If it helps, earlier in the editing process, Shotcut crashed and I had to restore the file from a backup (ie. filename = “foo - Repaired.mlt”). I also moved a few files and had to relocate them, but this is probably irrelevant because the file that caused the export to fail wasn’t moved. the export is still running, and probably will be for some time (I’m a filter addict). I’ll let you know of the results.
