Why do YouTube videos lag when I switch to 720p?

Hi guys,
I'm extremely annoyed by the fact that everytime I watch a YouTube video and switch the quality from a standard 480p to a 720p or 1080p HD, the video gets lagged out. After restarting my Macbook Pro, it gets better and in a short while when I try to view it in 720p again, it gets laggy again. I have no problems viewing it in 320p or 480p. I notice this happens after I installed a number of updates on my Mac OS X 10.
Here's a list of updates I made.
(1) iTunes 10.4
(2) Mac OS X Update 10.6.8
(3) iMovie 9.0.4
(4) Remote Desktop Client Update 3.5.1
(5) Digital Camera Raw Compatibility Update 3.7
(6) Java for Mac OS X 10.6 Update 5 1.0
(7) AirPort Utility 5.5.3
(8) Migration Assistant Update for Mac OS X 1.0
(9) Safari 5.1
(10) iDVD 7.1.2
(11) ProApps QuickTime codecs 1.0
Does anybody have any idea which of these updates that has caused my Macbook Pro to react unusually? Everything seems pretty normal except this YouTube video.
Thanks.

A lot of people on the other forums seem to suggest it's the internet connection.
I can tell you for one that I have never experienced anything like this before. In the past two years with the same internet plan, I have been able to watch 720p and 1080p HD YouTube videos without any problem. Just today after installing those updates, the video gets lagged whenever I switched to 720p HD.
I just restarted my Macbook Pro and everything is fine for now. In half an hour or so, it's gonna happen again.

Why wont Youtube videos load when using Firefox 3.6.3?

I've been having issues with youtube when using firefox, the video doesnt load or show up for that matter its just a black screen where the video should be and on the bottom left hand corner of Mozzilla it says "done" I've tried everything, I updated java and flash but nothing seems to work. What can I do? I know I can use other web browsers but I really want to fix this
== URL of affected sites ==

There are a few reasons why youtube might be broken:
* An extension may be causing the problem: try the steps at [[Troubleshooting extensions and themes]]
* ''Bad item stored in the Browser Cache'': Follow the steps at [[How to clear the cache]].
* Firewall software is blocking some resources on the page: see [[Firewalls]]
If none of this works, let me know if Flash video from other sites work. Here are a few you can try:

Why do youtube videos blink when you scroll up and down the page?

<blockquote>Locking duplicate thread.<br>
Please continue here: [/questions/788365]</blockquote><br>
for some reason out of the blue youtube blinks when I am scrolling on a page while playing a video. I tried deleting the cookies which appears to have worked until I re-logged into my youtube account and any video I watch still blinks. Have any ideas?

Hello toekneesee, try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
[[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
[[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

Add to playlist to watch it later on a PC." At that point I was able to seach & select other videos by the artist (George Strait) off youtube and play them pkay on my Iphone, but not this particular one posted on facebook. Oh well.. I've spent enough time on this one, I know when I can't get there from here..

For some reason , when i restore my iphone 4s to factory settings my headphones work when listening to music or youtube videos but when i backup my information onto it , it only comes out of one ear bud and i just got a new one from the apple store.

for some reason , when i restore my iphone 4s to factory settings my headphones work when listening to music or youtube videos but when i backup my information onto it , it only comes out of one ear bud and i just got a new one from the apple store. my old iphone 4s audio jack was messed up but i just got a new one with my warranty , can anyone help me please.

It doesn't matter what it is in your backup that's causing the problem because you can not selectively restore things from your backup. It's all or nothing.
Set you phone up as a new device and start over.

Dealing With The Resume Feature of Lion
Managing Mac OS X Lion's application resume feature.
If you shutdown your computer you should get a dialog asking if you want applications to resume on the next startup. Simply uncheck the box to prevent that from occurring. Open General preferences and uncheck the option to Restore windows when quitting and re-opening apps. You can also install a third-party utility to control resume features on individual applications: RestoreMeNot or Application State Cleaner.
It is possible to completely stop the Resume feature although I'm unconvinced that it is that annoying. Nevertheless see the following:
If you have not yet done so you must first make your /Home/Library/ folder visible. Open the Terminal application in the Utilities folder. At the prompt paste the following command line:
chflags nohidden ~/Library
Press RETURN. Quit the Terminal application.
In the Finder navigate to the /Home/Library/Saved Application State/ folder. Delete the contents of the folder. Back up to the /Home/Library/ folder. Select the Saved Application State folder. Press COMMAND-I to open the Get Info window. In the Sharing and Permissions panel at the bottom click on the lock icon and authenticate. Set each of the listed entries to Read Only. Close the Get Info window.
Quit all open programs except the Finder (this is very important.) Next, navigate to the /Home/Library/Preferences/ByHost/ folder. Look for a .plist file with "com.apple.loginwindow." in the file name followed by some numbers in hexadecimal. Select the file. Press COMMAND-I to open the Get Info window and in the Sharing and Permissions panel click on the lock icon and authenticate. Set each of the listed entries to Read Only. Close the Get Info window. If you also find a file with the same filename but with a last extension of ".lockfile," then you should delete it.
The above should eliminate the Resume feature system-wide. Note that any future system updates or upgrades will likely undo these changes. You will then need to repeat this procedure assuming there are no major changes in OS X related to it.

Flash video lags when uploaded to Youtube.

Hi.
I have tried to upload one of my flash videos on youtube, the only problem is that it lags!
The sound is perfect, but the film only shows about 1 frame per second, when it's supposed to be 12 frames per second. This is obviously nothing worth watching when the picture lags as much as it does.
I have uploaded the same video on my facebook profile, and it worked pretty good, but as I already said, it lags when it is on youtube.
I don't have any movieclips in the movie I uploaded to Youtube.
Does it have anything to do with the settings on the movie? I eksported it in to a quiktime film before I uploaded it to youtube. I saw a tutorial where the person exported his flash into quiktime and uploaded it to youtube, and the animations were smooth, but when I do this, it lags.
Can anybody help me?

I don't see that. To me, it looks the same quality as any YouTube video.

RMBP, Chrome, Youtube: Video delays when in full screen

Hi all,
I have a retina Macbook Pro running Mac OS X 10.8.2, Chrome 25.0.1364.99. When I watch youtube videos there is normally no lag. Once I switch into full screen mode, there's a slight delay where instead of the video the screen will show a blank white screen before switching to the video.
This results in a slight 0.5-1s lag of the video behind the audio.
Opening the same video on Firefox and going to full screen doesn't result in this blank white screen and does not result in video lagging behind audio.
Any suggestions?
Thanks in advance.

Thank you,
it also worked for me

Why do YouTube videos sputter on iPad?

I have a 10mb cable company connection and an apple base station.
All is fine surfing, downloading etc. everything exc,eat trying to watch a YouTube video.
The video starts, stops, starts then stops for a few minutes then starts again. If I click pause I expect it to continue downloading so I can then watch but it does not do that.
Why is this happening with just YouTube?
Any advice?

Your wireless connection/speed is probably the limiting download speed factor>>
That's what I was thinking. When downloading I watch the status bar and it is usually about 140-180 "somethings" per sec. but sometimes it just dies at about 15-20.
Is your wireless "b", "g" or "n"?>>
I've no idea what that means or what I have : ( It is Sprint Broadband. As you know, many of the big companys are wired into the Windoze/MicroDevil stuff so I have no software available on the CD they supply. In fact no prefs are offered beyond Show time or status of hookup. I had to go to their website to download an installer .dmg!
If you make an ethernet cable connection (non-wireless), do you still get the sputter?>>
I'm on the road in a motor home so I've never done anything but Airport and Sprint. But it is the same with my iBook and my Pismo. Does processor speed play any role in the down loads? I have a 120 Gb 5400 Seagate Momentus to put in my Pismo. I was wondering if a side benefit would be faster web work?
Re replay - after you have watched a video once,>>
Duh! I kinda thought that's what you meant. Since I rarely see a vid all the way through, I've never tried it...well maybe the cat Nora playing the piano, but only that one : )
Shoul play at proper speed.>>
I'll try it out. It is just so frustrating to wait with all the stop/start stumbles.

Why do Youtube videos show being completely loaded, but aren't actually loaded?

It's kinda hard to explain. Ever since downloading Firefox 4, I've been getting this odd error in Youtube, and Youtube only. When viewing a video, the time bar or whatever you want to call it shows it's fully loaded, even when just starting to view. Also, when it ends the recommended videos, replay button, Like button, etc, show up a good 3-5 seconds before the video actually ends. This is not an error with Youtube itself. Since I tested it in other browsers. Namely Google Chrome, Opera and even Internet Explorer and didn't experience this problem. What should I do?

It's very difficult to say without knowing more about your system. There are a number of possibilities. First, your 13" lacks a discrete GPU, so the CPU is doing the work that a GPU would have done as far as decoding video streams, etc. Each video stream will consume considerable resources from the machine, and if you have multiple things running with video streams being decoded (for example, a browser with video Flash or cumbersome animation and iMovie running at the same time), then that may be a factor.
Additionally, it could be that you are memory constrained. You didn't post a picture of the process list from activity monitor or the memory usage stats, but you probably want to look and see what the memory and CPU usage is and who's consuming what. Some applications are pretty inefficient. For example, if you have iPhoto open and have thousands of images, the indexed metadata and thumbnails are all stored in RAM. iMovie pulls in clip thumbnail sets - (and worse, it has to do on-the-fly transcoding video assets from some cameras that don't encode the video using the parameters it expects to make indexing frames easier). Again, this would show up as periodic spikes in CPU activity for the app.
You seem to have plenty of disk space, that's not likely to be a problem.
Check if Time Machine is running. Time Machine introduces a performance impact, but it's exacerbated by the presence of frequently changed large files (e.g., you don't want Time Machine backing up your video projects while you are working on them).
Lastly, you may consider checking the console for error messages. This might reveal background processes that might be bogging down the system, or things like filesystem/disk errors. If there are errors in the filesystem, when you access certain portions of the disk, the OS and applications can slow down or lock-up as a result.

Video lags when I add effects

When ever I ad effects to my video the video lags. Its fine when I export it. Is there anyway I can turn the videoquality down to stop this or something,

Right now I am using the blink effect. I wasn’t sure if it was just that effect so I tried the emboss effect and a blur effect and the video seemed to lag when I used them as well. When I export the video the blink effect runs smoothly, but its hard to tell if I got the video how I want it when it lags in the preview window.

Youtube videos freezing when trying to watch, hibernate problem. Brand new Lion install

Hello,
I have just reinstalled Lion from the recovery partition, straight Lion install so no Snow Leopard to Lion upgrade.
I have carried out all software updates etc. However, when I attempt to watch videos on youtube the player freezes my page and it fails to load. I have also experienced problems going fullscreen. I use safari and not a third party browser.
I have a 2.4ghz Core i5, with 4gb ram and a 10mbps broadband connection, so can't really see this being a performance issue.
The laptop should still be under Applecare so if needs be it is an option, but if I can get this is something quick and easy to fix then that would be ideal.
Also it might be worth to note that sometimes the laptop has problems coming out of a sleeping state, the keyboard will light up and I can see a very dark picture on my screen if I concentrate, the only way I can recover from this is to hold the power button to turn it off.
Any help would be greatly appreciated, these problems have been driving me insane!

Most YouTube videos require the Flash plugin. Try troubleshooting ..
Quit Safari.
Open System Preferences > Flash Player then select the Storage tab. Click: Delete All
Now uninstall the Flash plugin then reinstall new > Troubleshoot Flash Player | Mac OS
Very important to uninstall the currently installed Flash plugin first before re installing.
Launch Safari From your Safari menu bar click Safari > Empty Cache
Now try a video.
BTW... if you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. It can also be installed as a plugin in /Library/Internet-Plug-Ins.
And check to see if Safari is running in 32 bit mode. Right or control click the Safari icon in your Applications folder then click Get Info. If the box next to: Open in 32 bit mode is selected, deselect, quit then relaunch Safari.
Also it might be worth to note that sometimes the laptop has problems coming out of a sleeping state, the keyboard will light up and I can see a very dark picture on my screen
Try resetting the Resetting the System Management Controller (SMC)
Doubtful the Flash issue is related to sleep mode.

Major Youtube Video Lag

I've been having a problem with youtube for a while, where the videos will play like a badly made stop motion film. The audio runs fine, but the videos cannot play normaly. Halp!

I just got off the phone with Apple regarding a similar issue with my MacBook Pro 15" that I just bought last August. My situation: when watching videos in HD on Youtube/Vimeo/etc., when playing, the video will pause, the load ring will start spinning in the middle of the screen for about 2 seconds, video will continue, only to restart the process all over again. This only did it in fullscreen HD (720 or greater), but worked fine in the default mini-screen on the page.
The only reason I bring all this up is hopefully you can use it to troubleshoot your system with the same methods and rule out possibilities. The tech asked me if I had Firefox and to check and see if I had the same problem in that browser. To my surprise, it worked just fine in Firefox, so that means that it is a Safari issue. In Safari, click on the "Safari" name in the header (up by the apple where you do your software updates and so forth) and choose "Reset Safari". From there, I simply selected "Empty the Cache", "Clear The Downloads Window", "Remove All Cookies", and "Remove All Website Icons". You can choose whichever ones you like. If you are experiencing the same problems in Firefox, click "Tools", "Clear Private Data...", and follow the same procedures.
Mine works just fine now! It makes sense as I didn't have this problem when I first got my computer. They recommend that you do this at least once a month as all of these temporary files and so forth can bog the system down. Anyway, I really hope that this helps.
In Him,
m.

Why is the video buffering when downloading

why is the video that I am downloading buffering on my imac.

Probably because your Internet connection is too slow. What speed is your connection? Your computer is running much faster than your connection can provide the movie data.
