Vegas 13 has worked perfectly for me for years, first on an i7 and then when I changed my PC to an AMD Ryzen 9, still perfect. I upgraded to windows 11 and good old 13 still ran beautifully. I then added a GoPro Hero 10 to my camera bag and needed HEVC support so I upgraded to version 19. 19 crashes continually to the point that it is unusable. I decided to do a clean install of windows and reload Vegas 19 so there were no remnants of 13, but no difference, constant "not responding". So, I had to reinstall 13 but I did it without uninstalling 19 because I needed to convert the HEVC GoPro files to something 13 could handle, but I got a surprise, I could now drop the original HEVC files straight onto the 13 timeline and they play perfect! All is well for me now, I can use 13, but I'd still love to know why for me 19 is so unstable and yet 13 is so stable on the same PC? I'm obviously missing out on new features, and although it's just personal family and travel videos for myself, I still may find them useful. So, if anyone could help, I'd really appreciate it. Many Thanks, Vince
