As a timelapse and landscape photographer, I need this feature so much!
Birds suddendly appear in different parts of the frame & look like rubbish in the final video.
I know some tricks in AE/Pr how to remove them fast with the Lighten blend mode by duplicating the same footage and moving it 1 frame forward, but it doesn't always work perfectly. It often gives artifacts.
Being a perfectionist, I do it manually frame by frame in PS with the Spot Healing brush.
Can you imagine how time consuming it is? 300-500+ images to clean... At sunrise the birds wake up and are very active. Almost the same thing with the sunsets. That's why I need the feature like birds removal. I'm sure it would be useful for many landscape photographers.
P.S. I can even provide a few timelapse series (hundreds of shots) to train your algorithms.
