What was measured

Animation quality

The smoothness and visual polish of word-level transitions, highlight effects, and synced emoji or sound effects.

What was given, what came back

Test input: AI demos chatbot short · video

Input — what we sent

Input file 1 — as supplied

Input file 2 — as supplied

Fast-speaking single-speaker clip used to stress whether visual word-by-word highlighting stays synchronized with rapid audio.

Why this input is hard

· high-speed audio-visual sync
· caption timing under rapid speech
· sync drift detection
· highlight lag during fast delivery

Output — unretouched

Also checked on this input — same tool, 2 other criteria

Style range◐ MixedThe report exposes predefined styles, but describes them as standard corporate subtitles rather than a broad set of sharply distinct presets, suggesting a narrow style range.Timing precision✓ WorkedWord-level caption highlighting stayed locked to rapid speech, with the report saying it maintained high accuracy and showed no sync drift during fast syllables.

AutoCaption.io✓ WorkedThe kinetic word-bounce preset tracked rapid delivery smoothly without visible frame delays or caption overlaps.Opus Clip⚠ StruggledThe highlight animation is not fully smooth under speed stress; the report describes minor frame drops and visible stuttering rather than polished continuous motion.
