I bought vegas pro 20 because i thought that i might need to upgrade as vegas 16 has become really slow and keeps crashing amd there was no update for this program, so i bought vegas pro 20 the newest one, and ''i still have the same problem'', when editing, The preview lags and i can't edit like that, the preview is at the lowest blurry in draft and i have also tried preview half, and i shouldn't need to lower the preview as i need it to see clearly what i am doing/editing, at the lowest settings for the preview it still lags and i can't edit, also when i stop playing/previewing when editing, vegas goes white and then says its stop responding, and the program never comes back, i have manually force quit meaning i click on the x to close vegas, it then comes up with a box saying vegas has stopped, i click ok on the box and vegas closes, i also have to save my projects every 1 min because i am scared i will lose my projects i am working on becuase vegas has become the worsed editing software there is, never had a problem with cheap editing softwares before like Wondershare i am thinking about moving to adobe, i dont want to because that means i will have to learn a whole new way of editing in a different interface but magix!, your pushing me over the edge, I went from vegas pro 16 skipped 17,18,19, and went to vegas pro 20, i thought you would have fixed this issue by now, many youtubers have made videos of your software that keeps crashing all the time, its embarrassing for your company. please fix this or i am leaving your service/product forever!
