gallente Posted May 27, 2004 Share Posted May 27, 2004 hey I've been watching the music channels and one some videos I've seen that they change the colour of an object. ok that sounds weird so il give you an example there one ash video where hes playing in a field, and one minute his shirts blue, then its green, then its purple, but without any cuts, so its not a stop and change shirt moment. does anyone understand what im talking about? if so, do you know what program I can get to do stuff like that? any ideas appreciated.

peternewman Posted May 27, 2004 Share Posted May 27, 2004 Hi, I'm only guessing here, but could it be a technique like blue screen/green screen. Also known as chromakeying. He would wear a shirt of a colour that wont show up anywhere else in the frame, then a clever box would on the fly replace the shirt with whatever source it was fed. This can also be done in non real time using computer software. However I have never found any software to do it in real time using a PC, so if you find any I would also be interested. I've got a program called Lumiere Video Studio which can do this with recorded footage. I guess any reasonable video editing software would have that feature.

the kid Posted May 27, 2004 Share Posted May 27, 2004 I would say the blue/green screen method would be the most likley. The non real time would be to time consuming I would have thought, any way isn't this method just editing in the colour each frame so shading each bit as the shirt and body moves. Just seems to be to long. Link to comment Share on other sites More sharing options...
P. Funk Posted May 27, 2004 Share Posted May 27, 2004 I don't know... remmeber that with bluescreening you couldntr actually get it to look realistic... the fake shirt would look 'flat'. I'm pretty sure they do it just by changing shirts... its not that hard... film the same tune 5 times or whatever in different shirts and then switch between them when editing.

peternewman Posted May 27, 2004 Share Posted May 27, 2004 It wouldn't be that time consuming, you just tell the computer what to do and it does it for you. Also it can be more than just a single colour, you could for example put a swirly hippy pattern on the shirt. <snip>any way isn't this method just editing in the colour each frame so shading each bit as the shirt and body moves. Erm yes it is, I'm not sure what you mean by this. I don't know... remmeber that with bluescreening you couldntr actually get it to look realistic... the fake shirt would look 'flat'.

Surely it would look realistic as it wouldn't be all the right colours in the shaded bits, so only some would get recoloured. Yes its nice and easy to change shirts, but it would be near impossible to get the changes to line up correctly, however I haven't seen the video, so I don't know what the cuts are like.

This will be some form of CSO (Colour Seperation Overlay) It's a nice technique that can be used on any defined region of colour. (Doesn't have to be blue or green but they often get used) You would have to use a decent software compositing package to do this. Prices for this are coming down now as processing becomes cheeper. One of the problems is that you need to get the original media onto the computer with as much colour information as possible. We would normaly do this, either directly out of the telecine to hard disk or from D1 or one of the HD formats. If you want to have a go then Discreet's Combustion software is available on their site for download to play with (30 day trial) (Though you need serious processing to play with it, My 2.6G machine falls over) This is a good package to play with as it uses the standard discreet front end (as seen with fire inferno and flame) You can do effects like this in real time. I've seen it on domestic level cards, eg the Matrox Digisuite LE cards running Adobe Premmiere, which costs only a few thousand. James. Link to comment Share on other sites More sharing options...

CSO has moved on a lot since Dr Who. Remember that you will retain all the luminance levels, and decent grading systems allow you to seperate and replace with relative colour so you are not filling with a single flat wash. Alternitavly you can take the original colour of the shirt as a key - feed that into a motion tracked map of a virtual shirt, render it in your tool of choice apply shader, and then use the compositing tool to DVE it back into place, mix it in and then regrade the whole shot to make it blend in. This is where an intigrated compositing and 3D enviroment works well, forexample discreet's 3d studio can import into combustion, Softimage comes with it's own illusion compositing software. etc. etc. James Link to comment Share on other sites More sharing options...
gallente Posted May 27, 2004 Author Share Posted May 27, 2004 oh ok, cheers, where can u get that Lumiere Video Studio from, cos the IMSI website knows nothing about it, even though I keep getting dirrected to it when I do a search. what im talking about, is in the video, it changes everything, the scenary, there clothing, face to look like an andy warhol painting. dont know if that explains it anymore Link to comment Share on other sites More sharing options...
Tomo Posted May 27, 2004 Share Posted May 27, 2004 In that case it's probably a straight morph. Usually done off-line in either a DVE suite or dedicated morphing package.I've played about with some of the effects, but I'm more into 3DS Max than Combustion.

Surely it would just be some kind of basic hue change type effect. As to where to get Lumiere, yes it is/was indeed made by IMSI. I got it from a PC Advisor cover disk, ages ago (Feb 2000). You might still be able to find it at a computer fair or specialist shop. Then again some of the cheap consumer/prosumer software available now is probably just as good, if not better.

Pete McCrea Posted May 27, 2004 Share Posted May 27, 2004 Was gonna mention things such as After Effects, Combustion and Final Cut. They have many and varied ways of selecting an area and altering the colours. It is truly amazing what can be done. Even the modest offering that is Final Cut Express runs on my 550MHz G4 Powerbook, and allows me more than I could ever need..... Link to comment Share on other sites More sharing options...
computer Posted May 27, 2004 Share Posted May 27, 2004 hmm isn't there a standard life or something similar advert which is in B&W 'xept some of those float rings things which are orange? Link to comment Share on other sites More sharing options...
Big Dave Posted May 28, 2004 Share Posted May 28, 2004 Having just spent the last week engineering Adobe Live!, its something that can easily be done with After Effects and Photoshop/Illustrator. About 5 mouse clicks if I remember correctly. Link to comment Share on other sites More sharing options...
the kid Posted April 8, 2005 Share Posted April 8, 2005 This is all linked in to blue/green screening but has anyone noticed that in recent reports, from what I remember the pope being one, is that the person is highly lit and the background is not. Is this the BBC cutting down on costs by only using a local camera man and not sending out a reporter? Link to comment Share on other sites More sharing options...
