COOKERY

Requires imagemagick.

Video support requires FFMPEG.

required args:

• -f image_file (default: spongebob.jpg)

You can also always add the image file as the last argument without -f

optional args:

• -n iterations (default: 10)
• -s save every (default: 1)
• -h history file output (default: history.txt)
• -r file to replay (default: null)
  • must be a history file that resulted from cooking
  • -n and -h arguments will be ignored
• -o output_directory (default: output)
• -l only generate last image (default: false. just include -l to turn on)
  • -n argument will be ignored

Usage:

./cook.sh -n 10 -o output_folder -s 1 -f spongebob.jpg

By default, cooking steps will be saved to history.txt. T save elsewhere, use -h [filename]. All history is also appended to scratch.txt as a backup in case a good sequence gets lost. To replay a history file, supply it with the -r flag.

To replay a history file:

./cook.sh -r history.txt -o output_folder -f spongebob.jpg

COOK A VIDEO

The cook-video.sh script requires a .mp4 file and a history file generated while cooking an image. You can also optionally provide a framerate. The default is 30 fps. Here's how to cook a video at 60 frames per second, saving all generated files in the video-output folder:

./cook-video.sh -r history.txt -fr 60 -o video-output vid.mp4

This script generates individual frames from the video at the specified framerate, saves cooked versions of each frame following the history file into a cooked subfolder, and recombines those frames back into a video called out.mp4 in cooked.

COOKERY DIRECTOR: -d

Instead of using a single history file to cook all frames of a video, you can provide a sequence of history files and specify which frames they apply to using the Cookery Director flag, -d. This points to a Director Folder.

A director folder contains: a director.txt file, and a history subfolder. The history subfolder contains any history files referenced by the director.txt file.

The format of the director.txt file is [history file],[last frame]:

history1.txt,999
history2.txt,1000
history3.txt,2000
history4.txt

This file will apply history1.txt to frames 0-999, history2.txt to frame 1000, and history3.txt from frame 1001 to 2000, and history4.txt from 2001 to the very last frame.

./cook-video.sh -d ./director -fr 60 -o video-output vid.mp4

Hot tip: to see how many frames are in a video, use the -fc flag:

./cook-video.sh -fc vid.mp4
total frames: 150

COMMANDER MODE

Cory's power user cooking scripts. Make unique directories for each export, and sort handling of the history file ;-)

output=$(date +"%d-%m-%Y-%H-%M-%S"); mkdir $output;./cook.sh -n 10 -o $output -f spongebob.jpg; cp history.txt $output; rm history.txt

output=$(date +"%d-%m-%Y-%H-%M-%S"); mkdir $output; ./cook-video.sh -r history.txt -o $output vid.mp4; cp history.txt $output
