# Experts ## How to update the videos 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. 1. Render a fresh transparent ProRes 4444 master from the current branch. Never convert an existing WebM or MOV. ```bash 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 ``` 2. Verify the master reports `prores (4444)`, a `yuva...` pixel format, and `1080x1080`. Extract an alpha frame and confirm it is not fully opaque. ```bash 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 ``` 3. Encode the transparent 540x540 Chrome WebM. ```bash 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 ``` 4. Encode a 540x540 ProRes intermediate and convert it to the Safari HEVC-with-alpha MP4. ```bash 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 ``` 5. Use the `offload-r2` skill to upload both outputs under `homepage/` with new versioned keys. Update the URLs in the homepage consumers, including `packages/promo-pages/src/components/homepage/EvaluateRemotion.tsx`. Keep rendered binaries out of both docs and promo-pages. 6. Inspect both uploaded 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 public objects have the same SHA-256 hashes as their local outputs. Do not commit rendered media. Commit the hosted URL changes. ## Expert data 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`: ```bash bun render-cards ``` Verify the expected `https://remotion.media/docs/generated/experts-<slug>.png` was uploaded and is publicly accessible. The command requires R2 credentials from the environment. To replace an existing card, pass `--overwrite=experts-<slug>`. Generated local PNGs are ignored.
