So, apparently someone has decided to delete the Dropbox files for tutorials for new feature of Vegas Pro 19 and 20. Whether it was a video or a PDF-in-progress, they've all been removed from Dropbox.
The Pro 18 manual is still available for downloading (a whopping 592 pages!) and there's one good on-line youtube tutorial by a third-party for Pro 18, but it seems like Support doesn't care to provide PDFs etc for the latest versions of Vegas Pro 19 & 20.
My friend just ordered the software yesterday (27 June 2023), but his works environment does not allow Internet Access for security reasons. How is he supposed to access ANY video tutorials? I can send him the link to the Pro 18 manual, and he can get someone at his work to print it out, but beyond that.... he's up a creek, isn't he?
His setup: Brand-new Dell XPS Desktop, with best set-up recommendations to run Vegas Pro 20; Windows 11 Pro; 27'' Dell monitor; etc, 2 TB SSD and 2 TB HDD, intel i9, etc.
