IOS 4.2.1: Intermittent Playback and Static Issue Resolution - JVC KD-AVX77

Hey guys, it appears that iOS 4.2.1 fixes the issue with the intermittent playback and static issues that I was having in my car. I just played two songs continuously with no issues.
I have the JVC KD-AVX77, and with iOS 4.1, I was having nothing but problems with music playback. It had got to the point that it was intolerable to use my iPhone in my car.
I am extremely pleased that it seems like Apple took everyone's feedback about this issue, and came up with a fix to it. Too bad that I've already stored my car for the winter.
Please post your own findings. I know this issue was across multiple head units and car manufacturers.

Same problem here. I have a 3gs and this intermitent static/hiss/lag happens when i connect through the usb on my toyota prius. This problem did not happen before the latest software upgrade. I have switched out the cables. Also tested on an ipod touch without the software upgrade and had no problem. It's a crazy annoying problem! Sounds a bit like listening to vinyl. I have also tried switching to airplane mode, but that didn't do anything. I have also reset the iphone while connected to the usb (the same way i frequently have to because of an earlier problem i've had with the usb failing to work in the car at all...) and that has not fixed it. I'm going to try connecting via bluetooth today and see what happens - i'm guessing that will be fine, but i don't like to listen via bluetooth.

Playback and render issues Premiere Pro CS6 on Mac

I have been having very "skippy" and sluggish issues when it comes to playback and editing. I have deleted all the old render files from my project and my hard drive, but nothing seems to work. Can someone please help me? I'm not sure if it is a space issue or what, but I haven't had much of these problems before. I know it's not a sequence settings issue, so I am very confused. My footage all comes from a Maxell P2 Eseries card and my computer specs are:
iMac
Processor 2.5 GHz Intel Core i5
Memory 16 GB 1333 MHz DDR3

Premiere Pro CS5 Playback and Performance Issues

I upgraded (2) separate editing work stations to CS5 from CS4 about a month ago. I moved from 4 to 5 to try and get rid of some problems which both work stations were encountering.
The problems since the upgrade are similiar: playback from timeline has intermittent audio drop out and video going to black during playback, (new one)-video locked up but audio kept playing-system hung and had to be rebooted.
Also, when clicking around on the timeline or scrubbing the timeline, Premiere crashes.
This type of performance on playout or timeline usage is consistent on both machines which have indentical setups and builds. None of this happens all the time but happens enough to causes problems with workflow. We edit on the work stations, dub files to playback system for air, and use a shared server to move files back and forth as needed but files are always stored locally instead of using straight from server.
These machines are:
Premiere Pro CS5.02
OS WIndows 7 Pro 64 bit
12 GB Ram, DDR3-1333 (6-2GB modules)
CPU Intel Xeon Quad Core [email protected] GHZ, 2 processors, 8 MB Cache
500 GB SATA 2 hard drive, 7200 RPM, 32 MC (System Drive)...309 GB of space avail
(3) 1 TB SATA 2 hard drives, 7200RPM, 32 MC (3 TB, RAID0 STorage) 2.16 TB of space avail
Nvidia GE Force 9800 GT Graphics card, DUAL DVI, 1 GB
REaltek High Def Audio, Drivers 6.0.1.5953
(1) monitor in use
output of system runs to ADVC-700 breakout box to feed playback system
I have all of my software installed on C: (309 GB of 500 GB avail)
I have all of my videos files stored on D: (Raid Storage with 2.16 TB of 3 TB avail)
The only changes I've made since installing CS5 would be to change the auto save from 20 minutes to 60 minutes. Don't know if an auto save would cause an issue on playback as I've noted above.
I'm not a computer whiz by any stretch of the imagination but I can follow directions if given for testing/eval.

Do the PPBM5 Benchmark and send the results to me by PM, in addition to sending the results to Bill as indicated. I'll have a look at what might be going on here.

Playback and Rendering issues when GPU acceleration is enabled

I'm using the new MacPro with dual AMD FirePro D300. When I enable GPU Acceleration (Open CL) I can no longer play through an entire sequence. It specifically has issues playing through any layered graphics or titles, but seems to play with those disabled. I have tried having "Composite In Linear Color" enabled and disabled, and neither seemed to make a difference. It's the same deal when rendering. If I have titles, and use GPU Acceleration it jumbles clips, cuts to black or static, all manner of weirdness. Is there something I'm missing?
An example of what playback looks like if I have titles and GPU Acceleration enabled.

This computer thing seems complicated enough that if your system works better with GPU accel off, that's you best performance. I understand they've been trying to sort out these sorts of issues but there's so many dang variables, and trying to build software that interlinks with other complicated software is something no other NLE or Grading program does. That throws even more kinks into the list.

Premiere CC 2014 playback and rendering issues

Definitely having problems that I wasn't having just a couple of days ago.
Timeline, 4 minute music video mainly7 all on V1 and then V2 with just a few short shots overlayed using opacity/screen. I use this technique a lot and always worked more than fine in Premiere CC.
So, I made some minor changes today. Select in/out on entire project and hit render in/out.
First thing I notice is the progress bar keeps jumping back and forward; ie - 20.0% then 19.8% then 20.2% and so on (two steps forward one step back).
Then noticed... I hit render and it says rendering 1 of 20 previews... ie 500 frames. Then it gradually changes... 1 of 21 previews 510 frames.. 1 of 22 previews 520 frames etc etc and etcetera... and basically never end... just hangs around 98.8% until I was waiting for over half an hour for something that would usually take seconds in the previous version. I keep having to hit cancel on the render.
Then, I look at the render bar on the timeline.. all is green (zoomed in, no yellow anywhere).. hit play and it pauses for a split second here and there. Completely randomly. Also certain shots just completely freeze.
I didn't have any of these problems in the previous version of CC and at present it's not suitable for client playback. Nowhere near it.
Any updates?
Thanks

I selected the entire project that was completely rendered and hit render and it did 0 of 2 frames 1 video preview.. then 4 frames 2 video previews up to about 50 previews. Eventually looks like it has rendered. Hit play and the video clips its pausing on are now completely green shots. Not had this on PPro or CC before. I have a Quadro 2000 and usually runs perfectly. In fact there is not chance of it being my card. It's definitely to do with the update.

Premiere Pro CS6 - playback and C300 issues

Hi,
I seem to be having an issue with Premiere Pro playback.
At the moment, I'm looking through a rough assemble I've done on a PPro sequence and then the playback will start getting choppy. The only solution seems to be rebooting PPro, which is obviously very frustrating. The footage is C300 files, stored on my RAID. Why is this happening?
My system details are as follows:
MBP early 2011, 16GB RAM, 512 GB SSD
6TB Pegasus R6 RAID connected via Thunderbolt
30" ACD
Mac OS 10.7.4 , PPro 6.0.1
I use a 2-screen setup, so the 30" monitor will have the PPro tools and seq etc, whilst I use the 17" MBP screen as a viewing monitor.
Another issue I had which is more annoying that anything is that when I imported the rushes from my C300, PPro decided to import a fairly long (80") interview as loads of separate .MXF files RATHER than joining them together, which FCP seemed to have no problem in doing...How do I sort that out?
Thanks

I am having precisely the same problem as bricklaneeditor, and have exactly the same setup: MBP early 2011, 16GB RAM, 512 GB SSD,
30" ACD, Mac OS 10.7.4 , PPro 6.0.1
Indeed, a restart of Premiere Pro always fixes the problem -- for a while. I've also seen similar behavior in Media Composer 6.0.1 once or twice so am wondering whether it's an issue with this machine/OS, as the playback software architectures are so different on those two NLE's.
I should also mention that the problem is not isolated to any particular file format -- have seen it with timelines containing 7D footage, HDV and ProRes files.
I strongly suspect some sort of problem on either Apple's or Adobe's end with the GPU in this machine, as it is ATI and not Nvidia -- and is, as far as I know, the only non-CUDA GPU, at least on the Mac side, certified to work with the CS6 Mercury Playback Engine.
Also wondering whether an over-the-top or a clean install of Mountain Lion might shake things up enough to make a difference. (Otherwise I'm in no big hurry to upgrade my OS.) Is anyone seeing this problem with PPro under 10.8? Might be worth installing 10.8 over an external HDD clone of the System drive and booting temporarily from the clone just to see if the problem persists in Premiere.
Anyone have any thoughts on these possibilities?

IMovie Playback and import issues

OK. Been having issues with iMovie here lately. First it was the playback, very choppy and the video would freeze up (audio seemed unaffected) made it real hard to edit previous projects. This started after a QT update. I hit the boards and tried everything suggested by you good people.... still having issues. Now , just today I tried to import some footage to a new project and it imports 3 to 4 seconds of choppy video then simply stops importing all together. Could this really be a QT bug that Apple needs to fix?... because nothing I do seems to rectify the problems. Using iMovie HD, and a Panasonic miniDV cam (which I have been using to import for years now).

Apple have not acknowledged a problem with Quicktime 7.0.2 and OS 10.3 but they have provided a download to go back to 6.5.2.

please can give any advice on the problem with the download

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Video playback and other issues

This might be a 10.6.4 issue or it could be hardware, I'm not sure.
*First Issue:*
Oftentimes, when I try to play video on my Macbook (stats included) the video hangs up and the audio skips like a bad record (remember records? ). This problem is particularly bad when playing videos from the internet but it persists even when the streaming bar is fully loaded in the browser. I took an online masters course this summer and constantly had this skipping issue so I thought it was Adobe and Apple not playing nice since their videos were Flash based. Now, I can see that the problem also occurs when trying to play Quicktime videos. I made an iweb site with a few videos and my Macbook can't seem to play them. However, when I go over to my Mac Mini it has no issues and it has the same processor in it and less RAM.
I know what your thinking; 'check the activity monitor.' I do check the activity monitor, constantly. When this problem occurs I'm never using more than 50% CPU and I usually have at least 1 GB of RAM available although the problem has manifested itself with a much as 2 GB of RAM available and minimal CPU usage.
This issue is starting to get worse and I've had a few kernal panics lately, which may or may not be related.
At the beginning of the summer I reinstalled the system from scratch to see if that would solve the issue; no such luck.
I thought is was the RAM so I tested it with Techtool Deluxe. No problems found with the RAM.
Now, this issue might be related to the second issue but I'll let you decide.
*Second Issue:*
This issue has been around for a long time and I've largely ignored it since all the forums I've been on don't know what to do/can't pin it down.
The issue is that the fan runs constantly at a high RPM no matter what I do.
Again, I check the Activity monitor consistently and I have it set so I can view "All Processes." No 'memory hogs' running.
I also have smsFanControl running and set for 1800 as the min speed.
Furthermore, my wife has the same model computer (only manufactured later) and hers runs whisper quiet while mine sounds like a wind tunnel.
In fact, as I type this I have 1.29 GB of RAM free, 97% of my processor is idle and I'm running at 65C with a fan speed of 6200 RPM.
Any thoughts on either of these two issues would be a help. Thanks

DaddyPaycheck thanks for the info. I am have 7 GB of RAM and my internet access is through cable. I never had this problem before with an older computer with the same internet connection. I am not sure what to do. I recently upgraded to the 30" monitor and a new video card. I purcheased another video card, the ATI Radeon X800XT, but I haven't installed it yet. I am not sure that this will fix my problem. I have all the latest updates for Quicktime and Windows media player. I actually does it when I am playing DVD's as well.

Intermittent copy and paste issues...

I've been running into problems with copying from MS Word (Office 2004) into Mail. What happens is I can copy and paste from word once, then after that, no matter how many times I try to copy and paste other selections from word, I can only re-paste the original selection.
Closing and restarting Mail doesn't seem to help, neither does closing and restarting word.
It seems that using Onyx to clear the cache helps, but the problem sometimes comes back... any ideas?

How are you copying/pasting? I have just tried to reproduce the problem, using menu items (Edit/Copy in Word, Edit/Paste in Mail) and couldn't. I copied 5 separate sections of text, all from the same document.

FCP playback and exporting issue

Hi, I'm having an issue in FCP where as I'm playing it, all of a sudden a picture will go really wierd - i.e. the colours will be bright blue and pink, and the picture showing will not actually be the correct image, but one from somewhere else in the timeline.
If I just hide and re-show the subtitles that are above the image, the picture is back to normal.
I thought it would just be a problem in FCP, but it also occurred when I exported using best quality in compressor.
This issue only started occurring when I started making some changes to the subtitles (there are a lot in the film) - but I don't see how that could affect it.
I also thought maybe it could be to do with the fact that I have 6 video tracks (made up of subtitles, captions, etc.)?
If anyone knows anything about why FCP is doing this, and how to stop it, I would greatly appreciate your help.
Thanks

IOS Music Player MP3 Gapless Playback Problem

Hi,
I've been having this gapless playback issue on iOS now for the past few years, since at least iOS 6 if I can remember correctly. The number one reason I use an iPhone and iOS devices is for gapless playback in the iOS music player. For the last few years I've been experiencing a bug with the stock iOS music player on my iPhone 4S using iOS 6 and on my iPhone 5 using iOS 6 & 7, and currently on my new iPhone 6 running iOS 8.1.2. This only happens on my iPhones and using iOS, this bug is not found when I use my iPod classic or when playing the same albums through iTunes.
I thought it might have been spotted by other iOS users and fixed in iOS 7.1 or at least the current version of iOS 8, but instead it's gotten worse, albums that used to play smoothly between transitions now suddenly pause and jump for a split second when changing from track to track.
What's happening is, I listen to a lot of albums that are continuously DJ mixed and play straight through without any pauses between tracks, and I've been experiencing problems a lot now with random split second pauses between tracks and choppy transitions. These albums in question have been ripped from cd using the latest versions of iTunes.
For example,
I'd be listening to an album and it would play gapless and smooth for most of the album, but maybe one or two transitions on the album would have a split second pause between them, and the rest of the album would play perfectly with no pauses, skips or jumps at all.
This only happens on my iPhone, as I have a 160gb iPod classic and I've listened to all the same albums on it and never has a problem playing the album without any pauses, every album plays 100% smooth and gapless on it.
I mailed Apple about it through their feedback page on their site... https://www.apple.com/feedback/iphone.html
Hoping that they would take note of this and try and look into it and fix the issue. That was probably about a year ago now, never got fixed or got any confirmation back from them about this problem. Then last August, I'd had enough and contacted Apple support to notify them about this issue. They told me the usual story, "have you tried restoring the phone?", which I obliged and did. The problem was there on a freshly restored iPhone 5.
So they told me that they would put me in touch with someone higher in Apple to take the case further, "great" I thought.
I spoke with a senior care advisor and explained the problem and agreed to send detailed explanations of the issue and test files too so that they could hopefully hear what I was talking about. But after a few weeks of going back and forward, I finally got them to hear the issue with the random pauses, the first week they denied there was a problem and said the files played ok on their test iOS devices, so I myself tried the files on another iOS device and the same problem was there.
The last correspondence I had with the Apple care advisor was back in the end of August / start of September, and she told me that they spotted the issue and was told by the tech's that it would be fixed in a future update, I never got a when this would happen, I was just told to make sure my iOS device was up to date with the latest version of iOS. I couldn't speak to an actual technician, got no follow up support, just a vague "We'll look into it." Case Closed.
I got so sick of this problem that I sold my iPhone and iPad just after this last phone call with the Apple people, and switched over to Android. I'd being reading up on gapless playback music players and found out that there's a good few available for Android devices. I got myself a Sony Xperia Z3 Compact, twice as powerful as the iPhone 6 and half the price. I was using that for the last few months, and playing my music through Neutron Music Player app which is a great music player which plays gapless 100%
But I couldn't really take to Android OS, seeing as I've been using Apple products for around 10 years now and iOS since the iPhone 3G. So I decided to contact Apple again and see if they'd fixed the music player issue in iOS yet.
I wrote a long email explaining the problem, how it wasn't really looked at properly, and how I was a long time Apple customer and had to resort to switching over to Android because the basic music player functions on iOS devices have bugs. I took a chance in mailing this to Tim Cook's offices, I knew he wouldn't reply personally, just thought that it might get read by someone in his offices with a bit more say in the matter.
Just before Xmas, I got a call from someone from executive relations from my local Apple offices about this. He seemed nice and was aware of the problem from reading back through my emails and previous case notes from August when I opened this case originally.
We had a talk and he said he would get one of the tech's to call me too about this so that I could explain the bugs to someone more knowledgeable about iOS.
A few days later I received a call from one of the tech's at Apple and was chatting to him, explaining the problem. His response was that he thinks Apple doesn't support gapless playback on current iOS devices. From looking at the gapless playback information page on the Apple support site below, it looks like it hasn't been updated to show any iPhone models after the iPhone 3GS... http://support.apple.com/en-ie/HT201644
I was trying to explain to him how ridiculous this sounded, why would Apple stop supporting basic functions on their music player on iOS devices? It makes no sense at all? You can see that the amount of hardware devices and software that supports gapless playback today... http://en.wikipedia.org/wiki/Gapless_playback#Player_support
He couldn't explain either, he just said that because it's not listed there on the Apple support page.
Then the next day I got the follow up call from the Apple executive relations guy, he was stating that he was speaking to the tech guy that called me and it looks like Apple doesn't support gapless playback anymore, from looking at the documentation on site.
I told him how stupid this was, and how lots of music players have gapless playback as standard today. And if they don't support it now, then why does it play through some parts of the albums on iOS ok and then just randomly pause, or have jumpy / choppy transitions on the rest of the album. If it was the case, no albums would play gaplessly at all, it would be like when the first ever iPod's were released back in the day with no gapless playback and would pause for a split second between every transition.
He couldn't give me an answer and said that maybe down the line they would start supporting it again, and that I should request the feature to be added to future iOS versions via the iPhone feedback page... https://www.apple.com/feedback/iphone.html
He just kept on emphasising that it was "NOT A BUG OR ISSUE", trying to cover up the problem because the info on the site wasn't updated to show the current iOS devices. Which in itself is wrong, looking at the page it says "Supported iPod and iPhone models (make sure you have the latest iPod or iPhone software)"
iPhone, iPhone 3G, iPhone 3GS only go up to iOS 6, so that contradicts itself when the latest version is iOS 8.
The info is out of date and needs to be updated. So in August I was told, "we found the issue and will look into it" and a few months later, "it's not an issue", what's a cop out.
I was annoyed and taken back by this response, and really found it hard to believe that this was the case, Apple stopping supporting their music player on iOS devices. Seeing as iTunes plays everything smoothly and no gapless issues. I just went out and bought an iPhone 6 for €900 / $1060, and for that money you'd expect it's basic music player to work. It's total BS to think that a top computer software / hardware company would just decide to abandon basic functions in their devices, especially when we are talking about how much Apple takes pride in their products and how much more they charge for them over their competitors.
So this is my next step to try and get this problem seen and out in the open more. The more people who know about it and are aware of the issue, the better.
Hopefully more people can get the word around and get this noticed by Apple and finally fixed.
I've uploaded some test files below to show the problem. The files are mp3's and aac, and have been ripped from cd using the latest version of iTunes. The mp3's are the ones with the issue, but the aac play with no problem. If you listen to the transition at the end of track 2 (2-02 Colours (JH Re-Edit)) going into the start of track 3 (2-03 Your Body), you will notice the split second pause / jump. But listen to the aac version and compare it to the mp3 version and you will hear that it plays back fine, just as it's supposed to. Try them in iTunes too and both versions playback fine, no jumps or pauses.
You can download them here, all links have the same files, I just uploaded them to different hosts for other people's choosing...

https://www.sendspace.com/file/lubcmc
More files can be provided if needed to show the problem happening on various other albums.
I really hope that people can spot this issue too and help get this fixed, I know this gapless playback feature might not be important to some people, but like I said at the start, it's an essential function for me in a music player and I use it on a daily basis when I listen to music.
Thanks for reading this long rant of mine, appreciate it.
Ger

I believe this issue occurs only between songs that iTunes has converted to a lower bitrate for you during transfer to your iOS device and songs that it has not done this for. Take this Between the Buried and Me album, for instance. I have marked all of the transitions that should have been gapless but probably aren't in red. I know for sure that most of these marked transitions are indeed broken and that the most of the transitions not marked in red work flawlessly... I honestly can't remember whether or not some of these transitions were gapless or not, but the many transitions I do remember working or not working match up exactly with whether or not the songs on either side of the transition were also on other sides of the 256kbps threshold, the threshold at which I enabled iTunes to convert tracks to 256kbps AAC.
I'm going to try re-sync'ing my library with that "feature" disabled and see if it fixes my gapless playback problem. Will post the results once I test it out.

Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
