Use Processing and FFmpeg to export HD video

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:

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.”

MutaMorphosis: Examining Networks of Power stream today

Posted on by ow3n

I am an “attractor” for a stream of interest at a conference that is happening this weekend in Prague. There are thought-provoking presentations lined-up. Check it out if you are nearby.

Examining Networks of Power
Attractor: Owen Mundy (US)

Addressing the Future: The Tactics of Uncertainty
Attractor: Claudia Westermann (AT)

MutaMorphosis: Tribute To Uncertainty
Saturday, December 8, 2012
13:30-15:30 | Academy 2

Marc Garrett (UK) | Revisiting the Curious World of Art & Hacktivism
Diane Derr (QA) | Morphological Mapping of the Arab Spring through an Ecological Lens
Daphne Dragona (GR) The power of counterpower
Katerina Karoussos (UK) | LUMEN HILARE – The (bio)photonic emission of a church and its metabolism in human consciousness

Owen Mundy: This thread intends to examine representations of contemporary control structures and discuss whether or not an image, particularly network graphs depicting power relationships, information flows, economic activity, etc. have the ability to reverse trends of concentrated power. Does depicting power lead to greater democratization of said power or are we merely creating beautiful images that detract from their original intent—to reveal, examine, and act. To what effect does mapping complex data depicting influential actors, institutions, moments in time, finance systems, mapped onto a two-dimensional surface unravel the power they represent by distributing that power? Methodology: We’ll begin the discussion by looking at historical examples of communication that intend to affect power structures. We’ll examine works by artists and cultural practitioners such as Hans Haacke, Mark Lombardi, Josh On (theyrule.net), Bureau d’études, and more. We’ll consider Manual Castells‘ “Network Theory of Power” within these context(s). Then we’ll discuss visual components of network graphs, asking in particular; what data and
representational forms help make a graph speak to as many people as possible. Finally we’ll work in groups to extend the discussion into possible solutions and various statements and recommendations for such representations.

Claudia Westermann: More than 30 years ago, Michel de Certeau suggested that a shift in methodologies was necessary from strategies that operate on the basis of planning and prediction to tactics that operate on the basis of appropriation. Within this context, competition for the best prediction is substituted for a search for authorities that create the places that give space. This stream of interest with the title ‘Addressing the Future – The Tactics of Uncertainty’ suggests that even though Utopia has not been valued recently, it is nevertheless the actual turn towards the future – this radical uncertainty – that allows for a profound re- questioning of our methodologies. How do the sciences and the arts address the future? Can we speak to it, and in doing so, can we create openings in the present? Methodology: The main intention of this suggested stream of interest is to provide for a ‘good’ start question from which the theme of uncertainty could be addressed in a rather radical way. I am interested in viewpoints from all areas of the sciences and arts. In addition to presentations, there could be conversational panels and workshops. The latter could also be contextualized within the city of Prague. Which inclination this theme takes also depends on the other streams of interest and should be discussed.

CulturalDC Presents
Joelle Dietrick & Owen Mundy: Grid, Sequence Me

Flashpoint Gallery
916 G Street, NW, Washington, DC 20001
01.05.13 – 02.02.13
Opening: 01.05.13, SAT, 6 – 8pm

WASHINGTON, DC – Florida-based art team Joelle Dietrick and Owen Mundy will transform Flashpoint Gallery with an installation of projected animations called Grid, Sequence Me, opening on January 5. Surrounded by images of cross-sectioned buildings and source code excerpts, gallery visitors will encounter fragments of Washington, DC architecture—a vaguely familiar roofline or grid of office windows—remixed with phrases spidered from housing-related websites. Constantly changing, the data will be streamed live into the gallery from both local sources (DC short sale listings) and national (federal policy sites). The inclusion of both local and national data will emphasize the effects of related micro-macro shifts.

Generated by custom software designed by the artists, these fragments will echo the financial systems that led to recent housing market declines. 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 is specifically written to generate an infinite number of arrangements. The complexity of constantly changing outcomes, never repeated, stands in stark contrast to the exhibition’s title, Grid, Sequence Me. We implement grids hoping for comforting, predictable results, even in areas of life—like living arrangements and job creation—that are filled with human folly.

The exhibition offers a space where a visitor can consider how automated, often unseen technological communications and economic systems affect our daily lives and basic human needs.

There will be an artist talk and preview on Saturday, January 5 at 5pm as a part of our membership program. Others are invited to join us. RSVP to gallery@culturaldc.org to attend the artist talk. The public reception will follow immediately after the talk from 6-8pm.

Packet Switching project: ColladaFragmenter software, Kassel, Germany and University of Florida Public Commission

Posted on by ow3n

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.
