Re: stereoscopy

hi,


no i am not talking about guessing an images z-depth on certain areas which i know would be far to complicated and impossible without a tool like blender. what i talk about is combining two matching videotracks to one stereoscopic video track. you should be able to choose what kind of colours your 3D-glases have and stuff like that. so we need a set of tools that makes editing/creating and rendering 3D-movies easier. well i don't think that we need to have support for polarized (linear and circular) projection methods since thos projectors are far to expensive and the amount of needed storage is far to much.

when it comes to coding i would try to clone the source repo of cinelerra, but then i could need a helping hand to get a grip on the code. so is it even possible to start working on those features in the state lumiera is right now?

greets

A few typos in the last email:


While not a 3D expert, it doesn't exactly work that way.

 3D video shot with parralax (the current technique) would have to lined up and synched, which would be a playback issue. But what you're talking about is a 3D compositing function, which would involve "making up" 3D information rather than playing back parralax/stereoscopic 3D video and editing it.

Extrapolating depth from an image in an attempt to create a 3D composite is very tricky business. Using two alternating/polarized 3D images to give a 2D version of a shot to each eye is very different. But it's a cool idea nonetheless.

hi,

i thought about some kind of a filter or mixing-effect. so for example you put the two video-tracks in sync above each other and then you apply some kind of stereo-mix-mode and you are done. this would also allow more flexibility since you still can edit both tracks with all the other filters and effects available in lumiera.

so can this be done and does anybody wants it to be done?

sincerely seb
