Worst app ive ever used!

Ive been looking for like 5 hours for an editor that wasnt glitchy and would play my videos correctly, the style of the app was very old looking, not that that matters too much but whatever, and when i went to play my video, the quality was bad, only the audio would play and i was stuck on the screen so i had to completly shut off my laptop. Not sure if this app works for other people but i certainly did not have a very nice experience with it.
