General

1What is Volumetric Video?
Volumetric Video is a filming technique that makes it possible to directly capture images in a 3-dimensional space. This technique enables you to create realistic human performances without having to resort to creating time-intensive computer animations. The HOLOSYS, a product by 4D Views, does this by simultaneously capturing the subject from multiple angles in a green screen environment.
2Can I use the rendered product for 3D applications only?
No, you can use the rendered product for applications such as AR, VR, MR, 360° and 3D videos, as well as for 2D videos.
3What are the advantages of Volumetric Capture?
While an ordinary green screen will only allow you to shoot 2D images, Volumetric Capture allows you to shoot 3D images, to be put to use in both 3D as 4D applications. This is especially valuable if you want to create 3D assets for video games, AR, VR or VFX. Even better: as the HOLOSYS creates this 3D footage in real time instead of animating it in post, small details such as wrinkles in the face or the movement of fabrics look much more natural. To achieve this high level of accuracy through animation would be very time-intensive and costly compared to how easily the HOLOSYS can capture and render images in 3D.
4What are the limitations of Volumetric Capture?
The HOLOSYS is based on color video sensors only, giving a large flexibility of filming subjects. Any material that is not transparent or relatable to the studio environment (large reflective surface and green color) is compliant with the HOLOSYS. It also is not possible to capture objects smaller than 1cm.
5Where is the studio located?
4DR Studios can be found at the Effenaar, a well-known multi-functional music venue that invests in technological innovations for the benefit of cultural experiences such as 4DR Studios. The Effenaar is located at the heart of Eindhoven, at small walking distance from Central Station. The portable studio will be set up for your shoot at the main concert hall on the first floor. For your convenience, 5 dressing rooms, an artist foyer and a nice restaurant are available at the premises. Our viewing room, located on the balcony above the main concert hall, gives you a perfect bird’s-eye view of the studio. Parking is possible at the back of the Effenaar as well as across the street. For heavy equipment you can use the loading dock at the back of the venue. This also gives you access to the cargo elevator.

Pre-production

1Do I need a fully developed script to film at 4DR Studios?
No, 4DR Studios offers its services from pre to post-production. Together with you we will thoroughly discuss your idea and develop a script and plan in accordance. 4DR Studios can take care of all the planning involved and will create a detailed production bible for the realization of your idea.
2Can I do the pre-production myself/externally?
Yes, but only if you have proven experience in Volumetric Video Capture and 4DR Studios is consulted and has found the plans feasible. Otherwise, since Volumetric Video Capture requires a specific approach, the risk of making irreparable mistakes becomes too high. This is why 4Dr Studios is actively included in the pre-production phase to implement our expertise in Volumetric Video Capture regarding production technicalities.
3Why does 4DR Studios offer pre-production services?
4DR Studios aims at providing access to Volumetric Video Capture for all, not just the elite few. To make this as approachable as possible, we offer our expertise in all production phases, from start to finish. This way, we hope to lower the threshold for the high-tech innovation of Volumetric Video Capture.
4Do you also provide green screen props?
If your production is in need of specific props for green screen, such as furniture or other objects to be edited in later in the process, 4DR Studio can provide or even handcraft these for your convenience.

Production

1Who is part of the 4DR Studios crew?
Our crew solely consists of highly qualified professionals that are properly trained in the mechanics of Volumetric Capture. On site we will provide you with a Director, DoP and Studio Manager. On request we can also provide you with a Technical Director, Sound Mixer, Gaffer, Assistant Director, Makeup Artist, Hair Stylist, Prop Maker and so on. Any other specific wishes regarding personnel on site, are always open for discussion. In post-production we offer the service of Graphic Designers, AR Developers and Editors to process the .4DS data in Unity or Unreal before delivering the footage to you.
2What are the audio options?
If needed, we can provide several different audio capture setups according to your wishes. Additionally, an audio mixer to utilize options such as lapel mics and boom mics can be hired for the shoot. We can record in Stereo as well as Ambisonic and Binaural for a 3-dimensional sound field.
3Can we add our own lighting?
Yes, this is possible, but we do not recommend it. The studio is fully equipped with LED lights to provide the perfect balance for Volumetric Video. Adding or changing lights could result in inconsistencies.
4How many people can be filmed at once?
As far as we know, the highest number of people being successfully shot at once is 3. The important thing is that one person does not obstruct any of the other camera’s views on another person. It is however possible to add several individual captures to the same scene after rendering.
5How can we view the footage?
We provide a constant 2D live feed through one of the Director’s cameras. During the shooting we also run a preview screen in our viewing room. Here you can sit and watch the shoot both on a screen and in the studio with a bird’s-eye view. If you want to review your footage in 4D, we can render a frame after a take. This will take around 5 minutes.
6What is the standard process for a shoot?
Before the HOLOSYS is ready to record, it needs to be calibrated, which will take about 3 minutes. It is recommended to calibrate regularly in between sequences to assure the correct allignment of the cameras. The Director and DoP, who operates the HOLOSYS, will keep track of the sequences. After a take, the DoP can process a preview sequence of few frames in 4D, to validate technical or artistic concerns. Because of the large amount of data produced, it is important to be selective regarding the shots you want to keep and send to render.
7How much footage can be recorded in 1 day?
We can record up to 90 minutes of sequences (@30 FPS) a day. For a high-end production, this will provide you with roughly 2 to 2,5 minutes of final video after editing, depending on how selective you are in which sequences you want to send to the batch to render.

Post-production

1To what format is the rendered output exported?
Our system has 2 different outputs. The default output is .4DS format, which is compatible with Unity and Unreal Engine. This filetype is consistent with most common XR devices, including Oculus, HoloLens, HTC Vive, iOS and Android smartphones, etc. The output can also be exported to .ABC format, which is consistent with recent CGO software such as: Autodesk Maya, 3ds Max, Blender3D and C4D.
2What services does 4DR Studio offer in post?
4DR Studios can provide you with an asset, scene or finished product/application. This means that 4DR Studios can provide you all production services, starting from post-production up to the finished project, and from editing to VFX design. Under certain conditions and upon request raw footage can be provided.
3Can I resell the files to third parties?
Only high-end finished products may be sold to 3rd parties.
4How does editing in 3D differ from editing in 2D?
Compared to 2D filming, it is a lot more difficult to repair impurities in post for 3D filming. This is why it is very important to be well-prepared, alert and selective about your shots during a production. Editing by 4DR Studios is done in default with Unity.

Technology

1How long does it take to render?
The HOLOSYS standard processing time is 10hrs for 1 minute of data (@30 FPS).
2What is the capture volume of the HOLOSYS?
The HOLOSYS can record up to 3m in diameter and up to 2.4m high.
3How much space will a file take up?
This depends on the quality of the file. For optimized mobile quality @30 FPS the file would take up around 15MB per second, whereas if you want a high-quality desktop format at 30fps it would take up around 30MB per second. If you want the highest quality for i.e. VFX @60 FPS this could go up to 300MB per second.
4Camera & Lighting Specs
The Volumetric Video Capture stage has 32 calibrated RGB cameras and 24 5600 LED lights.
