Define description scope
A clip description may summarize the overall activity or describe a specific interval in detail. State which is required and whether audio content belongs in the text. Define whether the description should mention event order, object changes, participants, or the visible outcome. Asking for detailed captions without a purpose can produce fluent text that misses the actual training signal.
Keep claims grounded
Separate what is visible or audible from inferred intentions and outside knowledge. A person approaching a cabinet is not necessarily searching for a tool. If a description uses source metadata, identify that field separately from the grounded caption. Explain how uncertainty and off-screen events should be handled so reviewers do not fill gaps with plausible narrative that the footage cannot support.
Represent time consistently
A sentence describing an entire clip differs from several timestamped event descriptions. Choose the granularity and allow overlapping events where needed. Keep descriptions connected to the exact video version and interval. Trimming, reordering, or replacing a soundtrack can invalidate text even if the filename stays unchanged. Preserve stable annotation identifiers so revisions can be compared without reconstructing sentence order.
Review origin and quality
Record whether text was written by people, generated automatically, or reviewed through a mixed process. Inspect omissions, invented events, reversed order, and unsupported specificity separately. A pilot should include quiet clips and ambiguous sequences, not only obvious actions. Fiund reviews prospective footage, annotation scope, and project-specific commercial use before discussing a delivery commitment for video-language material.
Review checklist
- Choose summary or interval-level description scope.
- Separate observation from outside information.
- Bind text to exact video versions and intervals.
- Record text origin and review error categories.
