Bug ID: 467740
Summary: After saving, move waveform/thumbnail cache instead of
regenerating
Classification: Applications
Product: kdenlive
Version: 22.12.3
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: ja...@nerdonthestreet.com
Target Milestone: ---
SUMMARY
Kdenlive discards and re-generates data such as audio waveforms if the project
is saved to a new location. This can often mean waiting for waveforms to
generate twice when starting a new project (once before saving for the first
time, and once after.)
STEPS TO REPRODUCE
1. Open Kdenlive
2. Drag a video into the Project Bin
3. Drag the video to the Timeline
4. Wait for some waveforms to appear
5. Save the new project to a non-default directory (e.g. if the project has its
own directory where the footage is stored, save it there)
OBSERVED RESULT
Kdenlive notifies the user: "The location of the project file changed. You
selected to use the location of the project file to save temporary files. This
will move all temporary files from /old/directory to /new/directory, the
project file will then be reloaded"
After this, all audio waveforms are gone and the loading bar under the clip in
the Project Bin restarts from zero to generate them again.
EXPECTED RESULT
The already-generated waveform thumbnails should be moved (as the dialog
indicates) and generating should not start over from zero.
