Frequently Asked Questions
What components does Kdenlive use?
In effect, Kdenlive is a front end to melt - which uses the MLT video framework. The MLT video framework relies on the FFMPEG project. Kdenlive writes sh.mlt XML files that code the edit points and transitions and it then calls /usr/bin/kdenlive_render and /usr/bin/melt to render the video.
How do I fix Audio Sync Issues?
Often this is caused by having mixtures of different audio sources in the project. Audio encoded with VBR (be it pure audio like MP3 or video with audio) can be problematic.
To fix ...
If your audio source is from a video file try extracting the audio from your video sources and transcoding the audio to WAV format. If you use the Extract Audio feature of Kdenlive to do this it will write a .wav file for you.
If you have a pure audio source try transcoding that to WAV.
