Four of the 20 clips (a sentinel, moss macro, a thrift-store try-on and a winged cyclist) had no detector transitions and read as continuous in the sampled frames, while the cut-heavy runs had up to 9.

The scene detector (ffmpeg, threshold 0.30) found no transitions in four of the 20 clips: a near-static sentinel close-up, a macro moss shot with a light change, a vertical thrift-store try-on and a side-tracking cyclist. In H01's sampled frames each of the four reads as continuous. The most cut-heavy runs in the batch were a black-and-white giant scene (9 detector transitions), a 30 s house walkthrough (8) and a security-camera montage (8).

Caution: a detector count is not a visual verdict; soft transitions and cuts between similar frames can be missed, and 12 frames per clip leave gaps.

Reading: continuous framings are what the sampled frames show for subjects with a single repeated action or a held composition; multi-space and multi-camera subjects (a walkthrough, a security system) are the cut-heavy ones.

These are retrospective observations of founder tests, not a benchmark or product validation. Audio was not listened to.
