Apr 27, 2015 8:48 AM in response to drrbr1by Jon Walker,Sorry for taking so long to get back to you. Had to respond to birthday wishes from the family—or face the consequences...
Greetings from across the 'pond.' Didn't realize you were posting from the UK and on a different time schedule. In any case,—on to business.
The file was there because I "tested" the posted link to try it before posting on this forum. In doing so it seems I deleted it.
I did get a message saying something to the effect that "You already have this file". Perhaps as a result Dropbox deleted it?
I have uploaded it to Dropbox again and this time i have left it at that - no test.
The new link is:
https://www.dropbox.com/s/otdbdbax7lp9gi0/20150426_183535A.mov?dl=0
Which is the same as the old one. However it is certainly ther with a thumbnail picture.
I will see if I can also send it to your profile as requested.
Downloaded the file earlier this AM—and without problem this time. Looks like I was wrong regarding an errant data rate/sampling rate issue. Luckily this problem has the same basic solution set.
Your basic problem is that QT does not like the manner in which your device muxed the audio to the MOV file container. Sample file audio had a data rate on the order of 43 Kbps and a sampling rate of 22.050 KHz and is what I would normally consider M4B audiobook quality. This is a valid combination compatibly with all QT based apps. Unfortunately, QT apps can't seem to located the audio data rate info in the file as muxed by your device:
As you can see from the QT 7 "Properties" window above, QT is reading the data rate as 0.0 Kbps and considers the audio track to be empty. To remedy the problem, I used an old third-party muxing utility to copy the data from your original file to a new MP4 file container with corrected headers. I then opened the file in both QT X and QT 7, as well as, QL to ensure it was now playable. Since I already had the file opened in QT 7 Pro, I used it to copy the data from the MP4 back to an MOV container—arriving "full circle" at an MOV file that contains your original device data but is QT/QL compatible with any current Mac OS X system ss you can see in the "Properties" window image that now "sees" the audio data below:
Basically, there are many ways to make your files QT compatible. The method I used preserves the original level of quality but may not be worth the effort since you can view the files as they are in VLC. On the other hand, if you plan to "share" the files or post them to the internet as smaller, more web compatible files, then you could use an app like HandBrake (free download) for conversion to various preset or custom settings. In any case, I will post a copy of the resulting MOV file to my personal server for download and testing on your system. Be advised that I periodically clean out these files, so don't be surprised if/when the link below becomes orphaned:
Best wishes & enjoy...

Apr 27, 2015 12:33 PM in response to Jon Walkerby drrbr1,Thank you Jon for the detailed and comprehensive explanation.
I think I finally understand! It is now clear that with this camera I will have to find a work-around as required. Hopefully that will not be too often!
As you have seen, this is an in-car camera and last week I had need to make a DVD disc of an "incident" where a lady drove into my car whilst I was parked!
I was in the car and the camera(s) were running (it records front and rear). Fortunately she is on a recording saying " I really should be wearing glasses with my eyes. I'm just too proud".
I had a lot of trouble making the disc and as you can understand the audio is vital.
Thanks again for your help - it is very much appreciated.
Thank you Drew for your interest and observations.

Apr 27, 2015 1:57 PM in response to drrbr1by Drew Reece,As Jon said, Handbrake is an easy way to handle the conversion - the app crashed for some reason with your file but the command line tool 'handbrakecli' worked for me.
If you are looking for a way to just process a lot of files with minimal effort try Automator. It has a built in Quicktime action 'Encode media' but that also fails to work! You can work around the issue with handbrakecli & a 'do shell script action', but this starts to become a little convoluted (but it does work).
The benefit of a tool like Automator so that you can process future items without the involved setup, it can be saved as a little application that processes files dropped onto it.
Ask if you want to use that, you do need the 'handbrakecli' tool to be installed separately.
Below is an 'Automator Application' that works for me, but you would need to install HandBrakeCLI into the same location or change the path (/usr/local/bin/).
The command line tool is at https://handbrake.fr/downloads.php
P.S.
Burn is a free app that can make Video-DVD's, or Toast is better you have a regular need to create DVD's.

Wasn't sure what you were referring to when you said "DVD disc." As Drew indicated, Titanium Toast, Toast Burn, etc. are all good for creating "data" DVDs, but I was thinking more in terms of an "authored" DVD for playback in a courtroom from a commercial DVD player and without a computer—based on your description of the aforementioned "situation." As such, I did a bit more testing...
Files processed in the same manner as your sample file (previously described) could, of course, be authored using iDVD. Unfortunately, when I tried the original source file directly in iDVD and Titanium Toast 11, the audio was lost as before in QT. Fortunately, I also have a copy of iSkysoft iMedia Converter Deluxe installed on this system and tried it. Like VLC and HandBrake, it also supports the "errant" audio and can even author and burn DVDs if needed. Will send you a copy of the DVD image produced from your sample file. (Had to run it twice as I forgot to change the output from NTSC to PAL the first time through.) Authored content in this "imaged" format can be stored on a computer, played directly in apps like VLC, or burned directly to DVD for playback on a commercial DVD/BD device. Here is the URL for the DVDMedia file:
P.S.
By-ythe-by, was your test video taken along the A-16 heading north?

Apr 27, 2015 11:12 PM in response to Jon Walkerby drrbr1,Thank you both for your continued interest in my problem.
In the last couple of days I had come across iSkysoft Creator which as Jon says seems to play the raw files with both video and audio and should output to DVD for playing on a commercial player. Have not done this yet, only output to a video file but Jon's Test Burn would suggest it will be OK. i have played the Test Burn file sent to me OK.
I have only run the trial version so far with watermark but at $49 for the registered basic version it would appear a simple solution for the future. However, ever conscious of the pension pennies I will also look at Drew's free alternatives.
I have learned a great deal from these exchanges - I am most grateful! In this technical world, too frequently I find myself swimming in treacle and often the most difficult part is finding the right question. It is clear I struck lucky with my question this time in that it attracted responses from such knowledgeable respondents able, willing and patient enough to see this through.
Thank you both,
Bob
PS Yes, Jon - it is the A16 heading North! Amazing you should recognise it! I live about 10 miles from Skegness. It's a small world isn't it? If you have a minute I would love to know HOW you recognise ,it!
I wish I could reciprocate, but it is is over 40 years since I was in New Jersey and then only in Newark!

Think nothing of it. Your problem provided the basis for an investigation that was intellectually stimulating and from which I gained new insights.

I suspect iSkysoft is using the same FFmpeg framework that is utilized by the free VLC and HandBrake projects and, as a result, these apps share similar playback or conversion capabilities. There are probably many apps on the market that will serve your needs equally well and it will likely be more a matter of choosing which one best servers your particular needs and/or whose interface is easiest for you to use. I started with the Tube Studio app and later switched to iMedia Converter Deluxe since it incorporates the download capability of Tube Studio with the capabilities of their Video Converter and DVD Creator for Mac apps even though I still use VLC for general playback of files not handled by QT/QL and HandBrake which remains my primary conversion app for BD and DVD content that is managed by iTunes for steamed viewing within or away from home. Most people tend to gravitate to a particular app depending on the specific nature of a given project so it may be a good idea to try several.

You are most welcome. It is always a pleasure to try and assist someone who shares a common interest, as well as, make new friends or acquaintances from around the world and even learn a few new things myself.

Am almost ashamed to clear away the wisps of mystery by admitting it was merely a recognition of the "Surfleet Seas End" and "Sutterton" signs that gave things away. Like you, it has been more than 40 years since I last visited. At that time I was in the USAF and sometimes flew to RAF Mildenhall on "Hog-Nose" (RC-135) aircraft as a "back-ender" (air crewman). Spent most my time in the Cambridge area but did manage to visit London, Southampton, Longleat, Stonehenge, Leeds Castle, etc. Had a friend stationed there who owned a '69 E-Type Jag which, thanks to an international driver's license, I loved nothing more than to drive around the countryside getting lost. Don't believe I ever got as far as Boston or Skegness but I see there is supposed to be a Burger King now at the A16/A17 roundabout. In any event, I have warm memories of those times visiting with people from whom I was "separated by a common language and a common heritage."
Live long and prosper!

Jul 4, 2015 12:30 PM in response to Jon Walkerby Marlene Sanges1,I just noticed this series of posts. I know I'm late to the discussion, but am I missing something here? No, I can't open my .mov files with Quicktime, but I can open practically all of them with iTunes. (I do have a couple stubborn ones that I have to use VLC for.) I click once on the file I want to open and then go to File > Open with > and select iTunes (or VLC).

Jul 4, 2015 4:44 PM in response to Marlene Sanges1by Drew Reece,Marlene Sanges1, it is unclear if you have the same issue & the original poster hasn't replied a far as far as I can tell. There is a lot of info in this thread, please review it for ideas.
I think you may want to create your own thread - there is a lot for people to read here to catch up with the state of each poster & it is getting confusing in my opinion. Post a link to your thread here if you want me or other posters to follow that thread.
I suspect you are being bitten by several different file format issues, but it is very difficult to tell from the info you provided. Please isolate some files & gather more info on them (like the mediainfo or Quicktime player info that has been posted here). You should also try the older version of Quicktime player…
QuickTime Player 7 for Mac OS X v10.6.3 or later
That version supports many older formats, you should consider converting any files that do not play if you want them to work on future OS X versions.
