The existing five-second lucianax_turn_00001_.mp4 was reused as segment one. Five new
five-second continuations were generated sequentially, producing a validated 30-second
768×1024, 24 FPS H.264/AAC movie with 720 frames. The final official runner status was DONE.
Each continuation takes frame 119 of the preceding accepted clip as its conditioning image. The rolling adapter generates 121 frames and removes the one conditioning frame, contributing 120 new frames. It retains the official Distilled INT8 8+3 sampling path, x2 upscaler, BF16 diffusion decoder, and pair GPU placement. PromptRelay handles the one-frame context plus 120-frame new action. No character LoRA is inserted into the LTX transformer.

The 25 new seconds required 305.502 seconds of ComfyUI generation, or 12.220 seconds of generation per second of new video. This excludes model digest verification, media validation, gallery archival, assembly, and recovery from the initial audio validation failure. The source clip’s previous generation time is not counted again.
All five boundary checks exceeded 0.96 without color correction. Inspected frames show the requested actions and a continuing beach setting. The framing and facial details drift over the chain; high overlap SSIM measures adjacent boundary reconstruction and is not proof of unchanged identity over the entire 30 seconds.
The first continuation initially failed strict audio-duration validation: picture was exactly 5 seconds, while the temporal crop left 4.972 seconds of audio. Its successful raw generation was recovered from ComfyUI history and reused. The runner now pads/trims each continuation’s audio to five seconds while copying video packets, then publishes and validates it. The final picture is exactly 30 seconds; AAC duration is 30.021333 seconds, within the one-packet tolerance.
The source clip was never regenerated. The pre-publication concatenation uses stream copy. The final gallery publication re-encodes through ComfyUI’s normal SaveVideo path. The original source SHA-256, per-segment hashes, metrics, validation checks, and final gallery identifiers are recorded in continuity-30s.json.
