QuickTime Mpeg2 Playback is jerky

I purchased the MPEG2 playback plug-in.
However, the playback is jerky...seem to stop and go...
I played with the video playback preferences...
I do not have this problem with other file types or with the same files playing back on Microsoft Media Player

Hi pabo88,
I just ran into this in iMovie. Exporting a QT .mov resulted in jerky playback in QT. I exported a Full Quality .dv file from iMovie and it played fine in QT. Then I exported out of QT as a .mov. It only works if you have QT Pro, but it works!

Quicktime MPEG2 playback component

I've purchased and downloaded Quicktime MPEG2 playback component but I can not openend, the system says that Quicktime MPEG2.dmg is not recognized. Can anybody help me with this issue?. Thanks.

What app are you using to try and mount the image file? The default should be the DiskImageMounter.app application. If it is still the default app, then it sounds like the image file, the mounter app, or your system is corrupted. If not, then make it the default app for the DMG file class.

Quicktime MPEG2 playback broken?

Hello. Suddenly I am not able to watch .mpg files in Quicktime (Macbook Pro) and MPEG Streamclip complains the component is not installed when in fact it is. I ran the installer again, Quicktime MPEG-2 Playback without error. I'm not sure if this problem arose after the QT 7.3.1 update or the last security update. Anyone else?

Purchased Quicktime MPEG2. No audio.

I've just purchased Quicktime MPEG2 playback component for my Mac OS X, and downloaded MPEG Streamclip, and I'm getting no audio from the DVD I imported into imovie. What do I do now?

What content are you trying to play in which application on what operating system? "Muxed" MPEG-2 content imported to iMovie for instance, should now be a MOV file containing all I-frame MPEG-2 video with AC3 audio converted to linear PCM. This file should play in almost any player on the importing system assuming the playing application/system is not muted. On the other hand, "muxed" MPEG-2/AC3 or MPEG-2/PCM content is not normally supported natively by QT (except by Lion and then only in a supported file container) since the MPEG-2 Playback component is a video only codec. MPEG Streamclip should be able to play/demux/convert "muxed" MPEG-2 content and if it doesn't then you may be looking at a more serious or complex problem and will have to provide more information and/or a sample of the problem content for examination/playback comparison on other systems/system configurations.

Apple QT MPEG2 Playback Component conflict w/Mavericks

I am running OX 10.9.1, Mavericks. and wnat to transfer my VOB files from DVD into iMovie for editing. Per the instructions in this discussion (https://discussions.apple.com/docs/DOC-3951 ), I installed MPEG StreamClip. I also purchased the Apple QT MPEG2 PB component - oops! - BC the Apple store says I actually don't need it if I'm running Lion or later. Per the Streamclip site (squared5.com) ,even though Apple says the QT PB tool is not needed, Streamclip still needs it. Fine, whatever. With Streamclip installed, I attempted to install the QT MPEG2 PB tool, but I got this error code: "QuickTime MPEG2 can't be installed on this disk. This software is intended for an earlier version of Mac OSX." For fun, I tried transferring my VOB files from DVD into streamclip, but that yielded another error that teh tranfer would not be complete, adn owuld be missing elements. That's true - the files I transfered to streamclip are now audi only.
So it appears that I need the Apple QT MPEG2 PB tool, but it's not available for Mavericks. Or am I missing something else? If streamclip won't work on MAvericks , is there an alternative QT MPEG2 PB component? Or, can you please show me another way to get my VOB files from DVD into iMovie?
Thank you very much, and I appreciate your time.

I found this info frm samberl in australia (in this discussion thread https://discussions.apple.com/message/17333072#17333072), and it enabled me to install the QT MPEG2 playback component. Although all the instructions are directed toward Lion users, apparently it also applies to Mavericks.
"You need to delve deeper into MPEG Streamclip, Lion and Quicktime MPEG2 playback.
From the MPEG Streaclip website.
"The installer of the MPEG-2 Playback Component may refuse to install the component in Lion. Apple states the component is unnecessary in Lion, however MPEG Streamclip still needs it.
To install the component in Lion, please download MPEG Streamclip 1.9.3b7 beta above; inside the disk image you will find the Utility MPEG2 Component Lion: use it to install the MPEG-2 Playback Component in Lion. The original installer's disk image (QuickTimeMPEG2.dmg) is required.
The current versions of MPEG Streamclip cannot take advantage of the built-in MPEG-2 functionality of Lion. For MPEG-2 files you still need to install the QuickTime MPEG-2 Playback Component, which is not preinstalled in Lion. You don't have to install QuickTime 7."

MPEG2 playback question...

Hi,
Switched over from PC to Mac recently, and playing around with iMovie 8... Planning to upgrade to FCE 4 now.
Question: I notice that I'm unable to play MPEG2 videos that I copied from my PC over to the Mac, although AVI files work ok. Read in a few places that the QT7 Pro s/w addresses this? Do I need to purchase QuickTime Pro in addition to FCE4 to be able to work with MPEG2 files? What other benefit does QT Pro provide that iMovie or FCE 4 don't already do?
Thanks!

You probably need the QuickTime MPEG2 Playback Component. You can get it from the Apple online store ($19.99). You would not necessarily need QT Pro.
When you capture HDV or AVCHD video in Final Cut Express, it transcodes the video into Apple Intermediate Codec during/after capture. So, you're not actually editing MPEG2 when you edit HDV or AVCHD in Final Cut Express, you're editing Apple Intermediate Codec.
If you already have MPEG2 video files, you will need to convert them to DV or Apple Intermediate Codec before you import them into FCE. MPEG Streamclip is a great utility to do the conversion. MPEG Streamclip itself is free, but you will still need the QuickTime MPEG2 Playback Component to convert MPEG2 files.

No sound even with mpeg2 playback component

I purchase the quicktime mpeg2 playback component. Now I see the video, but without audio. How can it be that even paying 20 dollars I can´t see mpeg2 files fine?
Any ideas?
Thank you.

the strange thing is that mpeg streamclip doesn't play the sound neither. May be is a problem with the quicktime playback component?
Make sure it contains audio/what kind of audio by either looking at the "Audio PID" box under the Streamclip "Player" window or the "Show Stream Info" option under the file menu.

Quicktime playback all jerky after update

The last quicktime update has turned my playback all jerky. I can't even play a normal DV cam video with more then about 4 ot 5 fps. The playback info window however doesn't appear to notice and says the playback is fine at 25 fps as it should be.
Since I'm working in the video industry, it is vital for me that quicktime playback. And I work with HDV videos, which have been playing absolutely fine. And now, they play with 1 frame every 3 seconds. I've tried a reinstall of Quicktime, I even completely setup a new system install. Same result.

Please report this
http://www.apple.com/quicktime/feedback
This has happened once before (some time ago) and was fixed. But every one should complain since intel Mac get all of Apple's attention now.
Also, reverting to a previous version with pacifist does work but then you cannot video conference in ichat and who knows what else!

QT 7 update requires Pro + MPeg2 playback purchase?

Hello, I am caught in that awful update quandry - if I now update QT to version 7 and purchase the Pro key, do I also have to purchase AGAIN the MPeg2 playback tool? I have already purchased this TWICE already.
Even though Apple state that the MPeg2 playback tool will work with QT 6 or 7 it doesn't actually answer my question. I can't afford just now to update QT to vers. 7 Pro and find that MPegStreamclip and other MPeg2 dependant software no longer works.
The cost might look puney in America but in Australia we are not so rich and the dollars are double - so having to update Pro and the MPeg2 playback tool is actually quite expensive, particularly when you think how much it cost to buy Tiger and iLife 06 and it is these two actions that have put me in this postion - SPEND SPEND...Ugh, where's the money?

Moving from version 6 to QT 7 requires a new Pro purchase.
The MPEG-2 Playback Component will continue to work if its version number (Get Info) is 6.4. If for some reason you have version 6.3 the update is free.
Move the QuickTime Player Pro 6.5.2 app that you currently own from your Applications folder to your Desktop before you install version 7. This will allow you to run two versions of the Player app on top of the new version 7 frameworks. The older one will remain "Pro". No money spent.

Solution to missing MPEG2 Playback component FOUND!

This solution is for those that have purchased Final Cut Studio HD, and then found the MPEG2 playback component mysteriously missing.
Well, from digging and digging around I found my answer. Check for the existence of /System/Library/QuickTime/QuickTimeMPEG2.component by using command + F (find function). If you find this file, and it's not properly placed in the /System/Library/QuickTime/ folder....then there is the problem. Simply copy and paste that file into the directory mentioned above..
I give credit for the idea to Apple Forums user Dave Jablinsky. Thanks a million!

Please mark this post and the other one you posted on the same subject as solved.

MPEG2 Playback Component gone

Hi Folks-
I have posted this on the Quicktime forum, but thought there might
be more help here.
I have extracted from a DVD using Mac the Ripper (legally-
it's for a client who shot the original footage himself, and
built a DVD out of it). I have then opened MPEG Streamclip
to convert to QT so it can be edited in FCP. However, somehow
I have lost MPEG2 Playback component from QT Pro 7.1.3
(did I lose this when I upgraded from 6?). Am trying to DL from Apple
website, but even as I log in, Apple keeps screwing up my address
info (says I'm in US, when I'm in Canada) and won't let me check out.
A call to Apple and I hear that possibly MPEG2 Playback component
is now not available in Canada (!#@$@#).
Anybody have any experience with this cross border availability issue? Anybody have any suggestions for another workaround?
Did I lose MPEG2 Playback Component just by upgrading to 7.1.3?
(I know other things get lost when upgrading from 6 Pro to 7 Pro, but since MPEG2 Playback Component is an add-on, it didn't occur
to me that it would be lost...
Also- further to the above, I cannot play any m2v files on my box...
Thanks,

[(I know other things get lost when upgrading from 6 Pro to 7 Pro, but since MPEG2 Playback Component is an add-on, it didn't occur

Pretty sure everything from a Pro Key in 6 gets wiped out when going to 7, including add ons such as the MPEG Playback
What software are you running? Final Cut Studio? Playback component is included. Can you roll back your system? (Do you have a pre-QT 7 system back up?)
You can try backtracking your QT install, such as this one -

Mpeg2 playback component for OS 10.3.9. or converting mod files

Hi,
I want to convert mod video files so that I can work with them on the mac. Someone suggestes using mpeg streamclip (which I have, version 1.9.2) and mpeg2 playback component (I have version 6.0.2.)
Unfortunetly, when opening the mod file streamclip asks me to update my mpeg2 playback component. Here comes the problem:
The current Apple MPEG2 PlayBack component seems to be only available for OS Tiger (10.4.9. and higher). I am using OS 10.3.9. and QT Pro 7.1. and I would very much prefer to stay with this setting.
1) Does anyone know where I could get an older version of the mpeg2 playback component?
2) Or, is there an alternative way, instead of using the mpeg2 playback with quicktime to convert the videos into something iMovie (I have iM 4) or another programm can work with?
I found this website, would that be of any help? http://www.modconverterformac.net/
3) Which other program (thirdparty) besides iMovie could I use to cut and view the videos on the mac? I have Final Cut Pro, but it is too complicated for me.
Thank you very much,
Janik

hey niel- i have as question that u might be able to help me with

can u help me cause im a pc user and im confused thx!

MPEG2 Playback Quality

Hello,
I'm trying to use the MPEG2 Playback component to extract some VOB files from DVDs files for editing in iMovie. However, the files always come out with a jitter in them when there's a lot of movement on the screen. It's particularly noticable during title sequences or long pans.
I've tried converting using MPEG Streamclip and QuickTime Pro with several different codecs with many different settings on two machines and they all exhibit the artifact.
Is there something that I'm missing with regard to converting from MPEG-2? Do I need to get a higher end video system such as Final Cut Pro? Am I smoking something and overlooking something stupid (most likely)? Any advice would be greatly appreciated.
I don't think it's performance based, I'm using a dual 2Ghz PowerMac.
Adam Ruth

Your source files (MPEG-2 from the DVD format) may be the cause.
The export and conversion can only use what it finds to work with and export to other compressions schemes (.mov or .mp4, etc.).
Have you tried exporting to DV Stream? This should keep the quality of the MPEG-2 file very similar to the source.
Since iMovie is a DV editing app it only makes sense to export to something it uses natively.
Exporting to other formats and then reintroducing the file to iMovie will convert your file. You don't want that to happen.

MPEG2-Playback for QT and new Intel Macs

Hi! You can update the component to 6.4.1 or you can
force QuickTime to run in Rosetta so that it can
(try) to use the PowerPC version of the component
that you already have.

Bought QuickTime MPEG2 component - "installed" but it's not there

I just bought the MGEG2 component and ran the installer - it said it was going on my hard drive, ran the progress bars, etc., and even gave a nice cheery "installaiton Successful" announcement with an attractive green check mark, Too bad it didn't do jack for QT's ability to open files.
When I look in my (hard drive)/Library/QuickTime/ directory, it's not there.
It should have a resource filenamed "QuickTime MPEG2.component" (everything there is for audio (AC3), Div6, Perian, Flip4Mac and the Save as AVI component from MPEG Streamclip.)
Antbody understand why it's not where it should be?
Reference info:
OS 10.6.7
QT Pro 7.6.6
MacBookPro (Intel 2 GHz)
component installer v. 7.6
(creation date Jan 14, 2009) <- too old?

1) What part of their MP4 doesn't my version of QuickTime understand? (It reads a lot of mpeg-4s, what does it need to know?)
You have two different facets here.
The first is MPEG-4/AVC (H.264) video multiplexed with AC3 audio wrapped in an M2TS, MPG, or MPEG file container. This has many problems. On the one hand the video is MPEG-4 and so the QT MPEG-2 Playback component cannot decode it but it is wrapped in an file container that is basically telling QT to use the QT MPEG-2 Playback component for video playback (i.e., much the same as why VLC considers the content MPEG-1/2 data because that is what both media players expect even though VLC can actually handle the audio and video data in this wrapper). On the other, QT is not natively compatible with AC3 audio and cannot play it natively even if it was able to "demux" the blocks of audio and video data properly and synchronize the two to a common external time reference which is the basis for QT media technology. (I.e., The wrapper being used is based on spatial synchronization of audio and video data interspersed in a single data stream rather than the temporal synchronization of up to 99 parallel data tracks normally used by QT—a basic difference in player technology akin to trying to play a BD disc in a CD player.) Normally, the way around this problem is to use iMovie '08, '09, or '11 to import your content. iMovie contains a special import/converter module to handle this content. Basically, it converts the AVCHD video to AIC (Apple Intermediate Codec), converts the AC3 audio to resampled linear PCM (AIFF) and applies timing offsets as may be needed to ensure synchronization between audio and video content. This data is then wrapped in the generic QT MOV file container making the files compatible with any/all QT based applications. Unfortunately, the special module cannot be used by files already imported to your hard drive at the "Finder" file level.
As to MP4 (SD MPEG-4, Chapter 2) content, these files may or may not be compatible with QT depending on how the audio is encoded, the file container actually used, and/or how your system is actually configured with QT components. In most cases, making the content compatible may be as easy as doing nothing, to changing the file extension or copying the data to a real MOV file container to using MPEG Streamclip to convert/handle the audio content.
2) Why does VLC show the file properties as MPEG-1/2?
Like QT, when VLC sees the wrapper file extension, it "assumes" the file contains a specific type (or range) of data types and reports accordingly. The main difference here, is that VLC can actually play the AVCHD data natively while QT cannot.
By the way the MPEG-2 description jived with a review - CNET, I think - which I'd read online. No doubt this will provoke another one of those explanations that always boil down to "you don't understand, the wrapper isn't telling you what's in the files" responses. Is there a tool for telling what the thing actually is?
Interpretations can sometimes be confusing. HDV content can also be described or reported as MPEG-1/2 content since it is sometimes described as DV100 encoded data wrapped in an MPEG-2 file container. As to what is actually in a file container and utilities to read them, there are a number of such available as free downloads. Unfortunately, many will have the same problem with MPEG/MPG containers if they bother to read them at all but do really well with other file containers. Since most of the content I deal with is MOV, MP4, and/or M4V, I tend to use the free VideSpec and/or Dumpster utilities. In my case I am more worried about MPEG-4 Profiles and Levels, entropy encoding modes, fourCC identifications, key frame frequency, key frame data rates, how the data is distributed between key frames, and the like when trouble shooting problems and most of my dealings with AVCHD are limited to the conversion of DVR/BD content to TV2 compatible content since I don't even own an AVCHD camcorder (and still prefer HDV for editing purposes).
The broader question remains - is QuickTime meant to be general purpose, at least as a player?
No, it isn't. As previously stated, QT technology is based on temporal synchronization of multiple parallel data tracks (up to 99) to a common reference clock and not spatial synchronization by interspersing of blocks of data within a single stream or the interleaving of data frames (which QT can handle because the data is only out of sync by one half-frame per n-1 tracks). This is great if you mask, layer, window, etc. content within a single player but severely limits QT compatibility with older and/or currently competing technologies. In short, pick your player/converter based on the technology used in the source file and not because you think QT should be an all purpose, one size fits all multimedia utility. If FLV Crunch meets your needs, then by all means use it.
I took some similar files I got from a recent model Canon to a video professional's (family) and they couldn't be read by a current version of FinalCut Pro.
Which model Canon? Which "current" version of FCP, the suite or the new FCP X release? Do you have a short snippet you can upload for examination? Have yet to research the pros and cons of the latest release but plan to do so next month if/when I have the time. (I.e., users seem to either really love it or really hate it.)
PC video straightforward, Mac a colossal hassle until you find the right 3rd party application: does that sound wrong to anybody else?
If you opt to use an import work flow that preserves the QT file incompatibilities instead of a work flow that ensures QT playback, conversion, and editing compatibilities, is it the fault of the software or the user?
