好的，以下是Python代码实现进度条加载的功能：

import cv2
import numpy as np

# 视频分辨率
VIDEO_WIDTH = 1920
VIDEO_HEIGHT = 1080

# 进度条属性
BAR_WIDTH = int(VIDEO_WIDTH * 0.8)
BAR_HEIGHT = int(VIDEO_HEIGHT * 0.1)
BAR_COLOR = (255, 255, 255)
BACKGROUND_COLOR = (0, 0, 0)

# 加载字体
font = cv2.FONT_HERSHEY_SIMPLEX
font_scale = 2
font_thickness = 5

# 创建视频输出对象
fourcc = cv2.VideoWriter_fourcc(*'mp4v')
video_writer = cv2.VideoWriter("E:/Template/word/progress_bar.mp4", fourcc, 25, (VIDEO_WIDTH, VIDEO_HEIGHT))

# 循环生成帧并写入视频文件
for i in range(101):
    # 创建画布
    canvas = np.zeros((VIDEO_HEIGHT, VIDEO_WIDTH, 3), dtype=np.uint8)
    canvas[:] = BACKGROUND_COLOR
    
    # 添加进度条
    x = int((VIDEO_WIDTH - BAR_WIDTH) / 2)
    y = int((VIDEO_HEIGHT - BAR_HEIGHT) / 2)
    progress = int(i * BAR_WIDTH / 100)
    cv2.rectangle(canvas, (x, y), (x + progress, y + BAR_HEIGHT), BAR_COLOR, -1)
    
    # 添加进度文本
    text = "Progress: {}%".format(i)
    text_size = cv2.getTextSize(text, font, font_scale, font_thickness)[0]
    text_x = int((VIDEO_WIDTH - text_size[0]) / 2)
    text_y = int(y - text_size[1])
    cv2.putText(canvas, text, (text_x, text_y), font, font_scale, BAR_COLOR, font_thickness, cv2.LINE_AA)
    
    # 写入视频文件
    video_writer.write(canvas)
    
# 释放资源
video_writer.release()

该代码使用Python的OpenCV库，创建了一个黑色背景的画布，并在画布上添加了一个进度条和进度文本。然后它循环生成帧，并将每一帧写入视频文件中。在每一帧中，它会更新进度条的长度和进度文本的内容。最后，视频将保存在指定目录下。
