Canon G9 movies don't play after transfer

The movies I record on my G9 play back just fine on the camera. However, after I transfer them to my computer (Apple iMac G5, OSX 10.4.11), the play back video + audio lasts for just 1 second and then ends.

The AVI files appear to have transferred fully, with the file sizes on the the computer varying based on the length of the movie (~10MB up to ~200MB). But regardless of their size, they all play for just 1 second.

I've tried playing them using Canon's Image Browser, Apple's QuickTime, or iMovie, and I've tried transferring them via the camera or via a SD card reader. All with the same result.

Any ideas of what might be going on?

of audio or video streams - it's all to do with how the file is encoded. I suggest that you take a look at VLC, which is a free download, and usually solves most of these problems.

Your camera saves movie in the m-jpeg format

these two sites mention quicktime preferences-advanced-show legacy encoders, whether that will work.

Thanks for the info. VLC media play was indeed able to play my videos (though somewhat choppily). VLC reports an AVI index error when I point it at any of my movies created by the G9. It is able to repair the error to enable playback. But I was not able to get VLC to write a fixed version of a movie which I could then play using Quicktime.

The Quicktime "show legacy encoders" option is only for allowing exporting using older codecs. Turning that on did not enable my G9 movies to be played by Quicktime.

The error report by VLC seems to suggest that the reason why Quicktime cannot play them is not due to lack of support for a particular codec, but rather to a glitch in the writing or transferring of the video files by my camera (it's a factory refurbished model, so maybe it has some issues).

I'm going to give Canon a call about this and see what they say. I'll report back.
