Description Ilia Lilov 2019-12-04 04:24:10 UTC 
Version of Kdenlive where bug is present: 19.11.80 (it's not present in versions list for reporting, so I chosen "git-master" as the closest). The bug appeared not earlier than 19.04.2 at least.


To reproduce (100% repeatability):
- Run Kdenlive (mandatory; don't use already running process).
- "Project" -> "Add Clip or Folder", add any video file. Answer to "Switch to clip profile...?" dialog does not matter.
- Drag and drop the clip to any video track on timeline.
- Move the clip at leftmost position of the track on timeline (proven to be mandatory step).
- "File" -> "New", choose any profile, saving project or not does not matter.
- "Project" -> "Add Clip or Folder", add any other video file, file profile must not match project profile. Ignore "Switch to clip profile...?" dialog or answer "Cancel".
- Drag and drop the clip to any video track. Leading video thumbnail of the clip will be from the first clip, not from the second as expected.


In my case, differences between project profile and clip profile are the following:

Project:
Frame size: 1920 x 1080 (16:9)
Frame rate: 25 fps
Pixel Aspect Ratio: 1
Color Space: ITU-R 709
Interlaced: no

Clip:
Frame size: 1920 x 1080 (1920:1080)
Frame rate: 25 fps
Pixel Aspect Ratio: 1
Color Space: ITU-R 601
Interlaced: no
