Thumbnail Generator

This is a Python application that can be used to generate video thumbnail for mp4 and mkv file types.

Installation

You can use pip:

~$ pip3 install thumb-gen

Configurations

(These may change during the update)

  • The number of screen images that should be included in the final thumbnail image

  • Thumbnail image quality

  • Font type in the video info panel. You can add a file path of a font file (.ttf) to this

  • Font size in the video info panel

  • Custom text in the video info panel

Download font files : FontSquirrel

~$ thumb-gen -c

or

~$ thumb-gen --config

By program default:

IMAGES = 12
IMAGE_QUALITY = 80
FONT = 
FONT_SIZE = 30
CUSTOM_TEXT =

Usage

Usage options

-h, --help      show this help message and exit

-c, --config    Configurations

-v, --version   show program's version number and exit

-f, --file      input a single video

-d, --dir       input videos from a directory

Console

~$ thumb-gen -h
~$ thumb-gen --help

~$ thumb-gen -c
~$ thumb-gen --config

~$ thumb-gen -v
~$ thumb-gen --version

~$ thumb-gen -f input.mp4
~$ thumb-gen --file input.mp4
~$ thumb-gen --file "d:/videos/input.mp4"

~$ thumb-gen -d videos
~$ thumb-gen --dir videos
~$ thumb-gen --dir "d:/videos"

Python

  • If you don't set an output folder, thumbnail images will be saved in the video folder (video_path).
  • If you don't need a custom text and custom font file (including font size) and you have already set these for the configuration file (using console or defaults), it will be added automatically. To avoid this set the custom_text value to False and add a custom font file location.

Example 1

from thumb_gen.worker import Generator

#video_path, output_path='', custom_text=True, font_dir='', font_size=
app = Generator("C:/input/video.mp4", "C:/output/", "www.example.com", "C:/Windows/Fonts/Arial.ttf", 30)
app.run()

Example 2

import os
from thumb_gen.worker import Generator

folder = 'C:/input'
for video in os.listdir(folder):
    if video.endswith('.mp4') or video.endswith('.mkv'):
        app = Generator(os.path.join(folder, video), custom_text=False, font_dir="C:/Project/font.ttf", font_size=25)
        app.run()
