Mp4 audio treated as video in 10

Hi
I unfortunately have some audio files in mp4 format, I have noticed that in itunes 10 they are treated as videos and the video screen pops up and instead of being able to navigate through itunes when the track is playing, I am forced to stare at a black screen with the video controls at the bottom.
Does anybody know of a simple way around this, or will I have to fish through my collection and convert them?
Thanks

First, go into Get Info and change the Media Kind on the Options tab to tell iTunes that this is a video. Next, you need to sync this item from the Video tab on your iPod detail in iTunes (i.e. don't sync it as if it was a Music item). If you sync all video content then this will happen automatically once you change the Media Kind. But if you only sync part of your video library, make sure you include this video in the sync selection.
If you still have problems, you may need to convert the video for iPod playback, even if it plays fine in iTunes. If that's the case, right-click on the video and you'll see an option to convert for iPod use, which will make a copy (so make sure you know which version to sync to the iPod, or simply delete the original).

How to play mp4 audio files as video on my iPod Touch?

I know you are all thinking that this is a stupid question based on the topic, but I have videos for some reason that are in the form of mp4 audio, but they are video when I play them on my computer. I can open these videos (mp4 audio instead of mp4 video) using Windows Media Player and it's not just audio, there is also video. However, whenever I try to sync it to my iPod, it shows up in my music section instead of videos. If i play the video under music, all I see is the white iTunes background, no video. Is there anyway for me to set these files to be recognized as video and store it under my movies category?
Thanks.

Mp4 audio but no video

Just installed the newest version of QuickTime and now my Camtasia produced mp4s will not play the video. Is there a fix?

Do you get that if you view any videos on the PC? (Including the QuickTime sample movie down in your program files?
Here's a screenshot of where to find the file on a 64-bit system:
(On a 32-bit system, the \QuickTime\ folder is in \Program Files\ rather than \Program files (x86)\)

Playing mp4 audio gives error message "Video can't be played because the file is corrupt"

Playing a particular mp4 audio file directly from a website link gives error message "Video can't be played because the file is corrupt". However other mp4 audio files from this same website do work correctly. What can I do to get all the the mp4 audio files to play directly from the same website? I must have the correct plugins, etc. since the other files play. This file is not playing from YouTube, is it on the website.
Thank you for your help.

What is the link to the site and file in question?
MP4 files should be handled by Firefox itself, not a plug-in.
# Click the ≡ Menu Button and choose Add-ons.
# Click Plugins.
# Set every plug-in to "Never Activate".
# Try loading the file again. Is there any difference?

Windows media won't play mp4, audio no video

I upgraded from a desktop to the HP TouchSmart 15 TS Notebook PC so that I would have all the functionality
of a new operating system that would work. Guess I was mistaken?!?!?! I have the same problem I had with my old crappy desk-top, MP4 videos still don't play on Windows 8.1???? I get audio but no video????? just a black screen?????

According to Microsoft support website, Windows Media Player still won't support MP4 files. Though we can make WMP play MP4 video by install some codec, sometime we still encounter can't play MP4 in Windows Media Player issue. MP4 is a container format which may contain multiple video and audio streams. And the video and audio stream can be encoded any of several ways. If the MP4 video or audio codec is not WMP installed codec supported one, Windows Media Player won't play MP4 video of this kind. In order to solve "Windows Media Player won't play MP4 files even when the appropriate codec is installed" and to successfully play any MP4 video in Windows Media Player, we had better convert MP4 to Windows Media Player more supported video format like WMV, AVI.

MP4 files have audio but not video

Using Premiere Pro CS6, I have no video when importing clips shoot with the new Canon HF G30. The clips are shoot in 1080P @ PF25 (25P). The audio is fine, but there simply is no video. Importing AVCHD clip from the same camera has no problems. Any suggestions as to how I get these clips imported with both video and sound?

Here they are:

And the AVCHD:
Remember, I have tried importing both clips in Premiere Pro CS6, and the MP4 clip shows no video. The AVCHD clip does.

hi

www.google.com would be a good place to start.

Stereo Audio Treated Separately, How Do I Link?

I recently migrated from FCE to FCP. I love FCP, but there's one difference that's bugging me. In FCE, when you selected and manipulated a stereo audio track, each channel was linked, so when you changed the db level or applied a pen point to one track, the same would be done to the other. In FCP each audio channel is treated separately, so I'd have to repeat the same process for both channels. Is there an option or hotkey to make each audio channel linked like in FCE?

You can also use command/apple L to link/unlink the stereo pairs or individual audio tracks to video.

H.264-Audio but no video

I recently updated my Quicktime Pro with the new H.264 update, but when I watch a movie, I get audio but no video. Any ideas?

It may be MP4 but what codecs? Use get info while playing report back what it says for audio and video codecs. MP4 can be h.264, DivX, 3ivX, XVid, MS non conforming own version and on it goes.....

I inserted a HTML5 video in page, when I test it in a Browser, I see the poster image and controls, But when I click play button the video goes white, slider moves like its playing, but just white picture. There was no audio included in video. Please help

Without a link, it's anybody's guess.
It could be a problem the video rendering itself. Which software did you use?
Did you export to the 3 file types -- MP4, OGG and WEBM to support all browsers?
Does your web server support those 3 MIME file types?

Exporting video for iPod - audio OK but video is "white"

I know this issue has been raised before but I cannot find a clear resolution anywhere - happy to be pointed to the right place.
Some time ago I converted some old VHS home movies to DVD and they play fine. To view them via AppleTV I've converted them to MP4 using H.264/AAC via MEGUI, and they work fine in iTunes on the PC and on AppleTV.
Once they were in iTunes I tried converting them for iPod but the output is a blank white video screen though the audio is fine.
To diagnose the problem I tried loading the MP4 version directly into Quicktime (Version 7.6.8)where the play fine. Then I tried exporting them for iPod and I get the same white screen plus audio.
I've seen this issue dismissed as due to some form of DRM but I doubt that is the case here. The video is my own, the DVDs I created are not CSS protected and the MP4s are also unprotected.
I've also seen it attributed to a missing codec, but that is unlikely given both iTunes and Quicktime play the videos without a hitch.
Any clues on how to proceed?
John

Last post before I leave things alone for a while.
I've uninstalled and reinstalled iTunes and Quicktime and iTunes no longer chews up lots of CPU when trying to convert one particular Quicktime created file.
I've also recreated each file again from the same source, the AVI encoded as DV-PAL with screen res of 720x576. I created a series of test cases to try to pin the problem down and I think the best exposition is the following -
The problem
An MPEG4 file exported from Quicktime loads and plays in iTunes, plays on AppleTV and can be converted for iPod.
An almost identical MPEG4 file created by MEGUI using the x264 encoder, latest build 1649, and all the same settings as Quicktime loads and plays in iTunes, plays on AppleTV but when converted for iPod produces a file with audio but the video is "white". Looking at the file size, less than 2mb, it is pretty obvious that the video stream is simply not there.
Clues
Quicktime Movie Inspector reports the screen resolution of the file it exported as 720x540 while for the MEGUI created file it reports a very odd 787x576. Note that Windows Media Player and YAMB (MP4Box utility) both report this same file as 720x576 which is what I would expect as MEGUI did not resize the video. As an aside, WMP and YAMB also report the Quicktime created file as 720x540 so they agree with Quicktime on that score at least.
Obvious Question
Why does Quicktime report an incorrect screen resolution, and is this contributing to the conversion problem in iTunes?
My understanding is that MPEG4 uses 16x16 macroblocks and so the dimensions of anything to be encoded must be in multiples of 16 and 787 is not a multiple of 16.
Of course, the 787x576 screen resolution could be a red herring.
Details from Quicktime Movie Inspector follow:

Audio (and some video) dropping out export

I've created an project with short video/audio clips sampled to produce "music". It plays OK in FCPX, but when I export it (H.264, 720p, Apple Devices, 44.1) as an MP4, some of the audio (and some video) drops out. That is, it does not show up in the exported (aka "Shared") movie file.
There are about 7-8 things (tracks) going on at once, maximum.
Any ideas what to do to fix this?
Thanks!

Audio, but no video when compressing FCPX files

I am trying to compress a 4-minute video for use on YouTube. I send the edited video from FCPX to Compressor 4 and have used several of the preset settings (H.264 for Video Podcasting and HD 720p Video Sharing). In both cases, the .mov file has audio, but no video. When I use the Export Media option to export the raw .mov file, there is video and audio. Any idea why this is happening? What are the best settings to use for YouTube? When I send it straight to YouTube via FCPX (by logging into my YouTube account), everything works fine. But I need a separate .mov file to send around elsewhere. Any advice would be greatly appreciated. Thanks!

I'm guessing Warwick is correct.
One other thought: if you have an "Export Media" option, your version of FCPX is not current and should be updated. Afterwards, Id suggest running repair permissions in Disk Utility.

My experience is the 720p YT and Vimeo presets are fine for uploading. If your project is 1080p, you'll have that option as well.
By send around elsewhere, the usual tradeoffs between quality and file size apply. Usually h.264 – either Quick Time or MP4 at the original resolution and frame rate – provides the best tradeoff. That is, unless someone is going to be showing it in a movie theater.
Good luck.

No Audio on Air Video

Something odd here - iPad2 - no audio on Air Video yet ok with headphones! All other audi fine including videos on the iPad.
Any suggestions?
Thanks

Make sure your hardware audio button is set to on.
Not all apps check for that switch but airvideo does.
Conversion makes the server convert the selected movie to mp4. Handy to drop in iTunes and sync to your iPad. It converts the movie in the folder where the original one is, or in a folder to be set in the preferences of the server. Click on the icon in the topbar of your Mac desktop to see the options the air video server has.

Nero MP4 audio problem

I have a number of MP4 audio files created using Nero 6. With the recent upgrade of iTunes, the program now interprets them as video. The screen turns black and the sound quality is extremely bad. Besides converting the format, is there a way to coax iTunes to play them as pure audio like the older version did. I have a new x-fi soundcard but I don't think this is the problem because they play fine in other audio applications.
Hope someone here can help, and thanks in advance for any advice offered.

Rename 'em to M4A files. This usually works.
Failing that, load the files up in foobar and use the "Optimize MP4/M4A" function on them. This sometimes helps.
