I use Filmora 9. I have their lifetime membership! I signed up for their free trial but when I tried to export the video I could not upload the video without the watermark unless I purchase the software. I had spent 3 days making the video so I decided to Purchase the software. There was a discount with Filmora 9 and I also did research online and found a $5 coupon for Filmora. All in all I ended up paying around $37 including tax. It usually cost around $80 USD for their Lifetime membership. The also have a yearly subscription if you don't want to purchase the lifetime. My subscription came with a free trial of Filmstocks for one month. I don't regret the decision to purchase Filmora 9 since it is so easy to use (faster learning curve compared to other editing software) and way cheaper compared to other editing software options out there. Other people use Davinci Resolve the free version but I haven't try it myself yet. I hope this helps!
Depends on your computer. DaVinci is very good - and free. But you have to have a pretty new machine. Older machines will not run it. My old PC would not run it, my new one will, but I already bought PowerDirector (had it for years) so I am still using PD because I am used to it.
