  1. I recently found out that a few of my Quicktime .MOV video clip files (taken with a Canon S90 compact camera) didn't work. When double-clicking on my Mac, Quicktime Player will launch but tell me that the file isn't recognized/is damaged. However, if I open up the same file in VLC it plays perfectly with both audio and video.

    I then assume something minor is damaged and can possibly be repaired without too much effort, but I haven't found any solutions so far apart from a service called AeroQuartet. It'll cost me a fair amount of money, but the preliminary results of analyzing my files tells me that they can do it.
    However, I was wondering if someone here knows of methods I can try myself first before parting with my cash?
    I'm on an Intel dual core iMac running Snow Leopard 10.6.6.

    Use Vlc transcode abilities to convert playable files
    1. In VLC, go to "Media >> Convert / Save..." (Ctrl+R).
    2. Add the input file(s) or stream(s) you want to transcode. Press "Convert / Save".
    3. In the "Convert" windows specify the destination file name (including file extension - e.g. on Windows "C:\out.mp3").
    4. Select the desired codec from the profile list. To check/edit the settings of a given profile press the "Edit selected profile" button. Profiles can also be added/deleted.
    5. Press "Start".
    If the profile settings were compatible and transcoding was sucessful a playable destination file should be created.

    Should it work you no longer need to shell out any money to that company.

    I couldn't find any "Media" menu in VLC (perhaps the Mac version is different) but I have been trying the File-Streaming/Export wizard. It actually worked very well except for the fact that audio was completely missing
    From what I've been told, there are some limitations in VLC that causes this.

    Jagabo: I'll download and give AviDemux a go!

    Any ideas anyone as to why my files are playable in VLC while QuickTime player completely refuses to open them?

  5. Nope, AviDeMux fails to open the MOV files in question
    Any other software I can try?

  6. Check your MOV files with MediaInfo to verify that they are really MOV files.

    Well, it's apparently recognized as a video file:

    But compared to a fully working MOV file from the same camera, the above doesn't contain much additional info:

    Remux to a mp4 wih ffmpeg, from a command prompt:
    Code:
    ffmpeg -i video.mov -vcodec copy -acodec copy output.mp4
    Or try mpeg streamclip, but I guess it will reconvert the video.
