Download thumbnail frames from a video's progress bar

thumbframes_dl

Download thumbnail frames from a video's progress bar.

When you watch a video on the web, you've probably noticed these thumbnail sized preview frames that are shown when you hover the cursor over the video player's progress bar.

When you download the actual images, you'll see that they're actually concatenated in grids containing n*m frames like this:

I refer to this individual frames as thumbframes because I couldn't find a better, less confusing name.

How to use

Install the library:

pip install thumbframes-dl

A simple example:

# Download a video's thumbframes images and save them in the filesystem
# Spring | Blender Animation Studio | CC BY 4.0
from thumbframes_dl import YouTubeFrames


# create YouTubeFrames object containing the methods to get the thumbframes
video = YouTubeFrames('https://www.youtube.com/watch?v=WhWc3b3KhnY')

# iterate all images with thumbframes (there may be more than one)
for i, frames_image in enumerate(video.get_thumbframes()):
    file_content = frames_image.get_image()
    with open(f"{video.video_id}_{i}.{frames_image.mime_type}", "wb") as f:
        f.write(file_content)  # save each image
