--- Comment #10 from Jean-Baptiste Mardelle <j...@kdenlive.org> --- There are currently 2 ways to generate thumbnails in Kdenlive: 1- if "Use FFMpeg for audiothumbs" is selected, we use an ffmpeg command to extract audio thumbnails data 2 - If "Use FFMpeg..." is not selected, we go through MLT to create the thumbnails. Method 1 was recently added, it has the advantage of being much faster. @Chris: * Can you tell me which MLT and FFMpeg versions you have ? * When FFmepg audio thumbs is enabled, you say some clips don't get thumbnails. Is it random, or do some clip types never have thumbnails ? If it seems related to clip type, can you paste here the output of this command: ffmpeg -i myclip.mp4 (where myclip.mp4 is a clip that shows no audio thumbs) ? The audio thumbnails are stored in the project folder, in a "thumbs" folder, and end with "_audio.png". The default project folder is "$HOME/kdenlive", so thumbs go in "$HOME/kdenlive/thumbs/" You can delete a project's thumbs by going to "Project > Project Settings > Project Files > Clear Cache". Note that this will delete audio and video thumbnails. Then you need to close Kdenlive and re-open, or choose "Revert" from the file menu. Changing project profile is not a recommanded option... -- You are receiving this mail because: You are watching all bug changes.
