Comment 7 for bug 696863

Hi Andy,

Yes, you are correct, I would expect that importing 373 video clips would
take a lot of time. I was testing 1.3.0 alpha and it took 36 seconds to
import 100 clips and about 1 minute 12 seconds to do 200. When I tried 373
clips all at once, I waited over 20 minutes and OpenShot was hung. Of
course I could try it again and just let the processor run over night. That
wouldn't be a problem for me to try. I can assume that with every instance
of the object that servicing each one will take some time. I love object
technology. I just might give this a try tonight. I did see many
improvements in 1.3.0 alpha. I was able to create a video 1 hour 57 minutes
this time with no problems using 373 video clips. One interesting thing I
discovered was that after I imported 300 clips and then tried the final 73,
OpenShot hung. I then tried importing 10 at a time to finish all of them
and then I was able to drag all of them to the timeline successfully.

Tonight I will try importing all video clips from both memory cards and see
if OpenShot has a problem with 474 clips from two memory cards with some of
the clips having the same file ID. It might not be fair to have video clips
with the same file ID. The problem I have and maybe others is that
sometimes one needs more than one memory card to complete a video although
not many people create 2 hour plus movies as I do.

Please let me know if I can provide any special testing as I can do it with
a large and lengthy video using AVCHD.

Andy, also, the problem with OpenShot (1.3.0) displaying a white screen the
last 2 seconds of a video clip was probably with AVLinux because it wasn't
including the latest libraries and there was really no problem with OpenShot
at all. I did not see this problem last night using 1.3.0 alpha on Ubuntu
10.10.

Thanks again for you great work,

Don

Trying to import that many clips in one go is going to take some time -
for each file that is imported, an Openshot file object is created, an
instance of MLT is created to obtain various properties of the file,
these and other properties are set on the file object, and a frame is
extracted from the clip to use as the thumbnail image - it is an
intensive process.

There haven't been any changes in this area in 1.3, or with regards to
files having the same ID.

Title:
  Problem creating 2 hour plus video

Status in OpenShot Video Editor:
  New

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.
