What the most-liked Claude motion graphics have in common

• Sample: the 63 motion graphics videos about or made with Claude Opus 5.5 posted on X from September 23 to 27, 2026 (UTC, plus two posts late on September 22) that passed 100 likes, from our launch-week library. Likes, views, reposts and replies are X's public counts read on September 28, 2026, so later posts had less time to collect likes. Two posts show very few views for their likes; dropping them moves the median like rate from 0.95% to 0.93%.
• Cuts: ffmpeg scene detection at 30 fps and 320 px wide, a cut when the scene score is at least 0.30, detections under 0.3 seconds apart merged. The threshold was calibrated by eye on contact sheets of six videos: it counts hard cuts and full-frame flashes, and mostly ignores morphs, dissolves, word swaps on a static background and split-screen panel swaps. Cut counts are therefore conservative; 21% of videos have no hard cut at all. Two long posts are measured on their first 175 seconds.
• Color: frames sampled twice a second at 96 px, k-means with five clusters in CIELAB. Motion is the mean absolute difference between greyscale frames at 10 fps. Loudness is EBU R128 integrated loudness (median -14.2 LUFS). Voice was detected with a speech-recognition model plus voice activity detection on the first 90 seconds (at least 12 words and 4 seconds of speech); two videos whose only vocals are a song were set to music by hand. "Opens on text" was checked by eye on four frames per video.
• Statistics: Spearman correlations with bootstrap 95% intervals; group comparisons with permutation tests and Benjamini-Hochberg corrected q values. With 63 videos, a single video can move a group median, and groups under five videos are not compared. Every video here was already a hit, so the study compares hits with bigger hits and says nothing about what separates a hit from a video nobody saw. Follower counts are not in the data.
• Titles, formats and "made with" are editorial labels from the gallery.
