OER16 Edinburgh Abstract Application



Please see below our application for the OER Open Education Conference :

OER16 19-20th April 2016. This year our theme is open culture and it is being hosted by University of Edinburgh, Scotland

Innovative approaches to opening up cultural heritage collections for education 

Having researched and examined how Open Source has reached out into many areas of education I was struck by how little education exists for Open Source in tandem with the Film Production community. It seems little has been developed for an entire production workflow from the sensor and how it is used and manipulated, the colour science and the workflow (utilising both software and hardware). 

Examples exist such as ACES (Academy Color Encoding System) providing a free, open source colour and look management architecture. http://www.oscars.org/science-technology/sci-tech-projects/aces through the educational department of the Oscars.org, and has been taken onwards by Universities in the USA, but being such a new subject has as yet to appear as an Academic reference. Thus seeking to further the understanding and appreciation of production processes we can create a diverse array of programs for students, teachers, filmmakers, scholars and institutions to provide unique opportunities for engagement with the principles of Open Source relating to Film Production and by approaching the subject now and introducing education and research with an ethical ethos and approach the belief is that we can educate further those who would like to see Open Source become stronger and a more realistic proposition as it continues to thrive and develop. Learning, teaching and research are all encompassed in the entire pipeline for a production. Open Content, Open Practice, Open Data, Open Access are all elements that can be attributed to Open Source for Film and education. 

The aim is to create free and open technology, and make all the generated knowledge freely available to everyone, encouraging participation along the way. By developing this approach we can create an educational pathway that includes subjects such as open data, open collaboration and open hardware and software. As I can envisage new approaches to Film Education, it is clear that at some intersection Open Source will have a valuable role to play. New emerging fields of research are developing based on Colour Science and Colour Grading, effecting Cinematography. New information in assessing how we develop film for the digital age is changing and Open Source will have a major impact here. 

By teaching new ways of working that would previously be the benefit of a few we can now broaden the education to many more encompassing all this new information. My idea of how to change and introduce a new approach to Film Education is with an Open Source ethos and developing reliable influence testing, scholarships and a new colour science unit. We will be designing, creating and developing OpenFlow as a new suite of workflow and software development tools for the entire film production pipeline. Sensor processing, bayer patten development http://www.ece.ncsu.edu/imaging/Publications/2002/demosaicking-JEI-02.pdf with software development would all be encouraged to teach and educate on how these processes actually work, having a huge impact and why we approach production roles in a certain fashion, creating deeper knowledge and better understanding for future engagement, educationally and professionally. 

In summary it is my belief that Open Source Film Production is an emerging environment effecting education tremendously, is a perfect example of collaboration and education developing in multiple areas for the future and can all be developed with an extremely strong emphasis on education.

Current Axiom Development Status (Jan. 20th, 2016)

Current Development Status (Jan. 20th, 2016) 

Watch this space as we will try to constantly keep it up to date with the most up to date AXIOM Beta development and production information. www.opensourcecinemauk.com

The camera internal webserver is up and running an can already serve image sensor register tables as well as Piecewiese Linear Reponse (PLR) HDR curve graphs. Color science related tasks like color calibration, non-linearity measurements as well as fixed pattern noise compensation, etc. are in full swing already. The final PCB revisions of all boards for the Early Betas have been received from OSHPark and after assembly have been tested and verified. The hardware seems to be free of design faults or bugs (as far as we can tell) and the camera is able to operate and work flawlessly from a hardware point of view. Not every single hardware component has been thoroughly tested in every possible operation mode so there is still a small chance that minor problems will be identified in the future - but we are rather optimistic everything is in order. We are also making progress with creating testing hardware that runs automated verification on the electronics for quality assurance. HDMI live output is working as well as recording high speed bursts into RAM - the sensor runs on a lower than max clock frequency so from the software side performance is set to increase over time. A small batch of Early Betas for developers and early adopters is currently being assembled manually by our team - which is a bit slow but automated assembly for such low quantities just makes no sense financially. Once those vouchers have been fulfilled the next production batch will start.

Camera shield slots

Shields

The name shields was inspired by the Arduino plugin boards that are also called "shields". The AXIOM Beta sports two shield slots with space for connectors going to both sides of the camera. In contrast to modules the shields in the Beta have slow and medium speed interfaces to the main processing FPGA and therefore are perfect for tasks like: trigger IN/OUT, genlock IN/OUT, timecode IN/OUT, sync IN/OUT or connecting external sensors or buttons, LCDs, etc.


PCIe Modules slots


Modules

The AXIOM Beta has two high speed module slots with PCIe connectors (these are not really PCIe cards, we just utilize PCIe for the connectors). Each module has a total bandwidth to/from the main processing FPGA of at least 6 Gbit/s. This makes the modules perfect for dealing with high bandwidth video outputs like HDMI/Displayport/SDI. Due to the flexibility this could also allow to create a solid state media recorder as a module in the future. For now the AXIOM Beta relies on external recording though.



Camera Beta Modularity - PCB


PCB Stack

The general approach for creating the AXIOM Beta hardware and PCB stack design was to give every board a clear core purpose and not just pack as many things onto each board as possible just because there was space left. This way each board can be replaced without affecting the rest of the PCB stack - for example as the interfaces between the boards are predefined a new image sensor can be implemented by just changing the Sensor Board. This gives the entire assembly a very sustainable future as any board that is not up to date anymore can be replaced by a newer one and any board that breaks for whatever reason can be swapped without requiring to change the rest of the boards in the camera.

AXIOM Ecosystem : OSFP-UK details


AXIOM Ecosystem

AXIOM Ecosystem


Introduction

The ecosystem of the AXIOM Modular Cinema Cameras acts as a hub to actively communicate that individual services and developments are welcome. It stimulates future developments around the cameras (as well as related services) and to offer an early communication-platform for already planned developments. The initial launch of the AXIOM ecosystem is used to collect feedback from the community to subsequently further develop and improve the system in the future.

No license fees & No royalties


As the AXIOM and apertus° philosophies are build on a fundamental Open Hardware and Free Software approach there are no license restrictions limiting the ecosystem. Anyone can offer services or products in the AXIOM ecosystem and there are no royalties to pay.
