Frequently asked questions

Here is a list of common questions:

Can I test Kdenlive on my Windows computer?

No: Not now but maybe someone will port it. Meanwhile you can run Kdenlive on any of the many free Linux distributions. Give it a try, you may like it so much that the question of running it on Windows becomes moot.
Yes: download a CD-boot only GNU/Linux distribution including Kdenlive 0.7.

How do I adjust the volume of a clip?

Apply the "volume" audio effect.

A line will show up in the waveform of the clip.

If you double click any point on that line, a new keyframe will be added in which you can adjust the level.

If you then double-click on the keyframe (it appears as a square on the line) you can then manually type in the desired level or shift the keyframe to an exact time.

How do I make a video crossfade/dissolve between two clips?

Kdenlive 0.7 does not have a video crossfade/dissolve transition by default.

You can either use a "composite" transition or a "luma" transition to achieve a crossfade.

For a luma transition, just use one that "looks right". With composite, you can get a real crossfade/dissolve by applying a composite transition, then add a keyframe to the end of the transition and set its opacity to 0.

For some more discussion of the composite transition, please see mantis issue 261.

How to add a transparent image to a project?

Add the image to the project, then double click on the image in the project tree.

This will show a dialog with an option saying "Transparent background". Just check that box, and then when the image is inserted in the timeline, an alpha transparency transition will be added automatically.
