From 9cfbe11bf1d3b64c733d4ccfe470363389061419 Mon Sep 17 00:00:00 2001 From: Brandon Thomas Date: Sat, 3 Oct 2026 02:43:52 -0400 Subject: [PATCH] Layer > Video Layers: frame stacks + Rasterize Video (parity 618) Layer.video (VideoData: frame surfaces + fps + source); the layer's displayed content is the frame at the timeline playhead, re-synced after any edit/navigation. Commands: New Blank Video Layer, Insert Blank / Duplicate / Delete / Restore Frame, Restore All Frames, Show Altered Video, Rasterize (Layer > Video Layers > Rasterize and Rasterize > Video). Timeline duration grows to fit. 4 tests; engine green, clippy clean, wasm OK. Parity 609 -> 618 (98.9%); FLOOR 613. (File-based footage + Render Video + Video Frames to Layers + .pcraft frame persistence are follow-ups.)
