Reddit Compilation Maker

Reddit Compilation Maker is a Python tool created to automatically create compilations from subreddits content. Can be used to synthesize the trending videos into compilations, automate content generation for social media, and much more.

Requirements

This program relies on bulk-downloader-for-reddit, which in turn needs ffmpeg to work correctly.

You also need numpy and moviepy.

Installing ffmpeg

• On Linux: run sudo apt install ffmpeg
• On Windows:
  • Download the installer from here or here and run it
  • Add ffmpeg to your Path:
    • Go to Environment Variables
    • Select Path -> Edit -> New and add C:\FFmpeg\bin (or wherever you installed ffmpeg at the previous step)
• On MacOS:
  • Install Homebrew
  • Run brew install ffmpeg

Installing numpy and moviepy

Run python -m pip install numpy moviepy

How to use

Selecting the target subreddits for your compilations

Just edit settings.py to include all the subreddits you want. To make the script more flexible, topics allows to keep track of multiple topics. This means that the final output will mix videos from all the subreddits provided for each topic.

Each topics element is a dictionary with the following format:

{
    "name": "MyTopic",
    "subreddits": [ {"name":  "first-sub", "sort": "top", "time":  "week", "limit": 10},
                    {"name": "second-sub", "sort": "hot", "time": "month", "limit": 20} ],
    "MAX_CLIP_TIME":    60.0,  # seconds
    "MAX_SUBCLIP_TIME": 20.0,  # seconds
}

In the example above, the script will generate a compilation "MyTopic" containing videos from "first-sub" and "second-sub" (add as many as you wish).

The videos will be selected by taking the first 10 and 20 posts of each subreddit, sorted by "top of the last week" in the first case and "hot in the last month" in the second case.

Videos longer than MAX_SUBCLIP_TIME will be discarded, and a single compilation won't be longer than MAX_CLIP_TIME. If the total duration of the videos is longer than MAX_CLIP_TIME, multiple compilations are generated.

Feel free to add as many compilation topics as you want by populating topics with more dictionaries in settings.py.

Running the script

Run python main.py from the command line.

Additional options

About sort and time

These options are taken from the original bulk-downloader-for-reddit repo:

• sort: accepts hot, top, new, rising, controversial and relevance
• time: accepts hour, day, week, month, year and all

Videos order inside the compilation

Note that videos are currently being sorted by order inside each compilation video. This suited my use case, but you can change it in main.py.
