Quicktime X/7 & .m2v files

Just upgraded to Snow Leopard, and in my workflow I export files from Compressor to a DVD format for burning (.m2v). I use to preview these .m2v files in Quicktime 7 before burning.
Unfortunately for me, Quicktime X won't recognise and play these .m2v files and when I right click and open with Quicktime 7, QT7 won't recognise it as a movie file.
I know I can use VLC, but don't want to, as VLC doesn't seem to render them nicely as Quicktime does.
Thanks,
Thomas

exactly the same problem here - mpeg2 played fine before Snow Leopard (have QT Pro and MPEG2 component).
VLC continues to play the same video no problem - no messing around with files in the right place there.
Apple's practice of deleting stuff in my Time Machine backup has made me doubt whether anything in Time Machine backups can now be relied upon. Specifically, I'm talking about my unlocked iPhone custom restores which I found in the trashcan which had been ALTERED (such that filesize was identical but all bytes were zeroed out) and trashed following the Snow Leopard upgrade.
I was only able to see that my iPhone custom restores had been trashed and altered by diff/cmp with a copy I fortunately had in my SuperDuper bootable Leopard image taken the day before - all records of the iTunes directory where these were originally located had been erased in every snapshot of Time Machine that I had - back as far as 6 months.
What a joke - 2009 and Apple still can't get MPEGs to play in a default install. Worse, they can't preserve the functionality and license integrity on system updates.
Snow Leopard has been a disaster for me (what's with the trashcan taking 20minutes to empty?)

.m2v file not playing in Quicktime Pro

I just purchased Quicktime Pro 7.6. I have a bunch of MPEG2 (.m2v) files that worked on my old iMac and am trying to get them to work on my new iMac. When I open the MPEG2 files using Quicktime, I get a "the file is not a movie file" error. Again, these are the same MPEG2 files that worked on my previous iMac. When I open the files using VLC, the video works fine, but it VLC doesn't play MPEG2s with audio, nor can it convert. Any idea why Quicktime Pro would not be working? I've tried the files with and without the .m2v extensions also.

There should be a second, audio file that is associated with the m2v. The m2v container does not have the audio. VLC probably can't find the audio track.
So in other words, you guys are saying that Quicktime Pro does not come with the MPEG-2 player component, and that will be another $20?
Unfortunately, that is correct. Another option is [ffmpegx|http://ffmpegx.com>. It is shareware and costs $15.

Can't open m2v file with mpeg2

I upgraded my QT mpegp2 to 6.4 buy putting in my FCP 4 SS# then dowloading it from the website but all my m2v file got the compresser icon on them and when I try to open them I get the error "QuickTime cannot open the file: "1_2.m2v"
it is not a file that QuickTime understands (-2048)" I tried reinstalling but still no luck.
Thanks.

Try changing the extension to mpg

Issue with HDV m2v files and importprocessserver.exe

I have 18 or so 40Min m2v files at 1440x1080 29.7P, These file go into premiere and edit with no problem. But when I close premiere and reopen it the project takes over 2 hours to load. The reason for the slowdown is that ImporterProcessServer.exe is going through all 400 or so GB of video and reading it all in again. Now I know that premiere needs to make mpegindex files for m2v's and it does do that, all the videos has a corresponding entry in the media cache and a mpegindex file in their directory. Does anyone know why its still reading through all the video files? I'm 100% positive this is not a hardware issue but just because I'm sure someone will ask:
3.166GHZ Dual Core
8GB Ram
2x80GB raid 0 (os)
2x1TB raid 0 (footage)
both raids are recently defragmented and have in excess of 40% diskspace free
windows vista 64bit

As I stated in the original post the only preset I have that
even comes close to matching a P2 Preset is " HDVCPRO50/720p/24pn" .
I have installed all the P2 software that came with camera and all drivers. I have looked at the Panasonic site. Called Adobe and no help only thing is Adobe said I needed Quicktime 7.6.5 not 7.6.6.

Urgent!! Problems muxing .m2v files and audio!! MPEG Streamclip/Compressor

Hello!
I am under an urgent deadline to upload a short 6 min documentary clip for a client to review for screening this week. The footage was shot in 1080/60i HDV.
Usually, I find the best quality and fastest way to do this is to export directly from my FCP sequence using the '150 min Best Quality' DVD settings in compressor to get an .m2v video file and .ac3 audio file. Then I open the .m2v files in MPEG Streamclip which links it with my .ac3 file, then do 'Export MPEG with MP-2 audio". This gives me a single, muxed file that I can then upload to YouTube or Vimeo.
However, with this project, when I open up my .m2v file in MPEG Streamclip, it's recognizing the .ac3 file and I can see the info for it in the MPEG Streamclip window, but when I play the file in MPEG Streamclip or mux it, I don't hear any audio. Furthermore, after about 5 seconds into the clip, the playhead will continue moving, but the video will freeze, then maybe pick up again later. The .m2v video will play back smoothly in VLC player or Quicktime player, but not in MPEG Streamclip.
I've tried exporting different little sections of the timeline to see if maybe I had some corrupted footage or whatnot. I even exported a small clip from an older HDV project to test. But no matter where I export from, I am running into the same problem. I can bring the .m2v file and .ac3 file into DVD Studio Pro and burn a DVD with no problem, but I can't mux them. If I build the DVD file in DVD SP and try to open the .VOB file with MPEG Streamclip, I get the same problem. I even tried using a different software to mux (ffmpegX) but to no avail. When I try with ffmpegX, it either tells me I'm dropping frames, or if it works and it muxes it, when I open the MPEG file, it'll stutter at about 5 seconds in as well and I can't hear any audio, even though there is supposed to be audio in the muxed file.
I think I might have updated my Quicktime a few days ago with the system update, and maybe updated a few other things, so I don't know if this has any bearing on the problems I'm running into. But I was able just a few days ago to export HDV 1080/60i using this workflow without any problems.
I realize I have other export options, but this always seems to me to be the best quality and fastest way of doing it vs. encoding an H.264 which, on my machine is RIDICULOUSLY slow...I need to be uploading multiple versions of the cut to the client, and really need help! Thanks so much in advance!

what you want is an m2v program file. Export a reference copy from FCP (uncheck Make Movie Self Contained") That's very fast. Bring it into Compressor. In the settings panel find the MPEG-2 settings folder. Select Program Stream. Adjust to your liking and run. The audio and video will already be "muxed" when it's done and using compressor 3 you can set it to upload to YouTube, Mobile or similar sites.

M2v files from compressor will not play in QT or DVD Studio Pro

I have 2 hours of HD footage that I am trying to put on a DVD. I tried exporting the entire thing (twice) to an mpeg2 but the resulting file would not open and froze quicktime. I then tried exporting the chapters individually. Even though I tried this twice, only the first clip worked. I then copied each chapter into a new sequence in FCP and exported each sequence to Compressor. This time, I could only open one of the 15 or so files in QT, but I could not even import that into DVD Studio Pro (it said it was an invalid file type). I have been using all the same settings, so I am not sure why chapter 1 works fine everywhere, chapter 2 works in QT but not DVD Studio Pro and the remaining chapters do not work anywhere. Anyone got any ideas as to what to do/try next?

I know that it will take a while, but after two tries exporting the whole thing and the result not working, I broke it up into smaller, 10 minute sections hoping that the computer would be able to handle them better and if one is bad, it is easier to fix than re-doing the entire thing.
The Compressor settings I am using: DVD Best Quality 150 minutes with all the default settings except that I put stream usage at HD DVD. I have also tried using Fastest Encode 150 minutes, also changing the stream usage.
I exported 20 minutes with Fastest Encode and changed the file format to 'H.264 for DVD Studio Pro' and it worked, but it is a mov file that is much bigger than the mpeg2 (m2v) file.
I started the compressor to work on the remaining hour at night and then left it until the next afternoon, but when I came back, it said there were 60+ hours remaining, but FCP was counting off the frames. I left it for another couple hours, hoping that compressor was simply estimating wrong, but when I came back, it said there were 93 hours remaining until it would be done. I canceled it and restarted the computer.

M2v files are not being read on my new mac.

I installed quicktime pro, dvd studio pro 3, final cut pro 4...and my m2v files will not play in quicktime or the preview window. I get a pop up window saying, "Movie could not be opened. not a movie file." With any of those programs installed, shouldn't mpeg-2 codec be installed automatically? I plugged in my external HD with all my movies on it back up to my old g4...and they play fine there. I noticed there was a problem on the new mac when i tried to import them into DVD studio pro. So how do i get the m2v files to be viewable in quicktime and in DVD studio pro?
Thanks,
Tony

You must also install the MPEG2 playback component. It is also a good idea to use MPEG Streamclip which has some nice features for MPEG.

Finder relaunches when viewing M2V file info ...

I'm not sure if this is the right forum for this question, but I imagine I'm most likely to find an answer here. So, here it goes:
As the topic states, the Finder relaunches itself whenever I try to view the file info of a M2V file. This happens when I'm attempting to "Get Info" or simply scrolling the window to the right. More specifically, this occurs when I reach the "Kind" column (removing "Kind" from the window disables the problem). While I wouldn't mind simply excluding "Kind" from my windows, I am still unable to "Get Info" on any M2V files. Any ideas why this may be occuring?
The Files:
- compressed with Compressor 2.0.1, via Final Cut Pro 5.0.2 (source media uses "Animation" codec)
- MPEG-2 compression
- 1-pass, 7.5 Mbs CBR, 29.97fps progressive, 720x 480
The System:
- Dual 1.8GHz PowerPC G5
- 2.5 GB RAM
- 372.62 GB SATA RAID (96.11 GB available)
- OS 10.3.9 (all "Software Updates" installed)
Any input would be greatly appreciated. Thanks in advance!
take care & God bless,
Steve Cole

I suspect you are seeing a variation of the problem discussed in the following link:
Waymen, "quicktime 7.0.2. and m2v" #4, 11:35pm Sep 8, 2005 CDT
However, since you experience a crash in the Finder when you try to access the Get Info you will have to use a different technique to reset the file association. Select one of the .m2v files that is giving you a problem and then do a control-click (or right click) to show the Finder's contextual menu, then go to the Open With item and select Other... and click the Always Open With checkbox and then navigate to your QuickTime Player and select it as the application to open. This will change the file association for the .m2v file kind and it should fix the problem. You may want to do a system reboot after you do the above fix.
Summary: control-click or right click on the problem .m2v file then:
Open With -> Other... -> (select "Always Open With" checkbox) -> Open (choose) QuickTime Player.
If this suggestion helps in any way, a confirmation or acknowledgment would be appreciated, since that would also help others who may be having the same difficulty. Do for others as you would have them help you.

Compressor now creating unusable .m2v files - on two different systems

Hi all,
This week I was in Sydney attempting to show a friend how to use compressor.
I showed him the way I use it and all was fine until the file was encoded. The resulting audio file was fine, but the video file with a m2v extension ended up with an icon that looked more like a document that a video-related one that compressor normally makes.
DVD Studio would crash when I attempted to import it.
I thought there was a problem with his system and recommended he reinstall compressor, amongst other things.
Now today I am at home and attempting to encode and guess what? My computer is now doing EXACTLY the same thing. Creating unusable .m2v video component files with a document-looking icon.
Am I doing something wrong here and missing it?
Thanks in advance.

This may be an old problem (.m2v file kind) for which I've posted the fix several times (seems like nearly ever week someone posts a report like yours).
The following procedure may solve your problem (however, you may have to change your Finder view to Icons or Lists in order to access the problematic .m2v files):
Select one of the .m2v files that is giving you a problem and then do a control-click (or right click) to show the Finder's contextual menu, then go to the Open With item and select Other... and click the Always Open With checkbox and then navigate to your QuickTime Player and select it as the application to open. This will change the file association for the .m2v file kind and it should fix the problem. You may want to do a system reboot after you do the above fix.
Summary: control-click or right click on the problem .m2v file then:
Open With -> Other... -> (select "Always Open With" checkbox) -> Open (choose) QuickTime Player.

M2v files not playing

I have some older m2v files that will will not show any video in DVDSP the audio plays. Do I need to convert these?

If they are proper m2v streams (not HD and not m2v with audio) they should work...are these m2vs with audio in them (transport streams?)
When you open them in QuickTime do you have sound and video tracks? Sounds like you may....but if they are transport/multiplexed streams you need to make the video part seperate

DVDSP 3 Crashes importing m2v files

Hi, I´ve been trying to finish a project on DVDSP3 for 5 days now. Always the same problem. I´ve encoded a FCP rendered sequence to m2v file using compressor. The process was sucessful!. The thing is when I try to import the file into DVDSP using Palette crashes automatically. I started trying other ways of importing and the same thing over and over again. I´ve tried to open the file on Quicktime and works perfectly, the preview works fine on finder. Everything seems to be in order. But when dragging the file into the timeline the program crashes. Sometimes also crashes when I open the program. I´ve repaired the disk permissions, downloaded the proapp update and installed it again.... nothing. Tried also re-installing the DVDSP and nothing. I tried importing the m2v file as an asset and the file appears on the list but when dragging it to the timeline, guess what?: crashes again. Finally I took the FCP project and compressed it again, thought maybe the other file was corrupted. Everything was fine until I tried dragging the file to the timeline when DVDSP crashed again... sorry but i´m f@*ing tired of this. CAN ANYONE HELP!!!!!!!...
Like i said before it´s been my 5th day in a row and nothing seems to work... Any help will be great!
Sorry for the long text but I tried to explain my process in detail so proper help can be found...
Thanks in advance...
PS: have noticed that every topic with this kind of problem never got an answer...
very dissapointed with DVDSP... will not recommend to no-one...
Sorry for the bad english

Hi Sebakd, welcome to the discussions.
Download and install the proapplication support file from Apple...
http://www.apple.com/support/downloads/proapplicationsupport31macosx104.html
If that doesn't fix it, come back and let us know - there will be a simple reason for the issue.
In 9/10 cases the proapp support file fixes the problem, and in the vast majority of the posts citing this issue that fix is recommended in the replies for all to see.

Attaching audio and editing M2V files

I have about 200 M2V files that were provided to me for use in a Final Cut Pro project. They originated from about six different HDV cameras in 1080i60. The clips were captured to a PC running some version of Pinnacle software on-site at an event. Each M2V file has no sound, but is accompanied by a pair of WAV files. Left and right channels. I have MPEG Streamclip to transcode the clips, but the problem I am having is figuring out how to get the audio attached so that it can be edited. Also, I'm wondering if this can be done without transcoding with generational loss. Since they are HDV files, can they be converted to Quicktime HDV wrapper? Can anyone shed any light on this for me? Thanks.

What are the pixel dimensions of the m2v files? They should open in quicktime player and you should be able to check there. Some compression/conversion utilities allow you to attach audio files during the encoding. Don't think compressor will do it. I will see if Squeeze will do it, if you like, but Squeeze costs money.

M2v files suddenly have blank icon and open droplet app

Hi everybody
Suddenly all my m2v files have lost their quicktime icon. When I double click on them, they open an application called droplet which I've never seen before and do not know what it's for.
Yet, if I drag the files to the quicktime (pro) icon they play.
In the past week I upgraded to the last version. I also was trying to figure out how to export wmv files from quicktime and installed a demo of popwire technology. Maybe I updated Perian as well.
Any idea of how to get my files to open as they used to?
In the Quicktime Library I don't see any mpeg2 component.
(I have Final cut Studio 1)
Any recommendation of a list of Quicktime necessary components one would need to play end export most internet formats, that do not create conflicts with each other?
Thank you very much in advance

Hi-light one of the video's and get info in the finder... There you will see, "open with." Pick Quicktime and then click on change all tab. All of these video files (mpeg2) should open with Qt.

Finder restarts if a .m2v file is in the window

I'm going to post this question in several forums because I'm not sure if it's a hardware or software problem/glitch.
I am using Final Cut Pro 4.5HD. After I complete a poject, I export the file out of Compressor to create a .m2v file (mpeg-2). When I try to open the window/folder in which the .m2v file resides (I usually export it to an external hard drive's main window), the window opens with no file names showing and stays open for about a second, then the Finder restarts without that window being open. The same thing happens no matter where I export the .m2v file, meaning that the same thing happens with that window.
I have Quicktime Pro 7.1.6 and the MPEG-2 plug-in, but I'm not sure if the plug-in is working or not. I purchased the plug-in in June 2005 and have since upgraded Quicktime and the OS several times.
I'm assuming that because I can export .m2v files that the MPEG-2 plug-in is working, but I've read that it's used for playback only.
Does anyone have any idea why this is happening?
I also need to save an AIFF file as an mpg1...any suggestions?
Thanks in advance,

Try this, as it's possible your system just doesn't know what program to associate with .m2v files.
Get info (apple+I) on one of your .m2v files
In the "Open with" dropdown find QuickTime Player.
If it isn't in the list choose "other" and navigate to QuickTime Player in your Applications folder.
Then click on the "Change all" button.

How do I combine an .m2v file and an .ac3 file into a .mov file ??

Hello,
I had a question regarding Demuxing M2V and AC3 files so that they can be combined into a .mov file.
A few years ago I converted a .mov file into an .m2v and an .AC3 using Final Cut Pro. I lost the FCP Project and .mov files and only have the .m2v and .ac3 files left. When I tried to combine them together in FCP, the audio did not match up anymore even though it matches on DVD Studio Pro. I was told that I needed demux the files. How do you do that ???
Thanks so much for your time !!!
Happy New Year!

A few years ago I converted a .mov file into an .m2v and an .AC3 using Final Cut Pro. I lost the FCP Project and .mov files and only have the .m2v and .ac3 files left. When I tried to combine them together in FCP, the audio did not match up anymore even though it matches on DVD Studio Pro. I was told that I needed demux the files. How do you do that ???
Doug,
Am posting the workflow discussed in my last email here in the event others might be interested.
Best workflow I've found to resync and convert the M2V/AC3 elementary stream files to an MOV ProRes422/AIFF file are as follows:
1) Convert the AC3 audio file to AIFF. (My system is configured for AC3 so I used QT 7 Pro here. My only compaint at this point is that my original AC3 file was DD5.1 and my QT 7 Pro component only supports stereo conversions.)
2) Simultaneously drop-import the original M2V file along with the converted AIFF file to MPEG Streamclip (requires the QT MPEG-2 Playback component be installed).
3) Sample playback of the combined data to ensure audio and video are correctly in sync throughout the file.
4) Use the MPEG Streamclip "Export to QuickTime" File menu option to export the current date to the target Apple ProRes422 video target you want and pass the AIFF PCM audio through to the MOV file container without further processing.
5) Import the ProRes422/AIFF MOV file to your FCP bin and reset project default codec use to match imported file when asked so you don't have to do any re-rendering for final output.
6) I re-checked file playback in the Preview window to ensure A/V was still in sync before beginning edits in the project timeline.
All went well for me using this workflow. You may want to give it a try and let us know if it worked as well for you.
Good luck!
