Hello: I am using Stereo Movie Maker to join left/right video segments into a field-sequential 3D movie. I have noticed, however, that I get a lot more ghosting with stereo movie maker (even though both images are clean). I am not sure what might cause this....there is a setting in another video editing program within my overall process that MAY have something to do with it: There is a setting for "interleave every ___ seconds"...it is defaulted to 0.25 s, so I am wondering if anyone knows if perhaps this number is too large or too small, or what effect, if any, this setting has on the final interlaced 3D image once the resulting files are input and combined with Stereo Movie Maker? | ||

The "interleave every ..." in most standard editing programs refers to the way that the separate AUDIO and VIDEO streams are packetized. It's the "checkerboarding" of those 2 types of streams that it's referring to, NOT about INTERLACING, which should always be constant--either progressive (No interlacing) or interlaced (field interlacing Odd/Even every other), which is often determined by the program source and codec. If that "interleave every ..." number gets way off what is expected, what you'd end up with would be audio or video SKIPS. Ghosting has to do with: #1--your chosen 3d storage and display technology. In this case, field sequential/interleaved, which doesn't have inherent/stored ghosting, but which leads you to... #2--your display subsystem real-world non-linearities. In this case, you're probably using LC shutter glasses (or display) that are not fast enough to completely become extinct before the other image flashes. This is made worse by... #3--too much brightness #4--TOO MUCH disparity between viewpoints (which prevents your brain from fusing the 2 images). What's your original interaxial distance? Are you shooting converged or parallel? Have you done any horizontal adjustment? There's a difference between variations in recorded interaxial and variations in merged/displayed interaxial, and ONE cannot completely fix/counteract the effects of the OTHER (they are perceived differently in the brain). Need more info on your setup... Scott | ||

I am using LC glasses, but some DVDs seem to ghost worse than others, and it seems much worse on video I have processed. To make matters worse, a friend is unable to see 3D even in movies that appear 3D to me--I sent him a DVD recently and all he saw was double images, while other field-sequential DVDs that I did not process--he has no problems with those. The option to interleave or not is within the audio rendering options, so I am thinking this particular option refers to the video specifically, as described here: http://www.mir.com/DMG/interl.html I am now rendering some test clips, but so many variables to play with! Top field/bottom field first, resample frame rate, interleave, etc.... (Message edited by rrrrob on February 05, 2007) |
