What about iMovie?
> Now that Photos allows you to edit videos, and Big Sur expands that to allow cropping and filters, you might be wondering why you should bother with iMovie. But iMovie allows you to do a great deal more than just crop, trim and add filters. For example, iMovie has 29 themes that make it really easy to turn your photos and movies into Hollywood-style trailers. It also allows you to add transitions and fades to your videos, as well as apply picture-in-picture and green screen effects and speed up or slow down clips. It also allows you to apply image stabilisation to shaky clips, add Ken Burns-style effects to still images, adjust the colour, and apply lots of different audio and video effects to clips.
iMovie is well integrated with Photos, so it’s easy to pull in images and video clips from your Photos library, and to share them with iOS versions of iMovie. iMovie has been around on the Mac for many years and had its ups and downs, but it remains a very capable video-editing tool for anyone who needs to do more than just trim clips and add filters, but doesn’t need a professional tool like Final Cut Pro.
