Closed Caption in Premiere 2.0
Posted by Fred Williams on December 4, 2009 at 2:39 amHi all,
one question:
i’m editing video that already has closed caption data embedded in it, and i’m using Premiere Pro 2.0.
Would premiere 2.0 remove the caption data, or does the edited video still have the original caption data?
thanks for any info on this…

December 6, 2009 at 10:42 pmWhat format are you working with? HD? SD? DV? Mixed?
If you are working with HD or any 720×480 SD format (DV, MPEG-2, etc.), then no, the captions will not be preserved (unless special measures are taken).
If you’ve got 720×486 full raster SD with line 21 closed captions (white dots flashing at the top of the frame), then the captions will stay there as you edit, with the following limitations:
1) Any filters, transitions, motion effects, etc. which alter the line 21 data will damage or delete the captions from that segment.
2) You will lose the captions for about 3-5 seconds before and after each cut or altered segment.
3) The captions can go back out to tape but will not be preserved if you output your sequence to another video format, DVD, etc.
To get around the above issues, you can use closed captioning software or a service to extract the original captions and create captions for whatever output formats you need to deliver in. For more information, click the link in my sig.
Hope this helps,

December 10, 2009 at 2:11 amHi Jason, thanks for your reply,
I have video on dv tapes (that was originally transferred from beta-sp) that has captions in it, when I capture into Premiere via firewire and playback from the timeline I don’t see the flashing white bars at the top of the video on my video monitor (I have it set to under-scan to see the caption flashes). i see the flashes if i hook up my video monitor directly to the dv deck, but not when it shows the output from Premiere.
I’m using a Matrox based x2 editing system so it captures as a matrox dv format. But i can’t change the video to 720×486 it’s set only to 720×480.
do you have furthur advice on how i can capture the footage into Premiere and still maintain the caption data?
does it only work if i capture via analog input (s-video/composite) or it should work with firewire?
thanks…
