SUMMARY After switching two video files (A -> tmp; B -> A; tmp -> B) on disk, the static and the video thumbnails remain as they were. For file B, the thumbnail for A is shown and vice versa. Rebuilding all thumbnails does not change the video thumbnails. Recalculating the checksums might work(?). However, this is still running (and has been for a while now - we are at 3% after ~20 minutes...) I would like to be able to re-create the videothumbnails for a selection of files only. STEPS TO REPRODUCE 1. have database with video clips and videothumbnails 2. take any two files A and B and switch their filenames using cli or any file manager (not KPA!) 3. view the thumbnails OBSERVED RESULT The videothumbnail for A is the old one of what is now B and vice versa. EXPECTED RESULT This is the expected result, as we were not telling KPA that. MY RFQ: Now, I would like to remedy the situation and rebuild the thumbnails (and only those) for just these two files, while keeping the meta-data as they were: meta-A -> A(new). In other words: - select a few files - say: "rebuild videothumbnail for selected files" - have only these few files rebuild - do not touch any meta data, except maybe the checksums of the selected files KPA: v5.8.1-21-g7f709159 KDE Frameworks 5.76.0 Qt 5.12.7 (built against 5.12.7)
