them except one – otherwise, information technology will sound similar a chorus of voices, since PowerPoint tin can't handle syncing all 4 videos at once.
To meliorate the video playback (i.e., making sure the videos play together), I suggest exporting the set of four videos to a new video – and so reinserting it dorsum into PowerPoint. This will ensure everything is synced properly. You can do this past going upwards to File, then Consign, so Create a video. After this, find the file and drag it back into PowerPoint.
Pro Tip #3: Maximizing video size
Hither's a tip that I oasis't heard anybody talk well-nigh yet in any of the tutorials I've seen – maximize the size of your video inside the pyramid by using only one video instead of iv.
The four-panel video is slap-up if yous're really going to be using this with an audience that will be looking at information technology from all sides.
However, in a state of affairs in which in that location's simply 1 side that's going to be seen, I personally like to maximize the size of the video and so that the audience can see the largest possible prototype. That is what I did for the intro to this video.
What I did there is but made the head a bit larger. Same process – yous just don't need the X. Keep increasing the size and testing it with your screen to brand sure the head isn't too large for the pyramid. Mine ended upward beingness the size below – so a flake larger than information technology was in the four-console video.
Pro Tip #4: Making your face colorful
If you want to wait actually creepy or like an alien or witch, for example, you can actually change the colour of your confront to be a fiddling scrap more than interesting. To do that, we select
the confront and then we become to Format, then Color, and if I want to make myself dark-green, I click on the green and black option here.
Looks expert already, just now I have to readjust the effulgence of dissimilarity settings to make the video background black. Making it green messed up our settings from final time. Let me just exercise less brightness (-nine%) and more contrast (34%), so the confront looks something like the below. Again, the key here is to make certain the black part of the video matches the blackness of the slide.
Perfect – a scrap more than interesting than just my regular face (maybe I should accept used this for the intro video, but I didn't want to scare anyone abroad!).
Final hologram video steps
At present that y'all're done with the hologram video (in whatever way you lot decided to make it), you tin can now add together the pyramid on top and projection. Make sure you screen is horizontal (figurer screen, tablet, phone, TV, etc.) and then place your pyramid on top of it.
If you accept a 4-panel video, put the pyramid correct in the middle (where the heart of the Ten used to exist). If you have a one-console video, put the pyramid correct underneath information technology (nether the chin, in my case) – exam information technology out and adjust as needed to make certain it's in the correct place. You lot tin besides change the click settings to brand it outset on click or With Previous similar what I showed earlier.
Dandy, that's information technology! Go out and attempt this. In addition to the 3D "hologram selfie" play a joke on, you can as well do this with any other video, picture or even text as well. You can besides use any pre-made videos on YouTube – just search for "hologram pyramid video."
Hologram usage tips
You lot may be wondering – this is super cool, but how could I actually use it in presentations?
There are many ways.
First, brand certain you have a computer or tablet available that can be used every bit a horizontal projector. This is the most practical projector for a pocket-sized-calibration classroom-blazon presentation.
Allow'south say y'all're teaching a class on birds or body of water creatures of some kind, for case, you lot could play one of the sea creature videos (similar the popular jellyfish one y'all can get on YouTube) at a primal moment in your presentation. Yous tin even walk around with it through the audition so that they can see it better. Only make sure to concur it in a higher place their center level for best results.
As another example, perhaps yous have a station at a poster session or science fair. You could have some version of this fox playing – maybe a product demo, a "hologram selfie" of the CEO talking about your company – or even a static photograph or logo to concenter people to your station.
Being spicy is all about standing out from others – and this issue should be cool and different plenty to exercise so. I hope this has requite yous some new ideas and inspiration.
Shoot me a note if you can think of other absurd uses for this trick or whatever other emerging presentation technology that you remember might be worth featuring in a future tutorial. I'd honey to hear your thoughts.
