Summary0003327: After 'stabilize' clip (transcode) there is .mlt file, as I try to add clip it says 'Invalid clip'
DescriptionAfter I do 'stabilize' clip (transcode) there is only .mlt file with few kb, then as I try to add clip it says 'Invalid clip' - will be moved from project.

Hi there... I'm not a programmer either.
.mlt files make kdenlive really, really unstable.

So, my workaround is to render the stabilzed video seperately, and just add the output video to my projects.

To do thatfrom the command line takes two steps:

melt VIDEO.MP4 -filter videostab2 accuracy=15 shakiness=6 \
stepsize=100 smoothing=20 \
-consumer xml:TMP.MLT all=1 real_time=-2

melt TMP.MLT -consumer avformat:STAB_VIDEO.MP4 acodec=aac ar=48000 ab=512k vcodec=libx264 vb=32000k

Replace VIDEO.MP4 with the name of your video, of course
For more info on what switches to use for melt, look at mlt homepage:

Hi there!
First thanks very much for you help, it would be great if I could do that.
Well, after first command line (melt MVI_0874.MOV -filter videostab2 accuracy=15 shakiness=6 \
stepsize=100 smoothing=20 \
-consumer xml:TMP.MLT all=1 real_time=-2) I get:

"Failed to load "MVI_0874.MOV""
 Usage: melt [options] [producer [name=value]* ]+

any idea why is this happening? do I have to make some special folder?

Thank you,

First stabilizers where unstable, MLT & Kdenlive just enabled a new one, more reliable. Please try daily builds or wait for new version to reach your distribution (~2 months).
(for melt use, see melt manual or ask on forums)
