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.

Don

Hey Don,
It is great that you found a workaround and that you are still using
OpenShot. It would be great if you could find out the exact number of video
clips you are able to import before OpenShot hangs. The total size of the
video clips would also help too. Hopefully once bug 642320 gets fixed you
will be able to import all of your video clips at once. I will not mark this
bug as a duplicate because you have a problem with the ceiling of the number
of video clips. 

Can anyone else confirm this ceiling while using SD clips?

Title:
  Problem creating 2 hour plus video

Status in OpenShot Video Editor:
  Confirmed

Bug description:
  Congratulation for a great video editor!!!  Here's my objective.
  Using OpenShot 2.2.1 on Ubunti 10.10. Camera is Panasonic ZS7 shooting
  AVCHD lite.  1) Problem importing 200 clips at one time.  Successful
  doing 100 at a time then after 200 clips were imported, I needed to
  back of to 25 at a time.  It seemed to take too much time trying
  another 100 clips after 200 clips were imported.  I was able to
  successfully import 372 (0000 to 0371) clips from one memory card then
  another 103 (0000 to 102) clips from a second. 2) Problem with the
  small icons with each imported video clip.  I had two memory cards,
  the clips were imported from both of them and the second memory card
  had clips 0000 through 103 which was the same id as the other memory
  card's clips.  The actual video was correct but the small icons from
  the second set of clips displayed on the first set of clips. 3)
  Problem with the 300rd clip.  At about 1 hour 26 minutes when I added
  clip 300 to the timeline, the timeline pointer would disapear when I
  tried to view any of the video. It would disapear about 2 seconds at
  the beginning of the video.   Also, OpenShot started crashing. Also,
  earlier, the timeline pointer and it's line would become out of sync
  with each other.  The line seemed to be on video but it's pointer was
  to the right of the line and when the line hit the center point of the
  timeline, they would become aligned.   I had to eliminate clips back
  to about 1 hour 10 minutes then OpenShot seemed to behave enough that
  I could continue with the video in two parts, about an hour each.  I
  had previously added a title at the beginning of the video and I was
  not able to go back and work with it.  When I selected the title I was
  not able to bring up "Font Properties" but I was able to bring up both
  "Pick a Colors".  I deleted the title and created a new one.  No
  problems with exporting to DVD and creating a DVD from it.  The video
  is about one hour 12 minutes long.  I will continue with the next 1
  hour video.  I don't know how many people try to make a 2 hour plus
  movie but I think this was a good test.  Please let me know if more
  information is needed.  I am at work and quickly wrote the above.  I
  hope it isn't too confusing and please E-mail me with any questions.
  Thanks for a great video editor and I hope this makes it even more
  amazing than it already is.
