Having Canvas Playback Problems

Hello,
I'm a professional user of Final Cut Express 4. I'm currently working on a video that is relatively simple. I have a LiveType title that crossfades into a series of interview clips with color correction filters on them. There is an mp3 file playing underneath all of this. This is no different than any video I've done before, however I cannot get more than 30 seconds of canvas playback without it getting choppy and then cutting out completely, even when rendered.. The footage is from the same camera and same SD card as before. The only thing that I can think has changed is that I have installed Adobe After Effects since completing my last video. However, I uninstalled it thinking it would help with the choppy playback. It did not. I tried lowering my rendering settings, but it still didn't work. Is there something I should be looking for?

I figured it out. I accidentally had a bunch of hue filters on one of the clips that was slowing it down. But I took your tip on AIFF. Thanks.

Canvas/playback problems

The canvas is playing back my newly captured footage really badly and not stopping when I press spacebar or press stop in the canvas. When I view the footage in QT it's fine but in the canvas it looks wierd, its kind of slow and jerky. Do I need to change the FPS or something?
Also, the audio is behind the video. so I need to move the audio tracks every time to match the video. Is there a simpler solution to this?

also make sure you have unlimited rt turned off if you don't have a fast computer sometimes that can cause the canvas to chug along cause it can't keep up with all the video thats going on on the screen. also if you are just doing rough cuts turn the quality of the canvas down for editing so it isn't as processor intensive.

Playback Problem with Tascam Interface

Hello,
I am new to Logic, and I seem to be having a playback problem. After a quick search, I realize this question is asked a lot, but I have yet to find a solution that has worked. I am using a Tascam US-144 USB 2.0 Audio/MIDI interface with Logic Pro 8. Logic is recognizing the interface, allows me to record, and even displays the wave forms that my microphone picks up. However, I cannot monitor while I am recording or play the recording back after saving it. I've attempted to do this with the built-in iMac speakers and headphones. I've tried various output combinations, read the manual front to back, but have yet to find a valid solution. Any help would be greatly appreciated. Thanks.

In the About Logic window it says it's version 8.0.0. I checked Preferences->Audio->Devices->Core Audio. The"Enabled" box is selected, and the US-144 is selected as the device. There doesn't seem to be a tab in that window to select an output. On the bottom left of the screen under "I/O" I have Input 1 selected as the input and Out 1-2 selected as the output. Do I need to select a different output in that tab, or do I need to change it elsewhere?

Song playback problem

On my 8gb nano I've been having a playback problem. A song will start playing and then stop. The nano will then skip to the next song. If I try to go backward to the begining of the song that wouldn't play, the nano skips over it and goes to the song that played before the song that wouldn't play. What can I do to troubleshoot or fix this problem?

Hi Wille_ecj!
You might need to reimport that song(s) into your iTunes library - or, you could try to play it in iTunes. And, if you are prompted to find the source of the file on your computer, try locating it.
If you can't locate it, just delete it from your iTunes library, then reimport it back in.
If this is a song that was purchased from the iTunes Store, however, then try and see if the techniques in this article help with that issue:

Why am I having imbedded video playback problems in Lion?

Hello all,
I'm been having problems viewing web videos on my 2011 MBPro 13'' w/ OS X Lion. Any time of web video I have normal sound by the video frames get all jumpy, almost like its less than 1fps. The only web videos that do not have this problem is when I watch a youtube video on youtube.com. If I watch imbedded youtube videos, I have the same skittish video playback problem.
I have my adobe flash updated and I used Google Chrome as my web browser.
Anyone else have a similar problem? Fixes? Thanks!
-Sean

Two things to keep in mind
There is a forum for Lion, another for MBP owners, and this is not.
And yes you will find lots and lots of threads of same.... no one looks at those that were "Solved"

FCP 6 playback problems in Digital Cinema Display on an LCD External Monito

Hi
Looking for advice.
I am running FCP 6 and have hooked up my Macbook Pro to an external LCD SAMSUNG Flatscreen TV. I want to preview my edit as I cut but Im having problems with playback.
When I hit play the video freezes on the one still image on the LCD, The canvas windows is playing fine but the LCD playback doesnt move... is this a setting/resolution problem?
Im editing in DVCOPRO HD which i thought may be the issue but even when I switched to editing Jpgs or even DV PAL sequences it still does the same thing!
On some occasions BOTH the canvas window and the LCD dont move at all, only when I turn off the External LCD Cinama Desktop Display monitoring does the canvas window play normally.
Can anyone help with my problem?
Im editing on a Macbook pro 17" 2.4 ghz 160GB with a NIVIDIA 8600 Geforce graphics card 256MB 2.0GB RAM running Final Cut Pro v.6
cheers

I was having a similar problem trying but was set up with a 17" viewsonic as my primary monitor (menubar location) and my MacBook Pro as the secondary. I wanted to play back Hi-Def full screen on the MacBook Pro and all I got was still frames (though I could advance a single frame at a time and see motion).
I didn't find an answer here but went exploring in prefs and found a solution that worked for me.
In System Settings > Playback Control I changed "RT:" from "Safe" to "Unlimited"
Now I'm happily watching the full resolution HD video on my laptop screen.
I'd be curious to know if that works with the Flatscreen TV.
All the best,
Kevin

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...

http://www42.zippyshare.com/v/37047710/file.html
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.

Iphone 5 video playback problems over quicktime?

ive recently got a new laptop, pre windows 8, and downloaded quicktime pro in order to play my iphone videos right side up because windows media player will play them upside down alot of the time. something i immeadiately noticed was that all my videos from my iphone 5, when played back via quicktime, have a big judder/skip in them every 2 seconds whereis all my iphone 4 videos playback no problem. the few videos i have that are recorded right side up from my iphone 5, because of orientation of the phone during recording, play perfectly fine on windows media player so this this leads me to believe it is a quicktime issue. i have updated to the latest quicktime just a few days ago with hopes of it being corrected but no such luck. im curious if anyone else is having this same problem or knows a fix? also if anyone knows how to flip videos with quicktime so i can just watch them on windows media would be great also. i found a write up how to do it but everytime i try it, after i save it it just reverts back to its orgional orientation. thanks for any help, Jamie

Add me to the list of people having this problem.
I'm running Macbook on 10.5.8. Quicktime is 7.6.9, in case this has any bearing on things.
OK......I just searched a few places and came up with this:
http://en.wikipedia.org/wiki/Perian
It's called Perian, and it's one of a few different options you could use to solve this problem....I just installed it (free), and now the videos play without a hitch. It's a plug-in for Quicktime. There are others that can supposedly do the same thing--look around and give it a shot.
(Also, supposedly this Perian is no longer in open development, and may not work with the newest Quicktime update for the newest Macs, but, like I said, there are other options out there that may work for you instead.)
I have a feeling my problem may have been due to my particular Quicktime/Macbook setup being a bit outdated, but who knows?
Good luck!

Bridge CS4 - MP4 preview playback problem

In Bridge CS4 on Windows, the preview playback of MP4 files sometimes works and sometimes it does not. If not, Bridge shows only an icon in the preview pane and there is no preview start button.
I have sets of MP4 footage that work OK, but other sets can only partly be previewed. Another strange behavior of Bridge is that in some cases after changing the file's name, the program suddenly does not show the preview anymore.
Is there anyone else having the same problems?

Read this thread, especially post #19 and see if it solves your problem. http://forums.adobe.com/thread/652660?tstart=0
All MPEG files are not the same so just becasue one play does not mean they all play.
If changed files do not show up purge the cache (tools/cache/purge cache) and let it rebuild.

This content requires HDCP for playback problem! Apple TV2

Owned Apple TV for two weeks. Two weeks ago, everything was fine for films already in my iTunes library.
This week, when selecting play on a movie, I get the message 'This content requires HDCP for playback problem' inconsistently. Some vids work, some don't. Then they do then they don't! I have tried on a Samsung TV and a Sony Bravia? Same for both!
How do I resolve this. I have tried different HDMI ports, turned Apple TV 2 off and on. Tried different cables (Although my HDMI cable is the one I purchased from Apple).
Any suggestions? Is it something Apple need to fix? This is kinda embarrassing when I tell friends how good Apple TV is, get them round to watch a movie and inconsistently get this.
Many Thanks for any help
Dave.

I too sadly have this handshaking issue. I'm in Phoenix, AZ. Day one buyer for ATV2. Worked all of about two days in terms of streaming HD content from either my MAC or netflix. About the third time i tried to stream HD content from Netflix or Blu Ray digital copies from my Mac, I get the HDCP compliance message stating my display is not authorized.
I have tried every concievable combination of unplugging and rebooting of TV (Samsung 2005 DLP), ATV2, and HDMI switcher (Monoprice) and nothing will work. My DirecTV HD-DVR works like a charm. If I rent an HD pay per view from DirecTV, no problem. If I rent an HD movie on iTunes, won't display it due to the HDCP issue. I've NOT ONCE had an issue with my DirecTV HDDVR having an HDCP compliance issue and of course its connected to my TV via HDMI thru my monoprice HDMI four port switch.
I guess the only other thing I could try is exchanging the unit itself. But everything else works as advertised. It feels like this is just a software issue that needs to be patched, and fast.

IPad 5.0.1 update video playback problems

HI is anyone else having playback problems with videos on IPad 1 after 5.0.1 update???
As in the playback not atcually working at all???

See if any of the following Videos 'fixes' work.
Try searching for the name of one of your videos on the iPad's spotlight search screen - swipe your first homescreen to the right, type in it's name, and if it finds it tap on it to see if it plays.
If that doesn't work then try closing the Videos app completely : from the home screen (i.e.not with the Videos app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Videos app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
A third option if the two above don't work is a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Audio playback problems in Safari since Mavericks upgrade

I've been having intermittent audio problems in Safari ever since upgrading to Mavericks on my iMac.
Google Play Music doesn't make any sound at all in Safari. Works fine in Firefox.
Downloading audio clips/mp3 playback in Safari has intermittent clicks/pops & sounds terrible.
Tried installing latest version of Flash player...no help.
Everything used to be fine before upgrading to Mavericks.
What gives?

I did the following and got it working again....unfortunately, I'm not sure which action specifically fixed the problem, because I did a few at the same time.
From Google Support:
"Alternatively, you may enable HTML 5 audio without the need for flash by clicking on the gear icon in the upper right corner and selecting 'Music Labs'. From here, you may click the radial 'Enabled' button to the right of the HTML 5 description.(Note: You must be using Chrome, Safari 3.1+ or IE 9+)
Clearing your browser's history and cache has been reported as solving this issue."
Works fine now.
Note: Although Google Play Music is working now, MP3 audio playback directly through the Safari browser still sounds clicky/poppy. This issue doesn't happen when using Firefox.
