Description Alexander Vishnevskii 2019-10-25 07:57:16 UTC 
SUMMARY
When I add LumaLiftGainGamma effect to the video clip, I can't change Lift and Gain parameters. Changing Gamma works - both typing and dragging the bar, but Lift and Gain always stuck at 0,000.

STEPS TO REPRODUCE
1. Add any clip to a project
2. Add LumaLiftGainGamma effect to the clip.
3. Try to change Lift or Gain parameters.

OBSERVED RESULT
Lift and Gain remain 0,000

EXPECTED RESULT
Well, I expected them to change.

SOFTWARE/OS VERSIONS
Windows: Windows 10 Pro (Russian language)


ADDITIONAL INFORMATION
Tried 19.08.2 and earlier versions of kdenlive - same result.

Thank you for the feedback. Yes this is still an issue under Windows only. I added to issue https://invent.kde.org/kde/kdenlive/issues/78. 

Do you get any error message by loading old projects?

Can you open the original project file in a text editor and look for: kdenlive:docproperties.decimalPoint
What is it? . or , ?
Comment 7 Alexander Vishnevskii 2019-11-03 13:49:22 UTC
