Facebook, Intel, Microsoft, all these giant tech companies, they throw billions of dollars into the invention of a brand new virtual experience. Having a 3D television at home or wearing 3D glasses in the cinema is way out of date. Perhaps it is no longer being used unless you are pursuing the lifestyle of ultimate simplicity. However, people still wear glasses, like Google Glasses, which gives people the experience of augmented reality Or wearing a VR headset to experience the world with a whole new level. Of all these brilliant experiences, of all these brilliant inventions, they all link to one thing: volumetric video. According to AP News on March 5th, 2020, the global volumetric video market is estimated to grow from $1.4 billion in year 2020 to $5.8 billion in year 2025. 32.8% growth in 5 years. Today we will look at volumetric video, including the process, the market usage of this technology, and also the problems. Volumetric video is a new filming technology that can be used to record and film 3D volumes with exact dimensions, so-called holographic video. According to New York Times on September 5th, 2018. This is a new video format with new production process. Rather than filming the subjects from, from just a few perspectives, it is captured from all angles. In order to get this work, the performing stage has to be surrounded by multi-synchronized cameras. It can be from 30 to 100 or even more based on the scale of the stage. The production team then will surround all these cameras in every angle. The stage has to be surrounded by green screen as well, so that after the filming, the production team can cut it out and make it into a 3D dimensional volume without any backgrounds. After all this process, the software engineers will transfer all these files into a way to suit our personal devices. One of the examples is USA Today. People can download their app and watch volumetric video through their cell phones. Also, this technology can be livestreamed as well. Based on CNBC on June 26th, 2018, Intel is cooperating with a lot of producers to make their activities and programs into live actions. Furthermore, on November 22nd, 2019, Forbes has explained that people can customize their watching experience by changing the size of the performers, And place them into whatever backgrounds they like. So far, I've covered the mechanism of volumetric video. I will now talk about the market usage. First, film industry. Volumetric film brings people inside the scene, zoom in and out as if they are experiencing the ongoing actions. One of the examples of this movie is Fastish, created by Aaron Bravery. This film touched viewers' hearts by bringing them walking into someone's memory. It seems legitimate to call them walkable movies since people can walk inside the movies. Fun facts: the first movie with sound is called talkies. Now we have walkies because people can walk inside the movies. Second, business industry. AVEVE, a volumetric content creation platform, has created an easier way for the users to access and create their own 3D content. According to Steam, a video game distribution platform, as long as you have an EFIF cameras app, Windows 10 camera, and 2 Kinect V2 cameras, you can make your own volumetric video. People now can livestream themselves online whenever they want, and the best part is you don't need any multiple cameras, or green screens. Lastly, medical industry. News 9, a CBS-affiliated television station, on March 3rd, 2020, explained that the advance in medical imaging technology for more accurate diagnosis is expected to offer avenues for the market from year 2019 to year 2025. Also, the use of volumetric display in medical imaging applications to create real-time visualizations has been widely accepted across the medical industry. As of now, I've covered the usage of this technology. Now let's talk about the problem. First, hardware and software. The way the volumetric video is made takes insane amount of storage to store all the data, which leads to buying bigger equipments. Also, this is a very sophisticated technology which requires high-quality equipments like cameras, processors, sensors. Also, AP News on March 5th, 2020 explained that the requirement of complex software solution for image processing is a must and will— it will lead to a high production cost. The next problem, workforce challenge. There are many people and processes involved in order to complete volumetric video. According to New York Times on September 5th, 2018, it requires more collaborations between the performers and the production teams. Sometimes because the stage is not big enough, the producers have to design walk patterns for the performers so that when they are filming it, it looks natural. According to AP News on March 5th, 2020, it suggested not to take volumetric video under the sunlight because when the sunlight is present, it will affect— it will decrease the quality of volumetric video. Today we've talked about the mechanism of volumetric video, also the 3 industries applied to this technology, and The 2 major problems that need to be solved. The difference between humans and animals is that we are always looking for an update, and we are always looking for the answers to solve the problems. Recently, the coronavirus has dramatically changed our ways of behavior and our habits. It just seems that volumetric video just appeared at the right time.
