Personally I use Vrgas Pro since version 2 before it had video. So that would be 18 years.
As an audio program initially it was on a par with pro tools. Well not exactly, but it got the job done. And at a lot more affordable price. Additionally it had innovative features and a unique approach to NLE. They brought this same functionality to Video. And at the time these approaches were not widely used. Since then, almost all NLE products use these features or some version of them.
But what not one of these video solutions have ever had was a robust and capable as well as very good sounding audio program integrated.
You had to edit your video with limited audio. And to really get into some serious audio mixing and effects you had to use something like pro tools.
Vegas changed that. At least for those who used it. It took a lot of years and upgrades for Vegas to get the attention of professional editors. But it eventually happened.
There is an old maxim about indie film production. And that is, sadly, that audio is the last consideration. It starts out on the set with poor sound recording techniques and equipment. No regard for prepping the space for recording sound, and no budget for ADR, when the inevitable issues occur on the set that render the sound unusable.
It is interesting that people want to claim Blender as an end to end solution. Without sound this is impossible.
Secondly a VSE that is light years behind even Sony Vegas Video version 3 from 2001. Not even on the map.
But purely as an animation tool, even if you just slice your shots together in VSE, and use Audacity, you have an end to end solutuon. That’s fine.
But in the video editing world this would best be described as a joke. Considering the free or cheap alternatives.
But in an animation pipeline having the VSE is an integral part of the process from animaric and lip sync to final cut. Even if you eventually edit video in an external app.
So the VSE can not be removed without another immediate solution to replace it. Even if equally primitive on first version.
So lets assume that the VSE is wrought with issues even for an animation pipeline. I have not used it in a large production yet. But I am about to. So it will be interesting to see.
I would say in this case a more simple but extensible base module be coded to replace the VSE. And that with this new base in place, functional for an animation pipeline, future development could lead to more modern features.
