What is your operating system?
Windows 10 Pro 21H2 build num: 19044.2604
What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
22.06.23 (hopefully 64, it doesn’t say on that panel)
Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
Dragging an image from the filesystem into an empty place on the timeline between clips with the ripple markers on slide the markers on the right 4 hours instead of the expected 4 seconds - which is the default length of the image clip. This is consistent and adds 4 hours as many times I add an image.
Didn’t experiment with it much and can’t change the default image clip length to test if it’s related.
