# Source interval action timing

3000 selected GTA V intervals. Existing 100 labels are reused. New intervals use original source presentation-frame identities and native 20 FPS annotation times. First pass: 8 FPS. Boundary refinement: 20 FPS near proposed edges. Wider brackets receive a full-frame API review.

The preview uses 300 original submitted images per interval, arranged into static WebP sheets. It is a reduced-resolution 20 FPS image sequence. Boundary evidence images retain the resolution submitted to the API. No 15-second MP4 intermediates are exported.

Action times are relative to the selected interval. Source annotation times equal candidate start plus action-relative time. Source MP4 PTS are retained separately in the internal frame provenance. Camera is recorded mouse pixel delta x/y, not camera pose.

Frame resolution is not a guarantee of semantic accuracy. Incomplete, uncertain, long and empty results are retained. Browser review notes do not alter the original API outputs.
