Hi John, Sorry I haven't contact you lately but I've been very busy with my current project at work. I do have some information for you. For some reason, maybe a library function has been improved because I've been able to import all 370 plus video clips all at once, but I still have problems. The problem is that if I import all video clips all at once to the timeline, and then I preview the video and clip out the bad video which leaves a gap, I need to drag each video clip on the timeline to the left to close the gap which takes a lot of time. I might have to drag 300 clips. Maybe there is a function to do this but I haven't found it. So I changed my method of doing my video editing. I start by importing just a few video clips at a time and previewing them and cutting out the bad video. As the video clips became many, say over 200, OpenShot started bogging down and taking very long to remove bad video, so I had another solution. I first moved all 370 plus clips to the timeline. Then I render to DVD quality 480 X 720 from 720 X 1280. Then I start all over with OpenShot, import and used this large video clip to edit. I'm able to go through the video and clip out the bad video and just move the one large video clip to close the gap. Now for the next problem, with a large number of video clips, as I move my way through the movie, it takes longer and longer to make changes as the movie becomes more and more complicated or as I make changes to the video clips by removing the bad portions. When I make a change to the video after deleting the bad video, let's say I move to the beginning and put a title in, then it might take 5 or more minutes to make that change. If I add some video and just want to preview it, it might take 5 or 6 more minutes to do that. It seems for small videos, OpenShot works just fine but for longer videos over 1.5 hours with many video clips, it starts to bog down and take very very long to edit, make adjustments and to just move around the video. It also starts to affect the viewing of the video which becomes quite jerky. If I exit OpenShot and then bring it back up and reload the project, then for awhile it is somewhat better but will bog down quite quickly as the movie becomes more complicated and I add features or move around the video clips. I tried an experiment which I really hated to do because I really really love OpenShot and the great work you guys are doing but just maybe it might help improve OpenShot! Using OpenShot I imported all 370 plus clips to the timeline and rendered to AVI/Mpeg4. Then I created titles and rendered them to AVI/Mpeg4. I copy them to an usb hard drive, unplugged my linux disk and plug in my Windows XP disk and copied the files to a windows directory. I brought up Windows Movie Maker (disgusting!) and I import the titles and video clips to it. Even with my quad processor it takes about 15 to 20 minutes to get the video imported to WMM, then a few more minutes to move the video to the timeline. I'm now able to move very quickly throughout the video and remove the bad video, put transitions in and complete my movie. I almost need to use both of them, that is, use the great features of OpenShot, and use the ability to move quickly around the video using Windows Movie Maker. It seems that WMM is taking a lot of time to setup its data structures, but when completed, I'm able to quite quickly move around, edit and preview the video easily. I'm hoping this information is of some help. Please let me know if I can do any additional testing with large video files. I'm not sure how many people create movies as long as I do, but I know that sometimes it takes a long time to perfect an application and I think you guys are doing a great job. I consistently been trying to get myself off of Windows and replacing whatever I do there with Linux applications and I'm confident that this will happen with OpenShot.
