Apertus Newsletter - June 2012
Greetings everyone. We’re still running on a super high after all the excitement surrounding our previous announcement. After winning the ‘Award of Distinction in the Digital Communities category’, we have been notified that the Ars Electronica Gala will be taking place on August 31st 2012 in Linz, Austria. Our Project Leader Sebastian Pichelhofer and Project Founder Oscar Spierenburg will be attending this, where they’ll receive the award on behalf of the entire Apertus Team.
13th Annual RMLL / LSM
The Libre Software Meeting is now one month away. If you’re in Europe, do yourself a favour and head to Geneva, where the largest International meeting for Open Source Culture will be up and running from July 7th - 12th. We’ll have a strong presence here, with three project members delivering conferences and discussions alongside our project related booth in the LSM main hall.
The following presentations will be delivered separately by project members Sebastian, Micheal and Sasha:
Apertus: The Birth of a completely Open Digital Cinema Camera - Tuesday 10th July, 9:40 am.
Sebastian Pichelhofer will be talking about the Apertus Project and explaining our goals to those who might be unfamiliar with the concept of ‘Open Source Hardware’. This talk will introduce Apertus to both industry professionals and the general public, with explanations of the technology being used.
Sample footage from projects shot with Apertus will also be included in this presentation.
Open Hardware and the Future of Cinema - Tuesday 10th July, 4:20 pm.
Micheal Green will be presenting on Open Hardware and the Future of Cinema. His intentions are to provide a clearer insight into how open hardware and software-based projects will revolutionise an industry currently based around closed-source hardware and software solutions.
In addition to this, he will be giving a demonstration of selected open hardware based tools that are currently in development.
The Community as a Power Source - Thursday 12th July, 2:40 pm.
Sasha Cohen will be discussing the best methods for fostering an online community and how such an audience may then be utilised to support the initiative (i.e an Open Source project) around which they have gathered. He will be using the Apertus Project as a primary case study for analysing how digital communication platforms have allowed a community of artists, engineers, film-makers and programmers to assemble and work together across the globe.
The Libre Digital Arts Festival- running in tandem with the LSM- will be based at the Kugler Factory. It will feature a large number of street events and meeting places, where performances and digital arts shows will be going down. We’ll be documenting our presence here and at the 13th RMLL / LSM with blog posts, video coverage, photography and forum related discussions.
The Conference & Workshop program can be found here: http://schedule2012.rmll.info/?lang=en.
The location of the venue areas are still being finalised. More details will soon be available at the festival’s Homepage: http://2012.rmll.info/en/home.
Alongside Sebastian, Micheal and Sasha, project core members Oscar Spierenburg, Juan Manuel Biaiñ, Philippe Jadin, Nathan Clark and Konstantin Kim will also most likely be in attendance.
Chronomotion
Whilst finalising the content for our Kickstarter Campaign, Project Leader Sebastian has been busy writing new software for motion-controlled timelapse cinematography. This software exists as Chronomotion and is primarily used to control the Merlin/Orion/Skywatcher remote head for shooting motion controlled time lapse. The software will allow custom bezier shaped movement curves with ramping and complex motion sequences. Please note that you require a special (TTL converter) cable to connect any of these devices’ heads to a PC serial port. A beta version has been released on Linux, Mac OSX and Windows.
Automated Transfer Scripts:
Project members Biel Bestue and Carlos Padial have been busy developing a new method for automatically copying and backing up all footage recorded via the Elphel camera. At present, Biel is developing this script to function more efficiently when transferring large quantities of files from the camera’s internal storage system to a separate HDD, SSD or PC.
If you’re interested in following this development, be sure to check out the related thread on our forums.

Kinoraw Developments
Simón Vialás- who is responsible for creating tutorials for everything that Kinoraw is investigating in regard to the Elphel camera- delivered a presentation on the importance open source software and open source hardware. He presented the Kinoraw project to the general public and then spoke about the Apertus project, alongside the intentions of both groups. This ten minute presentation was held amongst others involving the topic of creative commons content, which is at the very heart of the upcoming Barcelona Creative Commons Film Festival (BccN).

Open Source Film: Floresta Vermelha
The Centre of Culture - Spain (in São Paulo) has confirmed that they will be hosting two talks related to our project. These presentations will be focused on the movie "Floresta Vermelha", which is scheduled to go into production in September 2012. Here, members of the production crew will be discussing all the processes involved in shooting an open sourced movie, using Elphel and Apertus technology. These talks will be taking place on 28th June and 12th July, both at 7:30 p.m. (local time). More information can be found at www.florestavermelha.org (website is in Portuguese).
Digital Cinema Guide for the Elphel Apertus System
Project member flavio has been busy writing an article that will be called "A somewhat comprehensible guide to using Elphel as a Digital Cinema camera". It’s not finished yet, but here’s a screenshot taken from the final document (displaying Bits Per Pixel with different JPEG Quality settings). The coloured margins represent different storage systems used throughout the testing of recording parameters on an Elphel 353. Lower values occurred with “live streaming", whilst higher values were obtained without it in place.
Here we can see that External SATA Drives clearly offered the highest image quality (in terms of BPP values) for recording JP46 RAW at a resolution of 2064x896 at 23.994 fps.

Here we can see that External SATA Drives clearly offered the highest image quality (in terms of BPP values) for recording JP46 RAW at a resolution of 2064x896 at 23.994 fps.
“The higher the resolution, the higher the frame size. So another way of looking at the same issue is to consider how much data you need to transfer, both to stream and to record. In my case, my safe margin seems to be:
Maximum data rate (frame size) that can be achieved for 2064×896 @ 23.994 JP4:
Media Frame size with streaming Frame size without streaming
Buggy CF card: 250k ~260k 296k ~ 300k
External SATA drive: 470k ~ 500k 664k ~ 760k
This way I can play with resolution – increase the frame size and decrease JPEG Quality. As long as I keep close to these values, it should work and I shan’t have buffer overruns and dropped frames.”
