Corrupt frames at the beginning of the clip

[Michael Kirschenlohr]

Hi guys,

sorry if somebody else has written about this issue but I couldn't find anything about it here.

We're shooting with 2 different R1's (one with SSD- and one with CF-Card-Reader, both on build 30.7.0) and both record sometimes the same error:
The first frame of the clip is ok., but the 2nd till 4th frame have a strong colorshift. It looks like only the colors are going nuts- the movement in these frames is still continued. We're shooting 3K 16:9, RC36 and 25 fps.

Since these errors always appear in the slate-part of the clip it is not really a problem, but where is it coming from? I haven't seen these errors on RED-Drives, but that doesn't meen that it's a flash-thing... Can also have something to do with the firmware and/or our settings...

Has anybody seen something like this and when?

Most likely a copy problem from cables or other stuff.
I'd recommend using disk arbitrator to mount read only also.

That's a nice tool, thanx for the hint- I'll give it a try.
