This makes me think that it is not written clear enough.

When Rescaled to project size (FFMPEG only) is UNchecked, you can not to 
use the Title or Sketcher plugins, for example.
You have to use a workaround; You can see an example in "Animated Split 
Screens" tutorial ( https://www.youtube.com/watch?v=YCqJnHLmj6s ) from 
1m:56s, where I use the Cinelerra-GG Snapshot feature to "convert" the 
white line to a PNG. Sometimes you have to use Inkscape to create Title 
and exporting it to PNG that you load in Cinelerra-GG, instead of using 
Title plugin.

The table was drawn after I wrote the text because I thought it was more 
immediate to understand but I don't know if you could create it in LaTex.
