Hi Andrea, I haven't really used Cinelerra-GG or made video in over a 
year; I'm caught up with other things. I just have time to read the 
discussions on the list because I find them interesting and hope one day 
to get back to a more concrete use of Cinellerra-GG.

All this to say that I don't think I'm in a good position to make a 
useful contribution to your questioning, which seems to me to be very 

The only thing I'd like to mention is that for a long time I've been 
wondering why the VideoScope Waveform doesn't show image levels that 
exceed 100%. Is it because these levels don't exist?
