I try to create a video based on a recorded TV transport stream. I'm posting this from Germany, where we've got PAL MPEG-2 720×576 at 25fps interlaced. When I render the final video, I'm getting regular freezes (or jumps) in the output. This especially happens when I render in multiple threads. If I render in only one thread, there are also freezes but only at those points, where I cutted the input video. If it helps, I leke to mention, that this issue did not occur in the previous release of kdenlive. (Please forgive my english!)
Please try with the current Kdenlive AppImage version 19.04.0 https://files.kde.org/kdenlive/release/ Or the Kdenlive_Nightly_Appimage https://binary-factory.kde.org/job/Kdenlive_Nightly_Appimage_Build/lastSuccessfulBuild/artifact/ Environment settings: set processing threads to 1. Multithreading is not possible at the moment. Render -> tick “parallel processing” -> tick “more options” -> on the right side set threads to “0”. This is the fastest render setting. If you have problem with the rendered video untick “parallel processing”.
The more than one thread option had been disabled as it is very buggy.
