How about a context menu item "Transcode" with sub items: Replace...,
Add..., or None.... Then, it opens the Render dialog for you to choose
something.

My suggestion above would facilitate "batch transcode outside of the
timeline" at the expense of the inconvenience of the Render dialog
opening for each. An alternative is to have each Render profile as a
sub item of the Transcode context menu item. Maybe this:
Transcode
Add
File rendering
HDV
PAL 1080 50i
...
Replace
None
File rendering
HDV
PAL 1080 50i
...
Heh, it is a labyrinth of sub menus - not good. Hmm... maybe a
Favorites system for Render profiles, where the Favorites appear as
the sub-menu as well as the default "Destination" in the Render
dialog?
Transcode
Add
Favorite 1
...
Favorite N
Replace
Favorite 1
...
Favorite N
None
Favorite 1
...
Favorite N
It would be also be great to handle multi-select!

I think since MLT has multi-threading, and we are trying to increase
the parallelism, that sequential-only makes sense. If this were
managing a clustered rendering system, it would be a different story
:-). Also, eventually MLT will have a multi-consumer option to allow a
single decode and processing, and that will output in parallel.
However, that will require other changes in the dialog.
