“Fake video work of the smartphone application with the background around” or “How to save on the DIY stabilization system” or “Is it possible to write this down with a thread of software right in the smart?”

Preface.

Looking through the comments on the topic “Shooting video from the iPhone screen in motion - DIY stabilization system for DSLR or HD camcorder” I came across a comment that was addressed to me. Actually, I realized that the question is addressed to me in the same way as all the Habrolists do - I see a question, so they ask me. I thought to answer with a simple comment ... But then I realized that I needed a detailed answer.

And so, how to make a fake video of the work of a smartphone application and even so that you can see what is happening around?
I immediately ran into the corridor ...
... and recorded this video:


Already something like the video from the original article, is not it?

')
Not enough smartphone in the middle. I shot a video on my Galaxy Nexus, but since we want to attract investors to our application, we will use the iPhone. I looked for frames from iPhones in the network , but, unfortunately, almost all of them were with an ugly glare in the middle. In our fake video this glare would be terribly annoying. In general, any glare needs to be animated, for a realistic video, but we don’t have time for this: investors who want to give us their money will knock on the door from minute to minute because of our unrealistically cool video about a smartphone app. Therefore, take this frame:



It is less pronounced glare, but the fact that they do not move is not noticeable, unless you specifically focus on this. If anything, then we will tell investors that our application can still freeze the glare on the smartphone. (Then we remove this feature as unclaimed)

To edit this great video, I will use Adobe After Effects. Just because if you write in the estimate that the work was done in it, it looks cooler. And so, the same can be done in any video editing program that has a blur filter and layers. Tobish almost any. Hypothetically, this can even be done in any, not yet written, smartphone application, which was originally asked by the user fdv . But I never found normal video editors on Google Play. If anyone knows, tell me, I will be glad to make a video about iPhone right on my Galaxy Nexus.

Step number one - the imposition of a frame phone.

We will impose a frame in the center of our video, so that it barely touches the top and bottom edges of the screen:


Of course, since we do not use any DIY devices (and therefore are not connected with reality), then we can make the phone levitate before our eyes:

... but it will look stupid and not realistic ... So we will do it.

Step number two - shoving a backup video into the phone.

As you can see, the original video was filmed by a Galaxy Nexus, tilted about 90 degrees to the side. And our iPhone is located vertically. So we need to trim the excess from our second video on the sides, and reduce the remaining stump a bit so that it fits into the frame of the iPhone. Also, the video should be slightly darkened; As you can see from the happybyte movie , Gorilla Glass transmits quite a bit of light. It turns out something like this:

Step number three - blur the background.

Not enough realism? Add blur!
We impose a blur effect on our background, and voila:

It can already be considered a complete result. Only a couple of trifles are missing ...

Step number four (optional) - add special effects.

Since our iPhone is flying in the air, thanks to a powerful magnetic field, it should at least sway from side to side. Something like this:


But we know how it happens with batteries ... So our hyper-magnetic installation did not work long.

Glue the iPhone in place of blue tape. It turned out quite similar to the video that we tried to imitate. Only one thing is missing ...

Step five is the interface overlay.

We did make a video about the program ... And the program probably should have an interface.
And what, strictly speaking, will our program do?

In general, what our program does, in my opinion, is already clear from the interface.

Summing up the results.

Here you go. With such a video, it is not a shame to appear in the light and take money from investors. Of course, it would be worthwhile to make the form a little longer, first make a beautiful screensaver, and somewhere in the middle show how a pretty girl uses our application ... But we will do it next time. In the meantime, I will go and see what investors are all doing at the door do not ring; maybe someone's door bell hung?

PS This is just a habro-topic-answer to habro-koment-question. I hope that soon any habro-question will be followed not by habro-ignore, but habro-answer! After all, if each of us, to the observed habro-question, will give not just a detailed habro-answer, but a whole habro-topic, then the habro-community will be even more rapidly habro-grow!

UPD.
Here, many were surprised that a cheap popular video came out of the popular print topic, so I add a more expected result:

Although, of course, for better glare, it was worth recording a separate file with the video behind the shooter. It would be perfect if the phones could shoot simultaneously on both cameras ... Oh, dreams, dreams!
