i bought a sony vaio 7 years ago and came with adobe premiere video editing software but i never had the use to purchase the full blown version for my own purposes. about a couple of years ago, my computers hard drive crashed. replaced hard drive and i was able to recover to the factory setting and its entirety as if i had just bought the computer from 7 years ago. but when i tried editing videos again, every video transition is jittery or you can say shaking or just a real bad transition. even just on just a fade out and fade in video transition. i have uninstalled and reinstalled adobe premiere 4 times but no help. this was not like this before the hard drive crash. help me please somebody. thank you.
