The error, paired with the menu used to import the EXR sequence with default settings.

SUMMARY

I am unable to import EXR sequences in Kdenlive as of this week. I asked about this on KDE Discuss, and was informed that it's likely a bug: https://discuss.kde.org/t/unable-to-import-exr-sequences-into-kdelive/31382

STEPS TO REPRODUCE

1. Download the "singlepart" EXR sequence from OpenEXR's official website here: https://openexr.com/en/latest/test_images/index.html

2. Right-click in the Project Bin, select "Add Image Sequence...", and choose the location of the EXR sequence.

OBSERVED RESULT

The error "Cannot open file qimage:/EXRSequenceLocation/.all.exr" appears in an orange box in the Project Bin.

EXPECTED RESULT

The EXR sequence is imported and can be edited in the timeline as video.

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: Fedora Workstation 41
KDE Plasma Version: (I'm currently using GNOME 47, sorry)
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.2

ADDITIONAL INFORMATION

I booted into Windows 11, downloaded the latest portable version of Kdenlive (I had never used Kdenlive on Windows before), repeated the steps above, and encountered the same error.

Thank you for reporting. I can confirm the crash/issue. Following your steps. 

Loading one of the exr files I get the error: Duration of file singlepart.0001.exr cannot be determined.
