I have been tempted to purchase an upgrade from Vegas 18 to Vegas Edit 21 but would like to know what to expect. Hoping it will do a better job when editing my GoPro 11 4K video (HEVC H.265). Since my last post I have added an NVidia RTX 3060 graphics card. The addition of the card did not seem to make much difference while editing. Unchecking "Use Legacy HEVC" helped a great deal before I got the card but now I still get some stuttering when previewing. Some have advised to stop trying to use HEVC and to convert my videos before editing using Handbrake or Shutter Encoder. Thought Vegas 21 might eliminate that need. Here is my current system specs along with a screenshot of the File I/O in prefs.
i9-13900K
32GB RAM
Windows 11 Pro
2GB M.2 for C drive
NVidia RTX 3060 (new)
Currently using Vegas Pro 18.0 Build 527
Many thanks for any advice/help!
