Problems with MPEG2 - Quicktime

Hi!
I just bought both the Pro Version plus the MPEG Plugin. I am using MPEG Streamclip to convert a DVD (without CSS) to Quicktime.
I got the following problems:
1)
On long movies, the singles parts are all detected, but Streamclip only show half the length of the time. When I forward the video inside Streamclip I can see that the full movie is there and that only the time is devided by 2.
But the result then only got the first half off the movie
2)
On short videos (like a TV Series Episode) the converted process often crashes at around 95%
3)
The time to export into Quicktime is very long. I got a 3,2GHz Single Core P4 with 1GB Ram, but a 45min DVD Recording takes around 6-8 hours to be converted into quicktime. Is this normal???
Looking forward to any help or questions if more information to help is needed!
Martin

The QuickTime MPEG2 Component comes with an installer. Did the installer run? Did it show any errors?
It is working for me in QuickTime on Windows XP.
Note: Even with this component there are some limitations. It cannot play AC3 sound tracks. It should however be able to play MPEG2 video from .m2v or .vob or .mpg files.

Problems with a QuickTime movie file. Error 2048 message

I am having problems with a QuickTime file.
The file is on a TDK 4GB pen drive.
I can access the file without problem directly from the pen drive.
I am using a Sony VAIO Laptop running Windows 7.
QuickTime version 7.71.80.42.
When I transfer the file to a folder or upload to send via e-mail on Hotmail and then try to open it I receive an Error 2048 message - "Couldn't open the file.......because it is not a file that QuickTime understands.
Any help would be appreciated.

You should be fine: a standard DVD can contain up to 120 minutes of video, but this includes menus etc.
iDVD is not concerned with file sizes, just length. It will automatically compress the iMovie file to the standard DVD format of mpeg2 - which is 4.7GB for 120 minutes!
I have once made a family DVD 115 minutes long, but after the family either protested or fell asleep, I have tried to keep them under 75 minutes!

Isolating problems with MPEG2 VBR "best"

There have long been discussions here around problems with the quality of MPEG2 compression with Compressor v2.x, usually difficult to quantify or "solved" with "It doesn't work, use something else" such as a different product, Compressor v1 or a Quicktime MPEG2 export component. Maybe I'm an optimist, but I have to believe that someone who owns the code behind the Compressor product really does care to improve the quality of the compression, and is just waiting for a decent test case to figure-out what everyone is complaining about.
That in mind, I would like to propose that the most visible problems I've seen can be isolated to something to do with what is done when switching from "VBR" compression to "VBR best" compression, either in 1-pass or 2-pass mode. I would be curious if others who have had similar quality complaints could also check if they are using "VBR best" compression, such as the various default presets for "DVD: MPEG2 best quality..." which use "2-pass VBR best". In short, it seems as though one can get rid of the most serious artifacting problems by taking a "best quality" preset and changing the quality from "2-pass VBR best" to simply "2-pass VBR" (and similarly for 1-pass).
My own example: I've taken a short clip (less than 30 seconds) from the start of a recent home movie and published it along with some results on my iDisk's Public folder (Finder > Go > iDisk...): member name "dickermn" [sic], with no password. There you will find the folder CompressorTest, containing...
-> 2006winter - a self-contained QT movie with the DV source material.
-> dualG4 - a folder with the results of Compressor's MPEG2 compression with various settings, as run on a dual-1GHz G4 system.
-> coreDuo - a folder with the results of the same settings as above, but with Compressor run from a coreDuo mini.
-> *.png - two pairs of window-capture shots showing the same frames as compressed with "VBR" and "VBR best" settings.
Background: after having various odd and intermittent problems with MPEG2 compression results, I've used the recent upgrades to start with a clean slate: on the G4 system I ran Software Update, then removed all the components of DVD Studio Pro 4, Compressor and Qmaster, along with all preferences, application support files, frameworks, receipts, etc, as recommended in these web pages to remove these programs, then did a full install of my unversal upgrade to Final Cut Studio, and re-ran Software Update. This got me up to the current ProApps updates and Compressor v2.3.
Using only Compressor's default presets, selecting "DVD: Best Quality 150 minutes - 4:3" (2-pass VBR best, 3.7Mbps average rate), gives results with very visible artifacting. Using this same preset but changing the quality to "2-pass VBR" appears to clear up the most visible problems. Similarly, selecting "DVD: Fastest Encode 150 minutes - 4:3" (1-pass VBR) gives good results, but changing the preset's quality to "1-pass VBR best") produces visible artifacting.
For the purposes of testing, I also installed just Compressor on my coreDuo mini - a clean install - then ran Software Update to bring this to Compressor v2.3. Running the same tests as above on the Intel-based machine produced similar artifacting problems when selecting "best quality", but in different places in the media than on the G4. Using the same quality settings as above, but moving the average bitrate down to 3.0Mbps has similar behavior, but the artifacts are just more pronounced, and using a default preset with higher bitrate (5Mbps average, not included here) the artifacts are still quite visible, but less pronounced. From the 3Mbps results on the G4, the still frames captured show good examples of the problems at hand, though the artifacts are much more visible with the video in motion. These are the examples described below.
The clip shows some still titles against a still, horizontal-blurred background. At the end of the titles, the blurred background "un-blurs" and the motion starts: a horizontal pan, a wipe transition, and a downward pan. The subject is all falling snow, trees, our back deck, my son and me. The footage was taken with a consumer-grade Sony handheld camcorder.
The problems first noticable in the video appear as a blockiness to the images, particularly notable against the floor of snow where the image shifts visibly to different intensities of gray/white as the camera moves. More severe are blocks which don't move correctly with the camera, at first visible as a jerkiness to the opening background as it un-blurs, but more pronounced in the trees and decking during the downward pan at the end.
At about 14s is a good still of the blocking artifacts, seen here in the 1-pass VBR still frame. Note the large blocks in the snow in the "best" encoding, which are small enough to be lost in the noise for the "not-best" encoding. These shimmer between the different shades of gray as the camera moves.
At the last half of the clip, as the camera pans down, parts of the trees appear to jump independently of their branches. This is very clearly visible around the straight-lines of the railing in the lower part of the frame as the clip ends. The still is from about 23s into the clip, and you can see a block of the railing in the lower right which has clearly jumped-above the rest of the railing. Interestingly enough, this is the correct placement for those pixels in the next frame (as the camera continues to pan downward). In each of these "jumpy" cases, it would appear as though blocks of pixels show-up one frame early, and their surrounding blocks catch-up in the next frame (while these hold still). Again, when using the same settings without "best" quality, the jumping does not occur.
Note that with each pair of still (png) images you can group-select the pair and double-click to open them both in Preview, which allows you to toggle back-and-forth easily between the "best" and "not-best" versions. Comparing the two, you can easily spot several blocks in the frame which shift relative to their surroundings.
While I am aware that MPEG2 at low bitrates is a complicated thing (though I will leave open for debate how low 3-4Mbps is in today's world), and consumer-grade video has lots of noise which the encoder has to dance-around, I do believe it is fair to assume that the "best" settings should give visibly better results than their faster "non-best" counterparts, all else being equal - at the very least, the results should not be visibly worse. It is worth noting that the "best" VBR settings do appear (subjectively) to give better contrast or color-depth, so clearly something right is going-on - I just have to believe that there is something going awry in the whole process which creates artifacts negating the other benefits, but which, with any luck, could easily be fixed.
Please post with your comments, experiences or similar issues... or exactly what is the proper way to get this information to someone who could fix it?
dual 1GHz G4 + coreDuo mini Mac OS X (10.4.8) Compressor v2.3 / Final Cut Studio (univseral)

Well, I've found one more piece to this puzzle: hardware graphics accelerators.
In short, I tried this same test running Compressor on my G4 PowerBook (with Radion Mobility 9700) and got better results. The terrible blockiness and pixelation problems seem - dare I say it - gone from the MPEG2 video. In this regard, the video compressed as both the default "2-pass VBR best" and the same preset adjusted to use "1-pass VBR best" both looked cleaner than any of the VBR "not best" encodings produced on this machine, or either of the others.
Unfortunately, we're not completely out of the woods: the problems evidenced later in the clip - blocks which appear displaced in space/time for one frame - are still there, though they have moved to different locations in the frame.
This gets me to thinking: my PowerBook is just barely past current muster in terms of hardware-accelerated graphics (enough to run Motion, for example), whereas my other two machines are not (NVidia GForce4Ti & mini's Intel graphics). So this starts to get to the root of "If these presets don't work, why does Apple label them best - or distribute them at all?" I'm going to hazard a guess that there are various pieces to the codecs which can take either a software-only path or a hardware-accelerated path, and the bugs seen here exist only in the software (non-accelerated) path. Anyone testing on the latest top-notch hardware with a fancy-shmancy graphics card wouldn't go down that path and see any problems. And the problems are subtle enough that they'd even slip by the occasional testing of the slower path.
So now I'm out to find a more-current-than-my-PB graphics card to run the test, to see if I can get rid of the other problem. Updating to Compressor v2.3 got rid of most of the problems, and if buying new hardware is all it takes to fix MPEG2 compression, I might just spring for it - and hey, I'd get to run Motion, too.
So anyone out there with a whiz-bang graphics card care to run these tests and compare/contrast with what I've got here? I might know someone with a new MacBookPro, which I hear has a pretty current graphics chip in it...

Problems with Mpeg2 using CS5

Hi there
I am having problems with Mpeg2s.
The sequence preset is HDV 1080i25 (50i) and exported at 1440x1080i 25 High Quality.
When I encode my video and play it back on Windows Media Player or Realplayer at certain points the sound crackles and then a couple of frames jump. I have encoded it a few times and it often happens around the same place each time. If I only encode a certain section of it the jump still occurs but at a different point. Sometimes it happens more than at others.
I encoded enough instances of the video to stitch it back together on a new sequence and encode that without any of the jumps. When I imported all of the mpeg2s on to the sequence to do this the jumping wasn't happening at all when played out on Premiere Pro. Also it doesn't happen as obviously when played in Nero.
So basically I would like to know why there is only a problem when I play the Mpeg2s in Windows Media Player and Realplayer but not when I play them within a project in Premiere Pro CS5? Is it a problem that can be fixed in Premiere Pro or whether it is a problem with Windows and Realplayer?
It is all seriously puzzling to me. I will appreciate any help directed my way, I have seen this problem on other forums but no-one seems to have an answer.
Cheers.

I agree with Jim. Many experience similar issues in WMP, and I did not know that RealPlayer was still around.
I use VLC, or MediaPlayer Classic HC (both free), and find them much better than WMP, in almost all respects. There is a similar thread in the CS4 sub-forum, and it seems that WMP is the big culprit there.
Good luck, and let us know if VLC, GOM or MediaPlayer Classic HC do better jobs, playing the files.

Two new problems with the Quicktime Plug-in

I recently discovered two new problems with the current Quicktime Plug-in for Mac OS X.
First, the Quicktime Plug-in is unable to stream Quicktime media in any internet browsers other than Safari.
There is just nothing on the spot where the embedded Quicktime player should be.
Second, the Quicktime Plug-in only shows the message "The operation couldn't be completed. This file is not a movie file (-2048)"
everytime it should work together with the Flip4Mac Plug-in. The thing is, when facing a webpage where a wmv or wma file is
embedded, there only shows that error message on the spot where the player should exist. I first thought that it would be a
problem with Flip4Mac. So I uploaded about this problem on telestream.net, only to hear that the error message above belongs
to the Quicktime Plug-in.
Both of these problems did not happen at all only three weeks ago. The embedded Quicktime player showed up without any problem
in my Firefox and Opera, and wmv or wma files were streamed successfully through the Flip4Mac and Quicktime Plug-ins.
Then, suddenly, after some point, these two problems began to occur, and there is no information on how to solve them on the web.
I obviously tried uninstalling and reinstalling Quicktime. I even completely erased the hard disk of my Macbook, and reinstalled the
whole Mac OS X. But the problems still remained. I borrowed another Macbook from my friend to check whether these problems
occur in other computers, and they did occur in my friend's Macbook as well. So they are definitely not the matter of my own Macbook only.
I think these might be the problems with the new Quicktime Plug-in 7.7.1.
Please check about these problems and solve them on the next version of the Quicktime Plug-in.
I will give you a couple of hyperlinks so that you can check about the problems directly.

Import Problem with FCP quicktime file.

Hi,
I exported my 18 minute video with FCP quicktime (instead of quicktime conversion I did export quicktime video in FCP). When I try to add this video to DVD Studio Pro, The first thirty seconds of video import and all the sound imports but no video imports after that first 30 seconds.
Does anybody have any idea what this is?
Thanks!

Sounds like a corrupt file. You should try opening it in QT and then saving it out with a different name if it works OK there. Be sure to make a self contained file, not a reference file.
However, you may find it better to export from FCP through to Compressor and create your MPEG2 files there before bringing them in to DVDSP. This is a better work flow for lots of reasons, ensures you use a dedicated encoder and releases DVDSP to concentrate on what it does best (which certainly isn't the encoding, IMO!)

Problem with iWeb Quicktime page using Boot Camp Windows XP

I used iWeb '08 to create a one-page web site with a short QuickTime movie (.mov file). The movie plays fine in Mac OS X Safari. I have a Windows XP Boot Camp partition, and when I boot into Windows and load the web page using Internet Explorer, the movie will not play. It gives a plug-in error and the browser crashes. The same thing happens with Windows Safari. However, the movie plays fine using Windows Firefox.
Is this an iWeb problem or Boot Camp problem? I don't have access to a straight Windows PC. An suggestions will be appreciated. The URL for the web page is:

The problem was a setting in QuickTime. I enabled "Safe Mode" in the Advanced tab of QuickTime Preferences, which did the trick.

Problem with iTunes/QuickTime

I just got an iPod and went to go download iTunes. I installed it, and it won't start. It says it "encountered a problem and needs to close" It invariably does this every time I start it, and quicktime does the same thing now. I can't even get into the quicktime settings on the control panel.
I have un-installed, re-installed, and updated in every known combination for several hours over the past two days, so I would greatly appreciate any help.

+It invariably does this every time I start it, and quicktime does the same thing now. I can't even get into the quicktime settings on the control panel.+

That can give us a specific heads up on certain problems (in particular, if the issue is with a codec pack or other program that has also installed "QuickTime" componentry on the PC).

Premiere Pro CS4 - Problems with mpeg2 export file

Hello!
I shoud get export a one videofile (mpeg2 D-10, 4:2:2) with 4 audio channels (two stereo track). Audio must be .wav and PCM. The end result shoud be on channel 1 and 2, which has music, effects and narration. Channels 3 and 4, everything else, but without narration. (tv company wants to change narration language).
The problem is that Premiere Pro cs4 connects two separate stereo tracks to one stereo track when I export mpeg2 file. Another problem is that Premiere Pro does not accept PCM audio if I have any multiplexing setting selected. If I select none multiplexing, audio is seperate from the video file.
I have now about 150 test clips with different settings, nothing works...So, please help me! What shoud I do? Is this possible with Premiere Pro CS4 and Adobe Media Encoder? If so, how it can be done?

I don't believe the end result is possible with Premiere Pro alone. You'll have to export out am .m2v file, and two separate .wav files. Then look to other tools to mux them together.

What's the problem with MPEG2?

Hi all!
What problem does Apple have with the MPEG2 format?
I mean, look at the new ads "hi I'm a Mac, hi I'm a PC" -- Apple claims to be THE hard & software platform for the modern media life.
Applications like iPhoto, iMovie, iDVD, iTunes are great, true! I love 'em.
But hello? Is Apple sleeping? Everybody nowadays records his/her favourite TV show via a TiVo or any other DVB-T, DVB-S or DVB-C hardware directly on the harddisk. And this is MPEG2.
Now does Apple really want me to convert my 34 minutes (828MB) MPEG2 into DV format just to please iDVD if I want to make a Video-DVD with three or four of these shows?
828MB converted to DV format lets the size explode to over 7GB(!) -- just to let iDVD convert it back into MPEG2 when it burns the final DVD!
This is crazy!
Or am I missing something?
I have Final Cut Studio Pro installed but still, iDVD doesn't accept MPEG2 files.
(Using DVD Studio Pro is not an option here because I want to show my girlfriend how to use iDVD so that she can burn her own DVDs with her favourite shows, and she just has iLife '06 on her PowerBook.)
Any suggestions?
Thanks,
Stefan.

Tag Stefan,
I totally agree...- there's allways room for improvement, software should follow the needs of the market...
but, as mentioned often:
mpeg2 is a delivery format, not meant for further processing.
And, you "Lieblings" company doesn't support second choice in quality...
out-of-the-box, a Mac does NOT support usage of mpeg2 (as no PC allows that...)...
there are lots of ways to handle that, Apple mpeg2 plugin (20$) + Streamclip allow converting and some basic mpeg2-editing (getting rid of ads, or instance)… Sizzle is a free tool to create DVDs from mpeg2s... VisualHub is such another tool....
PCs are more sold, therefore more apps, more "friends" offering "to share" apps....
handling of mpeg2 in iM IS supported, but just by importing it from a HDcamcorder into iM... then, the app converts it into AppleLosslessCodec… time consuming process, a big überMac needed....
… so all parts are there, theoratically, Apple just has to stick part I to part II to offer an import of external mpeg files into iApps..
iM7?
Grüße nach Bonn....

(Audio) problems with MPEG2 content

Hi everybody,
I have the following problems:
I have 2 movies, MPEG 2 format. I bought the Apple MPEG-2 component for Quick Time, the movies play fine. Then I trimmed them using Quick Time X and saved them as a "film", i.e. not changing any contents (at least this is what the menu information says).
1st problem: The movies still play fine, but strangely have the same file size as the source. How is this possible, if I have trimmed them (I actually cut both of them in half)? Info says the codec of the trimmed movies is "m2s", while the codec of the source files is "MPEG Layer 2, MPEG-2 Video".
Then I assembled a DVD using iDVD 7.0.4. When previewing the project in iDVD, everything seemed fine. I then saved the project as an image file.
2nd problem: When previewing the image file with DVD player, there is no audio. The image quality is fine, but no sound at all.
3rd problem: The iDVD .dvdproj file I created the image from is suddenly bigger than 5 GB, which is roughly the size of the image I created. Also, I can't open the project file anymore without causing iDVD to hang at startup.
Does anybody have a clue what is going on? Any help is highly appreciated!
Thank you!!

No, every codec is compressed. But it is a question of how much, and in what manner. Some codecs compress each frame in the same way image files are compressed (intraframe compression). Some codecs also use incomplete information for the frames, relying on prior frames for some information (interframe compression). Codecs with interframe compression save space, but are not good for editing because your software has to recreate a complete frame when you are creating an edit point, which takes extra time. So different codecs have been devised to fill different needs and applications.
Mpeg2 is done in such a way that it is space efficient and high quality, but introduces enough artifacts that once you transcode to mpeg2, you are better off going back to your source if you ever need to edit again.
There is uncompressed video, but I would call that a format rather than codec (compressor/decompressor). If you converted your footage to uncompressed, it would take up somewhere around 100GB for each hour. DV only uses 12GB per hour.

Problem with installing quicktime

Ok I downloaded quicktime for windows and installed it but when it gets to the end of installation it reboots my pc and doesn't finish the install. And when I log back in I get the message from windows that there was a serious error or w/e. And it shows the quicktime icon but when I double click it shows this error "QuickTime failed to initialize. Error # -2095 check to make sure Quicktime is installed properly on this computer" I tried reinstalling twice and each time it does the same thing. anybody know why?

I am also having these same problems. I have downloaded Quicktime numerous times and get then when I go to start-up iTunes get an error msg that I need to install Quicktime !!?? I am using XP OS. Also wondering if a re-intstall of iTunes will mean that I would lose all stored music files?
