slit_scanner_darkly
Slit scanning. From frames to weird final product.
This is a repository that allows for creating several types of slitscans (examples available further down the page).
Setup: 0. Install ffmpeg and Python 3
- clone this repo
cd slit_scanner_darklymkdir venvpython3 -m venv venv/source venv/bin/activatepip install -r requirements.txt
Single Slitscans: Single slitscans come in two flavors: horizontal and vertical. This style of slitscan is inspired by [Adam Magyar's Urban Flow project] (http://www.magyaradam.com/).
Moving Slitscans:
Like the single slitscans (horizontal and vertical), but compiled over all the images in a sequence. Each new frame
is a single slitscan from a different x or y coordinate.
Usage:
Required Args:
| Flags | Help |

|---|---|
| -t, --slitscan_type | Type of slitscan to be performed. [0]=single-vertical, [1]=single-horizontal [2]=Moving-Horizontal, [3]=Moving-Vertical, [4]=Moving-Both (Vertical AND Horizontal) |

Github doesn't let me embed YouTube vids... lame. I put a few gifs in, but for full examples see the videos.
