Frame Chooser

Pauses the running graph and turns the node into a clickable filmstrip of every incoming frame. Pick the frames to keep, press Keep selected, and the graph resumes with just those frames — always in their original order.

Controls

• frames: A BHWC image batch, commonly the frame output of a video loader.
• behavior: always pause stops every run until you answer. keep last selection re-applies this node's previous answer immediately and only pauses when no previous answer fits the current batch.
• preview_max_size: Longest edge of the filmstrip thumbnails. Smaller values encode and load faster; the full-resolution frames are untouched.

While paused

• Click thumbnails to toggle them; the header counts the selection, and ALL / NONE flip the whole filmstrip at once.
• Keep selected resumes with the chosen frames. Keep all resumes with every frame — an empty selection deliberately means keep-all, so a quick "just continue" can never produce an empty batch.
• Cancel (or Escape while the panel is focused) interrupts the run exactly like ComfyUI's stop button. Interrupting the queue also releases the pause.

Outputs

• frames: The kept frames as a BHWC batch, in source order.
• count: How many frames were kept.
• indices: The kept one-based indices, comma-joined (1,4,9).

Thumbnails are written to ComfyUI's temp folder and disappear with its normal cleanup; answers travel over a local /ausboss/frame_chooser route. The last selection is remembered per node id for the current server session only.
