Kdenlive/Manual/Clip Menu/Edit Clip
Edit Clip
This option is available from Clip Menu for audio and image files. It is greyed out for video clips. It opens the clip in an external editor.
Selecting on audio clips causes the audio editing software specified in → → → Default Apps → to open the audio clip ready for editing. Audacity is the app that is configured by default to be the audio editing tool for Kdenlive.
Selecting on image clips causes the image editing software specified in → → → Default Apps → to open the image file ready for editing. GIMP is the app that is configured by default to be the audio editing tool for Kdenlive.
The option is not available for video clips because Kdenlive is the video editor - only audio and image clips are edited by external software.
