How to play time-lapse photography with mobile phone
Hyperlapse is a new independent product launched by the Instagram team. Based on ingenious algorithm design, you can easily follow the subject with iPhone, with the effect of time-lapse photography? It is a photography technology that takes images or videos at a low frame rate and then plays the pictures at a normal or faster rate. In this way, in a time-lapse photographic video, the process of slow change of objects or scenery is compressed in a short period of time, showing a strange and wonderful scene that is usually imperceptible to the naked eye.
In the past, it was necessary to maintain the stability of sports photography through an expensive camera stabilizer, and then use special camera equipment with a price of more than $6,543,800+5,000 to ensure the presentation effect of the picture. But now, all you need is your iPhone.
Hyperlapse's products are surprisingly simple, so that the recording button itself is the only UI design of the product. There is no other border decoration, and it is not deeply hidden, but it is unknown? Clever interaction.
Speed is Hyperlapse's only filter? A rapidly rotating rainbow ring; On the bridge? A steady stream? Traffic flow; Ordinary stratocumulus clouds also become unique in the flow; The building quickly moved the camera to the right, and the rigid reinforced floor had a beat and rhythm; Strangers hurried past each other and ran to each other? Crazy? Doing all kinds of exaggerated movements. The launch of the product tells us that speed has changed all the familiar and unfamiliar things around us.
The speed slider is a joystick, which is used to change your perception in Hyperlapse, and change the speed from 1X? 12X When the time comes, you will shake the rocker of the whole world like a creator? It can come slowly and poetically, or it can swish. Boom? Get up. Maybe you will understand now, why is Hyperlapse's Chinese name called? Hey, shoot? Let's go
Hyperlapse was originally inspired by a documentary.
Thomas Dimson is one of the ordinary employees of Instagram. He is processing Instagram data, trying to understand how people connect and spread content through services. But he is also an enthusiast who loves video works. His favorite movie is a documentary called The Mystery of Heaven and Earth. In his senior year, an architecture major introduced him to: You must see this movie, it will promote your mobility? . The documentary's creators have traveled to more than 150 regions in 24 countries on 5 continents, with contents ranging from starry sky to floating clouds, indigenous settlements, banks of the Ganges, sunrise and sunset. It records the changes of civilization and is full of changeable religious narratives. What shocked him most was that the whole movie had no narration and no plot, so it lingered in his mind.
According to Wired magazine, Thomas Dimson contacted Alex Karpenko in 20 13, when Carpenko had sold his startup Luma to Instagram. Luma designed a technology to enhance video stability for iPhone, which was quickly integrated into Instagram. But Dimson realized that this technology can also exert greater imagination, just like the lens in Heaven and Earth.
Karpenko has been pursuing the technical scheme of video anti-shake, because jitter will greatly reduce the visibility of mobile phone video itself. In the experiment, he also found that the technology in video editing software such as Final Cut does not apply to mobile phones. Due to the violent motion of the camera, it is necessary to analyze the film frame by frame in order to make the image segments consistent? Through the picture content of the image, the motion of the camera is inferred to compensate the deviation of the picture. This usually requires a movie studio to render all night with a computer, but it is ridiculous to do so on a mobile phone.
By chance, Carpenko saw Demo, a technology to prevent photo shake through gyroscope, which gave Carpenko great inspiration. He believes that on smart phones, energy-consuming algorithms should not be used to predict the motion of analog cameras; Instead, the motion itself is measured by the built-in sensor, and then the picture content is corrected.
Dimson quickly came over to Capencora and designed the prototype of the product together. The product they want to make is not just an anti-shake camera, but you can take it everywhere, and the final video effect is still very emotional. In fact, the picture you saw in Hyperlapse has been enlarged, and the filter will cut off the edge of the video so that you can't see the jitter.
The two of them uploaded the samples to the internal information exchange page. Kevin systrom, co-founder of Instagram, commented, Is this really cool? . This encourages them to sell their products to more people. In the company on June 20 14? Marathon. In the activity, they use it as a creative tool. In this activity, a variable-speed movable rod was added to the product.
Dimson shared the beta version of Hyperlapse among colleagues, which quickly detonated within the company. So much so that Gabe Madway, a spokesperson for Instagram, said with emotion: I am surprised that my colleagues did not reveal this wonderful idea. ?
Hyperlapse was finally launched as an independent product, not a new feature of Instagram. The company's CTOMike Krieger explained:? We don't want to do a special function and then hide it.
