Get an exact multi-layer timing plan, drawing-board frame count, GIF timing, CSV and an SVG sheet. This planning tool uses text only; Xsheet Desk adds source artwork and playback locally.\n\nMethodology:\n- Each line names one column and expands space-, comma- or semicolon-separated drawing references. NxH exposes drawing N for H ticks; zero is blank, and a dot repeats the preceding reference. A hold before the first cell is invalid. Up to four columns and 240 ticks; shorter columns pad with blanks.\n- Composite segments merge adjacent ticks only when every column reference matches. Drawing-board conversion splits runs at ten ticks and must fit 24 frames plus source complexity limits. This planner reports frame count without compiling artwork.\n- GIF segments split at ten seconds. Each delay is rounded(endTick × 100 / FPS) − rounded(startTick × 100 / FPS), in centiseconds. Rounded cumulative boundaries limit total drift; timing remains approximate in players. Xsheet Desk GIF export allows at most 48 segments.\n- CSV is a row-per-tick reference table with formula-prefix escaping for column names. SVG is a timing sheet with escaped labels and no embedded artwork. No audio, camera animation, OpenToonz scene files or drawing generation is involved.", "tags": [ "apps" ], "x-mcp-tool": "flipline_exposure_planner", "requestBody": { "required": true, "content": {
