At the moment nearly the whole Kdenlive team is hacking in Randa, Switzerland, at the KDE Sprint 2011. Don’t believe it? Here is the proof:
(From left to right, ttill, xzhayon, j-b-m, Granjow.) So, as you can see, we are totally busy coding and writing the manual. The main activities are:
Big refactoring which will improve our code base in terms of maintainability and (for new coders) readability. We created a new branch for the refactoring. When refactoring is complete, we should also be able to write some automated tests.
User manual; we are now definitely moving to KDE Userbase which is based on MediaWiki (you all know this from Wikipedia). It will also simplify translation. The first version of the Quickstart tutorial is already online.
GIT will be our new version control system at KDE multimedia.
That’s it so far! We’ll go back coding now. — Your Kdenlive developers
Several Kdenlive developers will meet in the next days in Randa (which will host a big KDE sprint) to exchange ideas and discuss about Kdenlive's evolution. I hope that we will come up with some great ideas, we will keep you informed!
So … this all started when a friend, Melanie, was working on her final paper about Light Graffiti and showed me the video below around mid-September.
Light Painting, also known as Light Graffiti or (partially) Lumasol, is so easy with a photo camera. You take a dark room, use a low shutter speed (several seconds), and paint in the air.
But what about video? You cannot decrease the shutter speed to one frame per minute. Therefore it is not possible.
This really made me think a lot. Actually for several weeks.
After a few minutes of research, I found that the effect used to create the video seems to be kept secret. (At least I couldn’t find any technical information about it.) After some additional research, I read that they actually did this effect in hardware (i.e. programming some camera chip) — but this was after I’d already written this blog post. (Actually, I’m not sure whether it is truely in hardware; some effects suggest that it was done in post as well, like in the part where you only see the light but not the painter.)
Nevertheless, the idea was fascinating, so I decided to start writing an effect frei0r filter that would do the same. It couldn’t be that hard.
In the next version of kdenlive you will again find new scopes. This time not for video but for audio! I will also give some tips about audio in general (recording, perception, etc.), not only about kdenlive’s scopes.
