No audio in MP4 file ?

I was export timeline xdcam 35 mbs, 720p 50 fps to MP4 720p 50 fps.
When looking video on Mac everything is ok, but, when I copy MP4 file to USB and put directly to LCD there is only video, no audio? Before on G5 I was use matrox compress card, and always MP4 file was ok on LCD. Where is problem? tnx.

I do not know maybe it's a coincidence. Because I was made before in the AAC audio format​​, so one video has audio on LCD, second NO,  although there is same preset from Compresor. Before with Matrox Compress HD on G5  has never been a problem.
In this MP4 I haven't audio on LCD, AAC,  44.1 khz,
And Why is original height/widht not same like encoded video? I did not touch the video settings, such Crop

  • Incompatible audio from MP4 file

    I have several business partners that are supplying me with .mp4 files from Adobe live flash media encoder, using the h.264 codec, but the only audio choice is for an MP3  codec. this combination displays/plays no audio in Premiere Pro CS5. Only after I use handbrake to convert the audio to the  AAC codec with it play in the Timeline.The upgrade to the main concept plug-in for AFMLE will allow for this, but the business partners are reluctant to spend the $
    Question: is CS6 compatible with the default of FMLE with h.264 and the .mp3 audio? if so I will upgrade.
    anyone else see this issue when using .MP4 files?

    You can always install the trial and see for yourself.

  • Audio in .mp4 file cuts off

    The audio in the mp4 file I am trying to use gets cut off. It plays 95% of it, but for some reason cuts the audio off towards the end. I have checked the file on both a PC and Mac and on both the audio shows fine, but when I open it on my computer (Mac) it is cut off. I have tried a clean install of AE CC 14 and that did not help.

    MP4's and compressed audio may or may not play well with different machines. It's the nature of a format that is CPU intensive and decodes the file in blocks.
    If you start with a frame based source that has a standard uncompressed audio track the changes of having a successful render of your mp4 is much higher, but still not 100% guaranteed.

  • Will iTunes or QuickTime Player let you burn an mp4 file onto an audio CD?

    I want to burn some MP4 videos (i.e., the audio portion only)  onto audio CDs; I guess that would mean converting to .aiff files, right?
    Can this be done in either iTunes 10.6.1 or QuickTime Player 10.0? I'm running Mac OS 10.6.8 on a Mac mini, if that makes any difference.
    Or do I have to find some third party software to do the conversion and then burn the CDs?
    Thanks in advance for any advice you can offer.

    I want to burn some MP4 videos (i.e., the audio portion only)  onto audio CDs; I guess that would mean converting to .aiff files, right?
    Depends on how you plan to play them back. AIFF can be played on almost any commercial audio CD player. MP3 files can be played on most current CD players. Apple Lossless or AAC could be used if playback is through your computer. The choice is really yours.
    Can this be done in either iTunes 10.6.1 or QuickTime Player 10.0? I'm running Mac OS 10.6.8 on a Mac mini, if that makes any difference.
    Yes, but the work flow may be different depending on which software and audio compression format you use. E.G., QT 7 Pro could extract the MP4's AAC audio track directly to an new file without conversion if AAC is your target format. As previously mentioned, QT X could be use to recompress the MP4 to an audio only AAC file. The free MPEG Streamclip or QT 7 Pro apps could be used to convert the MP4's AAC directly AIFF files. Converted or extracted AAC files could be added to your iTunes library where iTunes could create and burn a "Playlist" of such files to CD using AAC, AIFF, Apple Lossless, MP3, or WAV compression formats dependin on your playback requirements. (Unfortunately, iTunes will not directly extract and reprocess/burn the AAC audio directly from MP4 files already in its library.

  • Audio of .mp4 movie files getting distorted by 1 hour mark.

    I converted some of my fave movies from DVD to .mp4 file format that my iPod supports. After I did so, I copied several flicks in .mp4 format to my iPod. Each of those movies is at least 2 hours in length. But the problem with iPods playing .mp4 vids is after 1 hour mark of the video, the audio gets distorted up the rest of the movie. My friend with iPod vid also experienced the same problem. We found out that if the movie is in .m4v format, the audio of the same movie length is smooth and clear. This make me think that iPod videos has bugs playing .mp4 video format that has more than an hour in length. Ironically, when I play .mp4 format in Quick time and iTunes (in my PC), the audio is smooth. Does anyone have an idea about that? I appreciate for the answer. Really. Thanks!

    I think  is the contrary because the clip browser copies all the foleders needed. I got this opinion from another forum that copies into Final Cut:
    "My workflow is to create a hard drive folder for the project, then use Clip Browser to import the clips from the card. I review the clips, labelling them, adding logging notes, setting the status and putting in essence marks as needed (the number of characters available for the essence mark description is fairly limited). I then open FCP, create and save a new project then call up XDCAM Transfer. I select the project folder and it will pull in all the clips. I then filter for OK status, occasionally create subclips then import. The clips come over to the bin, with their names and with the essence marks converted to markers. Obviously there are backups taken - I've not mentioned them."

    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".

  • Premiere Elements 4 audio won't play on mp4 files, codecs missing/unavailable on .mov files

    I dowlnloaded Premiere Elements 4, and when I import mp4 files, the video plays but the audio will not. I've also tried to import .mov files, and an error message pops up that says "Codec missing or unavailable." I downloaded the latest version of Quicktime, but that didn't change anything. The files will play back on the video camera, but I"m having trouble with them on my computer. The audio on the mp4 files plays in Quicktime, but not the video, and vice versa when I import them into Elements. Any suggestions?

    Does Quicktime Pro also edit .mov files on a PC?

    Premiere Elements 4 pretty much works with tape-based digital video. That would be video from a miniDV or HDV tape-based camcorder. It doesn't handle other formats very well.
    If you plan to edit MP4s, you definitely want to upgrade to a more current version of the program. If you can't install a current version of the program, you may need to address issues on your computer (such as an outdated operating system or underpowered hardware configuration).
    Short of that, you could buy Quicktime Pro from Apple for $29. It will edit MP4s, even on a PC platform.

  • Why do the MP4 files that I import to Premiere Pro CC have unsynced audio? (Resolved)

    I have identified and resolved.the issue. There is a bug with how Premeire Pro handles importing videos with variable frame rate.
    Community Memeber Walter.Johnson found a work-around at the bottum of this post, which also has the identification and submission of the bug itself:
    http://forums.adobe.com/thread/1110005?start=40&tstart=0
    I had to convert the video with "constant framerate" selected in handbrake. I'm believe the ffmpeg CLI equivilant switch is "-cfr" but I have not tested to be sure.
    I can now import videos with synced audio!
    I have recorded several hours of footage using a program called XSplit (a screen recording tool).
    The files are recorded in a FLV format and I then convert them to MP4 as premiere pro cant read then in FLV.
    In a MP4 format I can import the files into Premiere Pro CC and the video looks perfect, but the audio is unsynced. It is also unsynced in non-linear way so it is not something that I can simply unlink and adjust to compensate as it would have to be done manually every minute.
    If I import these same MP4s into other video editing programs they import perfectly fine and have no audio sync issues what-so-ever. I only experience this issue in Premeire Pro CC. I can even tested these videos in 6 different media players and they play perfecly fine.
    If I convert the files to AVI using ffmpeg or ffmpeg assisted tools it will not import into Premiere Pro CC and gives a "unsupported format or damaged file" error. Once again, this avi can be played and edited in several other programs no problem.
    Here are the details about one of these files:
    VIdeo Codec: H.264/MPEG-4 AVC
    Video: 1280x720
    Audio Codec: mp4a: MPEG-4 ACC LC
    Audio: 44100hz 63 kb/s tot , stereo (2/0)
    Anyone have any ideas on why the audio is becomming de-synced in Premiere Pro CC only?

    I'm happy to announce to you all that my "mp4 importing" issues has been sorted out. Now I import mp4 shot with the same Windows Phone 8 Device into Adobe Premiere Pro CS4. Only that for the moment, it doesn't play as fast as with ordinary player.
    But how did I get it to work, you may wonder;
    I simply installed Itunes on the system, I also installed an app called media monkey. I can't say which of the apps did the magic but the next time I tried to import mp4 files into Premiere Pro after these installations, it imported seamlessly.
    Obviously there's a link between the required codecs and the itunes itself.
    You may want to try it and hope it works for you.
    Kindly inform us if it works.
    Thank you all.
    Cheers.

  • No audio in previously working imported MP4 files. . .

    I've noticed a new issue with iMovie over the past few months where previously working MP4 files (we use hardware MP4 recording decks to record class videos) now no longer have audio when imported into iMovie.  Also, Quicktime doesn't play these anymore.  I suspect it's a Quicktime issue at its core because that's what iMovie uses to import video files, but the immediate symptom is in iMovie.  We use two different types/brands of recording decks, so it's not an issue with a specific one, and their firmware haven't been changed.  The only thing that has been updated or changed is the Mac.
    The only way I've found to get these videos to play properly is to pass them through Handbrake, but that's a huge waste of time, and I honestly don't think that's an acceptable solution.  Is there somebody with actual knowledge of this problem who knows a fix or whether a fix is in the works at Apple?  Please don't just send me to some outdated "troubleshooting" list that has things like "try restarting imovie."  That's a waste of both of our time.
    Thanks.

  • MP4 File in Adobe After Effects CS4 Only Plays Audio

    So, I recorded some videos of Just Cause 2 on my PS3, and transfered them over to the videos section, I then put the videos on a USB flash drive, and put them on my computer, where I tried to open them in Adobe After Effects CS4, it didn't work. xD
    It pretty much has no video, only audio.
    But if you play the actual file with a player like Windows Media Player, it'll play fine.
    I've tried changing the file extension to Mov, WMV, AVI, and every other one I could think of. And it'll only give me an error saying it's probably not a supported file type xD.
    Oh, and I also have other mp4 files that will open in AE fine.
    Any help would be awesome.

    Transcode the file using tools like SUPER©, MPEGStreamclip, ffmpeg and so on. There are too many flavors of MPEG 4 out there that AE could handle them all and this seems to be exactly one such case.

  • Audio Video does not sync upon INPUT of .mp4 file

    I use Elgato Video Capture to digitize 6-hour VHS tapes. It emits *.mp4 files and passes them to iMovie.
    In iMovie 9 there were no problems.
    Using the same workflow in iMovie 11 leaves the audio lagging progressively behind the video. Amusing, but useless.
    I searched these forums and found answers to the problem of in-sync audio getting out of sync on export. That is not my problem! My audio is out of sync upon import into iMovie 11.
    Do I have to go back to iMovie 9?

    I don't know, but if it were me, I would use EyeTV to export shorter chunks, e.g. logical events, rather than all 6 hours at once.
    Alternatively, you could use MPEG Streamclip and chop it up there into logical events.
    You can right-click on the EyeTV recording in EyeTV and select reveal in finder. Then right-click on the .eyeTV file in the finder and select SHOW PACKAGE CONTENTS. You can then drag the .mpg file into MPEG Streamclip and split it there. You may need the $20 Apple MPEG2 Playback Component. MPEG Streamclip will tell you if this is the case.
    The advantage of doing it in EyeTV is you wouldn't have to spend the $20.
    My only other idea is to check the EyeTV forums.
