Virtual production (VP) is swiftly becoming a pivotal technique in the film and television sector, offering filmmakers innovative approaches to craft captivating content with increased flexibility and efficiency. But what exactly is the meaning of virtual event production?
At its core, virtual production merges traditional filmmaking techniques, such as motion capture and facial recognition, with cutting-edge digital visuals. This revolutionary technology opens exciting possibilities for directors and producers seeking to breathe life into distinctive creations. Projections indicate that by 2027, the virtual production market is anticipated to generate revenue of USD 5.1 billion. In this blog, we'll explore the workings of VP and the benefits it brings to content creators in today's dynamic landscape.
What is Virtual Production?
Virtual production is a filmmaking strategy that blends physical and virtual elements, utilizing technologies like CGI, augmented reality, motion capture, and real-time rendering. It enables the creation of realistic environments and effects on a virtual set, providing filmmakers the flexibility to design landscapes, sets, and creatures while reducing costs. By leveraging real-time 3D engines and expansive LED screens, VP allows for the creation of instantly visualized and adjustable photorealistic sets. This technique has gained popularity in the film and TV industry for its time and cost savings, heightened realism, and potential for immersive storytelling. As VP evolves, it is poised to transform filmmaking, providing filmmakers with increased creative control and efficiency.
How to Establish a Virtual Production Studio in 2024?
Setting up a virtual production studio requires a shift in perspective towards a non-linear production process, incorporating tools such as game engines. The versatility and interactivity offered by virtual worlds within these engines, coupled with the ability to visualize content early in the production phase, present new opportunities for refining creative visions.
Noteworthy films like Lion King, Ripple Effect, and Mandalorian have harnessed game development technology in their production. Adopting a game engine for VP demands a high level of coordination, resembling the process of creating a video game. This approach deviates from a linear process, requiring teams to access extensive information early in production and utilize various tools for iterating on ideas throughout the entire process.
How Does a Virtual Production Studio Work?
The typical VP process involves the following steps:
1. Pre-production: Generate virtual assets, including 3D models, textures, and animations. Plan scenes and shots intended for filming on the virtual set.
2. Virtual Set: Instead of traditional physical sets, VP utilizes large LED screens or projection systems to display high-resolution images or videos, creating realistic backgrounds for actors.
3. Real-time Rendering: Powerful game engines like Unreal Engine or Unity render the virtual set in real time. This immediate visual feedback allows filmmakers to see the virtual environment and characters as they appear in the final shot.
4. Motion Capture: Actors may use motion capture suits or markers to capture their movements, which are then used to animate virtual characters or objects within the virtual environment.
5. Live Compositing: The real-time rendering engine combines live footage with virtual elements, seamlessly integrating the physical and virtual worlds during actor performances. This real-time composition reduces the need for extensive post-production.
6. Iterative Process: Virtual production enables filmmakers to make on-the-fly adjustments during the shoot, including modifications to lighting, camera angles, and virtual elements. This flexibility saves time and enhances creative control.
What Is Required To Set Up A Virtual Production System?
Key steps to set up a VP system include:
1. Camera Tracking Technology: Utilize tools like a virtual reality headset and tracker, such as HTC Vive Pro, to track camera movements relative to the LED wall.
2. iPhone and iPad: Leverage Apple's latest devices equipped with LiDAR sensors for in-engine camera movement, synchronized with the Unreal iOS app.
3. Real Cameras and Lens: Consider high-quality cameras like Blackmagic Design URSA Mini 4.6K Pro G2.
4. Camera Rigs: Facilitate accessory addition with a recommended rig like the Neewer DSLR Shoulder Rig.
5. Capture Card: Stream live camera footage to the computer with a suitable capture card, such as Elgato Cam Link 4K or Black Magic Decklink 8K Pro.
6. LED Walls and Volumes: Utilize graphics cards like RTX Quadro for LED walls or volumes, depending on the production scale.
7. Green Screen: A cost-effective alternative to an LED wall is a green screen. Ensure a smooth surface with even lighting for quality virtual production.
8. Unreal Engine: For creating the digital world, utilize an industry-standard game engine such as Unreal Engine 5. Access additional assets for the digital world through the Unreal Engine marketplace.
Conclusion
Undoubtedly, virtual production technology holds a promising future in the motion picture industry, potentially transforming how filmmakers approach their craft. The ability to work swiftly and effectively in creating realistic and detailed images might lead to reduced production expenses, granting both indie and studio filmmakers increased access to funding. As this technology gains traction in larger productions, it wouldn't be surprising to see independent films incorporating virtual production techniques in the near future.
