Bug ID: 474564
Summary: Inserting and removing time operations are very slow
in a long project
Classification: Applications
Product: kdenlive
Version: 23.08.0
Platform: Debian unstable
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org
Reporter: jacklebe...@yahoo.com
Target Milestone: ---
SUMMARY
Inserting and removing time operations are very slow in a large project. The
project is about 5 hours long with many, many small clips. Inserting or
removing time near the beginning takes several minutes to complete, with no
feedback in the interface that any work is being done (such as the progress
indicator seen when analyzing audio).
Probably much unnecessary work (maybe triggering redraws or similar) is being
done for each clip whose offset is being adjusted, as the delay is proportional
to the number of clips after the playhead.
STEPS TO REPRODUCE
1. Have a very long project
2. Insert or remove time near the beginning
OBSERVED RESULT
Takes an unreasonable amount of time
EXPECTED RESULT
Works instantly.
ADDITIONAL INFORMATION
None
