save videos with a loop

slobzheninov

Hi! I’m trying to save multiple mp4s with a loop, but each next video contains all the previous + the current one. Sort of like 0, 0+1, 0+1+2, etc.

Could you please help, I’m probably missing something obvious? Should I reset the saveImage somehow?

Here’s a test code:

W, H = 500, 500
FRAMES = 5
fps = 5

outputs = 3
for output in range(outputs):
    
    for frame in range(FRAMES):
        newPage(W, H)
        frameDuration(1/fps)
        fill(1/(output+1))
        rect(0, 0, W, H)
    
    saveImage("~/Desktop/test-%s.mp4" % output)

Thank you!

you will need to reset the drawing stack with newDrawing() after you exported a video

see https://www.drawbot.com/content/canvas/pages.html#drawBot.newDrawing

W, H = 500, 500
FRAMES = 5
fps = 5

outputs = 3
for output in range(outputs):
    
    newDrawing()

    for frame in range(FRAMES):
        newPage(W, H)
        frameDuration(1/fps)
        fill(1/(output+1))
        rect(0, 0, W, H)
    
    saveImage("~/Desktop/test-%s.mp4" % output)
