Greetings,
Trying to find a good video recording app for our kindergarten, ideally one that will have a lot of various size options, videos will probably be uploaded to assorted internal and external systems and sent to parents, so need to be easy to use and support various resolutions and good selection of codecs so we can make relatively small video files but also long ones. Ideally a free app without too much creepy monitoring, but paid is an option if it is good. (though I suspect it'll mostly be used to upload to facebook and sent by e-mail or their internal e-learning platform)
The phones used in the kindergarten are primary Samsung Galaxy S6s and Sony xperia Compact Z5 and Compact X, running Android 5.x/6.x if memory serves.
(I hope that was technical enough a description, I know very little about video encoding).
In advance, many thanks.
