Thanks for the information. Can you recommend any programs or another technique to remove these bad columns in post? I don't mind the aliasing until I can get a new cam. I'll take a look at canon's own bad pixel correction in the mean time.

Camera Emergency Department / Canon 7D - Black vertical lines on images/video/live view
August 28, 2019, 01:58:09 PM
Hello all! My first time posting here. Sad that it had to be for this reason. I've searched around and couldn't find a solution to this exact issue. Someone mentioned having this problem in passing, but couldn't remember their solution. First off I've had my 7D Mk1 for about 10 months. I bought it used with only about 5k clicks on it. Right now the shutter count is 21k. I've been using ML on it for about 9 months with no problems whatsoever.
I was out shooting some RAW clips of wildlife in my area 2 days ago and after recording a few clips, these black vertical lines appear in live view. I decided to restart the camera, and the problem was solved. I didn't think much of it. The following day I went out to get some more raw video and discovered I had left the camera on overnight in my bag. Didn't think it would be a problem as I had it on auto power off after 2 minutes. But the battery was dead. Popped in a second battery and the dreaded black vertical lines are back, and they would not go away. These lines are evenly spaced throughout the entire image, with 7 pixels between them.
Here is a list of things I have tried so far:
- Inserting different CF cards, one with ML another without
- Resetting ML settings
- Uninstalling ML
- Reinstalling ML
- Clearing all camera settings and custom functions
- Removing camera battery and clock battery, letting it sit overnight
None of these things have made a difference. Is there anything else I can try?
I'm not really sure where to upload these images to so I've just placed them on google drive. If there is a better place to host these images, please let me know.
This is an image taken as soon as the problem started occurring

And this is an image taken with the Silent pic mode from ML
