I was filming a full gig yesterday with latest nightly build for the 5D mark II and I noticed that the recording sometimes stopped before the usual 12min/4Gb capacity and did not restart automatically like I asked ML to do.
Now I just checked my videos and some of them are not able to open in VLC at all. Another one plays ok until half way then the image freezes and a loud hiss noise can be heard until the end. It does the same in Premiere pro.
I tried several recovery softwares for the unreadable files and it could recover half of the files at best. And you have to pay for all of them.
Which leaves me with 20min of missing footage.
I've read it could be a problem with the index? Not sure what that is or how to fix this.
