Flicker-free Stable Diffusion video, held together with glue

What it does

TemporalKit is an AUTOMATIC1111 extension that preprocesses video into keyframe plates, runs them through img2img, then hands the results to EbSynth for interpolation. It essentially orchestrates a multi-tool pipeline—FFmpeg for frame extraction, Stable Diffusion for stylization, and EbSynth for motion-aware frame synthesis—so you don’t have to manage the folder shuffle entirely by hand.

The interesting bit

The clever part is the plate-based batching: it tiles frames into grids so you can process multiple keyframes in a single img2img pass, then leans on EbSynth’s motion-aware synthesis to fill the gaps between stylized frames without the usual AI-video smearing.

Key highlights

• Extension for AUTOMATIC1111 WebUI, not a standalone app
• Splits video into tiled “plates” to batch-process keyframes efficiently
• Relies on external EbSynth and FFmpeg binaries to do the heavy lifting
• Explicitly warns that EbSynth ignores keyframes if sampling steps exceed 20
• Ships with a TODO list that includes API hooks and diffusion-based upscaling

Caveats

• Known dependency conflict with tqdm can prevent WebUI from starting until manually resolved
• The README’s own TODO lists a “weird shutdown error” that still needs fixing
• Requires manual handoff to the external EbSynth desktop application; it does not generate .ebs project files itself

Verdict

Worth a look if you’re already deep in the AUTOMATIC1111 ecosystem and need a structured way to turn SD flicker into motion. Everyone else should probably wait for a more integrated tool.
