I've made a small script to move, rotate,scale a strip, directly in the preview area.
The common shortcut are used, G,R,S.
for Each strip you want to modify you need to add a transform effect, select it/them and do what you want.
How to use:
T add a tranform effect to the strip(s)
A select and deselect all strip
Q for the strip opacity (alpha), work with ctrl and value too.
ALT + Q Reinit Alpha.
C : show the crop funtionnalitie, C again close it
grab the corner or the cross to setup the crop.
FOR MOVIE FILE
At the moment, you need to see panel texture and in world texture, you know the small earth.
(A patch come... I hope)
ALT + C: Reinit Crop.
G, R, S grab rotate scale the strip(s)
ALT + G or R or S reinit the values of the strip(s)
CTRL + G or R or S incerment the value.
SHIFT + G or R or S change the value but slower.
X or Y constraint an axis for Grab and Scale only
MMB show axis to choose the axis constraint with MMB
[0..9] [.][-] cahnge the value with numpad.
LMB or RMB (like in user pref) select a strip
SHIFT + LMB or RMB select more strip
ALT + LMB or RMB show a menu to select a strip under the mouse
SHIFT + ALT + LMB or RMB show a menu to select more a strip under the mouse
CTRL + LMB place the cursor2D.
In fact it's almost like in 3D view
I would like to thanks DoubleZ for his help and his great work.
