Thank you so much for your explanation! I've always wondered how they did that. Do you know any way to get a copy of the full video? I like to play video at 1.

Thank you so much for your explanation! I've always wondered how they did that. Do you know any way to get a copy of the full video? I like to play video at 1.5x speed, but some player don't have this feature so I need to obtain the URI (to play the network file with local player ove) or the file itself (e.g with youtube-dl).
