¹ Fast Track indicates that the file will be playable immediately after upload. No transcoding will be necessary, however we will transcode the video to multiple proxies (SD & HD) to support varying bandwidths for better experience while playing.
² Timecode support indicates the file’s SMPTE timecode TC_IN and TC_OUT will be read and automatically applied in the Klash video player when using SMPTE timecode format in the player.
