Sony HD Deck Settings

Sample XDCAM HD (1080i) MXF file with Closed Captions

XDCAM HD MXF files can be generated by the Sony XDCAM HD deck and through a non-linear editing system like Avid or Final Cut Pro with the free Sony Transfer tool.

MacCaption-HD Enterprise can then add captions directly to the MXF file without any rendering or recompression of the video or audio essence data.

To print to an HDCAM (SR) or XDCAM HD deck via HD-SDI from Final Cut Pro, please see the Matrox MXO2, Blackmagic or AJA closed captioning workflows.

Sony XDCAM EX and HDV decks currently do not support HD closed captioning.

MXF Closed Captioning Workflow

1. First, you need to start with a Sony XDCAM MXF file.  This file can be copied from a Sony XDCAM HD deck, or generated by the Sony XDCAM Transfer Tool plug-in for Final Cut Pro, or generated by newer Avid systems or some compression programs.
2. To generate a proxy movie for use in your caption preparation, you can optionally use the Sony XDCAM Transfer Tool for Final Cut Pro to re-wrap the MXF file into a QuickTime movie for playback.  This QuickTime is used only as a reference for the captioner to prepare the captions, so it is not strictly necessary if you already have a proxy movie or a completed timed & formatted caption file.
   Note: When importing this file, please set the MacCaption movie time to start at 00:00:00:00.  The captions should be timed such that 00:00:00:00 aligns with the first frame of the MXF file, even if it has a different embedded starting time code.
3. In MacCaption-HD Enterprise, once the captions are ready, go to File > Export > HD > Material Exchange Format (.mxf).
4. Select the name of the new MXF file to save.
5. In the next window, select the original MXF file that contains the source video & audio in XDCAM format.
6. MacCaption will export a new MXF file, containing the original video/audio data unchanged (no recompression), plus the closed captions.  This file can then be copied to an XDCAM disc, or to other systems which support Sony XDCAM MXF files with closed captions.

Sony HD Deck Settings

To record an HD-SDI signal with closed captions, your HDCAM (SR) or XDCAM HD deck must be configured to record closed caption packets on VANC Line 9, DID 61, SDID 01.  We have the settings for some Sony decks posted below.  If your deck is not listed or you have any questions about configuring your Sony deck, please contact Sony directly for assistance.
