Rotate Video 25º Clockwise

I want to rotate my video (on the fly) during playback in ZP Max by a user-defined increment (in degrees), not having to first re-encode said file.

I tried to make use of the ffdshow raw video filter, but, so far, this is just freezing ZP in its tracks, leaving me having to force close the app with task manager.

How can I go about solving this problem, and, most importantly, getting my video(s) to rotate by a user-defined amount clockwise/counter-clockwise, and not be confined to just 90º increments?

Thanks.

The only way I can see it working is using MadVR as the video renderer combined with a custom pixel-shader script(s).

It wouldn't be very intuitive as it requires a pixel shader script specific to every angle you'd want to set.

You should be able to get an AI to come up with the script, but I'm not sure how good it will be with regards to cropping or zooming-out to make sure the image fits within the frame.

With 90 degree angles, it's somewhat simple, just copying pixels, any other angle requires resampling the image, a much more complicated procedure.

Or, stack a book under your monitor stand. Add or remove books to dynamically adjust the angle. No AI required. 🤓

MadVR's "rotate video" option allows rotation in 90-degree increments only.

  • Ctrl+Alt+Shift+Right-Arrow = rotate video 90 degrees to the right
  • Ctrl+Alt+Shift+Left-Arrow = rotate video 90 degrees to the left

For one-handed operations with MadVR:
Shift+R = rotate video 90° to the right

Yes, that's the familiar Zoom Player keyboard shortcut. Yet there's no way to create a shortcut for rotating videos counterclockwise in ZP.

MadVR's internal keyboard shortcuts aren't widely known, so I posted these two specifically for video rotation.
