I have cutlist info in a db - filename,start,end - start and end are absolute, typically the start/end of the file.

I would like to use kdenlive_render and a .mlt to add a title and credits and transcode the whole thing to .ogg.

I was able to do it for single files by saving a dummy .mlt and then using string substation to tweak it for different filenames, but trying to do that for multiple files seems clunky.

Any suggestions?


print ep.id, ep.name
cl = Cut_List.objects.filter(episode=ep).order_by('sequence')
for c in cl:
print (c.raw_file.filename, c.start,c.end)

First, do not use kdenlive_render unless you need the KDE4 Jobs/Notification integration. kdenlive_render just calls 'melt' to do the heavy work. So, just use melt. Secondly, it seems you need to consult the documentation section of mltframework.org for a guide to its XML schema.

That is the format kdenlive saves to when you do File/Save,
"Kdenlive video project document" foo.kdenlive

right?
