# Ignore any errors that occur while downloading. Occasionally they will happen and this just ensures things keep moving along as intended. Don't worry, the next time it is ran any videos that didn't fully download will most likely be picked right back up where it left off!

# These just embed metadata into the video once it's done downloading. You never know when this will come in handy, and having it all right in the video's container is nice. Just a little note, at the time of writing this post, ffmpeg can't embed images into a mkv, but the image is still downloaded and stored in the same location and with the same name as the video.

# This will filter videos out that you don't want to download. Here is just a basic example of filtering out playlists with the title "Liked Videos" and "Favorites". I find this especially useful for filtering out playlists that contain a bunch of videos from other playlists.
