Something that’s been bothering me with Kdenlive, despite how niche this may or may not be, is that there’s, to my knowledge, no effect that allows me to adjust the frame rate at which effects and video is played.
I’m unsure if there’s something I’m missing, but needing to use a workaround by duplicating my clips to a separate layer and applying the Alpha Strobe affect to both of them- at differing times- just gets flat-out annoying, and the freeze effect (once more, to my knowledge) doesn’t actually apply any of the effects beforehand, meaning that effects just don’t play.
I’d like to see something akin to Shotcut’s “Choppy” effect. The effect, when applied, allows the user to limit the frame rate of a clip all while affecting the effects stack. I’m unsure if this is something that’s already implemented, and I just haven’t figured it out yet, but it would be well appreciated nonetheless.
I did a bit of digging, and it turns out it’s mlt effect, the same effect library that kdenlive uses, which only kind of adds to my confusion.
Hi @Wildpaintbrush, and welcome to the forum and community.
Let me see what I can do to make the Choppy effect available in Kdenlive. Normally, all effects MLT knows about are in Kdenlive, but in this case something went wrong and it doesn’t show up. Bear with me for a while, ok? Thanks!

Thanks for the warm welcome, and double thanks for looking into it!
I’ll be honest, I was really only on this forum because I was looking for a way to get the Choppy effect from shotcut into kdenlive. I even did a little bit of rummaging through the source code, and it’s just straight-up not listed under the preferred_effects list nor the included_effects list.
Something I also noticed that “choppy” was listed under the excluded_effects list, marked as either “Not working, not useful on the timeline, or heavy”. I’m not sure which is which. If I had to guess, I would wager “not useful on the timeline”- since, by all means, it I could see lowering the framerate of a clip could being glazed over as “not useful on the timeline” or maybe something about kdenlive itself causes it to break or something. I’m not familiar with Kdenlive’s source personally, and even if I was, I don’t know enough C or C++ or anything like that to properly determine any potential issues.
Thanks again!
