This is something that has been bugging me for years. Every version of Vegas I have used since 2009.
In a clip like the video below where there is some camera bounce shake - in this instance I was basically shooting at 900mm - but if I try to stabilize within Vegas Pro with the built in Vegas Pro stabilizations (many version over the years) or Prodad Mercalli, I can never get it to stabilize the entire scene. They always seem to end up latching onto a head in the middle of the screen, and following the head and even rotations of the head (I know how to turn that part off). It gives a very unwanted effect. I just want the clip to be completely still.
I tried messing around with motion tracking and latching onto something in the background but don't know how to get that to apply to camera stabilization. I tried the dropdown menu and setting it to the Vegas Video Stabilization - but nothing happens. I am sure this is user error (I hope) and there is a way to do this correctly within Vegas.
In After Effects I can track motion on something in the background then hit stabilize motion and it is magically rock solid (I can crop in the black edges after the fact). The problem is I end up rendering to insanely huge uncompressed AVI files then re-rendering again in Vegas pro to XAVC-I to save space. This also results in multiple separate files of sections I stabilize for a few seconds at a time. Projects get messy and there are WAY too many steps compared to if I could just ONE TIME get the same result with my tools within Vegas Pro.
Also I don't know jack crap about Adobe software other than how to stabilize a clip like I stated above, and I like the Media Encoder for easily preparing my files for web and client delivery. (if Vegas has something like Media Encoder that I am unaware of - I would love to know - but that is not the purpose of this post).
