[Cin] How do I crop a picture-in-picture?

I agree with Rafa in general. But I think it depends on the mix of the 
videos, the variety is important. Most of the videos should not be too 
long up to 5 minutes, as Rafa recommended, but I still enjoy watching a 
longer video from time to time. We should not only address the younger 
people, but all age groups. When a video is well done I watch it, even 
if it is longer. So I don't think there's anything against users 
providing us with a longer video. Of course, most videos should be 
rather short, but from time to time we can also publish longer videos.

If like Igor delivers videos without voice and sound, then we could 
improve the videos a bit. For example, add relaxed background music, and 
from time to time a very short intro of only a few seconds, so that we 
have a Cinlerra-GG branding. If we've done it often enough, then this 
procedure goes very quickly without taking up much of our time.

If you would like to occasionally add a video with sound and native 
language, I think there is nothing wrong with that. You can also create 
a short video without sound from the same video and upload it for the 
English speaking community. As said it depends I believe on a good mix. 
We can work with different playlists.

Google Drive already exists with this account, so I can set it up so 
users can upload it there.

You will get direct access to the channel and can upload it there. 
Please send me a private email with your Google connected email address 
and I will set up everything else.

Thanks for your great and very helpful tips. I am very happy that you 
support this project so much.
