Make your own video transition with cinelerra and inkscape // Linux
As you can see, Cinelerra is very useful, but seems to have relatively
poor video transitions. But maybe not... In my life, I have discovered
that OpenSource has no limits. Ready to prepare a new recipe? Let's go!
(If you don't know much about cinelerra, read this first: Cinelerra is very easy)
As you know, Cinelerra can use shapewipe transitions. Shapewipe uses any black and white '.png' format images to make the transition. For example, this image:
...does this sequence
does that mean? Line by line, black to white colors will change from
clip "A" to clip "B". On Cinelerra, you can change the direction that
you want it to animate in:
the 'Browse' button you can choose an image to use as a transition.
Finally, if you want to make your own transitions, follow these steps:
- in a terminal: sudo chmod -R 777 /usr/lib/cinelerra/shapewipe
- if you do not have inkscape install it ( on ubuntu: sudo apt-get install inkscape and open inkscape )
- file > new > Pal_720x576 (or ntsc locale code for U.S. )
- on file Document properties, change Background from transparency to white (ffffffff) - make a black box
-make black text
-files > export bitmap > pages, and save as /usr/lib/cinelerra/shapewipe/mytransition.png
-open cinelerra and add a transition with shape wipe between the two clips
-show shapewipe transitions proprieties, and choose /usr/lib/cinelerra/shapewipe/mytransition.png -change shapewipe direction to "black to white"
