If you are working with video editing or video processing tasks using Moviepy library in Python, you might encounter the need to display the timecode of a video. Timecode is a unique identifier for each frame in a video and is commonly used in film and television production.
In this blog post, we will explore how to display timecode using the Moviepy library in Python. Let’s get started!
Installing Moviepy
Before we begin, let’s make sure we have Moviepy installed. You can install Moviepy using pip
by running the following command:
pip install moviepy
Importing the necessary libraries
To display the timecode, we need to import the following libraries:
from moviepy.video.io.VideoFileClip import VideoFileClip
from moviepy.video.VideoClip import TextClip
Loading the video
To display the timecode, we first need to load the video using the VideoFileClip
class from Moviepy.
video = VideoFileClip('path/to/video.mp4')
Make sure to replace 'path/to/video.mp4'
with the actual path to your video file.
Defining the timecode function
Next, we define a function that will generate the timecode for each frame of the video. For simplicity, let’s assume that the timecode format is in HH:MM:SS:FF (hours:minutes:seconds:frame).
def timecode(current_time):
hours = current_time // 3600
minutes = (current_time % 3600) // 60
seconds = (current_time % 60) // 1
frames = int((current_time % 1) * video.fps)
return f'{hours:02}:{minutes:02}:{seconds:02}:{frames:02}'
Adding the timecode to the video
Now, we can add the timecode to the video using the TextClip
class from Moviepy. We will overlay the timecode text at the bottom right corner of the video.
video_with_timecode = video.fl(TimecodeVideoClip(video, timecode))
timecode_text = TextClip(timecode, fontsize=24, color='white',
bg_color='black', size=(150, 40)).set_position(('right', 'bottom')).set_duration(video.duration)
video_with_timecode = CompositeVideoClip([video_with_timecode, timecode_text])
Saving the video
Finally, we can save the processed video with the timecode using the write_videofile
method.
video_with_timecode.write_videofile('path/to/video_with_timecode.mp4', codec='libx264')
Make sure to replace 'path/to/video_with_timecode.mp4'
with the desired output file path.
Putting it all together
Here’s the complete code that puts everything together:
from moviepy.video.io.VideoFileClip import VideoFileClip
from moviepy.video.VideoClip import TextClip
def timecode(current_time):
hours = current_time // 3600
minutes = (current_time % 3600) // 60
seconds = (current_time % 60) // 1
frames = int((current_time % 1) * video.fps)
return f'{hours:02}:{minutes:02}:{seconds:02}:{frames:02}'
video = VideoFileClip('path/to/video.mp4')
video_with_timecode = video.fl(TimecodeVideoClip(video, timecode))
timecode_text = TextClip(timecode, fontsize=24, color='white',
bg_color='black', size=(150, 40)).set_position(('right', 'bottom')).set_duration(video.duration)
video_with_timecode = CompositeVideoClip([video_with_timecode, timecode_text])
video_with_timecode.write_videofile('path/to/video_with_timecode.mp4', codec='libx264')
