MKV to MP4 conversion audio out of sync on xbox 360

Trying to convert MKV to MP4 for xbox 360 playback. The passthrough method is a very fast conversion but the resulting file doesn't always playback correctly on xbox 360. The audio is either out of sync or the file doesn't even play at all. Please update this so it works Apple! It's almost 2010! HD is standard!

Matroska (MKV files) does not support the Apple platform.
The xbox is not an Apple product.
I would suggest that you raise your concerns with Microsoft.

G510 Dolby Digital Plus Advanced Audio doesnt work driver problem with Windows 8.1

Hi,
my Lenovo G510 has Windows 8.1 64-bit.
In the system menue of Hardware and Sound I can see two entries:
1) Dolby Digital Plus Advanced Audio
2) Dolby Digital Plus Advanced Audio (32-bit)
Clicking on the first entry a control panel appears. Does this mean that Dolby Digital Plus Advanced Audio is always running in the backround? There is no entry in the systray.
Clicking on the second entry this error message appears:
Your current installed version is 7.3.2.2 of the Dolby Digital Plus audio driver. The software needs the driver version 7.5.1.1. Installe a correct combination of driver and software.
What to do with this? I searched for a solution and drivers but couldn´t find anything.
Thanks for your help.
Solved!

Video choppy after adding audio

This is my fourth year creating a basketball highlight video for the local high school and I have a new problem I haven't been able to solve. I've imported clips from the past 5 games using iMovie HD and everything worked great. I recently added a song for background music (same thing I've done previous years) and now when I play the video it is real choppy. The audio plays fine.
I've seen previous posts regarding this topic suggesting exporting the video with sound track and re-importing. I can't do this because I'll have to go back later to shorten or lengthen clips depending on how the rest of the season goes. I also read you can solve it going back a version in QuickTime, but I can't do that with 10.4. I have playback set to Standard under preferences. I'm using an external firewire drive with 30gb available. iMovie is stored on my internal drive. I've ran all the recommended maintenance on my mac. Does anyone have other suggestions?

Same problem here. Do you have a lot of audio clips? I'm working on a project with around 40 audio clips, and I find that if I delete half of them (no matter which half), the choppy video is gone. Very frustrating, and I hope there's an answer soon which doesn't require buying a new computer.

I am not able to download mp4 files (video and audio) to iTunes since I updated to iTunes 11. Thanks for your help.

Thank you for clarifying. Your question is in your browser, not in iTunes. Each download link is different, and it has nothing to do with the File menu. You can save media files by secondary-clicking on the link to the media file and selecting Save File to "[your downloads folder".

AME - Converting to MP4 and different FPS - audio goes out of sync

As described in the title.
I'm reencoding a 1920x1080 29,97 fps video into a 1280x720 60 fps video. Audio is AAC 44100 stereo.
Basicly a task that many of those free converters on Windows do smoothly. I use Mac...
I'm surprised that it goes out of sync, like 3-4 secs EARLY sound on a span of 2 mins video.
Settings here:
AME CS6 Fully updated
source: 1920x1080 29,97fps MP4 with AAC 44100hz audio
Target:
Codec: H264
Saves as : MP4
1280 x 720
60 fps Progressive - NTSC
CBR VBR1 VBR2 doesn't matter
Max rendering quality
Codec Audio AAC 44100hz (as source)
Any ideas ?

Because we stream at 60 fps and we have to convert all the materials we receive from our partners from the usual 29,97 to 60.
Thanks for your MVPaluable help.

Whatever I export , the final video is always choppy, especially the audio, Why is this? thanks!

I have Macbook pro 15, 2011 , Core i7 ...
When I edit everything seems fine, but when I export the video is choppy and the audio is a mess.. . I don't know why.. I tried exporting in many formats, but same problem

Hi , thanks for your help
The thing is ...whatever I edit ..whenever I export I always get 'choppy' audio . For example I have a video I exported from Adobe Premier... it plays well.... it's audio is 44.1 Kz ... I import it in a project in Final Cut which is also 44.1 and export using same settings and still I have the same problem. I have tried doing it in 48Kz as you said but still... everything I do on Final Cut plays well in the programme but when exported the audio is a mess..
I'm sure it's somehting I'm doing ..I'm not really familar with this ..It's my first Mac and my first FinalCut experience

Choppy Flash video/audio in fullscreen. Fix!

I've been banging my head against the wall for 24 hours now and this works for me.
I have an old MacBook Pro, 10.6.8, newest version of Chrome, Safari and Firefox, and a new Focusrite USB audio interface (Scarlett 2i2).
Installed the newest Flash player (11 something) and the Focusrite yesterday and everything went bad. Choppy fullscreen video, no audio in Chrome etc etc. So anyway, now it's all fine:
MAC/FLASH: Choppy video, no audio FIX.
1. UNINSTALL FLASH PLAYER. It *****. And it gobbles CPU power.
2. Bin the whole Macromedia folder from ~/Library/Preferences.
3. USE CHROME FOR FLASH SITES (has built in flash player - close Chrome when not in use to shut its flash player, to save CPU power).
4. ALSO: Have a USB audio interface? AUDIO MIDI SETUP: 44.1kHz OUTPUT.
That's it. Everything is now smooth in fullscreen in Chrome, and great audio through the Focusrite box.
*fingers crossed*

Does removing flash have any affect on the other browsers?
Yes - flash videos will not play in other browsers. Chrome has built-in flash so it still works.
However some YouTube videos will (after 2 seconds or so) detect that you don't have flash and default to H264 playback which seems to work fine.
I've now been using Chrome only for flash palyback for a couple of weeks and it works fine if you follow the steps above.
Last point - I often have to set Youtube to something lower than HD playback. Maybe just an internet speed thing.

Imovie exported to mp4 choppy audio on PC QuickTime player

When I created a mp4 file from imovie, my client with a PC who has a QuickTime player hears choppy audio. It won't even open in his Windows Media Player bc of Codec issues. Then QuickTime plays it but audio is all choppy. It plays fine on my Apple. What am I doing wrong? If I create a QuickTime file, which I'm doing now, is there a special audio setting I should change so this will work on a PC?
Thanks!

When you export out of iMovie are you doing it using Share> Export QuickTime file or Export Movie? Believe it or not, you can export to Movie and rename the file extension from .m4v to .mp4 and get that to play on any Windows machine with Windows Media Player installed. It maybe a simple matter of saving it out to Movie, renaming it and sending that one along to the client, see if that one works better.

IPad Won't Sync with MKV to MP4 720p Videos

I converted some mkv files (1280x720p x264, AC3) to mp4 using QuickTime 7 and Perian by exporting to mp4 with the video set to pass thru, and the audio set to AAC 160 Kbps 48 kHz. ITunes won't let them sync with my iPad, but it doesn't tell me why. One possible issue is that the atom (something I know nothing about) has been reported as having a length larger than the whole file by another program. Is there something I can change with my conversion method or an application on the Mac that will repair the atom?
Thank you

Are you actually trying to determine the cause of the problem or just end up with a playable file? If the latter, then don't pass through the video unless you are certain it meets the Main Profile @ L3.1 (or under) standard. Otherwise, re-compress both video and audio to supported standards as specified on the Apple web site or use any compatible QT or third-party preset you may prefer.
If trying to determine the actual problem here, then download and use one of the various movie info utilities that will allow you to examine the various settings used to encode the source video track to specifically include the profile and level used and see if they comply with ISO/IEC Moving Picture Experts Group standards. Many non-Apple custom encoded source files may either be encoded using profiles/levels exceeding iPad limits, employ hybridized or mixed encodings features drawn from multiple profiles/levels, or simply require a third-party decoder like those included in the Perian component package for playback and which, of course, are not available in the iPad firmware OS. Basically, when you pass the video data through without confirming its compatibility, you do so at your own risk.

Convert MKV to MP4 or WMV with PrE

I would like to convert a .MKV video file into a .WMV or .MP4, since the video cannot be read by standard hardware as it is.
I tried to open it with Premiere Elements, but it couldn't be read by PrE, so I cannot export as a different format. Is there any work around to this?

DeverK
Thanks for the follow up.
From the looks of it, you can convert to MKV (if you wanted that file extension) or MP4 with the free HandBrake.
I have used HandBrake (Windows) for conversion to H.264.mp4 with constant frame rate, when the counterpart with variable frame rate
would not work in Premiere Elements or when it imported but with audio out of sync.
It appears that with the choice of MP4 as the container format (file extension), the choice of video codec is described
H.264 (x264)
MPEG-4 (FF mpeg)
MPEG-2 (FF mpeg)
whereas, with the choice of MKV as the container format (file extension), the choice of video codec is described
H.264 (x264)
MPEG-4 (FF mpeg)
MPEG-2 (FF mpeg)
VP3 (theora)

OfficeJet Pro 8600 Plus Make Audio Sounds In the Early AM Hours Recently

My Office Jet Pro 8600 Plus has been making audio sounds usually around 4:30 am lately , but has also done it sometime after midnight also. The sounds will activate somewhere between 2 or 3 times every few minutes to 2 or 3 times in a minute. This will continue for about a half hour. It's been doing it for several weeks now. This is when the printer is not being used, and is a low power state. When I'm trying to sleep. During this time the display screen does not come on and remains dark. Once I got up from bed and touched the screen to activate it to see if there was some kind of message, there was not.
What's causing this to happen and what can I do to stop it. I've had this printer for 2 1/2 years now, and this is a fairly recently problem.

Hi @darrel112
I realize this may be a strange question, no more strange than the sound you are hearing I suppose, I was wondering if you could describe the audio sound for me?
Knowing the type of sound that is occurring may help me to identify the cause. While I wait to hear from you, something to consider is the printers power source, is the printer connected to a wall outlet or a surge protector/ power bar?
