vhs.py

Analog videotape emulator, written in Python

Examples

How it works?

Here's a simplified explanation of how the code works:

1. The chrominance and luminance signals are separated
2. Chrominance and luminance channels are compressed and processed separately.
3. The images are re-assembled

Usage

UI

Change the parameters to your liking, then hit record to tape, select the file you want to record, and wait until the process ends. NOTE: the output video doesn't have sound, so it needs to be added after the effect is applied.

Code

from vhs import VHS
...
vhs = new VHS(lumaCompressionRate, lumaNoiseSigma, lumaNoiseMean, chromaCompressionRate, chromaNoiseIntensity, verticalBlur,horizontalBlur, borderSize)
#optional
vhs.generation = 3

Installation

1. clone this repo
2. run pip install requirements.txt
3. run python index.py to open UI interface
