MoviePy - Text with moving Letters

MoviePy - Text with moving Letters

Creating an animation where the letters of a text move individually can be done using MoviePy by creating a clip for each letter and then composing them together. You'll need to use the TextClip class to create text clips and then animate them using the set_position method with a lambda function that changes their position over time.

First, you need to install MoviePy if you haven't already:

pip install moviepy

Here is a simple example of how you might create an animation with MoviePy where each letter of a word moves independently:

from moviepy.editor import TextClip, CompositeVideoClip, VideoClip # Duration of the clip duration = 5 # Create a clip for each letter letters = "MoviePy" clips = [] for i, letter in enumerate(letters): # Create a TextClip for each letter txt_clip = ( TextClip(letter, fontsize=70, color='white') .set_duration(duration) .set_position(lambda t, i=i: (100 + i*60, 100 + i*10*t)) # Moving position .set_start(0.5*i) ) # Start 0.5 second later for each letter clips.append(txt_clip) # Generate a background clip (you can customize this) background = VideoClip(lambda t: (255, 255, 255), duration=duration).set_duration(duration) # Overlay the text clips on the background video = CompositeVideoClip([background] + clips, size=(960, 540)) # Write the result to a file video.write_videofile("moving_letters.mp4", fps=24)

In this example:

  • TextClip is used to create a clip for each letter.
  • set_position is given a lambda function that changes the position over time, creating a moving effect.
  • set_start delays the start of each letter's animation to create a staggered effect.
  • CompositeVideoClip is used to combine all the text clips onto a solid white background created by VideoClip.
  • Finally, we write the result to a file moving_letters.mp4.

Adjust the fontsize, color, and set_position lambda function as needed to get the desired visual effect for your specific case. The lambda function for set_position should return the x and y coordinates of the letter at time t. The example above moves each letter downwards over time with a start delay, but you can customize the motion as you wish.
