What Happens Second by Second in the Bama Bound Reference Clip? A Python Timeline of Banner, Motion and Sound (Tested)
Checked November 14, 2026 (15:00 CST, UTC+8). I build bamabound.app , which turns one photo of one person into a vertical clip of them holding a red I'M BAMA BOUND banner. The clip measured here is the "Imported field preview" shown on the site. The site labels it "an external reference of the sign clip. Not a result generated by this studio." I only measured it. It isn't re-published here, and…
The Python script measures the Bama Bound reference clip second by second, detailing the banner's position, motion, cuts, and sound. The clip is nine:16 vertical and lasts about eight seconds. The script decodes the clip at 180x320 pixels and calculates three values per frame: banner area (the percentage of pixels that appear crimson, defined by specific ratio thresholds), banner top (the first row where at least 25% of the row is banner-colored), and motion (the mean absolute grey-level change compared to the previous frame).
For sound, the script mixes to mono at the file's sample rate, calculates RMS in dBFS, and identifies the largest steps in loudness. A cut is defined as a frame with motion six times the median motion and a loudness increase. The script uses ffmpeg/ffprobe on the system PATH and NumPy, and outputs the results in seconds, with options to save to a CSV file.
