[Mlt-devel] Non-destructive rendering

[Jean-Michel <jm...@fr...>]

Hello,

We are using MLT and Kdenlive to create a video documentary, sharing
resources over the internet. 

Using Kdenlive, the normal way to proceed is to use DV source files. But
this means that we need 20 Gb disk space for an hour of source files.
This makes it impossible to share source files over the internet.

On the converse, I would like to be able to convert source files ***once
for all*** to high quality Mpeg4. This would allow sharing source files
over the Internet. The final film would be rendered, without major
recoding, except transitions.

I guess this feature is called non-destructive rendering. It basically
is the following command: ffmpeg -acodec copy -vcodec copy ...

Does MLT support non-destructive rendering? 
Are there plans for MLT to support non-destructive rendering in the
future?

MLT is designed for broadcast. I hope that my email can contribute to
explain the needs of individuals, working in communities, over the
internet, trying to produce high quality movies/documentaries. I think
that we really need non-destructive rendering.

Kind regards,
Jean-Michel
