Chroma Blend

A workaround to DeepRemaster's low resolution limitation.

Since Satoshi Iizuka's DeepRemaster functions well only with small videos (432 x 320), a solution for coloring higher resolution videos is to extract the chroma from the small video and layer it over the larger-sized black and white video.

The program takes two inputs: The original black and white mp4, and the colored mp4 output from DeepRemaster. The output is a full res avi, as well as a folder of all the video frames with the color transferred over to the original black and white frames.

This illustrates what the program does for each frame.

Installation

Download the repository:

git clone https://github.com/JohannSuarez/chroma_blend.git

Once inside the chroma_blend directory, install the required dependencies:

pip install -r requirements.txt

You're good to go!

Usage

python3 chroma_blend.py [black_and_white.mp4] [colorized.mp4]

Since this program as a whole relies on two smaller modules, the modules themselves can be used as standalone programs. The modules located in the "cblend_modules" directory are:

colorizer.py - For colorizing the frames.

python3 colorizer.py [bw_image] [colorized_image]

vid2pngs.py - For splitting videos into pngs. A directory is created for the output pngs.

python3 vid2pngs.py [input_video]
