Maintain Remotion’s expert listings, portraits, and generated cards, then regenerate the homepage animation with transparency. The workflow covers separate Chrome and Safari video formats and checks that matching assets stay consistent across both homepage consumers.
Maintain Remotion's experts directory and its generated assets. Use when adding, removing, or editing experts; changing experts data or portraits; rendering expert cards; or regenerating the homepage experts animation for Chrome and Safari.
Review the instructions the agent will receive before you install.
Regenerate the homepage experts animation whenever the experts shown by
packages/promo-pages/src/components/experts/experts-data.tsx change. The
ExpertsGraphic composition imports this array directly.
Render a fresh transparent ProRes 4444 master from the current branch. Never convert an existing WebM or MOV.
cd packages/brand
bunx remotion render ExpertsGraphic /tmp/experts-graphic-master.mov \
--codec=prores \
--prores-profile=4444 \
--pixel-format=yuva444p10le \
--image-format=png \
--timeout=120000 \
--overwrite
Verify the master reports prores (4444), a yuva... pixel format, and
1080x1080. Extract an alpha frame and confirm it is not fully opaque.
ffmpeg -i /tmp/experts-graphic-master.mov
ffmpeg -y -i /tmp/experts-graphic-master.mov \
-vf alphaextract -frames:v 1 /tmp/experts-graphic-alpha.png
Encode the transparent 540x540 Chrome WebM.
ffmpeg -y -i /tmp/experts-graphic-master.mov \
-vf scale=540:540 \
-c:v libvpx \
-pix_fmt yuva420p \
-auto-alt-ref 0 \
-an /tmp/experts-graphic.webm
Encode a 540x540 ProRes intermediate and convert it to the Safari HEVC-with-alpha MP4.
ffmpeg -y -i /tmp/experts-graphic-master.mov \
-vf scale=540:540 \
-c:v prores_ks \
-profile:v 4 \
-pix_fmt yuva444p10le \
-an /tmp/experts-graphic-540-prores.mov
avconvert \
--source /tmp/experts-graphic-540-prores.mov \
--preset PresetHEVCHighestQualityWithAlpha \
--output /tmp/experts-graphic.mp4 \
--replace
Copy both outputs to both homepage consumers.
cp /tmp/experts-graphic.webm ../promo-pages/public/img/experts-graphic.webm
cp /tmp/experts-graphic.mp4 ../promo-pages/public/img/experts-graphic.mp4
cp /tmp/experts-graphic.webm ../docs/static/img/experts-graphic.webm
cp /tmp/experts-graphic.mp4 ../docs/static/img/experts-graphic.mp4
Inspect all four files. Each must be 540x540 and 60 seconds long. The Safari
MP4 must report major_brand: mp42, compatible_brands: isommp41mp42,
Video: hevc (Main) (hvc1), and handler_name: Core Media Video. Confirm the
matching docs and promo-pages files have identical checksums.
Do not commit either ProRes MOV. Only commit the two WebM copies and two MP4 copies.
The source of truth is
packages/promo-pages/src/components/experts/experts-data.tsx. Keep portraits in
both packages/docs/static/img/freelancers and
packages/promo-pages/public/img/freelancers, with identical contents.
After adding or changing an expert, render their expert card from packages/docs:
bun render-cards
Verify the expected packages/docs/static/generated/experts-<slug>.png was
rendered rather than reported as already existing.

Add a reported Remotion bug to the bugs API with its affected versions, a short title, and upgrade guidance. Follow the existing entry format and place the new record first so recent bugs appear at the top.
Add a Remotion command-line or configuration option, or convert a hardcoded flag into a shared option definition. Connect parsing, configuration setters, help entries, and generated documentation so the option is consistently available and documented.
Add a new effect to @remotion/effects, including its implementation, package entry points, documentation, interactive demo, and preview images. Follow the package conventions and verify the changes with tests, formatting checks, and builds.
Add a person to the Remotion experts page by placing their portrait, entering their profile and contact links, and generating an expert card image. The instructions specify file locations, profile fields, and how to verify card generation.
Create a new @remotion package within the Remotion monorepo, a repository containing multiple packages. Set up its files, register it across the project, and prepare documentation, usage examples, and build configuration.
Add a new sound effect to @remotion/sfx, from registering the audio file to exporting its URL and documenting its use. The workflow covers playback examples, attribution, navigation entries, waveform generation, and the package build.
