[ovirt-devel] Screen casting and video editing on fc21 with Blender
Hi guys As you already know, some of us need to do some video/screen cast for their 3.6 new features I spent my day today in recording and editing a video for one of my new 3.6 features and I want to share my experience to save you time (and hair..) Well, I started with recordmydesktop (yum) to capture the video files , this worked smooth and enables you also to have a cup of coffee until the file is written to the disk. Then, after having few videos, I wanted to edit them and make a whole smooth video, cutting some stuff out ... I had started with installing pitivi (yum), from its feature list it seems promising but after dozens of crashes on almost every mouse move, I really gave up... Oved, sent me this post [1]: So, I installed Blender and tried to work with it but it seems to refuse adding my video files to the project time-line ... Digging around [2], I found that the Blender package on fc21 does not work well and in order to get it working you have to download Blender latest version (2.75a) manually from [3], extract it to a directory and run blender Blender has many usages, but you can adjust it to do video editing, just follow [4] [5] and [6] tutorials (less than 15 min for all) (all are important, especially the first one that includes proper configuration) One major issue is to configure well the frames per second rate (fps) (can be shown on the file properties) of your videos if you don't want to get a gap between your video and the sound track I was able after that to edit my videos and export (render) video as MP4 and audio as MP3 (embedded in the video file) (other formats may have codec issues...) Overall, I worked with Blender few hours, splitting videos, removing video strips , grabbing and dragging without a single error or crash Although that Blender learning curve seems to be longer than other applications, I recommend to use this application for video editing and screen casting If you have any question or need any assistance/advice , I will be happy to help.

[ovirt-devel] Registration duplication?
Hey, I've seen that some new code landed to support Engine registration using the generic registration approach. But it seem that we now have two implementations: 1. vdsm-tool register [0] 2. ovirt-register [1] To reduce code duplication I'd suggest to drop one of these approaches before we enter 3.6. Or are there reasons for keeping both of them? My take is to keep ovirt-register which is independent and would allow us to add plain hosts to Engine (host-deploy is then taking care of the rest IIUIC). The vdsm-tool approach reuqires vdsm to be installed. Thoughts?

Re: [ovirt-devel] Registration duplication?
Maybe better is to figure out who requested it to be part of vdsm-tool and why, while there were open bugs to have standalone tool. - Original Message - From: Fabian Deutsch fdeut...@redhat.com To: Douglas Landgraf dland...@redhat.com, Dan Kenigsberg dan...@redhat.com, Alon Bar-Lev abar...@redhat.com Cc: devel@ovirt.org Sent: Wednesday, July 22, 2015 4:42:37 PM Subject: [ovirt-devel] Registration duplication?

The vdsm-tool approach reuqires vdsm to be installed. Thoughts? +1 for dropping vdsm-tool register verb. It started as alternative and later we merged everything in ovirt-register project which is the generic registration. I can send a patch to drop it soon. Right. So let's see what Dan replies and then we can possibly drop the duplicate effort. Thanks fabian ___ Devel mailing list Devel@ovirt.org http://lists.ovirt.org/mailman/listinfo/devel
