  • Select gameplay video as background from library
  • Write youtube title, description, tags

Configuration

You need to specify your OpenAI API-Key in secrets.json according to secrets template.json.

You can configure alot of settings in config/configuration.json. The most important ones:

• output_dir to specify where your finished videos are saved. Each finished video will have its own directory containing the video file, the thumbnail aswell as text documents for the video description, tags and title.
• background_videos_dir to specify the folder containing background videos. This folder should have subfolders for each Youtube-Channel where your background video is from. There should also be a file called channel_urls.json that has urls to the background videos creators Youtube channels.

You can also specify font settings, some moviepy settings aswell as OpenAI prompts and models here.
