Clock out of sync when roaming

I went abroad for a few weeks and the clock never synced with network time. Because of that, the time was never correct and could gain upto 2 minutes each time I rebooted. I have an O2 Pre at version 1.4.1.

Hello and welcome to the forums;
When roaming, you can turn off network time and if you run into a situation where your time is off, you can then manually set it.
There is also a homebrew app that can sync your device to internet time (much the same way most PCs update time) however as this is homebrew, we are unable to offer additional support for installation or how to use it. www.precentral.net will have all the information you need, and a great support community that can help with installation and troubleshooting if you choose that route.
Hope this helps,

Audio out of sync when playing HD content

Hey
I've got an issue with the audio gets out of sync when playing some HD content. I've tried to make sure the video is stored on the Apple TV so it can't be the network connection.
I've also tried a full reset of the unit, but still no luck.
But it's all video clips that has this problem. Even though they encoded the same and so on, some videos audio get out of synced and some don't.
Also have a problem with m4v files locking the ATV (and iTunes for that matter), but renaming it to a mp4 file seems to solve it. But if someone has a fix for that as well I'd much appreciate it.
Many thanks in advance,
Jeaz
EDIT: I have tried to use component cables instead of HDMI, but the problem remains. Of course also tested the video on my Mac and no problems. A quick pause and resume usually solves it, but only for a minute or so.

What sort of specification is the video content? Is spec too high for AppleTV.
It may be that it's some kind of bug in AppleTV's playback, that the Mac does not exhibit, or an issue with encoding that causes a problem only on AppleTV.
If you are encoding video and using same as source for the frame rate, it may be better in some cases trying explicitly to specify the frame rate required in case automatic frame rate conversion is introducing some kind of timing issue. Test a short clip to see.

Out of Sync when importing rendered sequence

This is the first time I've had this happen and haven't been able to solve the problem yet and haven't found any solutions yet through searching. Using CS5.5, I'm building a show consisting of 7 or 8 already rendered sequences. All seem fine when put together, but one sequence is thrown way out of sync when I import it. The file plays fine otherwise and it isn't until it's imported into premiere that the problem occurs. I've tried re-rendering several times and get the same out of sync problems. And it eventually gets wildly out of sync, not just a few seconds. The properties of the clip are:
Type: MPEG Movie
File Size: 1.5 GB
Image Size: 1920 x 820
Frame Rate: 23.976
Source Audio Format: 48000 Hz - compressed - Stereo
Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
Total Duration: 00:04:23:09
Average Data Rate: 6.0 MB / second
Pixel Aspect Ratio: 1.0
This is the same as all the other rendered/imported sequences. I'm at a loss here. Is there anyone who can help steer me to solving this?

Welcome to the forum.
Just so that everyone is on the same page, when you say "rendered," is it safe to assume that you mean that that file was Exported, and then is being Imported into a new Project?
Good luck,
Hunt

A portion of audio that is synced in iMovie, is out of sync when burned with iDVD. How can I avoid this?

I'm trying to burn a simple movie, using iMovie and finishing in iDVD. A portion of the audio is out of sync when burned, despite it being in sync in iMovie. Any suggestions?
Thanks.

Hi
Try to - Save as a DiskImage - then test this with Apple DVD-tool.
Does this play OK - burn this DiskImage by using Disk Util tool.
Set down burn speed to x2 or 4

IMac clock out of sync

So, since updating to Mavericks, I've noticed 2 issues.
First is the clock goes out of sync by about 5 minutes each day. I'm comparing it with my iPhone 5 and I know it's right as the iMac drops back to the correct time when I update from Date & Time in System Preferences.
Second is an issue with the switch user cube thing. I don't have Guest User on and it does this weird thing where it'll rotate the Desktop when updating things like AirPort Extreme settings from AirPort Utility and just now I updated VLC and it did the same thing. When it did it with AirPort Utlity the first time, it didn't switch back and I had to lock the screen and wake it up for it to display the Desktop again. Just showed a blank, white screen with nothing on it but the mouse cursor...
I have reset my PRAM yet for the clock issue but I believe it's software related as I've not had any issues prior to installing Mavericks.
Everything else seems to be okay other than some icons on the Desktop not showing previews for images or videos.
Anyone else experienced something similar? I know there's an update due shortly so hopefully that'll fix the problems...

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Video + audio recorded in Quicktime X is out of sync when used in iMovie

I have recorded video in Quicktime X. When I try to edit it in iMovie, the audio and video are out of sync. They are in sync if I play the video in Quicktime. I am using the latest version of iMovie '11. Anyone know how I can fix this?

You should not HAVE TO but did you try extracting out the audio? This has been a issue for a long time. I am not sure why you never see this problem in Final Cut but it rears its ugly head in iMovie all the time. What do the call it now? Oh yes... detach. Select the clip then Clip -> Detach audio and line it back up.

Audio and video out of sync when using quicktime conversion

hello,
i am editing a hdv project and want to export to quicktime. the client needs it in a specific size (700x394). they do not want the video in the file compressed, just the size of image. they are compressing the video through flash for the web. anyways, i used to just use quicktime conversion, custom size and use 700x394, but now when i do that the audio and video are sparadically out of sync in the product. the wierd thing is that the project plays fine in the timeline, but when i export the problem occours. i then, exported to a full res fcp movie and it is fine. then tired reexporting through qt pro to 700x394. when i did this their were no sync issues but the quality of the file was not so good, it look more pixely, certainly not as good as when i did it using quicktime conversion.
how can i export through fcp to get the 700x394 file? someone said 'use current settings' instead of using quicktime conversion? how do i do this? what do i need to do and what are my settings?
any help is appreciated. thanks a ton in advance.
cheers,
clay

What format are you converting the HDV to?
If it's animation, it is quite possible your computer can't pull the data rate. In this case it would be a processor / hard drive issue not an out of sync issue.

Out of sync when converting from QT to DVD???

Using my Kodak Z812IS, I have no problems watching the .MOV files in QT. However, when using DVD Copy 5, from Intervideo, I make a DVD to watch on the TV and the audio is out of sync. Anybody know of a fix for this? If I have to purchase anything to make this work will be no problem. I bought this camera just so that I could make DVD home movies... Thanks for your help, if there is any. ..bob.

Anything here help?

Quicktime file out of sync when trying to convert it to

I was sent a .mov file created on a Mac via yousendit.com, and downloaded to my office PC via yousendit.com. I need to convert it into a format I can burn onto a DVD using Vegas Pro and DVD Architect.
It plays fine as a .mov file from my desktop but when I play it from DVD Architect, the sound and picture are out of sync.
I put it into Vegas Pro to see if I could sync the sound but there is no picture when played from Vegas Pro.
Is this because there is a problem with the .mov file, and/or the fact it was downloaded from yousendit.com, or is it a problem with DVD Architect and/or Vegas Pro?
All help much appreciated.
Thanx.

Hey,
Please mention the configuration of your system specially CPU and RAM.
This error usually occurs, if you run too many memory-extensive applications simultaneously. So try performing those redaction tasks after closing some of the background processes/applications
Hope that helps.

Audio goes out of sync when i open project on diff macs

i have an iMovie project created on an iMac saved to an external.
I go to open the project up on my macbook and the audio is out of sync.
I go back to my iMac with the same project and it works just fine.
I'm a bit confused because both macs use Mac OS X 10.6.4 and iMovie 8.0.6
what other differences might there be?
any input is appreciated as I'd love to work on projects while out in the field!

Try exporting the iMovie project as a single full quality dv format quicktime file.
I use iMovie6 HD and this is my usual procedure that works well.
Make the movie in iMovie, will involve many separate clips. When finished, export (share) as a single full quality dv format quick time file. When I have an hours worth of smaller projects, I create a new iMovie project and import all of the quicktime .dv files for each separate short project. I add chapter markers in this project, then share with iDVD. I then burn an hours worth of stuff at best quality and distribute to family and friends.
iDVD seems to work better with iMovie source that has fewer clips.
BTW: Are you having problems with standard def or hi def iMovie source. Another part of my procedure is that I take the raw tapes and download the entire thing into one iMovie project. I don't edit or change the footage at all, just want to archive to DVD for posterity. In this case, I want to share the iMovie project with iDVD directly. This has worked OK for standard def projects, but my first hi def project (1080i) that I tried, the sound was out of sync. To fix this, I had to create a regular DV widescreen iMovie project, and drag all the clips into it from the HD project. It took over an hour for my humble mac mini to convert the files, but I was then able to share with iDVD and the finished DVD worked ok.
Hope this helps.

Why does my audio slip out of sync when exporting?

I am exporting an HD edited video. I shot 1280x720 & editing in FCP 6.0.5. I am using APPLE PRO RES 422 1280x720 30fps 48kz . Should it be (HQ)?? - I do not select re-compress all frames or make self-contained. I just want a QT reference file to view and then burn a DVD. My clip is 43 minutes long. HOWEVER, the audio drifts out of sync BIG TIME. Why is that??
Here are my sequence settings:
1280x720 Aspect Ratio HDTV 720p (16:9)
Square Pixels
H.264
Audio at 48kHz

That's what I thought, however, when I play back the .mov file after exporting using "current settings", that's when I experience OUT OF SYNC audio. Do I ignore that and drag and drop that file into iDVD and let iDVD crunch it??? Is it just the playback of that .mov file that is out of sync?

Audio is out of sync when placed in the timeline!!!

When I play a clip in the viewer, everything is fine, but when the clip is placed into the timeline and played in the canvas, the audio is out of sync by about half a second. I noticed that even when I view the sound waves, what I hear does not match up with where the playhead is. This is extremely frustrating and I have currently resulted to physically moving the audio to match it up, something that I do not want to do for the duration of my film.
I read in another post that the video and the audio could not be at the same level. How can you tell if the video and audio are at the same level??
I have FCE 3.5 if that makes any difference. Any help would be much appreciated!

How was this clip imported? If it was captured/ingested, did you make sure that the sample rate of the capture settings matched the sample rate of your audio? Normally FCE will give you a warning if they don't match, but it can't hurt to make sure.

Audio goes in and out of sync when burned dvd played on standard DVD player

I made a short film recently (7:00 mins) and once completed and burned to DVD using iDVD and DVD Studio Pro about 20% of the clips have out of sync audio. Just slightly out of sync. Some more noticeable than others.
Playing off the timeline syncs perfect, the exported prores 422 mov file syncs perfectly, and if the finished DVD is played on my mac or my pc the sync is perfect, but when played on a standard dvd player to my TV I get the syncing problem, but only at certain points through the film. As I said, about 20% of it. The rest of the film is fine.
Shot on Canon 5d mkII - footage converted to prores 422 1920x1080. Audio recorded on Zoom H4N with some ADR recorded on logic pro. Audio synced manually using clapper board reference. Using a 27'iMac with current OSX update as of 14 March 2011. Edited in FCP 7, exported to proress 422, burned to DVD with current iDVD and DVD Studio Pro, all current versions and updates.
I have tried exporting to mpg4 and mpg2 - no joy. I checked audio bit rates and discovered the logic recorded stuff was 44.1khz as opposed to 48, so I converted to 48 but still no fix.
I am STUMPPED
Any suggestions?
Cheers

Should I convert just the clips which are out of sync in the DVD, or all of theclips in the FCP timeline?
If that is the issue, wouldn't I have the problem in the final prores mov as opposed to just when its played dvd to tv?
Ill try it though. Its an odd problem so its likely to have an odd solution. Willing to try anything at this point.
Thank you.

Music slightly out of sync when exporting in Premiere CS6, format problem?

Hi guys, i have a quick question.
I edited together a promo for a local band and everything is perfect in the sequence as far as being on point with the music at certain beats and such. However when I export it the music is slightly out of sync, which is bad when you edited everything specificly to the song. I am not using ANY audio from the footage but instead layed a music track over everything. I'm not sure what else to do, could it be a format problem? I am using h.264 (see below), but would AVI or anything else work better? any help is appreciated thank you!
I am exporting directly from inside Premiere CS6 using a custom H.264 preset. 24fps, VBR 2 pass encoding. Target 7MB, Max 11MB. (with render at maxium bit depth, and render at highest quaility selected.)
I put the audio settings to high, 320kbs AAC format.
I use a custom built PC with an i7-3770K, 32 GB RAM, and I exported to a 120GB SSD.
Any other info you need just ask.any types for uploading to vimeo so it doesn't get out of sync there? thank you in advance!
Also, any types for uploading to vimeo so it doesn't get out of sync there? thank you in advance!

Hi,
I dont think that you will really get a problem while exporting in any of the given formats. But i would really like to check if the audio layer is exactly same as of the video. for eg - if my audio is 00:05:30 and my video is 00:05:20 , we might face issue with the sync.
We can try to put more black video to make it a match with the audio and then try to export.
Where do you have the media files , on a internal drive like c: or desktop? In case not , try to move the media files to desktop and then try to export.
Also instead of exporting the files to your 120GB SSD , try to export it on the desktop.
Hope it helps.
Thanks

Rate Stretch audio goes out of sync when exported.

Audio, which is rate stretched using the rate stretch tool to 100.01%, plays fine in Premiere Pro CS6. However, when exported to Encore or to MPEG-2 file, the audio is no longer stretched and becomes out of sync by the end of the video. When I play the preview in Encore, the audio is out of sync. Switch back to Premiere, it is OK. Export a MPEG-2 file and author a DVD, the audio is out of sync. Go back to Premiere, it is OK. I record the audio using a TASCAM portable recorder. I have recorded and synched audio many times and this is the first time that it does not work, on two separate Premiere projects. Any ideas on how to fix this. Even better, is there a way to record audio so that it matches the video (from a Panasonic HD AVCHD camcorder) without requiring rate stretch adjustment?

Try changing the speed with right click, Speed/Duration instead of using the Rate Stretch tool.
