Automatically Generate a Time-Lapse Video given A Directory of Images

This function generates and saves the time-lapse video based on a list of paths to the images.

plantcv.visualize.time_lapse_video(img_list, out_filename='./time_lapse_video.mp4', fps=29.97, display=True)

returns frame_size

  • Parameters:

    • list_img - List of paths to the images to create the video.
    • out_filename - Name of file to save the generated video to.
    • fps - Frame rate (frames per second) By default fps=29.97. Commonly used values: 23.98, 24, 25, 29.97, 30, 50, 59.94, 60
    • display - if True (default), displays the path to the generated video.

  • Context:

    • Used to generate time-lapse video given a list of images.
    • List of image paths can be generated with plantcv.io.read_dataset.

  • Example Use:

    • Below
from plantcv import plantcv as pcv
# Note you will have to change this part on your own path
img_directory = './path_to_images_directory/'
img_paths_list = pcv.io.read_dataset(source_path=img_directory, sort=True)

fps = 29.97
name_video = './eg_time_lapse'
display    = True

frame_size = pcv.visualize.time_lapse_video(img_list=img_paths_list,
                                                    out_filename=name_video,
                                                    fps=fps, display=display)
