SUMMARY When I'm selecting clips, going back and forth on the timeline with mouse wheel doesn't work. Usually when I have a long project with many clips, I zoom in, to start the selection, then I use the mouse wheel to go back/forth on the timeline to continue selecting clips. This feature doesn't work in 19.12.1. It did work in 18.12.2. Of course, I could zoom back completely to see the complete project on the timeline all at once, but if I have many clips, then it is very hard to see where one ends and the other starts. STEPS TO REPRODUCE 1. Open a project with many clips in the timeline. 2. Zoom in the timeline, press shift, and start the selection. 3. While pressing the shift and left mouse button, try to move the timeline by mousewheel. It does work in 18.12.2, but doesn't work in 19.12.1. OBSERVED RESULT 19.12.1: the mouse wheel doesn't move the timeline during selection. When the clips are not being selected, then the timeline can be moved by the mouse wheel. EXPECTED RESULT During selection the mouse wheel moves the timeline back and forth, so selecting the clips can be continued. SOFTWARE/OS VERSIONS Windows: 19.12.1 ADDITIONAL INFORMATION Workaround: In 19.12.1, there is a small few pixel tall space under the horizontal scrollbar of the timeline. If the mouse pointer is on that space, then the mouse wheel works during selection.
Correct. You have to release shift before you can scroll with the mouse. Ones scrolled, hold shift and you can select further. Yes, when you with the mouse hoover over the not so good visible scroll bar, below the timeline, then you can scroll with holding shift. I don't know if this is a bug or a wish to change.
If I start selecting a clip, and release the shift, then I can scroll the timeline, but the start of the selection doesn't "stick" to the part where I started to select the clips. The selection box just stays at the place while the clips on the timeline moves behind it. It was different in 18.12.2, and I think this would be the correct and expected behavior of selecting clips. (If you want to, I'll make a video of it how selection worked in 18.12 vs in 19.12)
Yes a small video would help. Please upload here.
Here is the video clip: In v18.12 the start of the selection sticks to the actual position of the timeline, while in v19.12 the selection just floats on top of the timeline while the clips are moving behind it. https://drive.google.com/open?id=14x9xeGUYx9GDV2Nf8EGc2QH0wbGOgfv-
And I forget: in 18.12 I don't have to release the shift to move the timeline.
The link in the previous message is not working, the full link contains the "-" at the end. Just copy-paste the link instead of clicking on it. I try to paste it here again, maybe it works this way: "https://drive.google.com/open?id=14x9xeGUYx9GDV2Nf8EGc2QH0wbGOgfv-"
Thanks for noticing this. In fact, we remapped Shift + mouse wheel to vertical scrolling, which explains why selecting while scrolling doesn't work anymore. I agree that your use case is probably more useful so we should find a better way to handle this. Currently we have: Ctrl + click and drag: pan timeline Wheel scroll in timeline headers: vertical scroll Wheel scroll in timeine: horizontal scroll Shift + Wheel scroll in timeine: vertical scroll Wheel in ruler: seek So we should probably drop Shift + Wheel scroll to restore previous behavior. Should we simply drop vertical scroll in timeline ?
The problem is not with the key bindings, but that the beginning of the selection box doesn't stick to the current position of the timeline. Watch the video I attached, and notice that in v18.12 the beginning of the selection "sticked" to the current position of the timeline, so as I scrolled the timeline, the selection box got bigger, so I selected the clips starting from the clip where I pressed shift+mouse button, then scrolled, and the selection ended where I released the mouse button. In v19.12 the selection box just floats on top of the timeline, and the beginning of the selection doesn't move with the clips I started the selection.

I tested it with the newest nightly, but the bug is still there. Should I wait for the final kdenlive? I downloaded kdenlive from here: https://binary-factory.kde.org/job/Kdenlive_Nightly_mingw64/lastSuccessfulBuild/artifact/
Can you please test with the latest version (20.12.3 at the moment, https://kdenlive.org/en/download/) and close this report if it is not relevant anymore?
I just tested it with 20.12.3. The feature is still not working correctly: I start the selection by holding shift and clicking, but when I use the mouse wheel during that, the timeline doesn't goes back or forth. If I move the cursor to the left or right side of the timeline, then the timeline scrolls slowly (as it should), but the mouse wheel doesn't move the timeline at all.
