Maybe a stupid question, but can someone clarify what happends when 
typical a source mepg2 video file is loaded into Cinelerra, on the time 
line and available as a Media asset in Ressources?

That is, does Cinelerra have (use) its own "internal format" for video 
and audio, so that already after loading, the source file has been 
decoded from the source mpeg2 ? And next to render this to the "same 
mpeg2", is re-encode and/or passthrough used?

Doing this with Cinelerra-gg 5.1 and "try FFmpeg first" mode set, the 
Media info in Ressources say the file format is "FFMPEG" and list more 
in the details.
