Watch the three center engines on Starship’s upper stage gimbaling just after separation. Right before they ignite for hot-staging, the engines angle themselves outward to direct their exhaust towards the vented interstage before re-centering for ascent.
Both posted on friday, a day before the actual event, with description "20 seconds from a parallel universe where Starship's OFT-2 and hot staging happened today. Best wishes to SpaceX for the upcoming Orbital Flight Test 2!".
EDIT: I was wrong, the link points to a video posted by SpaceX themselves; it's real footage, not a render, after all.
Very spectacular, but unfortunately a render rather than real footage.
Are you sure? The render you link to doesn't have the same engine gimbaling behavior seen in the SpaceX video. The brightness and shape of the hot staging plume is different as well.
