No matter the size and breadth of a traditional video production,
one of the most important findings is that a startling number of the extras
you'd traditionally find on a movie or television set aren't actually required
to be there. Director, DP, Producer, Camera Operator, Actors, Gaffer,
Production Designer, etc. are just a few of the crucial positions that are
frequently required. In the world of virtual production, the list is mostly the
same, but there are a few new roles on the roster. The majority of personnel,
which are referred to as the Brain Bar collectively, are technicians needed to
set up and manage this novel technology.
Rapid alterations and adjustments are to be expected,
especially since this new model has had such a significant impact on
manufacturing at every level, given that virtual video production with LED
quantities is still very much in its infancy. New workflows will include the
knowledge gained from experiences in the real world. The use of tools will be
improved, updated, or even changed. There will be a strengthening of abilities
and a finding of new avenues.
What is meant by virtual production?
Virtual production is a technique for making movies that
merges the virtual and real worlds.
The green screen is certainly something you've seen before.
It's a tool that editors frequently employ in the backdrop of a shot to make it
simple to add visual effects later on.
The green screen is swapped out by a huge LED screen in
high-end virtual production. These screens' high resolution renders any films
or images that are displayed on them to appear extremely lifelike.
Virtual production techniques include using LED live walls
as one example. A couple more are performance recording and visualization.
Where virtual production first began
Front and back projection techniques served as the
foundation for virtual production.
The 1930 motion picture Liliom was one of the first to
employ back projection. 2001: A Space Odessy, directed by Stanley Kubrik, was
the first film to use front projection. The 2013 video game Oblivion made
excellent use of this technology as well. On a big white muslin cloth, a steady
video of the sun and moving clouds was displayed while the movie was being
filmed.
Performance capture and visualization methods including
previs, postvis, and techvis are additional types of virtual production
technology.
A computer-generated 3D character is created via performance
capture, which records an actor's performance. In the 2002 Lord of the Rings
film The Two Towers, Andy Serkis' actions as Gollum were initially captured
using the technology.
Let's now discuss visualization approaches in more detail
and explain what each of the three techniques is.
1. Previs is a step in the production process. It involves
storyboards, storyboard animation, concept art, and anything else that aids in
the development of the movie's plot.
2. Previs is followed by techvis. The technical elements of
previs, such as camera settings, shot locations, and essential green screen
dimensions for CGI scenes, are handled by techvis artists.
3. In post-production, a process known as postvis,
live-action scenes are combined with short-term visual effects to act as
stand-ins for the final cut.
Tim Burton's Batman Returns, which was released in 1992,
featured an early iteration of this previsualization. The movie Gravity from
2013 was the one to advance this technology and visualization methods:
Gravity - With the aid of extremely finely detailed computer
graphics, the sequences in the film Gravity were shot by shot previsualized.
The Light Box, another remarkable advancement in VFX (visual effects), was also
included in the movie. This container stood 20 feet tall and contained 4096 LED
lights.
These lights were programmed by the crew with moving images
of Earth and space. The performers could see what they were responding to in
the film when they glanced at the visuals that were displayed by the LED lamps.
Additionally, the lights gave the right lighting for various images.
Gravity pushed the limits of visual effects; the performers'
faces were the only really real objects in the majority of the big shots.
Later films like Rogue One and Solo also employed the same
Gravity-inspired technology for dynamic lighting effects to illuminate the
actors' faces. Additionally, these movies made use of huge laser projectors and
projection screens.
The 2019 The Lion King movie's development saw one of the
biggest advancements in virtual production. Cinematographers used real cranes,
Steadicam rigs, and drones to operate virtual cameras throughout the whole
movie, which was shot entirely in a digital environment.
The Mandalorian, a contemporary virtual production, uses LED
walls or volumes. Hyperrealistic visuals are displayed on these walls. This
technology was also employed in shows like Star Trek: Discovery and the
upcoming Netflix German series 1899.
Virtual Production Recordings' advantages
1. Lower Expenses
The custom of everyone arriving in the morning, leaving at
night, and occasionally hanging out on set until they are needed is also broken
by remote working. (Although being compensated.) Now that they have more
flexibility, remote workers may choose to return part of that flexibility to
you.
Virtual production eliminates the need for real sets by
generating digital backdrops. Because much of the labor is done while filming
in real-time, it also lessens the need for post-production and reshoots. All of
this significantly lowers production costs.
2. Decreases the Requirement for a Physical Location
Cast and crew do not need to travel to a physical place for
a virtual production. The crew also doesn't have to worry about external
illumination and weather fluctuations that could interfere with the production
schedule because everything is digital.
It's safe to say that some of us would prefer not to
commute, deal with rush hour traffic, or have to drive home after a long day at
work from a human standpoint. It makes sense that those of us who have
successfully recovered our lost travel time during the pandemic era and set up
productive remote working environments at home will be hesitant to give up these
advantages.
3. Working from Home
Since not every participant must be present on set while
shooting, virtual production permits remote work.
It's possible that they would have previously added a charge
for transit time and expenses, but they no longer have to do so as a line item.
Perhaps they might provide hourly fees rather than daily or weekly rates.
Without a doubt, you won't need to account for trip expenses and lodging
expenses. Going remote could therefore quickly reduce your manufacturing costs
and increase the agility of your initiatives.
4. Efficiency of post-production
Pre-production, production, and post-production are only a
few of the many processes in the filmmaking process, which is sometimes
compared to factory-line production.
Sadly, this system is ineffective. Any production error
lengthens the post-production process, and vice versa. For instance, the
director can film the scene improperly if he or she has trouble visualizing the
VFX creature that is supposed to be in the shot.
Without LED walls, the video production process may be too
uncertain. Additionally, fixing errors in post-production can be expensive and
delay projects.
Virtual productions, on the other hand, let you make changes
in real time. The director can request a real-time adjustment from the graphics
team if he doesn't like the virtual creature on the LED wall.
5. Decreased Set Time
Actors may find it challenging to see the final shot when
working on a green screen. LED walls, on the other hand, give the actors a
real-time view of their surroundings, reducing the need for retakes and the length
of time spent on set.
6. Creativity
Virtual productions provide countless opportunities for
creativity.
For example, VFX specialists can quickly alter the glow of
the sunset while filming. Or the sun could be entirely turned off. They can
make the mountain appear larger if the one on the horizon doesn't appear to be
intimidating enough.
7. Overall Business Benefits
The advantages for video production companies are just as
strong. Being able to cast your net across a much wider talent pool is more
advantageous than only hiring locally, regardless of whether your goal is to
identify the greatest talent possible, the least priced candidates, or simply
those who are available during your project window.
Which Positions Allow Remote Work?
The size of the project and the technology used will
determine whether a crew member can work remotely or not. It goes without
saying that you will need a pair of hands to move anything that needs to be
physically moved, whether it's replacing a damaged panel, altering the volume's
shape, or moving a camera. Even so, some physical apparatus can be built first
and then managed remotely.
1. Directors
The majority of the time that directors spend on site is
already spent gazing carefully at monitors before giving performers performance
criticism based on what they have just seen. Therefore, it is debatable how
much of this can be done using a video conferencing application and a livestream
from the camera. (Some of the latest episodes of the Disney+ series Obi-Wan
Kenobi were done in exactly this manner.)
Of course, it might not be possible to mimic the director's
manner if they like to approach the actors and demonstrate the physical parts
of their roles. However, not every production necessitates intense
actor-director communication. It may be sufficient for the director to be able
to watch and provide feedback from a place off-site for low-key projects,
talking heads, presentations, education, and corporate work.
2. Operators of the Environment, Engines, and Animation
These Brain Bar members have among the most evident off-site
jobs because there isn't much physical activity they need to engage in. They'll
need to see both the camera's video feed and an expanded view of the full scene
that they can control from anywhere.
Consequently, if someone points at the top corner and
requests that something be changed to a different color or that an entirely new
environment or lighting style be applied, someone can easily step in, and
effect the necessary changes in a matter of seconds—whereas, before now it probably
would have required several stagehands under the direction of the set designer,
with cherry pickers, safety harnesses, and health and safety supervisors in
place.
The old lengthy physical switchover between sets, which may
last days or even weeks, is replaced by a complete volume background
manipulation and change in just a few short seconds.
3. Lighting crew and LED techs
Although these roles differ in actuality, they are
essentially somewhat similar in concept. After installation, the lighting and
LED systems can both be controlled remotely. A well-designed lighting rig can
be managed remotely, and depending on the size of your production, you might
feel more comfortable having someone on set who can move things around when
necessary. However, with a full-scale volume, there is nothing to move.
4. Digital Imaging Technician
For some time, the focus of the DIT position has shifted
away from managing physical cards, shipping drives, and daily workflows toward
the flow of data.
Making ensuring that the original camera files and any other
captured material reach their destination has always been the goal. But the
tools needed to accomplish that aim have undoubtedly changed; RED's in-camera
Frame.io integration is only one example of how the media pipeline has rapidly
transformed.
Therefore, your DIT would be better off managing your
selected cloud-based pipeline, organizing the OCFs, system access, and footage
curation throughout the stakeholder hierarchy, rather than juggling media on
set. As soon as your cameras are connected, you can do it from anywhere.
5. Actors
Although it may seem like I'm pushing the meaning of
"remote" here, there are times when virtual production can turn the
performance into a distance-based activity. Simply not in the manner you may
anticipate. You don't trust me? What if I told you that none of the actors who
portrayed members of the Illuminati in Doctor Strange in the Multiverse of
Madness shared a single space?
Imagine for a moment that one or more members of your cast
are unable to travel to your virtual production site due to their location
abroad or an issue with their schedule.
Imagine being able to communicate the set design and
lighting configurations to a similar LED volume later or closer to the location
of your talent. Even though you recorded your actors' performances in separate
nations at various times, you may conceivably create a sequence that sets your
actors inside a scene convincingly if you're careful with your framing
decisions and there's little physical touch between characters.
What does a virtual production setup require?
Although the equipment needed to make high-end virtual
productions function is a vast improvement above what you'd find on a typical
set, the equipment required to make the remote portions of virtual production
function is simpler.
The following are the essential items to buy if you want to
set up a virtual video production environment.
1. Technology for tracking cameras
To track camera movement in relation to the LED wall, a
virtual reality headset and tracker like the HTC Vive Pro and Vive Tracker are
required.
2. iPad and iPhone
Thanks to their LiDAR sensors, Apple's most recent
smartphones are perfect for recording in-engine camera movement. The iPhone
camera's movement in space is picked up by these sensors. If you want to avoid
buying a camera tracker, this is really practical.
You can move your Apple camera around and have it change
camera angles in the virtual scene with the aid of the Unreal iOS app and these
sensors. For this to function, both your PC and Apple device must be connected
to the same wireless network.
3. Actual Cameras and Lenses
You can use any camera to capture the image, but if you have
the money, we highly recommend the Blackmagic Design URSA Mini 4.6K Pro G2.
4. Camera Rigs
You will want a camera rig so that you may attach extras to
the camera, such as the VR tracker. The Neewer DSLR Shoulder Rig is what we
advise.
5. Capture Card
Live camera feeds can be streamed to a computer using a
capture card. This is required so that the real-time footage can feed easily to
the game engine.
A high-end production card would be the Black Magic Decklink
8K Pro, while an entry-level card would be the Elgato Cam Link 4K.
6. LED Walls and Volume
Numerous banks of LED panel are used to construct LED walls
and volumes. An RTX Quadro-style graphics card powers each panel.
For those on a tight budget, we advise the Nvidia Quadro
6000 RTX, while the Nvidia Quadro 8000 RTX is recommended for high-end
productions.
Small production houses only need an LED wall; larger
production houses need a more expensive LED volume, which is recommended.
7. Green Screen
If money is an issue, consider using a green screen instead
of an LED wall. Just make sure the illumination is uniform throughout the
screen and there aren't many creases.
8. Unreal Engine
You will require a game engine, such as the
industry-standard Unreal Engine 5, to build the digital environment. Use the
Unreal Engine marketplace if you require digital world assets.
Both Unreal Engine and Unity are essential parts of virtual
production setups and, in the hands of a pro, are able to do amazing things.
They are also developing quickly, so keeping up with everything could require
some training. Because they were originally designed to be game development
engines, they also offer multi-user manipulation of active projects and
environments. As we all know, today's games are made to allow for seamless
communication between numerous remote players. Therefore, this fits perfectly
into the remote production workflow.
9. High-Speed Internet.
You'll need a strong and reliable connection with all of
this data flying around. It's reasonable to expect that if you work in a reputable
virtual production facility, they will be able to provide you with the
bandwidth you require, frequently with fiber to the building. Bonded modems and
a respectable mesh network will still get you where you need to go even if
that's not the case or if you choose to keep your set and communications
networks separate—especially if you're in a location with 5G coverage.
However, do yourself a favor and configure a wired
connection to your router or switch. While wireless internet is practical, it
also raises the possibility of packet loss, range limitations, and connectivity
problems—neither of which you want on a multi-hour shoot day.
What steps go into virtual production?
Let's examine the process of virtual production. In a
nutshell, the following will essentially occur in a virtual production:
1. The camera, the camera tracker, the LED wall, and the
game engine must all be set up before filming can begin.
2. The filming has now begun.
The scene must first be made in the game engine by the visual
effects team. Let's assume that the desert is the intended setting for the
scene. As a result, the group will have to build an engine rendering of the
desert.
When that is finished, the desert render will be shown on
the LED screen.
3. The actor is then positioned in front of a screen that
depicts a desert in a render. The actor appears to be in the desert when the
camera captures him with the LED screen in the background.
4. The visual effects crew can assist in making any lighting
or color corrections that are required in real time. Real-time editing in this
way lessens the need for post-production editing.
This is essentially how virtual production is carried out.
In Conclusion
We learned a lot about adaptability while we were under
lockdown, and the principles we learned are transferable to working virtually
on video productions. The fact that a new way of working is only getting
started may be the best thing. There has never been a better opportunity to
specify our methods of operation and the positions we decide to take up in this
fascinating new arena.
Being in the right place at the right time can still
determine whether or not you get the job. Just as "the right time" no
longer necessitates a two-hour trip, "the right place" can now be
anywhere with a respectable internet connection.
