The final festive seconds of the wedding video show a man in his 30s, with a beard and skullcap, swaying gently to the music, tenderly holding his curly-haired baby daughter in his arms.
In front of him, a woman in a silky blue dress dances more energetically, lifting both hands to flick her long dark brown hair behind her ears. And as she does so, without the slightest warning, the floor below these dancers and hundreds of others simply falls away, sending them plunging out of sight, many of them to their deaths, in a great cloud of falling concrete.
The camera keeps filming, now showing a gaping hole the size of a swimming pool, and a handful of utterly devastated relatives, gazing into the abyss and running around aimlessly, screaming wordlessly and unable to comprehend that their loved ones have vanished from right before their eyes.
The text of the invitation to the wedding of Mr Assaf Sror and Ms Keren Yosef promised guests "a very special event".
In the words of the Israeli Prime Minister, Mr Ariel Sharon, yesterday, it became "a national disaster . . . one of the gravest Israel has ever known."
Rescue teams worked through a second night, terrified that the roof of the building might fall in on them, and racing against time in the fading hope of digging survivors out of the wreckage of what was once the Versailles Hall.
Police put the official death toll at 23, but warned that it would climb higher: 10, 15, perhaps even more people were still said to be unaccounted for, and many of them might prove to be buried beneath the slabs of fallen concrete. Nobody had been brought out alive since yesterday at 2 a.m.
Mr Sharon said he was considering ordering a state commission of inquiry into the disaster, but already there are compelling suspicions of criminal negligence. Police yesterday called in no fewer than 10 people for questioning under caution, including the various owners of the five-storey building in which the Versailles Hall occupied the top floor, and several contractors and engineers involved in both its original construction and more recent renovation work.
It is alleged that the owners ordered support pillars or even a supporting wall removed from lower floors of the building, to afford greater open space for events held there - an act described by the bride's father as being "as viciously criminal as detonating a bomb there". Also among those questioned was Mr Eli Ron, inventor of the "PalCal" material used in the construction of floors and ceiling in the building. Once hailed as a cheap and revolutionary building material, "Pal-Cal" has long been branded unsafe by Israeli building standards institutions but is still widely used.
Of the 650 guests at the wedding, more than 300 were injured in the Thursday night disaster, and more than 170 - including the bride (who is seriously injured) and groom - were still in hospital last night. Throughout the day, news was being delivered to those in hospital that the body of this or that relative had been pulled out of the rubble. Among the dead were a three-year-old child, and the groom's grandfather and uncle.
Mr Shaik Kinsan, one of those relatively lightly injured, spoke from his hospital bed about the fact that, "since my best friend was killed on bus 18 [the Hamas suicide bombing of a bus in Jerusalem five years ago], I've tried to be so careful about everything I do, everywhere I go. But apparently you can't escape. It chases you. It's not enough that we have the trouble with "the cousins'," he said, tailing off into silence - "the cousins" being a dry reference to the Palestinians.
