In this captivating time-lapse video,
In this captivating time-lapse video, we'll guide you through the mesmerizing process of creating stunning time-lapse footage using Python and your webcam. Experience the enchantment of time unfolding as we showcase a fascinating walking water experiment, where water magically transfers from one glass to another through tissue paper.
We will walk you through the entire process, from setting up the necessary Python libraries to capturing frames using your webcam and compiling them into a stunning time-lapse video. You don't need any prior programming experience to follow along, as we'll provide the code and explain each step in detail.
In this tutorial, you'll learn:
How to install the required Python library (OpenCV) for webcam integration
How to save frames as individual images for later use
How to compile the captured frames into a time-lapse video using Python
We'll also demonstrate an intriguing walking water experiment, showcasing the mesmerizing transfer of water between glasses through tissue paper. This engaging example will add an extra element of fascination to your time-lapse video creation journey.
The code provided will serve as a valuable resource for both beginners and experienced Python enthusiasts. Feel free to modify and experiment with the code to create your own unique time-lapse videos.
Unlock the power of Python and unleash your creativity by joining us on this exhilarating journey of time-lapse video creation, complete with a captivating walking water experiment. Subscribe to our channel to stay tuned for more exciting tutorials and coding adventures.
Code:
take pictures via webcam
import cv2 #pip install opencv-python
import time
import os
def capture_webcam_image(output_directory):
Initialize webcam
cap = cv2.VideoCapture(0)
Check if the webcam is opened correctly
if not cap.isOpened():
print("Failed to open webcam")
return
Find the next available image number
image_number = 1
while True:
output_path = f"{output_directory}/webcam_image_{image_number}.jpg"
if not os.path.exists(output_path):
break
image_number += 1
Capture and save image
ret, frame = cap.read()
if ret:
cv2.imwrite(output_path, frame)
print(f"Image saved as {output_path}")
Release the webcam
cap.release()
Set the output directory for the images
output_directory = "/path/to/save/images"
Set the interval between captures (in seconds)
capture_interval = 300 # 5 minutes
while True:
Capture and save image from webcam
capture_webcam_image(output_directory)
Wait for the specified interval
time.sleep(capture_interval)
#convert to video
import cv2
import os
def create_video_from_images(output_directory, output_video_path):
Number of frames per second in the output video
output_fps = 30
Create the video writer object
fourcc = cv2.VideoWriter_fourcc(*"mp4v")
output_video = cv2.VideoWriter(output_video_path, fourcc, output_fps, (640, 480))
Convert saved images to video
for i in range(1, len(os.listdir(output_directory)) + 1):
filename = "webcam_image_" + str(i) + ".jpg"
if os.path.exists(filename):
image_path = os.path.join(output_directory, filename)
frame = cv2.imread(image_path)
output_video.write(frame)
Release the video writer
output_video.release()
print(f"Video saved as {output_video_path}")
Set the output directory for the images
output_directory = "/path/to/save/images"
Set the output video path
output_video_path = "output_video.mp4"
Convert saved images to video
create_video_from_images(output_directory, output_video_path)
