Wow very nice. Is it possbly to upload the transitions to a compressed windows friendly format? This 3D transition stuff fine under windows too. But .tar.gz files might scrae some people off.

GVFX is oriented to work with linux mainly (that´s why i use tar.gz), but I will love to see it in other platforms (blender can take it), I guess you´re rigth.
I will upload in .ZIP format.

Thanks a million for this! I can't wait to use it. I'm very new to blender but with ready to use blend files like this I can just dive in and use it for effects alongside cinelerra for compositing!

Is there a way to tell the blend file what scene to use - with commandline or datos.txt?

Are the videoclips the exact same size as the source - so you can make a cut in your source, render the transition and add it to where you cut it - will that cut be invisible?

I guess at some point the python script should be able to ajust the keys in the animation to the duration of Outpoint-Inpoint of the source(so the speed would change).

Very nice work on the transitions.

the option is:
blender -b gvfx.blend -S 00.00002 -s 128 -e 498 -o //render_# -F PNG -x 1

this renders a png sequence (in gvfx we will use avijpeg or mov) from frame 120 to 498, the scene 00.00002.

datos.txt will pass information on clip A and clipB (frame start and end), and specific render parameters (but the txt structure may change at some point because you will have a file for every transition... and that complicates the NLE, maybe an XML file could contain all the BRIDGE DATA).

the scenes are pal(720x576), but i hope to find a way to use the render as ntsc also, we will find a way (HD will be difficult) and MUST be the same rendersize that clipA and clipB, but if you use 2 different video sizes, does n´t matter, the clips are UV mapped and fill the planes, so... should n´t be a problem

The SCALABLE keyframes, is a MUST, but I haven´t talked to alex about the scrip in this week, but by default must be 100 frames , as a convencional length, but the script should have to select AL keys from 1 to 100 and stretch it. The speed issue, is not important, because that´s what happends in commercial apps.

if you think about SOME FIX LENGTH transitions, we could create some kind of NON-SCALABLE-CATEGORY... in the scene names 50.00000 to 50.99999 range that´s the case fot the "PUNCH IN THE FACE" effect, wich is NOT a transition, and must be applied in this same way, but never scale it to keep timing. Or we could even have another Blendfile for this non-time-scalable effects (and other for the menu-DVD generator, but that still just an idea).

where te whole idea was growing, and you will see how the Open Movie Editor thinks about it.
I will publish a PDF file with some "basic" data about how to make or modify transitions, with all the conventions that i´m using.
