Description gionata.prinzo 2018-08-16 14:04:13 UTC

I tried to use the "Contrast" effect or the "lift/gamma/gain". They seem to work properly initially. But when I make a preview render or a render, the video in which I put the effect disappear completely. They are like replaced with a grey/black screen. Help!

(windows 10 - graphic card AMD Radeon r7 + Radeon rx 460)

This is a bug and should be solved with upcoming 18.08 release (Bug 364127). You can try this 18.08 version from here: https://files.kde.org/kdenlive/release/Kdenlive-18.08.0-w64.7z.

I made a quick test and it seems to work.

But the Play bug still exists. And the remaining processes too, after you end Kdenlive and which you have to kill via batch.

Ok I'll give it a look and I'll let you know! Thanks.
