I'm attaching a screengrab from a video I was shooting at a party. Every now and then I would get glitches like this. Its never happened before but it happened a few times during the night. Was using a YN50 1.4 because it was in low light. Card used was sandisk extreme plus 90mb/sec. The card is only a few months old and never given problems before.

Video settings were FHD 25.00P

would love to hear feedback or suggestions so it doesn't happen again. Thanks.

p.s the white box over the mans face is just for privacy and not part of the video.

Cards fail, so can you repeat it with another card? Transfers to computers also get corrupted as do card readers.

Does the video show the issue when viewed in the camera?

You can narrow it down by.

1. Is the video ok when viewed in camera?

If OK, then its in the transfer process or in the computer.

2. If its bad in the camera, then its either the camera or video card. The card is likely, does it work with a different card? You can run a check on the card to see if its ok, there are utilities available to test it that write to each cell and then read it back.

3. Do a full format of the card in a computer. The camera full format takes advantage of a card feature that resets all the memory cells at once, but does not check to see if they all play back properly. A full format in a computer takes a long time because it writes to each cell and then reads it back which usually detects bad cells.

3. If the issue happens with a 2nd card, then send your camera in for repair. It can be difficult to determine if a card has defective areas, because the issue only happens when a file attempts to write to the failing memory cells.

I'd also test with a Canon lens. Third party lenses, particularly from the likes of Yongnuo, can cause wonky things sometimes on Canon cameras.
