Only one opencv is enough, opencv is really strong.
Precautions:
- source_path and sink_path need to be modified;
- This version supports the conversion of mov suffix to avi suffix, and the source code needs to be modified according to the actual situation;
# 目标
# 1. 拷贝视频文件并修改后缀
# 2. 修改图片的分辨率
# 3. 批量完成
import os
import cv2

sink_path = r".\data\videos"
if not os.path.exists(source_path) or not os.path.exists(sink_path):
print('Path not exit!')

videos_list = os.listdir(source_path)
for video in videos_list:
video_path = os.path.join(source_path, video)
if Path(video_path).suffix in ['.MOV', '.mov']:
# 修改后缀名
dis_video_name = video
dis_video_name = dis_video_name.replace(str(dis_video_name).split('.')[-1], 'avi')
dis_path = os.path.join(sink_path, dis_video_name)
# 进行转换
cap = cv2.VideoCapture(video_path)
success, _ = cap.read()
# 重新合成的视频在原文件夹,如果需要分开,可以修改file_n
video_writer = cv2.VideoWriter(dis_path, cv2.VideoWriter_fourcc(*'XVID'), 25, (1280, 720))
while success:
success, vid1 = cap.read()
try:
vid = cv2.resize(vid1, (1280, 720), interpolation=cv2.INTER_LINEAR) # 希望的分辨率大小可以在这里改
video_writer.write(vid)
except:
break
Others can be ignored, but you have to read the reference link:
OpenCV uses VideoWriter to create video (Python version) : This article is really well written, a class and parameters are explained very clearly.
python+opencv batch modification of video resolution : This article will talk about it The actual application is
to copy the video through python : copy the video file like reading the file
