Three independently ugly bugs that all fed the same log flood:
* Electron's `WebFrameMain.send` writes every "Render frame was disposed"
to stderr via `console.error`. When the worker fans a second
agent-event past a reloading renderer, we produced thousands of
identical lines and stalled the main loop on stderr I/O. Added a
`mainFrame.detached` guard so the send is short-circuited before
Electron's own catch block fires, and installed a targeted filter in
`suppress-warnings.ts` (now actually imported from the entry point)
so the specific `console.error("Error sending from webFrameMain:"…)`
noise never reaches the terminal. Any other payload still surfaces.
* `dispatchAgentMessage` accepted the human-reader sentinel as a wake
target when an agent replied to `__board__` — `wakeAgentIfPossible`
then called `db.getAgent("__board__")`, threw, and the dispatcher
kept repeating on every send. Strip `HUMAN_SENDER_ID` at
`resolveMessageWakeTargets`, and keep a defense-in-depth guard in the
heartbeat so a stray caller (future automation fan-out) cannot
reintroduce the crash.
* Pi's skills loader rejects any SKILL.md whose frontmatter `name`
diverges from its parent directory. The four bundled `my-writing-style`
copies declared `name: writing-style-skill`, so every install emitted
a warning and dropped the skill. They also lived as orphan gitlinks
(mode 160000 without .gitmodules), and the global `*.md` gitignore
hid every other SKILL.md from version control. Fixed the frontmatter
to match the dir, converted the dangling submodules to plain trees,
and allowlisted `builtin-skills/**/*.md` so a fresh clone carries the
catalogue instead of silently losing it.

Rendering Transparent Videos
Remotion can render transparent videos in two ways: as a ProRes video or as a WebM video.
Transparent ProRes
Ideal for when importing into video editing software.
CLI:
npx remotion render --image-format=png --pixel-format=yuva444p10le --codec=prores --prores-profile=4444 MyComp out.mov
Default in Studio (restart Studio after changing):
// remotion.config.ts
import { Config } from "@remotion/cli/config";
Config.setVideoImageFormat("png");
Config.setPixelFormat("yuva444p10le");
Config.setCodec("prores");
Config.setProResProfile("4444");
Setting it as the default export settings for a composition (using calculateMetadata):
import { CalculateMetadataFunction } from "remotion";
const calculateMetadata: CalculateMetadataFunction<Props> = async ({
props,
}) => {
return {
defaultCodec: "prores",
defaultVideoImageFormat: "png",
defaultPixelFormat: "yuva444p10le",
defaultProResProfile: "4444",
};
};
<Composition
id="my-video"
component={MyVideo}
durationInFrames={150}
fps={30}
width={1920}
height={1080}
calculateMetadata={calculateMetadata}
/>;
Transparent WebM (VP9)
Ideal for when playing in a browser.
CLI:
npx remotion render --image-format=png --pixel-format=yuva420p --codec=vp9 MyComp out.webm
Default in Studio (restart Studio after changing):
// remotion.config.ts
import { Config } from "@remotion/cli/config";
Config.setVideoImageFormat("png");
Config.setPixelFormat("yuva420p");
Config.setCodec("vp9");
Setting it as the default export settings for a composition (using calculateMetadata):
import { CalculateMetadataFunction } from "remotion";
const calculateMetadata: CalculateMetadataFunction<Props> = async ({
props,
}) => {
return {
defaultCodec: "vp8",
defaultVideoImageFormat: "png",
defaultPixelFormat: "yuva420p",
};
};
<Composition
id="my-video"
component={MyVideo}
durationInFrames={150}
fps={30}
width={1920}
height={1080}
calculateMetadata={calculateMetadata}
/>;
