Poor 1080p Video playback

I have a 2008 iMac with the upgraded 4GB Ram and 512Mb Nvidia video card - I recently received a GoPro Hero3 video camera that records in 1080p@60fps and higher resolutions. Once I download them to the iMac into iPhoto or iMovie the playback is ridiculously slow and choppy.
I have also recently noticed issues with my Time Machine Backups and finding they take much longer then before.
This feels like an issue that I would get from my old Windows PC. I have about 50% space left on my 500GB hard drive and I am not over using resources while attempting playback of the videos.
I have no issues playing them on a Dell laptop though?
Any thoughts on how to fix this issue would be greatly appreciated!
Thank you in advnace.

Based on numerous threads I have read, many others are experiencing poor video playback. Evidently it is a 10.8.2 bug because one individual posted that they got a beta version of 10.8.3 and the playback problem had been fixed.
Only guess I've read about the 10.8.3 release date is sometime in January.
File a bug report - it can't hurt:

Even though it may not do any good I would suggest you run Disk Utility/Repair Permissions. Repeat until it shows no repairs were made. Clearing the log in between runs can make the process less confusing. It would eliminate permissions as a possible problem.

1080p video playback disappears

When I try and play a 1080p video on my computer that I purchased through iTunes, it plays for a second or two, and then the screen turns black. The audio continues but there is no video. How can I correct this? I am running Windows 7 professional, Intel Core i5 @ 3.1 GHz, 8 GB RAM on a Dell P2212H monitor with native resolution os 1920x1080.

I would suspect third party video codecs (components) that may have gotten installed over the years.
A dual 2 GHz machine is also at the "low end G5" for supported playback on any 1080 format.

Poor hd video playback

Hi, I have a Intel Core 2 Duo 2.16 with 2 gb ram, snow leopard, and am having trouble with hd video playback, mostly with quicktime. Video is slow and jerky, like it's skipping and hanging on frames.
I certainly have enough hardware for it because my bootcamp XP has not problem with it, and iMovie can play it back easily as well. I can't say when it first started happening, but definitely after upgrading to Snow Leopard.
Please help so that my only conlusion isn't that microsoft's 11 year old OS is better than this.

Update: I downloaded VLC last night and it works fine. Mostly the problem seems to be with Quicktime, and most of the videos I am testing come from my iphone 4gs. I say most because some vid play just fine in QT.

Poor movie/video playback from mini Mac (2010) to 50 " lg LCD tv

Hi I just got my new mini Mac 2010 release and have it set up running through my 50 inch full 1080p LCD LG tv.
It's running through a Belkin hd cable from mini Mac to the tv and get great quality from picture desktop on 1080p setting on the Mac.
However when ever I watch a DVD,movie from iTunes through front row the quality is terrible and get "blocky" picture in dark parts of the movie.
I love my new Mac but this is driving me crazy I have tried calibration and changing the settings on my tv.
Please any help with getting better quality playback from movies on my Mac as the picture is worse than an old vcr

Welcome to  Discussions!
Have you tried using DVD Player instead of Front Row to play the DVD?
I do hope you realize that a DVD is not HD quality. Because DVDs are lower resolution than your TV, when you play them full screen on your TV without an upscaling player they are not going to look as good as they did on your standard definition (SD) TV.

Poor H264 video playback

Constant motion jitter/stuttering is observed in h264 content
played back within Flash Player. Behavior is seen during both local
and online progressive download playback and is NOT seen during
playback using other players capable of h264 playback such as
Quicktime Player and VLC. It is NOT related to CPU load.
Same behaviour is also found on different platforms: windows,
macs, firefox, IE, safari etc.
Here's a webpage with more info:
http://www.sabandcom.com/H264/index.html
And a sample 360 camera pan showing the jerkiness:

Hope someone from Adobe can look into this and verify the
bug.

Update: I downloaded VLC last night and it works fine. Mostly the problem seems to be with Quicktime, and most of the videos I am testing come from my iphone 4gs. I say most because some vid play just fine in QT.

Poor quality HD video playback when in full screen?

I've recently purchased a late 2013 iMac 21.5" mid-range model and finding the video playback quality poor when opening it up to full screen. Does anyone else have this issue?? I was expecting similar quality to my HD tv when using the iPlayer app, but i@m even finding it poor when watching the HBO trailer on the Apple website for Game of Thrones. I have also been into my local Stormfront and found the same issue on both their 21.5 and 27" models on the shop floor.
Am I being too picky? The quality when it is in the small window is amazing.

The quality when it is in the small window is amazing.
One thing that pops into my mind is: what is the resolution/size/quality of the video you are watching? If it was created in a smaller size, then forcing it into showing on a bigger screen will always impact the quality significantly. You cannot enlarge a picture or video without significant quality loss (fuzzy/pixelation).

What QT7 settings do I use to export a 1080p video for playback on iPhone4? I'm using the iPhone to playback 1080p video on 1080p monitor. Is this possible?

Does anyone know what settings I should use to export a 1080p video for playback on iPhone4? I'm hoping to use the iPhone4 to playback 1080p video on 1080p monitor. Is this possible?
I have previously saved my .mov file as Apple TV, but the quality is reduced from 1920x1080 to 960x540. I was unable to sync the higher quality file to my phone (and am worried this is the limitation of the hardware). I added this file to iTunes, added to a playlist, and sync'd to my iPhone. The playback works but the resolution is obviously a lower quality.Is it possible to keep the higher quality for playback through a 1920x1080 hd monitor? Otherwise, would I be able to sync a 1920x1080 mov file to a new iPad or other device? Thanks in advance to your answers.

No. Only the iPhone 4S, iPad3, and TV3 currently support 1080p30 content. Even then the 1080p30 playback support for your monitor may depend on how the device is connected. The iPhone 4 is limited to 720p30 playback.

Not on your current device. As previously stated, the latest generation of iPhone, iPad, and TV devices support a maximum 1080p30 playback capability but may be limited to lower resdolutions depending on your method of connection to your monitor. This information can be found on the Apple web site TechSpecs page for each respective device.

YouTube App Video Playback Poor Performance

Not sure when or what changed but video playback performance on my iPod Touch 4G when using the YouTube app has been very poor the last couple months. Used to work just fine. The performance has been so bad that I basically gave up watching YouTube videos on my iPod. By bad performance I mean it would literally take 10 minutes to watch a 2 minute video (estimating of course). And I would get chunks of about 20 seconds before I had to wait while the video would buffer again.
I know this is due to my connection speed as video playback using the YouTube app at other locations that have a faster speed still worked fine.I think my home connection is up to 5 MB download but I actually only get around 4 MB. But still, this should be just fine as it used to work. Also, NetFlix and FaceTime work just fine at home. The YouTube app should be able to determine the video quality based on your connection for streaming. But it now longer seems to do that.
Talked to Apple tech support and they had me reset my iPod which did not help. But they had me try using Safari instead of the YouTube app. By using Safari and going to YouTube.com video playback on my iPod Touch was just fine. Videos would buffer more quickly then they would play. Even if I left HQ on, video playback was fine. Go figure? Something definitely seems wrong with the YouTube app.
So I thought I'd post this in case anyone else was searching for a solution. This works for me.
Seems like the YouTube app needs to be updated. Mentioned this to Apple tech support but was told Google would be responsible for that and they doubt it will be done due to YouTube no longer using flash. Hmmmm, the app seems pretty integrated into iOS as the app comes installed and can not be uninstalled.

See:
iOS: Troubleshooting applications purchased from the App Store
Try when connected to another network to help determine if it is a network problem
Contact the developer/go to their support site if only one app.

Poor video playback with Windows XP

Hi all,
I am trying to play TV shows that bought from the ITMS (Xena & Star Trek remixed originals). I seem to be getting poor video playback performance. The video is briefly freezing and skipping. The frame rate is also not very good.
System specs:
2.6GHz P4 with hyperthreading enabled
2GB RAM
Matrox Parhelia 128 video card (latest drivers and firmware)
Soundblaster X-Fi Platinum
WinXP Pro SP2 + latest hotfixes
iTunes 7.2
I bought my first TV show after upgrading to iTunes 7.2 so I can't compare performance with v7.1 or earlier. I've tried playing the videos from a local IDE (D:, 60GB free out of 120GB) and from my 1TB Buffalo Terastation (RAID 5, 750GB). The performance is the same. The CPU activity varies from 75% to 95% CPU usage while playing the videos.
Even though my Matrox Parhelia is 3 years old it is still one of Matrox's top performance video cards and does excelent 2D and pretty good 3D.
Any help will be appreciated.
Thanks,
Steven

You're leaping to a conclusion that isn't supported by any facts. Just because you are having a problem is not an indictment of Safari 4. I'm having no trouble, nor are millions of other users, so that destroys your thesis. The problem is something that was a pre-existing condition on your Mac.
Did either of you Repair Disk Permission before and after installing it? If not, start with that. Do you have the most recent version of Flash installed? If not, download the Flash uninstaller from the Adobe web site, then the lastest Flash installer and run those, then restart Safari and test it on some video.

Why is HD video playback quality poor?

When I play YouTube high-definition (720 or 1080) videos in Firefox in full screen mode, the play back is blurry compared to Internet Explorer; the same video, the same resolution - just a different browser. Why is this happening and what do I need to change in Firefox to get the same crisp high-definition video playback that is available in IE?

Isolate. New user (follow http://support.apple.com/kb/HT1199). Safe Boot (follow http://support.apple.com/kb/HT1455). Test to see if Quicktime has the same issue by watching videos at http://www.apple.com/findouthow. Is your Flash player up to date? Visit http://www.adobe.com to check. Let us know.

Poor video playback in Encore 2.0 preview and monitor window . . .

I'm having a strange issue with my video playback in the preview and monitor windows. At some points it displays as blocks (like digital noise). I unchecked the "Automatic" option in the A/V Output dialog as described in the manual. Still, nothing changed.
To make sure it was Encore that had the problem, and not the file, I played my MPG2 files through PowerDVD, and nothing wrong with the playback in there. What is Encore 2.0 doing? How can I fix this problem???
Any help would be appreciated!
Thanks!

What Mouse drivers are you using please?
This might sound silly, but under 1.5 (Different preview engine, true, so this may be completely wrong) I found that with a later revision of the MS Intellipoint drivers, I had exactly the same issue.
We worked this out by realizing the green blocks appeared as soon as the mouse was moved. As with your cases, the discs still burned true proving it is a preview related issue.
Uninstalling & reverting back to version 4.1 made it all go away.
But since the preview engine is now the PPro one, this might not work any more.

What is the best Compressor setting for best quality video playback on an iBook g4?

I know the iBook and G4's in general are very outdated today, but I need to ask anyways. I have some video projects in 720p and 1080p in which I have down converted to 480p and also exported to MPEG-2 for DVD (personal wedding videos and videos made for my clients using Final Cut Studio). Anything encoded at most resolutions using h264 won't play on my iBook. Even 480p.
I have about 20 hours of mixed video content that I need it in a format that is suitable for an iPhone 4 and an iBook 12" with a 1.2GHz G4, 1.25GB RAM and I added a 250 WD 5400 IDE hard disk (running 10.5.8 and 10.4.11 for Classic Mode). I know the iBook doesn't seem like the best tool for modern video playback, but I need to figure out which setting will play best with iPhone 4 and iBook so I don't need to make 2 local copies of each video for each device.
The iBook plays best with the original DVD output MPEG-2 file and playing back in QT Pro or VLC... but I already have 180 GB's of MPEG-2 files now and my little HD is almost full. I don't have enough room to convert all the iPhone 4 counterparts. If I use Compressor 3.5.3, what is the optimal setting for iBook and iPhone .m4v or .mp4 files that can play on both devices? So far 720x400-480 widescreen videos @ 29fps works great on my iPhone, Apple TV 2, and other computers but seems to murder my poor iBook if encoded with high profile (and still choppy on simple profiles). 640x480 (adding black matte bars to my videos) plays fine in MPEG-2 but drops frames or goes to black screen if I convert it to mp4 (and looks bad on the iPhone 4 because of the matte). But if I convert on any of the simple profiles, it looks terrible on my iPhone 4 and a blocky on the iBook.
This is the problem leading me to having 2 copies of each video and eating my hard disk space. What is the best video setting for both playback on the iBook and iPhone 4? Can the iBook playback H264 at all in decent resolutionsat all? I don't really want to have a 480p .m4v collection for the iPhone 4 and a MPEG-2 RAW collection just to play the same videos on the iBook.
Any suggestions are greatly appreciated! Thanks!

Update: The iBook can play any 480p video and higher if I encode them with DivX and in AVI format. But of course this is not compatible with my iPhone 4. At least I can shrink my library now and get away from the full MPEG-2s. I don't get why I can't use Apple's h264 though. There has to be a setting I am missing. The sample Apple h264 videos from the days of Tiger worked flawlessly on my iBook when it was new so the CPU must be capable of decoding it. I really can't understand this.
Also, since I made my videos in English for my family, I had to create soft subtitles for my wife's Chinese family, and I can't get players like QT with perian or MPlayerX to sync them properly to an AVI encoded with DivX, they only sync well with the iPhone 4 m4v/mp4 formatted files I made. This is a real pickle.
So now I may need three or four copies of each video, LOL. I need to hardcode the subtitles if I want to use AVI to playback on older machines, and keep the mp4 file for the iDevices too, while keeping higher quality h264 videos for my American relatives...
If h264 is compatible with my iBook, what is the proper encoding settings? Must I dramatically lower the settings or frame rate? I can settle on 2 copies of each video that way. One iBook/G4/eMac compatible video that syncs correctly with my srt soft subs, and another version that works well with my iPhone 4 and iPad.
All in all, I will end up with more than 3 or 4 version of each video. On my late G5 dual core I have the full 720-1080p uncompressed master files. On my i5 iMac I have the h264 compressed versions for distribution, and lower versions for my iDevices. Now I need to keep either full MPEG-2 files for the iBook to play, or convert to older formats like DivX AVI for our family's legacy machines. I am running out of hard disk space quick now, LOL.
Is there an easier way?

Video playback--mba 2010 w/mountain lion

Has anyone noticed terrible video playback on 13" 4Gb mba 2010 with the mountain lion upgrade? Youtube using flash (11.4.402.265) at 1080p is unwatchable and 720p is barely watchable at full screen. Connecting to a larger monitor is much worse. I could do all 3 when I had Lion. I'm not running any other applications at the time and used the app Free Memory to clear the RAM cache before playing a video. I've tried firefox, chrome, and safari (which I prefer), and they all had similarly poor results. I previously used html5 on lion, but those gave me choppy results and found flash to be better. Any suggestions?

I tried unchecking "enable hardware acceleration", but the results were similarly poor in safari 6 and chrome. However, while using safari 6 on youtube, I opted for the trial html5 setting and it now plays 1080p smoothly at full screen. Hopefully, this might helps others struggling with the mba 2010 processor.

S540 HD video playback lags

Hello,
I have a brand new Lenovo s540 laptop.
There is a problem with HD video playback. 1080p and 720p video playback is laggy. Each 2-3 seconds it gets frozen for 0.2 - 0.5 seconds. I have downloaded all latests drivers from Lenovo web site (except bios update, does it make sens to update bios?).
It didn't help.
OS is windows 8.1 64 bit, all updates are installed.
Also, have tested my PC using 3dmark tools, it shows very poor results - 2 times less than their "Ultralight notebook" reference.
Would you suggest, how to fix this?
Thanks

my config is: i7, SSD, 8GB RAM, intel HD Graphics and Radeon HD 8600M

Slow video playback in Photoshop Elements 11

Playback of videos directly in Photoshop Elements Organizer is very slow. Video is stuttering.
Playing the same video outside of PSE11 with Windows Media Player is much better. Video plays without any stuttering.
Looks like the internal video player of PSE11 is very poor and provides slow performance.
What can I do do have the same video performance with the PSE11 player as I have with WMP.
I use Windows 7 64 Bit (8 GB RAM) with a Intel Core i3 (2330). This CPU has enough power to playback HD or Full-HD videos without any stuttering!!!
Why can't the internal play of PSE11 Organizer play my videos without stuttering - like WMP 12.0.7601.18150 does?
Regards,
Dodson65

The videos I use are created with different devices.
I have HD videos taken with a Pentax DSLR and I have Full-HD videos taken with a Windows Phone 8 device.
Both playback on my Laptop without any stottering with different software. I checked WMP and VLC. Even when using my Laptop with energy-saving profile these videos can be played without stottering.
When I playback the videos in PSE11 Organizer I don't want to edit them - just playback. So why should the internal player behave different? I agree with you - this might be different when I playback the videos in Premiere Elements 11 (as this is a video editing software). But when using Photoshop Elements 11 I want to be able to playback videos in the same performance as I can do with WMP or VLC. If Photoshop Elements 11 can't do that - why? The organizer of PSE11 is not an editor. It should be able to playback videos the same way (with the same performance) as other players on my laptop.
Can you please explain this sentence: "Have you started a Premiere Elements project yet that uses this video's specs? This will often trigger Premiere Elements to download the necessary components for interpretting the video." Is there anything I can do to improve video playback performance?
