Hi fellow AX100ers -
I have not looked at this thread in a long time. If any of you, like me, have had issues with files not being 'finalized' over the years and you have saved the corrupted mp4 files looking for a fix, I may have just found the 'free' Holy Grail answer.
I have read about businesses that can attempt recovery of the files at great expense.
I even purchased the updated Grau Video Repair Tool program which purports to work with the AX100 in its 'included camera' list on their website now. It did not work even with repeated 'options' setting changes and efforts. $120 not refundable : (
This YouTube link came from me scouring the internet for 4K mp4 file recovery.
This is not a come on or business advertisement. This is legitimately the result of me needing to desperately recover an hour and 35 minute concert set I shot with my AX100. The lineage goes AX100 PNY 256gb SD card>SD card reader> Windows laptop> external hard drive>got home - hard drive died>sent to Seagate's recovery team>30 days later received back a corrupt 65 gb mp4 file that had played flawlessly when I transferred it = me = ready to explode!!
2 DOS based PC programs, the broken .mp4 AX100 file, a perfect .mp4 AX100 file and the superb detail of the video's author completely saved and restored this non-playable file to its original pristine condition.
If you have been fortunate to never get a corrupt mp4 file from your AX100, rock on! Continued excellent luck to you. If you have and you saved it somewhere, this may well be worth a look and your time. Again, I did not author it. I have no $ interest - there is none. I just love this Sony camera and wanted to offer the potential 'silver bullet' to others on this forum who have lived this frustration as well.
