Watch the VR special edition of "Shoot ANIMA! / ANIMA!"The unprecedented high -resolution video of 8K has a clear outline of the person, and it was so amazing that you could check the expression of the unexpected performer.
I heard that the resolution of 8k is 8K at the SKIP City International D Cinema Film Festival in Kawaguchi City, Saitama Prefecture on July 15-23, and the video work immediately.I went to watch.What I experienced this time is a short video work of about 5 minutes on the theme of contemporary dance, which decorates the opening screening of the film festival.
"Shoot Anima!" In that Kaho, who had not been able to find the dance he really wanted to express, approaches the contemporary dance and drum sessions for studying abroad support.Directed by Takahiro Horie, Ayaka Hattori and others appeared.

At the film festival, there is also a VR corner, so I was able to watch some free of charge, from this 8K VR work to be easy to watch with Gearvr.
The 8K VR work was played and viewed on a PC for mouse computer creators and engineers "DAIV-DGZ510S10S1-SH2" and HTC's VR head mounted display (hereinafter VRHMD) "VIVE".
At the venue, "DAIV-DGZ510S1-SH2" and "DAIV-DGX700H4", which adopted the higher-performance Intel X99 chipset, were placed.

If you know VRHMD, the resolution of VIVE does not reach 2160 x 1200 dots, so even if you watch a 8K video, many people think that the appearance is the same as the previous video. right.
VIVE was attached to "Vive Deluxe Audio Strap", considering the ease of installation at the event.
However, VR videos require 360 degrees, including not only the front but also the up, down, left and right back.Therefore, the video that is actually visible is a part of the video data that depends on the VRHMD viewing angle.It is said that the visible range is about HD image quality even for 4K videos.
Therefore, in order to see more clear images in VR, it is necessary to increase the resolution, and both video and VRHMD are required to have high resolution.Of course, the data becomes heavier each time the image becomes high, so the PC for regeneration requires the appropriate performance.VR processing is heavy, but video playback is lighter because the VR video currently widespread is a resolution that matches the current practicality.
Shoot Anima, which was exhibited at the film festival this time!The 8K VR work was played with Alpha Cord's own software "VRIDER", which worked on the production of videos.Therefore, it is not a necessary PC specifications in VR video playback, so it is good to consider it as a reference.
In fact, when I watched 8K videos in Vive in the above environment, I was able to watch it without any stiffness, despite the high -definition and smooth image quality than any video I saw so far.The mouse computer had a higher performance PC than the "DAIV-DGZ510S10S1 SH2" in case of emergency, but it was said that "DAIV-DGZ510S10S1-SH2" could be played comfortably enough.Then, we asked each part of the officials why the VR work was exhibited at the film festival this time and how it was difficult to create a 8K VR video work.
First, we asked Mr. Katsuya Ogino (hereinafter referred to as the title omitted) of the Saitama Prefectural Industrial Labor Department Commercial and Service Industry Support Division for the film festival.
Mr. Katsuya Ogino of Saitama Industrial Labor Department Commercial and Service Support Division
The editorial department First, please tell us what you started to handle VR.
Ogino Saitama Prefecture opened Aya's Country Visual Plaza (including facilities such as video museums and video public libraries) in 2003, and has supported young video creators as a base for video -related industries.2016 is called the first year of VR, and new visual technology such as VR and AR has been attracting attention.
Editorial department What kind of efforts will be done using VR and AR in the future?
With the support of Ogino Saitama Prefecture, the developed creators create VR and AR content, and various business companies in Saitama Prefecture use VR and AR images to PR in their own products and products.I want you to use it.By doing so, I would like to lead to the promotion of industries in Saitama as a whole.
Is it part of the fact that VR was handled at the editorial department film festival?
Ogino: Well, as the first project, we first create one VR work, exhibit VR works overseas, and get to know what VR is like, and want to use VR video.It was implemented from the idea that I would like to have it.
First of all, we talked about the production of 8K VR, which was exhibited as a highlight, about the production of the planned film festival, because we want to expand the recognition of VR.
CEO of Alpha Cord Co., Ltd. CEO and CTO VR/MR Content Producer Takuhiro Mizuno (right) and Minori Hayashi (left), the company's VE Planner.The following is the title omitted
Editorial Department This 8K VR video is used to shoot what kind of camera and the merit of shooting with that camera, please let us know.
Mizuno: This time, I used a camera called GoPro Omni to shoot a video that looks carefully on a fixed point.Some cameras have a wide dynamic range that combine a larger camera, but GoPro Omni has a better frame synchronization than such a camera.During the work, a quite fast dance called contemporary dance is performed, but when shooting such fast movements, if the frame synchronization is not solid, the movement will be shifted and stitching (adjusting the video) will be difficult.It will be.
Gopro Omni used for shooting
The image produced by the editorial department is 8K, which is highly resolution, but please tell us the points you have difficulty when creating such an ultra -high resolution VR video.
Hayashi: Yes, when it comes to 8K images, the data is very heavy, so it was hard just to move one frame.The PC used for editing was the Core i7, where the CPU was the highest performance a year ago, and the graphics used six GeForce GTX 1080, and the storage was six of the Sandisk EXTREME PRO and RAID 0.
When editing a heavy video of the editorial department data, what is the part of the bottleneck as a PC specification?
If you only cut and paste Mizuno video, it seems like a problem of reading and writing of storage, but this video was an Adobe Premiere Pro and had 8 tracks, but when the number of layers increases, CPU and GPU.I think that the performance is also required.In the case of PREMIERE PRO, depending on the plug -in, it is quite different whether you use the CPU or GPU, so it does not mean that either one is not good, so it is desirable that both performance is high.This is especially true for VR.
The company's "VRIDER" is optimized for live -action, and it is a part of the function, and a virtual speaker is freely installed in the application, and separately flows in sync with the video separately from the three -dimensional sound already incorporated into the video.It is possible.In addition, it is possible to display the title that follows the gaze before the video playback, and that when the experienced person wears VRHMD, it is possible to confirm that the video is output immediately.
Editorial Department By the way, the video is H.264 and H.I wonder if the appearance will vary depending on the compression standard such as 265, but which compression standard is used in this video?
Mizuno: In the case of ourselves, it is not such a spatial compression, but a format of almost reverse compression.For this reason, the compressed format is to take a high bit rate and lower the CPU load.H.264 does not support 8K due to specifications, so H.As 265 spreads, the required specifications may change.H.In 265, we have not yet made VR video production, so I would like to use it someday, but spatical compression crushes the details and secures a big appearance, so it is inevitable out of large images.I feel that it is not very suitable for VR, which is expanded and watched.However, if the quality rises and the optimization is performed, H.I would like to use 265 to distribute Internet.
Editorial department In the current method, is the data still heavy and useless?
Hayashi: Even with this 5 -minute video, the capacity will be about 67GB, so it cannot be distributed to the Internet.
Editorial department It is amazing capacity.So, can I play 8K images with a VR headset for smartphone or PlayStation VR?
Mizuno: It's still in research, and the current situation is still only 4K output.However, those who are working on the operation are taken with a 4K camera, but the 4K video taken with a 4K camera and the video taken at 8K and down to 4K is more beautiful.You can see it, so if you shoot at 8K, you can watch as much native view with the current HMD.On the other hand, even if it is a video to be watched with a VR headset for smartphones, it is better to downside the 8K video rather than shooting with a 4K camera.In particular, VR videos will be displayed in part of the video, so if you shoot in 4K, the details will be crushed.
The editorial department, that is, the most beautifully watched VR videos, it is better to use Oculus Rift or VIVE on a VRHMD connected to the PC.Then, this time, we use mouse computer DAIV to play VR videos, but could you tell us about the merits and the points that were good to regenerate 8K VR?
The video of the forest 8K is still heavy, but the PC I borrowed this time is perfect for the basic specifications, but the storage is equipped with an Intel high -speed SSD, especially the video is stable.I'm glad I was able to play.
Mizuno: At the time of the event, you will be released in full power, and at this kind of event, some people are new to see the VR video, so it can be operated stably.I thought it was quite important.Also, the mouse computer DAIV has a caster (DAIV option) on the PC case, but it was convenient to carry such an event.
The editorial department, the more.VIVE is used this time with VRHMD, but is there any reason you used VIVE?
Mizuno: Is it easy to wear?There are many good aspects in Oculus Rift, which is a competition, but we have VR content regardless of age or gender at all ages at various events, but they have to wear them with glasses.Considering the requirements such as quickness, if you use it at the event, VIVE has a longer day.
The production of high -quality VR images is still developing, but the PC used in the event requires a high specifications and a cooling performance and durability that can withstand long -time operation.At that time, the DAIV series, which has high performance, high cooling efficiency, and excellent maintenance, seems to be perfect.
Finally, we talked to Toshi Hirose (hereinafter referred to as the title omitted), a producer of Digital SKIP Station Sales Promotion Department, which planned the production of the video.
Digital SKIP Station Sales Promotion Department Producer Toshi Hirose
The editorial department Please tell me what is the concept of the 8K VR work of "Shoot ANIMA!"
Hirose "Shoot Anima!" As the first story has risen, Saitama has launched a VR -related human resource development project.Based on that, I hope that it can be used for lectures, such as what kind of cut split and how it can be expressed in such a human resource development.
Please tell us the points that were Kodawa, such as switching the scene of the editorial department.
Hirose video is divided into three cuts.Conventional general video works have been forcibly induced visual by connecting cuts, but in the case of VR, you can look around 360 degrees, so you can select a viewpoint.Therefore, in the first cut, the user's perspective is guided by directing, moving back and forth.
The editorial department Certainly, you've been running around while dancing.
One performer on board 8K VR works.In the first cut, the production is performed to dance a little far away and guide the viewer's gaze according to the left and right movements.It was a video that seemed to be a bit white, probably because of the exposure, but the details were more detailed than any VR video I've seen so far, and the outline of the person was outstanding.
Hirose Next, in the second scene, the scenery scene is synthesized in the background, but when I suddenly moved to a different space, I wanted to see how the user reacts, from the first cut.By gaining a sense of openness, it creates the theme of what kind of feeling will be received.
In the second cut of the editorial department, the landscape changed from day to night.
In the second scene, the background video changes to a landscape.At the feet, the sky and performers are projected like a mirror, and the wide view with a depth creates a sense of openness.He gave a fantastic and elegant impression
Hirose: I also created the difference in the time axis, and also thought about how to react.And finally, I came back to the studio, but this time, in order to emphasize the realism of VR, the performers move in front of them and how they feel the reality.I am doing it.
In the last scene, shift to the studio again.The performers are approaching and gaining a high reality.In the conventional 4K video, I was able to see the expression of the performer who seemed to be crushed, and I felt that it was a high resolution of 8K.

In this video work, various devices were performed on the connection of the three cuts, but since the shooting was performed separately, the stitching that would naturally connect when the video was switched was difficult.Also, in the current VRHMD, there are various issues, such as the fact that the lens lattice is concerned, no matter how high the image is created, and the camera is also automatic exposure in a dark scene, and the image quality is inevitable.
In this way, the VR video field, such as new attempts such as 8K VR, is definitely going to evolve.In response, it seems that the necessary PC specifications and software are optimized.I hope that such problems will be clear and you will be able to enjoy VR video works that will give you a high quality and surprise.
