I have always enjoyed Vegas tried to switch to Premiere Pro but the layout of Vegas and the timeline and editing capabilities are unbeatable. Problem is that Vegas crashes a lot on my end. Even the Vegas 19 hasn't improved on that section. Especially if I have a loaded project with lots of videos and transitions it takes forever. I know you need more hardware/software info about this but I think it has to do with the plugins that I am using. The only thing I can share is that I use both high end PC and Laptop (now I am using an HP Victus AMD 5800H 32GB Ram + 3060GTX) as I have to travel.
So I will target my question only about the plugins.
Does plugins affect the speed and stability of Vegas ?
I have been using the S_Blurmocurves a lot
and the Red Giant Universe which I have seen major performance impact once I run some plugins.
I just wish Vegas had these abilities implemented (motion blur, shutter angle, matching X/Y, better subtitle and titles FX ) so I do not need to use any plugins at all.
For me I find the titles and text outdated (who is using "FLOAT and POP" in their edits?) This could be in video edit of the 90's.
Bring us a new and modern LOWER thirds option. More fonts, motion blur with a single click (like After Effects)
I also find the color corrector FX really weak. It should be updated like the Adobe Premiere lumetri is easy and gives great results out of the box. There are sliders that you can easily fix highlights, shadows. The new color grading system was a small upgrade as it makes things more complicated and does not give the same results. Also why you cannot PREVIEW the look of LUTS that you are applying for in a small thumbnail?
