if you're looking for professional-level video editing on AOS4, i'm afraid it doesn't exist. that said for basic editing there is
videoclipper,
videoeditor,
ffshop, and -- the one i use --
blender. blender's interface isn't the most intuitive, but i find it the most useful. if you're looking for something more useful, try ffshop.
i hope these will meet your needs, but as other amigans using AOS3, AOS4, MOS, and AROS can tell you, there aren't that many 'modern' professional video tools out there for us at this time.
