A 16:9 compositor. From Circuit bakes a walkthrough. You can also drop clips on a timeline, stack layers, animate them, and export WebM/MP4, GIF, PNG frames, or a .qvid file.

From Circuit

Dialog: file name, clip order, step-by-step options (matrices, live graph, amplitude column, LOOP collapse, row counts). Empty sections are skipped. Sweep programs bind the Circuit Builder combo selected at click time. sweepstate is the default highlight ket. Math still starts from |00…0⟩.

Clip	Content
Title card	Name, qubit count, depth, top outcomes.
Step by step	Column-by-column math walk. 2×2 factors as a tensor product, wrap after three. Purple playhead on the circuit snapshot.
Circuit snapshot	Still of the builder with a column playhead.
Code	Source listing.
Probability graph	Animated bars of the live distribution.
Outcomes table	Ket and percent rows.
Spreadsheet charts	JPEG of sweep / result charts from the workbook, not a second copy of the circuit image.
Bloch	Spheres for visible qubits.
Summary	Wrap-up stats.

Sweep clips are ordered after Step by step. Rebuild after large layout changes so baked frames stay current.

Timeline and palette

Clips (drag onto the timeline): Clip, Circuit Clip, Graph Clip, Bloch Clip, Table Clip. Tools (drag onto the stage or a clip): Title, Text, Subtitle, Code, Circuit, Graph, Bloch, Table, Stats, Shape, Image.

Drag clips to reorder. Drag edges to trim. Playhead scrubs. Space plays. Layers have hide, lock, bring forward (]), send backward ([). Duplicate with Ctrl+D. From Circuit shortcut: Ctrl+Shift+C. Add clip: Ctrl+Enter. ? opens shortcuts.

Clip transitions: Cut, Fade, Slide Left, Slide Up, Zoom. Layer enter animations: None, Fade In, Slide Up, Slide Left, Scale In, Typewriter.

Export and files
