Track effects in Kdenlive 0.7.8

A new feature introduced in Kdenlive is track effects. There are several situations where this can be useful, for example:

  • You want to make a black and white movie
  • You need to correct the audio balance of all your clips

So now, with Kdenlive 0.7.8, instead of applying the effect to all clips in timeline, you can simply add the effect to the track, and all clips in that track will have the effect applied.

To apply an effect on a track, just drag & drop an effect from the Effect list widget to your track header (see screenshot on the left). You can then adjust your effect settings just like usual (but note that because we had not enough time, keyframes are not yet supported on track effects).

Introducing Color Scopes: The Histogram

Russian translation online!
Translation by Александр Прокудин (Alexandre Prokoudine)

With kdenlive 0.7.8 I added some color scopes, used for displaying color information. In this section I will give a brief overviews over scopes in general and explain the most basic scope, the histogram, in detail.

Color correction. This is a really important topic in video editing. It starts with simple stretching of the tonal range if the brightness is not ideal, goes on with white balance to ensure that white remains white and not blue, and finally ends with creating looks which make your video look unique. (Remember the blueish Minority Report? The contrasty The Departed?)

For color correction we basically need two things, Effects for changing the colors and Scopes for monitoring the changes. The first scope I'm showing now is, as already mentioned, the histogram:

Development news

Hi everyone!

Here is a quick info on the recent development:

Subversion move

For all those who are getting the Kdenlive source through subversion, we just moved the development to /trunk. If you have a copy of the KDE4 branch, go into it and do:
svn switch https://kdenlive.svn.sourceforge.net/svnroot/kdenlive/trunk/kdenlive

New features

Some of the features that are implemented in the development version and will be part of the next Kdenlive 0.7.3 release:

  • Rendering scripts: You can now create rendering scripts that will allow you to launch the rendering whenever you want by just starting a bash script (image 1)
  • Web updates: We are implementing content update through the web. That means you will be able to download new rendering profiles from within Kdenlive, and sharing will be made easier, more info on that later (image 2)
