  <p>I want to create clips with that format to have as overlay of other videos, so the format better has to be supported by main video editing programs.</p>

  I'm assuming that by formats you mean codecs. The following are codecs that work in either Quicktime (.mov), AVI, and MXF containers, or as image sequences saved as discrete files.
  
  **Commonly used in the industry:**
  
  * Apple Animation (has been around forever, 8 bit support only)
  * Apple ProRes 4444 (probably the most widely used? I have no data, just guessing)
  * Avid DNxHD & DNxHR (this could be just as widely used)
  * GoPro Cineform
  * PNG Sequence With Alpha (my favourite, allows for faster [multi-instance renders](https://blob.pureandapplied.com.au/finally-managed-to-peg-my-cpu/)), also TIFF sequences (ditto, but bigger files)
  
  **More obscure:**
  
  * Avid Meridien
  * other image sequences: Cineon DPX, Maya IFF, OpenEXR, Targa
