使用OpenCV (Python)将2张图片写入视频，时长为10秒

import cv2
import numpy as np

fps = 30  # 帧率
duration = 10  # 视频时长（秒）
total_frames = fps * duration  # 总帧数

image1 = cv2.imread('image1.jpg')
image2 = cv2.imread('image2.jpg')

frame_width, frame_height = image1.shape[1], image1.shape[0]

video_writer = cv2.VideoWriter('output.mp4', cv2.VideoWriter_fourcc(*'mp4v'), fps, (frame_width, frame_height))

for frame_count in range(total_frames):
    progress = frame_count / total_frames  # 计算进度（0-1之间）
    current_image = cv2.addWeighted(image1, 1 - progress, image2, progress, 0)  # 根据进度混合两张图片
    video_writer.write(current_image)  # 写入当前帧到视频文件

video_writer.release()
