ccConvert - Extracting and Embedding

ccConvertExtract

Extract captions from media files or other caption formats for editing

ccConvert can convert between various closed caption formats, and between closed caption standards like 608 and 708.  Drag a video file containing closed captions onto the target area, and drop it. Select the output type. Set the location for the new closed caption file. To save into the same directory as the source file, click the Input checkbox. Press the Go button. A new closed caption file will be created within the specified location.

Embed captions back into an MXF, MOV or MP4 by re-wrapping or re-encoding

ccConvert also includes command line utilities for ccExtract and ccEmbed, so that closed caption workflows can be controlled by external controllers.  This includes integrating that functionality into internal web sites.

verifyCC

verify cc

verifyCC will check and verify all supported closed caption types (MXF, MPEG, MOV, MP4, etc), including external pure CC files like SCC, MCC and AAF.  The overall formatting and each CC line/entry is checked, and any errors are displayed in the output text box.  Checks include, but are not limited to, header information, time code validity, preface, size, count and count matching, checksum, valid 708, valid 608, and many more.  The output can be saved or copied for further investigation.

ccReview

ccReview is a closed caption and video/audio file preview and output system which supports a wide variety of broadcast and post production file formats, as well as all the closed caption sources listed above. The audio and video can be displayed on the VGA/DVI screen as well as out through an AJA video board, if available. The AJA board also supports insertion of the closed captions as 608 line 21 or 708 ANC captioning.

ccReview Interface

ccReview supports all the major closed caption types as well as all major video codecs, containers, time code types, and multichannel audio with monitor pair selection.

ccreview types

Clicking on the captions button selects the caption channel to view, but all channels are decoded and saved simultaneously so switching is instantaneous and show the text that would be present if that channel had been on for the entire play.  Attributes like bold, italic and underline are respected, as are font sizing, positioning and colors.  A seek control allows quick access to any part of the file, and the captions are decoded in sync with the current video based on absolute frame or time code.

 ccReview can view the captions a number of ways:

  • playing captions embedded within the video file
  • playing sidebar MCC/SCC/AAF/STP/XML/CSV/STL/JSON/SMI/SUB/SRT/SBV/SSA/SIF/TXT/etc. captions with the same name as the main file
  • playing all supported caption/subtitle files over black, without the original video file
  • load arbitrary caption files (both broadcast and subtitle formats) over a video, for checking different languages on one file

In the case of playing a caption file standalone, the captions are automatically moved to the start of play, and the duration is set to cover the total time covered by the captions.  This makes checking the file as fast and efficient as possible.

Typical Workflows 

  • Command line automation is available for Windows, macOS 10.14: Mojave, and Linux 64
  • Command line can be driven by external application, watch/batch or web services
  • SubTitle Edit saved to SCC/SRT/STP/SSA/SIF/SBV ccConverted to AAF (Media Composer), MCC (Premiere) or re inserted into an MXF
  • MXF, GXF, LXF, MCC or AAF to SCC or a subtitle format for re-edit in SubTitle Edit 
  • Extraction of unsupported user data, SEI, h.264 captions for MacCaption/PC caption
  • Embedding different language audio and/or caption tracks to make different MXF versions for distribution
  • Pre-air checks of embedded MXF, GXF, LXF or transport stream closed captioning
  • Pre-server checks of sidebar SCC and MCC files
