Video playback terrible!

I've just bought one of the brand new MacBook Pros (March 2011) which has it's own dedicated graphics card and 8GB Ram but still I find that HD video playback within Aperture 3 is unwatchable.
It starts and stops and if it works is very jittery.
Is this just how it is in Aperture?

For what it's worth, I think the problem I was experiencing was because my video files were stored on an external hard drive connected to an Airport Extreme and I was trying to play those HD videos over wifi (which presumably isn't fast enough to stream HD video)

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I know the iBook and G4's in general are very outdated today, but I need to ask anyways.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.

Video playback on mobile device

Hello,
I'm new here and probably this was asked before me, but I spent a lot to search on the net and actually couldn't find much.
I'm developing a web based application dealing with video - it should be controlable and have to interact with other elements of the app. The client now asks mobile apps - for Android and iOS, that should have same features.
I looked for solutions to play video on mobile device using Flex and building mobile apps but nowhere could find a proper explanation and results about framerates and performance. The other problem I think will be that the mobile device should play streamed video (which can be encoded in any suitable format) as well as native video - usually h.264, that as far as I understood, is not possible on iOS (I coudn't find out about Android).
On my Android device I can play very smoothly even web videos (in the browser) that are not "optimized for mobile" as it pops up during playback. I made a test and build a simple app that just plays a remote video using the Spark's VideoPlayer and its framerate was OK but the picture was terrible - some strange coloured lines appeared.
Is there anybody who has more info about video playback on mobile device, codecs, components etc. I need that info to make the choice to stick with Flash development for all the apps or to go for native development with platforms' SDK.
Thanks

Can you say even more about what it is you want to do? I mean, what will the application do, not what are the technical aspects of how it will work?
For a point of comparison, look at this thing I did:
http://www.cartoonnetwork.com/mixit/
If you try out the Make page, both the template ones and the from scratch one, as well as the View page to see the playback unit in action. Is what you're going to do anything like that?
I have tried the playback part of this as a mobile app, and it so very nearly works ok! Amongst the many problems are that the overall data rate needed is quite high, and mobile devices aren't as consistant or high bandwidth as desktops, the external swfs often need code in them, so that rules out iOS, and to do the layering involved rules out H.264.
At some future time there will hopefully be StageVideo that can use H.264, but I don't know when that will be, or whether it will be responsive enough (FLV is much faster to connect to and play than H.264).
Incidentally, even in the Objective-C world you can't lay things on top of the standard iOS H.264 player. To do that you have to use the AV Foundation class, so it's fairly low level programming. Using FLV in Flash is a lot easier!

Video Playback Issues after Downloading iTunes 10.4.1 & Quicktime

After downloading v. 10.4.1, video playback framerate is terrible. Voices are choppy & out of sync with dialogue. The music wasn't necessarily affected but, can here slight distortion. This hasn't been an issue until downloading the latest software version. Then iTunes crashes. Am I the only one this is happening to?

You may consider updating your iTunes to the latest version to fix bugs.

Playback problems - Video playback stops after 1 second (CS5)

Hello forum,
i recently got huge problems with video playback. The video stops playing after rougly one second and the last frame freezes. After that, Premiere won't show any frames when scrubbing through the sequene. It just shows the freezed frame and the whole program just becomes terribly slow.
Sometimes the playback is just fine, but in some cases the playback error occures randomly. I experienced that the error happens even more frequenly when Flash Player plays back a video in the background, e.g. a youtube video.
Maybe the playback errors happen because my harddrive is almost full (1,5TB capacity, 300 GB left)? Or is it because of a few plugins ( e.g. filmconvert)?
I run Windows 7, Premiere CS5 on an I7 860 2,8 Ghz quad core CPU with 8 GB of RAM and a nvidia 460 GPU.
Thanks for your help.

sounds like a major shortout. you can take it in, but this isn't going to be good news, I'm afaird.

Need help fixing video playback on iTunes and worried it will affect iphone

First of all, the black levels when playing videos on iTunes looked terrible.
I looked all over on how to fix this..
So then I installed the lastest nvidia graphics drivers to help with video playback
After install my videos black level was definatly better, I think.
But now all videos play wierdly in the corner of the itunes program..
http://img36.imageshack.us/img36/8170/ituneshelp.png
I need help to fix this and I hope this dont affect playback on iphone 4

If exporting to i4 results in the same, there could be a problem with the movie itself. Try exporting to the i4 and replay the video. However if exporting to i4 plays okay on the phone, it's your Nvidia drivers. You can download the prior Nvidia drivers and downgrade.
There have been dozens of cases where Nvidia drivers even the newest ones have made a mess of games, movie playbacks, even viewing Windows programs.

Are you having iTunes video playback problems?

Do you have iTunes Store-bought videos whose playback is terrible, all choppy and full of freezes while playing back in iTunes?
Have you copied one of those iTunes videos to a thumb drive and had it play back perfectly?
This problem is not fixed by any of the Quicktime adjustments that Apple suggests on their "how to fix video playback issues" page, and, aside from this video playback issue, iTunes is working fine on my machine. As I said, the videos work fine, too, if played from a thumb drive instead of the hard drive.
This has been going on for weeks, and people have been posting about it here on the forum, but, to my knowledge, there's no fix. Just silence.
It might be useful if people who are seeing this problem post some information about their systems. For all I know, all of us who are seeing this problem have one particular vendor's computer.
The computer I am having this problem with is a new HP laptop that came with Vista. This one:
http://h10025.www1.hp.com/ewfrf/wc/genericDocument?docname=c00846935&cc=us&dlc=e n&lc=en&jumpid=regR1002USEN
1.6 GHz AMD Turion ™ 64 X2 Dual-Core Mobile Technology TL-52
2 X 512KB L2 Cache
2048MB DDR2 System Memory (2 Dimm)
NVIDIA GeForce Go 6150 (UMA)
120GB 5400RPM (SATA)
I think the problem has to do with SATA, but I don't really know, except that my computer has it and I am able to play these videos perfectly from a thumb drive but not the SATA hard drive.
If you are having this problem, please consider posting your computer's info. Thanks.
HP Pavilion Entertainment PC Other OS Vista

OK, I figured it out... I too have a dv6000 with Vista and I have been trying to fix this terrible itunes video playback thing and this is what I found. For whatever reason the NVidia driver in the dv series doesn't play nice with Vista. They say that they are looking into it but have no response other than that. Somehow the data from the hard drive isn't fast enough. So, reading this I figured that if that REALLY is the problem that I could use a external drive and have the videos come from there, and Voila!! It works like a charm, no skipping, no stalling, no more blue screens. I hope this is helpful, I know what a pain this can be.
ALSO, apparently some think that you can't watch itunes video while using Vista's "ReadyBoost". I haven't had that issue personally, but I have seen a lot that have who disabled it and had it work fine.
Let me know if this works for everyone else.

ITunes Video Playback - Sound skipping

Hi - Just bought a new PC and have installed iTunes and brought over all my sound and video files to it via iPod hard disk function. Music is playing perfectly. All video playback is accompanied by terrible stuttering and spluttering of the audio. This is occuring at all times - even if iTunes is the only app running. DVD playback fantastic on PC as is video playback using other apps. Videos i'm trying to play are all under 5 minutes long and differ in type from video podcasts to Pixar content bought from itunes shop. New PC has brilliant spec so don't understand - any suggestions? All help much appreciated - regards!!

I almost have the same problem with the Video Podcast the sound is bad, For the audio only it works perfectly. At first everything was in order and worked well.
Then for no reason I got the trouble with the sound of the Video Podcast there was echoes and the quality was poor.
Cause it’s new computer I re-installed everything, so it worked well again. Then after going on a web site that uses active X for animation I got the problem back. I have no idea if Active X QuickTime are connected but each time the pattern the same.
Have tried to re-install iTunes the Quick Time I have changed the Audio option about filters in both nothing helped.

Can't hear recorded sound during video playback

I take a lot of videos of my kids. I have noticed lately that the volume is low or muffled...you can't hear what is being said even if they are screaming 6 inches away. I thought maybe something had gotten into the microphone, etc. I recorded a voice memo and on playback i could hear what was recorded just fine at a normal level. Now once I tried to record a video of my kids talking, it played back so low that i can't hear anything and that is with the volume turned wide open. Not really sure what this issue could be but if the volume works fine on voice memo wouldn't it work the same on video playback?

ITunes / Windows Video Playback.. (what, you actualy want to WATCH vid's?)

I'm sure there are several people out there that are having the same or similar problems, but because I can't seem to find them with the exact problem I'm having, I thought a new thread would be appropriate....
Upgraded from 6 to 7 yesterday... music seems to play OK (not as good as 6, but not all the issues other people are having). Now video playback in iTunes is little more than a slideshow with audio to (almost) match.
When I go to play back any vid podcast, or other video in my library for that matter, iTunes bumps my processor up to 100% and holds it there, and the video does little more than skip and bounce through the entire playback (even if the overlay controls go away fully, the slightest mouse movement brings them back). The audio quality seems to almost follow the video, but they get away from each other (the audio was about 2 seconds ahead of the video/slide show while watching the current version of Photoshop TV). Any other video player works fine, but if I wanted to use them, I would have never installed iTunes in the first place, the idea being that the integration was the blessing.
I USED to be able to watch a video, use Photoshop CS2, have Flash 8 open behind it, After Effects running on a seperate monitor, browse the web, and play freecell all at the same time, with several background utility style apps going all at the same time with out a hickup.
After trying the IDE fix's, the sound setup fix's and any other fix's found in the discussions (and yes, reverting them after they failed to fix the problem), I'm still having an issue, and now I can't find iTunes 6 to try to get back to a good time in life... oh why oh why apple, why do you have just as many issues as windows? I had hoped for so much more....
Anyone? Any Ideas? Anyone willing to email me itunes 6 so I can get back to a better time in life? Or provide answers? I've got a horriable track record with apple (over 20 business stopping questions, and to date 0 responses) so I am about 2 minutes from giving up
Sorry apple, but this is way past frustrating... were all your win/tel beta testers using mac's?
HomeBuilt Windows XP Pro ATI 9700 Pro / AMD Athlon 64 3800+ / hampster on treadmill running his head off...

Are sure that's not Flash needed for those videos?

How can i monitor network traffic to debug video playback issues from a NAS?

I am having problems playing videos on my new Mini that i am using as an HTPC.
I have a brand new Mac Mini running Lion with a 2.7 i7 processor and 8GB of RAM with a wired connection to a switch. .
My switch is a NETGEAR ProSafe GS108T-200NAS set to default settings. I haven't had a chance to start messing with VLAN settings or anything else. There is a bit of a learning curve on my part on this end.
My NAS is a ReadyNAS Pro (RNDP6000) with 3 x 1 TB hitachi ultrastar (HUA722010CLA330) drives and a 1.5 TB seagate (ST31500341AS) drive setup in RAID config using X-RAID2.
The problem I am having is video playback when accessing large video files off of the NAS. These are typically 1080 HD mkv files.
I have tested movies as small as 7.5GB with only slight stutters on occasion. I tried a 10.5GB movie and the stalling was much more pronounced. Movies larger than 11GB are completely unwatchable stalling every minute or so.
I have also tried large movies on the local drive and that is not a problem at all - they play back just fine. Beautiful playback in hidef. Mind you, some of these are the same files that were stalling over the network.
I have also noticed that some other network devices get kicked off the network when a movie is playing.
I think it has something to do with the transfer speed of files over the network and the switch - i am no expert at this mind you.
I am wondering if there is some sort of utility that i can use to monitor network activity on the mini so that i can fix my problem. Or has anyone made chages in their switch settings to optimize data trasfer speeds.
Any advice or recommendations on.
Thank you all!

OK, I did a couple of things and ran things a couple of times.
First what I did settings wise:
I enabled jumbo frames on the Mac Mini, ReadyNAS Pro, and the Netgear GS108T switch. All with MTU set to 9000.
I went ahead and enabled jumbo frames on the rest of the computers on the network just in case.
After these changes I ran into the same problems with videos timing out - very annoying and frustrating as you can imagine.
Then I started playing with device configurations. My original configuration was NAS > Netgear switch > Mac Mini. I went ahead and switched the switch to an Airport Extreme I have as my WAP and the setup looked like this - NAS > Airport Extreme > Mac Mini.
Well, long story short, no go. It appears to me that the NAS is the one having issues providing the necessary data at the proper speed. I also tried playing sopme movies off of the NAS onto a desktop i have and had the same issues - choppy frames and crashing movies. I even tried connecting wirelessly to see if that would work.
BTW, I have the Mac accessing the file system using CIFS.
I don't know what else I could do.
I am going to have to go to the Netgear forums to see if i can figure this out. Hopefully, I can get things going to be able to help some people out.
If anyone has any ideas, they would be greatly appreciated.
My only other alternative is spending $2000 for the thunderbolt capable NAS that Apple sells - it's only money!

Apple TV 2 choppy video playback when mirroring from Macbook Pro (Yosemite) and Macbook Air (Yosemite) but not iOS devices

Video playback is choppy (cuts out every 30-45 seconds) when air playing from both my MacBook Air 1.3 GHz Intel Core i5 running Yosemite and my husbands new MacBook Pro, but runs perfectly when mirroring from any of our iOS devices (iPhone 6+, iPad mini 3, etc.) We have Apple TV 2. This problem just started a few weeks ago, was working fine around Christmas. The problem seems to have coincidentally started right after our son tried plugging in and setting up his Chromecast on our tv. I disconnected the Chromecast, but we still have the problem. All of our software if up to date and I've tried disconnecting blue tooth, we do not have a microwave and our wifi network has a very strong signal. We have an Airport Extreme base station. Is there a solution to our problem?

Hi leahmturner,
I see that you are experiencing an issue with choppiness while AirPlay Mirroring from your computers to your Apple TV. I have an article that contains some helpful troubleshooting steps for you regarding this issue:
About AirPlay Mirroring in OS X - Apple Support
http://support.apple.com/en-us/HT201343
Optimizing image quality
Resolution matching modes
You can choose between two desktop resolution matching modes that let you select which display will have the best image. When AirPlay Mirroring is turned on, select an option under "Match Desktop Size To:" in the AirPlay Mirroring menu extra.
Match Desktop Size To: Apple TV
AirPlay Mirroring changes the desktop resolution to best match your Apple TV, resulting in a 16:9 image that fills the HDTV screen. This setting often produces the sharpest image on the HDTV. The aspect ratio and/or resolution of the built-in Mac display may change to accommodate the Apple TV.
Match Desktop Size To: This Mac
AirPlay Mirroring scales the contents of the desktop to fit on the Apple TV, leaving the resolution of your Mac's display unchanged. Use this setting for the sharpest image on your Mac's display. Depending on your Mac model, the resulting image may not fill the HDTV screen.
Troubleshooting AirPlay Mirroring
If you don't see mirroring options
If your Mac and Apple TV are on the same network, but no AirPlay Mirroring menu appears, your Apple TV may be asleep. Simply press a button on your Apple TV remote to wake it up. After a few seconds, the AirPlay Mirroring menu extra appears. If you still don't see the options you expect, make sure your Apple TV has the current software update installed. Also make sure that you have the "Show mirroring options in the menu bar when available" option selected in the Displays pane of System Preferences.
If the menu bar or Dock is cropped
Some HDTVs have bezels that cover a small percentage of the screen. This can result in a slight cropping of a full-resolution HDTV image. Depending on the HDTV model, AirPlay Mirroring may automatically adjust the picture size to prevent cropping. If you are using OS X Mountain Lion or later, and you see cropping of the menu bar or Dock when using AirPlay Mirroring, toggle the Overscan correction option in Displays preferences.
Minimize video post-processing
HDTVs often apply picture quality enhancements intended to improve the look of film and video sources. In some cases, these enhancements can lead to over-sharpening artifacts when displaying your Mac desktop. Some HDTV models have built-in settings to change or disable the enhancements for use with a computer (computer, presentation, or game modes). Otherwise, the controls for sharpness, detail enhancement and noise reduction can be used to optimize the appearance of the Mac desktop. Consult your HDTV’s manual for guidance on the appropriate settings for use with a computer.
Firewall security settings
If you use a firewall, make sure the following firewall security options have been set to allow AirPlay Mirroring to work:
Choose System Preferences from the Apple menu ().
Click Security & Privacy, then click Firewall.
Click the lock icon to unlock it if it's locked, then type an administrator name and password.
Click Firewall Options.
Deselect (uncheck) the “Block all incoming connections” checkbox.
Select (check) the “Automatically allow signed software to receive incoming connections” checkbox.
Thanks for coming to the Apple Support Communities!

Braden

Video playback from Final Cut Pro studders over HDMI

I have a problem playing back video from FCP. The video output will studder during horizontal pans when I output via HDMI. The audio output is not affected.
I have been playing video successfully using FireWire for output in FCP, however, my new video switcher system will not support FireWire output.
What are some possible causes of this problem?
System stats:
* Mac Mini (2010 model)
* 8GB RAM
* OS X 10.6.4 (Snow Leopard)
* Final Cut Pro 7.0.3 (Final Cut Studio 3)

@ Studio X : The files were originally created with Final Cut Pro, rendered out to QuickTime, then are being played back with Final Cut Pro. The file that has the most noticable studdering is a 60-minute timeline sequence in Final Cut. All files are being stored and played back from the Mac Mini's internal hard drive. Everything was originally shot on DV and formatted for a 4:3 aspect ratio.
@ Shane Ross : Are there any settings in the MacOS or FCP where I can improve the HDMI video signal? Or do you know of / have any experience with Firewire to HDMI converters? Unfortunately, my new signal path relies on HDMI from the video playback.
My current setup uses the Firewire output, which is then converted to composite video & analog audio using a pair of ageing DV tape decks. That setup is becoming troublesome due to age.

Video playback terrible!
