--- Comment #7 from emohr <fritzib...@gmx.net> --- Created attachment 120392 --> https://bugs.kde.org/attachment.cgi?id=120392&action=edit Proxy clip_Render-settings I tested creating proxy from PNG, MTS and MKV and it works. Could you check if it creates the proxy files in the cache/proxy folder as shown in the screenshot. Yes playback is slow with CPU only. We found a bottle neck in MLT which slow down playback with picture. This will be solved with the 19.08 version. Rendering: enable parallel processing and set thread to 0 for using all cores. If you get a black output file disable parallel processing. -- You are receiving this mail because: You are watching all bug changes.
