Quicktime Player won't play avi files all of a sudden

All of a sudden Quicktime Player won't play my avi files. They worked previously. I could play them with Quicktime 7 with or without Perian. I'm running 10.6.4.
They'll run fine on my MacBook and I don't have Perian installed on it.
Any ideas?

I just uninstalled Flip4Mac and everything is working as it's supposed to. Very strange. Perhaps a conflict with Perian? But then again, QT didn't play the avi files with Perian installed. So, I guess the conflict is with Flip4Mac and something else.
Thanks anyway

Quicktime player won't play avi files.

Hi Guys,
My MacBook Pro is amazing and all but when I try to watch or open an .avi file it tells me this:
Yes I did click on the "Tell Me More" button and downloaded the Dvix Plugin but after all the trouble of downloading everything the .avi files still don't play...
Please Guys help me out....
Thanks,
Lucas

It will be through VLC. VLC is worth having as it enables you to play lots of media formats that are not otherwise supported on the Mac.

My QuickTime player us not playing .avi files and says I need a codec I can't play no .avi files on QuickTime. How could I fix this because I want to play these files with QuickTime.

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.

Quicktime 7 won't play avi files

can someone please tell me why this is?
It's only stopped playing them since its been upgraded
i just get a white screen and the message that there might be a missing component?
Sorry if this question has already been posted!
Please HELP
iBook G4 Mac OS X (10.4.8)

If QuickTime is set to play avi files in System Preferences, then the avi might not be one that QuickTime can play. There are several proprietary avi codecs. You might try VLC player or some other player that can play all the different kinds of avi codecs.

HT2305 just downloaded quicktime player, tried to play avi file and all I had was a black screen. HELP!

I'm just after attempting to play an avi file with Quicktime player on windows7 and all I got was a blank screen. Is there any particular reason that this is happening, or is quicktime incapable of playing avi files without going pro?

The QuickTime Player doesn't have the right codec for that specific AVI. Purchasing QuickTime Pro will make no difference; it doesn't contain any additional codecs.

Quicktime X won't play .avi files

I have several video files that are in the .avi format, and Quicktime won't play them. Every time I try to open them it says 'the movie can't be played'. I have visited the support site on Apple after clicking the 'Tell me more' button on the dialogue box that appears. I have downloaded Perian, Flip4Mac and DivX, none of which have solved the issue. I can't even open the file in Quick Look - it just plays the audio and not the video.
Does anyone have any ideas? Please help.
Thanks

VLC also does not play the file. The error message I receive when trying to open in VLC is: "VLC does not support the audio or video format 'VP70'. Unfortunately there is no way for you to fix this." I also have the option to show details, so if they would be helpful then I'll post them, but I hope there is enough information in this post for you. Any other suggestions?
Thanks

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.

Quick Time (Mountain Lion) won't play .AVI files.

Since all of you probably already know the information I typed in the headtitle, I have a question. So obviously .avi files can not be played on this version of Quick Time that comes with Mountain Lion, but, would buying a Quick Time Pro solve my problem? I'm ready to pay 30$ for the program, but first I'd like to know would it enable me to play .avi and all sorts of other video files? Ofcourse I read it does play all sorts of files including .avi, but I'd like to hear it from somebody who actually uses Quick Time Pro on Mountain Lion. Thanks for your help in advance!

P.S. I already have tried VLC, I use it but that's not the solution I'm asking for. Nor that, nor other programs such as MplayerX. I'm interested only in Quick Time while it never breaks, deinterlaces my footy nice and is very simple and user friendly.

You don't need to buy Quick Time Pro. Quick Time Pro is just a paid add-on to add features to QuickTime Player 7. You don't need the Pro features for just playing. The player in your Applications folder is Quick Time X. QuickTime Player 7 should be in your Utilities folder (which is inside yoir Aplicatioins folder). If it's not there, download it from:
<http://support.apple.com/kb/DL923>
QuickTime Player 7 will play .AVI files if you install Perian
<http://perian.org>
then replace its A52 codec component

HT3775 Quicktime 10.2 (603.6), it won't play .AVI files

I have Quicktime 10.2 (603.6), it won't play .AVI files, tells me "file format isn't recognized" the above article says it does play .AVI files, what gives?

There isn't a codec installed which can handle that specific AVI file; AVI is a container, not a format. Try installing Perian.

My quicktime player won't play any videos on my Mac X os. The video will start on quicktime then automatically start

My quicktime player won't play any videos on my Mac X os. The video will start on quicktime then automatically start. I installed DiV X today and all this happened is there anyway to fix this?? I went through everything dragging the icon to the trash and deleting it from safari extentions.

Download and install
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs. In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them), particularly any DivX extension to Safari. However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/en/software/mac Note that Perian will be discontinued after the release of Mountain Lion: http://reviews.cnet.com/8301-13727_7-57434082-263/perian-plug-in-for-quicktime-t o-be-discontinued/?tag=txt;title

HT5271 Downloaded latest Apple updates that informed me old versions of Adobe Flash Player were disabled and advised me to go to Adobe and down load latest version of Flash Player. Did that, but Flash Player won't play swf files, which it did before.

Downloaded latest Safari update that informed me that older versions of Adobe Flash Player were being disabled and then advised me to go to Adobe and down load latest version of Flash Player. Did that, but Flash Player won't play swf files, which it did before. (Instead of opening, it comes up as a page of code).

Hi..
Quit Safari.
Open System Preferences > Flash Player then select the Advanced tab.
Click: Delete All
Now select the Storage tab.
Click Delete All
Relaunch Safari to test.

JMStudio won't play .avi files - mpeg-2 works fine

Why doesn't JMStudio play .avi files?
A small application that I created with JMF 2.1.1 has the same trouble.
My .avi files can be played successfully with mediaplayer and also zoom player but JMStudio chokes on them. Why?
I want to create a two-pane player for side-by-side video comparison with JMF but I don't want to start the effort if simple .avi playback is not possible.
Sun's JMF 'supported format' page shows that all forms of .avi are at least 'playable' - yet my files are not.
I have several mpeg-2 files that are playable in JMStudio and also in my simple app - so I know that the code is working.
There are several old threads on this forum that ask this question but none of the threads give a decent answer.
Please help.
Thanx,
skigrinder

Got it working.
Apparently, JMF can't handle type-1 .avi files but it can handle type-2 .avi files.
Nero and Sony-DvGate both create type-1 .avi files in the capture process from a DV camcorder.
I found a (Windows) utility - DvConverter - that will convert a type-1 .avi file to type-2.
I'm now able to play these type-2 .avi files in JMFStudio and also in my own prototype player.
Surprisingly, the FramePositioningControl functions also work - skip() and seek() !!!
I'm currently working on eliminating the 'comb-teeth' effect that exists in both JMFStudio and my own player.
I've read that this effect is the result of interlacing artifacts but my experience has shown that it also has a lot to do with the codec that's running. In windows, installing, un-installing, and re-installing codecs has a tendancy to mess with the registry in unpleasant ways resulting in a lot of time wasted trying to get rid of this 'comb-tooth' effect.
Andrew, do you know of a foolproof way to solve this problem on windows?
Thanx,
skigrinder

Quicktime Player - won't play movie

I have a movie file which works on my old 10.6 Snow Leopard machine (it's a m4v file), but Quicktime player under 10.8 refuses to play it. Whenever I try to open it, it complains of a missing codec (but doesn't state what). However I can watch the preview in Quicklook. If I try to watch it in VLC, the sound comes out all distorted and sounds like something from the 80s, while the 10.6 machine plays it nicely.
I've tried to copy it via various methods incase it's getting corrupted in transit, but I get the same result.
Any tips or recomendations for a movie player that might play this file?

Hi Sam,
.m4v is the format and codec is the component / resource used build the movie i.e m4v is a box that is carrying the movie and the movie was created using codec like MPEG or MPEG2 or H264 and so on...
http://perian.org try to get this App or http://mplayerx.org/download.html, try to update your VLC player....
Good luck...

Quicktime player won't play iMovie 09 export m4v

I exported a movie from iMovie 09, produced a .m4v file.
QuickTime Player 7.6.2(518) with QuickTime 7.6.2(1327) plays this with serious stutters in the playback every few seconds.
Current VLC and Plex play the file back without any problem.
Is there some update or plugin I need to fix this?
Thanks --- Sophie

I find that with recalcitrant .m4v files, re-exporting from the original base file as an H.264 then renaming the file extension as .m4v so as to fit in with the scripting that is automatically generated when exporting with for the web option results in a larger , but generally more compatible file.
Might cure some of your blues, plus the .m4v is just Apple's .mp4 and Apple's MPEG4 doesn't seem to have the 'common touch' required, all told

Quicktime Player won't play Sketchup animations

After switching to Lion, Quicktime player renders animation .mov files exported from Sketchup as just black. I can get the movie to play by importing the .mov file into Final Cut Express, then re-exporting it as a .mov from that program. After doing that Quicktime Player plays the movie okay. What gives? Using OS10.7.2, Quicktime 10.1, and Sketchup 8 on a Mac Pro.

I just uninstalled Flip4Mac and everything is working as it's supposed to. Very strange. Perhaps a conflict with Perian? But then again, QT didn't play the avi files with Perian installed. So, I guess the conflict is with Flip4Mac and something else.
