Choose a segment that answers one question, then check that its evidence and necessary conditions survive the cut. Rewrite the opening so a viewer who has never seen the original understands the subject and conclusion, and finish by reviewing the vertical framing, voice, and captions.

For a long video about desk lighting, a useful Short might answer ‘Where should I place the lamp to reduce shadows from my hand?’ instead of compressing the entire product introduction. Keep separate notes for the source segment, missing context, and final review so you can spot changes in meaning during the edit.

## Define the one question the Short will answer

A Short's editing unit is one standalone answer, not a chapter from the original. Write down the source video's main claims, then choose one question the viewer can understand or act on. Name the takeaway as well as the subject so the finished piece has a clear purpose.

Record each candidate segment's start and end times alongside the shot that demonstrates its answer. In the lighting example, the placement explanation and the shadow comparison belong together. Keep an entertaining reaction as a separate candidate if it does not actually demonstrate the answer.

If the question requires several lengthy explanations before the answer makes sense, narrow it. One visible decision criterion fits this editing goal better than rushing through several conclusions. Covering the whole source video and making a standalone Short are different objectives.

## Recover the conditions lost at the cut points

A shorter segment must retain the original claim's conditions. Watch the material immediately before and after your selection to resolve phrases such as ‘in this case’, ‘that method’, and ‘as explained earlier’. Restore any missing subject, cause, or comparison standard with a brief introduction or explanation.

A shot showing fewer shadows after moving a lamp may omit changes to the hand's position or other lighting. Retain comparable before-and-after shots, or explain the comparison's limits. Do not turn a result demonstrated in one setup into a conclusion that applies to every setup.

Use the original speech when it already carries a complete answer; add narration when a connection needs explaining. Narration should restore context, not invent evidence that the footage lacks. If the added explanation becomes longer than the useful segment, reconsider the clip or the question.

## Rebuild the opening and scene order around the answer

The opening should serve the selected question before introducing the original video. Replace a broad line such as ‘Today we will explore desk lighting’ with what is being compared and the result the footage can support. Follow with evidence and necessary conditions, and remove explanations that repeat the same answer.

In AUTOVID's long-form-to-Shorts workflow, users can review and edit the start and end points and script of AI-proposed scenes. Use your written question and conditions as the review standard: check that the proposed segment demonstrates the answer before adjusting its boundaries. The proposed selection still needs your editorial judgment.

For the lamp example, read through the question, the two-position comparison, and its conditions, then describe each scene's job in one sentence. If you reorder shots, compare them with the original to preserve the relationship between action and outcome. A smooth sequence can still change meaning when it combines different moments.

## Review the finished Short without the original

The final review should reflect a viewer who has not seen the source. Watch from beginning to end and identify what is compared, what result is supported, and where it applies. If understanding depends on mentally supplying the original explanation, revise the opening or evidence shots.

Check that the vertical crop keeps the subject and action needed for the answer visible. In the lamp example, the lamp position and hand shadow matter more than a close-up of the presenter. Then listen without the picture to check the explanation, inspect captions for covered details, and confirm that visual changes and speech refer to the same information.

Before publishing, confirm that the source footage, embedded music, and added materials are ones you can use, and compare the title's promise with the actual answer. Attribution does not replace checking permission. Point viewers toward the original only when their next question needs its longer explanation.
