Choppy Video Performance

Safari is working for YouTube, but on other websites that have video content it gets choppy and very slow.
I tested my down load connection. It averages 2.3 Mbps. I'm using a 1 GHz G4 Powerbook with 768 MB Ram.
Firefox does the same thing as Safari.
Is there a better way to watch these video websites?
Jesse Tyler

Recent updates or changes I did not deliberately make to my old G4 have made Safari performance sluggish in all aspects. Safari 3.1.1, MacOS 10.4.11.
Scrolling with the mighty mouse hesitates.
All video clips, including native QT, stutters.
Even typing is sluggish, characters appears one or two keystrokes behind the keyboard activity. I cannot accurately select text in a field. Backspacing to delete text entry on a Web field takes several heartbeats for the cursor to move. It's weird.
Searching through the forum has led me to try several suggested cures but, since these issues are present only in Safari, my intuition tells me this is a problem with the application, not with Safari's caches or permissions or .plists. Deleting or purging those items did nothing to improve the performance.

Choppy video performance with Intel X4500HD

Hey I am getting choppy video play back with my Intel X4500HD. I can watch small youtube videos fine, but if I fullscreen a movies I get pretty bad preformace. The X4500HD is supposed to be able to play HD Movies so I know my system is quite capable.

The only thing that I can think of is that my video chipset is kind of new, and that it has poor support with my current video drivers.

Choppy video playback with airplay from Macbook Pro

I experience very choppy video using airplay towards my Airplay unit (3rd gen).
I am using a Macbook Pro (15" retina, late 2013 version) with these specifications:
- Intel Core i7 2.7 GHz.
- 16 GB ram.
- 768 GB flash/SSD.
...and so on. I have the Mavericks OS installed (10.9.1).
When I duplicate or extend the screen of the computer to my Apple TV it is chopping EXTREMELY much. I am not talking a little bit - but it is not even watchable. I thought that it could be the router itself as the connection is (probably, correct me if I am wrong anyone) is directed from the computer - to the router - and then to the Apple TV, which could make the router like a filter in the process. And if something would prevent the signal from reaching the Apple TV with "full speed" it could prevent the actuall image.
However, when I am using the iPhone 4S and streaming video (both video found in my phone as well as streamed TV from apps such as Magine.com) the image flows completely flawless. There are not even a touch of lagging. It flows perfect, just as watching a movie directly on the TV.
The networking hardware in the phone is slower than in the Macbook Pro retina (late 2013) - both for sending and recieving data. But still... my iPhone works better than the Macbook Pro for the Apple TV. Even though that the processing, memory, graphic and networking power is probably a thousand times faster in the computer... it still performs really bad.
I have followed some discussion threads here (https://discussions.apple.com/message/22051725#22051725 and https://discussions.apple.com/thread/5734226?tstart=0 just as a couple of examples). I have accessed my router (Netgear Gigabit EVG 2000) and increased the Wireless mode to "up to 270 Mbps. I have also followed the previously linked threads and disabled the WMM (in the QoS-section). I felt that this made a little bit of a difference...
...when I am mirroring the screen and scale down the resolution to match the AirPlay screen (full-HD, 1920 x 1080) it works okay, but still chops quite a bit almost all the time. But if I extend the screen and want to watch TV at the same time as I am doing something else on the computer - then it chops so that it is not even possible to watch.
This have to be something either with the Mavericks OS or with my network settings - can anyone help me...? It would mean A LOT!

Curious why you think it would be my network when the same network is being used by the iPad 3rd Gen and iPhone 5 and they both stream without issue. As far as the other items you mentioned, all devices are up-to-date with the latest firmware/software and the latest MacBooks do not have ethernet ports. Speedtests that I have conducted also indicate that bandwidth is not the issue as the results show that the speeds received from the router are quite impressive.

Unreliable Video performance in Premiere Pro CS5.5

Hi there all ..Since rebuilding my PC to replace the original rotating OS disk with an SSD, I have been having all sorts of hassle with Premiere Pro CS5.5... in essence, video is often (but always) choppy although the frame counter advances smoothly... Audio is OK
The issue that causes me the most angst is the demand for hi speed transfer... Why is this needed? Here is the root of my lack of understanding:
I can record 113 minutes of 1920 x 1080 imagery at 25fps on a single 32GB Secure Digital card.. this represents a transfer rate of less than less than 5MB per sec.. So why can't my external G-Speed 4-drive bay (using a pair of drives in RAID 0) push data into Premiere Pro fast enough over a single 3Gb e-sata link fast enough to prevent choppy video??
Essentials of the system are:
Asus PT6 SE Motherboard
Intel i7 920 @ 2.97GHz
24GB Ram
NVidia GeForce GTX 580 Video Card (3GB Video RAM)
OS resides on a 500GB Crucial SSD
Project Data on a GSpeed 4-bay eSATA drive. Drive 0 and 1 configured as RAID0 (Drives 2 and 3 are RAID 1 and act as one of two backup locations)
I have run the PPBM 5.5 tests and have the results. As simple as they are, I do not know how to interpret them :-)
"539","81","52","9"
Your thoughts would be appreciated on what insight I can derive from the test results and second, why the heavy duty emphasis on Disk I/O performance when 5MB / sec gets you full HD...
Cheers
Steve

Hi there Jim
Well, I guess “Disk I/O - and 539 is simply horrible” gets nicely to the point The first task is to find out which one since I presume the number combines performance time of Video and scratch disks…
No disk approaches 90% capacity.. so that is out. I do have one drive that is showing signs of getting flaky though it is not one used by PP… Dodgy driver? Hmm could well be.. I have HD Tune Pro..I will run it again and see what it comes up with.
I had an email from Harm echoing your thoughts and he also provided me with a link to follow up..
Thanks for your insight I will let you know what I find..
Cheers
Steve

Flash Video performance is horrible in Internet Explorer 11 & 10 Win7 64bit

Video performance is horrible with Internet Explorer 11 & 10 on a Win7 64bit system.
Flash Player version 12.0.0.70
The video is choppy and stuttering and it's dropping frames no smooth playback is possible.
HTML5 Video playback is super smooth in IE 10 & 11.
ActiveX Shockwave Flash Add On is installed correctly and activated.
ActiveX filtering is off.
nvidia Video hardware (Quadro FX 2700M) drivers are current and up to date with the latest version 332.50
Tested with Flash hardware acceleration on and off = same problem
Tested with Internet Explorer hardware acceleration (software rendering) on and off = same problem
Any suggestions what the culprit may be?

What version of Internet Explorer are you using?

Choppy video playback/loosing frames.

I've had my iMac G5 for about a year and a half but for the 5-6 months i've noticed that Quicktime movies (My quicktime movies that i've made myself and are stored on my hd) can't be played back without them loosing frames or being "choppy" - it eventually catches up - but I may have lost an entire sentence from the person in the video - this happens with any videos I watch - not just quicktime - stuff on iTunes, recordings from EyeTV do this also - not as much - but these are usually Mpeg-2 and are recording in the best quality option possible.
although if i'm watching TV from EyeTV, I have no problem - or if i'm importing video into iMovie - no problems - it's playback that does this.
it's almost as if i'm watching a streaming clip on the internet - with a bad connection. but these videos are mine - saved to the computer.
my iMac is a 2nd generation with the ambient light sensor, and I have 1 GB or Memory - I don't know what else you may need to know about my computer model - but if you think you can help, but need more info - just ask!
thanks.

Choppy video like you describe is almost always caused by too many demands on your hard drive. EyeTV works fine when watching live TV because Live TV is not written to or read from the hard drive.
The most common cause of this would be that your hard drive is too full. For best performance, try to keep at least 15% of your hard drive space free. This gives the computer some room to breathe. If your drive was severely fragmented, it may take awhile before movies will play properly again.
You may have too many programs open. This could cause the computer to use more virtual memory, which increases hard drive usage. In addition, running another disk-intensive program can cause movies to skip.
You may have a performance problem with the drive. If you have multiple hard drives, try playing the movie from another drive.
You may have a filesystem structure issue on a drive. In some cases, these issues can result in poor performance. Run Disk Utility to test the drive. Any number of other common system fixes (repair permissions etc.) may help with this as well.

Satellite C850 - fan is slowing down + choppy videos

Hello
I am here to post this about my laptop fan my laptop is an Toshiba Satellite C850 and it has a i3 CPU core
i know this is not good for gaming
the only games i play is war thunder, minecraft and stuff like that not to big games for top speck pcs but its all i can get at the moment
i also do YouTube and when i am trying to play and record i notice my fan speeds up has normal frames then all of a sudden my fan slows down to 20% percent and i get 5 frames and the videos very choppy
If any one could help me this that would be very nice.
Thanks :)

Hi
From my point of few the notebook slow downs due to CPU overloading and the internal temperature.
Because of the high amount of processes which are running simultaneously, the CPU as well as the GPU go to the limit. The result is an high warmness produced by CPU and GPU and therefore the cooling modules and fan run faster.
After that the GPU/CPU performance will be decreased to reduce the warmness. This process slow down the fan and obviously this affects the video performance.
I think first of all you should check if the cooling vents are free of dust. The CPU and GPU require proper cooling and therefore the cooling grilles as well as fan should be free of dust and debris.
Furthermore I would recommend checking the window advanced power management settings.
There you can modify the cooling mode as well as the CPU and GPU performance.
Last but not least an clean system installation could be helpful too. Why?
Because system might be overloaded by different background processes which slow down the system and lock CPU

Choppy Video on Pavilion 9300t

I had the hard drive on my 9300t desktoop replaced along with a reinstall of Windows Vista 32bit. Since then, I have a problem with choppy video. If I start a video game, video is fine for about a minute then it gets choppy and it's impossible to run the game.
The same thing happens when I try to watch a TV program using Media Center.
I had no trouble with video before the hard drive replacement and Vista install.
I am using a GeForce 9500 graphics card whch had worked fine. It has the latest driver update from GeForce.
It seems that a video buffer is overloading after a minute of video use.
Can anyone help???

Hi,
The specifications for HP 9300t PC indicate it has a 350 watt power supply.
Review this posted document for background information.
These HP 'how-to" articles should be helpful.
The following video cards should work depening on your specific video ouput port requirements:
NVIDIA GT 430
NVIDIA GT 630 --> one of these cards is double width so it might not fit depending on what is in the adjacent slot
NVIDIA GT 640 --> see my above comments about double wide cards.
NVIDIA GT 640
The ASUS GT 440 1GB DDR5 will work with a 300 watt power supply. This is a double wide card but has the best performance.

Slow FPS, graphics and choppy video when connected to a Mini-DVI cable to external monitor on Macbook Mid2007 4GB RAM

Hi,
I have a Mid-2007 Macbook white. I have upgraded its memory to 4GB. Snow Leopard was working great, and I said to myself maybe it's time to upgrade to Lion.
After the upgrade all was well. However, a big problem occurs when I plug in to the Mini-DVI display port with the HDMI adapter, to connect to my Sony LCD HDTV. The whole graphics and video slow down, everything is choppy. Quicktime and VLC video playback is strobe and choppy looks like very low Frame Rate. Cannot watch anything, not HD nor low resolutions. The entire computer is slow when the cable is connected.
Things I tried:
*VGA adapter seems to work fine - it's the digital display output that probably causes that.
*Running it through a new user.
This never happened on Snow Leopard. i'm considering to go back. However, I am wondering if there is a way to fix this minor problem.

Update:
We solved the problem. Weird solution but now it seems to work. I plugged a VGA adpater and played with the screen rsolutions to try and watch a movie well on my LCD screen. I changed the screen resolutions but I couldn't revert back to the default settings. Pressing "Detect Displays" didn't do anything.
Here is the interesting part: When I placed back the DVI-HDMI adapter, suddenly everything worked fine!!! There was no choppy videos, no low fps, works prefect.
Something weird is going on here, but I'm happy I managed to get the DVI to HDMI to work because I was about to removie Lion and bring back Snow Leopard.

Video Lagging/Choppy videos on Macbook Pro

Hello,
I am having a problem while watching videos online: video lagging/choppy videos. Sometimes the video is stuck in a certain frame although I still have the sound on the background; sometimes the video slows down completely (frame+sound). It started around one month ago, and exists in several different websites, I couldn`t solve it by myself. I am not very good with computers. I tried to uninstall/reinstall flash player, as well as disable hardware acceleration, and the problem is still there. Also somedays the videos are working fine, and somedays they are all bad independent of websites. I tried to use different browsers (chrome/firefox/safari), but the problem persists.
I am using a Macbook Pro and bought it in the beginning of January this year (right now it is running OS X 10.7.4) with flash player version 11.2.202.235.
I would very much appreciate if you can help me.
Thanks.

mellskucukoglu, uninstall all adobe products then install Adobe Flash Player, Adobe Reader, Adobe Air, Adobe Shockwave Player. Make sure to select the operating system correctly behind the link. Turn off your antivirus till you finish installation as suggested below the webpage. If it still doesn't work check for OS X 10.7.4 updates.
If it still doesn't work then go for Adobe Live chat in this link http://www.adobe.com/support/chat/ivrchat.html . Sometimes they are busy. If they can't help. Think about any changes that you made before this issue like installaling any new apps. Uninstall them. If it still doesn't work then install Adobe Flash Professional CS 6. After installing check for adobe updates and update them all. It should work at this point. If not ,watch this

Satellite P100 PSPAD: Unable to update BIOS 3.8 and poor video performance

Hello,
I have absolute shoddy video performance on my machine as well as the fan on/off issues.
To add to my frustrations the WinPhlash programme included in BIOS version 3.8 dumps out when trying to flash giving a PHLASHNT.SYS unable to load message with various error codes associated with it (codes 5 and 147 depending on if I run the exe as it is extracted from the ZIP, or run the extracted files independantly).
I have checked all permissionings on the folder and I definately have full control - but still a generic "check your accounts, if you have no permissions please log in again!" message is displayed.
any help with my BIOS issue would be apreciated.
[Edited by: admin on 06-Jul-2007 11:10]

Hi,
I have had the same error message on P100 PSPADE and furthermore the laptop was no longer under control, neither by keyboard or by menu impossible to switch off. I have had to unplug and to remove the battery. Then impossible to switch on.
According to the local ASP the motherboard is KO (??) and the safest way to upgrade the bios was to boot from an USB floppy in DOS mode?
Sounds strange but be careful.

Choppy Video on MEGA 180

Hi all,
I'm suffering from choppy video playback on my MEGA 180. By choopy I mean every ten seconds or so it will freeze up for a split second, the audio stays in sync, but you can slightly tell that the video stops, or skips.
This happens when watching .avi, DivX or even commercial DVD's. It also happens on my screen saver.
Since I was using the onboard video I thought I'd try using a video card but the same thing.
What I can't figure out is what the onboard video and a seperate video card have in common, since it's happening to both.
My onboard video has the latest drivers, and the PC as a whole is up to date.
Any suggestions are greatly needed.
Thanks.

can you give more information on the hardware you have installed in your Mega 180?
and can you give more background information; ie how long have you had this system, has it ever worked correctly, did the problem start after you installed any particular software, etc etc...

Regarding video performance.

Hi,
I bought a MSI P7N SLI Platinum 750i chipset based motherboard Sn. 010B0807485693. After 8 months the board would not post, i.e. no display on the monitor even though the Harddisk LED and the CPU fans would run.
Handed over the motherboard to Microport, they sent it to Smartlink Network Systems Limited RMA Center N.R. Road Bangalore, I had to call up about 25 times to Smartlink and they took one month to give a replacement with the MSI P7N SLI Sn. 601-7380-010B0803214616. Got it on 18/9/2009.
The motherboard which I got from Smartlink is much older, as can be seen from the serial numbers. The video quality, i.e. clarity, color as well as frame rates are very bad compared to the original motherboard that I had.
I now know that the original motherboard never had a problem, only the technician at the Microport, Bangalore shop had delibrately not plugged in the power cord for the 9600 gt graphics card and unnecessarily made me RMA my motherboard.
I want to know if the older boards (of the same model i.e. MSI P7N SLI 750i platinum) used a different technology than the new motherboards have?
Is there a way to improve the video performance on my computer with this older motherboard.
Thanks.

All I can say about it is that, as far as I know, the P7N you got back, shouldnt be slower then the one you send in, they should be identical in setup/build.
I have the P6N platinum and the only difference between your and my board is that yours is able to run 45nm C2Q and has 2, I believe, PCIe 2.0 slots, where as I have 2 PCIe 1.1 slots.
But that doesnt make mine a slow board either, with current setup, see my sig, I have 0 issues or performance problems.
If you can, first try different videodrivers, be sure to delete old ones with drivercleaner or such.
If that doesnt work, might try a fresh install on seperate disk/partition and see if that helps.
But if performance still is bad, I would take it back, in my opinion you should not get an older/slower board back if you rma your new one.

Flash video performance poor in Firefox 3 and other newer Gecko-based browsers; fails to detect mouse movement in full-s

Regardless of configuration, I have found Flash video
performance on Firefox 3 to be severely sub-par. Numerous visual
lags occur throughout a typical Youtube video as it cannot seem to
manage to maintain a steady frame rate. When in full-screen, mouse
movement is not detected, forcing me to click in a full-screen
Vimeo video in order to display its controls when I should have
only needed to move the mouse. I was informed that the technical
explanation for this is that Flash isn't triggering MouseEvents
other than MouseEVENT.CLICK.
In my tests, this behavior also occurred in Flashplayers 9
and 10 as well as with recent versions of other browsers that also
use the Gecko rendering engine, namely Camino, Flock and Songbird,
but not in Firefox 2. I was told by a Mozilla employee that this
issue can only be solved by Adobe.
This has forced me to use the Safari browser as my only
available work-around. I implore that these issues get resolved as
quickly as possible.

guys, im exactly experience the same issue here.. any
solution guys? tks in advantage..
