I don't know how many times Acid Pro and Vegas have let us down. Sony are great making hardware but when it comes to software they are pretty weak.
Very unreliable and unstable.
Crashes in the middle of doing very simple audio edits.
And what makes it worse is the fact that it sometimes (more than just 'sometimes' actually!) creates bad backups that will not load!!!!!
Unfortunately there is just so much of "Mr. Humpfninkel's Sales Technique" already pieced together in Sony Vegas that we can't start again in another editor.
Our initial aim was to do all the animation and video editing in Blender 3D and the cleanup and sync in Reaper - a shareware product. But Reaper is weak on it's visual capabilities. It simply cannot cope with video playback properly - which is a terrible pity because Reaper is probably the very best audio editor I've ever used. Fast, reliable and well designed.
I really wish Sony could've spent more time creating a competent editor rather than focusing on overloading their software with unnecessary frills and gimmicks.
They should take a long, hard look at Open Source software to appreciate the value of reliability and stability over cosmetics.
