Thanks for the note. Yeah I really think not copying whatever was on them to a hard drive prior to putting them back in camera was a bad move. I never use the Sony software with the card in camera via USB, just read somewhere a guy recovered files the camera didn’t see using that so tried it out without success. Use the card reader in my Macbook Pro. Save to a unique folder and access that folder to log and transfer in FCE4.
Pretty sure it’s not a card issue. Use SanDisk Extreme 10 32 GB 45 MB/s that BH recommended. Format in camera prior to each use.
Not aware letting data move from A to B slot cards can open you up to problems. Do that pretty commonly. Wonder if that was a challenge for the first cards removal and camera remembered it and it screwed up the third card which ended with the battery dying.
Second battery was a: Power 2000 ACD-712 Rechargeable Battery ( Sony NP-F970 Equivalent ) I don’t recommend it for this camera. Camera can give error message about it sometimes that goes away with a turn off/turn on, it takes forever to charge and its performance is very variable.
Appreciate the mpegstreamclip tip, will look in to it.
