Sentry Crash Report:
Attachments:	Kdenlive file with imagesequence Missing files dialogue

Description Paul Brown 2020-11-29 10:20:12 UTC

SUMMARY

When opening projects that contain sequences of images, Kdenlive will complain that the sequences are missing and show the dialogue that lets you search for the sequences. Even when the dialogue is pointing to the correct directory, Kdenlive will be unable to find the sequence.

STEPS TO REPRODUCE

1. Open a project containing a sequence of images.

OBSERVED RESULT

Kdenlive will be unable to find the sequence and show a dialogue to help the user find it in their tree of directories.

EXPECTED RESULT

As long as the sequence has not been moved or deleted, Kdenlive should open the project without a problem.

SOFTWARE/OS VERSIONS

Operating System: Manjaro Linux
KDE Plasma Version: 5.20.3
KDE Frameworks Version: 5.76.0
Qt Version: 5.15.2
Kernel Version: 5.9.11-2-MANJARO

ADDITIONAL INFORMATION

There is a workaround: ignore the offer to search for the sequence and click on "Use placeholders for missing clips". This will load the project correctly.

Thanks for your report. I am unable to reproduce. Could you attach the .kdenlive project file, or at least part of it (if you open it in a text editor), look for something like this, it is what I need to understand (a <producer> tag with the property "resource" pointing to your image sequence folder):

(I have to image sequences).

Comment 3 Jean-Baptiste Mardelle 2020-12-03 21:13:25 UTC

Hmm, everything looks normal in that part of the xml. Could you mail me or attach the full project file and a screenshot of the dialog saying the sequence is missing ?

Comment 4 Paul Brown 2020-12-03 21:45:35 UTC

Created attachment 133853 [details]

File giving the error. I have reproduced this in other files too.

Comment 5 Paul Brown 2020-12-03 21:46:43 UTC
