hello,
To extract frames from a video for analysis using Python and OpenCV, follow these steps:
import cv2
def extract_frames(video_path, save_dir):
cap = cv2.VideoCapture(video_path)
frame_count = 0
while True:
ret, frame = cap.read()
if not ret:
break
cv2.imwrite(f"{save_dir}/frame_{frame_count}.jpg", frame)
frame_count += 1
cap.release()
# Example usage
video_path = 'your_video_path.mp4'
save_dir = 'your_save_directory'
extract_frames(video_path, save_dir)
Replace 'your_video_path.mp4' with your video file path and 'your_save_directory' with the directory path where you want to save the frames. This script extracts each frame from the video and saves it as an image file, ready for analysis.
Thanks.
