Hey people,

I've reinstalled ubuntu on my computer and when i open my old projects on kdenlive i get the error that says:

File: /media/.../filename.kdenlive is not a valid project file.
Do you want to open a backup file?

I've tried to open the backup files in the folders an for them too the error appear.
I'm currently using ubuntu 14.04 LTS and kdenlive 0.9.10

Here's a screenshot:

Were the project files saved in a version 15.n of kdenlive. The file format changed between these two versions and there is not backwards compatability. Only forward.

Ok,
I've tried to downgrade my kdenlive, but i'm not sure in what version i've made the projects
Here's a screenshot of the synaptic package manager.
My kdenlive now says that is version 0.9.6 and still doesn't open the projects.
How can I install a previous version from that? The synpatin only offers to downgrade from 0.9.10 to 0.9.6

If you open the project files in a text editor it might have some info about the format type in the file.

Right,
These are the first lines:

<?xml version='1.0' encoding='utf-8'?>
<mlt LC_NUMERIC="pt_BR.UTF-8" version="0.9.9" producer="main bin" root="/home/joaorlazaro" title="Anonymous Submission">
<profile display_aspect_num="16" description="HD 720p 30 fps" frame_rate_num="30" progressive="1" colorspace="709" display_aspect_den="9" height="720" sample_aspect_den="1" frame_rate_den="1" width="1280" sample_aspect_num="1"/>

I guess the version we are talking about is 0.9.9, right?

That actually looks like a melt version number. I am away from my PC at the moment so I can not check. So I don't actually know how to tell the difference in the file formats by looking in them. Maybe some one else can tell you. In 24 hours I might be able to get back to you on this.

To recognise a version 0.9.10 .kdenlive file look for a <kdenlivedoc> element. It appears at the end of the file

eg
<kdenlivedoc profile="dv_pal_wide" kdenliveversion="0.9.10" version="0.88" projectfolder="/home/ttguy/Videos">
The document format version number here is 0.88

Newer .kdenlive document formats do not have this <kdenlivedoc> element.

In the newer version of the format there is a property with name kdenlive:docproperties.version and this contains the document version number. In this case is is ver 0.91
eg
<property name="kdenlive:docproperties.version">0.91</property>

.kdenlive documents in version 0.91 of the document format can not be opened by version 0.9.10 of kdenlive.
