FlowBlend Deflickering pipeline from warp's video output cell

This part smooths out the frames by blending the current stylized output frame and previously stylized and warped output frame, where consistent areas are blended linearly, and inconsistent areas are taken from the current stylized output frame only. This smooths non-moving parts and helps reduce trails on moving parts.

batch name you've set in your SaveFrame node, default - ComfyWarp

first_frame:
start video from that frame, default: 0

last_frame:
end video at that frame, default: -1, means use all available frames

render_at_frame:
frame at which to begin rendering video. Plug your FrameDataset total frame number here or specify manually if you want to render video before diffusing all the frames.
