Is it possible to converst anaglyph movies into other formats, like side by side, to be played with dual projection? | ||

That will create a pair of grayscale images. You can also convert a color anaglyph to a "color pair", but let me explain: First of all, no matter what kind of conversion you do to the anaglyph (grayscale or color), if the original anaglyph was created in the "traditional way", which is most likely, you are going to see some shade differences in the left and right images, and this will sometimes be severe. This is because only the red channel was used from the original left image and only the green and blue channels from the right image. IOW, some colors were actually _deleted_ when the original anaglyph was created and you cannot get the shade characteristics back from those colors once they are deleted. If the original anaglyph happened to be created with a "shade-corrective" method, such as an "Optimized" anaglyph or my method, for example, then you won't have this problem hardly at all. Now, a proper conversion from color anaglyph to a color pair results in a monochromatic left image and a cyan right image, but if you carefully tweak the color of the left image, you will see a minimal amount (if any) of retinal rivalry, and your eyes and brain will *fuse* the images back together into a "color image" while you are viewing them stereoscopically. For example, I bet if you page-flip these, you may not even know they are not the same color unless you look at the source images :-) The most important part of this process is getting the left monochromatic color properly adjusted. If you leave it "red" (the right image will be cyan) you will get retinal rivalry that *feels* just like someone is shining a flashlight into your left eye, because the "red" will be too bright. Using VirtualDub freeware, I will show you how to create a color that contains just enough red to "put the red back into the color pair", but not enough to create retinal rivalry: You can find the links to the 3rd party filters on my VirtualDub3D page or I will include the filter links here, too: http://www.puppetkites.net/virtualdub3d.htm In VirtualDub, open the original anaglyph. Apply the "Interlaced RGB" filter: http://www.geocities.com/gc_timsara/vdub.html Under "Even Lines" and "Cancel", check "G" and "B". Under "Odd Lines" and "Cancel", check "R". Apply the "Deinterlace" filter and "Unfold fields side-by-side". Apply the "Resize" filter and double the height (or halve the width) by resampling. Apply the "Hue/Saturation/Intensity" filter: http://neuron2.net/hue.html Check only ("Apply To") "Red". Set "Hue" to "60" and "Intensity" to "1.50". If this doesn't look correct to you, make minor adjustments until it does. P. K. Kid Non-commercial stereoscopic 3D movie clips: (All G-Rated) http://www.puppetkites.net |
