I've been using Vegas for a lot of years. I never recall having any problems when the product belonged to Sony. But over the years, Magix Vegas seemed to get a little better. However, VP23 is the complete opposite.
I can edit a video for 5 hours without a hiccup. Then suddenly, it will just freeze up, and I will keep having problems. Rendering? Either I can or I can't. I can try to render my project 3 times, Vegas will crash at different portions of the render process. I can try again, and BOOM, it will fully render. I can't imagine anyone using this software in a professional broadcasting capacity would be happy with it.
I know it's new, but I can't imagine, if anyone tested this, that it passed without any issues. This software was not ready for release and should have been held back until it was ready. What good is a faster rendering engine if you can't actually render?
Sorry if I'm stepping on any toes here, but I have just had enough with 23.
