You haven't read the beginning of the post, do you?
Well, perhaps my English is rusty enough to be difficult to understand (It
wouldn't be the first time).
Yes, I used Kdenlive for my first published video and it was very good, but
Vokoscreen had problems with the amount of FPS and I had to switch to another
video recorder: RecordMyDesktop. Unfortunately, that piece of software only
records in ogv and Kdenlive and Openshot do not work well in editing videos
with that format (at least, the versions included in Trisquel's repos do
not).
I have to thank you because I didn't considered Blender to do my video. I
don't know if it can work with ogv though but I will record on avi from now
on.
