Description Unknown 2016-09-22 03:08:00 UTC
When I've preview rendered a zone, and make changes to an Effect parameter on a clip IN that zone, the preview render bar shows red where it should. However, when I click on Preview Render, it instantly goes green and uses the cached render files -- it doesn't re-render the clip with the changed effects that I made.

Reproducible: Always

Steps to Reproduce:
1. Preview render a zone in timeline with clips with effects on them.
2. Change some of the parameters to those clips.
3. Re-render same preview zone.

Actual Results:  
Kdenlive uses the already rendered cache files, instead of re-rendering the video clips whose effects I made changes to. I can manually delete the cache, but then I have to re-render everything.

Expected Results:  
When changes are made to an effect on a clip in the Timeline, Kdenlive recognizes it and puts a red bar in the space where a new preview render is needed (which it does). BUT, when I hit Start preview render, I would expect it to re-render the clips that have had their effects parameters changed.

Bug discovered while using Kdenlive 16.11.70 git master build via ppa:kdenlive/kdenlive-master Kubuntu 16.10, KDE Plasma 5.7.2 desktop environment. 

KDE Frameworks 5.24.0

I cannot reproduce. Can you tell me what is your project profile and what are your timeline preview render parameters

Hmm... I did some more testing off of a new project (instead of the one I was using, originally), and it seems like everything is working fine. It could be my project file.

In any case, the feature seems to be working, so I'm closing this bug. Thanks JB!
