使用MoviePy时文件已存在却触发FileNotFoundError问题求助

问题说明 #

运行MoviePy脚本生成图片视频时，出现FileNotFoundError，但报错指向的图片文件实际存在于指定子目录中。

原代码 #

from moviepy.editor import *
import os

Pictures = []

Path = 'Pictures_To_Use'

#Adding Pics to the Pictures arrray
for pics in os.listdir(Path):
    clips = ImageClip(pics).set_duration(5)
    Pictures.append(Path + "/" + pics)
    
#UI
Title = input("Please input a title:")
print("-" * 36)
print("Title:" + Title)
print("-" * 36)
print("The Following Pictures will be Used:")
print(Pictures)
print("-" * 36)

#Export video
video = concatenate_videoclips(clips, method="compose")
video.write_videofile(Title, fps=30)

已尝试方法 #

• 将文件路径添加到数组中
• 遍历图片数组设置图片时长
  以上方案均无效

问题根源及修正方案 #

问题点： #

1. 路径错误：os.listdir(Path)返回的是子目录下的文件名，直接传给ImageClip(pics)会让程序在当前脚本目录找文件，而非Pictures_To_Use子目录，导致路径错误。
2. 变量覆盖：循环中clips变量每次被新的ImageClip覆盖，最后仅保留最后一张图片的剪辑，且存储路径的Pictures数组未被用于生成剪辑。
3. 拼接参数错误：concatenate_videoclips需要传入剪辑数组，而非单个剪辑对象。
4. 导出文件名缺失后缀：直接用输入的Title作为导出文件名，可能导致系统无法识别视频格式。

修正后的代码 #

from moviepy.editor import *
import os

# 存储所有图片剪辑的数组
image_clips = []
image_path = 'Pictures_To_Use'

# 遍历子目录，生成完整路径并创建ImageClip
for pic_name in os.listdir(image_path):
    # 拼接完整文件路径（兼容Windows/Linux路径分隔符）
    full_path = os.path.join(image_path, pic_name)
    # 创建5秒时长的图片剪辑
    clip = ImageClip(full_path).set_duration(5)
    image_clips.append(clip)
    
# UI交互
title = input("请输入视频标题：")
# 自动添加.mp4后缀，确保视频格式可识别
output_file = f"{title}.mp4"

print("-" * 36)
print(f"标题：{title}")
print("-" * 36)
print("将使用以下图片：")
# 打印所有图片的完整路径，方便验证
for clip in image_clips:
    print(clip.filename)
print("-" * 36)

# 拼接所有图片剪辑
video = concatenate_videoclips(image_clips, method="compose")
# 导出视频
video.write_videofile(output_file, fps=30)
