Street Dance 3D DVD in UK, but With the Wrong Anaglyph Glasses

October 3rd, 2010 · 17 Comments · Anaglyph Glasses


The movie Street Dance 3D is available in UK with anaglyph 3D version, however they’ve mxed up things a bit as reported by Gareth from Stereo3D.co.uk who bought the movie and discovered with a surprise that the video is encoded for red-green anaglyph glasses, but the bundled pair of paper anaglyph glasses is red-cyan. This comes as quite a surprise, considering the fact that the anaglyph glasses are branded for the movie and are packed inside the DVD, so the mistake is not made by the retailer, but most likely is coming from the DVD packaging company that put the glasses for the movie using the wrong color filters. It may come as a surprise to them but not all 3D is equal, and not all anaglyph 3D is the same – there are multiple formats and solutions and you should be very careful not to mix up things like that, because nobody will be happy when the 3D does not work as it is supposed to. And if the 3D does not work because of such mistake and the user is not aware of where the problem comes from, he might as well get bad opinion about the 3D in general… although anaglyph 3D is not the best form of 3D it is still the most widely usable and affordable at least when you match the right color filter for the glasses with the content encoded with the right anaglyph format. This might be just an issue with the UK 3D anaglyph release of the movie, but the problem might as well be bigger, so if you’ve got the movie and have the same problem please do report it here…

    Is the answer drugs?

    Isn’t it always? (kidding) :)

    Red-Magenta ? :-|
    Probably you meant green-magenta :-D

    However it happens when you are trying to chase the 3D hype of the moment but you don’t even have qualified people to produce and package the DVDs :-D

    I bet many people would not even understand they have the wrong glasses and maybe some of them will even pretend to see 3D images… LOL :-DDDDDD

    Were they trying to win some kind of facepalm award of the year?

    Nothing wrong with that. Gareth sounds like newbe and need to learn about anaglyph technology.

    Gareth also reported on 3dtv that movie was encoded as Magenta/Green. In such case there would be ghosting.

    If the picture included with the article is an accuract screen grab from the disc, it doesn’t look like green/magenta to me. It looks like red/green which should be able to be viewed with red/cyan glasses – although this is not an optimal situation.

    It also seems they are not using pure red and green colour primaries for the encode which are needed to create proper anaglyph 3D.

    Here’s a quick insight into my analysis which reveals something about the encoding used. Splitting the screen grab into separate RGB channels shows that the left perspective image is primarily in the red channel, the right perspective image is primarily in the green channel, and the blue channel has a mix of both channels but is primarily right eye. Thus red/cyan glasses is close, but red/green glasses would achieve the best separation. Green/Magenta glasses work equally poorly as red/cyan (I just tested this) – but would need to be reversed since green/magenta glasses are normally green=left and magenta=right.

    Creating a pair of red/green glasses by borrowing filters from a pair of red/cyan and a pair of green/magenta glasses, does indeed indicate that red/green glasses provide a better result (less crosstalk) than green/magenta or red/cyan glasses – at least for this test image.

    A look at the colour fringing on the “S T R E E T D A N C E” letters in the image also reveals a bit about the anaglyph encoding method used.

    It would be interesting to see some more example frame grabs from this disc.

    In summary, no it’s not green/magenta anaglyph, but yes there does appear to be something majorly wrong. sigh…

    I think that image is just an advertisement for this article, probably created with Photoshop, and not a screenshot from the DVD.

    Red-Green is not a standard encoding and it also achieves worse results than green-magenta or red-cyan so I presume in that DVD they have used the more standard green-magenta encoding.

    If someone has got it please post some real screenshots.

    This is an actual photo of the movie running on a TV with the glasses in front of it, and not an artificial illustration made for the article.

    If it is so then they have really messed it up a lot !!!
    Newbies…

    POSSIBLE SOLUTION…

    I can’t tell you how pleased I am to be reading this.

    This was clearly one of the worst examples of Anaglyth 3D in years so I presumed it was simply put out as sabotage in order to push its release in 3D Blu Ray in near future.

    I felt at the time that it was Trioscopics 3D and tried the specs out but to no real success but I since discovered that it almost works perfectly if you wear the magenta/green or trioscopics specs UPSIDE down, there by reversing the values.

    I feel that this is the next best thing and in fact may well be the correct format.

    Worth a try…

    Same issue on the french DVD version.
    Cyan/Red glasses packed with the DVD and it’s quite impossible to watch the movie without having a serious headache…

  • 13 Bob // Dec 28, 2010 at 20:42

    The same thing happened to me, i brought the film today and it doesnt work with the red/cyan glasses, its all blurry and doesnt show the colours properly. Very dissapointed.

  • 14 Peter // Jan 2, 2011 at 21:39

    Can you take the movie back to the shop for a refund, or can you sue

    So after spending £2,500 on my LG telly, and 200 on a 3d bluray player I discover that the reason it looks shit is because they’ve put the wrong cardboard in the box, and therefore it’s still unwatchable? Great, how I wish I’d found this article a few weeks ago! I’m looking forward to getting some active 3d blu-ray content that exploits hdmi 1.4. Any out there?

  • 16 TJR // Aug 29, 2011 at 18:27

    Bought the film believing that being bluray it would be “proper” 3D (that is for use on an “active” or even “passive” HD 3D display) as anaglyph defeats the point of anything being in HD quite frankly.
    To discover that it’s a complete con that gave me a bloody headache within the first minute just infuriates me. The image for all the above reasons is a psychedelic nightmare! I am making a formal complaint to both the producers and the bluray/packaging manufacturers.

    Hey, so excited to buy the Street Dance 3d dvd, but so disappointed that it didnt work right. After research realised that there wasnt something wrong with me. Is someone going to make up for the trouble …
