What an AI filmmaker actually owns is the show bible, not the footage

What happened
- In December 2024, Kavan Cardoza, who works as Kavan the Kid, put a Batman fan film on the internet. He had been writing a detective story, switched the lead to Batman, and cloned the voices of Robert Pattinson and Jeffrey Wright to carry it.
- The Batman fan film became the most-watched thing Cardoza had ever posted. On the fifth day the video was gone, along with every copy across his other accounts. Cardoza said in a video interview that YouTube identified Warner Bros. as the claimant.
- Cardoza set a hard deadline of December 3 and finished the fan film to it. Days later, OpenAI released Sora. He told a panel at the Austin AI Film Festival that March that had he waited, the film would have been dead on arrival.
- Cardoza makes The Chronicles of Bone, a dark fantasy series he writes, generates, edits, scores and sound designs largely alone, at roughly one episode a month.
- Cardoza said the US Copyright Office has registered his scripts and show bible and approved the copyrights on his character designs. The title is trademarked.

Why it matters
In December 2024, Kavan Cardoza, who works as Kavan the Kid, posted a Batman fan film built from a detective script whose lead he swapped out, carried by cloned voices of Robert Pattinson and Jeffrey Wright [1]. It became the most-watched thing he had ever posted, and on the fifth day it was gone along with every copy on his other accounts, with YouTube identifying Warner Bros. as the claimant, according to Cardoza [2].
The lesson he drew was not about generation speed, though speed was part of it. He had set a hard deadline of December 3 and hit it; days later OpenAI released Sora, and he told a panel at the Austin AI Film Festival that March that a later release would have been dead on arrival [3]. Novelty was the only asset that film had, and it was not his.
His own series, The Chronicles of Bone, is structured the other way around. Cardoza writes, generates, edits, scores and sound designs it largely alone at roughly one episode a month [4]. He said the US Copyright Office has registered his scripts and show bible and approved the copyrights on his character designs, and that the title is trademarked [5]. That is the ownable layer, and he builds it deliberately, working backward from what he believes the Office will accept: "I'm able to copyright my character designs because they start as real photos" [6].
The practice is unglamorous. Before the Collector appeared onscreen, Cardoza bought bandages at CVS, wrapped his own face, put on a black circular hat and a cut-down yellow raincoat, and photographed himself; he calls those images the "Temu versions" [7]. Captain Nemo's mask started as a physical object made by an artist in Spain, which Cardoza bought before sending the maker a contract and taking the rights transfer [8]. Other figures come from public-domain versions of Robin Hood, Captain Hook, Peter Pan, King Arthur and Tinker Bell, chosen for rights reasons as much as creative ones [9].
What remains unsettled is the output itself. Several applications on finished episodes are pending, and Cardoza said he is submitting further evidence of human involvement, including screen recordings of his editing in Premiere, his color grading in DaVinci, and his effects, sound and music work [10]. His position: "I'm pretty confident that when you show enough evidence, you're going to be able to copyright pretty much everything" [11]. That is a bet, not a ruling.
The production economics explain why the scaffolding matters more than the render. In early 2025 the 11-and-a-half-minute The Ghost's Apprentice took 14 days, mostly in Google's Veo [14]. Eighteen months later, a roughly 12-and-a-half-minute battle sequence in Seedance 2.0 took 14 to 16 days at around 90 generations per usable shot, effectively the same rate [15][2]. Then the opening and campfire sequences, about 12 minutes together, took three days in Seedance 2.5, which ByteDance released on July 31 and which Cardoza had early through Magnific's partner program [16][17]. That is close to a fivefold jump in minutes per day [1].
The savings did not stay saved. Seedance 2.5 handles up to 30 seconds per pass and 50 references, useful for 30 recurring characters [18], but Cardoza said it also inserted background music into almost every generation, so he ran clips through Moises to strip it, lost effects in the bleed, and rebuilt that episode's sound by hand [19].
Watch the pending episode registrations. If the Office accepts process evidence as proof of human authorship, the scaffolding strategy becomes a template; if it does not, Cardoza still owns the scripts, bible, designs and mark, and the series carries no advertising anyway [5][20].
