project for creating 3D TRANSITIONS which can work EXTERNAL

our transitions banck is growing, here is a new release:

everything depends in the ALEX´S SCRIPT, which wasn´t released oficially yet, because still need some work, but soon we will release it.
here is the script as it was BEFORE gvfx started (the blendfile was very different then)

glob.tex.setType('Image') # make text be an image texture
img = Image.Load(glob.VIDEO) # load a movie
img.setSpeed(glob.FPS)
glob.tex.image = img # link the image to the texture
glob.tex.animFrames=glob.Num_Frames
glob.tex.animOffset=glob.Init_Frame #set initial frame

mtl.setTexture(0,glob.tex) #place texture in clipB

here is the BRIDGE TEXTFILE: datos.txt just has 3 lines (this may be a xml file in the future)

-----------------------datos.txt-----------------------
/pepe/pedrito/video1.mov,23,123,
/home/video.avi,100,200,
25,720,576,AVIJPEG,
---------------------------------------------------------

we are talking about make the datos.txt file a XML kind, because the TXT structure was simple and good (to make a START) but if 5 transitions are used you´ll need 5 files, and so... that´s why we will change the stucture a litle bit, but thoose are the fields:

CLIP-A with full path "/pepe/pedrito/video1.mov"
CLIP-A starting frame 23
CLIP-A end FRAME 123
CLIP-B with full path "/home/video.avi"
CLIP-B starting frame 100
CLIP-B end FRAME 200
FPS 25
Frame size 720 X 576
Render format AVIJPEG

he have the script so GVFX is on ITS way.
visit our blog to know more about this and how this works, if you want to implement it in kdenlive, please send a mail and we will help you in any way we can.

hi KDENLIVE people :) I´ve been toying with GVFX, and we will fix some stuff, and improve the script to make more things.
actually, you can use the script with THIS FILE:
http://www.4shared.com/file/37099004/6da752fa/gfvxfiltersblend.html

some EXAMPLES:







and with the same process, use our preseted blender 3D-node-editor-FX, the EXTERNAL NLE (could be KDENLIVe) fills the data in data.txt file, and calls commandline render, and gets a video with the effect.
this method may be a little slow, but editors could EXPAND its functionality using blender.

I hope KDENLIVE decides to embrace it.
