Video transcoding: Taking the raw uploaded video and re-encoding it so it is appropriate for being sent to video players over the web. Typically this takes the form of creating "renditions" of the source video at lower resolutions, but you'll have to decode and re-encode the video to do that, hence transcoding. Pretty much all video you watch online is delivered using an adaptive bitrate technology like HLS or DASH. That's what allows the video to automatically reduce its resolution if your network can't handle streaming the video without buffering.
