Description Evert Vorster 2016-08-08 10:25:22 UTC
I just noticed that I am unable to select an 10,000% speedup on a clip, like what I used to be able. 
 For some reason, the limit now seems to be 2,000%. 

I actually used the 10,000% speedup on very long clips as a type of time-lapse. 

Just being able to type it into the numbers field would be enough. 



Reproducible: Always


Actual Results:  
Artificial limits introduced on range of motion clip. 

Expected Results:  
Unlimited speedups or slowdowns.

Evert, the underlying MLT timewarp producer only allows +/-0.01x to +/-20x (~2000%), see here: https://www.mltframework.org/bin/view/MLT/ProducerTimewarp

So to me this is clearly an upstream feature request to the MLT timewarp producer. Evert, would you mind to head over to the MLT project for your feature request and close this bug report here, at least for the time being until we get an improved timewarp producer?
Comment 2 Evert Vorster 2016-08-09 06:28:38 UTC
I used to be able to specify 10,000%, so this is a regression. Did we start using a different producer, or did the mlt code change?

As people were asking for audio support, Kdenlive started to use the a new producer, the timewarp producer. I don't know how the old speed effect was done.
Comment 4 Evert Vorster 2016-08-09 18:41:57 UTC
I don't see any audio support on the new speed effect, is that still to be implemented?
Comment 5 Wegwerf 2016-08-09 18:57:25 UTC
Evert, you don't *see* audio support? It should be audible, any joking aside. But I'm not sure within which speed range, so it may be limited to a certain speed range only.
Comment 6 Evert Vorster 2016-08-10 05:59:26 UTC
If the speed effect had audio support, one should be able to apply it to an audio clip. 

On my setup audio is automatically split out, and does not resize with the video when the speed is adjusted. 
Ah, I see it does speed up the audio, but only if it is not split out. I guess I will have to file a bug on this one....

Comment 8 Evert Vorster 2016-09-13 18:39:31 UTC
This seems to be fixed with the clip jobs option of changing speed. 

I can specify 10,000% speedup again, with audio support!
