Possible Corruption or Compression Error

[Shawn Seifert]

Hi everyone.

Just got called from the director of today's production saying that the first shot of the day (all four takes) have a weird issue. None of the rest of the footage appears to have any problems. Part of the frame appears to have compressed incorrectly, but this is just a wild guess as I have not had a chance to look at the footage in person. I will be doing so tomorrow. The Director has sent me 2 screen grabs.

As far as I can remember the camera was not rebooted after this take and I did not notice anything weird in the monitor.

What is going on here?

Can you send us an r3d still frame?

It doesn't look like a compression problem but more like a copy problem.
See if they can hold the original mag.

Hey Deanan,

I will get that to you in a few hours when I can get my hands on the original mags.

However, these stills were pulled directly off the mag, so no copying had been done yet.

A bad mag pull without unmounting or a bad unmount on the computer side can also cause a filesystem to corrupt.
The pointers to where the files are can then get mixed up.

I know the mag was pulled from the camera when the camera was powered off. However I can not speak to if it was ejected incorrectly from a computer once it was out of my teams hands. I'll be sending you an email with a r3d still frame momentarily. I also have access to each of the original problem clips if needed.

creepy effect, definitely going back to original media should help clear things up. Was this CF, Red Drive or SSD? Is the director using RCX to review or transcoded media?
