B4A is intended to be extended with libraries.

I haven't watched all the videos. Can you post the actual time where the desired effect is demonstrated?

The first one can more or less easily be implemented without libs as is seems to be only a matter of repositioning views upon gesture...

The second one in part has the same effect as above but also the fading of the image.

I would then say, yes you can, do them without libraries... Or by creating your own custom view

4 rows of code.. it's simple

private Sub MyScroll_ScrollChanged(Position As Int)
    Dim Pos As Int = Max(MyTitleFull.Height-Position,MyTitleReduce.Height)
    MyScroll.Top=Pos
    MyTitleFull.Top=Pos-MyTitleFull.Height
   ' MyTitleReduced si under MyTitleFull
    If Pos=MyTitleReduce.Height Then
        MyTitleFull.SetVisibleAnimated(1000,False)
    Else
        MyTitleFull.SetVisibleAnimated(400,True)
    End If

End Sub
