python将一张图片转视频

简介：python将一张图片转视频

python提供了两个库实现将一张图片转视频，分别是moviepy和opencv

moviepy将一张图片生成视频

def movie_video(image_path,output_path):
    '''将一张图片合成视频
    image_path：图片路径
    output_path：输出路径
    '''
    from moviepy.editor import ImageClip,ImageSequenceClip
    # 创建一个ImageClip对象，设置持续时间
    clip = ImageClip(image_path, duration=10)
    
    # 写入视频文件
    clip.write_videofile(output_path, codec='libx264',fps=30)

opencv将一张图片合成视频

def img_video(image_path,output_path):
    '''将一张图片合成视频
    image_path：图片路径
    output_path：输出路径
    '''
    import cv2,numpy as np
    # 读取图片  
    frame = cv2.imread(image_path)  
    height, width, layers = frame.shape  
    
    # 设置视频的编码器、帧率、尺寸  
    size = (width, height)  
    out = cv2.VideoWriter(output_path, cv2.VideoWriter_fourcc(*'mp4v'), 30, size)  
    
    # 假设你想要一个10秒的视频  
    duration = 10  # in seconds  
    frames_to_write = int(duration * 30)  # 帧率 * 时长  
    
    # 将同一张图片写入多次来创建视频  
    for _ in range(frames_to_write):  
        out.write(frame)  
    
    # 释放VideoWriter对象  
    out.release()
