Problem
An audio fade designed for the end of a 20-minute video is retained on a 45-second excerpt, making the final sentence disappear under the fade.
Solution
Root Cause / Diagnostic:
Long-form video endings typically employ 3 to 5 second gradual audio fade-outs to ease out credits and end-cards. When a 45-second social excerpt is lifted from the conclusion of a video or when master end-fades are copied onto short-form sequences, a 4-second fade consumes 10% of total clip runtime, swallowing the final call to action or punchline in an unintended fade.
Actionable Fix:
1. Remove all legacy master audio fade keyframes from clips imported into short-form vertical sequences.
2. Implement short, snappy ending transitions: use a 0.2 to 0.5-second logarithmic fade or a natural acoustic tail ending right on the last spoken word.
3. Verify that dialogue audibility remains at 100% nominal loudness until the final 10 frames of the video clip.
Pro Tip:
For short-form looping videos, avoid audio fades entirely; end dialogue cleanly on an upbeat or question to create an irresistible psychological loop back to frame zero.
