What programs make animated videos for Instagram Stories?

Question

Video processing

Hey!
In what programs today is it relevant and most appropriate to make short commercial videos for Instagram stories?
Some do it in a few clicks in some applications right on the phone.
Some bother with Adobe Effects. But it's pretty complicated. it needs a bunch of plugins, + Encoder just to make a video in MP4?
For example, make an animation from a photoshop banner in layers - is it in Effects itself?
Is it possible to impose musical accompaniment in this program and is it intended for this at all?
Then in the stories of the author of the track is it necessary to indicate?

Answer 1

If something is confusing, then the effects; if it’s easy, then the built-in editor on the mobile behind the eyes

Answer 2

After Effects - from the word effects. If it's just a banal cut - it's not needed. If you have animations - you need it.
Is it possible to impose musical accompaniment in this program and is it intended for this at all?
It is possible, but it is for graphics.
Then in the stories of the author of the track is it necessary to indicate?
It already depends on copyright
