tp is a command line tool to generate (afterimage) time-lapse video from a sequence of jpg images.
It generates uncompressed AVI files. Compression is usually required as a post-processing step by selecting an appropriate codec. Any Video Converter is available as a free software.

All you need to prepare is a jpg images and a configuration file!

• Brightness adjustment and deflicker of jpg files must have been carried out beforehand. LRTimelapse can be used for this.
• Comment out (#) is valid in the configuration file.
• In normal mode (mode: 0), alpha and threshold need not be specified. If specified, it is ignored.

input_folder=/path/to/input/
output_file=/path/to/output/movie.avi
fps=24.0           # frame per second
mode=0             # 0: normal, 1: afterimage
threshold=20       # Specifies the brightness threshold of the pixel to be synthesized in comparison brightness synthesis
alpha=1.0          # Specifies the afterimage level
