I made a video how you can load a video clip from a directory into kdenlive.
We can see that handling long lists (of files) is problematic.
“FILTERING by file-attributes” would improve that situation a lot.
The only filter which is available in that inport dialog is that of “supported file formats” which even does’nt recognize all file formats supported by Kdenlive.
Rearranging the files in different directories so that only a limited number of
files would be in one directory would create a different problem.
