IPad video buffering issues - playback continually interrupted

I have standard definition video TV shows downloaded to my hard disk. I am trying to watch them on my iPad v2 using Home Sharing on iTunes 11.0.3 on OS X 10.8.3. Buffering is painfully slow, and really limited...it never stays ahead of playback; a 30 minute video takes an hour to watch. Or, would take an hour if I would put up with it.
Would anyone know what's going on? (have searched forums and found lots of similar complaints, but no specific recommendations. I have restarted the iPad.)

Hi sbrindolona,

PreLoader/Slide video buffering issues

Hi I am experiencing problems with my project that uses a mixture of slide video and standard Captivate content. The course preloader displays, the content starts to play then, on a slide video, slide the video will stop and the slide video pre-loader will appear before eventually restarting. I don't think it's a band-width thing because I have tested it on a very good connection and the same thing happens.
What I really want is to get the main course pre-loader to include FLV slide video file size in it's assessment of what has to be loaded - to avoid the FLV slide video buffering and showing its own pre-loader.
Does anyone have any thoughts?
I have tried the solutions offered here http://forums.adobe.com/ but unfortunately this introduced other issues.
Also is there any way of changing the default “loading …” text that comes up when a slide video does need to buffer ?
Many thanks for any help

Slide Video FLVs dont get loaded in the pre-loader. Since the videos could be so large, they are loaded only when encounterted in the project (just when video is being seen). You will usually see a "loading..." message here.
Please try this best practices for frequent buffering problems - Many customers resolved similar problems with it by calculating actual video sizes mathing your network capability.

Trial Version of Elements 10 - video buffering issue

Hi,
I have just tried to work with a small .mov 25 sec video clip to test out this software. It will only play very jerkily but the audio is fine. The software should be compatible with .mov files, so can anyone explain why it won't play the video smoothly please? It seems this software has a lot to offer, having struggled with Movie Maker for the last 4 years, I felt it was time to invest in some software that will enable me to produce home DVDs that are about 1.5hrs long. I was hoping this was the answer, however, now I am already experiencing problems with the video footage, I am getting as frustrated with this as I was with Movie Makers poor performance!

Apple TV buffering issues with iPhone 4s and iPad 2

Hi all,
I just got me an Apple TV 2nd gen (yeah, I know, ordered 2 days before the presentation of the new one). So far so good, the device is up and running, connects just fine to my Airport Express router and all.
However, if I try to stream a video from my iPad (2) or my iPhone (4S), the results are quite horriffic. The iPad videos would buffer for a very long time before they start and then quite fast after that the buffering problems restart. It's pretty impossible to play a video fluently of more than 20 seconds. If I'd try from my iPhone it's even worse with videos being 1080p, the thing just never plays, eventually the preloading process stops on the mirroring mode is cut.
I have to point out, all my devices are in the same room (WiFi) so the signal is the best it can be.
This is honestly quite surprising AND disappointing to be honest, given I bought the device mostly for that, so I can stream videos from my phone and pad.
Tell me, am I doing something wrong, or the video streaming over those devices is just a marketing gimmick with nothing real behind it?
Would it matter if I change my router from Airport express to Airport extreme?
Thanks!

I have the same issue with ATV3 and iPhone 4S. Everything works properly, no buffering issues when watching netflix, vimeo, youtube BUT when I try mirroring even a small 15sec iPhone movie it stutters and buffers and results to a choppy playback..same with larger mp4 files such as 1-1.5GB, buffers forever and never plays, I just re-encoded the same movie to 700MB and plays perfectly..
Why Apple, why?..so close..I can accept the bigger movie files issue, but not being able to playback properly an iPhone movie is funny..I recorded a movie with lower bitrate through Filmic Pro (Economy mode, up to 16Mbps)
and plays properly.
Is there an upcoming software update going to solve the problem or is it hardware related and therefore not fixable.
Please don't reply with a network related answer, by 2012 we know how to set up our networks and everything else runs flawlessly.
I'll apreciate a fast answer, we love Apple, but if it can't play an iphone movie (or a high quality movie from iTunes) it's just not up to my standards.
Thanks again.

Slow/choppy playback - cache buffering issue

On playback, PP6 randomly slows down and plays back choppy on visually complex shots. It takes repeated stops and starts to clear it out. I have troubleshot the life out of this, read every relevant thread, and tried everything imaginable to fix it. Windows 7 pro is fully optimized. There are no software conflicts (installed a drive with only windows and CS6) I’ve got plenty of horsepower - 3930K in an asusp9x79pro, gtx 670 w/4mb, 32mb ram, OC to 4.5. Eric Bowen at ADK has personally tuned the system and done a manual overclock. Memtest confirms the ram is fine. There are no hardware issues. Dropped frame indicator stays green, no dropped frames. Switching from hardware to software mercury playback does nothing. Rendering has no effect, nor do any playback settings. It happens with AVCHD and h.264 mp4’s as well, on short clips, not just long ones. It does not happen outside of ppro. Since I have eliminated hardware and software issues, all this leaves is Premiere.
As Eric explains it, it is a cache buffering issue, related to how the nvidia card and ppro interact, and he sees it frequently enough. I can't do his explanation justice, but he has offered to jump in and provide more detail if need be.
Whatever it is, it’s ridiculous. It is totally unacceptable to play down a sequence and have it intermittently slow down on a system with this much power that has been properly set up by a pro. It’s a shame, because it’s the only thing from keeping ppro/cs6 from being the best platform I’ve edited on in my 12 years as an editor.
I’ve filed a bug report, but gotten no response. If others are seeing it, and can file a bug report, maybe it will be publicly acknowledged and resolved.

Hi,
I think I have similair problem. First of all my current specs is:
Asus Sabertooth z77 mainboard with intel i7 2700K processor
32 gb (8*4) ram
120 gb ssd sata3 drive for OS and CS6
500 gb sata3 7200rpm hd for cache files
1 tb sata3 7200rpm hd for source video and audio
and finally Nvidia GeForce GTX 660 Ti with 2gb of memory
Blackmagic shuttle io card etc
This system were combined specially for my endless highend compositing needs and it works like a charm with all applications other than Premiere Pro.
Yesterday I barley finished editing a short (approx 2 minutes) 1080p project that shot with Canon 5D MKII. Without using mercury playback engine application
works fine but once I activate it all playback became really slow and laggy and sometime it freeze if I move playhead quickly.
I only use one video and one audio track in timeline so we can say this editing scenario is a fundamental for production grade NLE application.
My graphic processor has a lot of cuda power but Adobe doesn't support it natively so I have to edit the famous text file.
On CS5 and CS5.5 I done lots of 1080p project with my old gtx 480 card and I never encountered any similair problem.
I hope my favorite and trusted software company Adobe will find the problem and will fix it soon...
Thanks

I'm having the same buffering issues that other users are having when I try to send a short video from my Iphone 4S to my Apple TV. Has anyone heard back from Apple on this bug ?

Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
Check that both devices are on the same network (Settings > Wifi, on the mobile device and Settings > General > Network, on the Apple TV).
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Restart your router. (Also try removing it’s power cord for at least 30 seconds)
Restart your mobile device.

IPAD Video App resolution issues

the Ipad is reported to have a 1024 by 768 resolution but the video app does not seem to support a frame width greater than 640.
Evidence : I use one app to convert video to MP4 - most of which I can drop into iTunes and then sync onto the iPad, however I got the occasional error when syncing saying that some of the file where not transferred as they where not supported by the device.
after a lot of investigation i notice it was all the MP4s with a frame width greater than 640.
Further investigation leads to the fact that the Video playback on the iPhone is limited to 640 - presumable its the same app on the iPad
question 1 : when will the iPad Video app be upgraded to use the native resolution of the device
question 2 : is there a third party video viewer that supports its full resolution

MPEG-4 videos are indeed limited to 640x480 (as stated in the specs for the iPad). Try H.264 instead; that is supported up to 720p.

Best ressources for "ANDROID vs IPAD video issues"

Hello
Would someone be kind enough to post here the best ressources for the "ANDROID vs IPAD VIDEOS issues" ?
I got lots of troubles to have some videos working on Samsung Galaxytab ...

Sorry but what is the definition of "inline" videos, I wanna be really sure (i'm not english / in my language my videos are "inline" videos: videos put inside the document).)
On some apps I made, some videos work, some don't. And
one of the main issues are
- they launch full screen when they're not supposed to (i want them to launch in a definite area)
- they dont launch full screen when they're supposed to (when they're suppposed to play in full screen, they just do not appear: black screen)
mmm ?

HT2729 Video syncing issues between new IPad and Macbook

I used my new IPad to film some videos for about three months. Today, I connected my IPad to my Macbook in an attempt to upload the IPad videos to my Macbook ITunes. Unfortunately, the IPad synced with my computer files, and all of my videos were erased off of my IPad. I cannot locate them anywhere on my computer. How can I recover these lost videos? Please help! Thanks!

Try this first.... Quit iTunes, restart the Mac, restart the iPad and then try again.
If that does not work, look here for more help.

Youtube 1080p buffering issue

My iPad mini retina always buffers when playing a 1080p video on youtube but my nexus 7 2013 plays videos just fine in 1080p how do I fix this?

Yes I get the same issue on my iPad air with the YouTube app.
I'll be watching a YouTube video and every 30 seconds or so it will degrade to a lower quality for a few seconds, then the HD will come back on.
I have 160 Mbit internet and this does not happen on the desktop PC.
I loaded an alternative YouTube player onto my iPad and there was no such issue, so the problem is the official ipad app - its fantastic, but playback is poor recently, for some reason.
What I have noticed is that the video does not seam to load ahead at all, there is no grey bar loading the video ahead of playback anymore.
I think the app needs fixed.

Apple TV (2nd gen) - Very Specific Buffering Issue

I have been watching the threads regularly for a situation similar to mine but I can't see one so I am starting a new one.
I have Four (4) Apple TVs in the house and a large library of movies, TV shows and personal movies loaded into iTunes on a Window 7 64 bit system with an Intel i7 processor, 12 GB of memory and 2TB of disk space. Everything seemed to work OK until I got the third Apple TV but that was a year ago and several software upgrades in the past.
My problem is that when all four (4) Apple TVs are plugged into power, even if the ones I am not using are asleep, I have horrible buffering delays when watching vidoes from iTunes on the Windows PC. I do not have any trouble streaming video from Netflix or the iTunes store directly. When the Apple TV stops to fill buffers it seems to lock up trying and never comes back (I have waited up to 30 minutes). However, if I exit out of the movie as soon as the buffering issue starts, and go back into the video where I left off - it starts playing again within 3 seconds and will carry on for another random period of time in the range of 2 minutes to 10 minutes.
Before anyone starts responding with the basic stock suggestions, I am a retired IT guy who has put a lot of time and technical effort into trying to find the root cause of this problem. I am very familiar with networking, Windows 7, firewalls, etc.
The work around is that when I want to watch videos from iTunes on my Windows PC I have to unplug the other three Apple TVs, restart my router and reboot my Windows PC. These three steps together work consistently but omitting any one step may or may not improve the situation. This means that I can't just decide to watch a video from iTunes without 10 minutes of advance prep work - and watching two different videos on two different Apple TVs at the same time only works about 30% of the time.
Here is some more background information:
I have two (2) iPhones, one (1) iPad, another Windows 7 64 bit PC, a MacBook Air, and stand alone Internet radio on my network. The problem persists even when all the other devices have been powered off.
All devices, including the Apple TVs, are running the most current version of software and have ALL patches installed.
I have upgraded my router (twice) and now have an ASUS RT-N56U dual band router with the Windows PCs both cable connected and the Apple TVs and all the other stuff running wireless.
I have used netstumbler to detect other networks and have tried various different channels on the router. I am in a low density area and only see two other neighbours with wireless networks.
I have a 20 MB Internet service connection via cable modem and have no problems watching videos on the Apple TVs from the Internet
I have relocated the router away from any other elecrical equipment (Apple TVs all show a full strength signal)
I have tried disabling my MacAfee Security Center virus and personal firewall software (the problem persists), then removing it entirely (the problem persists), then reinstalling only the virus protection component and enabling Windows Firewall (the problem persists).
I have removed all software from the Windows computer that brand name commercial software - I use Microsoft Office 2010 and Google Chrome as my browser (the problem persists).
Important - I have moved the complete iTunes library to a 2TB USB hard drive and run iTunes on my MacBook Air with the Windows PCs turned off (the problem persists).
There is one issue that seems relevant, but might just be a bug in the router management interface. I have set up reserved DHCP addresses for the Apple TVs and the computers to make it easier to identify devices when I am troubleshooting. The DHCP log shows the correct IP addresses being assigned to the correct MAC addresses but the network map screen frequently displays two or more Apple TVs with duplicate MAC addresses. It only happens with the Apple TVs and has never happened with anything else. This is what gave me the idea to turn off all Apple TVs except the one I want to watch and reset the router to clear the other addresses - which seems to be the only consistent way to watch an iTunes video without buffering problems.
Any ideas would be greatly appreciated. I have invested a lot of time and money in Apple technologies and setting up this home video strategy. It's very frustrating that it doesn't work reliably.
Thanks
Bob T

I too am having this issue were two of my Apple TVs are showing duplicate MAC Addresses. I have varrified this by looking at the arp -a cache on multiple machines. I believe this is a major bug in the Apple TV software. Can we please get a fix.

Apple TV 3 Buffering Issues using Ethernet

I have an ATV3 that is connected via Ethernet with Comcast Xfinity. I have 30+ dl speeds but am constantly having problems with buffering It seems to be only movies bought through Apple. HBO, Showtime, ESPN, Netflx, etc. all seem to work with minimum buffering issues. I reset it, restored it, brought it in to Apple and received a new one and nothing seems to help. It is set on automatic for IP address, for DNS, and for video playback. Any help would be appreciated.
Thank, Tony

Those other services use adaptive streaming, iTunes content is fixed rate and needs to load a portion before playback begins. Comcast have been known to throttle iTunes/ATV traffic. Try testing on another network (preferably a controlled one like Apple's)

Youtube App buffering issue?

Hello, my iPad Air (Wi-Fi only Model) has been having issues with the Youtube app recently, and I want to see if anyone else is having any issues. My issue comes down to the iPad Youtube app being unable to buffer certain videos. It's a really strange problem. This problem started about when 7.1.1 came out, I believe.
I will watch a 30 minute "Let's Play Minecraft" video from Rooster Teeth/Achievement Hunter at 720p without any issues. Then, watch a four (4) minute music video and throughout that short video, the quality will change from 720p to 240p and keeping changing throughout the video till it's over, but the video never stops playing.
I ran a speed test with the OOKLA speed test app. My ping is 21, with a Downoad rate of 39Mbps, and an Upload rate of 11.5Mbps.
Strange thing is, my iPhone 5 will play the videos that I have an issue with on my iPad, just fine.
So, is this an issue with the iPad Youtube app, or could something else be happening?
Thank you in advance!

Yes I get the same issue on my iPad air with the YouTube app.
I'll be watching a YouTube video and every 30 seconds or so it will degrade to a lower quality for a few seconds, then the HD will come back on.
