About

This program scrapes post information using PRAW.

The program performs its video manipulation using ffmpy

• downloads a video from a reddit-hosted video post
• normalizes the video dimensions to 1920x1080
• overlays top reddit comments scrolling up the left sidebar
• overlays a gif on the bottom right corner

The video dimensions are normalized to 1920x1080 to be easily combined to create a compilation later.

Top tags for each video are drawn from top comments. nltk is used to select 1-word, 2-word-phrase, and 3-word-phrase tags to represent a post. This feature works best if the post has a large number of comments.

Tested with Python 3.7.0 in Linux environment
