Only authored clips suppress descendant stamping, so auto-stamped animated scenes can inline-expand. Hide in-flow timed clips with `display:none` only when they are LEAF clips (no nested timed clips). `display:none` on a container removes its whole subtree, hiding descendants that are still inside their own visibility window — e.g. an in-flow composition root whose effective window clamps to the timeline end would black out a child video that should still show (the hdr-hlg regression). Containers keep `visibility:hidden`, which a visible descendant can override; only leaves leave the flow, which is all the split-overlap case needs. --- packages/core/src/runtime/init.ts | 71 ++++++++---- .../studio-api/helpers/sourceMutation.test.ts | 22 ++++ .../src/studio-api/helpers/sourceMutation.ts | 20 +++- packages/core/src/studio-api/routes/files.ts | 103 +++++++++++++++++- 4 files changed, 194 insertions(+), 22 deletions(-) diff --git a/packages/core/src/runtime/init.ts b/packages/core/src/runtime/init.ts index bdc0e2c3a2..39edf7c60d 100644 --- a/packages/core/src/runtime/init.ts +++ b/packages/core/src/runtime/init.ts @@ -410,23 +410,6 @@ export function initSandboxRuntimeModular(): void { return resolveStartForElement(element, fallback); }; - const findTimedClipAncestor = ( - element: HTMLElement, - rootComp: HTMLElement | null, - ): HTMLElement | null => { - let node = element.parentElement; - while (node) { - // rootComp may be null when no composition is mounted; the walk still - // terminates via `while (node)` — node === null is never true here. - if (node === rootComp) break; - if (node.hasAttribute("data-start")) { - return node; - } - node = node.parentElement; - } - return null; - }; - const isTimedElementVisibleAt = (rawNode: HTMLElement, currentTime: number): boolean => { const tag = rawNode.tagName.toLowerCase(); if (tag === "script" || tag === "style" || tag === "link" || tag === "meta") { @@ -1073,6 +1056,21 @@ export function initSandboxRuntimeModular(): void { const dur = String(rootDuration > 0 ? rootDuration : 1); const seen = new Set(); + // Only an AUTHORED clip (data-start already in the source, captured before + // we stamp anything) should suppress stamping its descendants.
