oops, Georg...
I have good news: I'm just a hasty newbie!  :-)

To amend my previous message, here are my further discoveries:


1. There is no need to be unfaithful to Cin. 
Even a project with very keyframed camera zoom curves can zoom out all
the tracks with the projector. I think it is also smarter. In fact the
camera resizes, the projector scales tracks.
I wander if Cin can think separately of canvas size and project output
size (not just single tracks size).


2. In case of a keyframed projector zoom curve, ffmpeg can help better:

$ ffmpeg -i Acqua.mpg -target ntsc-dvd -r 29.97 -sameq -s 600x480
-padleft 60 -padright 60 AcquaNTSC.mpg

Note that I added -target ntsc-dvd that sets automatically all the
format options (bitrate, codecs, buffer sizes) and greatly improves
quality.


3. Since to produce a .mpg file I have to use ffmpeg anyway for muxing
audio and video streams (see Scott's nice Guide at
http://content.serveftp.net/video/renderTest/guideToCinExport.html#exportDVD), 
I can convert from one standard to another in that very pass:

Same standard:
$ ffmpeg -i <filename>.wav -i <filename>.m2v -target dvd
<destinationFilename>.mpg

>From PAL to NTSC:
$ ffmpeg -i <filename>.wav -i <filenamePAL>.m2v -target ntsc-dvd -s
600x480 -padleft 60 -padright 60 <destinationFilenameNTSC>.mpg

>From NTSC to PAL:
$ ffmpeg -i <filename>.wav -i <filenameNTSC>.m2v -target pal-dvd -s
720x480 -padtop 48 -padbottom 48 <destinationFilenamePAL>.mpg


Thanks for listening to my answers to a never asked question.  :-)

Bye
Raffaella
