# Social Media Pack **Re-render a hero image into Instagram, TikTok, YouTube-shorts and Twitter/X aspect ratios.** ## Inputs | Name | Type | Required | Default | Description | |:---|:---|:---|:---|:---| | `source_image` | image_url | yes | — | URL of the hero image (or asset_id from this session). | | `caption_idea` | text | no | — | Optional caption / overlay direction (kept short). | | `formats` | list | no | 1:1, 9:16, 4:5, 16:9 | Aspect ratios to produce. | ## Steps Use the plan to fan out one node per format. 1.

(only if caption_idea is non-empty). 2. All formats run in parallel (no inter-node dependencies). 3. Return one asset id per format, labelled with the platform it suits: - 1:1 → Instagram feed - 9:16 → TikTok / IG Reels / YT Shorts - 4:5 → Instagram portrait - 16:9 → Twitter / X / YouTube - 21:9 → cinematic banner ## Notes - Don't generate fresh images — only reframe / re-edit the source. - If the source already matches a format, skip that node and surface the original asset id for it. ## Trigger Keywords `social p...
