Selur you are awesome. I will follow your instructions.

There is this one and its really good in the few tough cases where Stab doesn't work well and StabilizeIT zooms and move too much.

Is that something that can be implemented in Hybrid?

Quote:https://github.com/georgmartius/vid.stabThis is a 2pass process, first you run vidstabdetect and later vidstabtransform so you won't get a preview, but this is already in Hybrid. (was added in 2018.10.07.1)

You need to use 'No XSynth' and then under "Filtering->FFmpeg->Filtering->Vidstab" it's there. Personally I never really used it, but it hopefully still works as it should.
(Found a bug Filtering->FFmpeg should be disabled when 'Only use encoder' for NVEncC&co is enabled, which it is not atm. => fixed in dev Hybrid_dev_2024.11.05-192319 and newer)Cu Selur

thats a welcome surprise. Where is vidstabdetect located?
RE: Vapoursynth, Frame, Stabilize not working - Selur - 05.11.2024
You use "Filtering->FFmpeg->Filtering->Vidstab" to configure both detect and transform.

Regarding Stab under Stabilize tab. The Shift Max X/Y. If I set it to 4/4. Does that mean the range it can go 2 up, 2 down, 2 left, 2 right, so a shift a max shift of 4. Or its 4 up, 4 down, 4 left, 4 right, a max shift of 8?
RE: Vapoursynth, Frame, Stabilize not working - Selur - 02.12.2024
afaik.:
x (aka. dxmax): should be 4 pixels in each direction on the horizontal axis
y (aka. dxmay): should be 4 pixels in each direction on the vertical axis
It's important to note that these parameters limit the maximum shift that can be detected between consecutive frames. If you set them too low, you might miss larger motions in the video, while setting them too high could potentially lead to false motion detection. So depending on the amount of general motion speed and resolution, you might want to adjust the default 4.
(Stab calls DePanEstimate. https://github.com/Vapoursynth-Plugins-Gitify/DePan => https://github.com/Vapoursynth-Plugins-Gitify/DePan/blob/2f055894a75f8d261129cad1e6391c3e38eeda90/DePan/DePan.cpp#L112)
