视频剪辑什么鬼？Python 带你高效创作短视频

阅读更多关于视频剪辑什么鬼？Python 带你高效创作短视频

近两年，抖音、快手将短视频推到风口浪尖上，要生产出高质量的视频，离不开视频剪辑这一环节；在全民剪片浪潮中，大众使用最多的剪辑软件如：Pr、FCPX、剪印、Vue 等。视频剪辑过程中，Python 一些比较实用的技能，帮助我们更快地进行短视频的创作。！ 1、提取背景音乐和修改音量先从抖音上下载视频文件，然后利用 moviepy 依赖库提取到背景音乐。 def get_audio_from_video(video_path): """ 从视频中提取音频 :param video: :return: """ file_path = './source/' + gene_random() + '.wav' video = VideoFileClip(video_path) audio = video.audio audio.write_audiofile(file_path) return file_path 一个短视频中，可能包含多个背景音乐，需要对背景音乐的音量进行调整。 def handle_bgm(bgm_path, coefficient): music = AudioFileClip(bgm_path) # 音量调整为原来音量的倍数 out_music = music.fx(afx.volumex, coefficient).fx(afx.audio_fadein, 0

Python批量合并处理B站视频

源程序可直接到博主github上下载： https://github.com/HuerFu/bilibiliVideoMerge 　　最近想学习后端，又不想花钱，怎么办呢？于是在手机端B站(哔哩哔哩)上面找到了满意的免费视频教程，但是手机端看起来很不方便啊。于是，我通过在手机端缓存下来后，导入到了电脑端，但是我后面了发现两个问题：　　1.本来一集视频按理说一段吧，但是B站下载下来的视频并不是完整的一段，而是被分成了多段blv格式的视频，所以需要想办法把它们拼接成完整的一段视频！　　　　2.视频数量太大，不可能一个一个去修改，得想办法批量处理！（我这里有120个视频文件夹，下图所示，没显示完）　　　　基于上述两个问题，必须用一种方法快速解决！网上百度查了一些资料，觉得可行性很大，于是准备自己动手写代码来实现这一功能。人生苦短，我学Python！哈哈，就是Python没错了，话不多说，直接上自己用python写的批量合并并转换B站视频格式的源代码： # 批量合并特定文件夹下的视频文件，然后输出到指定文件夹下 # 主要是需要moviepy这个库 from moviepy.editor import * import os from natsort import natsorted import json # psutil是一个跨平台库能够轻松实现获取系统运行的进程和系统利用率

问题 I want to resize a video clip in python 2.7. For example we give "movie.mp4" with 1080p quality The result should be "movie.mp4" with 360p quality I Think that there should be solutions with Moviepy. If you know a solution with it. I would be grateful if you answer me. 回答1: Here is how you resize a movie with moviepy: see the mpviepy doc here import moviepy.editor as mp clip = mp.VideoFileClip("movie.mp4") clip_resized = clip.resize(height=360) # make the height 360px ( According to moviePy

Moviepy's ImageSequenceClip() reads PNGs wrongly like 0, 10, 100 instead of traditional counting

阅读更多关于 Moviepy's ImageSequenceClip() reads PNGs wrongly like 0, 10, 100 instead of traditional counting

问题 So I have this for-loop that creates a photo of each earthquake and names them earthquake0, earthquake1, earthquake2, and so on. plt.savefig("exports\earthquake{0}.png".format(i)) To convert these images to GIF, I use this image_list='exports' my_clip = ImageSequenceClip(image_list, fps=0.75) my_clip.write_gif('eqph_gif.gif') However, ImageSequenceClip() reads the files like earthquake0.png, earthquake10.png, earthquake100.png. How do I make my code read the photos traditionally like 0, 1, 2,

Rotate an image around its x-axis

阅读更多关于 Rotate an image around its x-axis

问题 I need to rotate an image around its x-axis (or y-axis). I can easily create such an animation with avisynth, but now I need to implement that effect with Python's moviepy module. I can easily rotate an image with the following script but need some clues how to rotate it in 2D or 3D. from moviepy.editor import * clip = ImageClip('my_image.jpg') rotated_clip = (clip.add_mask() .fx(vfx.resize, width=300, height=300) .fx(vfx.rotate, lambda t: 90*t, expand=False) .set_duration(5)) final_clip =
