Quicktime won't play my movies, just plays audio

I have some movies downloaded that were .avi files when i got them, I used Divx Doctor to convert them to .mov files. Now, they play fine on my iBook G4, but on my new iMac all I can get is the audio. The movie info says the video is 3ivx 4.5.1 and I have the 3ivx codec installed on my iMac but it still won't play. In fact I have all the same codecs on the iMac that I have on my iBook. Any help would be greatly appreciated.

Try playing it on the iMac under Rosetta. Believe 3ivX v4.5.1 is for PPC Macs only.

When I play a movie through iTunes, audio has no issues but video stutters and skips

Hey everyone,
I have a Dell 17R, Windows 8 64 bit, intel i7-3630QM at 2.4 GHZ, 8gb ram, Nvidia GT-650M at 1920x1080 using driver 320.49
When I play a movie in iTunes, the audio works flawlessly but the video will be smooth for a few seconds, stutter and then skip small 2-3 second spots. I haven't noticed that the parts skipped are any more graphically intense than other spots and there is no discernable pattern.
In the past, I have been able to play movies through iTunes with absolutely no problem but when I downloaded this most recent one a few days ago all of my movies have been experiencing the same issue.
When I stream other videos from other sources I do not experience the same problems as I do when I use iTunes. Streaming 1080P over youtube or a similar services is no issue.
I have updated my video drivers to the latest version as well.
I am at a loss, any suggestions would be appreciated.
Thanks!

Audio selection in Cs5.5 Encore auto plays rather then just changes audio track

I am an Encore newbie after moving from DVD SP to Encore for blu ray menu authoring. Ive read and re-read the help files and they seem to be the same for Encore versions going back to at least cs3 for this issue ... so i must be doing something wrong or Encore just cannot do a very basic thing...
I am building a blu-ray with a singel video track and 2 audio tracks. I am trying to link a menu to allow a user to select a 5.1 or 2ch version of audio for a feature film. All shoudl be straightforward. i have a menu with several buttons. Each button links to an audio track in my timeline.
However, when i test my links, instead of just changing the audio and returning to the menu (as per the instructions in the help files ), the film plays from the beginning.
The correct audio track is played, but that is not my intention at that point. I want the user to choose the audio track and then allow the user to press another play button or go to another menu and back again before the film starts.
So how do i just change the audio track but not play it there and then ?
The help says use 'specify link' so i choose that option and select the timeline, yes, select the audio track 1 or 2, yes. But there is no different way to do this if i actually wanted to play the track at that time as well. What is the fundemental bit i am missing here ? Something to do with button type or some werid overide setting i am missing ? Can Encore actually do this ? its rather frustrating having come from using DVD SP which allows you to script everything and set gprm/sprm registers, to a program that does not seem to allow you to do anything beyond very very basic authoring.
Any help would be appreciated. thanks.

To return to menu after changing the audio or any subtitle track, you should select the desired menu in the Specify Link option and change the audio and subtitle accordingly.
In the example above, what I have done is, I went to the Specify Link, chose the menu as the target and also changed the audio track there and clicked OK
So here, after pressing Button 3 (Item 3), I would return to the menu and my aduio would be reset to audio track 2.
After that, whatever timeline I play, that would be played with audio track 2.
That is just a small example to show how it is done. Set the navigation as you like.

Why won't the Apple movie trailers play on my Mac?

Some trailers play the sound, but no video. Some don't do either. This problem exists on my Intel 24inch iMac and my intel Macbook. This problem has existed for weeks if not longer. All other movies, QT or iTunes play just fine. Solution please?

It won't let me download iOS 7. When I check for software updates it says that it is up to date. I also went to iTunes to delete the songs from the iPod, but now it isn't even recognizing any devices. I even uninstalled iTunes and reinstalled it to my computer. LOL I am sure it is something small, but I don't have the patience for it now. Maybe I should step away from the computer and come back in a little bit... Thank you for the advice though! Keep it coming! I know it is hard to diagnose over the internet, but any ideas help!

I am using MTS files. They load in PE fine. The problem is when I try to play them, I just get audio and no video. I have installed the latest updates. Is there a CODEX that I need.

I have windows 8.1. I have downloaded the mts files from my video camera onto my hard drive. I have loaded a subset of these mts files into premier elements and they show up fine. I can bring them to the time line without a problem. The issue is that when I click on them, I only get the audio and no video. Normally when you click a thumbnail, the picture shows in the large screen. That screen remains blank.

John - thanks for your response
1. Graphics Adapter: Nvidia GeForce GTX 650
2. My driver before you response was 3/4/14   9.18.13.3523. I went to Nvidia and downloaded and installed latest driver 7/2/14 9.18.13.4052
3. Rebooted and checked APE and no change in the problem. Still doesn't show video when I double click an thumbnail or if I single click it does not show a video image in the large screen.
4. Some things I have done to try to resolve the problem.
     a. Searched this forum for a similar problem. I didn't see one.
     b. Did a web search to see if I could find a solution outside this forum
     c Went into "edit" and tried some changes in project preferences and setting to see if that would make a difference
     d. Tried to contact Adobe support to speak to a person but that seemed difficult and could never figure out how to do it.
5. I have always loaded AVI clips into this program and this is the first time I have tried MTS files. When I opened the new project, the program notified that I had to change something??? to load an MTS file and asked me if I wanted the program to do this for me. I said yes and here I am.   I seem so close to making it work.   Thanks

Please explain further.
Do you have the HD version on your iPad?
Did you download it directly to your iPad, or did you download it to iTunes on a computer and sync it to the iPad?

.mov files play in quicktime 10 but not quicktime 7

i have .mov files that I made in the qt version before 7
I upgraded my OSX to 10.6.7
I purchased the Pro version of QT 7
It will not play my .mov files
However, my other machine that also runs OSX 10.6.7 has QT 10 installed and it plays the movies
So...
I tried to find Quicktime 10 to purchase on the Apple site and they do not sell it
will it be on my snow leopard install disks?

Compare the audio and video compression formats used in the MOV files against the QT component configuration of the two systems in question. You will likely find that the codec components needed to play the MOV files are not installed on upgraded system or the have broken paths or simply need to be updated to work correctly with the non playing system.

It is installed by the Snow Leopard installer but is not stored as a separate application. (I.e., it would have to be extracted from the Snow Leopard installer package but cannot be installed on non-Snow Leopard operating systems.

Cannot get movies to play.

The screen appears with slider control as if playing but no image or sound while playing a movie; songs play OK. Also discovered in "Sharing" mode (in Preferences) a separate "News about Fracking" line that is obviously not related to any movies, songs, books, etc.; did not activate sharing as this may be viral. Could all of this be related? If so, how do I resolve this or must I completely rebuild the OS? I have a PowerBook G4 running OS 10.4.11.

hi steadyone,
Thanks for posting!
Can you share Where are you getting the Videos,
Are they online streamed video like youtube etc... or Downloaded Videos to your Tablet, if they are downloaded what type of format avi, mp4 etc...?

QuickTIme won't play movie only on just one page!

Good morning all, My Brother has a iWeb site where he shares with me videos of my nephew's on only on just one page the quicktime logo with a question mark shows up and won't play, yet the same page will play on my iPhone. Could anyone guide me through I might be able to fix it? I really want this page to load so I can save the video of my nephew. I've reset the cache, reset safari, repaired permissions. Not sure what to do. I'm nervous about reinstalling quicktime from the Apple site because it doesn't say anything about Quicktime X, also I tried opening the URL in Quicktime Pro, but that didn't work either. It's just this one page that won't load right! Thanks so much for your help!

What is so frustrating to me is I am trying to view a website made and with iWeb09 and the videos in the site hosted by MobileMe are shot with an iPhone3GS! I just can't figure out why the only video's that won't play are from my brothers website. He has tried visiting his own site and they play fine, and it plays fine on my iPhone! Is there some setting somewhere I am missing?
Based on the fact that content plays on your brother's computer, as well as, your iPhone, the most likely source of the problem would be your platform configuration. While I can understand it may not be desireable for the general public to have access to your family's personal web site, knowing the specific compression formats and actual settings used in the uploads is often key to deteriming the specific problem and solution here. And, while the list of players and components provided by Baby Boomer normally handles 96-98% of the content you are likely to encouter, it does not help to identify your individual problem.
Basically it would appear that some component or plug-in on your computer is not functioning or installed properly. Many users who have upgraded to Snow Leopard have reported that some add-on codecs (e.g., the QT MPEG-2 Playback Componet, Perian, etc.) are not properly re-linked to the new OS and have to be re-installed. In a similar manner, if there was a problem during the Snow Leopard installation, the regular system components could be missing or corrupted. By knowing the specific compression formats involved, it might be possible check to ensure that they are/were installed in their proper location and/or test their current servicability within your system. In addition, you may want to download the source files to see if the play correctly locally to determine if the problem is in the codec, your browser, a plug-in that may be needed to support the browser, or some sort of conflict (e.g., common component conflict as described on the Perian site).

QUICKTIME WON'T PLAY MOVIES???

Does anyone else have the problem with Quicktime 7.4.5 not playing any type of movies (mov/mp4/avi)? Until the latest update for itunes/quicktime I had no problem playing the movies. Now I keep getting "Error -50: An unknown error occurred (name of movie.extension)". Most of my movies were converted from .flv to .mp4 then saved with quicktime to .mov. I used "Replay Converter". Again until today, quicktime had NO problem playing any of these files...now it can't play any of them.
Any suggestions?

For a long time, there was a bug in the conversion of .flv's to .mp4 in the ffmpeg libraries. This caused any app that used ffmpeg to create non-standard .mp4 files. This bug has now been fixed and everything should work as normal. However, those older files that were not created according to the .mp4 standard won't play when they have an .mp4 extension.
On the Mac side, an app to fix these have been released, I don't know about the PC side. Others have noticed that if they change the extension to .3gp, they will play (and they're reported to play in iTunes as well).

I recently purchased QuickTime 7 Pro to convert avi files to mov files for editing on Imovie. However, QuickTime won't play the files. How can I get them to play and how can I convert them to mov files?

Both the AVI and the MOV file extensions refer to the file container and not the compressed data the file contains. Both are generic file containers in that each may contain any valid combination of audio and/or video data that is compatible with the codec component configuration of the system on which the file was created. On the other hand, whether a file is playback compatible, conversion compatible, and/or edit compatible depends on the data actually contained in the file container. So, you are basically dealing with two separate issues here—the container and what is inside it.
Basically, if you want to make your files ediit compatible with iMovie, you must change your file container to one that is acceptable to iMovie and convert the data to edit compatible audio and/or video compression formats as may be necessary. The best approach is to determine what codecs were actually used to create the original AVI files and add them to your system if possible. In most cases a codec package like Perian can be added to your system's codec component configuration to may the AVI file playable. Once they are playable, in the QT 7 app then they can be chnged or converted to file types and compression formats that can be edited in iMovie. (While Perian handles most codecs commonly used to create AVI files, it does not handle all possibilities and, while the Perian codec package still works under cureent Mac OS versions, its development group has decided to drop further development/support of the package.)
Background: AVI is a file container originally developed by Microsoft back in 1992 but for which official support was discontinued about 11 years. Despite its limitations, Windows users still tend to use this file based on its open source ease of use and generic nature, thus, making its use so popular that most users are unwilling to switch to more modern but less generic file types. Since some AVI legacy compression formats have never been transcoded for the Mac or use beyond OS 9 or OS X PPC platforms, it is often important to know what specific compression formats are contained in the AVI file to know which codecs to add to your system and which not to add in order to avoid possible codec conflicts.
You can use many different converters to convert AVI files to iMovie edit compatible files. Most third-party apps contain their own buit-in codecs which do not relay on the Mac codec component configuration. Free ones, like HandBrake, usually have limited conversion capabilities while those that have more varied outputs are usually commercial in nature and will cost you additional cash. QT 7 Pro or the free MPEG Streamclip app allow you to access you own system's component configuration and use any available codec component like DV, AIC, MPEG-4, H.264, Photo JPEG, etc.—all of which are iMovie compatible for editing purposes—but only after making the AVI file QT 7 player compatible.
In order to determine what compression formats wewre used in your AVI files you can
1) Try checking the Finder "Info" window,
2) Use the "Inspector", "Media Info", or "Properties" window of any player app that will open the file, or
3) Use a general media utility app like "MediaInfo" to read the file characteristics.

Quicktime won't play my .mov files since I upgraded to Mavericks.

Quicktime won't play my .mov files, even those from an iPhone, since I installed Mavericks. "Tell Me More" doesn't tell me anything about a solution. Any suggestions?

What do I do?
Frankly, if you have deleted the original movie clips from your camera/camcorder and iPhoto, then it sounds as if you are up the proverbial creek without a paddle and there is nothing further that you can do.
Some facts:
For some reason, the movieclips are awful small (13-30 KB).
640 x 480
Codecs: H.264, AAC
While these facts are of little value without file duration information, as you yourself have already noted, the file sizes quoted are extremely small. A typical VGA H.264/AAC file of reasonable quality would normally have a combined total data rate in the 700 to 1,700 Kbps range depending on specific settings, profile, and level of the encoding software and could be even higher or lower depending on the quality levels required. Therefore, it is reasonable to assume that files in the 13 to 30 KB range only contain 104 to 240 Kbs and either have durations measured in fractions of seconds or do not actually contain enough data to be played. (E.g., the video data may be missing or the file is corrupted.) Thus, it is most likely that something was wrong with the workflow used to "export" your files to the external drive and when you ignored the fact that the files were not playing correctly, you closed the door on anything that you could do when you deleted the source files. (I.e., the normal workflow here is to copy the entire iPhoto library to the external drive, switch libraries, confirm the new library is working properly and only then delete the boot drive copy of the iPhoto library.)
OBS: When I try to convert the files into something else (AVI, MP4 whatever) either it comes with an error, nothing happens or the converted file wont open. This happens with various convert-programs.
If the data in the files is missing, then there is nothing to be converted by any application.

Why won't QT play this .mov file?

The below movie won't play in iTunes, QT, QT 7 Pro, or VLC. QT says I'm missing a 3rd party add-on or plug-in. I've tried to convert it with DiVX and it goes through the process, but the resulting file opens as a movie, but only shows a black screen with the audio.
Can anyone tell me what is it about this file that makes it unplayable? Here's what's in the info window:\

I appreciate the input.

Alright...some new info. I found two files in iTunes--one would play and the other wouldn't. I tried to open each in QT, QT 7 Pro, VLC, DiVX player, with the same results--one worked, one did not.
I opened Get Info on each .mov file and EVERY IMPORTANT DATA POINT was the same.
Kind: QuickTime Movie
Dimensions: 640 x 480
Codecs: H264, ACC
Color profile: SD (6-1-6)
Audio channels: 1
I could Read and Write on both.
So how would one file play and the other one just play audio?
I'm obviously missing something. I'd truly apprecate some insight.
THANKS!
