Studdering... buffer slower than movie

I have employed two different methods to embed an flv movie in webpage, but both result in studdering because the movie catches up to the buffer.   I can't figure out what is wrong... is the frame of 30fps rate too high?  is my method of embedding the files and playback wrong?  Or is it just a function of the viewer's internet speed?    Is there a better technique?   Any feedback and help is greatly appreciated.
Method 1:
Dreamweaver > Insert Flash Video
FLV size:  13,428kb
Play time: 2:31
URL: 
http://waterstoneproductions.com/alternative-breaks-video.htm
Code:
Method 2:
Import video into Action Script 3.0 file (set frame rate of stage to 30fps) and publish swf
FLV size: 15,124kb
Play time: 2:31
URL:  http://waterstoneproductions.com/waters-color-video.htm
Code:

Thanks for that clue!
The bitrate of the flv file is 600 kbps.  Codec used is On2 VP6.
Assuming the connection speed is 625 kbps or greater,  I'm guessing I should only need 1 second of buffering.  Is that correct?
I can control the buffer setting in the action script/swf file, but how would I control it if I just use Dreamweaver to insert the flv?
And which method is the preferred method, given the size of my video?

  • Flash player 10.1 slower than 10

    At least, that's how it is on my secondary computers. On my Dell Inspiron B120, flash 10.1 latest is like a train wreck when it comes to playing Youtube videos in full screen. Disabling hardware acceleration helped a little, but this shouldn't be happening as I uninstalled 10.1 and installed an archived version of Flash 10 with much better playback AND with h/w acceleration enabled. The laptop uses XP SP3 and Firefox.
    Simply put, Flash 10.1 feels a lot slower than 10 on my Dell laptop (1.4 GHz celeron-M, intel 915g video, 512 mb ram)
    And there's another odd but minor problem I seem to be having with is flash animations on my main computer and any other computer/laptop I have using Flash 10.1. I get this alternating 'lag' every few seconds; it's like the computer is dropping frames because the CPU can't keep up. I could completely understand this, but this is happening on practically any flash animation I throw at the computer. I just tested a flash movie (SWF format) on my main computer (2.8 GHz AMD Athlon x2 240; 2 gb ram, Windows 7 x64, Firefox) and I get this irritating choppy lag here and there. Again, with the previous Flash version 10, I did NOT have this problem AT ALL. Everything was silky smooth; the only benefit I'm getting from Flash 10.1 is x264 hardware acceleration for my ATI Radeon 4200 HD. Before anyone asks, all of my computers were using the latest flash version AND video drivers prior to these tests.
    I am VERY frustrated with these problems as I've posted a similar thread twice now in the past. No one seems to be answering or helping me with this; Those that do reply simply claim that they're having the same problem.
    Adobe, please look into this problem. Eventually Youtube and several other sites will force me to upgrade my laptop to Flash 10.1.

    Has Adobe fixed the problems with version 10,1,82,76 of flash player ?
    I compared it and found nothing but problems.
    I then uninstalled 10,1,82,76 and rolled back to 10,0,12,36 which works fine on Firefox and Opera but I can't install 10,0,12,36 on Exploer or Chrome
    it keeps telling me there is a new version even when I try to install it from local drive with a archived version.
    With all the complaints about 10,1,82,76 and the lack of response from Adobe on any fixes I will not be using Adobe auto updates until I let some
    other poor guinea pigs suffer all the bugs and problems first.
    You would expect a large company to have better development and testing before imposing buggy upgardes on us.

  • How can I revert back to 10.0.2. 10.0.3 is slower than Final Cut Pro 3 on my Power PC.

    How can I revert back to 10.0.2. 10.0.3 is slower than Final Cut Pro 3 on my Power PC.

    I was able to switch out my HD to a previous drive with Snow Leopoard and FCPX 10.0.2. Final Cut Pro is working again like magic! I don't think it has anything to do with Lion. I already miss some of it's features. I am once again scrolling backwards. Within 5 minutes of using FCP 10.0.2 I already notice huge improvements of speed and lack of beach ball. I can honestly say that 10.0.3 is a completely unsuable application unless you have the patience to wait 15-30 seconds between the pushing of any button on the keyboard or the slightest movement of the mouse, well trackpad. Either way FCPX 10.0.3 is a dissappointment on so many levels. I am even giving up my solid state drive to revert back to the awesomeness of FCP 10.0.2.
    Really looking forward to the improvements on FCPX but feel that Apple should be releasing the software as Beta and offering it free for those who want to help develop and make it better.

  • On Mac FAT32 Format Slower Than HFS

    My 60GB iPod came in Windows FAT32 format which I liked since I could use it in disk mode on both Mac & Windows. However it seemed slow to start playing video and when switching between video files.
    I did some timing tests and on the Mac FAT32 was much slower than HFS.
    FAT32
    Start playing movie = 12s
    Stop movie and restart at same location = between 12-30s
    HFS
    Start playing movie = 5s
    Stop movie and restart at same location = between 6s
    If you have a Mac and your new 5G iPod is formatted for Windows, you may want to use the iPod Updated to restore and make the drive HFS.

    > Any NI techs have any insight as to why? Is there some Endian
    > conversion being done internally? Any workarounds?
    Well, there isn't any endian conversions going on. Both the file and
    Mac memory model are big-endian. But the classic Mac file I/O is pretty
    slow. The only thing I can recommend is to do the reads in larger
    blocks. I've also heard some people claim that running their file I/O
    bound apps underneath OSX will speed things up. In other words, running
    an OS9 app underneath OSX is actually more efficient because it replaces
    all of the OS9 code. So, you could give that a shot.

  • Safari MUCH slower than Explorer on same computer. Why?

    I have Comcast cable internet and I've noticed that my Safari (1.3.2) has been getting increasingly slow, very slow over the past several weeks. So I've been using Explorer (5.2.3) which is blazing fast comparatively. Why is this and is there anything I can do to Safari to get the same performance I'm getting from IE?
    Safari has all my bookmarks. I've done the import bookmarks thing into IE but it just creates a "Bookmarks.plist" which, as far as I can tell, does nothing. Also my email application automatically launches Safari for links in email and I can't figure out how to get it to launch IE instead.
    So if I can get these latter two issues resolved I'm fine using IE. So I'll take advice on that as well.
    iMac   Mac OS X (10.3.9)   Safari 1.3.2

    Internet Explorer has not been supported by Microsoft for some time. It is not as secure as current browsers. Firefox, Camino, Mozilla, Opera would be viable free alternatives to Safari.
    Safari
    If you are experiencing slower than usual operation, there are some steps you can take to perhaps improve the speed:
    General - System Maintenance is important. Have a look at this MacWorld article for guidance.
    Safari - Safari menu>Empty Cache is a good start.
    Unplug your cable box, wait 30 seconds, plug-in to reset your ISP's address.
    Go to your Network>TCP panel. Select "configure IPv6". Set to "off". Select "apply".
    Go to your User Library>Safari folder. Move the Icon folder to the trash. This folder holds the small image files appearing next to the web address in the address bar. This file can become corrupt slowing things down. When you move it to the trash, Safari creates a new folder on the restart. Over time, the icon file rebuilds itself based on sites you access.
    You can also move the Safari preference file .com.apple.safari.plist to the trash. When you restart Safari you'll need to reset your custom preferences, so mark them down for reference before moving the file. This file is accessed by a number of applications including Mail. Each time the file is accessed it is susceptible to corruption. Trashing the old gives you a fresh version. The file can be found at User>Library>Preferences
    Restart Safari after completing the above.
    There are other steps, however, I think this is a good start. Post back with results.

  • After Effects Render SLOW - Slower than my old PC

    I am using a new 1 month old 20" iMac, 2.0Ghz with 4gb DDR2 RAM, running OS X Leopard. Adobe After Effects CS3 is rendering really slow, and I mean like the same as my PC. Also the same with Premiere Pro, it renders really slow and I have tried different formats too, in premiere pro it took 2 hours to render a 5 minute video (saved to .mp4 640x480 pixels, end size was 20mb). This is wayyy to slow.
    I compared my Mac with my old PC running Windows XP, it is pentium 4, 3.2Ghz with Hyper threading technonlogy and 1.5 GB DDR Ram. I tested rendering andrew kramers 3d room tutorial, I downloaded the project file. I only chose to render some of it and the old PC was FASTER than the Mac by around 15-20%. BUT, the mac was ONLY using 6% of the 3gb (it only recognises 3 gig not 4 but I dont mind that too much) and the PC was using 60-70% of the 1.5GB (thats using more RAM than the mac) So why can't I get the Mac to use more RAM when rendering, and why is it slower??? It is faster at EVERYTHING else, well the ram preview is about the same.
    How can I get my mac to use more of the RAM and why is it rendering and previewing the same if not SLOWER than my 5 year old PC?
    Any help would be awesome, thanks

    RAM allocation is dynamic, you cannot enforce anything on that end. AE takes what it needs and no more. I would think that your issue has to do with the graphics card/ chipset, so my first suggestion would be to make sure you have updated your AE to the 8.0.2 patch. Secondly, run a software update for your Mac. If neither of this applies and brings any betterment, disable the AE_OpenGL.plugin. Simply delete it or move it outside the AE directory. Most certainly your issues hinge on your graphics hardware, so one of the previous recommendations should yield a noticable effect.

  • Premiere CS6 slower than 5.5

    We have recently migrate from CS 5.5 to CS6. We install Production premium in many PCs. (same hardware we used for 5.5.) and our editors realized that CS6 moves slower than 5.5.
    They used to work very fast and sometimes they have to wait to CS6 to react. Sometimes is no more than 4 or 5 seconds but this is very annoying for someone who needs to keep fast rhythm to finish on time.
    We have already:
    - update drivers for gpu
    - updated premiere to 6.05
    Systems:
    PCs:
    - i7
    -24GB RAM
    -GPU Nvidia GTX 570
    -SSD Operating System
    -RAID o for video + 2 more HD(1 tera each), for media cache and previews
    This issue happends in all our machines.
    We work with same kind of footage (mpeg 2) and same hardware and this issue,never happened in CS5.5.
    Is there a way to fix it?              
    Thank you

    I know this is always an option, but the idea is to find out if there is a solution for this in CS6, so we can take advantage of the improvements of this version. (CC is not an option for us right now)

  • PXI: NI 5600, data lost or stored if the loop time of processing is slow than the acquisition.

    I want to know what occurs exactly at the time of L acquisition and the processing data acquired with Ni 5600.  When J write my programme of processing of data in Labview, if the loop time of processing of data is slow than the acquisition, I want to know if PXI put the data in a buffer or then the data are lost. 
    J wait your answer impatiently. You can tell me the documentation were can i read to see the answer.
    Anybody can help me.

    hi abidi,
    First, let me tell you how buffered acquisiton works.
    If you are using Daq mx for continous acquisition, Labview will autoselect the size of buffer depending on the sampling rate specified.
    In sample clock.vi, select sample mode as "continous samples".
    Now, Labview will determine the loop speed for reading data that is written into the AI buffer and hence run  necssary number of AI read loops to retrieve data from the buffer every second.
    this loop speed can also be set by specifying "number of samples per channel" in AI read.vi.
    If you leave this value at default ( -1) labview will function as explained above
    This can also be set by user ,for example, if your sampling rate is 1000 saples per sec and number of samples per channel is 200, the AI Read functions is performed 5 times in a second. 
    read this link to get to know about cyclic buffers and continous acquisition.
    http://zone.ni.com/devzone/conceptd.nsf/webmain/F2DDCBAD754C687C86256802007B8514
    You tell that you are performing some processing on acquired data.
    Now, your prgram has to allocate adequate process time for acquiring,retriving data from buffer and then processing it.
    the time allocated for processing data depends on the kind of mathematical conversions involved. Nevertheless it is an overhead on the acquisition loop.
    this may result in overflow of buffer and data being overwrittien in buffer which results in data loss. An eror message might also pop up to warn that this has happened.
    so if your application permits, here's what you can do to avoid this problem
    First acquire data and save it on system in ascii or binary fromat.
    later retrieve this data file and perform processing /analysis on it.
    if you have any further doubts, plz tell.
    regards,

  • My four year old iMac is running much slower than when it was new.  Any suggestions on cleaning out the cob webs?

    My four year old iMac is running much slower than when it was new.  Does anyone have any suggestions on what I can do to "clean it up" and get it running like it used to?

    What year, screen size, CPU speed and amount of RAM installed?
    To find out info about your system,
    Click on the Apple symbol in the upper left of the OS X main menu bar. A drop down menu appears.
    Click About this Mac. A smaller popup window appears. This gives you basic info like what version of OS X your iMac is running, the speed of your iMac's CPU and how much RAM is installed.
    Click on the button that says More Info. A larger window appears giving you a complete overview of your iMac's hardware specs.
    Highlight all of this info and copy/paste all of this into another reply to this post, editing out your iMac's serial number before actually posting the reply.
    This will tell us everything about your iMac so we may begin to help with your iMac issues.
    How full is your Mac's hard drive?
    Locate your iMac's hard drive icon on the OS X desktop. Click the icon once, then use the keyboard key combination Command-I. This will give you additonal info about your iMac's internal hard drive.  
    Post this info in your reply here, also.
    Here are some general tips to keep your Mac's hard drive trim and slim as possible
    You should never, EVER let a conputer hard drive get completely full, EVER!
    With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
    If it does, it's time for some hard drive housecleaning.
    Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
    Have you emptied your Mac's Trash icon in the Dock?
    If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
    If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
    If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
    Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
    Look through your other Mailboxes and other Mail categories to see If there is other mail you can archive and/or delete.
    STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
    Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
    Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
    Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
    To find other large files, download an app called Omni Disk Sweeper.
    Download an app called OnyX for your version of OS X.
    When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
    Typically, iTunes and iPhoto libraries are the biggest users of HD space.
    move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
    If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
    Good Luck!

  • My iPhone 5 is slower than my iPhone 4s.

    My iPhone 5 is slower than my iPhone 4s. I have been using the iPhone 5 for about four days.
    1. I live in a very populated area of Texas, and I know 4G is available in my area, but I always am connected to 3g.
    2. Everything moves slower on the 5 than the 4s.
       A. Siri speaks in a lower pitched voice. She talks slower. She is more robotic sounding than the 4s.
        B. Siri takes a long time to respond. When I command "Text  George", Siri will spin and clock for 40 seconds to a minute befiore she responds with " Okay, I can text George" . When I speak a text it takes a long time to send.
        C. I have a new 2013 Ford that has Microsoft SYnc. My 4s found the bluetooth device immediately, i put in the pin and it sycned great and worked great. When I attempted to sync my new 5, it took a long time for the 5 to conect with my car. After entering the Sync pin, it took a long time to connect.
    I called Verizon and the customer service rep states he had a call with the same problem earlier today.
    I did erase all settings and re-activated the phone, but it is still slow.
    Furthermore, I gave my old 4s to my son, and I still can use it.  I can have the two phones next to each other and the 4s works fine...the 5 is slow, especially with Siri use.
    I will try to follow up with more info at a later date as I experience more problems

    Did you set up your iPhone 5 as new or restore from a backup of your iPhone 4S? 
    Set it up as new and see if it improves.

  • MBP slower than ever...

    I just upgraded to Snow Leopard, then swapped a 250gb 7200rpm hard drive for a 500gb 5400rpm hard drive. Now my computer is slower than ever. It still works, but at a much slower pace. Often the screen will freeze for up to 10 seconds before becoming operable again. This happens when doing the simplest of tasks. I am only running about 5 programs at a time anyways. This never happened on the old system. And I don't think its a matter of the slower hard drive. I was running an old MB with a smaller HD, same RPM, same RAM, and there was no problem. What gives? What should I do?

    OK. Let's proceed on the premise it's not the drive. Although, I swapped an 80GB 5400 drive on an iMac G4 for a 160 GB@7200 and noticed quite a difference.
    How did you install, clean install with Migration Assistant, clone, Time Machine?
    There are some simple troubleshooting steps you can take.
    Create a new User go to System Preferences >> Accounts >> "+" (make it an admin acct) and test your apps in this new account, if they are faster the problem is isolated to your User and not systemwide.
    If the issue is limited to your user account try starting up Safe Mode (It will take more time to startup in Safe Mode because it runs a directory check.)
    If your apps functions faster that way, go to System Preferences >> Accounts >> Login Items, and remove them. Boot normally and test. If not go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving ~(yourHome)/Library/Fonts to your desktop and restarting. Also, delete Users/yourname/Library/Caches. (on the first launch after this some apps will be slow until cache catches up.)
    Log out/in or restart, if that sorts it start putting items back one at a time until you find the culprit.
    If the issue is systemwide then, you may be able to repair this with the The 10.6.2 Combo Update This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before.
    Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
    Let us know.

  • Is Safari really slower than Firefox?!

    Hello,
    I'm trying to migrate to Safari, after years of using Firefox. One unsettling thing I've discovered is that for some reason when I click a bookmark in Safari very often there is a pregnant pause before it takes my to the requested page. Sometimes it freezes up all together & never takes me to the page so I have to retry getting to the page. This never happended with Firefox.
    Are my Safari settings somehow off or is Safari really that much slower than Firefox?
    Thanks.
    Jim

    Something's not right. Safari and Firefox should load pages the same.
    From your Safari menu bar click Safari > Reset Safari
    Select:  Clear History / Remove all website data / Clear the Downloads list
    Click Reset. Quit and relaunch Safari to test.
    If that didn't help, open a Finder window. From the Finder menu bar click Go > Go to Folder
    Type or copy paste the following:
    ~/Library/Caches/com.apple.Safari/Cache.db
    Click Go then move the Cache.db file to the Trash.
    Quit and relaunch Safari to test.
    If that didn't help, try troubleshooting extensions and third party plug-ins.
    From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test. If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.
    If it's not an extensions issue, try troubleshooting third party plug-ins.
    Back to Safari > Preferences. This time select the Security tab. Deselect:  Allow all other plug-ins. Quit and relaunch Safari to test.
    If that made a difference, instructions for troubleshooting plugins here.

  • Why is Airport Exp. with TimeCapsule slower than with just the TimeCapsule?

    I have a 500MB TimeCapsule (with a Comcast modem and 16mbps download). Within the room that the TimeCapsule is in, the signal is great. I decided to extend the signal down the hall with a (slightly older) Airport Express. Now that the signal has been extended, it is much slower than with just the TimeCapsule. I believe I'm getting something close to 65kbps with the Aiport Express extension, whereas I was getting well over a 3 mbps with just the TimeCapsule.
    Thanks for your help!

    +My question/input would be, the TC is 802.11n where the older a1084 AX is 802.11b/g, so wouldn't that also show a decrease in speed?+
    Yes, in a way. But, the speed on your local network will be much faster than your internet connection speed.
    a "g" network can handle 54Mbps, so worst case with the WDS, your local network speed would be 27Mbps. Your internet connection speed should stay about the same.
    If you decide to upgrade to an AirPort Express "n", you can configure your network to use Apple's "extend a wireless network feature". Results will be much faster "n" speeds and much less bandwidth loss.
    The faster speeds really only benefit you if you are moving large files or backing up on your local area network. Your Time Capsule backups would be much faster if you are using wireless if you move to the "extend" feature.

  • Preview takes forever to open, much slower than on my old MacBook. It has been like this since I bought the computer last January. Why is Lion so much slower?

    Take it to an Apple Store for testing. If you don't get immediate satisfaction, exchange it for another one, which you can do at no cost, no questions asked, within 14 days of delivery.
