344 clips never reached @lollapalooza on Instagram or TikTok. 108 did. 24 are uncertain. 42 sponsor clips are excluded — those shipped to TikTok for the brands (397M views across 24 posts), but TikTok is matched from one cover frame per post, so this method cannot see them.
Decided by pixels, not filenames: every clip was frame-hashed and compared against
the 87 Instagram videos and 245 TikTok covers that actually posted. A clip counts as published when some
frame matches a posted frame within a Hamming distance of 8 — a threshold set by measuring the 30 clips
already verified as post sources, none of which exceeded 7. The 9–20 band is marked uncertain
rather than counted either way. Day is read from the filename, now including Day1–Day4 and spelled-out weekdays; 34 clips still carry none and show as Unknown rather than being guessed.
