Ask HN: Which small video editor do you use?

When creating product videos, I'm looking for a very simple video editor, preferably in the browser, that can work with layers:

  - add video from a MP4
  - add text
  - add stickers (à la GIPHY)
  - render as MP4

I've tried this:

  - TikTok video editor, perfect, but only works on mobile (not available on PC), and anyway I can't export the finished video as MP4
  - TikTok Ad video editor, working on PC, but I can't export as MP4
  - Veed.io, kapwing.com, clipchamp, ... are ok, but they all have expensive pricing: at least 12$/mo for no watermark

Are there open source solutions? Or paid software with a one-time payment?

(I don't like to spend 15$/mo for this: it will be 540$ spent in 3 years! I prefer software with a one time payement, 50 or 100$)
