Assemble the per-shot footage in into a finished cut, and write the selections/omissions into . Each segment uses a second-level heading , and is bound to one and one real media file.

Choose usable segments based on the actual footage, and verify the narrative against the script and storyboard. When the footage does not match intent, record the trimming decisions and gaps.

The entry condition is that footage already exists and is readable: the directory must contain the video files to be used this time. A finished prompt, a confirmed job, or a successful adapter response does not mean the footage is usable; this stage only accepts file bytes that can be opened right now.

When footage is incomplete, you may first cut the contiguous segments that already exist; when the user asks for a complete final cut, mark this version as a fragment and list the gaps. In “Unused shots”, state whether the issue is a missing file, unusable quality, or a narrative trim.

and are the sources of shot order and responsibilities. Editing may select/omit them, but may not rewrite them: deleting a shot, shortening a shot, or reordering are all within this stage; changing dialogue, changing a shot's responsibility, or changing start/end states must go back upstream as a revision request.

The built-in renderer concatenates encoded segments directly, so input footage must have the same frame size and frame rate. verifies this when the media is detectable; if specifications differ, first unify them with external tools according to delivery requirements, preserve the composition and record cropping or letterboxing, then update the paths and time ranges in the edit list.

Rendering and measurement require / on the PATH. If they are missing, fails immediately and states the reason; do not approximate with other methods, and do not write “untested” as “passed”.

Commands are provided by edit_tool.py:

python3 <本技能目录>/scripts/edit_tool.py check <剧集/EP001> --project-root <project>
python3 <本技能目录>/scripts/edit_tool.py render <剧集/EP001> --project-root <project> [--no-subtitles] [--subtitles ffmpeg|remotion] [--remotion-concurrency N]
python3 <本技能目录>/scripts/edit_tool.py verify <剧集/EP001> --project-root <project>

verifies only, without rendering: whether the footage is newer than the edit list (after regeneration, subtitle timings must be re-measured), whether ranges are self-consistent, whether references parse, file existence, whether ranges do not exceed the footage length, whether ranges from the same source do not overlap, and whether subtitle text can be found in . Among these, “ranges do not exceed the footage length” requires ; if it is missing, report that item as “untested” and explain why, rather than silently skipping. cuts segments according to the edit list, concatenates, burns subtitles, and normalizes loudness, outputting to . only measures the already rendered final cut and reports numbers; it does not modify files and does not give quality conclusions.

Subtitles are burned by default using ffmpeg with libass. switches to a route with adjustable typography, at the cost of installing Node dependencies once, and the overlay must be rendered frame by frame through a headless browser for the whole final cut—slow and memory-heavy, with concurrency limited to 2 by default ( is adjustable; measure the machine before raising it). See Sound, subtitles, and music for trade-offs, and Remotion subtitle overlay for installation.

keeps the cut intermediate files. It only cuts segments, hard-concatenates, unifies subtitle style, applies splice correction, and normalizes whole-cut loudness; it does not execute the mixing plan in the line, nor does it automatically scale or change frame rate according to delivery specifications. For mixing, per-shot subtitle avoidance, transitions, or frame-size conversion, complete them with external tools and record what was done, then accept the actual delivered file.

First read this SKILL, the current storyboard, video prompts, and footage; when subtitles are involved, read the script original. Open references as needed:

Keep unaffected IDs. Changing one segment's in/out points should not touch other segments; when deleting a segment, state which segment takes over the information it carried, or state explicitly that this information no longer appears in the final cut. Update the edit list before re-rendering; do not let the final cut get ahead of the document.

This stage is complete when every is bound to real footage and a self-consistent range, dialogue is fully audible in the final cut, subtitles are verbatim equal to the script original, there are no audible hard cuts in the sound bed at edit points, the final-cut loudness lands on the delivery target, and all unused shots have their reasons written with the distinction between missing files and missing quality. The difference between target duration and actual duration, and any places still worth another cut, are written in the report at the end for the creator to judge.

Run only when installing, upgrading, or troubleshooting.
