MediaMate

File-Based Subtitle Encoding, Extraction, Manipulation & Conversion

MediaMate’s suite of software solutions streamlines the process of subtitle encoding into media files, caption extraction from media files, subtitle file manipulation and format conversion to create modern workflow that improve efficiency and reduce labor intensive changes to subtitles and captions.

ENCODE | EXTRACT | CONVERT | MANIPULATE | ANALYZE

MediaMate is a flexible software solution used to encode, convert, manipulate, extract, re-purpose and/or decode subtitles and captions in a wide range of file-based workflows.

It is used by TV broadcasters, playout centers, agencies, production houses, editors and operators of VOD, mobile, IPTV and web-video services to create automated workflows to improve efficiency and modify subtitle files quickly and easily.

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 subtitle image sequences and can also add in-vision subtitles to MPEG-2 I-Frame SD Video.
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 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 program sound during narrations, using a standard audio description WAV file (with control/warble track for pan & fade) and associated broadcast program audio WAV
MediaMate TTS
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

* Please ask for details for specific workflows as results may be effected by internal processing constraints, particularly for metadata, styling, positioning, cumulative subtitles and other non-contiguous timecode sources.

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.

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 (i.e. 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 Durations
Check if subtitle duration is less than the minimum allowed.
Subtitle Max Durations
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.
