Hi, I am seeing this issue on a Quad core as well, the interesting thing is if I import a single clip into Openshot and play it back it works, however opening an existing project with many joined short clips from the same source files results in the playback issues, it is so pronounced than on many of the short clips only a single frame is displayed in the preview window.
For what it's worth the files are 1920x1080 .mov files with AVC Video and PCM Audio from a Canon Digital Camera. I'm uploading one for the sake of testing here (May not be finished uploading until a while after I post this): http://bandshed.net/files/MVI_2503.MOV -- 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/770316 Title: Sluggish video preview with mlt 0.7.0 Status in OpenShot Video Editor: New Bug description: 1. Fedora 14 x86_64 2. RPM (RPMFusion) 3. Openshot 1.3.0 I'm the Openshot maintainer for Fedora. I got a but report against mlt in RPMfusion that the upgrade to 0.7.0 made playback sluggish. For him, 1 frame every 10 seconds. A quick test on my system with AVCHD video showed stuttering but still watchable video. Downgrading to mlt 0.6.2 seemed to help. Is 0.7.0 supported or is it too new? Kdenlive doesn't appear to be affected. _______________________________________________ Mailing list: https://launchpad.net/~openshot.developers Post to : [email protected] Unsubscribe : https://launchpad.net/~openshot.developers More help : https://help.launchpad.net/ListHelp
