Verify before you render

Preview any scene graph for cents (no credits) before a full render: POST /api/v1/render/remotion/preview with {"sceneGraph": {...}} responds with { "data": { "frames": [{frame, url}], "issues": [...], "warnings": [...], "diagnostics": {...}, "renderable": bool } }. Default samples land on scene boundaries and midpoints (up to 5); pass "frames": [0, 150, 450] for exact frames. Fix every data.issues entry, re-preview, and only then run the paid render.

For side-by-side or video-over-video edits inside this node, use a split scene (50/50, top/bottom keys) or a composite scene (positioned layers). For one-shot compositing of separately generated clips, use the Video Composite node instead.

Delivery size

By default the render is encoded at high quality, and a grain-heavy 10s 1080x1350 cut comes out around 20 MB. Ad uploads and email attachments want under 8 MB, so set the node's config.output:

• "ad" or "email": the file lands under 8 MB.
• "high", or nothing: today's default quality.
• { "maxSizeMB": 15 }, { "crf": 28 } (1 to 51, higher is smaller, default 18) or { "videoBitrate": "4000k" }, ONE of them, for anything else.

In the Video Editor this is the Delivery select next to Render. A size target is turned into a video bitrate from the render's duration, with 15% kept back for the container and rate-control overshoot and 320k for audio, so it is the duration that limits it: 8 MB holds a watchable cut of up to about 95 seconds. A longer one, or a bad value, fails the run with the reason before anything is rendered, shadow runs included. If the finished file still comes out over its target, the result says so: sizeBytes, overTarget: true and a warning, never a silent success. POST /api/v1/render/remotion/render takes the same output field.

Thumbnail

Every successful run of the node also fills the thumbnail output with a JPG still of the composition, stored on the CDN, so a wire from it reaches an image node without a frame extractor. By default the still is the frame at 10% of the duration, which skips a black intro. Set config.thumbnailFrame to a frame number (from 0, clamped to the last frame), "first" or "middle" to pick another. A bad value fails the run before anything is rendered. The still costs no credits, and if it fails the video is still delivered: thumbnail is left empty and a warning says why.
