QuickTime 7.0.3 Muxed file support. When?

Hello, I have been learning about how to save many different media formats into either *.3g2 or *.mp4. I finally understand it now and the only thing that frustrates me is the fact QuickTime Pro is useless on files that were once Multiplexed in the past. Does any onw know if Apple is aware of such Problem? There is simply no way to export, let's say, a Muxed Mpg1 file to *.3g2 or *.mp4 and keep the audio. The part that kills me is that I have found a Free ware tool on the net that does it but the Audio is somewhat not as in sinch as it should be.
This problem is completely software related and there's no need to give hardware specifications.
I hope there's an answer out there.

Apple has for several years made available a FAQ that lists this export limitation so it is unlikely that they are going to make any changes.
QT Mpeg Limitations
However, there are solutions, such as using this freeware Windows program that can convert mpeg-1 files to avi format which can then be opened in QT and exported with both video and sound to your choice of formats. Just open the mpeg-1 file in VDub and then use Save as Avi in the File menu. Note that the uncompressed file will be quite large, so if it is a long mpeg you may need to do the conversion in several segments.VirtualDub

Exporting Muxed Files in Quicktime Pro 7 w/ MPEG-2 Component

I have .mpg files I need to be able to get into iDVD. They are MPG-2 muxed files. I have quicktime pro and the mpeg-2 component. I can't for the life of me figure out how to do this. Everyway I try either fails halfway through or I get no audio. I've trying to convert them to Mpeg-4. The answer is probably easy but I am new to Mac. any help would be great.
thanks

As you have discovered, QT does not support the export of sound from muxed mpeg files. Fortunately, this freeware will export to several formats. It also allows you to do some editing of mpegs without re-encoding if that is desired: Mpeg StreamClip

I am using OS 10.7 Lion. Quicktime will not play avi files. One support forum gave 2 links to get them but I got a 404 error. Can anyone help?

You can also use VLC

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

Are .mp4 files not supported when trying to merge 2 videos into 1 video?

Are .mp4 files not supported when trying to merge 2 videos into 1 video? The steps in the manual seem simple enough. But the paste function won't work on the 1st video after selecting all and then copy on the 2nd video.

There are 9 different versions of iPhoto and they run on eight different versions of the Operating System. The tricks and tips for dealing with issues vary from version to version and OS to OS. So before anyone can help, they need information to work with. Things like:
- What version of iPhoto.
- What version of the Operating System.
- Details. What were you doing when the problem arose?
- Did it ever work properly?
- Are there error messages?
- What steps have you tried already to solve the issue.
Anything else you can think of that might allow someone else to understand your issue.

Will Quicktime Pro convert/compress .dv files to Quicktime?

I have .dv movies that are taking up so much space on my hard-drive. I purchased Quicktime Pro to compress those files so they will take up less space. I don't see in the tutorial how to do this. Could someone please point me in the right direction so I can see how to do this? Thanks!

Will Quicktime Pro convert/compress .dv files to Quicktime?
Of course.
I don't see in the tutorial how to do this. Could someone please point me in the right direction so I can see how to do this?
This is impossible to do until you define what you mean by "QuickTime."
Basically, a "QuickTime" (MOV) file is any form of dat that can be placed in an MOV file container -- not a compression format in and of itself. Therefore, your first step is to determine what you really want to do here. For instance, a DV (.dv) stream file normally consists of an audio DV compressed track along with a video DV compressed track. DV(25) files normally contain audio and video tracks having a data rate on the order of 28.5 Mbps each (or about a 57 Mbps total average data rate). As you indicated, these do make for rather large files. You could, of course, reduce the total data rate by nearly half if you merge the original video track with AIFF (linear PCM) converted audio (or even smaller if you use an AAC audio track). The catch here is that QT Pro does not have a DV "pass thorough" video option which allows you to simply convert the audio while retaining the original DV video. So unless you are willing to manually convert the audio track and then manually replace the original Audio track with your converted audio, you would normally have to convert both audio and video to another compression format.
In this latter case, you could select any valid codec supported by QT as augmented by installed components. Typical possibilities would be AIC/AIFF, unlimited H.264/AAC, Motion-JPEG/AIFF Photo-JPEG/AIFF, supported MPEG4/AAC or H.264/AAC profiles with limited data rates. These compression options are all compatible with iMovie '08 editing and represent a full range of possible data rates (which in turn determine your final file size). For instance, an AIC/AIFF file would normally end up with a total data rate on the order of 20-22 Mbps with an unlimited H.264/AAC about 16-18 Mbps, M-JPEG 10 Mbps, Photo-JPEG 8-9 Mbps, and MPEG4/AAC or H.264 as low as you can stand the loss in quality and still retain a video track.
These various compression formats basically represent a compromise between file size and quality with the quoted data rates being typical for SD content with an "average" quality setting. While actual data rates are always dependent on the actual file converted, the stated averages should provide some idea as to what you could expect in comparison to your original source file -- i.e., the AIC/AIFF file would be expected to be about 62-65% the size of your DV file, unlimited H.264/AAC 28-31%, M-JPEG/AIFF 17-18%, Photo-JPEG 14-15%, and MPEG4/AAC or H.264/AAC in the 3-5% range with "reasonable" quality levels.
Since each codec has somewhat different characteristics and user options, I will not go into specifics for each here. What I would recommend at this point is for you to select a short file with typical content and convert it wising the various codecs and determine what compromise in file size and quality you can live with at the display size you plan to use. This in turn will likely depend to some extent on what you plan to do with the final file. For the archiving of files for later use/editin, you like want files to retain as much quality as possible which, in turn, usually implies large file sizes. On the other hand, distribution files can be much more highly compressed as a "finished" product which you don't intend to re-compress or edit further. Remember, when you compress a file more compact format you are literally "throwing away" data so you should be most judicious in selecting that appropriate format to which to compress your files for the saving of file space.

QuickTime stutters only with .mpg files

Only since I've updated to Mac OS X 10.5.2 that I've been experiencing this problem. I have a load of .mpg files recorded using my digital camera, as well as a bunch of files I've downloaded from the net. These used to play back perfectly fine and smooth in QuickTime, but now every few seconds there is a big stutter. The files aren't corrupt as every other media player plays them fine. Also, it is just .mpg files QuickTime is struggling with, any other supported format plays perfectly fine.
The file codec is 'MPEG1 Muxed'.
I've tried reinstalling QuickTime, the Leopard Graphics update and neither have provided me with any fixes.

Why did you uninstall Perian? You need it!
These are the downloads and the settings you need in order to view/hear pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!
It is known to work in the great majority of cases with Safari 3.0.4, QT 7.3 or 7.4 and OS 10.4.11. (If you are running Leopard, ensure that all plug-ins have been updated for OS 10.5.2, but please see my footnote).
Assuming you already run Tiger versions OS 10.4.9 or above (this has not yet been verified with Leopard) and have Quicktime 7.2 or above, and are using Safari 2 or 3, download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
RealPlayer 10 for Mac from http://forms.real.com/real/player/blackjack.html?platform2=Mac%20OS%20X&product= RealPlayer%2010&proc=g3&lang=&show_list=0&src=macjack
Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs.
Adobe FlashPlayer should first be uninstalled using the appropriate uninstaller available here: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157&sliceId=2 and then the latest version obtained from here: http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash and installed.
(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS, but please see my footnote if you are running Leopard.)
In earlier versions than QT 7.1.3 in Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).
You should also ensure, if you are running Tiger 10.4.11 or Leopard, that you have downloaded and installed the correct version for your Mac of Security Update 2007-009.1.1, which also deals with the Quicktime/Flash issues you may have experienced, such as the '?'. What happened was that both Quicktime as well as Adobe FlashPlayer tried to play the Flash video at the same time. This no longer happens. (N.B. Security Update 2007-009 1.1 requires both a restart and a permission repair.)
If you get problems with viewing video on a website try moving this file to your Desktop:
Hard drive/Library/Internet Plug-Ins/QuickTime Plugin.webplugin
and then restarting Safari. If all now works, you can trash that file.
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them). 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/divx/mac/
Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them) to enable Java.
Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz, and that you have selected 'Built in Audio'.
Important: Now repair permissions and restart.
You should also consider having the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.
FOOTNOTE
If you are running Leopard:
Some users have mentioned that the latest Flash Player (v.9.0.115.0) conflicts with Leopard, and that they have needed to revert to v. 9.0.47. This can be downloaded from here:

Mpeg2 issue ---- muxed files

I'm having an issue with my Quicktime Pro with the MPEG2 plugin.
When I open this file format: MPEG2 Muxed, 480 x 360, 29.97 FPS, it plays the first few seconds then freezes the frame. The audio still goes on but I have no picture.
Now on the website for the MPEG2 plugin, it says that QT will play MPEG2 files muxed and all, but it's not for some reason ^_^ And also I want to pull those files into iMovie HD (iLife 05) and it doesn't want to pull in the files either.
I have found that Toast will actually make me a DVD no questions asked, but I'm looking to edit the videos. They play in VLC fine and will transfer over to MGEG4 alright, from VLC, but the more I step on the footage and compress and recompress, the crappier my video looks on the TV.
Can anyone help me find out how to get my stuff to play or be able to edit with-out all this recompression? Right now I have to convert to .mp4, insert into iMovie, fix, export to iDVD and compress back into an MPEG2 DVD friendly. Or....go from .mpg to BitVice and try to edit in iMovie with .m2v when it just mysteriously doesn't want to work this time with .mp4.
I'm getting a little frustrated! Can you please help? Thank you!!

What kind of editing do you wish to do? If all you need is limited editing capabilities (e.g., trimming segments, cropping and/or scaling, adjusting the volume, brightness, contrast, and/or saturation), then a free application like MPEG Streamclip (woring in conjunction with the MPEG-2 component which you already have) may be all you need. Note however, that if you wish to work entirely withing the MPEG "muxed" file format, you will be limited to just trimming your segments and saving them. Other editing capabilities mentioned are usually performed as part of a conversion process. If you wish to perform more complex edits, apply special effects and or mix the media with phtographs, music, add transitions and/or fades, etc,. then you can use this application to convert both audio and video to either a continuous DV stream (compatible with the current version of iMovie) or segmented DV streams (compatible with older versions of iMovie).

Mpeg 1 Muxed files

I understand that when you import "muxed files", (I have no idea what that means) you only get the video, no audio. I have some Quicktime movies like this. Is there a way I can change the format of the file so I get the audio too?

MPEG Streamclip (free) can export muxed files to QuickTime formats and include the audio.

Quicktime doesn't open AVI file with Perian installed

I have installed Perian but Quicktime X doesn't open AVI files for a week. I have repaired permissions. But Quicktime only plays the AVI file if I reboot the Mac. VLC always plays the file. The AVI codec is XVID. Quicktime doesn't play other formats such as FLV. I have deleted .plist files, com.apple.QuickTimePlayerX.plist. I have found other files(com.apple.QuickTimePlayerX.plist.0GH3f31, com.apple.QuickTimePlayerX.plist.0h9MBzV...) that I deleted also. Any idea? Thanks

And now ... surprisingly I view AVI files in Quicktime without Perian.
QT has very limited AVI support (file type and a few older codecs) built in. Most common codecs use by Windows users, however, require the additional support provided by Perian. If the AVI files are now playing in QT without Perian, then simply check the Inspector, Properties, or Info window to see which codecs are in your AVI file and you should be able to tell if they are among those supported "natively" by QT. Also note that this regaining of the ability to play your files may indicate a component conflict of some sort may have existed previously.

thank you,

I ended up on the phone with an Apple iPhoto expert after scheduling an appointment online (go to Apple support). He spent an hour or so diagnosing my particular problem and was able to fix it. I can once again view all my mov files in iPhoto. Since every computer is different, you might want to try that route. He was able to view my computer screen and direct me to do different things.
