Detecting Fast start or Hinted Streaming
I have got a task of making H264 files the same way they were made before I took over the job,... however in the Movie information tabs I do not see the the specification of whether it is "hinted streaming" or "fast start" or "fast start compressed". Is there any way of finding out from the old file? I know the videos are suppose to be streaming but I believe that they were only "fast start".
thanks for any information!
No way to tell about fast start except by testing the file from a server as it is a property of the individual file (part of the header info).
You could view this by using a "hex" editor but that would be a pain.
Streaming tracks are extra data and will show in the Movie Properties window. But these tracks are just extra file size and are ignored if your files merely download (not served via streaming server software like RTSP).
So. If your files are viewed in a Web page they only need fast start (Progressive Download). This is done at export (Movie to QuickTime Movie). As long as the file isn't edited after export fast start will remain. If edited and "saved" fast start is removed from the file. To restore fast start simple "Save As".
If you have a bunch of files that need to be fast start you can batch process using AppleScript or Automator.
Save as doesn't do any conversion so it is very fast. It does put your files tracks into a .mov container, however.

Detecting Fast Start QuickTime Movies
Is there a tool, programming approach, or way to applescript the detection of whether a movie was saved with fast start or not?
And if so, is there a programming approach or way to applescript QuickTime to quickly set, or resave the file without needing to reencode the file?
I need to create a process where I can verify that files on my server are set to fast start and if not then set them. Please help.
Thanks in advance

Anything supposedly saved by QT in the "MOV" container automatically defaults to "Fast Start." If in doubt or using other QT containers, simply use the "Save As ..." file option to resave these files with "Fast Start" without re-encoding. -
Hinted streaming, fast start and the results.
Hi,
I put some clips onto a website recently, some were 5 min movies. I was pleased with the results, as the movies started almost immediately on several computers I tried.
Unfortunately, the client had to wait over 4 min to see the video. My video was compressed with hinted streaming.
So of course 4 min. seems like they downloaded the whole video before it started.
I have a web guy looking into if perhaps this could be a server issue with the customer, but I wanted to check if anyone has some insight to this.
I personally am not really clear on the "hinted vs faststart"
Thanks
JeffHinted steaming is for streaming videos like the Apple's VideoKeynote presentations. For Example:
http://www.apple.com/quicktime/guide/appleevents/
Fast start is for progressive download of the video. For example:
http://www.apple.com/getamac/ads/
I have feeling your server is not a streaming server so you need fast start/progressive videos. A fast start video will begin to play after a few seconds while the video is being downloaded into the browser.
Open all your videos in Quicktime. Do a SAVE AS and save each video to a new folder. Doing this will activate (place back) the fast start in each video.
Send one video to the server for a test. Make sure your html embed code for the video has AutoPlay set to true.
(Steaming servers aren't cheap. If you click on the keynote presentation you'll notice that you can jump to anywhere in the video without having to wait for the video to load. Streaming videos don't download to you browser/computer, they stay on the server. Fast start/Progressive video download to you bowser/computer. Also streaming videos are one way to discourage people from downloading the videos. The only way to capture a streaming video is to use a screen capture program, Quicktime X has this capability.) -
Hinted streaming, fast start and fast start compressed header
Hi,
I am trying to export a movie trailer from FCP through Compressor for use on a website hosted by Wordpress. I am using h.264 and am trying to decide whether it is optimal to use hinted streaming, fast start or fast start compressed header. I found this discussion stream:
http://discussions.apple.com/thread.jspa?messageID=10451326
which was helpful, but stated explicitly to not use fast start compressed header. Can someone explain why not? I am also interested in a more in depth explanation of how/when you would choose each of these options.
Any insight would be greatly appreciated.
Thanks,
BeckyThe header information would normally be at the end of the file. Fast Start places it at the beginning so that this is the first part of the file to be loaded. This means that you can start playing the movie before it has finished downloading.
Fast Start Compressed Header goes one step further by compressing the header, but it is not always compatible with applications and I believe Adobe Flash Player is unable to play it.
Hinting tells the server the optimal method of streaming the movie, but this is only relevant if you have a streaming server (expensive). For most people, Fast Start will suffice. -
What format in expert settings for fast start on the web?
I exported a slide show to QT from iPhoto. Unlike imovie that gives you the possibility to use expert settings to export a fast start, iPhoto doe not have the option to export to expert settings.
I want my QT slide show to begin to play as it uploads on the .mac web page. By accident, (I don't know what I did) one of my video has a fast start on my web pages, it starts playing before it has finished uploading. On the other hand, most of my other videos or QT slide show, have to fully upload, which can take 5-10 minutes, before the viewer can see it playing.
Also, If I open my QT slide show exported from iPhoto in the size of 7.1MB, and re-export it using QT pro expert settings using Fast start, the file become 91MB big...... way too big to post on the .mac account!
What is the difference between hinted, streaming, fast start, and compressed header? I'm getting a little confused with the choices!!!
please help!
Any suggestions would be appreciated!!!
michelSome iPhoto slide shows (those that use only the fade effect) do not fast start. They are made up of three video tracks slightly offset in time and a tween track that sets the fade.
You could open them in QT Pro and use the save as menu. No re-compression but the file size will become three times larger because each of the video tracks will become independent (for lack of a better word). This new file will fast start.
Exporting isn't a good choice unless you use identical settings to the original (Photo-JPEG video codec and an extremely low frame rate).
The file size of the original is "trick" that can only be performed by iPhoto. -
ORA-16820: fast-start failover observer is no longer observing this databa
Wem have primary and physical standby of Oracle 11.2 on linux 2.6.18-92.el5. For a reason of hardware resources, we want to run the Observer on the standby machine. Here I have several questions:
1) Is it supported to run Observer on the standby?
2) Does fast-start failover means automatical detecting down of primary and switch over the role automatically? WE do not want automatical switch over.
3) Started Observer on the standby and run show configuration, get errorDGMGRL> show configuration;

Thanks.Answering all your questions
Does fast-start failover means automatical detecting down of primary and switch over the role automatically? WE do not want automatical switch over.
Fast-Start Failover is an Oracle Data Guard 10g Release 2 feature that automatically, quickly, and reliably fails over to a designated, synchronized standby database in the event of loss of the production database, without requiring manual intervention to execute the failover.
In addition, following a fast-start failover, the original production database is automatically reconfigured as a new standby database upon reconnection to the configuration. This enables Data Guard to restore disaster protection in the configuration quickly and easily, returning the database to a protected state as soon as possible.
Is it supported to run Observer on the standby?
There are three essential participants in a Fast-Start Failover configuration:
• The production database
• A target standby database
• The Fast-Start Failover Observer
The target standby database will become the new production database following a fast-start failover (note: There can be multiple standby databases in a Data Guard configuration, but only one can be designated as the fast-start failover target. A manual failover would be required in order to execute a failover to any of the additional standby databases within the configuration).
The Observer is a separate process incorporated into the DGMGRL client that continuously monitors the production database and the target standby database for possible failure conditions.
The rule is that out of these three participants, (production database, standby database & observer) whichever two can communicate with each other will determine the outcome of fast-start failover
Hope the above explaination answers your question. -
Fast start for Quicktime movies on the web
Hi All,
So I finished my first FCE project and posted the movie on my web site. But Quicktime doesn't start playing the movie until after it is completely downloaded. This doesn't happen with the other movies I have on my site, and as far as I can remember I used the sames options in Quicktime export. I selected the "fast start" option in the box "Prepare for Internet Streaming", as I always do.
Is there something more that I need to do when exporting a FCE project? Or is there another option that I forgot in the Quicktime export settings?
Thanks in advance for your help
FlorenceOK, I tried again and again and again... and I finally know what I did wrong. The movie was exported from FCE with the fast start option, but then I opened in with Quicktime to make a small change (define the poster), and apparently this also removed the fast start option. Now I'll know not to change anything after the export :-/

"fast start" for .MP4 H264/AAC ?
Hi,
I am looking now for a "fast start" option in Compressor 4 for .MP4 H264/AAC encoded files.
Is there a way to do that ?
Thanks
EricEric,
See if this works for you. Start with the Broadband High preset (you could use any preset). Open the Encoder pane; in File Format, choose Quick Time; Click on Video Settings and in Compression Settings, select H.264. Set your data and then Optimize for streaming. Return to Encoder and open Audio settings to specify thge format you want; In the Encoder, select Streaming and then select Fast Start. In the Extension box, change the extension from .mov to .mp4. You should wind up with a MP4 H.264 CBR preset.
Good luck.

How to export as mp4 and achieve effect of "fast start" in mov export
When exporting as a .mov one can check the "fast start" prepare for internet streaming option. This option allows the end user to start watching your video without waiting for the entire file to buffer/download. That's great.
However, when export as a .mp4 file, the same option does not exist.
Does anyone know how to achieve this "fast start" effect if exporting as an mp4?
I have an existing work around...just rename the .mov to .mp4.
I would like an .mp4 file because I use ezs3 to host my videos and the mp4 player options are far superior to the mov player options.
Thanks for your help.I'm having the same problem. I want to export an .mp4 that can start playing as soon as it starts downloading from a web site. Until I can find a solution, I'm using .m4v files, but they're huge.
Does anyone have a solution? -
QuickTime Fast Start Progressive Download not Working - Help!
I can't figure this out - I have a large number of training movies created by a contractor. After uploading them to my website, I thought QT would start once a certain amount of data was downloaded. So, being new to QT, I thought that the videos should be exported with the "Prepare for Internet Streaming." checked with either "Fast Start" or "Fast Start & Compressed Header" selected. Well, I tried both and no luck. File sizes are between 8 MB and 40 MB. I discovered another site that has a 80 MB file that starts no problem, so obviously I am missing something! Any suggestions?
Thanks,
SimonThanks for your purchase, Simon.
You should look at the part of my PDF that discusses QuickTime Media Links. These are text based files that will download with a click on the link and then can control the QuickTime Player application.
Your Web page layout could remain the same with these .qtl links and your QuickTime files could enter "Presentation" mode (full screen, if you like). They will launch the QuickTime Player app as the tiny .qtl file has downloaded or the .qtl download is double clicked. -
Carefully followed instructions for "Preparing a Movie for Fast Start". Uploaded the 5Mb file to my Web server and mailed the link to a friend. Friend says it took two minutes to start? I thought this was supposed to "stream". Any thought on where to look for cause and solution?
I thought this was supposed to "stream".
No, it is the playback of media which begins as soon as the player estimates it has cached sufficient data to preclude the premature stopping of playback before reaching the end of the file. If the internet connection data throughput is consistent, the estimate is usually fairly accurate. However, if it varies drastically, playback may be interrupted frequently during playback.
Any thought on where to look for cause and solution?
Check the internet connection speed, ensure "Fast Start" option is embedded, and/or ensure you are using a multimedia compression format/player setting that does not force playback to delay until the end of the file is downloaded.
Friend says it took two minutes to start?
2 minutes for a 5 MB file does sound a bit excessive. I have a test 20 MB file that takes less than 2 seconds (emptied cache) to begin playback using my ISP. Here is the QTL file link if you want to test it for comparison: TEST FILE -
Fast Start Failover has broken my Logical Standby and Flashback has not helped
I have a primary ( PRIMARYP ), a physical standby ( STANDBYP ) and a logical standby ( STANDBYL ).
I configured Fast Start Failover ( with STANDBYP as the target ) and started an Observer. I did a shutdown abort on my primary and the Fast Start Failover did make STANDBYP the primary. I was able to reinstate PRIMARYP as a physical standby.
However when I checked my broker config it gave for STANDBYL
ORA-16795: the standby database needs to be recreated
Strange I though, since I would have expected STANDBYL to survive ok given that the new primary, STANDBYP was a physical standby of PRIMARYP.
Not to worry I thought, I simply will flashback STANDBYL to the beginning of the day and SQL APPLY will reapply all the redo.
This is where the problem begins

Protection Modes and Fast-Start Failover
Oracle Maximum Availability Architecture allows you to set fast-start failover (FSF)to automatically failover to the standby in the event of losing the primary database.
One condition of FSF is that it will only initiate if there is a guarantee of no data loss. This is where i start getting confused. Maximum Availability mode allows for data loss as the primary will still process transactions if the connection to the standby is lost. This means then in the event of the standby being out of sync with the primary database (i.e. network glitches) and then losing the primary database to hardware issues for example. FSF will not be able to initiate as data will be lossed and a complete loss of service will happen!
Can FSF be used in Maximum Protection mode as this will always mean FSF will be able to occur? Also what is the overhead towards the databases with regards to running them in this mode?
Thanks,
ChrisHi,
Can FSF be used in Maximum Protection mode as this will always mean FSF will be able to occur? Yes, Maximum Protection Mode can be used with Fast-Start Failover, please review the next link.

ThanksHi DigerDBA
I did your advice , the error disappear, and thanks for your advice , but do I need to keep standby_file_management='AUTO' or 'MANUAL' in primary and standby init files?
Am asking this because when I use the observer the failover failed and I get the following error

ORA-00604: error occurred at recursive SQL level 1
