How do I down-convert HD video with captions to SD without losing the captions?
Only a few hardware devices (such as the Matrox MXO2 and the AJA FS-1) can preserve the closed captioning when down/up-converting a video. For other devices, you must use a separate workflow or separate output step to create the SD video with closed captions. For example, if you have a HD sequence in FCP, you can render this into a SD sequence and then use the SD captioning workflow. Or, you can print to SD tape (taking advantage of hardware down-convert), then capture SD back in and caption it using the SD workflow. See the AJA / Blackmagic / Matrox workflow pages for more info. 11. My Sony HD deck won’t record HD video with closed captions. By default, most Sony HD decks are factory set to not record VANC Line 9 where the HD closed captions are stored. You must go into the deck setup or maintenance menu and look for the “VANC Packet RX” setting. This should be set to: VANC Line 9, DID 61, SDID 01. The exact menu depends on your deck.
