MediaMate

Convert | Manipulate | Analyse | Extract

MediaMate is a flexible software system to encode, repurpose and/or decode subtitles and captions in a wide range of file-based workflows.

It suits applications for TV broadcasters and playout centres, media service facilities and operators of VOD, mobile, IPTV and web-video services – anywhere that media files need to be created or converted quickly, simply and automatically.

Workflows

Standard packages cover the most common workflows, each incorporates one or more pre-configured workflow models to suit particular applications (see datasheet for details). These packages can be combined to support more complex workflows or a custom package can be prepared on request, combining components from multiple models or adding additional functionality.

MediaMate Single & Multi Insert – encodes teletext/OP47 and SCTE-27 subtitles and EIA608/708 closed captions into MXF, MPEG-2 I-frame only tall SD video (e.g. D10, IMX50) or DVB Transport Stream files
MediaMate Open Subtitle Encoder – creates subtitles as image sequences for applications such as Cinecanvas and Blu-ray authoring and for 3rd party compositor systems (e.g. Vantage, Rhozet and Final Cut Pro) or for direct encoding into a MPEG-2 I-frame only media file*
MediaMate WebText – converts standard subtitle file to various text/XML formats typically used for subtitling of Internet media (e.g. TTML, SMPTE-TT, FF, NetflixTT, ITT, Web-VTT, SMIL and SRT)
MediaMate Subtitle Extract – extracts teletext/OP47 subtitle or EIA608/708 closed caption data from a media file (MXF with SMPTE436M datatrack or GXF with RIFF, MPEG-2 SD video with VBI data, or DVB transport stream file with teletext subtitles)
MediaMate Screener – produces an open-subtitled WMV from media file and corresponding subtitle file, ideal for approvals/preview
MediaMate Subtitle Analysis – checks subtitle files for a range of errors and inconsistencies (see below)
MediaMate File Converter – converts between subtitle file formats
MediaMate Retiming– frame rate conversion, EDL to remove and/or retime subtitles, PAC to/from SCC conversion
MediaMate Audio Description Mixing (new) – creates a “broadcaster mixed” audio description track with dipped programme sound during narrations, using a standard audio description WAV file (with control/warble track for pan & fade) and associated broadcast programme audio WAV
MediaMate TTS (new) – converts subtitle files into audio WAV files using Text-To-Speech technology (via standard Microsoft Speech API), for audio description or spoken subtitles
Input Subtitle File Formats – Supported input subtitle file formats include: PAC/FPC, STL, CHK, EBU-TT, 890, SRT, SUB, OVR, TXT, XIF, CAP with SCC supported for EIA608/708 closed caption insertion

* for long-GOP, H264 etc – we recommend the Vantage Plug-In integration to add quality open subtitles to the widest possible range of media formats

System Integration

MediaMate can be used as a standalone application (using watch folders) or controlled via a third-party system such as a workflow management package.

Standalone (Watch Folders) – When launching the MediaMate Shell as a standalone application the user loads a previously configured workflow model that includes input and output watch folder paths as well as the detail of the particular workflow process.

Command line – MediaMate Shell can also be invoked from a command line or desktop shortcut, to include a standard/generic workflow model and its session-specific configuration (via an XMLCFG file).

Rest API – MediaMate includes a web interface allowing a partner application to control and configure the system using standard HTTP POST and GET methods in a ‘REST’ style, that includes commands to control the running and configuration of MediaMate workflow models, and to report on their status and progress.

MediaMate DLL – for a tighter integration a vendor system can integrate with the MediaMate DLL via a bespoke Agent interface to pass information between the two systems.

Telestream Vantage

MediaMate can be used standalone or fully integrated into a Vantage workflow. When used in this way, a MediaMate component within Vantage is inserted into to workflow and used to configure the parameters that are automatically passed to a MediaMate instance when it is called by any Vantage node (MediaMate must be installed on a Vantage node for the integration to work). A Screen Agent / MediaMate Connector licence option (which must be purchased from Telestream) is required to support this functionality. MediaMate workflows for EIA 608/708 closed captioning, MPEG-2 insertion, WMV Screener and Subtitle Analysis are not currently fully integrated into Vantage.

Automated File QC

The MediaMate Subtitle QC module performs the following series of automated checks to validate a subtitle file:

CHARACTER COUNT – Counts the number of characters per row.
ROW COUNT – Count the number of rows in the file.
ROW BOUNDING – Check that subtitle rows fall within allowed ranges.
TIMECODE VALIDATE – Check for valid (legal) timecode values for subtitle InCue and OutCue.
TIMECODE OUT OF RANGE – Check for out of range values (ie not before SOM or after EOM).
NEGATIVE DURATION – Check out-time timecode is later than in-time value.
SEQUENTIAL TIMECODES – Check all timecodes are in ascending order.
SUBTITLE MIN DURATION – Check if subtitle duration is less than the minimum allowed.
SUBTITLE MAX DURATION – Check if subtitle duration is greater than the maximum allowed.
SUBTITLE INTERVAL – Check if interval between successive subtitles is greater than the minimum gap allowed.
SOM CHECK – Compare user set Start of Media timecode (SOM) and the received SOM from the subtitle file.
ITALICS CHECK – Report an error if subtitles contain Italics when they are not desired.
“STORY” CHECK – Compare subtitle file name and STORY value in subtitle zero
LANGUAGE CHECK – Compare the subtitle language in the filename and the LANG value in subtitle zero.

Output is XML saved to a configured location. Alternatively a custom workflow may include email failure notification and/or XLST to client XML format.
