Description Egor 2015-09-24 09:20:57 UTC

When I open project which was saved in old kdenlive version kdenlive says that my project now saved in the new format. If I close kdenlive and open my project again some clips missed in the timeline, but still available and playable in project monitor.

Details in screenshots:

Project (old and new format versions): https://dl.dropboxusercontent.com/u/59794362/kdenlive-wrong-save-to-new-format/kdenlive-wrong-save-to-new-format.tar.gz

Reproducible: Always

Steps to Reproduce:
1. Open project in old format.
2. Kdenlive says that it converts project to new format.
3. Save project and close Kdenlive.
4. Open saved project.
5. You can see that some clips disappear from timeline. But video from missed clips still shows in project monitor.

Actual Results:

Thanks for your detailed report. I have not yet managed to reproduce but will work on it in the next 2 days - so a fix should be available soon.

Some clips still hidden in timelapse.
For example in the same project no one clip at 2:30 and 19:30 in timeline. But video still played in project monitor here.

Can you please save the project file created by latest git and attach it here so that I can understand what is happening ?

Comment 12 Egor 2015-09-28 21:10:41 UTC

Sorry, but same bug again.
Now I open the file in old format, save to new, reopen it and all seems ok.
Then I reload all files in the project tree, save project, reopen it and now most of clips in timeline disappear again.

Comment 15 Egor 2015-12-14 10:33:31 UTC

This bug still present in latest git (b03db9329bf392fdba3fa8982972a9021cac9b4b). It very annoying and stops me from using modern kdenlive on my projects which I started on previous versions. So, for now, I stuck with kdenlive 0.9.10 in my workflow.

When I try to work with converted project in modern kdenlive after some edits and save-open cycles I see missed clips in timeline.
Each time when I use "reload clip" feature from project bin and then save and reopen project some clips disappears from timeline, but still playable in project monitor.

Comment 16 Wegwerf 2016-07-30 11:10:21 UTC

Egor, can you please try again with a recent Kdenlive 16.04.2 release? Also, can you please supply some information as to which clips go missing: are there speed effects on them? Anything with the paths to these clips? What kind of clips are these? A/V clips? Title clips? Something else? Are these clips still in the project bin?
