Some more data points: adding largefile to untrunc.pro:CONFIG changes behavior slightly:

Note: no "No codec found" complaint, and a repair attempt resulted in:

Well some progress at least as it started to do something. Great.
Unfortunately, it creates just a file with 1801 bytes. A tad small for a repaired 2.5G source file:
-rw-r--r-- 1 hp xxxx 2682257408 20. Jul 19:49 DJI_0003-defect.MOV
-rw-r--r-- 1 hp xxxx 1801 20. Jul 23:27 DJI_0003-defect.MOV_fixed.mp4

Please let me know, if I can do anything to help you to resolve the issue(s).
