5d3 raw footage processing error

[anandkamal]

hi.. sometimes my footage does not play in MLRawViewer, the screen is fully black, I thought its a mistake and proceeded to convert the .raw to cdngs. The converter shows "0 FPS" and crashes. The footage is 1.5 to 2gb in size. Is that footage a shooting mistake? i don't think so bcos other footage are good. Am I wrong at something? Why would that happen? (the take I okay-ed is unfortunately showing this error  )
