Hi Jonathan, firstly love your tutorials, you’re very clear and concise and easy to follow.
I have a question – I’ve been trying to follow along with your cleaning of keyframes and channels but I’m running into an issue.
Following the video at ~0.39 in the Dope Sheet, after I’ve selected the source list and cleaned all channels, it behaves as expected and removes all channels that have bones without keyframes.
My issue is 0.45 when I select all my keyframes and hit clean keyframes blender doesn’t delete the constant keyframes, they persist and I’m unsure why.
I attached a screen cap – any idea why this would be happening?

Thanks, Darren
