(Some) videos not playing in iTunes

I just downloaded and imported 30 new videos into my iTunes library, but when I play them, I only get video and audio in 5 of them--all of the others are only audio, no video. I opened them all in Quicktime and they play just fine, but every time I try them in iTunes, there's still no video. The same thing happened a few nights ago with some similar videos I've had in my library for years, but all I did was close the window once and then they started playing fine; this time, I've tried closing the windows and restarting everything several times and nothing has happened. I am running the latest version of iTunes and Windows 7, if that helps at all.

Ditto. Bought Beady Eye iTunes LP. None of the videos run under Mac OS X 10.6.6.
Fine on iPhone. Nothing doing on desktop. What gives?

Videos not playing in iTunes 7, where can I get previous version of iTunes

Since "upgrading" to iTunes 7, I can't get any of my videos to play in iTunes--they show up but nothing happens when I try to play them. This includes videos I bought via iTunes and DVDs I imported using Handbrake. I didn't upgrade to Quicktime 7 because I was afraid it would cause even more problems for the movies spent hours importing. So I have two questions:
(1) If I get the upgrade to Quicktime 7, will that allow my videos to play?
(2) If not, how can I revert back to the earlier version of iTunes? I have tried searching the forums and have found some information about how to remove iTunes 7, but can't find where to download the previous version (would that be 6.05--I can't remember).
Please help! Thanks.

Never mind. I found iTunes 6.05 in the Downloads section of the Apple page. Now I'm back, thank God.

Purchased videos not playing in iTunes

Hello, recently my purchased TV shows are not playing in iTunes. Video window comes up, and the play time increases, but there is no video or sound.
If I go into "C:\Users\Derek\Music\iTunes\iTunes Music\TV Shows\" and open the m4v file in QuickTime the videos play just fine. (they just refuse to play in iTunes)
Any ideas?
PS: I'm on latest version of both iTunes and QT (just checked).

Any ideas?

ItunesU videos not playing in Itunes but play ok if you download to laptop's drive and run them from windows directory

I'm having a problem playing some ItunesU videos, some play okay, some just show black screen and don't play, others show a still image but then doesn't play when trying to view them from itunes store. The audio files play with no issues.
I am using windows 7.
However, if I download the videos that don't play to the laptop's drive and run them from the windows directory they play okay. I don't want to have to download videos to see if they are something I'd like to watch.
Just for reference, an example of a video that plays okay is by UC Berkeley Math 16A 001, Fall 2011. Another is Introduction to Robotics by MIT.
An example that just shows blank screen is Stanford's Iphone & Ipad development, Fall 2011, both HD and SD versions.
While an example of a video that just shows the initial image but doesn't play is Harvard's Statistics 110. If you adjust the time of the video, the video moves to that part of the video but only shows the image at that time, ex. at 13:02, but doesn't play.
I've tried reinstalling quicktime first, then itunes. I've also tried putting directdraw in safe mode, but the problem videos still won't play.
Could it be some setting, since it plays when the file is downloaded but won't play straight from itunes store online (ie. pressing the play button beside the video in the itunes list).
Help pls.

You might have more luck asking on a general Windows troubleshooting site, but my guess would be an invalid or old audio or CD driver (or firmware in the drive). You might try checking those to make sure you have the correct and most current drivers.

Videos not playing in itunes HELP

So I downgraded my iTunes 11 to 10.6 since I hate the new interface. But I've come with two roadblocks.
1) videos that I've purchased OR i want to preview before purchase will not play. they are just black screens and the timer does not move, there is no audio, no anything. when i re upgrade to 11, everything is fine. but i want my 10.6 back.
2) EVERY TIME i try to play a video, regardless of what video in my iTunes, it prompts me to authorize my computer and I enter my information, but it prompts me every single time, followed by the message that 1 out of the 5 computers you can authorize is authorized.
anyone help : (

Never mind. I found iTunes 6.05 in the Downloads section of the Apple page. Now I'm back, thank God.

Videos not playing in iTunes

I cannot play my videos in iTunes 7.0.1. They are purchased via iTunes on my G5 tower and I used to be able to play them on my MacBook Pro laptop before I uploaded 7.0. I can view the videos and high light them but when I press play, nothing happens. What am I doing wrong? Also, the videos will not upload to my iPod (it says that I am not authorized). I'm assuming that once I can get them to play in iTunes, the iPod problem will be fixed.
Any ideas?

Thanks for the tip. I tried downloading the latest QuickTime and it keeps freezing mid-download (this is not an internet connection issue). I thought updating my OS might help, so I attempted to download the latest OS 10.4.8 and that freezes mid-download as well. Why is it that I can't download anything?

Some videos not playing in Quicktime but WILL play on VLC Player

Hello,
All of a sudden, some of my video files will not play on Quicktime. OT reads the length of the movie but when I click play, all I get is a black screen and no sound even though the progress bar rolls per usual. When I open the videos in my VLC Player, the play just fine. This is not with all of my movies. Some movies play fine in Quicktime. Also, if this helps, Final Cut X will not recognize these movie files for import. Am using Quicktime 10.1.
Thoughts? Help? Anyone?
Thanks,
John

The .dv videos that will NOT play:
I suspect you may have a number of problems here. The first is having elementary DV and PCM audio streams in a DV stream file container. (I.e. DV/DV audio and video stream data is normally stored in the DV file container while DV/PCM data is normally wrapped in the MOV file container.) The second problem is the fact that the DV video seems to be missing the aspect ratio "aware" information. As you can see from the playing file, the format line should read either
720 x 480 (640 x 480)
or
720 x 480 (853 x 480)
Based on this, I am wondering how old this file may be and/or how it was captured. (I.e., the playback problem may be due to file container not being compatible with the QT X player which, in fact, relies on an embedded aspect ratio parameter rather than the QT 7 embedded "Current Size" setting and is not expecting PCM audio to be contained in a DV stream file container.
These videos are older (almost 10 years old) and they were edited in iMovie HD.
In addition, there is a question (at least for me) as to whether the DV video streams are embedded sequentially or as alternative video tracks. (I.e., if you have QT 7 Pro installed, please post a copy of the "Properties" window.
Installed QT 7 and videos play fine. No issues. I don't have QT7 Pro.
Not sure if this will work, but if I had a copy of the non-playing file, the first thing I would try would be to open the file in MPEG Streamclip and re-save the data to a "real" MOV file container to see if it would then be playback compatible with the QT X player app.
Tried Streamclip and it will save as MOV but the size changes (from 640x480 to 720x480 and I get a stretched look. OT X will play it however. Tried to "export" using differrent formats but with mixed results. Sometimes I got sound but no video. I will continue to fiddle with settings but it doesn't seem like a reliable path to go down.
Could I be missing the codec component? Is there a way to check?
Not very likely if any files play have the same video compression format. Had the non-playing files been encoded with one of the HD DV codecs, then yes, that might have been a possibility whould could have been checked.
Would your answer be the same now that we know QT7 plays the videos without any issues?
Exported out to a .dv file. Format exact same as the working one above. Plays fine.
Of course. You exported the audio and video as a DV compressed data in DV stream file container. Thus, both the file format and compression format are now QT X compatible.
The container is a .dv. I did rename it to .mov at one point to see if that helped but got the same result.
Of course. Changing the file extension is like calling a cup of coffee a glass of coffee—i.e., the coffee is still in a cup. Basically, this only works if the data in the container is already compatible with the file container and the container is compatible with the player. For instance, H.264/AAC compressed data will play in either QT 7 or QT X players whether it is in an MOV, MP4, or M4V file container. On the other hand, "muxed" MPEG-2/AC3 data won't play in the QT X v10.2 player with a VOB file extension but will play if you change the extension to TS or MPG. On the other hand, the VOB or MPG file (with the QT MPEG-2 playback codec component installed) will play in both QT 7 (without audio) and MPEG Streamclip while the TS file won't open in the QT 7 player but plays fine with audio in MPEG Streamclip.
I THINK I understand! : )
I do have a DropBox folder.
If you also have an online DropBox account, then yes, that would be a good method for posting large files. You then only have to post or email the URL to the people you want to have access to the data.
True. One of the issues is that I want to re-edit some of these files which means I need to get them into FCP. I know there is a workaround, i.e. importing them into iMovie like I did and then spitting them out again so they will play but I feel like I am losing quality that way. Aren't I? This was before I started saving projects so I could always go back into them. Plus, I really want to preserve the original files for backup sake.
Jon, thanks again for taking your time with me. Really apprecite it.

Videos not playing in itunes. Causes crash.

I own an 8gb ipod touch. Recently, whenever I tried to play my tv shows (that weere bought in itunes) it would crash and say this movie can not be played. I went into itunes, and played a tv show. There was a green screen and itunes stopped working. I already looked into disabling directx and stuff, yet it still happens. By the way, I use windows vista.

Certain music videos will not play in iTunes. The music plays fine but not the video. No picture.

Certain music videos will not play in iTunes. The music plays fine but not the video. No picture. Same with the iPod. Other videos in the library play fine. Help.

Regular playlists vs smart playlist does not make a difference. What I noticed is that some videos create this behavior and some not. I created 2 videos and 2 music playlists, one with 2 songs and 2 videos (that I encoded myself with Handbrake). Another list with 2 videos and 2 songs, videos encoded with Handbrake, but that I noticed they triggered the behavior. The first playlist played fine, with no problems. The second one, created the problem. When I look at the video, it is the same type of video (bit rate, audio channels, etc...) I don't see why it would do that.
Later I will test: playing those videos in question and then selecting songs to see if they play.

ITunes has recently began corrupting my music library and my Podcasts. An exclamation mark has appeared at the beginning of a random number of songs and against some Podcasts with the result that they will not play on iTunes. Message is that iTunes cannot

iTunes has recently began corrupting my Music and some of the Podcasts. An exclamation mark appears at a random selection of songs - about a thoussanad of them - and they will not play as iTunes says that it cannot locate the file. This also has happened on a number of Podcasts. Any one else encountered this?

This happens if the file is no longer where iTunes expects to find it. Possible causes are that you or some third party tool has moved, renamed or deleted the file, or that the drive it lives on has had a change of drive letter. It is also possible that iTunes has changed from expecting the files to be in the pre-iTunes 9 layout to post-iTunes 9 layout,or vice-versa, and so is looking in slightly the wrong place.
Select a track with an exclamation mark, use Ctrl-I to get info, then cancel when asked to try to locate the track. Look on the summary tab for the location that iTunes thinks the file should be. Now take a look around your hard drive(s). Hopefully you can locate the track in question. If a section of your library has simply been moved, or a drive letter has changed, it should be possible to reverse the actions.
Alternatively, if you are running Windows (you've posted in iTunes for Windows, but your sig mentions Mac OS X...), and as long as you can find a location holding the missing files, then you should be able to use my FindTracks script to reconnect them to iTunes.

My ipad2 will not play my iTunes video that i just purchased; i've deleted and reloaded, but they still won't play, only the music

My ipad2 will not play my itunes videos that i just purchased; I've deleted and reloaded them twice, but still won't play; plays music only, any suggestions?

You are playing them in the Videos app correct? Music Videos will play the video in the videos app, not in the Music app.

Hi Crazy Dan:
It's a kind of bug in DVDSP Simulator. If you build your project in your hard drive and test it with DVD Player all video will play fine.
I would like to tell you where exactly the problem is located, but it's just a Simulator problem.
Try building your project.
Hope that helps !

Copied itunes library from one ext HD to another - some music not playing

Hello,
I copied all my itunes library from one external hard drive to another. I backed everything up first then reimported into itunes. About 100 of my MP3 files are in Windows Explorer and the files appear Ok but they are not adding to itunes. The songs is listed in my library as if its there in my playlists but I click on it and nothing happens in tunes. The song won't play if any format from what I've tried. I have researched on itunes and looked on the boards here and I think it is something to do with the encoding of the files, as when I click on 'get info' for the song everything comes up the same as the songs that are working only there is no profile/channel/encoding on the first summary screen. I have tried to import again from my windows folder after changing the encoding 'Import Settings' but it does not work. I also get that (-50)Error when I try and change the settings on the file. Any help is much appreciated.
Thanks,
GH

It's probably corrupted mp3 headers.

Why do some podcasts not play on my touch?

I download podcasts with Itunes. When I sync to my 1st Gen Ipod Touch most play fine, but some will not play on the touch. I get a message that there are some podcasts that will not play on my touch. They are all downloaded with Itunes and in the MP4 format. There are other shows in the same "sieres" that play just fine. But some episodes don't sync. They play OK in Itunes. How do I get them to sync to my touch?

Hi AC,
Thanks for that.
I have Apple TV 1 & only use Handbrake.
An example of 2 problem videos:
High Society
MPEG_4 (Base Media / Version 2): 1.09GiB
1 Video stream: AVC
1 Audio stream: AAC
Encoded date: UTC
Tagged Date: UTC
Writing Application: Handbrake 0.9.5 2011010300
Video 1290kps, 720*416 (16:9), at 25 fps, AVC ([email protected]) (CABAC / 4 Ref Frames)
The Marine
MPEG_4 (Base Media / Version 2): 1.53GiB
1 Video stream: AVC
1 Audio stream: AAC
Encoded date: UTC 2011-11-29
Tagged Date: UTC 2011-11-29
Writing Application: Handbrake 0.9.5 2011010300
Video 2222kps, 1280*688 (1:860), at 23.976 fps, AVC ([email protected]) (CABAC / 4 Ref Frames)
To a layman like me, these specs look similair to specs of my non-problem videos.
e.g.
The Pawnbroker
MPEG_4 (Base Media / Version 2): 764 MiB
1 Video stream: AVC
1 Audio stream: AAC
Encoded date: UTC
Tagged Date: UTC
Writing Application: Handbrake 0.9.5 2011010300
Video 794kps, 512*384 (4:3), at 23.976 fps, AVC ([email protected]) (CABAC / 2 Ref Frames)

Embedded MP4 videos not playing in iOS Safari

Hi everyone,
I'm having a problem with embedded MP4 videos (e.g. YouTube videos) not playing correctly in Safari. When I try to play one, I get one of two problems:
1. On my (first gen) iPad, Safari usually crashes.
2. On my iPhone 4, videos will load but only play audio, not video, though when I tap on the screen the "play" and "pause" symbols appear.
Has anyone else run into this problem? Or know how to fix it?
Thanks,
Mike

Ok, I fixed it. Go to some embedded Flash video, click to run and then right click to get Global Settings for Flash. Go into Storage and make sure you aren't blocking any data from being stored on your computer. At the very least choose the "ask me" setting. (For good measure I also went into Advanced and clicked to Delete All Data associated with Flash. But when I restored Block for data storage the videos stopped working, so that seems to be the answer.) I'd be interested to hear if this works for others.
