Audio from Casio Exilim camera

[a1s2d3f4]

I accidentally shot video using my Casio Exilim EX-ZR100 camera to a slow card (I usually use speed 6x SDHC card, and this one was 4x). As the result, I got an MOV recording that had "buffer issues", where the data output by the camera's encoding module couldn't get written to the card fast enough. So, the video stutters at times (with duplicate frames).
More importantly, the audio seems to disappear after a certain point (3 minutes in a 14 minute video file).

I have a feeling that the audio is still there, but somehow something in the MOV container is saying that it is only "3 minutes long", and so any program that I have tried to extract audio extract those 3 minutes only.

Can anyone recommend what I could try to get to the bottom of this? Is it true that these Casio cameras simply stop encoding audio if a "buffer problem" arises, like in my case, or is it that they simply don't create a good MOV header?

What does MediaInfo say about your .MOV contained file?

What does MediaInfo say about your .MOV contained file?


If I open it in VirtualDub, using a plug-in by fccHandler (I believe), and then look at File Information there, it mentions 3mins for the duration, while the video is, as I mentioned, 14 mins.
Same if I use AviDemux to look at it.

I don't actually see a separate audio duration entry in the MediaInfo for any other player that I have.

But they are not trying to look for "hidden audio", but rather just looking at the header info in the mov.

Any ideas how to "look for" those?

With respect... You have not answered my question. You have not posted a MediaInfo report file (in full)...

@SeeMoreDigital: So, is this the report you wanted?

Hi, might anyone else have any ideas about how I could look "inside" the MOV file bytes, and scan for all possible audio data? I am getting the feeling that all the programs out there are only looking at the header and if it says that there are only 3m16s of audio in the file, it doesn't bother scanning any further.
