+01 · Challenge

The original algorithm extracted frames from video at a fixed rate per second — producing many redundant and blurred frames that slowed down post-processing.

+02 · Approach

  1. 01Replaced fixed-rate extraction with selection based on several factors
  2. 02Added blurriness analysis for every candidate frame
  3. 03Kept only the best-quality frames

+03 · Result

Only sharp frames, far fewer of them, and post-processing 2–5× faster than with the previous algorithm.
