# Script to download all the WWDC 21 session videos in the highest 1440p video and audio
# You may have to update ffmpeg before using this script. I needed version 4.3 or higher to successfully download the videos.
#
# If you want the lower bitrate audio, do a find/replace of "audio_english_192" with "audio_english_64"
# If you want lower bitrate or lower resolution video, do a find/replace of "hvc_1440p_8100" with any of the following:
# "hvc_2160p_11600"
# "hvc_1440p_8100"
# "hvc_1080p_5800"
