Porphyria | Historical premiere trailer | Subtitled access edition
A historical premiere trailer for Porphyria, approximately 6 minutes 55 seconds, preserving the existing picture, sound and Chinese subtitles. This is a subtitled access edition, not a recording of the full performance. The closing card, “2022/8/27 19:30”, gives historical event information. The work title, duration and closing date correspond to the premiere announcement published on 21 August 2022, but the exact encoding and subtitle version used in the original WeChat publication have not been verified. The platform API reports 6:56, the player page shows 6:55, and the source file has a technical duration of 415.450998 seconds; these measurements remain distinct. The official Archive readback confirms public / processed / succeeded and permits embedding. The background player remained at 0:00, so actual playback has not been verified. This page links to the public YouTube page. The 53-second DJI segment below is a separate source: it is retained without a timing correspondence to this trailer. No verified chapters or additional individual credits are registered.
