Stretch keyframes over time (to a shorter duration) without losing any of them

Hello,
I have some keyframes which are staggered over time, some are 1 keyframe apart, if I select them all and scale them down to a shorter duration, the keyframes that are 1 keyframe apart start getting deleted/merged and the animation becomes completely corrupted, is there a way to do a time scaling operation which preserves / protects all present keyframes? so if you shrunk it down as small as you can you would result with all present keyframes next to eachother?
Thanks!

Hi Nick N,

This sounds very close to the Snapping setting being ON. Especially Frame Snapping. You find all settings for Snapping In the Timeline Menu> Edit.

Let me know if that works for you.

Please have a look as well here:

This seems to help a little, but frames still get destroyed https://www.dropbox.com/s/5g3zgbdklq2wpm3/frameSnap.mp4?dl=0

Thanks for the extra information, Nick N.

When they get squeezed that much, I would set them to linear before scaling. Perhaps you need to set a new keyframe if the progression of the curve during 2-3 frames is important.

More I can tell with a scene file, as usual. I see how far I got with just a suggestion missing the scene file, it is a waste of time. Sorry that I tired even. I have to stop doing that. A scene file is the only true reply.

Let me know if you need an upload link (I use only Dropbox, Amazon, Google, Adobe or Apple, no other cloud.)

Cheers

P.S.: I have tried now many scenarios, and I can’t replicate the problem when I have Snap as well as Frame-snap set to off.
Please explore the file below, if you can, so we get more data about the problem.

Ahh I’m sorry! I misunderstood and thought you meant to enable frame snap, but you meant to disable it! then no keyframes get lost. Sorry, and thank you! All working perfectly now

Thanks for the reply, Nick N.

Yes, any snapping off. Timeline Snapping pulls the keys to a specific position and with that on top of each other. Since only one value can exist at once, any other is deleted.

Cheers
