Then processor usage goes to 100% video goes choppy and audio stutters. bug affects to all types of video files I've tried. -- You received this bug notification because you are a member of OpenShot Developers, which is subscribed to OpenShot Video Editor. https://bugs.launchpad.net/bugs/719296 Title: choppy playback on timeline Status in OpenShot Video Editor: Incomplete Bug description: I have tried out 1.3 a bit, and the first thing I noticed was that playback on the timeline is very choppy. Also the playhead "shivers" during playback. When I double click a fil in the Project Files area, it plays just fine. But it is not possible for me to edit anything like this. The same video files have been fine in previous versions. Linux Mint 9 OpenShot 1.3 from PPA, upgraded via Synaptic Video files I have tried are motion jpg .avi, 640x480, 30 fps. _______________________________________________ Mailing list: https://launchpad.net/~openshot.developers Post to : [email protected] Unsubscribe : https://launchpad.net/~openshot.developers More help : https://help.launchpad.net/ListHelp
