Well in theory, that's a good idea. The problem is that currently changing a 
project from one format to another is broken... But it's a good idea, as soon 
as it is fixed, I will change the rendering dialog to remove other standard 
exports...

Yes, todo.

I will look into this.

Juan, I am wondering which version of Kdenlive you are using. It seems to me 
that some of your requests are already integrated in development version...

For sure, some help to setup good profiles would be very welcome.

Not sure about it, but having different encoders is currently not possible in 
an easy way.

To make it in an efficient way, that would probably require some changes to 
MLT...

Done, you can now have fun and keep an eye on your export!
