I’ve been trying to find a dependable method for exporting HD video from Processing sketches that contain dynamic data and movement as well as complex 3-dimensional shapes rendered using OpenGL. QuickTime’s screen recording option hogs memory and causes frames to skip, as does does ScreenFlow, my usual go-to for screen recording. The best way I have found so far is to export actual resolution PNG files using “save()” and create an HD video using FFmpeg.

FFmpeg is a very fast video and audio converter that can also grab from a live audio/video sources or create and compress video from multiple still images. It is used from the command line and gives one control of bitrates, codecs, formats, resolution, quality, metadata, and many more options for working with video.

To install FFmpeg with Macports
sudo port install ffmpeg

# view help
ffmpeg -h

# list encoders
ffmpeg -encoders

# list codecs
ffmpeg -codecs

# use format
ffmpeg [global_options] {[input_options] -i ‘input_file’} ... {[output_options] ‘output_file’} ...

# make a movie from matching .png files, write over original, codec = libx264 (H.264), framerate = 30, 1 pass, resolution = 1920×1080, video bitrate = 6Mbits, format = mp4
ffmpeg -y -pattern_type glob -i 'p_*.png' -vcodec libx264 -r 30 -q 100 -pass 1 -s 1920x1080 -vb 6M -threads 0 -f mp4 file.mp4

# convert the video file to Apple ProRes codec for use in Final Cut
ffmpeg -y -i file.mp4 -vcodec prores -vb 6M -r 30 -s 1920x1080 -f mov file.mov

# here’s another example conversion command. this one has a much higher bitrate
ffmpeg -y -i file_01.mp4 -b:v 40M -vcodec libx264 -pass 1 file_02.mp4

For example, using this Processing sketch, you generate the PNG files, and then run the code above on the command line to make this file:

Enjoying all the screenshots of glitches that appeared as I was testing the visualization for the Flashpoint show in D.C. Here is a sample.

Surrounded by images of cross-sectioned buildings and source code excerpts, gallery visitors encounter fragments of Washington, DC architecture—a vaguely familiar roofline or grid of office windows—remixed with data and source code representing the latest housing sales in the area. Constantly changing, the live data streams into the gallery from both local sources (DC short sale listings) and national (federal policy sites), emphasizing the effects of related micro-macro shifts.

Generated with custom software, these fragments echo financial systems and housing market fluctuations. They mirror mortgages repackaged and sold, titles lost in administrative tape, and dreams confused by legal jargon. Like the complex financial systems of the housing market heyday, the software generates an infinite number of arrangements. The complexity of unique and dynamically-created algorithmic outcomes contrasts with the comforting predictability referenced in the exhibition’s title, “Grid, Sequence Me.”

—Joelle Dietrick and Owen Mundy

Joelle and have completed our Packet Switching (Weimer Hall) commission in the College of Journalism and Communications at the University of Florida. Read about the process for this project here.

Joelle Dietrick and I embarked on a new body of work this summer called “Packet Switching.” Inspired by her Sherwin Series images and wall paintings, and my work deconstructing and re-visualizing source code and other data, we’ve created two new software projects, as well as a series of limited edition prints, large photo installations, wall-sized paintings, and animations.

The full statement explains our process and intent clearly:

Packet Switching is an ongoing body of work by Joelle Dietrick and Owen Mundy that visualizes architecture as fragments affected by economic and communications systems.

The title of the series references how contemporary communications systems break digital files into smaller manageable blocks of data called packets. Each packet is then sent through a network, taking the quickest route possible, and reassembled once they reach their destination. One JPG image, for example, might be broken into several packets, each of which may travel a different path through the net, even through different cities, before being recompiled into a copy of the original file.

To reference this common process used in networked systems, we wrote custom software that deconstructs a 3D model’s source code and produces unique fragments. We further remixed these fragments using an original application created in Processing. The resulting images become limited edition prints, large photo installations, wall-sized paintings, and animations.

Our process underscores how incidental fragmentation and automation can streamline markets, but also make them vulnerable to systems failure. The use of architecture specifically points to recent real estate market volatility and considers how communication technology-enabled pursuits of profit margins alters our most basic needs.

The first software, that “deconstructs a 3D model’s source code and produces unique fragments,” is open source and available on Github. Essentially, the PHP software, parses a 3D COLLADA file and exports a set number of geometries, that can then be further broken down and used in an artwork or design.

The second software, which we will release soon, remixes these fragments using Processing. The video below shows an example of the whole process.

Wall painting at “Temporary Home” in Kassel, Germany

While artists-in-residence at Temporary Home, in Kassel, Germany, which coincided with Documenta13, Joelle Dietrick and I completed a wall-sized temporary painting based on the architecture from the Bauhaus School at Dessau and 2012 American color forecasts.

Commission at Weimer Hall at the University of Florida

Joelle and I have also received a commission to complete Packet Switching (Weimer Hall) at the University of Florida College of Journalism and Communications this fall. This will be inkjet on adhesive polyester on a large wall (approx. 177.5 ft. x 20.2 ft.). More details soon.

I’ve been working on a lot of projects this summer using various color palettes. Since my work involves writing programs to use these palettes in different visual outcomes, I keep wishing for an easy way to view and negotiate the lists of colors. So today I wrote a simple app to visualize a list of hexadecimal values and sort them by hue, saturation, and value (HSV). The app can be used here, and the code is open under the MIT License.

Thanks to Alexei Kourbatov for the color format exchange functions.

Early images from a project Joelle and I are working on for an exhibition at DOCUMENTA (13). Generated from Processing…

On many occasions over the past few years I’ve wished I knew of a tool that would allow me to search multiple items in a list in separate Google searches, without copying and pasting and submitting each item over and over and over. For example if I’m in a group exhibition and I want to see what work the other artists do. So, I finally took a few hours and created it. It’s called “list-search” and you can use it here and view the code here.

Taking a trip down memory lane with:

$ sudo port install lynx

has proved to be an unsupported adventure.

Somehow I feel my experience was improved regardless.

I’m collaborating with The Periscope Project (TPP) on version 2 of their “Drone Ready-Made: Fine Military Detritus” project in conjunction with the Drones at Home exhibition at Calit2 (see below). In the gallery and online, an interface I programmed, “The Drone War Did Not Take Place,” tracks a Predator drone shipping container, found on Craigslist and retrofitted by The Periscope Project as a camping apparatus, as TPP members guide it through the city of San Diego.

Their path will take them from UC San Diego, past various defense contractors and government agencies including The Space and Naval Warfare Systems Command (SPAWAR), to finally rest at TPP’s downtown location. By (re)mapping data from my Camp La Jolla Military Park project, the tracking interface reveals the connections between the physicality of TPP’s laborious gesture, and the economic and political ties between the object they push and the sites and corporations where everyone employed is implicated in the destructive impact of a permanent arms economy.

The interface will be made public during the upcoming three-day performance by The Periscope Project. It will display their location in real-time, along with images from their journey, and a twitter feed displaying news and unfiltered dialog (hashtag: #dronebox) as they treck through “the largest concentration of military facilities and defense industries in the world.”(1)

Drones at Home
March 7–September 14, 2012

Drones at Home explores the strange allure of drones and the push for their domestication —by governments, corporations, and everyday citizens.

Phase 1
Opening Reception March 7, 2012 gallery@calit2, 5pm-7pm

Phase 2
Symposium May 11 & 12, 2012 Calit2 Auditorium, 9am-8pm

Phase 3
Opening Reception June 6, 2012 gallery@calit2, 5pm-7pm
Closing Reception September 14, 2012 gallery@calit2, 5pm-7pm

“Home” is understood at multiple scales-at the level of the individual, backyard, community, border region, and homeland. The San Diego region is featured prominently and regional issues are explored as exemplars of global phenomena. The exhibition also departs from any strict interpretation of the form that a drone must take; the project expands on the “unmanned” nature of the drone as symbolic of a larger condition–ecologies where the status of the human is called into question, distributed and embedded in a wider field of shared intelligence.

Drones at Home will be presented in three phases. Phase 1 includes an exhibition; Phase 2 consists of panels and a workshop; and Phase 3, which continues through the summer, will include the creation of new drone projects in collaboration with invited artists and research groups at Calit2. Co-curated by Sheldon Brown, Jordan Crandall, and Ricardo Dominguez, this first phase will feature the work of Matthew Battles, Trevor Paglen, The Periscope Project, Alex Rivera and Angel Nevarez, along with additional work drawn from research in the field.

Matthew Battles is a poet, writer, and co-founder of HiLobrow.com. His forthcoming books include Letter by Letter (W. W. Norton), a sentimental and natural history of writing, and a short story collection, The Sovereignties of Invention (Red Lemonade). He is a research fellow with metaLAB, an academic and creative collaborative devoted to the exploration of technology in the arts and humanities, hosted by Harvard University’s Berkman Center for Internet and Society.

Alex Rivera is a New York based digital media artist and filmmaker. His first feature film, SLEEP DEALER premiered at Sundance 2008, and won two awards, including the Waldo Salt Screenwriting Award. Rivera is a Sundance Fellow and a Rockefeller Fellow. His work, which addresses concerns of the Latino community through a language of humor, satire, and metaphor, has also been screened at The Berlin International Film Festival, New Directors/New Films, The Guggenheim Museum, PBS, Telluride, and other international venues.

Angel Nevarez is an artist, musician, and DJ. He has produced works which investigate contemporary music, dissent, and public fora, and move between the spatial simultaneity of performance and enunciation, reflecting upon the projection of political agency through transmission and song. His interests lie in the formation of mobile, performative, and discursive-based social spaces, along with the re-articulation of communicatory systems within such locales. Nevarez is also a faculty member of MIT’s Art, Culture, and Technology Program.

Trevor Paglen’s work deliberately blurs lines between science, contemporary art, journalism, and other disciplines to construct unfamiliar, yet meticulously researched ways to see and interpret the world around us. Paglen’s visual work has been exhibited at the Metropolitan Museum of Art, New York; The Tate Modern, London; The Walker Arts Center, Minneapolis; The Andy Warhol Museum, Pittsburgh; Institute for Contemporary Art, Philadelphia; The San Francisco Museum of Modern Art; Massachusetts Museum of Contemporary Art, North Adams; the 2008 Taipei Biennial; the Istanbul Biennial 2009, and numerous other solo and group exhibitions.

The Periscope Project is a space and co-operative based in downtown San Diego committed to the transdisciplinary nexus of art, architecture, and regional urban issues. Operating by the efforts of its resident practitioners; Drone Readymade represents the first discreet project (outside of The Periscope Project itself) undertaken collaboratively. The project’s primary authors are James Enos (M.Arch, NSAD, MFA UCSD, Visiting Assistant Professor, FSU), Molly Enos (M.Arch NSAD, AIA), Charles G. Miller (MFA UCSD), Keith Muller, Andrea Ngan, David Kim, Jon Barth, Jason Durr and Jay Ojeda; with key contributions from Jon Zuppan. For Drones at Home, The Periscope Project is collaborating with Owen Mundy (MFA UCSD, Assistant Professor FSU).
