Multi-platform delivery of Adaptive Bit Rate Video Streaming Utilizing Captivate Video Player

We are leveraging SCORM for our Learning Management System. In as much, we are delivering content to 7,000+ individuals using both iOS and Android/PC; as well as desktop, laptop, tablet, phablet, and smart phone. The question is this, because the internet speed and bandwidth vary we have to leverage Adaptive Bit Rate Streaming. Currently we're using Amazon Web Services Adobe Media Server to Stream our files however if we upload differing bit rates we aren't able to enter in a URL/URI/HTTP with the xml manifest file instructing the player to determine A; if the content is for iOS or Android/Microsoft and B; it's not determining a specific file, put simply whatever we upload is streamed as flash, using RTMP protocol which doesn't work with any Hand-held device because it uses flash (not available on phones) which means that we need to utilize HTTP, but it doesn't matter what I enter into captivate, the streaming service is still utilizing flash. Anyway, moving forward. Here is the solution we need and we've been asking for months now but no one seems to have any idea how to explain the limitations of captivate, or the workaround, or the proper way to leverage captivate to this purpose.
So, how, using Adobe Captivate 8, can I stream a video, using Adaptive Bit Rate Transcoding/Encoding (without using YouTube) to deliver my training to ANY device?
While the adobe media server is great there is no clear instruction on how you create one file extension/address that will link to either F4V, MPEG4, or m3u8. (HDV, HDL respectively)
Secondly, how do we get this to utilize the Adaptive Bit Rate - being that it is the sole purpose we purchased the not so inexpensive Adobe Media Server?
Need an answer to this as soon as possible as this is completely and totally killing our work flow and LMS development and frankly, the Captivate videos, tutorials, and PDF manual do little discuss this in any technical fashion. Looking forward to your response. Many thanks

I do not know much about captivate...But i will let you k now AMS perspective( I hope it adds value)
if your end users are on PC/desktop they can use Flash player and hence rtmp streaming for AMS would suffice the needs...
All you mobile users are much likely to be consuming http streaming content and hence you must use Adobe media servers HDS/HLS streaming service.
Same stream can be used for http as well as rtmp streaming...albeit in case of live stream, the http will have some delay(about 30 seconds in thedefault setup)) as compared to rtmp.
As for adaptive bit rate streaming, it can be done both on rtmp as well as http connection and they are (configuring them is) separate and independent of each other. There are sections on Adobe help on how to configure adaptive but rate streaming in Adobe media server.

Way to check stats on bit rate versions streamed?

Does anyone know if Flash Media Server has a function that allows you to see statistics on which particular streams are being delivered?
Seems like that would be a handy tool in determining which bitrates are important to continue providing, and which are superfluous, and if it's time to try encoding at higher bit rates.
Thanks,
Mike

You may like to monitor the access.00.log file to find out what streams are being delivered by FMS at what time.

How do I add a higher bit rate Video track to a completed project

I have a pretty complex, time consuming project that includes a 2hr HDV track. After completing the DVD project with chapters added to my 2hr track in DVD studio pro 3, It apeared I could fit a higher bitrate encoded track on a double layerd disc. I've encoded the project again and now want to replace my lower quality track with the higher one.
will I loose my chapter points and what happends to my sub-chapter menus that are perfect as is?
Dual Core 2.5 G5 Mac OS X (10.4.7)

First (to play safe) make a back-up copy of the DVD SP project file - ie just the frankproject.dspproj
Will I lose my chapter points and what happens to my sub-chapter menus that are perfect as is?
No you won't ...
Open your project. Import the new 2hr vision track (2hrvision_new.m2v) into DVD SP. Highlight the old vision on the timeline. Delete it. (All the chapter markers will stay put in empty space at this stage.) Drop 2hrvision_new.m2v onto V1 of the timeline. That should be it. If you don't have compression markers in your new mpeg you may have to tweak the exact positioning of the chapter markers; but if you do have compression markers the GOP boundaries will be the same and the chapter positions shouldn't move.
If you have any problems you've still got the back-up project you made earlier, and you can try over again.

How to set bit rate of audio and video

I want to set the bit rate of audio and video (48,96.128 kbps) at the time of live streaming . i m not using the flash media live encoder because i have to make it as web applicaton. can any one tell me how to set bit rate.

When you're using Flash Player to capture and encode video, your only control is Camera.setQuality():

Changing bit rate recording options...

I have a soundcard that can record 24bit, but when I open a new single track project it defaults to 16bit. I'm able to change the sample rate of the project but can't figure out how to change the bitrate. I've been all over the application and the manual. Can anyone help me out?
Thanks!

Altough I'm not 100% sure, here's what I suspect: Your soundcard is not recognized directly by CoreAudio, you use a driver and Core Audio is talking to the driver and not to the soundcard. Since Core Audio is talking to your driver, what it sees is a 32-bits device (almost every audio software is 32-bits floating these days) and not a 24-bits hardware device. Soundtrack Pro then set itself to 16-bits files because it doesn't see a 24-bits device. I use a Focusrite Saffire and since it use the CoreAudio driver, it appears as a 24-bits device so I'm able to record 24-bits files.
Now, the real question: Why Apple forces us to use their ****** AMS control panel for Soundtrack Pro instead of having audio preferences like every other DAW in the world, including their own Logic? Having access to the bit rate, the device utilized and the buffer size in a preferences window is a necessary basic thing!

Video bit rate after conversion

Hello everyone,
Im wondering, if i have a file of x format, with 50Mb video bitrate, and I convert it using compresor 4 to ProRess 422, the result will give me a video with .mov extentin with video bitrate around 120 Mb, if I convert it to Proress (LT) it will give a result of around 70Mb video bit rate.
Will the new outputs have true clean bit rate, I mean the margine btwn 50Mb and 120 or 70, will it be showed , so will the new video show a better result, or it will just show same result at 50Mb. 2nd, in case I reconvert from Proress 422 (LT) (70 Mb) to anyformat (not necessarly using cpmpressor 4) to any format havn video bit rate again 50 Mb, will the output be the same of the original 50Mb that had the x

If you are concerned about this issue, do your own tests.
Make a copy of a representative sample of your original material in ProResHQ, one in ProRes422 and one in ProResLT
Put your original in a ProRes4444 timeline in V1 and one of the copies in V2. Apply the difference matte.
Do you see anything? Do the same process for all three variants of ProRes.
Now, convert the material to your delivery format and put it back in the ProRes4444 timeline on V1 and one of the ProRes copies on V2 and apply a difference matte. Again, what do you see?
If you see a solid screen of black, there is no measurable difference between the files.
If you do see artifacts, do an A/B comparison on a good grading monitor - sometimes stuff that shows up in the difference matte can not be seen by the eye even in dedicated A/B testing.
Have fun.
x
fwiw - all ProRes varients are 10 bit codecs. They are designed to absorb a great deal of editing/compositing without degrading. This is why you want to get any material that was acquired in a long GOP, compressed format OUT of that format as soon as possible if you will be grading, compositing or doing any work beyond simple cuts.

Subtitles causing "video bit rate too high" error

At least I think they are. My media was all encoded through compressor and when the build gets to:
- Preparing Subtitles...
- Muxing VTS011.VOB
the next message is red...
- Video Bitrate Too High
- Build cancelled
- Formatting finished.

Take a look at page 70 of the PDF for bit rates on alternate angle tracks to see if that was the issue.
Also using a CBR intead of VBR has helped in some multi angle issues.
Take a look at this thread where someone had chapter marker causing issues:

How to publish multiple bit rate(MBR) live video?

I've searched quite a few threads:
http://www.developsigner.com/blog/2009/05/28/multi-bitrate-live-streaming-with-fmle-adobe- flash-media-live-encoder
http://forums.adobe.com/thread/27371
dynamicStream.addStream("livestream1",200);
dynamicStream.addStream("livestream2",400);
dynamicStream.addStream("livestream2",600);
vid.play2(dynamicStream);
But all of them are talking about playing multiple bit rate live video,
my question is how I can publish multiple bit rate live videos in the first place?

Thanks for your reply!
But I need this to be done for each web user,
so I can't require them to use FMLE themselves...

Can I tweak the bit rate for iPod video?

I am starting to produce quite a bit of iPod video for podcasting. Some of our newer pieces are up to 2 hours long and I want to cut the bit rate back so that the files aren't so large. There does not seem to be a way to tweak the m4v parameters in Final Cut Pro or Quicktime Pro. I was able to make an mp4 video file with what a I wanted. It worked in iTunes but the iPod would not recognize it. Is there anyway to tweak the bitrate when making a video for iPod?

Is there anyway to tweak the bitrate when making a video for iPod?To exercise the greatest amount of control, use MPEG Streamclip (free). The MPEG-4 iPod presets can be user modified to limit data rates as desired.
I was able to make an mp4 video file with what a I wanted. It worked in iTunes but the iPod would not recognize it.The "Movie to MPEG-4" exports are limited to the 320 x 240 "Baseline" profile (up to v1.3).
There does not seem to be a way to tweak the m4v parameters in Final Cut Pro or Quicktime Pro.The "Movie to iPod" export is adaptively pre-set for maximum "LC" (640 x 480) and "Baseline" (320 x 240) data rates. There are no manual adjustments.

Controlling output video bit rate in FCPX

I ran into a problem: I created a mp4 file with Share/Export File… (settings: Computer, H.264 Faster Encode, 1920x1080 - edited from an HD camera): its video always freezes at a definite point when played on my BD Player connected to my HDTV through HDMI (audio instead continues on the frozen image).
It seem that the issue is a sudden video bit rate pick of almost 50 Mbps while its average is around 20-30 Mbps. It is not clear to me if this freeze is caused by the BD Player or by the HDTV not being able to handle such pick.
As a test I used Compressor to control the output bit rate (settings: average 20 Mbps and pick 25 Mbps) and this seems to fix the problem. To be more certain I should do more tests, but I'm confident I found a possible solution.
I'd like to know if there is a way in FCPX to control such picks (without using Compressor), either in the Share commands (but it seems to me that they don't provide enough setting controls) or in the timeline. By watching the Video Scopes I can see a quite strong signal in the area where the output file has the bit rate pick. But I don't know any way to have a measure useful to identify them before sharing and avoid a trial and error approach...

Below the critical point...

Tried to upload a PDF instead of PNG, but no luck. The picture shows a quite standard (I'd say...) image but with highly dense graphic of Y' component in the Y'CbCr Parade (in the limits of 0-100 IRE): much more dense than most images in the rest of the movie. So I assume this might mean a higher bit rate... but it's just an assumption.
Let me summarize my tests:
1st test: FCPX: Share/Export File.. (settings: Computer, H.264 Faster Encode, 1920x1080)
- copied the .mp4 file to USB drive
- USB drive into a BD player connected to HDTV through HDMI >> freezing effect
2nd test: FCPX: Send to Compressor - Compressor: Create Blu-Ray Disk (on Hard Drive) and Video Job with standard Video settings (Automatically select bit rates = ON)
- Played the .img disk with "Mac Blu-Ray Player" on my iMac >> same freezing effect in same position as before on HDTV
3rd test: FCPX: Send to Compressor - Compressor: Create Blu-Ray Disk (on Hard Drive) and Video Job with customized Video settings: Automatically select bit rates = OFF - Average = 20 Mbps - Maximum = 25 Mbps
- Played the .img disk with "Mac Blu-Ray Player" on my iMac >> NO MORE freezing effect (and smaller file by 30%)
I might do more tests (mainly on my HDTV) but I believe the point is the bit rate... and the only way to control it is by using Compressor.
So now my question: is there a color setting that helps in controlling such situation ? e.g. lower saturation, or lower exposure, maybe in mid tones or highlights, or what ?
Thanks so much for your help

Multi-platform File Adapter

We are currently looking at the requirements for several new processes involving use of the File Adapter functionality. Our production BPM environment is RedHat Linux 4, while this particular legacy system runs on Windows 2000. The legacy system is already configured to read and write XML files into Windows file shares. Some integration processes should kick off when XML files are written to the file shares. Other processes will write XML files back into the file shares. I am looking for recommendations as to the best architectural approach to dealing with this multi-platform problem within the BPEL PM. As I see it, we have a few of options:
1.     Utilize FTP server functionality rather than direct file access to read and write the files in a platform-independent manner.
2.     Use some other technology to bridge between the platform-specific file directories and something less dependent on platform. For example, pick up the files from the Windows directory and write them to an AQ queue. Then feed the BPEL process from the queue.
3.     Run BPM on multiple platforms and allow the Windows instance to handle Windows file drops while the Linux instance handles Linux file drops. Obviously there is a cost penalty here as well as complexity during deployment.
Any thoughts or experiences are welcome.
Thank you.

Have you looked into relative path's? that would solve the issue of different OS path names.
Also, you might want to consider the deployment descriptors you can use when compiliing, you can set enviroment specific variables like paths in there.

Common video dimensions and bit rates for dynamic streaming?

I'm going to be converting my videos to flv and am trying to decide what to use for video dimensions and bit rates. Some of my users have slow computers and connections so I'm thinking 150 on the low end.
Is there a common practice? What has worked well for you in the past?

Hello MrWizzer
I am not sure what FMS version you are currently using.
Well, if you look at the sampe vod folder that ships with FMS4.5, it has files encoded @ 150kbps, 500 kbps, 700 kbps, 1000 kbps, 1500 kbps.
I am sure that all of these files stream perfectly fine given the correct bandwidth environment.
Its totally depend upon the FMS hosting service provider depending upon the user base of a particular provider.
You need to judge what kind of BW is available to your viewers and put the files encoded at appropriate bitrates.
You may also look at http://www.adobe.com/devnet/flashmediaserver/articles/beginning-fms45-pt06.html for refrences.

How to determine the bit rate with button over video subtitles?

I have a project where I've got several questions that come up on the screen. The DVD is subtitled in 14 languages, so depending on the language chosen, it will show the question in the proper language along with navigation buttons to go to the next question or track.
The problem is this: I added several new questions that each have a black only video that runs about 1min with 14 subtitle tracks made from photoshop psds. When I try to build, it fails saying "bit rate too high." When I removed all but 5 of the subtitle tracks, then it would build. I came up with a workaround, but then hit the limit of 99 tracks, menus or stories on a DVD.
I went back and tried combining all 3 questions in to one slide, but now with more information on the psd, it will only allow 3 subtitle tracks before it reaches the max bit rate.
How does it determine the bit rate? What can I do to lower the rate? I tried compressing the video at the lowest bitrate, but it didn't' help. I tried changing the psds to much smaller jpg files, but it didn't change anything. If anyone has any suggestions, please let me know!
Thanks.

CS,
Almost all DVD SP Tracks should first be completely constructed in a Sequence in FCP, the markers placed there, and then everything encoded into a single Mpeg 2 clip with matching length audio (even if just low bit rate AC3 silent audio, as the case may be, because all Mpeg 2 clips in the Title domain should be accompanied by an audio stream), and then imported into DVD SP.
Lay your subtitles under that and see what happens.
Take care,

Streaming multi bit rate and single bit rate

I'm trying to simplify my setup. Sometimes I need to stream multi bit rate and sometimes I need to stream single bit rate. This is due to the internet connections I'm sending from sometimes have poor upstream and multi-bit rate is too much bandwidth to send... So.... We resort to single bitrate. As I understand my encoder and server settings are different for each of these... I created a single and multi-bitrate profile for Adobe Media Encoder. That was simple enough. My question/concern is in regards the server settings. I would like to have a server setting for multi-bitrate and a setting for single bit rate. My goal is to void making changes on the server. I simply want to load the desired Adobe Media Encoder Profile. So, do I need to create a dedicated event for single bitrate? Below is the syntax I send to my server from Adobe Live Encoder. Instead of using 'liveevent' for my event would I just give it a different name? Does this stand true for my .m3u8 files? I'm confused to how to name differnet event/streams....
livestream%i?adbe-live-event=liveevent&adbe-record-mode=record

Hi,
When you use a setting like: livestream%i?adbe-live-event=liveevent then the encoder expects multibitrate streams (the %i is replaced by a number so the streams published will be livestream1, livestream2 and livestream3). You cannot use the same setting in the encoder for single stream. Instead you'll have to use livestream?adbe-live-event=<event_name>. You could create a new event under the same application.
Hope this helps. Let me know if you have any other queries.
Thanks,
Apurva

Bit rate standards for Compressing video for Captivate

I have been trying to decide whether rto use constant bit rate or a variable bit rate when compressing my video to embed in Captivate.
I have been told by Connect support that a constant bit rate is better for deploying video in Presenter but I am wondering if anyone has information as whether that is also true for Captivate. We are using captive as a means to offer a series of video question and answer sequence for a client of ours, and I am interested in getting the best quality with the smoothest performance in a progressive download flv format
For a simple talking head I am tempted to use a variable bit rate but, I cannot find anything in the seaces I have made that talk about the spec or any pros an cons to that quetsion for Captivate.
Doee anyone have any expereince with that?

I have always used constant bitrate for videos imported into Captivate and that has worked fine. However, I never tried using variable bit rate so I don't know if it will work better or worse.
My guess is that it would be better to go with constant bitrate though because Captivate do have some funny issues with FLV's sometimes and it's probably better not to "stress" captivate ;o)
