Widget layouts in kdenlive

You may probably have noticed that some additional widgets have been added to kdenlive recently. And you probably do not want your kdenlive to look like that:

(Notice that this is on a 1680×1050 screen. You absolutely don't want kdenlive to look like that on an even smaller screen.)

Writing a Light Graffiti effect …

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.

Really?

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.

That is what I thought at the beginning.

Shooting with your DSLR

This article is going to give some tips regarding shooting Video with your DSLR and editing it in kdenlive afterwards.

Camera hardware

Lens

Generally Primes are preferred over zooms in video. (Some people, like me, prefer it over zooms as well for photography — but this is a matter of taste and of how you work.) Why that? A psychological reason is that eyes (at least mine) cannot zoom either, so zooming is hardly ever used in video. The technical reason is that Primes are cheaper to build whilst offering better quality: Better sharpness, bigger aperture (for limiting the Depth of Field). Opening the aperture gives you a very nice look. (Please also read ArtInvent’s comment on this.)
Examples for very popular primes are the Nikon 50mm f/1.8D and the Canon 50mm f/1.8 II.
If you own such a lens, just don’t forget that you should not always shoot at f/1.8. ;)
