OBS Extrapolation pans a scene in response to video data in the OBS capture

Saccade is a weird OBS Python script that is weird

Saccade attempts to make video recordings of perspective / widescreen games display more salient information when packed into portrait-form content. It can do this in real-time for streaming.

It is primarily based on https://github.com/upgradeQ/OBS-Studio-Python-Scripting-Cheatsheet-obspython-Examples-of-API/blob/master/src/get_source_frame_data_ffi.py

It works! It applies smoothed proportional control correlated with scene motion and some other hacky control stuff that could use some tuning.

It badly needs to be refactored and it also crashes when you go to close OBS and after streaming for a while usually.

It depends on Python, OBS, Numpy, OpenCV and will require some expertise or patience to get setup.

Install Instructions

⚠ This software is free-of-charge without any warranty.

Install Python

Grab Python portable and install it in your root directory

Install Deps

Use a pip bootstrap to grab:

• cd C:\PythonPortable
• $gp = wget https://bootstrap.pypa.io/get-pip.py
• echo $gp.Content > get-pip.py
• notepad.exe get-pip.py (Save as ANSI)
• .\python.exe get-pip.py
• .\python.exe -m pip install opencv-python
• .\python.exe -m pip install opencv-contrib-python

Install OBS

Install OBS Inside of Tools > Scripts go to Python tab Point to C:\PythonPortable

Make a scene

Default name for the Source is "Spaceship" Create a source named "Spaceship" It probably has to be less than 1920x1080, for reasons Make your Canvas portrait Center and vertically-fit your source to the canvas Add _saccade.py as a script

Other stuff

There's a bunch of hard-coded variables at the top of the script, stuff like Canvas geometry, framerate, and panning strength are tweakable.

I don't know, good luck.
