I've been using Vegas since it was Sony owned and up to version 20. I've spent money having to upgrade along the way. Each new version seemed to have new bugs. The latest bug discovered was after not using it for a little while, firing it up and finding it wouldn't open and did nothing, so had to Google and download a fix to get it working again (something to do with online validation). Just par for the course with Vegas.
Performance has never improved, and random crashes have been something to live with with all versions.
On starting a new Vegas project recently after getting a new camera I've just become more confused about project settings and dealing with 10 bit full-range footage along with V-Log. I've also found that effects and transitions seem limited compared to all the fun things I've become used to seeing online in videos on YouTube. So I decided to try something new in the form of Davinci Resolve and take the hit on learning a new package to see if things could be better.
Wow, what a difference. Yes there is a learning curve, but nowhere as steep as Vegas. Following tutorials and I'm finding colour grading much easier with much better results. V-Log and full-range footage is handled automatically and I no longer need to add Studio to computer levels or vice versa or wonder why my output has suddenly shifted from one to the other. The colour managed project settings has V-Log footage automatically recognized and transformed, and I can see lots of fun to be had following online tutorials for all sorts of brilliant effects I didn't think was possible using software at home. The user interface is more modern and intuitive and it performs much better.
The biggest differences, 1) it hasn't crashed once in using it! Vegas would always crash at least once per session if not more, but Resolve has been rock solid. 2) It's free, getting most of the functionality of the paid version. 3) Upgrading to Studio gives the owner a lifetime of updates, no more having to pay to upgrade because MAGIX has decided to increment the main version number and stop fixing bugs on prior versions. 4) Many more tutorials online for Resolve and its used professionally for many top block busting films and TV programs and dramas.
Sorry MAGIX, but I'm never coming back and wish I jumped shipped ages ago, but just felt 'better the devil you know' and I didn't want to start learning how to use a whole new editor, how many others think the same?
