All my packages are for Ubuntu
A pre-release package of kdenlive 0.8 is now ready in ppa:sunab/kdenlive-release
As usual daily development snapshots are in ppa:sunab/kdenlive-svn

Are your packages stable ? Because i use kdenlive-svn, and with mlt-0.7, its crashy. With mlt-0.6.2 its ok.

If they are stable, how did you do ?

In the kdenlive source tree, at this moment, v0.8 requires mlt 0.7.0.
Stability is a very specific question, I used kdenlive-svn packages along mlt 0.7-git series for 8 hour of common work without any crash.
Can you describe a crash precisely, i will try to reproduce it.

Add 5-6 effects to HD video, try to play it, it should be laggy, pause it, it crashes.

At this moment I am not able to reproduce this kind of crash using mlt 0.7.0
I have tested with many AVCHD clips in a new project {with and without activating proxy option}, added 7 effects on each clip (defish, mirror, B, dust, speed, scale and tilt, denoiser). It is extremely laggy, but no crash.

The lag thing is normal, not sufficient cpu horse power with only one core working. According to mlt developer multi-threading is in very early stage.

Your project file (file.kdenlive) was created long time ago? which versions of kdenlive/mlt used to create it?
Does it crash if you create a brand new project?
Are you using the experimental processing threads option of kdenlive? (Settings > Kdenlive Settings > Environment)

Note : I am not a kdenlive developer, I only make some packages to help Ubuntu users to try the latest features without the compiling the kdenlive stack by themselves.

Dont remember. How can i know it ?
Does it crash if you create a brand new project?
Wow. Very strange. I created a new project, no crash. wtf ?!
Are you using the experimental processing threads option of kdenlive? (Settings > Kdenlive Settings > Environment)
No

A .kdenlive project file is an xml structure.
Explore your old .kdenlive file with a text editor. Search for "kdenliveversion="

This xml structure can change along time with kdenlive/mlt new features. Maybe there is a "problem" when handling an "old" project file?

Can you post your old project file (which causes the crash).

Here is the line about the version :

I have to agree with this sentiment. Stability PLEASE.

I have been using (attempting) Kdenlive for over 2 years. I've installed from repositories, I've used the builder, I've compiled the source myself, I've done it all.

Kdenlive has great potential, it could be way ahead of all of the rest of Linux video editors, all except for one thing.

Stability.

All of these extra new features, such as light graffiti, vector scopes, ect are wonderful ideas... if and when the software just worked with out crashing.

I know, you the developers put a lot of time into Kdenlive, and don't get paid for it. We should be all be thankful that Kdenlive even exists.

But please, please, could you invest some time into stabilising Kdenlive so that it is a reliable and usable production tool?

I don't have to restart Gimp because it crashed after a few edits. It just does it's job. And I want to do my "job"; edit videos.

If I could, I would get involved with the programming and help you out. Instead, I file crash reports (as detailed as possible) to help out with pin pointing the issues.

Again, thanks for the great work so far, but please, invest more time in stability than new features.
