Raw Video / 650d Noise Artifacts
January 24, 2019, 05:20:05 PM
Hello

My previous post has been awaiting approval for several days so I'm posting again hoping this will be approved. These large dashes appear when shooting in low light and cannot be removed using ACR. They are not dead pixels as they change from frame to frame. Can someone enlighten me on what they are and how they can be removed? I'm using Mac. Thank you!

Raw Video / 650d Flickering dots in low light videos
January 17, 2019, 11:57:13 AM
Hello

I noticed strange flickering dots (usually red/blue/white) in videos with high ISO around 1600 onwards. They don't look like colour noise to me and are pretty big.

I am using 650d, raw 1600x680 2.35:1, 10 bits and 14 bits. Converted to DNGs using MLVFS with 2x2 chroma smoothing to remove the focus dots.

Does anyone know what causes the dots, and if it is possible to remove them? ACR did not work.
Attached a screenshot below. YouTube link is https://www.youtube.com/watch?v=kk71SaJ7cWY.

Thanks!
