No audio in Mpeg2 file.

I have three avi files from a parade. When I export them to adobe media encoder, the audio only works on one file. I use these settings:
4:3
Lower Interlaced
CBR with PCM audio (8mbps with the 25 minute file (the only one that works) and 4mbps with the 60 minute avi file and the 55 minute avi file (neither end up with audio intact).
Set the multiplexing to DVD.
I have used these settings many many times and they have worked great...but not this time.
Any advice would be appreciated.

MPEG Streamclip has no option at all for MPEG2 output...
In case, I didn't give enough information:
I have Quicktime Files (and other file types).
Need to Create MPEG2 Transport Files that have AC3 Audio.
Compressor Can do MPEG2 TS Files but won't let me change audio from mpg to AC3.
StreamClip Can read QT Files but cannot export MPEG2 Files at all.
HandBrake Can Read MP4 Files but cannot export MPEG2 Files at all.
Trying Episode Encoder Trial to see if it does it.

QT won't play back audio with MPEG2 files

I've upgraded to Pro and have added the MPEG2 plugin. QT plays the video fine, but I don't get audio. Have checked the files with another application (VLC) and the files play fine. I've using files from a new Sony hard disk digital camera. Anyone have an idea as to what the problem may be?
Thanks,
--Mike

I've upgraded to Pro and have added the MPEG2 plugin. QT plays the video fine, but I don't get audio.
Since you did not specify your particular "playback" work flow here, it is difficult to determine your specific problem. (I.e., did you drag and drop the file to an application that would automatically attempt a "transcoding" of the material which the MPEG-2 component cannot handle.) Then too, the Sony MPEG VX format in itself is proprietary and the technical specifications do not appear to have been pubished for general public consumption. (I.e., we don't know the specifics of the format. For instance, is it an AC3 audio format, was it VRB encoded, etc.) See MPEG-2 FAQs
However, since you already have the MPEG-2 component installed, have you tried playback/conversion in an application like MPEG Streamclip? It may allow you to convert the file to DV for editing or directly to other QT/iPod compatible formats with audio if no editing is required/desired.

Error code -2048 while opening a MPEG2 file

Probably a straigth forward question.
I have captured some HI8 video in various MPEG formats using a Pinnacle Movie Studio Box with Windows. I can import MPEG1 file to my new IMAC G5 however while trying to open a MPEG2 file (which open with RealPlayer on Windows) I get the Quick Time "error -2048 : the file is not a movie file".
Do I need to install QuickTime MPEG-2 Playback Component?

Don't waste your time! I installed the MPEG-2 Component and now Quicktime will "play" the movie but freezes after the first frame. The audio plays; the video just sits there.
This forum is full of people with the same issue, which Apple has not addressed.
It freezes despite having the Pro version, and the latest system and Quicktime.
If you find a solution, let us all know!
The MPEG-2 Playback Component is required.
To further edit the files (and retain the audio)
you'll need additional software.
MPEG Streamclip (free) can convert your MPEG-2 file
to DV Stream that can then be edited in iMovie (and
any other DV editing software).

Can Compressor make MPEG2 files that will work on a Princeton Video server?

I am responsible for selection of equipment and software for the local Public Access studio. I am trying to be sure if Final Cut Studio will output the format we need.
We need to output video files that are compatible with our Princeton Server Group B1400 Digital Video Server. We have found it is very difficult to be certain if a particular program will generate what we need. Below are the specs for our server.
Basically it is a a rather specific form of MPEG2. I see on the Apple web site that Compressor will do MPEG2, but that is qualified with "Quicktime", and is mostly described as being for DVD production. It seems that those are not necessarily compatible with our server. It wants a plain MPEG2 file in the format given in the specs. The server is a Linux system and its software does not know about special formats like say Quicktime or DVD might wrap around the basic data. It seems to want just plain files of MPEG2 video (and audio of course) data.
One of my sources of my concern is that in spite of what Apple says about Compressor doing MPEG2, the makers of the server say FCP does not create output for it.
I need to be assured about this before we invest in software and possibly new hardware.
These are the specs for the encoding the server needs:
Princeton Server Group
B1400 Digital Video Server
Encoding Requirements
In order to ensure optimum video playout quality on the B1400 Digital Video Broadcast Server, MPEG video and audio content must be encoded as follows.
• Video files for play-out must be encoded in multiplexed MPEG-2 program stream (PS) or MPEG-1 system stream format. Video can be encoded at rates up to 15 Mb/s.
• Use 4:2:0, not 4:2:2 encoding.
• Audio must be encoded as MPEG1 Layer II, AC-3 Stereo, or Linear PCM.
• The video and audio presentation time stamp (PTS) values in a file must be continuous and increasing. The time between the first and last time stamps in a file should reflect the actual duration of the file.
Encoding Recommendations
• Resolution: 720 X 480 or 704 X 480 in NTSC
• Closed GOP (Group of Pictures) with an “I-frame” every 15 frames
• Audio bit rate of 256 kbps
• Sampling rate of 48 kHz
• Program stream files should have one end code (00 00 01 b9) at the very end of the file.
• Recommended bit rates for various types of video content are as follows:
o 4 Mbps for good quality video with low motion
o 6 Mbps for good quality with average motion
o 8 Mbps for good quality with high motion and
o 10 Mbps for high quality with high motion content.
• MPEG2 files are constructed from multiplexed audio and video streams. The length of video and audio stream segments within the MPEG file should be identical.

Hey Terry
in the corporate world wee have to contend with clients who are all windows based and prevented from installing anything on their systems.
I use Flip4Mac, Studio Pro HD, with the following mix of settings;
Open clip in QT, I do also use compressor but for some reason I like using QT for exporting to WMV.
File/Export
Export:movie to windows media
Use: One pass VBR, Presentation (high), 16:9
Options>
Advanced... input type: interlace Lower field first(DV), output type: progressive
Coding method: Two pass VBR
Give this a shot and then tweak to suit your needs, oh and you can save your settings as a preset for QuickTime.
Within Compressor there is no export to WMV, so you have to start with another setting and create your own saving it for future use.

How To Use mpeg2 Files ?

I have used TiVo Decode Manager for years to transfer files from my TiVo unit to my computer. I've always transfered into the mp4 format, for use in iTunes and on my iPod. I just noticed an option to transfer into the mpeg2 format, which I understand is used for compression on DVD's. I can't seem to import the mpeg2 file into iDVD, and when burned to disc, the raw file plays audio but not video on my stand-alone DVD player. How might I use the mpeg2 file in iDVD to create a finished DVD? Thanks for any help.

DVDSP and Toast Support adding Mpeg-2 files but unfortunately iDvd will not. Per the following KB article from apple's web site:
You can’t add MPEG-1 or MPEG-2 files to an iDVD project because they don’t contain standard video tracks.
http://docs.info.apple.com/article.html?path=iDVD/7.0/en/6655.html
But you can use Toast. The Help Menu within Toast 9 states the following:
You can add any QuickTime-supported video files, such as DV, AVI,
MOV, HDV (1080i/720p), and MPEG-4. You can also add files that
QuickTime doesn’t support such as iMovie HD projects, MPEG-2,
DivX, Eye-TV recorded shows, and TiVoToGoTM transfers.
And of course Apple's DVDSP offers native support of Mpeg-2 but it's much more expensive and takes significantly longer to learn than the other option/s offered above.
Other viable options include Visual Hub and MpegStreamclip (free download):
OVERVIEW OF MPEG STREAMCLIP
MPEG Streamclip is a converter, an exporter, a player, an editor, a downloader.
It can open many file formats: muxed files MPEG, MPG, VOB, PS, M2P, MOD, VRO, DAT, DCM, VDR, PVR; transport streams TS, M2T, MTS, MMV, REC, VID, AUD, AVR, TP, TP0, TRP, TOD; demuxed files M2V, M1V, MPV, AIFF, AIF, M1A, MP2, MPA, AC3; QuickTime-compatible files MOV, DV, AVI, MP4, DIVX, WMV, FLV; pictures TIFF, JPEG.
MPEG Streamclip supports MPEG-1 video, MPEG layer 1/2 audio, AC3/A52 audio and PCM audio. MPEG-2 video is supported in conversions, but for playback and export you have to buy the MPEG-2 Playback Component ($19.99) from Apple.
To open DivX files, you have to install one of the free DivX-compatible codecs (DivX 5 or 6, 3ivx, XviD).
To open WMV files, you can install the free Flip4Mac WMV Player from http://www.flip4mac.com/ . Export to WMV is supported if you buy Flip4Mac WMV Studio.
To open FLV files you have to install Perian, a free codec pack, from http://www.perian.org/. But note that currently, Perian does not "obsolete" or replace other codecs so you still have to install 3ivx, DivX, XviD when required.
Hope this helps but if not just come on back.

No recognized audio in .M2TS files

I've seen a couple of different threads about this issue that have said the same thing but all have referenced AVCHD from various Sony Cameras. In my case my footage is from HDPVR. Why the capture device would matter doesn't make any sense to me but regardless Premiere Pro CS6 doesn't just not import the audio... it doesn't recognize it at all. There is no mention of audio at all when looking at the properties.
My footage is recorded with AC3 (2 channel source)
As everyone else has said... there was no issue with 5.5 which is what I'm still using to edit since this is obviously broken in CS6.
I've yet to see a concrete solution anywhere. I was hopeful that a bug fix would be included in the update today but no such luck.
So what's the solution Adobe? Is there a bugfix coming? In the mean time I should just leave CS6 installed in hopes of an update to fix the issue?
Slightly Annoyed with this.

OK OK OK ! Everyone is rigth . Here we´re wrong. Hitachi corporation is wrong, makiing the hayabusa´s camera that produces a MPEG2 file that CS6 "hate" ! The 40K dollars Sony camera we have , make a .MPEG file that CS6 "hate" , and yet these two companies decided to use non-standard file on purpose, so that users had problems many problems, to cause, delays, losses, hassles and all sorts of trouble with clients, losses contracts . miss schedules and so on. A jerky and flaw Encore to do not generate the DVDs, many PGC problems, and so on. OK.
OK. ADOBE is that it must be right, and the whole world wrong. Thank you. I know well what we here suffer with this CS6, and user Hayabusa knows what he is passing trough his CS6 do not recognises audio. The CS6 he have installed in his machine maybe other tha "hates" his audio files.Tje software "hates" us is the only explanations.
We do not try to use CS6 anymore. We knew what we being trough. many monts of sadness, frustrations, many many many redo jobs...
Maybe in the future a new version CS7 will solve problems and return with MPEG2 fully supported, as occurs today in CS5.5.
An editor who works here, once said, that seems to be "The curse of the even number"! Explaining : The CS3 version was very good. The CS4 came full of problems and unstable, as occurs today with CS6. The CS5.5 came and solved the problems of CS4.
Thus, the CS7 will come OK, no problems and everything is working to solve the problems of CS6 !

CS6 encoder no audio in mpeg2 dolby

No Dolby audio with encode mpeg2 files,
Adobe Media encoder updated 6.0.1.31(64 bit),download upgrade from cs5 and,not cloud,is not properly encoding MPEG2 with Dolby digital set at the audio tab.
The rendered mpg file shows no audio at windows right click file properties details,yet and curious, there is audio if I play the the file in windows media player in the computer the file was created (the one premiere cs6 is installed, but the same file from portable HD´s in other PC´s , ps3 or media players like asus plays with no sounds.
I like to have all my projects rendered and saved to mpeg 2 1920x1080 with audio Dolby digital 256kbps,(this way they go without transcoding in encore if I need a BD disc), but I prefer to have them stored and viewed as files not as BD disc.
As I had this perfectly and flawless with media encoder 5, something is wrong with my media encoder 6.0.1 and the preset mpeg 2 with dolby audio.
I do have CS5 and other adobe installed at the same machine: win 7 professional service pack1-12GB ram-i7-2,66-Quadro 4000,and two raids.
I did several tests and spent great hours with this matter (no results)
Any ideas or a solution please ?
Thank you

I had the same issue with Media Encoder CS6 when encoding m2ts files. This issue disappeared magically after installing the latest trial version of "Adobe Premier Pro" from adobe.com. Now the media encoder works just fine and encodes with audio without any issues. Looks like "Premier Pro" installed/updated some system files required for Media Encoder. The great thing is that even after uninstalling the "Premier Pro" completely from the system, "Media Encoder" still works. Try it yourself and see if it resolves your issue as well.

Creating mpeg2 file from a quicktime file

I have a laptop with quicktime 7.1.1 pro and I can export to mpeg2. My new G5 with quicktime 7.1.2 pro no longer has that option. I've been all over the internet trying puchase a 3rd party conversion software. Since apple compressor does not embed the audio into the mpeg file. it seperates video from audio.
I've tried mpeg Streamclip, mccoder from main concept to no avail.
Is there any hope?

I am not sure he ends up with an .mpg file in approved MPEG format with this method, succinct as it is. Also your directions starting with a VOB mean he is starting with an already compliant MPEG2 file in which case he can just edit in Streamclip and save it as an MPEG file.
There is a solution however - use Toast.
Add just about ANY format of video to the Toast video tab -on the left you are selecting make DVD Video. Toast will tell you if you have some oddball codec it will choke on. QT is fine.
In preferences you should also select the option to only manually delete coverted items (e.g. MPEG assets). MOre later.
Make a DVD with even one file, select a bit rate in the 5Mb/s and up range. Use CBR or VBR.
Save the .disc file then select save as disk image, which makes a .toast file that Toast will mount as a DVD. Mount that and rip the VOB to the desktop - you can rename that to filename.mpeg as it is an MPEG2 file and open in MPEG Streamclip to trim etc., and resave as an MPEG as well.
In the Roxio Converted Items folder you will have an M2V and .ac3 audio file of the converted clip which come in handy as well should you need them.

Mpeg2 file or M2TS file

Hello,
I did work work adobe premiere and Sony vegas where I can put a MPEG2 file with audio mux in it and I am able to play the file and see the audio on the timeline
With final cut pro I can import the file on the timeline but there is no audio. I need to convert it in a .mov file to use the audio.... Is there something that I miss is there a trick somewhere that I don't know.
Also for the m2ts file comming from my camera that seem to be a mpeg2 or 4 with Adobe premmiere and sony Vegas I'm able to work with the original file. But with AppleFCP I need to DO capture and transfert to pick wich one I need on the list and import it. So for a 1 hours file it take 30 minutes to convert. ho and it take twice place on the hard drive....
Is there also something I miss there also ?
Thanks for the help in advance
carl

Who is the manufacturer of your camera and what model is it?
The typical workflow for MPEG based cameras is to convert the footage to ProRes so that it can be edited.

OT: What viewers do you need to use ALL audio and video files?

I had a lot of trouble with audio and video files on my PC. I
now have a
MacBook Pro, which is a big improvement. But I still
frequently
encounter files that I can't use. I try to open them, but
Apple doesn't
know what to do with them. For example, I often encounter
unusable
videos while perusing news websites. I also have some audio
files with
.mva or .mvw extensions that don't work.
So what viwers/players do I need to download in order to be
able to play
every audio/video file that comes my way? iTunes handles .mp3
files, and
I also have QuickTime installed. I just viewed another video
after I
installed a Flash plugin. What else do I need to install?

Adobe Media Encoder won't open MPEG2 files

Hi All,
I'm hoping you can help me, I'm having some trouble with Adobe Media Encoder CS4, it won't open any MPEG2 files I throw at it.
They all open fine in Media Player Classic, MPC-HC and VideoLan, so I'm wondering what I'm doing wrong.
Any ideas greatfully appreciated.
Adobe Creative Suite 4 Design Premium
AME CS4 4.2.0.006
WinXP 64

Jim Simon, one came from a creative production house and a couple came from a website that provides various videos in various formats for testing video players.
Thanks for the information Colin Brougham. Can any MPEG 2 importers/decoders be used?
I'm new to AME so perhaps I don't understand how it works entirely but on the AME information page on the Adobe website it says that MPEG2 files can be imported, and there is no mention of only being able to do so with certain Adobe products (unless I missed it).
However, if I can open and play MPEG2 Files in various media players, surely there is a way to use the decoders from those to work with AME?
All advice greatly appreciated.

How to capture screen activity? (screen&audio to video file)

Hello,
I have to capture video desktop activity (including audio) to a file using JMF. I spent hours and hours searching this... a have studied a lot of classes, examples BUT I don't know how to bind them... how to record the actvity. My project is to record screen activity, upload on a server and finally control my computer remotely from an applet (or from another java desktop application). I will use HTTP streaming (what I record I upload on a server, then stream it to the client)
Can someone show me some hints or code for modifying JVidCap example from Sun? Someone else on Sun forum said he could do it but did not say how...
I just want to modify the video capturing so that I get the screen actifity recorded. I read nearly all examples possible including Screen Grabber...
Please help me!

MPEG2 files cause Finder to repeatedly relaunch...why?

Last night (and into this morning) I reinstalled all the components of FCP Studio 4.5 because I was having problems (Compressor wouldn't process, Motion wouldn't even start, etc.). This morning I exported an MPEG2 file from FCP 4.5 using the QT conversion option to my desktop because Compressor still wouldn't work (the dreaded "couldn't connect to background" yadda yadda yadda) and I wanted to burn it to a CD (it's all of 20 seconds long). I had to restart the computer, and when I did, the Finder kept quititng and trying to relaunch over and over (after about 2 seconds of trying).
I did some Googling and found out that the new security update for 10.4.9 causes some issues with MPEG2 files (something about not being able to display the preview correctly).
Firstly, I know I'm using an older version of FCP, but why can we create MPEG2 files if the operating system can't handle them? If they cause the system to crash, then where am I supposed to save them to so I can use them in DVD SP? I'd love to be able to follow the normal workflow (from FCP/Motion to Compressor to DVD SP), but I can't do that if I can't get Compressor to work the right way. I know there's some problem with QMaster, but I'm not sure what to do about it.
Any suggestions? I am using FCP HD Studio 4.5 on a G5 Dual 2GHz PowerPC running 10.4.9 with 1.5GB RAM and plenty of disc space. I've used all these apps in the past (a few months ago) with no problems, but now there seems to be all sorts of problems.
Thanks to everyone, as usual.

I remember something like this happening last time I tried to use Compressor, so I exported a QT file and used that in DVD SP.
Can you tell what's wrong?

How to combine discrete audio and video files?

I am working on a project which requires me to merge a video file with a PCM audio file from another source.
I just bought Compressor 4.1.1, expecting to be able to do exactly this.
The only "multiple input - single output" option I can see is creating a surround sound group, adding my audio as left and right channels, and then attaching the video.
This does not work. Pressing "add" at the end of the process does not result in a new job.
Help please!
G.

QT7 Pro is able to do this. Cost is $30.
In QT7 Pro, open up the audio and video files to be matched.
Select all the audio and then select copy
In the video window, put the playback head where you want the audio to start then select add to movie.
Verify the playback is as desired, then save the movie. Done.
Takes longer to describe the process than to do it.

Of course, life is good when the in point is exactly the same for both audio and video ...

No audio in Mpeg2 file.
