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.

Hi,
Thanks for this big test, who is interesting for us, because a major part of us have not yet so much of rush in AVCHD. And when we are testing they are not so long than your test.
Be careful, using the zoom bar which give a crash with the timeline pointer (=the play head).
Could you test with the last development version (1.3.0 alpha) who brings a lot of correction (same if she is an alpha don't exempt of bugs). I think that you could be benefit for you.
Don' t worry, it is without danger for your system and you can keep the "official " version. It is a big advantage of Python. No compilation is needed.

Hi,

Thanks for the reply! I'll test my video with 1.3.0 alpha and see if I can
create a two hour video and send you my results. I was on a cruise recently
and all their video is being shot with AVCHD so it seems the industry is
starting to use it in a big way.

Thanks again,

Don

Hi Again,

OK, last night I used OpenShot 1.3.0 alpha, and it performed much better
than 2.2.1. but I still had a problem. First for the good, the pointer and
line that follows the timeline behaved very well and stayed aligned with
each other in comparison to 2.2.1. Also, when clicking on various parts of
the timeline, the pointer positioned itself much quicker. I was able to
drag to the timeline 372 clips which was about 1 hour 57 minutes of video
which I was able to play normally and the pointer did not disappear this
time when playing the video. The response time was greatly improved when
bouncing around throughout the video. This time I did not create any titles
but I will with my next tests.

The problem I had was that I couldn't import 372 clips all at once. I think
the same problem is still present from 2.2.1. I waited over 20 minutes and
OpenShot was hung. I then tried importing 100 clips at a time, clips 0 to
100, then 101 to 200, then 201 to 300, then 301 to 372 which didn't work and
hung OpenShot. I then tried importing clips 0 to 200 which worked, then 201
to 300 which worked and then in increments of 10, I imported the remaining
clips 301 to 372 which worked. I then drug each clip to the timeline making
a total video of about 1 hour 57 minutes.

One other minor problem, I was not able to successfully open a project in
1.3.0 alpha that I created in 2.2.1. I had to create a new project for
1.3.0 alpha.

I did not import clips 0 to 103 from the second memory card this time. I
wanted to see if I could just work with the first memory card's video clips
which would give me almost 2 hours of video. Tonight I will continue
testing and this time I will import all the video clips from both memory
cards and see if that makes a difference and creates any problems when
OpenShot has to work with video clips that have the same ID.

Thanks again,

Don

Hi,

My total project is 373 clips from one memory card (16 gig SD card size) and
103 clips from a second memory card (4 gig SD card size). I can get the
total size in terms of actual gigabytes tonight when I get home. I would
guess that it's around 10 to 15 gigabytes totaled. I'm running a Quad Care
Q8400 system with 2 gig memory. Last nights test was only using video clips
from the larger memory card that had 373 video clips.

I created my project using 1.2.2-1 and couldn't open it in 1.3.0 alpha.

Thanks very much for the quick response,

Don

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

Hi Andy,

I did a little more testing last night with my 2 hour plus video. I was
able to import 103 video files all at once successfully after I had
previously imported 373 video files. The thumbnails were correct this time
and the video files with the same file IDs showed correct pictures. I want
to do a little more testing in the area of importing large numbers of video
files. I don't want you to go on a wild goose chase in the event I am wrong
that there is a problem with importing large numbers of video files. Also,
I drug every video clip to the timeline to create a total video of around 2
hours 37 minutes and then I created a simple title at the beginning and end
of the video. Then I exported the video to DVD with no problems. I had no
problems viewing or manipulating the video so, so far so good.

One simple note, it would be nice if I could drag more than one video clip
to the timeline.

Thanks again for all your great work; I'll keep you informed,

Don

So far so good about creating a 2 hour plus movie using 1.3.0 alpha. The
only testing I need to complete is importing large numbers of clips at once.
I think I might still have a problem here. I will keep you informed.

Hi Andy,

Last night I tried again to import 373 AVCHD video files (they all resided
on the hard drive) and this time I let it process for over 2 hours. After
waiting this long, OpenShot was hung and I had to logoff in order to
terminate OpenShot. Other than this I can't think of any other problems
accept for a very little one that I couldn't open a project I created in
2.2.1 with 1.3.0 alpha although I'm not really worried or concerned about
that one.

Please let me know if I can be of any further testing assistance.

Thanks again,

Don

Might it also be worthwhile copying the files to your HD first? Just
wondering what effect the read speed of a memory card might have
(especially with large AVCHD files).

Hi Andy,

I'm sorry, I keep getting the version level wrong. When I say 2.2.1 I mean
1.2.2. I noticed this finally.

Hi John

Nice hearing from you. Let me give you an update regarding OpenShot. I
used your latest version 1.3.0 to create a 2 hour plus video, the same video
clips as I used with your previous version that I had importing problems
with. Here are my findings. Version 1.3.0 is much improved over your
previous version. I have a Panasonic ZS7 which produces individual AVCHD
720P video clips. I was still unable to import over 300 individual video
clips all at one time so I tried importing a few at a time and gradually
working up to all of them. It's been awhile now so I don't remember the
exact number but I did hit a ceiling where I couldn't import even one more
clip still leaving over 100 clips more to import, so this was my solution.
For example, let's say I have 400 clips. I import 200 at one time and
render all of them to create one large clip, then I start over and import
and render the remaining 200 clips to create a second large video clip. Now
I have my entire 2 hour plus video contained in two very large video clips.
Now I'm able to import those two large clips and work with the entire movie.
The only problem is that when editing the video, the scenes are no longer
separated into individual clips and when I need to get rid of bad video, I
then mark it and delete it and close the gap. Other than that importing
problem, I am very happy with OpenShot. If the problem never gets fixed,
then at least I have a solution. I don't have the specs in front of me but
my PC is a quad core with 2 gig of ram.

If it is important, when I get a chance, if you want me to, I can experiment
and find out the exact total number of video clips I'm able to import before
OpenShot hangs.

Thanks very much in advance,

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?

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 ...

I also sometimes use more than one memorycard and gets duplicate names of the clips. My solution is to rename the clips so that the second cards file names begins with the letter "a" instead of a zero.

First card:
00000.mts
00001.mts
...

Second card:
a0000.mts
a0001.mts
....

This can be done in a Bash shell prompt in Linux with the following command (cd to the folder with your mts files first):

for o in *;do n=`echo "$o"|awk '{print "a" substr($0,2)}'`;mv "$o" "$n";done

Hi Tobias,

Thanks for this suggestion. I'll give it a try. I have another problem
I've been dealing with. My videos can contain 350 plus clips. Sometimes I
have a real problem importing all of them which can cause Openshot to hang.
Also, when I finally do get them all imported, I start editing out the bad
video which means if I, lets say, clip out a portion of video clip 0001,
then I need to drag over to fill the gap all the other video clips which
might mean dragging 300 clips which takes a lot of time. My solution was to
import and drag all the clips to the timeline, render them all to one big
video clip, then import the single big video file. That way I can clip out
the bad pieces and just move the one large clip to the left to close the
gap. Now for my next problem, as I work through the movie, it takes longer
and longer and longer to make a change. It gets to the point that it can
take several minutes per change, for example, adding a transition, a title,
or just moving to a new location on the timeline. I was thinking that I have
a quad q8400 Intel processor and I'm running 32 bit Ubuntu with 2 gig
memory. I was thinking about a memory problem because my videos can be up
to 16 gig and larger. I was thinking about installing 64 bit Ubuntu. Do
you have any thoughts regarding that?

Again, thanks for the suggestion,

Don
