In file-based playout, video servers are used to ingest, manage, store and playout video assets. Modern workflows cater to multi-channel subtitling and captioning, often in multi-languages and across a variety of platforms such as mobile phone and the internet.

In these modern workflows original content is repurposed using a variety of formats and is often edited to suit local cultures. Repurposing content therefore often means that there is a need to encode and transcode the subtitling and captioning data to ensure a seamless integration.

Softel has developed Swift™ vTX, a subtitle and caption software for encoding, transcoding and inserting subtitles, captions and ancillary data on video server assets. Softel Swift vTX enables the repurposing of video content regardless of file format to facilitate multiplatform and worldwide distribution and can switch between SD and HD effortlessly.
