Hi all,

These are stills from footage I shot on my 5D3 using an always reliable Sandisk 45MB/s SD card (don't recall if it was IPB or ALLI mode unfortunately - bit rate of the footage averages 89Mbits/second).

It appears in almost every clip I have shot.

What gives????

Ehm, I did see exactly the same issue posted on this forum a while ago? Can't find the thread though.

Hello John,

We tried to help John Carrithers with his problem and we provided a solution to repair the damaged clips affected by the same issue you're describing. All points to a malfunction of your 5D Mk III body that corrupts part of the footage.

Please send us a repair request using Treasured • Tool for Video Diagnostics and Repair (http://aeroquartet.com/movierepair/download) in case you're on a Mac computer.

In case you're on a PC then use MP4repair.org (http://mp4repair.org) to diagnose the file.

Regards,
Javier

Hi all,

These are stills from footage I shot on my 5D3 using an always reliable Sandisk 45MB/s SD card (don't recall if it was IPB or ALLI mode unfortunately - bit rate of the footage averages 89Mbits/second).If it's 89Mbps then it must be All-I. IPB is around 30Mbps. By way of comparison a 5D2 records at about 40Mbps.
