[kdenlive] [Bug 414006] Spacer tool is prohibitively slow with many timeline clips
https://bugs.kde.org/show_bug.cgi?id=414006 --- Comment #12 from farid --- This should be fixed with https://invent.kde.org/multimedia/kdenlive/-/commit/609278fdfdf3fcb942d2a0812354ffcbb4fce064 and https://invent.kde.org/multimedia/kdenlive/-/commit/19600e4c0e8e34f00f67eaf3e5834a38eb685887 Could you test the master branch and let us know? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=414006 --- Comment #10 from Bill Robinson --- Created attachment 141430 --> https://bugs.kde.org/attachment.cgi?id=141430=edit large project file causing spacer tool to be slow Please find attached the compressed project file that causes the spacer tool to be really slow for me. I can't attach the clips as they're from a personal family project. Thanks -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=414006 --- Comment #9 from Bill Robinson --- Created attachment 141429 --> https://bugs.kde.org/attachment.cgi?id=141429=edit callgrind output using spacer tool on big project I updated to the latest master and also I have tried the sandsmark/martin/texture-cache branch. Both are still about as slow using the spacer tool. I have recorded another doing one move with the spacer tool of a big project with lots of edits. You can uncompress it and then open it with kcachegrind, maybe it's useful. I will also attach the project file -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=414006 --- Comment #2 from Bill Robinson --- So it looks like just shuffling along these clips they are being removed and then reinserted. It appears that Mlt::Playlist::insert_at->mlt_playlist_insert_at is called 360 times and this causes 2,800,000+ calls to mlt_playlist_virtual_refresh and 28,000,000+ calls to mlt_properties_get_data which is where most of the freeze happens. This is making kdenlive unusable for me :( Is it possible to get a version of that timeline-shuffling spacer tool that just changes the start/end properties of the clips instead of removing/re-adding them, because it seems to be very expensive in MLT.
