The rotate function receives as a first parameter the stars ImageClips to rotate. This is where the fun begins! As we said before, this video deserves 5 stars,Īnd since configuring them to rotate one-by-one could be very repetitive, we are going to create a function that receives a list of stars and use a for loop in a list comprehension to return the list of stars inside clips (Like weĭid with the txt_clip and sb_logo clips) and rotating them in a clockwise direction. size + VERTICAL_SPACE * 2 )) for i, star in enumerate ( stars ) ] In this case, we are going to use an image with stars to apply a rotate effect in each of them.ĬLOCKWISE_ANGLE = - 90 def rotate ( stars ): return + txt_clip. MoviePy is capable of locating and separating objects like letters or shapes in a clip. With the text and image ready there is just one thing left to implement: Rotating stars (just because this video deserves 5 stars). In this case the text is horizontally centered using the center key and has a calculated vertical space value based on the logo clip vertical size plus a constant to put some extra space. The positions are set hereĭirectly to use the sb_logo attribute size that provides a tuple of theĬlip dimensions (width, height). Setting font, color, kerning and fontsize is enough.įinally, it sets the position it will have when included in compositions, with the function set_position, it receives a tuple that contains the horizontal and vertical values. The variable txt_clip is created for use in video composition later it is a TextClip instance that receives the text to display as the first parameter. TextClip ( "Let's build together", font = "Charter-bold", color = "RoyalBlue4", kerning = 4, fontsize = 30, ). Go the root directory of your project and create a new file named python_video.py and start by adding the required libraries at the top: This sample code will help to understand some basic concepts about Python, MoviePyĪnd image processing libraries. Forįurther instructions check the readme file for this tutorial. Modules can be installed from PyPI (Python Package Index) using pip. What Do We Need?įor this tutorial, ImageMagick is required and Python 3 with pipenv to manage its dependencies. MoviePy video tools plugins like Segmenting benefit from this to locate objects and separate them. SciPy contains modules for image processing. SciPy is a library used for scientific computing and technical computing. It includes a command-line interface for executing complex image processing tasks, as well as APIs for integrating its features into software applications. ImageMagick is an open-source software suite used for editing and manipulating digital images. It can read and writeĬommon video and audio formats and be run on any platform with Python 2.7 or Video processing, and the creation of custom effects. It providesįunctions for cutting, concatenations, title insertions, video compositing, Python module for video editing (Python wrapper for FFMPEG and ImageMagick). Image and video edition in a programmatic way. You might have heard of FFMPEG or ImageMagick for This tutorial will explain how to work with multiple video segments Python gives us the upper hand in this challenge. Here is where software development comes in handy and helps automate tasks to Having a firm understanding of what the final video should look like Producing a video programmatically might not be a task developers come acrossĭaily. That would require anĮxtreme amount of time to do, create delays in the delivery of the videos,Īnd take away from an ideal user experience. Imagineįacebook manually creating millions of videos for friendship anniversaries,īirthdays and marketing campaigns for all their users. Sound fun, but if you need to generate hundreds or even thousands ofĬustomized videos daily, this does not sound like a good idea. Creating one or maybe a couple of them might even The ChallengeĬreating a customized video might sound easy, especially if tools for videoĮditing are an option. You can find the final result for this tutorial on it’s GitHub repo which is an update from the original version that uses lib to create animations. It to create and render a fully customized video with animations, text and images using Python’s MoviePy, SciPy and ImageMagick libraries. However, Python is not onlyĬapable of achieving all of this. Programming language used for data science, artificial intelligence and for When you hear about Python, you might think about the powerful interpreted
