SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Install the latest kdenlive 21.12.3 on macos 11 (Big Sur) on a MacBook Pro with 64 Gigs of memory, large SSD drive 2. Start a project with a video clip. 3. Start to play the video in order to edit it. OBSERVED RESULT The Preview window doesn't play the video longer than just a few frames. EXPECTED RESULT I expected the video to play nicely in the Preview window as it does in the Linux version. SOFTWARE/OS VERSIONS Windows: macOS: 11.6.4 Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: 5.92.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION
If I had well understood the description of the bug (see after), I have noticed the same problem on a Linux based platform (instead a MacOS one). More precisely: MANJARO-Linux 21.2.6, Linux kernel 5.15.32-1, Kdenlive version 21.12.3, MLT Version 7.6.0, KDE Version 5.92.0, Qt Version 5.15.3. Do we speak about the same bug ? As I’m not sure to have well understood the depicted bug, I give my own description under: The bug appears when I want to load a video clip or a sound clip in my project: A finder window is opened, I have enabled the preview panel inside (F11) in order to have a look on the clip before loading it (or not). But, the clip is not played, only the first frame, apparently, is displayed. No player controller is displayed. Nevertheless, loading of the clip proceeds normally. With an audio clip, no sound is played.
Thank you for reporting. This playback issue on Mac should be solved with version 22.04. Please try to see if it's fixed.

The issue I described applies when I have loaded some clips into a project and dragged some of them to the timeline. It's during editing that I noticed that display in the Preview window would stop after just a couple of frames. Happy to say it is now fixed :-)
(In reply to emohr from comment #2) > Thank you for reporting. This playback issue on Mac should be solved with > version 22.04. Please try to see if it's fixed. Yes, version 22.04 has fixed this issue :-) I have just used my Mac to edit a video over half an hour long with two clips, a sound file and several frame stills, all without this problem appearing at all :-) Thankyou @emohr
Thank you for the feedback and contribution. Glad to hear it works. I close this bug. If it still appears in the latest version, please feel free to re-open it and update the affected version number

Sorry, I've been away from Kendenlive for quite a while, but I'm coming back. I see with kdenlive 23.08.1 the same problems on the preview pannel that I indicated here in my previous comments GO 2022-04-27 15:55:40 UTC. But since this bug report #452466 concerns a macOS platform while mine is a Manjaro Linux, I will leave it unchanged and create a new bug report. Thank's for all. Gérald
