You can also use VLC

It woks very well, can read almost anything, and also lets you do conversions to other formats.

Quicktime will not play .mov files since Lion installation

When using Quicktime 10.6, I am receiving the error message "...file could not be opened. A required codec isn't available." when attempting to open .mov files. Prior to installing OS X Lion, there were no issues with playing .mov files.

I'm having the same problem. Using a clean install of Mac OS X (10.7) Lion and QuickTime 10.1.
If I go to finder:
I can click on Icon's Play arrow and the Movie will play in the icon.
I can click on the file icon and press the spacebar and the file will play in QuickLook.
If I doubleclick on the icon to open the file in QuickTime, I get the "...file could not be opened. A required codec isn't available." message.
If I right click on the icon and click open with... QuickTime, I get the "...file could not be opened. A required codec isn't available." message.

HT3775 I am using OS X Mountain Lion and I have this .avi file but not able to read. What is missing in my setup and what other file do I need to download to enable me to read? I can read mp4 files though.

I agree that VLC is also a good choice but MPlayerX is more user friendly.

Hmm . . . comes with a Utility MPEG2 Component ML app with no explanation of what it's for?
The utility app is an "assistant PKG installer." It allows Lion and Mountain Lion users to install the older QT MPEG-2 Playback Component installer PKG file which is not allowed to run on its own under Lion or Mountain Lion since these operating systems already have a QT X only MPEG-2 component embedded in the QT embedded structure. Without this utility you would have to either copy the component from an older system to your Lion or Mountain Lion system, use Pacifist for installation, or manually open the PKG contents and transfer the component to the appropriate component folder.
As to your "discussion" regarding the playback of AVI file types, there are really only two strategies here:
1) You can add component support so that QT can play the files natively or
2) You can convert the file contents to compression formats that are natively compatible with the unmodified QT component configuration.
Each user should decide for his or her own self which approach best suits their needs for a particular source file. In most cases, conforming the system's codec component configuration to play the source file directly results in higher video quality since no transcoding takes place but this strategy will not work if a codec which is required is not available for the user's operating system. On the other hand, converter utilities tend to support more built-in codecs and are easier to use since the user does not have to concern him or herself with the nature of the particular source compression formats but at the risk of some potential loss in visual quality. As to what converter to use, once again this is a matter of personal choice. In the case of commercial converters like iSkysoft, the codecs are built in while MPEG Streamclip accesses the host operating system's QT codec component configuration. I personally prefer the free HandBrake app for AVI, MKV, TS, MTS, and M2TS conversions since it has an exceptionally full-featured X.264 GUI with some user options that 97% of users are likely to never use.

HT3775 My Macbook Air (still with Lion) will not play .avi video files

My Macbook Air (still with Lion) will not play .avi video files (brought over from an older PC where they play with another viewer). This site implies Quicktime Player should be able to do so. Is there a codec or something else I'm supposed to download?

I had found this through other threads, but it is what worked, even allowed my AVI files to be played in PowerPoint. Changing to 32-bit encryption did not work, BTW.

Depends of the specific kind of file you are trying to play. MOV refers to the file container. Any data compatible with the system used to create the file can be placed in an MOV file. If you don't have the same codecs available on your computer to play back the file or if your version of the QT player does not expect expect the encoded data to be in an MOV file container, then it cannot/will not play the file. Use the Finder Info window, media player Inspector/Information window, or a dedicated utility to determine what compression formats were used to create the MOV file and then install the required codec(s) if available.

Help major issue, quicktime will not play my HDV movie?

I have a major problem here.
I have a movie i shot and edited when I was at university using Final cut pro and HDV cams.
I need to show this movie on my macbook pro, but I purchased final cut express, and have just found out my Quicktime does not play this file.. the screen is just black?
I assume I need a HDV 1080i50 codec for quicktime??? is this correct?
Where can I get it?
I intend to give a presentation was going to use OpenOffice or use my Quicktime just for moving image
Any suggestions?
Regards

You were given a video that can only play in Final Cut Pro. Final Cut Express doesn't have that codec.
You going to have to go back to whom ever gave you that video and have them export the video to a codec that either Final Cut Express can play or a codec that Quicktime can play.The later would be better because, if a video can play in Quicktime it can play in Final Cut Express.

It looks like you may need a mini-displayport to Displayport cable. You can also try holding the option key while clicking on "scaled" to see if the option you need comes up.

After recent QuickTime updates fcp and QuickTime will not open .mov files captured on my FS-H200. Iran

After recent QuickTime updates fcp and QuickTime will not open .mov files captured on my FS-H200. I put this onthe quick time thread and they sent me here.

and NEVER do a software update unless you've got a clone of your startup drive so you can restore your system to it's working state if something goes wrong.

I use my camera for video and photos. When I download my videos to my ipad1 using the camera connection kit, they will not play on my ipad. Is there a way I can get them to play?

I use my camera for video and photos. When I download my videos to my ipad1 using the camera connection kit, they will not play.
Does anyone know how I can make this work?

Yvonne-
I haven't tried videos on my camera yet. Do you use the Videos App to play them? I don't think they will play in the Photos App.
If yours are in a format that is not in Vazandrew's list, you may need to sync them to your computer and convert them to M4V or MP4 format. You can use a program like HandBrake to do the conversion. <HandBrake> Once converted, you can sync them back to the iPad and they should play.
This may not meet your needs, but the alternative appears to be getting a different camera. I don't know of another Video App that might work.

Quicktime will not play MPEG-2 after Lion updagrade

I have upgraded my system to Lion which should enable Quicktime to load MPEG-2 videos yet I cannot "missing codec" - does anyone have a possible solution?

These are files that were stored on my previous Windows computer as AVCHD and utlised a Sony program (Picture Motion Browser - PMB) to view. The PMB had a facility that allowed me to convert the files to MPEG-2 (.mpg) which I did. I then transferred these files across to my iMac.
Are you sure the content is MPEG-2? AVCHD data can be stored in an MPG/MPEG file containers without transcoding but would not be recognized by Lion's QT X Player software. (I normally use the MKV file container for such data.) Try playing it in VLC and if it loads and plays without problem check the "Media Info" window to view the compression formats.
When I open the .mpg QT is launched but then the error regarding the missing Codec comes up.
Which version of QT? Lion can simultaneously use both QT X and QT 7 players. The one that opens automatically could be either depending on whether or not you have modified the default "Open with..." setting for the MPG/MPEG class of files.
I have the Lion OS which I am to believe updates QT to enable it open MPEG-2 files.
As previously stated, only QT X natively supports MPEG-2 compression. QT 7 MPEG-2 is not supported by Lion's QT X software and so, as previously mentioned, it still requires the $19.99 QT MPEG-2 Playback Component be installed.
I have also downloaded the QT MPEG-2 Conversion from the apple store however it will not install on my computer as it says I need an older version of my OS before it can proceed.
If by "QT MPEG-2 Conversion" you are referring to the QT MPEG-2 Playback Component, only the installer will not run. The component itself is compatible and can be installed in one of three different ways:
1) Install the component on an older system and then copy the component to your Lion system.
2) Download and use the free MPEG-2 Streamclip Beta package software to install the component. (I.e., this software package includes a "helper" utility that will install the QT MPEG-2 Playback Component which is in the installer package you purchased from Apple but which will not run on its own.)
3) You can use Pacifist to either auto-install the component from the MPEG-2 component installer package or to extract the component and manually install it yourself.

Quicktime 10.1 not playing .avi files

My quicktime player isn't playing .avi files properly. I have perian installed and have been playing .avi files on my MacBook Pro fine now for over 2 years. However, I resently installed Lion and it doesn't seem to be working now. I've looked around and it seems there are some bugs with Perian and Lion, however I haven't seen mine. Quicktimes loads, loads the video, I can click anywhere on the timeline and see the video, however when I hit play, it immediately pauses itself and won't play. Sometimes it will play very brieftly, about 1/10 of a second, and then flicker back to paused. Is there any other integrated solution to Perian? Was hoping to not have to get VLC player.

I had this same problem and someone on here helped me solve it.
As stated, I did not have any problem and could not duplicate the original poster's problem.
See if you have DIVX For Mac installed.
Negative. I do not have any DivX components installed and am using Perian for playback. AVI (DivX5/MP3) files were created using Visual Hub under Snow Leopard. And, if I cannot get Visual Hub to work under Lion (PPC version is not Lion compatible), then I will drop AVI altogether since I only use it to send my sister clips.

I have just upgraded to OSX 10.6.8 and now I cannot open or save PDF files from the internet. I get a dialogue box saying the QuickTime plugin has failed. I have tried to download the latest plugin but this doesn't work. Can anyone help?

I have just upgraded to OSX 10.6.8 and now I cannot open or save PDF files from the internet using either Safari or Firefox. I get a dialogue box saying the QuickTime plugin has failed. Can anyone help?

Is this what you downloaded: iTunes 10.7?
When the update fails what if any error report do you get, specifically? Please do this before trying again:
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
