But you can hear the sounds I mean be triggered starting at about 5:00 as he hits the midi-zylophone thing, then the sound is triggered again at 5:08 when he clearly didn't play them and a few times after that. Perhaps what I'm hearing isn't supposed to be percussion and is just the backup music synching with the percussion....but there are definitely kettle drum and other percussion sounds happening when he isn't hitting any drum.

As an artist I can totally see the value in creating new song styles by using comp lyrics. It is just that bad decisions are made when trying to perform said songs live. They need to work out new versions of the song for live performances and not just wing it by deleting words or lip synching.

Here in Norway we run synchronously together with Sweden and Finland, but not together with the rest of Europe. So, we're fine too.

Side note: Currently at work trying to fix a clusterf**k of servers with a proprietary time synch solution not working properly...

Cheers for that. I decided to double my sifting efficiency and watched https://videosift.com/video/Drone-Flight-of-the-Year to that soundtrack... they synched up like Wizard of Oz and Dark Side of the Moon... and I'm not even high! (I started the drone flight after about 50 seconds if you want to try it yourself).

Off to listen to some Joe Satriani now that I'm in the mood for real guitar.

A sneak peek of the future of Fake News: Lip Synching has been added as a related post - related requested by bareboards2 on that post.

Heeeeeyyyy, I was just singing some 4 Non Blondes at my fence the other day. Does that count? Can I make a video of me lip synching in my backyard, feeling a little... peculiar with my fence?

My adorable fence...

"Internet lip-synching perfected"
No truer words have ever been typed.

I completely agree (although Mouth For War is blocked for me). I do think her cover of Roots Bloody Roots would have been vastly improved if she'd lip synched to it.

The audio is just good mixing. He probably used a half moon array of 4 mics and spread out the sound stage. The room looks like it has no acoustics in itself. After the audio is done they just played the performance a couple times getting many different angles, and then synched it with the main audio track.

Music video making 101.

That was great! It sounded like Tom Cruise was actually singing along rather than lip synching--I thought I could hear his voice getting picked up by the mics occasionally when he got close to the cameras.

From my investigation, that's incorrect.
The places in China where hand pollination is used still have bees. The reason they do hand pollination is they switched to a very few varieties of apples and pears...and apple and pear trees need a DIFFERENT apple or pear tree to pollinate, so if you only have one apple variety (the norm there) it won't self pollinate, no matter how many bees there are. Also, climate change is putting the bee cycles and the tree cycles out of synch, making natural pollination even more difficult or impossible. By hand pollinating, they are able to have less than 10% 'pollination' trees to 90% 'fruiting' trees, and pollinate on the tree's cycle. THAT'S why production was better with hand pollination, not because people could do it better, but humans could target which pollen to use on which flower/tree. Also, commercial beekeepers won't 'lend' (rent) their hives out, or require high payments for them pricing most farmers out, because farmers there still use pesticides that kill bees through the pollination seasons.

Other areas that used to do hand pollination have stopped thanks to education. Now they plant more variety (so the bees/insects/birds CAN pollinate for them) and use less pesticides (that they actually didn't realize would kill bees) and are getting better yields for less money than the Chinese.

EDIT: These 'studies' always seem to ignore the incalculable cost of removing all the natural food pollinated by bees, and the collapse of many food webs caused by the loss of that food base. If people are spending cash to do the pollination work, you can be certain they'll go to great lengths to NOT share that produce with any wildlife.

Also, human hand pollination doesn't work for crops like certain grains and smaller vegetables and nuts, main human food sources. It only works for foods where a single pollinated flower will produce something worth the cost of pollination...grains simply don't, and neither do most vegetables, fruits, or nuts. Only large fruits or vegetables could use this economically. So while you're correct, it CAN be done, doing it across the board would probably quadruple the cost of average foods, if not worse.

WIKI-" If humans were to replace bees as pollinators in the United States, the annual cost would be estimated to be $90,000,000,000.[4]"

A friend of mine lost consciousness while parachuting last summer. He says they synched the gear too tight, which cut off his circulation and he passed out. whether he mannaged to deploy his chute, or it opened on it's own, I'm not sure, he doesn't remember anything after that.
He regained consciousness a while after he hit a house and bounced to the ground.
He's lucky to be alive and is continuing to re-learn how to walk again.

No sir.
It is pre-rendered video (or really series of pre-rendered videos) some of them slightly 'tweaked' in semi-real time, most of them not, but not ever by tracking the dancers in real time, which was the whole point of my original post and the follow ups.
Synching the pre-rendered videos with the pre-recorded music is not 'real time rendering' any effects.
An image you 'tweak' on an ipad with your finger(s) to (poorly) SIMULATE real time effects BASED ON MOTION TRACKING is not at all the same thing as real time rendered projections ON DANCERS BASED ON MOTION TRACKING THE DANCERS AND MORPHING THE IMAGE TO THEIR POSITIONS. (apologies for the 'shouting', but you keep missing the point) I'm sorry that's hard for you to understand or admit.

EDIT: For it to be "real time renderings" it would HAVE to track the dancers...which you admit it does not....so I don't get how/why you want to argue a point you already conceded.

#1 Its not fake.
#2 this is probably one of the first couple of full runs, no one but the home owners even know about it.
#3 It is not actually that difficult. The kits to synchronize these lights have been out for a decade now. In a case like this I would;

a) Get permission to handle everyones lights for the year.
b) Using the same kit, I wouldn't get too fancy, gutter icicles, trees, garage outlines, not much more for each house.
c) only need to make one routine, this routine can then be loaded into all houses with only the need to tweak the strands of lights used in each group.
e) syncing would be no problem with an internet aware kit that synchs its internal clock online.

The place turns into kind of a strobe mess because there are not many types of light groups to alternate between, but that can wait for next year. Great effort.

synch is all over the place
