And what permissions should I set?

Read by owner and group, at least. Writing is not obliged, since Kdenlive will not write them.

First of all I'm pasting a post from another thread here, followed by some comments:

After rendering (with youtube profile if it matters), my title clips show up as a screen-filling string "Invalid" in mplayer.
I'm using today's svn/git versions of ffmpeg, mlt and kdenlive.

As was pointed out by fillods, there seems to be a problem with the resource line. The "/" at the beginning of the path in the property tag seems to cause the renderer to interpret that path as an absolute path. I changed

<property name="resource" >/titles/title000.png</property>

into

<property name="resource" >titles/title000.png</property>


and everything rendered properly.


I thought this would be easy to reproduce, but instead it doesn't happen anymore and all titles are saved using a (correct) absolute path... :s

I think, after 3 years that problem would be solved or is no longer relevant.

I bumped at the same problem.
Is there any bug opened for that to follow it?

best regards,

I'm using kdenlive 0.9.2, and I get the same "INVALID" text when using XCF files. Funny thing is that the file's content is displayed properly in the preview window, but rendering doesn't seem to work. I think this is not a problem with the XML property, but something deeper.

There was a bug last year, but if I understand correctly you'll need the qimage library plugin for .xcf files part of KDE. Paul above posted to the MLT team in Oct 2012, got the qimage plugin answer so try that, this threads been dug up twice now, a quick google search using the words MLT framework .xcf provided the info.

HaHa, I just rendered a 13gb dv video file into an x264 file and

1. It rendered in 14 minutes!
2. Displayed white text "INVALID" when playing

So I cleared the clips, loaded another clip, tried some different settings, and it rendered the same.

So, I shut down kdenlive and restarted, and it worked fine rendering again.

Odd behaviour, I've never seen the INVALID text appear for any reason other than a loss of link to a clip for example on an unmounted drive or renamed folder, or if I delete an image file or video whilst that project is open and that clip is in the project tree.
