Merge .m4v Files

I want to merge one or more .m4v files into one.
What's the best way?

You can google search M4V Converter , it can convert M4V videos you bought or download from iTunes to MOV, MP4, VOB, etc or other popular video formats. Extracting the audio from M4V files as well by the M4V Converter Mac.

How to merge .m4v files with chapters included?

I am unable to merge two .m4v files in quicktime pro and keep their chapter structure. Is this even possible? I take a lot of time to build chapters into movies I make and I would like to be able to combine some AND keep the chapter structure.
Here is what I have:
Movie A: 12 chapters
Movie B: 10 chapters
open movie A in quicktime pro
open movie B in quicktime pro
copy movie B (command+A, command+C)
select movie A
push needs to end of movie A
paste clipboard (command+V)
Result:
Movie A now has it's original 12 chapters and then the added movie B is just one long section added on to the end of Movie A's last chapter.
Any help would be appreciated. This seems to be an ongoing question on many forums.

1) is there any way to use your method that give me a final .m4v?
Well, your questions are certainly getting harder. How a bout no, yes, and maybe.
a) No, I do not know of a direct approach for simply changing the file container. As you may have noted, QT now checks the Video Track "Sample Description" and if the extension does not match the description, QT sends you a "nastygram" modal message and refuses to open the file.
b) Yes, it can be done indirectly. In this case I used the SimpleMovieX ($35) from Aero Quartet of Catalonia, Spain. While I tend to use QT Pro and MPEG Streamclip for most day-to-day work, this application does have some unique features to which I resort when needed. One is the "Keyframe" combined indicator/skip option, one is its audio manipulations, and another is the way it handles H.264/AAC MOV file container conversion. (I also do a lot of "track management" work that leaves me in an MOV file when I actually want MP4 or M4V file container features like being able to associate external "artwork" images in iTunes.) In any event, this application does actually go through and correct the descriptors before it copies the appropriate data to the new container making QT ever so happy with the new MP4 container. At this point, if I modify the MP4 Extension to M4V in the Finder, QT then does not issue the modal message and does use iTunes as the default application to open the file.
c) Maybe the file is considered to be a real M4V file and maybe it is not. I have not, for instance tried to add a "Passthrough" AC3 secondary audio track and check to see if the resulting file will play correctly via TV. So there may yet be some internal distinctions of which I am yet unaware. Other than that, the file does indeed seem to function as any other iTunes file created by direct M4V data compressed export.
Anyway, this is from the "for whatever it is worth" department and you can invest $35 in the application or try to find another application capable of doing the same thing. MPEG Streamclip, for instance, will not work here but I have not actually looked around for anything else.
2) if I use the final .MOV that you get at the end of your tutorial, will exporting as "apple tv" or mpeg 4 etc. compress it again?
Yes, it will. In addition, depending on the application used to perform the export, you may lose the chapter track also.

2nd Audio track from merged .m4v files does not play on iPod Touch

I used Handbrake to encode two .m4v files of a concert DVD that spans two DVDs. I then took those two files and combined them into Quicktime Pro to create a single .m4v file. The file plays fine in QT but when I transfer the file to my ipod, only the first audio track (from the first file) plays. Once the video from the second file plays, the audio is silent. Here's what the movie properties look like:
Enabled Name Start Time Duration Format
====================================================
Y Video Track -- 0:00:00:00 -- 2:21:53:90 -- H.264
Y Audio Track1 -- 0:00:00:00 -- 2:21:53:90 -- AAC
Y Audio Track2 -- 1:27:28:87 -- 0:54:24:02 -- AAC
N Text Track -- 0:00:00:00 -- 2:21:53:90 -- Text
Any suggestions?
Thanks,
Dan

So basically, anytime I combine more than one mp4 file in QT7 Pro, it will always create multiple audio tracks when doing a simple "save as" (vs. export as)
Not exactly. QT has it own set of rules. As you noted, the video track had no problem merging into a single track. This would not have happened if you had merged video compressed differently or added an image/stretched image sequence. Not knowing your specific work flow or settings, I hesitate to make any claims here. Frankly, when merging audio, I normally prefer to use GarageBand when I want to create a single master audio track and still retain control of the other tracks for mixing purposes. However, I could just as well have exported the audio in the original file using QT Pro to a single audio file and used that audio track to replace both original tracks keeping both the original video and chapter tracks. It is all a matter of which work flow you consider easiest for a particular job or project.
If I've exported out my chapter file as a plain text file, how do I go about reintegrating that withing the final mp4 file using QT?
http://www.apple.com/quicktime/tutorials/chaptertracks.html
The above link is a somewhat old tutorial explaining how to create a chapter text track from scratch. Since you already have the chapter track, just refer to the steps indicating how to add the text file back to your main movie file. (Ignore the step that says to set a "Preload" option as this pop-up has been removed.)

I have created a .m4v file from iPhoto and would like to share it with someone else knowing that the file is quiet large (86 Mo), i used to share file with mobileme, how Can I do that with iCloud ? or another way....

In iphoto, I have create a diaporama which I exported to itunes as a m4v file. I would like to share this file with someone but it is too big to send it via email (84 Mo). This file is now in my films in itunes. Is there a way to share it via icloud.
I used to share files using mobileme which I cannot use anymore.
Thanks for your help,
Eric

How recently did you switch? If it's less than 60 days, then Verizon simply reinstates your previous account. The fact that you were on the EDGE plan and mailed the devices back, and they apparently are somewhere in the system, could cause complications, and it might just work out that you just go back on the same plan and they set you up with the same devices. I'm not sure how it will go - but since you are still being billed for the devices...

PC users can't open iMovie .m4v file

my son made a really cute movie in iMovie, and saved it as an iTunes file, which put it in the .m4v format. i emailed the .m4v file to all our family and friends ... and the PC users can't open the file. can i do something about this (ie. save it in a different format)? please explain it to me in real simple terms ... i am a Luddite. thanks!

You could always point out that anyone whould really wants to watch it could download and install the free QT 7 Player in much the same way that many Mac users would have to download and install either a WMV Player or a WMV component for their QT Player.
You realize, of course, things will likely get worse once you start "customizing" your exports of each recipient? My Sister only wants WMV 9 ($50 for Microsoft "approved" bi-directional components), my brother-in-law "prefers" DivX 6 minimum ($20 for the components), my nieces are into YouTube (posted directly from iMovie '08 for the price of iLife '08) and want everything posted there, and my Aunt (whose computer is more than a decade old) only wants MPEG-1 (which I used to make with iVCD (don't remember what that used to cost or Ti Toast 9 at $80) and of course there is always Visual Hub (at just under $24) for all of the others who will settle for older AVI or WMV files. You can also try exporting some of the "less recent" or "older" codecs like MPEG-4/AAC, Sorenson Video, Sorenson 3 Video, H.263, Cinepak, etc. There are dozens of audio and video codecs that can be combined in in hundreds of combination and placed in various file containers but the problem is you will probably never find a single compression format that really satisfies everyone all of the time. So before anyone can "draw you a map," you will have to make a decision as to "down which road you wish to travel."

.m4v file icons have become solid white in Finder under iTunes 10.6.3

Hi there,
I just discovered this little annoyance... I thought I'd seen the last of it under a prior version of iTunes, but it may have come back.
iTunes video files (.m4v container files) have suddenly defaulted to a plain white icon in the Finder - desktop, folders, etc. - upon updating to iTunes 10.6.3. The generic blue "notes" icon with "M4V" has disappeared, and will not reappear upon attempting to clear out the icon during a Get Info.
Strangely, if "Show icon preview" is checked under Finder's View Options, it will display any associated album art with the .m4v file correctly - it just so happens that something occurred with the default icons.
I rebuilt the Launch Services just in case, and these files by default still open with iTunes as per usual. Checked for corrupt .plist files (even trashed com.apple.finder.plist) and cleared some caches out, ran maintenance scripts, etc. to cover any possible loose ends, but this issue is still present.
I recently upgraded to Lion 10.7.4 (long time SL holdout) but everything was normal under iTunes 10.6.2 - so I cannot determine whether this is a Lion issue or an iTunes issue. I am going to post this in the iTunes forum as well, but has anyone else noticed this recently? If so, what did you do to fix this?
Thanks all,
Steve

That's the point to where I was getting - without icon previews, the default icon for .m4v files should be the following:
(This was just taken from my wife's MacBook Pro, still on iTunes 10.6.2 but running Snow Leopard 10.6.8)
Under Lion (10.7.4) and iTunes 10.6.3, the default icon (no previews) is empty white, which I do not believe should be - I had the above generic icon for .m4v files in Lion under 10.6.2.
Yet iTunes-associated audio files are fine: (from my iMac)
Strange, isn't it??

I have m4v files that have subtitles and sound options they play fine on my computer in itunes and but when i watch them on my apple tv there is video but no sound ... why ?

I have m4v files that have subtitles and sound options they play fine on my computer in itunes and but when i watch them on my apple tv there is video but no sound ... why ? all my other videos are fine and they in mp4 format.

Mov is a container format, you'd need to look at the codec used by the movie file inside the container to know whether it will work with the Apple TV or not.

Hyper-v VM - merged .avhd files - now cant start as missing .vsv file

Hi All,
Yesterday i shut down one of our VMs to allow the snapshots to merge and then tried to start the VM but got the following error:
'VM' could not initialize.
An attempt to initialize VM save state failed.
'VM' could not initialize. (Virtual Machine ID ........)
'VM' could not create or access saved state file E:\....... .vsv
When i looked for one i realised that a .vsv file doesnt exist for the VM. I thought the .vsv file was a temporary file and that the VM should happily start without it?
Any help is much appreciated!

Hi jrussellcj,
"I thought the .vsv file was a temporary file and that the VM should happily start without it?"
Yes , if all of the snapshots are merged properly , there will be no .bin and .VSV remained for that VM .
Please check the snapshots' folders to ensure that there is no files .
And I agree with Philip's suggestion .
If the merged VHD file can works well in a new VM then you may no longer need the old VM .
Best Regards

How to merge pdf files into one pdf file?

In E-Rec we need the capability to mass printing for correspondance. There i want to merge pdf files for candidates into one pdf file. I am doing the following:
Data: lv_document1           TYPE rcf_s_cs_document_content.
LOOP AT activity_object_tab INTO ls_activity_object.
    lo_act_corr ?= ls_activity_object-activity.
     CALL METHOD lo_act_corr->process_document
       EXPORTING
         channel = 'FRONTEND'
       IMPORTING
         document = lv_document1.
ENDLOOP.
Now lv_document1 contains the pdf file in lv_document1-DOCUMENT_X which is of type RAWSTRING.
This works for one candidate, in this case the pdf for last candidate will be displayed.
But how would i append in the loop or what would i need to do display all candidates in one pdf.
Any help will be appreciated.
Thanks

2.98GB .m4v File won't import into iMove 11?

I ripped a family movie off a DVD converted from a VHS tape, using Handbrake into an .m4v file and have tried twice now to import it into iMovie 11 without success. Is there some kind of limit that would make this fail? It starts building a .mov file in the iMove projects directory and I can see the file size increase until the very end (2 hours later) and then it gets deleted. Ugly. What am I doing wrong or are my expectations of iMovie too high?

So after waiting all this time, iMovie simply deleted the file the end without adding it to my event. No error. No joy and almost 13GB.

I get error 23132 when trying to open a M4v file

I use to be able to play m4v files on both iTunes and Quick Time 7. Suddenly, after upgrading iTunes, I get error 23132 when trying to open a M4v file. How do I fix it to view the files on QuickTime?

There is software you installed to work with your company's cloud service, update it or talk to the developer.

Is there a simple way to merge mp3 files into one mp3 file:

Is there a way to simply merge multiple mp3s into one? I have audacity; however, that program becomes cumbersome when merging multiple files.
My thanks to anyone for help on this one.

I have audacity; however, that program becomes cumbersome when merging multiple files.
How true! I had to do this recently and used Audacity for the task, having nothing else suitable (that I know of, at least). My method was to open each MP3 in its own Audacity window, select and copy all of the second file, close its window, and paste it into the end of the first file, repeating the process for each additional MP3. After all the pieces are in place, export the whole thing as a new MP3. This was cumbersome indeed, and it took concentration to remember which file was which and avoid assembling the pieces in the wrong order. This description will make a lot more sense to someone who has done it than to anyone who hasn't.
All of this is to say that if you get a better answer than my kludgey Audacity method, I'll be as grateful as you are.

I want to merge mp3 files into one file so i can play a mix in i tunes without pauze

i want to merge mp3 files into one file so i can play a mix in i tunes without pauze

Audacity is what you need.
Obviously you need to create a new MP3 file of the combined songs and not delete the originals.
If your DJ-ing and/or just have too many songs to do that, then look at the free VirtualDJHome version, gives you a lot of control over your music playback.

RoboHelp HTML Version 8 - Merging AIR files

We use Webhelp Pro to merge 19 separate projects into a single merged help file. Can I do that with AIR output, and if so, how? Can anyone point me to a tutorial?

Hi there!
I agree with what both Pater and Rick have said, but there may be another way to acheive your objective.
I have merged 4 additional help systems into our Knowledgebase as an AIR module.
How? By importing each project's topics into the Knnowledgebase and the making a top level TOC entry for each components.
I got this idea from a comment that Rick made noting that the TOC is simply a set of links to the topics. In a merged webhelp, the TOC entry for the child projects are simply placeholders to make the multiple projects appear as a unified whole.
So in the case I am describing, the "merged" Top level TOC entries actually point to the topics inside the AIR module.
While I was doing this, there were some issues with the search. While debugging this issue, I discovered that the .cpd file was getting rather large each time I added another system. (over 2.5meg) To fix this, i just kept deleting the .cpd after i mporting each help system and let RH rebuild it for me. Search problem solved!
(close merged project/delete project.cpd/reopenproject)
Now, whether or not this will work for you would seem in part to depend on:
The way your 19 subprojects folders are structured
Number of topics in total (we now have about 500 topics form all the merged modules, not sure what the limits for AIRHelp are)
How you are handling your RH Source Control process
The attached snag shows the merged Knowledgebase TOC with one of the Help systems topics opened for you to see. It's all there and it works. My team uses this tool every day and they love the fact that all the files they need are in one interface with commenting and autoupdating.
Hope thos helps or at least gives you something to consider
Ciao

What is the best way to merge a file content into log file

What is the best way to merge a file content into log file.
In worst case, I will read the file line by line as string, then use
logger.info(lineString)to output to log file.
However, is there better way to do this?
The eventual log file will be something like:
log message 1
log message 2
content from file line 1
content from file line 2
content from file line 3
log message 3
log message 4Thanks

1. What do you mean by better?
I would like to see better performance. read line by line and log each line as string can be slow. Did you measure this and determine that it is actually a problem for your application? Or are you guessing?
Regardless of what you do you are still going to need to read the file.

2.The only better way I can think of is not having to do it, but I assume you have a very good reason to want to do this.
Yes, I have to do it beacuse the requirement is to have that file content be part of logging.
Any idea?How is it supposed to be part of it? For example which of the following is better?
        File AAA - contents
                   First Line
                   Second Line XXX
        Log 1
                2009-03-27 DEBUG: Random preceding line
                2009-03-27 DEBUG: First Line
                2009-03-27 DEBUG: Second Line XXX
                2009-03-27 DEBUG: Random following line
        Log 2
                2009-03-27 DEBUG: Random preceding line
                2009-03-27 DEBUG: ----- File: AAA -------------
                First Line
                Second Line XXX
                2009-03-27 DEBUG: Random following lineBoth of the above have some advantages and disadvantages.
The first in a mult-threaded app can end up with intermittent log entries in between lines, so having log lines with thread ids becomes important.
The first can be created by reading one line at a time and posting one at a time.
The second can be created by reading the entire file as a single string and then posting using a single log statement.
