Copying keyframes with interpolation

Hello! I’m learning Kdenlive’s Effect keyframes and have ran into an issue where after copying and pasting keyframes on the same timeline, every keyframe’s interpolation is reset to Linear automatically. I’m making an animation where I have to copy and paste a lot of keyframes on Discrete interpolation, so I’m looking for a way to prevent this from happening if possible.

I have Kdenlive version 25.08.1 and am running it on Linux Mint. The Default Keyframe Type is set to Discrete, but that seems to only apply for making brand new keyframes and not ones that have been pasted. I also noticed that the option to copy all the keyframes to the clipboard and import the keyframes on a different Effect will keep the interpolation of each keyframe as is, as opposed to this.

Hi @Helispark, and welcome to the forum and community.

Thanks for reporting this. I can confirm this behavior for 25.08.3 (Flatpak and appimage on Pop!_OS) as well as RC 25.12

Please open a bug report in the official bug tracker. Instructions are here.

You’re welcome! I’ll open the report soon :>

Okay, I’ve opened the bug report! I’ll close this topic now that I know what’s going on.
