Transcode Video

Hi eveyone, I have 2 questions regarding the price. I saw that for every monthly subscription choice there is always “Transcoding” included. I would like to know if :

  1. this is an automatic feature when I upload videos ? That is, every time I upload a video automatically transcode is done ?
  2. if for example (for Develop plan) I upload 180 minutes of video the first month, then the second month I upload 50 min of video, the second month I always pay $29 or $29 + $6 for going over 200 minutes of transcode
