Timeline does not represent what plays back

Hi all,

First post.. I've been trying to use kdenlive for a while now but I always fall foul of the same problem. I'm sure I'm doing something wrong but I've read the documentation and I can't work out what.

I'm using kdenlive 0.7.5 on Kubuntu Karmic (KDE 4.4.0)

I have some video I want to edit. It is a PAL MPEG file recorded from a DVB source (using MythTV). 25fps, interlaced, 720x576, 16x9 PAR.

I create a new project and use the profile DV/DVD Widescreen PAL, which looks as though it has the settings to match my source video.
I import the clip into kdenlive and using the clip monitor I set a zone start and end for the first part I want to use. I drag that to track 1 on the timeline. This is where the first problem starts. If I switch to the project monitor and play the timeline, it always assumes my clip is right at the start of the track. In fact, the position of the clip on the timeline appears to mean nothing. I can even drag it so it sits across two tracks!

So I leave it right at the start and go back to the clip monitor and select another portion of the video and drag that to the timeline. After this I really can't explain what's going on as no edits I make on the timeline appear to have any effect on the project at all except to confuse matters still further.

What's going on? Does anybody have any suggestions?

Re: Timeline does not represent what plays back

I'll just add that I've just upgraded to 0.7.6 from the ppa as detailed on this site (not a simple job, masses of dependency problems) but the behaviour has not changed.

The problems with KDE 4.4 (actually QT 4.6) are resolved in the upcoming Kdenlive 0.7.7

Re: Timeline does not represent what plays back

OK thanks, I thought it might be something like that.

I knew upgrading to 4.4 from a ppa would turn out to be a bad idea.. :)

Re: Timeline does not represent what plays back

Problem persists in sunab's repo for .7.7. on KDE 4.4

I'm wondering if there is a conflict with mlt, as ubuntu's repos might have installed a different version, but it looks like I'm using sunab's version.

It's broken for me too, Kubuntu 9.10 KDE SC 4.4 :: Qt 4.6.* :: Kdenlive 7.7

For me, The clips don't actually snap to the timeline at all, but free float.
If I save and reopen the project, the clips are all strewn in sequence on the topmost track.

Re: Timeline does not represent what plays back

I am hesitant to open this up as a bug, as so far this appears to be a Kubuntu only issue, which may or may not be an issue with the sunab builds.

Can any opensuse, debian, etc user let us know if this bug still persists for them (it is marked as resolved in mantis)?

Re: Timeline does not represent what plays back

Here in Archlinux it is resolved (manual compile).
Maybe the package creator did not upgrade to KDE 4.4 /Qt 4.6 before compiling.

Re: Timeline does not represent what plays back

I'm thinking the last poster has the answer.. KDE4.4 is only available on Kubuntu if you upgrade using the kubuntu beta PPA. More than likely the packager is still running KDE3.5...I'm disappointed but that's the way it goes sometimes :-)

Re: Timeline does not represent what plays back

I'm trying to do some research now to see if I can build it. I'm slammed with projects I'm working on, but I thought it is worth a shot.

It looks like ubuntu has an auto-builder tool that creates the ppa, and that might not include 4.4 since it is backported. A deb file for each architecture might be needed instead to get around that deficiency. I'm on 64bit, and I have a desktop running 32bit I may be able to use as well. I've never done this before (although I have compiled projects before, I'm just not sure how to handle dependencies).

^ Confirming the same problem on openSUSE 11.2, with KDE SC 4.4 from the factory repos, and with Kdenlive 0.7.7 from the packman repos. Am performing a system-wide update now in case it's a dependency that's the culprit. I'll report back if it is.

Re: Timeline does not represent what plays back

OK, all you Kubuntu users, it works if you build from source - therefore confirming the bugfix and the fact that the package is built against KDE 3.5

I did this as follows (NB this is not for beginners)
Ensured I had deb-src repositories enabled for everything (this involves editing /etc/apt/sources.list and /etc/apt/source.list.d/*.list)
Installed all the '-dev' dependencies as detailed on this site under Source->Download. Make sure you have libmtl-dev and libmlt++-dev
apt-get source kdenlive
cd kdenlive-0.7.7
dpkg-buildpackage -rfakeroot -uc -b
cd ..
sudo apt-get remove kdenlive-data (answer 'Y')
sudo dpkg -i kdenlive-data_0.7.7-0ubuntu0~karmic1_all.deb
sudo dpkg -i kdenlive_0.7.7-0ubuntu0~karmic1_i386.deb

Took me about 20 minutes. Got to love dpkg and apt and Debian packaging in general :-)

Re: Timeline does not represent what plays back

Tried it that way, and I'm getting an error when it is trying to tail a debian/changelog, which does not exist. I guess I'll just have to compile everything from scratch.

getting the source for kdenlive by using apt-get only gets the 7.5 source (from the repos). I downloaded the source from the soureforge page.

Re: Timeline does not represent what plays back

Ok, I uploaded the amd64 bit file, and it seems to be working on my machine:

http://rapidshare.com/files/353116836/kdenlive-.7.7-1_amd64.deb.html

Let me know if there are any issues. I built the package using checkinstall, as that is what I used on previous compiles.

Re: Timeline does not represent what plays back

Just a follow up - the problem doesn't seem to occur if I build 0.7.7 from source in openSUSE KDE SC 4.4. So I guess it's a packaging problem as well.

Re: Timeline does not represent what plays back

For OpenSuse users, the package in the Build Service works fine, so no need to compile it yourself unless you're a maochist :-)

Yet more evidence to suggest this is a packaging issue, but it's interesting that both the Kubuntu and Packman repositories had the same problem.

"getting the source for kdenlive by using apt-get only gets the 7.5 source (from the repos). "

That's because you haven't manually added the deb-src repository for the PPA. I did, and apt-get source gets the source for 0.7.7 - deb-src http://ppa.launchpad.net/sunab/ppa/ubuntu karmic main

PPAs and backports repos frequently don't add their deb-src counterpart. Personally, I think it's a bug. I've long been in the habit of adding them in manually.

Re: Timeline does not represent what plays back

And here is the i386 file:

http://rapidshare.com/files/353568541/Kdenlive-7.7-i386.deb

Please note:

A. You should install sunab's mlt first. If it doesn't work from that, then let me know and I'll upload the mlt files I compiled as well

B. These files will not be auto-updated like ppa's and the rest of the system.

C. I will do my best to help anyone, but since this is kind of a rare situation with backports, I do not intend to keep up with file updates. If there is another release of kdenlive before Lucid (which I doubt), then I will do it again.

Let me know if there are any issues.

Re: Timeline does not represent what plays back

DrG,
Still had some issues with dev packages not being installed, so I ended up just compiling from the sources per the very helpful guide. I ran into a few stupid issues with dependencies, but I was eventually able to figure it out. Thanks a ton for the deb-src info - I had no idea you could download the source so easily.

Could you please updload the file in another place because rapidshare is alway overloaded (for exemple http://dl.free.fr/)

Hi cryophallion,

Thanks for preparing the packages, but could you please host them where I can download them? Rapidshare has no free slots left so the packages are unreachable for me (and others, too)...

Re: Timeline does not represent what plays back

If you are using kde 4.4 you need kdenlive to be built against it, that is not the case in my stable ppa (using regular kde 4.3). But to satisfy the audience I just rebuild kdenlive against kde 4.4 in my unstable ppa (ppa:sunab/sunab2), so normally those problems are gone ...

Hi,

i've just installed the new kde4-kdenlive-0.7.7.1-0.pm.1.1.i586 and still the same.
Doesn't anybody know how to get rid of this issue. Kdenlive is not usable this way :-(

Thanks for feedback

Re: Timeline does not represent what plays back

Hi,

seems i have the same problem, too. Inserted clips won't snap to the timeline. They can be positioned everywhere in the timeline, even on the lines that separete the tracks.

And the project monitor does not play, what is shown in the timeline. The marker might be over the clip on track 1, but the monitor shows the last added clip e.g. on track 2 (or between track 2 and 3).

I can't even delete the clips in the timeline. The error-message appears (freely translated from german): "Error with deleting clip from track 0". Even if there is no clip on track 0.

I am using Opensuse 11.1, KDE 4.4.0, Kdenlive 0.7.7.1 (packman).

Right now, kdenlive is not usable for me.

Any solutions without compiling the packages on my own?

Is it the same problem as here : http://www.kdenlive.org/mantis/view.php?id=1394 and http://www.kdenlive.org/mantis/view.php?id=1479 ?

It appears to be a qt4.6 related issue. You need the latest versions of Kdenlive and Qt.

Re: Timeline does not represent what plays back

Yes, seems to be the same problem. I am already using latest release of kdenlive.

I updated qt and re-installed kdenlive, but nothing changed. Still the same problem.

Maybe it's the kdenlive-package from packman, that is not correct?

Re: Timeline does not represent what plays back

I am using a 64-bit openSUSE-11.2 with the "official" for openSUSE KDE-4.3.5, and I do NOT have this problem.

My guess is this is specific to the unofficial KDE-4.4 version that you are using and hence it is NOT an openSUSE packaging problem (yet) because the packman packager are to package for the "official" openSUSE-11.2 KDE release and not some official version for 11.2. Novell/SuSE-GmbH do NOT yet support KDE-4.4 on a released openSUSE (although openSUSE-11.3 will have KDE-4.4.x)

Sorry to read of your problem, but if its KDE-4.4 introduced, then that is a risk of not sticking with the released version for openSUSE-11.2.

Re: Timeline does not represent what plays back

Hi,

it is Opensuse 11.1 that´s running on my system. I don´t even know, which is the official supported version of KDE on 11.1.

But i think kdenlive should work with any current version of KDE 4. Some people have the same problems on Kubuntu.

So it might not be a solution of the problem to tell the people "use only the offical version of the distributors".

Re: Timeline does not represent what plays back

KDE 4.4 is not really an official version on opensuse, it's a factory version which means that KDE 4.4. is still under development. Both the en* and de* opensuse KDE upgrade sites tell you about a factory version - at least in the repository name.

Installing beta versions may lead to some trouble now and then...

Just my 2 cents...
