We are promised a video in real time without friezes and jerks
 
Every time I launch Skype, Zoom or Hangouts, I'm looking forward to a fresh batch of jambs with video and sound. Technologies rarely disappoint me: croaking, background noises, loss of voice, video splitting into "squares", frozen frames and other joys of videoconferencing are haunted by video calls as I recall myself. Interest in many respects professional: in addition to programmable telephony for conventional phones, web pages and mobile applications, we at Voximplant ship developers video. I want Full HD, in real time, without friezes, in any browser and a conference person at 50. Interestingly...

Disney introduced her own hair animation system HairControl

Disney introduced her own hair animation system HairControlOne of the most difficult problems of modern 3D animation is still in such a seemingly simple thing as drawing hair. In fact, creating a hairstyle is one of the most difficult and time-consuming operations you can imagine. Animation and game studios have learned how to use real actors for the removal of their movements and giving realism to the actions of the characters. The same applies to the animal world when it comes to "bestial" animation films, even if the characters are made anthropomorphic (as, for example, in the "Zveropolis"). But if the animation of wool or short "half-box" haircuts ...

How we learned to connect Chinese cameras for 1000p to the cloud. Without registrars and SMS (and saved millions of dollars)

Hello!
 
Probably, it's not a secret for anyone that recently cloud-based video surveillance services are gaining popularity. And it's understandable why this happens, video is "heavy" content, for storage of which you need infrastructure and large volumes of disk storage. Using a local video surveillance system requires funds for operation and support, as in the case of an organization using hundreds of surveillance cameras, and in the case of an individual user with multiple cameras.

Nvidia has taught the neural network to slow the video

Nvidia has taught the neural network to slow the videoIn our life there can be many moments that need to be recorded on the camera in slow motion - the first steps of the child, the first trip to the sea, the trick of your favorite dog. Modern smartphone allows you to shoot at a rate of 240 frames per second or higher, but constantly in this mode you can not record - there is not enough memory and the battery will sit up quickly. Created by Nvidia, the neural network works with the footage already captured, turning them into slow motion.

One day from the life of the Eagle in a few seconds

One day from the life of the Eagle in a few secondsCurrently, on the Internet there are many sites where you can watch videos online from CCTV cameras, which are located in public places of certain cities. In particular, several such cameras are installed in the city of Orel. One of the cameras, which is located on one of the high-rise buildings per.

", Or how we realized the work with faststart-video for AndroidMost owners of smartphones, tablets and other gadgets daily consume a huge amount of digital information, including media: images, music and, of course, video. At the last stop in more detail. It is very important not to force users to wait for content, especially when millions of people use it daily. In the iFunny application we are working on, there is a lot of video content, and we thought that downloading the whole video is long, uninteresting and not scalable. And what if in the near future it will be necessary to download a video with a duration of not 30-60 seconds, but in 5-10 minutes? ...

DevConf: how VKontakte went to its platform for live broadcasts
 
In 201? we used a third-party solution. We embed his player on a site like youtube and it worked. It did not work perfectly, but at that time it suited us for the volume of broadcasts, which could be launched through it, as well as the quality and delays that it gave. But we quickly grew out of it.
