A stand-alone subject of the film projectionist curriculum, and the one every cinema operating today depends on.
The digital cinema chain, end to end.
Grain gave way to the pixel, and with it came a standards-driven world where a screening either conforms or does not play. This subject covers image formats and resolution, the DCI specification that defines what digital cinema is, and the DCP - what a digital film print actually consists of, how it is mastered, how it is distributed and how it is secured.
From there it moves to the architecture of a digital cinema: servers, media blocks and playback, the content security chain of keys and keys that decides whether a film plays at all, and how a single screen scales up to a multiplex under central management.
The last part deals with what is arriving next: light sources, projector design, 3D systems and the modern technologies now moving into cinemas. The aim is that the knowledge does not expire the year after you finish. Purchase grants a non-exclusive licence for 12 months from the date of purchase.
A digital screening fails differently from a film one. There is no torn perforation to find - there is a key that expired, an ingest that did not complete, or a certificate that does not match. Knowing the chain is what makes those faults solvable before the audience is seated.
Available on its own, or as part of Digital Cinema (€300, saving €60), or Complete Projectionist (€540, saving €180).
The subject runs in three parts. Each part is a self-contained block of lessons closed by a knowledge check - passing it is required to move on.
Digital Projection
Part 1
history of digital projection, image formats and resolution, DCI, the DCP
Part 2
content security, categories of digital projection, DCP mastering, distribution and playback, digital cinema architecture, the multiplex
Part 3
light sources in digital projectors, projector construction, 3D technologies, emerging areas of digital cinematography
Part 1 in detail
History
the arrival of digital projection, the transition of the cinema network, and what was gained and lost in it
Formats and resolution
2K and 4K, containers and aspect ratios, frame rates, colour space and bit depth, HDR and high frame rate
DCI
what the specification requires, compliance testing, and why a standards-driven chain behaves the way it does
The DCP
the structure of a digital film print, JPEG 2000 and MXF, packing lists and composition playlists, supplemental packages
Part 2 in detail
Content security
encryption, KDMs, certificates and trusted devices, forensic marking, and the most common reasons a film will not play
Categories of projection
D-Cinema and E-Cinema, what separates them, and where each belongs
Mastering
from the finished master to a compliant DCP, subtitles and audio configurations, quality control and validation
Distribution and playback
physical and electronic delivery, ingest, building a show playlist, automation cues, and running the screening
Architecture
servers and media blocks, integrated and separate designs, storage and networks in a single-screen cinema
The multiplex
central library and scheduling, theatre management systems, distributing content across screens, monitoring and reporting
Part 3 in detail
Light sources
xenon, laser phosphor and RGB laser illumination, brightness and colour gamut, lamp life and running costs
Projector construction
DLP and the DMD, imaging engines and prisms, cooling, lenses and lens memory, alignment and routine maintenance
3D technologies
polarisation, spectral separation and active shutter systems, silver screens, light loss and ghosting
Emerging areas
direct-view LED screens, premium large formats, high dynamic range and high frame rate, and where the technology is heading
Lessons combine video lectures, illustrated reading and interactive elements, available 24/7. Knowledge of the most important concepts and principles is checked by tests throughout, and passing them is a condition of progressing through the subject. A certificate of completion is issued on finishing.
Practice with a real projector and server matters, and it cannot be arranged remotely. You get guidance: what to arrange in a local cinema, what to ask for, what to try, and how to document it. After completing all the courses, you should be fully prepared to start your own practice.

Knowledge of the digital film print is indispensable in every cinema operating today. In a single-screen venue it is the whole technical job: ingesting a DCP, managing keys, building a playlist, running the show and fixing what goes wrong before the audience notices. In a multiplex it extends to the theatre management system, the central library and the scheduling that keeps a dozen screens supplied. In festival technical production it is the same work compressed into days, with unfamiliar content arriving late.
Beyond the booth, these are key skills across the whole life cycle of a film: production and post-production, grading and mastering, international and local distribution, and finally projection. The same standards apply in broadcast and in archive digitisation, where film material is converted into digital form and has to end up in a format that will still be readable and screenable in decades to come.
Digital Projection is one of six subjects covering the whole projectionist trade. It assumes what Film Optics teaches about light and lenses, and pairs with Audio Technology, which carries the other half of the screening.
When does the course start? Are there fixed dates?
The courses are entirely online and self-paced. You decide the start date and the tempo.
How does the course work?
Each subject is a structured sequence of lessons that takes you into the material and explains each topic to the depth the trade requires. Lessons combine video lectures, reading and interactive elements. Knowledge of the most important concepts and principles is checked by tests throughout, and passing them is a condition of progressing - so that finishing the subject means something.
What do I need?
A computer or tablet with an internet connection, and the willingness to work through the material properly. There are no entry requirements - the courses are built to be accessible to complete beginners while still adding something for people already in the trade.
Do I need to know anything about film projection to take this?
No. Digital Projection stands entirely on its own - if you never intend to touch a film print, this is the subject that matters. It does assume some understanding of the light path, so
Film Optics makes a good companion, which is why the two are bundled together.
Will this go out of date?
The DCI chain has been stable for years and is not going anywhere. The final part is deliberately devoted to emerging technologies - laser illumination, direct-view LED, HDR and high frame rate - so that you finish with a sense of where things are heading, not just where they stand today.
Is there any practical training?
Not as part of the course. Practice with a real projector and server matters enormously, and it cannot be arranged remotely - you get guidance: what to arrange, what to ask for, what to try, and how to keep a record of it. After completing all the courses, you should be fully prepared to start your own practice.
Do I get a certificate?
Yes. A certificate of completion is issued for every subject you finish, listing the subject, its scope and the hours involved. It is a record of training, not a licence to practise - no such licence exists in most countries.
How long do I have access?
Twelve months from purchase, for each subject you purchase.
Can I take an examination?
This projectionist training has a formal counterpart in the Czech Republic, where it prepares candidates for a
state-recognised professional qualification examination, leading to a certificate with a Europass supplement. That examination is held in person and in Czech, so it is realistic only for candidates who can travel and speak the language. Everyone else should treat these courses as what they are: the knowledge itself, certified by us.
There are no entry requirements for this subject - no prior study, no qualification, no experience in a cinema.
What you need to study
Equipment
a computer or tablet with a stable internet connection
Audio
headphones or speakers for the video lessons
Time
roughly 8-10 hours per part if you want to work through it briskly - less if you take longer, which you are free to do
Helpful, but not required
not required, but taking it first makes the sections on light sources, lenses and image geometry easier to follow
Computer literacy
general familiarity with files, storage and networks - no IT qualification needed
Access to a booth
a cinema where you can look at a real projector and server while you study
Purchase grants a non-exclusive licence to the e-learning course for 12 months from the date of purchase.
