Rendering proof / 2.1

A moving picture.
Inside a terminal.

This is not a browser mock-up and not a GIF made to resemble a terminal. It is a recording of the bundled Cinema demo running in Kitty, with every frame sent by terminaltui's video pipeline.

Real Kitty capture · 24 frames

Cinema running in Kitty on macOS. The moving image is rendered through Kitty's graphics protocol; terminaltui owns the page, transport, navigation and layout. The same block falls back to coloured cells on other terminals. Recording: 3 seconds, 1920×1132, silent. Sintel © Blender Foundation, CC-BY 3.0.

01What you see

One block, two rendering paths.

Kitty + Ghostty

Real pixels. Each prepacked frame is transmitted through the Kitty graphics protocol and anchored to ordinary terminal cells, so it scrolls and clips with the rest of the page.

Everywhere else

Coloured Unicode cells. Apple Terminal, tmux and unknown SSH clients keep the same dimensions and controls; only the image tier changes, so the layout never jumps.

02Run it

The proof ships in the package.

Cinema includes the same 848×352, 60-frame TVF pack shown above. No runtime video decoder is installed: playback reads small JPEG frames from the pack and feeds the existing image renderer.
