Codec Breeze
Codec Breeze (2009) is a set of four short videos that sit between photograph and film. The title names the effect literally: the small breeze a codec makes. Each work is a still photograph in which only the parts that might be alive have been set moving, not by filming them but by pushing them through a bad compressor.
The mechanism is a mask. Van den Dorpel takes a still photograph, selects the regions that could plausibly be alive — leaves, water, smoke — and runs only those regions through a deliberately low-quality codec. The rest of the frame stays a sharp still. The encoded regions shimmer and wobble from compression interference alone, so the picture reads as a photograph that has somewhere started to breathe. As he puts it in the 2009 conversation with his parents (sources/ingested/codec-breeze-parents-conversation-2009.md): "Most areas in the image are still, but here you can see a bit of movement... you can't really tell anymore if it's a photo that we are looking at or maybe a slow-moving patch of mist."
The source of the effect
The observation came from television. Watching Animal Planet or National Geographic, he noticed that a still shot always stayed sharp, but the moment the camera swept or "a huge school of fish swam past," the image was "too big to pass through the TV cable wire" and broke into blocks. The picture failed because it carried too much information at once. Most viewers read that blockiness as a fault — it points to a problem in the transmission. Van den Dorpel kept it as the subject.
His refinement was to remove the actual motion and keep only the artefact. Instead of a moving image, a still photograph is recorded as video at low quality, so "the image would move just from the interference." He links the result to the everyday experience of online video: on YouTube even a film where nothing happens carries this low-grade movement, so "you don't always know for sure if a still shot is actually still or if it's a filmed still shot." Codec Breeze isolates that uncertainty and makes it the whole work.
The four films
Bushes in a park. This was the film he showed first, and it drew the sharpest disagreement. One parent read the massed bushes as figures — "I thought those were people" — while still not seeing the movement van den Dorpel was pointing to: "I hate to say it, but I don't really see it." Only after leaning closer did the motion register, and even then as weather rather than people: "Oh, yes, now I see it. It really is like mist." The encoded leaves move the way wind or fog would move, which is exactly the ambiguity the work is after — motion with no locatable cause, read first as bodies and then as mist.
The artificial flowers. A plastic flower arrangement — white blooms in a ceramic pot, set on the floor in a bare corner — has its foliage passed through the codec. The point sharpens here: the region selected as possibly alive is the one thing in the frame that was never alive at all, and the compressor animates it anyway. The codec does not detect life; it manufactures the appearance of it wherever the mask is drawn.
Smoke that never clears. Here the encoded region is the smoke, "the only thing that's moving, although it doesn't dissipate." Real smoke thins and disperses; this smoke churns in place forever. It is "already a bit strange," he tells his parents, and "that could generate a certain fascination."
The baptism. This is the film where the concept is most exposed. Van den Dorpel kept the whole photograph still "except for the part that is water," which he ran through the codec, so the frame carries a visible seam between the sharp photographic image and the moving, quantized water. The choice of subject is deliberate: baptism is a rite performed in water, and it is the water that the encoding disturbs. "The spiritual significance of baptism is underscored by the randomness in the codec," he says — "the random layer from the encoding converges with the religious significance of baptism."
Chance given a spiritual reading
The move that ties the four films together is the claim about randomness. The compression artefacts are "essentially random," and van den Dorpel deliberately equates that interference with chance, then gives the chance "a sort of spiritual significance." This is an early, explicit statement of a dialectic the wiki tracks across the practice: chance treated not as noise to be minimised but as a carrier of meaning (→ Randomness and Pattern). The lineage he joins without naming it is the aleatory spirituality of Hans Arp and John Cage: chance as a way past the individual will, the sacred located in what the maker does not decide. Where the later generative work uses a fitness function to give chance a direction, Codec Breeze is simpler and more direct — it aims the randomness at subjects already charged with meaning and lets the two register in one frame.
The baptism film makes that claim concrete and, read against his family, provocative. He kept the whole photograph still except for the water, so the sacrament's own medium becomes the site of the machine's randomness. Yoking baptism to chance crosses the deepest line in the theology he was raised inside: an evangelical reading of the world is providential, its events ordered by a personal God, and chance is the exact name for the absence of that ordering. Codec Breeze sacralises the one thing providence rules out.
The uncertainty about whether the image is a photograph or a video is itself part of the argument. Hayles' flickering signifier — the digital image as unstable, prone to unexpected metamorphosis, never quite settling into a fixed sign (→ 805, Mediation and Archive) — is here made visible and slowed to a crawl. The picture never resolves into either a still or a moving image, and that suspension is the work.
Two spiritualities
The 2009 conversation is not a naive audience. Harm's father is an evangelical Protestant preacher who studied theology, and the son was raised inside that theology; both men read the sacred closely. The disagreement over the work's "spiritual significance" is not expertise against inexperience. It is between two spiritualities that work in different ways.
The father's theology rests on the authority of scripture: its claims are held because scripture asserts them, and baptism means what scripture says it means — covenant, rebirth, the washing of sin — a content that is given, and not the individual's to revise. When he asks "where exactly is the clue?... I have no idea about how I'm supposed to make the link," he is reading for a meaning of that kind: authorised, fixed, placed there to be found. His difficulty is not that he understands too little. It is that a theology answerable to scripture has no warrant for the sacred in chance — nothing in scripture underwrites calling the codec's randomness "spiritual," so the claim does not resolve into anything he can accept.
Harm's spirituality stands on a different footing: non-dogmatic, open to revision, geared by a meditative practice rather than a source of authority. The numinous is not fixed in advance by a text; it is what attention finds — here, in chance, the artefact, the loss of control. He keeps the shape of his father's faith, the word spiritual, the water, the rite of baptism, and holds its content open, letting the randomness of the codec carry it. This is why he can say, without contradiction, that viewers "don't have to know that it's called codec," that fascination comes before understanding: a spirituality grounded in attention rather than doctrine does not need the authorised clue his father reads for. The wiki elsewhere calls this structure — later, and about the generative work — "religious in shape, not in content" (→ Apophatic Theology), dating its clearest statement to Dissociations (2010). The 2009 conversation is the earlier, un-theorised version of it, staged in the father's own baptismal water.
Harm's own answer to the question of being understood runs alongside this. Grasping the concept is "somewhat important," he says, but what matters most is that the piece is "visually engaging, so that people will want to look at it" — a split later pages name as the tension between a work's private legibility and its public surface (→ Process Legibility). The transcript's last line belongs to Harm's mother. It is the father, the theologian, who searches for the clue and cannot find it, and then turns to her — "What about you?" — and she says only "I sense it." Apprehension without a proposition, no scripture behind it: exactly the register the work asks for. The person in the room who reaches it is not the trained theologian but the mother, and her sensing is the nearest the family comes to meeting the work on its own terms.
The 2009 conversation was filmed for Lernert & Sander's project How to Explain It to My Parents, in which artists explain their work to their parents.
