You know what? Ghosts live in the real world. I've been working with field sequential anaglyphs, which is the exact same format as field sequential 3D for shutterglasses, with the exception that the lines are red and cyan. I am getting the _exact_ same ghosting with anaglyph glasses as you get with shutterglasses and field sequential videos! This sort of ruins the theory that "shutterglasses cause ghosting"... People who view anaglyphs a lot, tend to say, "the glasses are causing the ghosting." Many reasons are given, usually a "leaking" lens. But, since I can't _entirely_ get rid of anaglyph ghosting, no matter what I try, it can't be "the glasses" in this case, either! Look around. Can you see the ghosts, now? See... it _wasn't_ the glasses, after all :-) P. K. Kid Stereoscopic 3D video clips for TV or computer: (Non-commercial, G-Rated) http://www.PuppetKites.net | ||

I've tried your anaglyph page-flipping sollution of a television using video-out on my graphiccard. the problem is I'm having a lot of ghosting, maybe collors are wrong but on a computer monitor or lcd p[anel it looks awesome but on television it just sucks big time because there is too much ghosting, am I using the wrong glasses for tv? on an lcd panel or pc monitor it looks great, I just don't get it why the image is not in 3d on tv.

Only the VLC Media Player will work, and only in the "bob" mode, and only to a 60 Hz interlaced TV. Also, you need a fairly fast computer to do this. The easiest solution might be to burn one to a DVD or SVCD, and play it from a DVD player to a 60 Hz interlaced TV. Basically, most of the *rules*, as far as getting the 3D to work, that apply to field sequential 3D for shutterglasses apply to the field sequential anaglyph for red-blue glasses. I'm trying to update my webpages to tell all this, but meanwhile, I'm still short of material ;-) it's quite a bit more work than I thought to cover all areas of interest... and meanwhile, at the same time, I'm upgrading equipment, internet access, etc, etc... :-) The best thing to do, at this point, might be to convert an existing field sequential video to field sequential anaglyph, using the directions on my "VirtualDub3D" page. You _will_ have to do proper shade corrections, though, or you'll have problems with retinal rivalry... even though the 3D effect will be good when viewed properly. I'll try to get more material uploaded ASAP! Thanks, P. K. Kid Stereoscopic 3D video clips for TV or computer: (Non-commercial, G-Rated) http://www.PuppetKites.net | ||

Also, if you are trying to make a DVD or SVCD, Ulead DVD Movie Factory's MPEG encoder is deinterlacing the *big* video (only one up, still... sorry :-), as is, so you probably have to encode them to compliant DVD/SVCD files, first. This is happening because DVD Movie Factory knows the video is not compliant, and is re-encoding them. (The DVD Movie Factor MPEG encoder is not working for field sequential 3D. Don't even try it!) Your software/hardware may act differently. Compare the results to the screenshots on my download page, by reopening the resulting VOB or MPEG file in VirtualDubMPEG2. The problem I have is obvious... I can't upload a version for every possible viewing scenario, and compliant videos for SVCD and DVD are quite large, and will eat up server space in a hurry. Playing around with video should be a *fun* thing to do, anyway ;-) PKK | ||

And that goes for Nero's MPEG encoder, too. It deinterlaces all field sequential video! Dang! This seems to be a common problem, because in the 2D world, that's what you usually want to happen! Not coincidentally, CRT TV's and computer monitors are rapidly being overtaken by digital formats... Beware! Better make sure your next TV has a "VGA input!" My LCD "TV" has a "VGA in, "S-Video in" and "RGB component in's", and _only_ the "VGA in" from my computer is working for field sequential anaglyphs!!! Who woulda thunk it? ;-) PKK | ||

Okay, I've changed my mind :-) First time _that's_ ever happened ;-) ;-) I have a good solution for SVCD and DVD. I have a "temporary page" of "the most recent" videos that you can burn directly to disc, linked from the main video download page. This way they won't eat up all my disc space, if I just offer the latest two or three this way... And, of course... I still only have one video uploaded... heheee. I'm working as fast as I can!!! Also, I have included a link and a tip for "looping" short segment video experiments on an SVCD or DVD. Here is that page URL: http://borabora.globat.com/~puppetkites.net/tempFSanaglyph.htm I'll try to dig up a second video and get it uploaded, too...! PKK | ||

I just spent a day and a half purposely chasing the "Great White TV Flicker" on this ("Statue Man Time Lapse") video clip. Bright scenes flicker the most, and I knew that if I could tame this one with a re-edit, then any others I try to do in the future can be tamed, too. I looked a few hours for an editing solution, and after trying a few things that didn't work, like "replacing color" and decreasing the brightness and contrast, I think I finally found something that will work. When I watch this one on my TV, now, I can turn down the TV's brightness a little and the contrast a little more, and get the flicker down to the point to where the anaglyph glasses will "filter out" any flicker that's left. What I did to the video clip was put a black background layer behind it, then started decreasing the opacity of the video until the bright parts of the scene lost it's overwhelming glare. I think I ended up at about 75% opacity with this clip. I think it's going to work :-) I've uploaded a field sequential anaglyph MPEG 2 for SVCD and one for DVD, along with the other parallel and field sequential anaglyph versions for dialup and DSL/Cable. http://borabora.globat.com/~puppetkites.net/ My domain name should be transferred to my new server in the next day or two... cross your eyes... erm...

Hi P.K.Kid, I've dl your field sequential anaglyph MPEG2 for SVCD and I've burnt a CD-ROM (ISO9660) with your MPEG2 file (not a SVCD, to be sure NERO will not de-interlace the video ... my stand alone DVD player can read MPEG1/2 files on a standard CD-ROM). Well, the video is fine, the audio too ... but (even wearing R/C glasses) completly FLAT! What can be wrong? Wearing anaglyph spex I can see depth on my monitor ... | ||

Some more info. I've dl from http://borabora.globat.com/~puppetkites.net/tempFSanaglyph.htm the 480x480 video clips and I've got a PAL TV-set. Quite strange: on TV I can't see any "double" image and the colors look right ... like a common 2D video. | ||

I hope I have added enough information to the "instructions page". It reads: >>> Attention non-NTSC TV users! For the following viewing techniques, you might have to do some extra editing to watch these on a TV monitor. Since I use NTSC equipment, you might have to experiment. Use VirtualDubMPEG2 if you need to resize or convert them. 50 Hz PAL TV's will probably cause way too much flicker, and probably require a conversion to 25fps. A "PAL-60" TV might work fine, however. I will not mention this in the instructions, so you are on your own! Any feedback about this would be appreciated! Please email me about what you experience! <<< PAL SVCD's are 480 x 576, at 25fps. PAL DVD's are 720 x 576, at 25fps. Also, if you convert them to that, you are probably going to get way too much flicker. If you have a "PAL-60" TV, I'd like to hear what happens when you try to play the videos I have uploaded. I assume they would work on a PAL-60 TV... but maybe they won't. I'd appreciate some feedback on that :-) I need to go change my website to reflect my recent "Stereoscopic Player discoveries", but by tomorrow or so, I *could* upload a modified version to test, if a PAL-60 video has to be PAL resolution(s) at 60fps... again if you are using a regular 50 Hz PAL TV, it's basically a waste of time to try it, IMO.

Also, Nero Burning Rom won't deinterlace the video, as long as it's a burn to NTSC, and Nero doesn't give you an error message, asking you if it should "re-encode" the video, or something like that. As long as you don't use Nero's MPEG _encoder_, then all is well. A normal burning session won't have to use it. I have only tried this with a complaint SVCD or DVD, so I wouldn't trust an "MPEG 2 playback from a DVD player". Also, be sure your DVD player is not deinterlacing the video, too (like progressive scan does). A standard DVD player with a compliant SVCD or DVD should work, if played on a 60 Hz TV that can show an NTSC video. HTH! PKK | ||

Yes ... I've read something like this. Ok, you' re right: PAL-50 doesn't work BUT THERE NO FLICKER AT ALL and this is strange, just a flat video ... I couldn't expect this! Well, I'm trusting MPEG2 playback from a DVD player but why it shouldn't work? I'm working in non-progressive mode and there's no reason why the DVD player should de-interlace driving a TV-set ... | ||

Okay, if you are using a (standard) PAL-50 TV, then playing my MPEG's won't work, because they are 30fps (actually 20.97fps), not 25fps. So you'd have to change the frame rate to play them. From what I have heard, _that_ will cause way too much flicker. My #2 clip, the "Statue Man Time Lapse", was an experiment on my part to get the flicker of an "overly bright" 30fps video down to an "acceptable" level, which I was able to do _just_ to the point that should work for NTSC TV's, so I know that if you change the frame rate of that one to 25, you will really be disappointed. Also, just the frame rate conversion itself (if you even wanted to do it), is a bit tricky and controversial, as there is no perfect way to do it. If you just delete every 5th frame, that creates a "jumpy" video, at best. I have tried to interpolate "motion blur", but I haven't studied the results very much... it's just a theory, at this point... basically mixing progressive with interlaced video... yes, very odd, but I think it works to a degree. Instead of deleting a frame, you simply blend the fields of every fourth and fifth frame :-) If you separate the fields, AviSynth can do this automatically. If you want to see a _good_ demonstration of 25fps field sequential anaglyph video, maybe someone can upload one made with a NuView attachment. The conversion to field sequential anaglyph is very simple, too, or I can help, if needed. PKK | ||

Well, I didn't explain that correctly. If you separate the fields, the 4th and 5th "frames" no longer have fields, so what AviSynth actually does is blend the 4th and 5th frames... not "fields". Also since "separating fields" means different things to different programs, I am talking here about separating them to side-by-side format... or above/below works, too... and you can then change the frame rate in AviSynth by just leaving the frames at half height, and it will still blend them :-) Lastly, you just re-interlace (weave) them. Also, you might have to resample the audio, but any mis-sync probably wouldn't show up in a short segment. Just wanted to get the steps and terminology correct :-) PKK |
