At the 2015 NAB Show, Telestream will demo support for new formats, closed captions, multibit-rate encoding, and multitrack audio in Episode 6.5, the latest version of its multiformat video encoding software.
Episode 6.5 enables caption insertion with encoding and pass-through options, and supports CEA-608 and CEA-708 closed captioning standards as well as MCC and SCC caption formats. The aim is to enable postproduction workflows to handle embedded captions easily in the face of federal regulations. The new version also accommodates additional video and audio formats, including HEVC, XAVC, VP9, and MXF AS-11.
In terms of multi-bit-rate streaming, Episode 6.5 makes it possible to encode and create packages for Apple HLS (HTTP Live Streaming), Microsoft Smooth Streaming, and MPEG-DASH with one click in order to deliver videos in the resolution and bit rate that best match viewers’ connection speeds.
Telestream has added presets and filters to Episode 6.5 so that users can map multitrack audio channels — i.e., rearrange audio tracks, change speaker assignments, and change audio formats and sample rates.
Finally, image sequences are now available directly from the Episode UI, which the company says provides an easy way to manage thousands of frames for 3D animation and compositing for visual effects.
