You mean the menu File->Render ? i.e. export from CV ? But cinelerra does
not have the option 'smart copy' as in Avidemux.

Einar says that there are noticeable differences between directly copied
and decoded/encoded areas.
I want to compare directly copied frames and re-encodes ones, but I do not
understand what steps I should do for getting these frames.
