Hi there, Riku. 

I personally use a package called SlowmoVideo. It very slow, but does
interpolation between frames and is very high quality. I did submit a bug, it
might be a quick fix. 

Kind regards,

AFAIK, the current code base is not maintained so this bug will not get a fix.
After the timeline refactoring is finished, the devs will introduce a rewritten
speed effect fixing all these issues.

So speed effect is totally broken on 17.12.0. It use to work for me at least
with 17.04. Now there is no way to do slow motion? Clip job duplicate with
speed change wont work either...

same here. a bug i remember from 0.9.8

When applying the speed effect, often the timeline gets messed up in an
unpredictable way, one thing that happened to me (on larger projects, so it is
hard to reproduce with a view steps): the effect works well, but other clips
get messed up or become invisible , but play back correctly. also vice versa:
clips added to the timeline get played back correctly, but when i render the
timeline the new clip stays black, etc.. 

@evert forster this is a helpful information! the speed effect would better
just be removed! or what i did lately: open a project with the one file you
need the speedeffect, render it out "lossless" with the speed effect and insert
it into your project.. it s cumbersome, but safes you from messing up
everything..

Well, our great vpinon, just released a windows build for the refactoring
version: 

https://files.kde.org/kdenlive/unstable/kdenlive-refactoring-20170621-w64.7z

NB: Remember this is pre-alpha software.

Excellent news!
I will be happy to test, but I'm a Windows user and I guess the fix will take a
while to propagate to the Windows builds?

Soon we will release an alpha version of the refactoring branch which will fix
this issues. Stay tuned and help us test it if you can.

I experience similar symptoms without using speed effect. Instead I'm an avid
user of ripple delete (mark in, mark out, shift-x). A similar situation
eventually happens, duplicate clips created, they cannot be moved or deleted,
timeline has empty spaces that cannot be fixed. Restarting kdenlive sometimes
helps. This bug is frequent, but very hard to reproduce on purpose.

Seriously, the speed effect is broken. 

Just use the "reverse clip" clip job and set a playback speed. 
This is the only way I can reliably change the playback speed of a clip in
kdenlive and not have the corruption issues.

hopefully all this timeline corruptions will be fixed after the refactoring.

Sad. Still using ffmpeg to render separate variants of the clips where I need
to change the speed.

Mikhas' I know how you feel and I have stopped using the speed effect in
Kdenlive due to the corruption issues. We are starting to do a timeline
refactoring to fix all this corruption issues and will is due to be released in
April. Please contact the mailing list to see ways how you can help out. 

Thanks for your support.

That looks eerily familiar. 

In all honesty, I don't think kdenlive handles the changing of the clip length
in the timeline very well. The speed effect is thoroughly broken, and really
should be depreciated and get a warning. 

The good news here is that the "reverse clip" clip job has been modified to
handle any speed form -10,000% to 10,000%. 
This gives you an .mlt file with the desired speed. Kdenlive's handling of .mlt
files is rock solid, and you get sound support thrown in for free, even if you
have automatically split video. Also, proxies work on .mlt files. 

I hope this helps?

So after the corruption happens, close the project and start it again. You will
see duplicated clips created. Those clips are invisible in the timeline before
restarting the project. (See video.)
