So, after putting on my detective hat and going through advanced searches for a while (can you tell it's a Saturday and I'm happy to be at work?) here are the precedents I discovered.

Videos of the exact same event taken from different angles (same audio)

Wind Turbine Self-Destructing
http://www.videosift.com/video/Windmill-Destroyed-By-Wind (original)
http://videosift.com/video/Wind-turbine-self-destructs (potential dupe)

In this case the majority (6-4) barely decided it was not a dupe and it stayed.

Window Adjusts Lighting
http://videosift.com/video/Philips-Daylight-Window-Concept-Presentation (original)
http://www.videosift.com/video/Ambient-window-adjusts-lighting-hue-and-patterns (potential dupe)

In this case, kronosposeidon conceded the extra camera angles added nothing and left it up to Farhad2000 whether to declare it a dupe or not. Farhad apparently graciously decided not to.

Mythbusters paint the Mona Lisa with Paintballs
http://videosift.com/video/MythBusters-CPU-vs-GPU-or-Paintball-Cannons-are-Cool (original)
http://videosift.com/video/Mythbusters-Paint-the-Mona-Lisa-with-Paintballs (potential dupe)

In this case, the original garnered far more votes than the dupe, so there wasn't much controversy. Consensus seems to be that it is a dupe. However, to this day it remains Sifted.

Mentos and Diet Coke Explosion
http://www.videosift.com/video/Record-breaking-Mentos-and-Diet-Coke-Explosions (not sure)
http://videosift.com/video/Mentos-and-Coke-Light-World-Record-Attempt (not sure)

In this case, Maatc and Ant came to an amicable agreement in which they agreed to put links to each others' videos in the descriptions.

Suggestion

Precedent seems to be that the same event captured with different angles but containing the same audio is not a dupe. However, precedent also seems to suggest that most Sifters are gracious to each other and try to spread the votes around fairly. So, maybe each of you could put a link to each others' vids in your description and hopefully people who vote for one will go and vote for the other. Sound fair?

This video has been seconded as a duplicate; transferring votes to the original video and killing this dupe - dupeof seconded with isdupe by chicchorea.

*isdupe>> ^Hybrid:

dupeof=http://videosift.com/video/Wind-turbine-self-destructs

This video has been nominated as a duplicate of this video by Hybrid. If this nomination is seconded with *isdupe, the video will be killed and its votes transferred to the original.

*dupeof=http://videosift.com/video/Wind-turbine-self-destructs

Well, here are two videos of the same event from different angles, which were found not to be dupes:

Video 1
Video 2

However I'm not sure, in this case, if this is really something that needs to be seen from multiple angles. I'd probably call it a dupe.

So this one was struck by an INVISIBLE UFO!

Ha, the irony. you tried to BAN me. so sad to see you're gone.

These types of videos make me kinda sad, the destruction of something so beautiful and useful is a little depressing.

I heard it's a challenge to keep the blade tips on these huge windmills from creating sonic booms.


To check this we can look at the velocity of the tips of a blade, and compare with the speed of sound to see if a sonic boom will occur. According to Wikipedia, common modern wind turbines have a blade radius of 20 to 40 m. Taking an average of 30 m:

velocity = rate of rotation x radius
speed of sound = 343 m/s
radius = 30 m

rate of rotation where the tips are approaching the speed of sound = 109 rpm
This is much greater than the common operating parameter of 10-22 rpm

For the worlds biggest turbine (according to Wikipedia), r = 63 m
rate of rotation where the tips are approaching the speed of sound = 52 rpm

So it does pose a problem for really big turbines, but in general can be avoided for average turbines. Also, note that with any wind speed the required rotation rate will be slightly lower, since the velocity at the tips will be the combination of the wind and the rotating speed.

The more you know!

>> ^gwiz665:
A dupe is a video with the exact same content or less, different angle = different video = not dupe.
arsenault185: In your example there would be no dupe unless the exact same clip was used in both cases. If there is different voiceover, but same video it is also not a dupe.


I don't agree with this definition. And the FAQ doesn't either. Providing new audio does NOT automatically make a submission not a dupe. From the FAQ:

" Duplicates will be * discarded. A duplicate video is one which contains content already on VideoSift in a published, queued, personal queued, or dead video submission. Minor changes in content, like a few additional insignificant seconds of video or alternate background music, will still be considered dupes. The only exception to this is if the change in audio makes a significant difference to the video content."

emphasis mine

It's not a dupe. It's NOT the same video. It was shot from a different angle, with a different a camera. Therefore not a dupe.

Who cares if it's the same event? The rules don't prohibit videos about the same event. They just prohibit the same video. If the rules prohibited the same event being displayed, then if two people submitted videos about Macy's Thanksgiving Day parade, each one shot from different angles, would they be dupes?

Sure, these videos are similar, but not similar enough to call dupe on this one. That's why I had no problem voting for both.

My opinion was requested, so there you have it. Now we have a tie: 3 for and 3 against. Can someone else weigh in to break this tie and end this, please?

>> ^MarineGunrock:
discuss - Exact same event - new camera angle offers nothing new and in fact is worse quality video.


I disagree with you, gunner. This should be *returned. It's not a dupe. It offers a wider vantage point, therefore it adds something new to people like me who would like to see multiple angles of something. Ideally, it would be best if both videos were combined into one, but that's not the case. And for those who would like to see more on a subject, multiple angles is a great way to do so.

In reply to this comment by DavidRaine:
Wind turbines kill birds, and now we see their operation is unsafe and causes wanton destruction to nearby wildlife. We ought to outlaw these dangerous turbines and move to clean, safe, nuclear energy!

I'm not sure if wind turbines can be accurately categorized as causing "wanton destruction", though I will second your notion for nuclear energy (still I'm pretty sure your comment was made in jest). Those fucking baby boomers and their fear mongering back in the '80s has put a damper on new nuclear power plant development in this country. Yet another reason to hate the hippies! Stop fucking in the bushes, cut your hair and get a job, hippies!

It's a shame we don't embrace nuclear power, because it's really a clean and sustainable energy source. A lot better than fossil fuels, in my opinion. I want every car to be equipped with the Flux Capacitor and your very own Mr. Fusion to power it with banana peels and refuse.

>> ^qruel:
I think daivraine was using sarcastic humor as nuclear is not cleaner than wind, nearby wildlife was not killed in these 2 failings (out tens of thousands) and more birds are killed flying into skyscrapers than wind tourbines


This is why I prefer VideoSift to YouTube. Its residents recognize sarcasm.

These types of videos make me kinda sad, the destruction of something so beautiful and useful is a little depressing.
