Closed Captioning using Titler…
Hi, I need to add closed captioning to 8 5 minute videos and give these files to a programmer who is making a touch panel presentation. Since these videos are not going to DVD, but to MPEG2 (computer based), I cannot use Encore’s Subtitle (or can I?) feature, so I was going to make the subtitles in premiere and output mpeg2 files. Are there standards for doing this, where should be placed on the screen, what about lower thirds, do they overlap them, do you put text over a black lower third? If anyone knows a way to do this in Encore where I would end up with an mpeg2, please let me know. Thanks.

Closed captioning generally means that the captions can be turned on or off. Is this the case or are your captions always on?
The two types of closed captions I know are 1) Those on a DVD 2) Those embedded in line 21 on an NTSC signal. The latter are turned on or off with the “caption” setting for your TV set.
To do line 21 captions you need a full NTSC signal (720×486). They will not work on 720×480.
If your captions are on all the time then it’s a non-issue. Just put your captions in as you want them in Premiere Pro and then output the file as MPEG2 from the media encoder in PP, or output the picture in whatever video format you’re using, and do the MPEG2 encoding in your favourite encoder (Procoder, Cleaner, etc.)

Norman, Thanks for the quick reply. Since this is going to be used in a touch panel kiosk, the guy who is designing the system thought it would be best to have two sets of videos, one with CC and one without. So the viewer presses the “video 1” button and then is asked if he wants CC or not and push the appropriate button to play the video.
Your workflow is PP is what I expected, but wasn’t sure about the guidelines for CC. Would I use black behind the text or just the text over the video and do they interfere with lower thirds. Thanks.

These are two completely different things. Closed Captioning is embedded in line 21 of NTSC video and has to be decoded by a CC decoder in your television. “Subtitles” or “Open captioning” is what is used in DVDs

Then Open is what I’m referring to or simulated CC.

Does anyone know if I can do this in Encore and then rename the vob file as an MPEG and thereby take advantage of the subtitles feature in Encore? Didn’t want to double post or I’d ask in the Encore forum.

You can use subtitles in Encore DVD. When you press a button on screen or perhaps on a remote, the subtitles become enabled. I would reccomend going this way, because running 2 streams of video and then syncing them just for the titles may lead to a major workflow issue.

Thanks Aanarav, but these files are not being played from a dvd player. Actually using a program called Scala. The designer of the system just wants MPEG2 or WMV or QT files, one set without subtitles and one set with. This is for a museum for touch panel monitors. Is there a way to save files in Encore as just an MPEG2? I have to trust the system designer as he has done a lot of these installations, just goes against my normal workflow. This is why I thought I would just do it premiere and make track 2, the subtitles and then export as an MPEG2. Thoughts?

Ah. Good old Scala. What version are you using? We are running a year old version, so I might be able to check it out personally. Since you have the option of using a quicktime MOV, I would reccomend purchasing Quicktime Pro for $30. Why? Because you can add subtitles right within QT Pro and then toggle the subtitle track.
Please refer to page # 36 of the Quicktime User Guide, found here: https://images.apple.com/pro/pdf/QuickTime_7_User_Guide.pdf

I’m not sure I’m going to purchase it, but the designer of the system has the latest version. I do have QT pro. I’m still not sure they want the viewer to have to do anything. they just want the subtitles to be on the screen after they choose whether they want them or not. I’ll check it out though and see if I can just have them on using QT Pro. Appreciate your replies.
