HDS and closed captioning

Hey there,
Does anyone know if CC is supported in a standardized form?
From what I gathered, there seems to be support for a text track in the fragments sent over HTTP, but there is no mention of the correct format and usage of the text data,. Is the text track used for closed captioning (by standard, using a TTML or simialr format) or is it a 'free text' track, which can be interpreted by the HDS player at any way?
If CC is not supported by the official standard, are there any players (e.g. OSMF, Strobe) which support it, even by using plaugins?
Thanks.

There is support for both inline and external CC. Look at the ClosedCaptioning plugin for OSMF to enable CC through external TTML files. That's in the OSMF repo. Look for the OSMFCCDecoder for inline CC. It's included in AMS installs. But it is much harder to set up to test.

Text caption in hidden not exported (export /project captions and closed captions)

If you have in your demonstration text caption (ballooons) in
hidden , if you export the project caption to word it's not in
there...
I use to set some text captions to hidden to ease my life on
slides that contain lots of ballons (and some over other ones) ,
when I export the flash animation, everything is fine , all is in
there (including the "hidden text") .
The trouble is that if i export the "project caption and
closed caption" to Word , the text of captions in hidden is not in
there . (I'm not talking about exporting handsout where you have an
option to export as well hidden slides.)
Exept if I'm wrong, I have not founded any option to manage
the fact to export hidden caption as well (or set all hidden
caption of the demonstration to "not hidden") .
It is really a problem , especially if you have done lots of
movie that needs translation, you have sent the "exported caption"
to the translation service and now you realise that some parts are
missing .... ;(

Hi There,
When you export the doc file as Project Caption and Closed Caption. if you change the fonts and style in Doc file and the reimported it in Captivate. It will accept those changes and you can see those changes in Captivate with the same fonts settings.

Error by exporting Captivate to Word: "Project Captions and Closed Captions"

Hello everybody,
I'm from Germany, working in Heidelberg and I've got a problem! I would so much appreciate if somebody would have a solution for it.
Nobody could help me yet - no Adobe support via chat, no Adobe support via phone. They said the forum is my last chance. I'm frustrated. But a solution is important for my ongoing project...
Description of the problem situation:
I've created an e-learning project in German language. This e-learning shall be translated into other languages, so I want to export a word document with the captions inside. I'm doing this way:
File > Export > Project Captions and Closed Captions, and save it as word doc.
But then, after I typed in a name for the word document, another "Save as"-window appears in the background (I discovered it by coincidence) and wants me to save a word template before the export process starts. Here's a screenshot:
I don't know the reason for this second "Save as" window, so I try to save a word template (I saved it on my desktop, because I don't know where else).
After klicking on "Save" the following error message appears:
(in English: Error by exporting of captions. Try the following things: if Microsoft Word is installed, if Word is open, if the exported file is open etc.)
It's not depending on the captivate file as such, I tried it with other ones (which have only one slide) - the same problem.
It's not depending on my computer, I tried it with another one in my office - there was the same thing, same error message (but without the step of saving a word template!).
Maybe important: My hardware and versions I'm working with...
Windows 7 Professional (Service Pack 1), 64bit
Adobe Captivate 8
Microsoft Word 2010
Does anyone has the same problem or does anyone know the answer for this problem?
I would really really appreciate your answers!! Thank you in advance!
Chris

Dear Mayank, dear Lilybiri,
thank you both soooo much, I couldn't belive what I saw as the export of captions worked!!! It was really surprising!
I guess your both solutions helped me out - Mayank's hint of the admin's rights was the necessary information! But it first worked because Lilybiri told me to insist and to try it after I restarted the PC - and to do it several times! So it worked!! Otherwise I would probably still be confused.
Thank you so much!
Here's the proof
Chris
PS: Does anyone know, why I still have to decide if I want to save the "Adobe Captivate" Template thing?
Every time I'm doing an export it asks me every time if I want to save or not save the "Adobe Captivate"-file...

CP8 Interactions and slides with audio and closed captions - not working well - please help

Okay, I am using cp8 on a windows 8 64 bit machine. I have placed an interaction on a slide. I also have audio on that slide and closed captions.
When I get to the slide, the audio does not play because the mere fact that the interaction is on there makes the slide pause upon enter. I could have the student click play on the playbar to go, but that is not required on slides without interactions, so I don't like that solution. I also could do an On Enter slide Play Audio and pick the wav file, but then the closed captions don't show up.
So, the question is, how do I have the slide automatically play the audio at the slide level without the student having to click the play button to go?? Slides with interactions should behave just like other slides with objects/widgets on them. This auto pausing thing is driving me nuts!
Thanks,
Lori

Lori, this is puzzling! Are you talking about one of the learning interactions included with Captivate? If yes, which one? My puzzlement is due to the fact that what you described is what happened in CP6: interaction paused slide at first frame (I had a workaround for audio). But since CP7 interactions do not pause any slide, you'll have to provide the pause yourself. There are some exceptions (games).

Importing swf file with skin and closed captioning problems

I created a flv file in Preimere and I pulled it into flash to create close captioning. When I publish it, it creates a swf file that I can open up on its own and it has the skin with the button to push to show the closed caption. When I try to bring that file into captivate, it doesnt bring in the skin and it just automatically shows the captions. How do I get it to bring the skin in with it?

Are you seeing this problem when you preview you project. or only after you publish it? If it is when you publish, is it in both the local version and/or in the web version?
Also, which version of Flash Catalyst? 1.0 or 5.5.?

TV@nywhere and closed captioning?

Is it possible to get closed captioning through S-video?
It's been a while since i used this tuner. I used it for a while till i installed an ATI all-in-wonder.
Now i am back with a different video card and back to the TV@nywhere. I remember being able to get CC with the TV@nywhere but i cant seem to get it to work now.
I'm using DirecTV connected through S-video with WinDVR3. The close caption option is greyed out.
I am also using the latest driver from MSI's website.
Is it becuase i'm using S-video? Does closed caption only work with coax (gross)?
Thanks

I don't want to seem dense but the only thing I see available from their web site is drivers. I have the drivers installed that came on the CD with the MSI TV@nywhere Plus tuner card that I just bought. What is the "MSIPVS software from MSI's website". Do I need other drivers, if so, which ones.
Thanks

Language selection and closed captioning

hi! i'm using adobe captivate 5 and i'm wondering if i can implement language selection for the narration in my presentation and at the same time have closed caption with it.
like, i could choose english for the audio and caption then later choose i.e. german.
thanks!

I don't think you could do this in the same lesson without a lot of fancy AS3 widgetry underneath the hood. It would not be easy.
Your quickest and easiest way to implement such an idea is simply to have two versions of your course, one with English and the other in German, Then you have a landing page that offers the learner the option (clickbox or button) to select their preferred language. Clicking one or the other will branch them to open the relevant lesson.
Where you may encounter problems with this is when you are using an LMS. If you have both English and German lessons packaged together in the same course, the LMS will think the learner has only completed half of the total lessons. In that case, you are forced to have two entirely different courses packaged as an English SCORM and a German SCORM. The user would then be selecting their preferred language in the LMS, not in the Captivate lesson.

CP5 and Closed Captioning

How can I adjust the timing of the CC? I would like to move some to match the audio better.
I had hoped I could change the timing on the slide audio window but can't see how.
Thank you,
Susuan

Hi,
After you have added closed captions to slides, go to 'closed caption dialog'. You can reach here by following shortcut "ctrl-alt-c" or by using menu item Audio > Edit > Slide" and select tab "closed captioning"
On top of the waveform, you will see black colored markers. Click and drag these markers to adjust the timings of every closed caption created on that slide. Changes in timing by dragging of marker is reflected in the timings mentioned below for every closed captions.
Hope this helps.
regards,
Mukul

Netflix and Closed Captioning

Is there a way to turn on Closed Captioning in Netflix when using the AppleTV? I have a PS3 that I use for Hulu Plus, but I use my AppleTV for Netflix. The PS3 has the option of turning on Closed Captioning, but I can't find any such option for the AppleTV. If there is one, can you point me to it? Not the closed Captioning for Apple's rentals. I really don't want to use the PS3 for Netflix, but I feel I almost have to because of this issue.

To turn on CC and subtitles:
Go to Settings -> Audio & Video -> Subtitle Language to turn off or select the language of choice for subtitles
In Audio & Video -> Closed Captioning to turn on or off CC.
Most movies in the Apple store do not have CC. All movies in Netflix do not have CC or subtitles on the ATV2 but only on the PC/Mac and one of the game consoles I read have an add-on to get it to work. I have heard nothing on when the CC or subtitles will be ported to the ATV2.
Hope that helps

Flash and closed-captioning

How is the closed-captioning handled on the sample
success
story about Sony's use of Flash?
Thanks.

Nickels55,

figure
> out. If you use captivate you can sync captions with
audio.
I haven't used Captivate, but I've heard of this approach
quite often.
Sooner or later, I ought to check it out. :)
> Walter's idea is the way to go though, but that way is
all
> manual labor...
Respectfully, I disagree. Closed captioning is manual labor,
period
(well, unless Captivate assists the workflow). Someone's got
to listen to
the audio and painstakingly transcribe the dialog, in
addition to noting the
timing of phrases. In my experience, this is easiest to
handle in XML.
Then ActionScript parses that XML, assigns cue points to the
video by way
of, say, the FLVPlayback Component, and listens for the
cuePoint event.
These events can trigger peripheral animation, pause and
advance the
timeline (etc.) and display closed captions. If the FLA needs
to change, no
problem. If the frame rate of either the FLV or the SWF needs
to change, no
problem. If a spelling mistake is discovered that ripples
through the whole
scription ... no problem. If the text formatting changes
throughout, no
problem.
In addition, the FLV -- especially one of the length shown
-- simply
shouldn't be imported directly into a FLA. It would make the
SWF at least
as large as the FLV itself, which might be dozens of
megabytes. Instead,
load the FLV at runtime. It starts playing almost
immediately, the SWF is
small, and you have all the benefits described above for the
captions.

Movies in the right format and closed caption

As you know, movies in iTunes are not formatted to be watched using a regular TV Screen, but rather to be watched using ipod. As a result, the quality of the picture of movies purchased in iTunes but watched on AppleTV in a regular TV is very poor, rather awful indeed. Can you tell me when are you planning to sell High definition Movies, or at least a higher picture quality format, in iTunes?
Also, isn't it a federal requirement to have closed captions in movies that are presented on TV for the hearing impaired? When are you planning to closed captioned your movies? Thank you

As you know, movies in iTunes are not formatted to be watched using a regular TV Screen, but rather to be watched using ipod. As a result, the quality of the picture of movies purchased in iTunes but watched on AppleTV in a regular TV is very poor, rather awful indeed.Strange. I have no problem watching them on a 42" plasma screen. My only complaint is with my oldest "Baseline" rofile (320 x 240) files which I created at half the recommended dvideo data rate to save storage space on my iPod. Even then, these files are "viewable" if not up to the minimum standards demanded by some users. In this case the answer is obvisou -- don't buy or use the product if it doesn't measure up to your espectations.
Can you tell me when are you planning to sell High definition Movies, or at least a higher picture quality format, in iTunes?The manner of your question seems to imply that you consided this forum to be an Apple Corporate area for direct communication between employees and the general public -- it isn't. We, like you, are just fellow users. While it is true that Apple owns and maintains the boards, they are for the purpose of peer-to-peer self-help.
Also, isn't it a federal requirement to have closed captions in movies that are presented on TV for the hearing impaired? When are you planning to closed captioned your movies?The best place to answer this question would be by reading the ADA regulations which are available on-line. Even if specifically covered, it would then behoove you to address your question to the party or parties resposible for creating the media in question and not the the store that sells them. While Apple may distribute the files, it does not own the copyrights for them nor have a creative say in their production. While I believe Apple is working on a hardware/software means of delivering CC when/if the studios choose to emplement such for on-line delivery. In fact, I doubt studios would actually object to such if the means were already in place to do so. Unfortunately, at this time "Open Captioning" (AKA Subtitling) is about the only means available at this time and means that all viewers would be required to watch subtitles (unless the studios should offer CC/non-CC versions). Same answer could apply to your format problem -- merely point out to the major movie studios that they should sell their products in multiple formats with and without captioning.

FCP and Closed Captions

I looked in my FCP manual and I cannot find any information on closed captioning. What I need to know is if the CC information is already recorded on my mini DV tape, then when I capture it to FCP does it retain that information? So then when I output back to tape will the CC information still be there? For an example of how this would be used... I work at a community college where our students produce a news show. While they tape the show (to mini DV) someone types the CC live and it is recorded to the mini DV tape. Since it is a student production there are sometimes mistakes. So after the show is taped a student will "post" the show in FCP before it is aired on our cable station. Right now we do not CC. But we have to start. So before they purchase equipment we need to know if this will work. Anybody know? Thanks.

I'm doing a show for a client that will run both nationally and locally. When we started they would be identical shows. We budgeted for CC. Then the client tells me he's sold three extra :30 spots for the local version. Um, okay.
So I told him to sell 2 more spots and we'll just cut one segment of the show that now has to time out to exactly 2:30 each week.
Ahhhh, first time producers.

Apple TV and Closed Captiones

I've noticed that a lot of Movies as well as TV Series are coming now with CC. When I whatch them on my Mac, no problem, the CC works as advertised.
I have not gotten it to work on my iphone, but have gotten it to work in my ipad. Yes I've veryfied that CC is turned on in settings.
What I truly want, is to be be able to watch all the TV series and movies that I buy on my apple TV. I've tried streaming (airplay) my video (confirmed that it has CC) from both my iphone and ipad to my apple TV and nothing. I've also connected both apparatus directly the the HDMI connector and nothing.
So my question is. How can I watch my CC videos purchased on iTunes on my TV?
Thanks for your wisdom.

I meant from iTunes on your computer using the computers menu on the Apple TV.
You can turn closed captioning on/off in Settings > Audio & Video

Any word about final cut pro and closed captioning?

Has anyone heard any news of Final Cut Pro dealing with the issue of closed caption for their software?

Close Captioning is done through/with DVDSP, not FCP. Not good news if you want to deliver on tape-- but great if you deliver on DVD<<</div>
Todd,
Not exactly true ... While they may seem to serve a similar function, Closed Captioning and Subtitling are two distinctly different things. Subtitles can be used on DVD-Video and turned on or off by the user via the remote (or defaulted to on by the author). Subtitles are also used by film makers releasing their films in foreign language countries.
On the other hand, Closed Captioning is encoded into line 21 of an NTSC video signal. CC is received and decoded by TV sets (required on ALL TV sets sold in the U.S.) as mandated by FCC ruling several years ago and more recently required by law under provisions of the Americans with Disabilities Act (ADA).
Since it's inception, CC inclusion was a very expensive process and remained in the realm of specialized service companies for many years. With the recent passing of the FCC's deadline for almost ALL broadcast programing (with few exceptions) to be closed-captioned, I would think/hope that NLE vendors, like Apple, Avid and others would incorporate CC capabilities into their programs. There is one other CC software solution for Macs that I'm aware of available from: http://www.ccaption.com/
