I put in an extract of section 20.5 of the CinCV manual here:
http://cinelerra-cv.wikidot.com/cincv-manual-en:rendering-files

    Most of the time you will want to bring in the rendered output and
    fine tune the timing on the timeline. Also some file formats like
    MPEG can not be direct copied. Because of this, the jobs are left in
    individual files.

    You can load these by creating a new track and specifying
    concatenate to existing tracks in the load dialog. Files which
    support direct copy can be concatenated into a single file by
    rendering to the same file format with renderfarm disabled. Also to
    get direct copy, the track dimensions, output dimensions, and asset
    dimensions must be equal.

    MPEG files or files which do not support direct copy have to be
    concatenated with a command line utility. MPEG files can be
    concatenated with cat.

By reading the parallell email thread "[Cin] fileexr/fileppm direct copy 
support", I wonder if this isn't equivalent to some other NLE's "Smart 
Rendering" or "by-pass re-encode/compression when possible"? If so it 
would be fine to get this dealed with in the CinGG manual ....?

And maybe also another CinGG theme "HDV on a Blu-ray without re-encode" 
as discussed earlier, is related and needs some manual update?
