o/ all... am trying to use Deshaker to process some aerial video clips. Am using a hexacopter and overall, am getting good results with the Deshaker filter BUT ... I cannot seem to find any way of leveling out the roll axis so that the ground plane stays horizontal. It looks like Deshaker itself doesn't really have any means of preventing roll in the video, but maybe I'm missing something. Can anyone provide some advice on another filter or some other setting that can be used with VirtualDub to keep my audience from feeling like they're sitting in a life raft out on the ocean?!! Thanks for any help you can provide! |

See Pass 2 settings -
Max. Correction: Rotation (default 5 deg, try 45 deg)
Motion Smoothness: Rotation

Thank you for the replies and the recommendation on the rotation degree and smoothness values... finally figured out what the issue was after messing with a bunch of settings. The crux of the issue wound up being the "Detect Scenes: Threshold" value. Default was 20, and since the roll effect was slower than a quick "shake", it wasn't able to detect the change in rotation in what was occurring across a 1 to 2 second timeframe. Bumped it up to 90 and it worked perfectly - horizon stays perfectly level now.
Thanks again for the help - much appreciated !! |

where do you see those settings in deshaker?
FYI turn off scene detection, also make sure for pass one, detect rotation is checked. |

I use ver 3 which improved noise rejection and better analysis. That explains it. Thanks |
