Generated stills always fill Still A again (including Generate and queue restore), and Flux/Krea, MiniMax/LTX, and ACE/YuE sit on the input holder so you pick the engine before the prompt.
Keep every saved segment, show the longest clip with an expand list, branch on extend, and parse shot 2/3 blocks into a shared-duration queue with live part status.
The overall bar made a long queue look stuck at ~9% during the first clip, and nothing was written until the last step. Save checkpoints, use per-step progress, and stop treating a short Comfy history lag as a dropped job.
Purging desktop files let MiniMax reuse MiniMax_H3_00001_, so the next job returned the previous clip. Ignore stale events from the last job so a second generate cannot paste the first video over the new one.
The slider never left this machine, so deploy the generate UI with separate input/output hide toggles, reconnect in-progress jobs after refresh, and delete Comfy input/output files after they are saved to the library.
