Yes, I understand that GG and your team are doing more than we could 
imagine. What quality the program has reached at the moment - is already 
amazing. I, like everyone who participates in this newsletter, is 
delighted with Cinelerra-GG and its future prospects. Thank you very 
much for this hard work.
For my part, I, as before, will identify crashes, offer any additions 
and do my best to promote Cinelerra-GG.

Now I'm trying to find out how advanced FFmpeg is to calculate the track 
of a point. If I have such data, it will be possible to write a script 
to fit the second video into the geometry of the green window.
