Function Details

Class local: timelapse(title, fps, folder_path, inspect=True):

xxxxxxxxxx
timelapse(title, fps, folder_path, inspect=True):
Function constructs time-lapse video from images in a folder.
        Inputs:     title   (string)     video title + .avi
                    fps     (double)     time-lapse video frames per second 
                    folder_path    (raw string)    location of the image folder
                    inspect    (boolean)       True (default)/False
        Output:
                    time-lapse video

Class memory: savebuff(frame, container):

xxxxxxxxxx
savebuff(frame, container):
Function saves image in in-memory location
         Inputs:    frame   (matplotlib image)  
                    container   (list)     empty image container
         Output:    container   (list)      image container with added frame location

construct(container, title, fps, inspect=True):

xxxxxxxxxx
construct(container, title, fps, inspect=True):
Function constructs video from images in the container.
         Inputs:    container   (list)      image container with frame location
                    title   (string)     video title + .avi
                    fps     (double)     time-lapse video frames per second 
                    inspect    (boolean)       True (default)/False
         Output:
                    video

Use Imvideo

1. Time-lapse video from a image folder:

​x
import imvideo as imv
​
imv.local.timelapse('demo.avi', 5,  r".\tests\test_image"))

2. Time-lapse video from a matplotlib loop:

xxxxxxxxxx
import imvideo as imv
​
def test_matplot_loop(n):
    ''' Input:      n   number of frames'''
    images = []     # empty image container
    plt.figure()    
    for i in range(n):
        plt.plot([np.random.randint(2), np.random.randint(2)])
        plt.title("test" + str(i))
        images = imv.memory.savebuff(plt, images)      # save image in in-memory location
        plt.close()
    
    imv.memory.construct(images, 'matplot_demo.avi', 5)        # construct video; 5 fps
​
    return 
​
test_matplot_loop(100)      # construct a demo video with 100 frames
