The short of it. The stabilization options work in the preview. They aren't applied when I render a video. They were working for the first few videos I rendered.
The longer version.
I've only been using Vegas Pro 15 for a few days, but I am familiar with previous versions.
I haven't really edited for a few years and so am just getting myself familiar again, trying out things to make the editing I want to do more streamlined.
I was stabilizing some 4k footage shot on my phone with Mercalli v4. Trying to see how useful I can make it. Everything was perfectly fine, the results were excellent for the first few videos. However now it won't apply the stabilization when I render a video. Any video. Even ones I had previously rendered stabilized. Opened from the saved projects of those videos.
I have no idea why, I can't think of any setting I have changed. The video is stabilized in the preview before I render.
The videos are just panning or still shots of landscape. I believe the plug-in still is affecting the render. There will tend to be a jump in cropping during the videos.
There may be some setting somewhere. The stabilization also does not render using Vegas Stabilization and Boris Optical Stabilisation. I don't recall editing any settings. I've tried different project settings and render settings, all have the same problem.
