How is this video editor (sale or not) compared to DaVinci Resolve, Davinci Studio, or Wondershare.

What are the positive and negative sides of this editor, in your opinion?

How can I make the videos upload faster? They take awhile, It used to upload somewhat fast and idk how to fix that little issue.

After the last update I no longer see my audio waves, I see the clips now, that is cool, but I relied on the waves. It showed the gaps and especially in multiplayer games I could see when the other one was talking and the audio needed to be adjusted. I've tried several settings, clicked the button show waves several times, nothing! I want it back. It was the whole reason I used this....

i want to remove the background of a video and replace it with a green screen so i can use it as a meme format or something
