how do I deal with .thm files and iMovie?

I've been using my digital camera to take short movies. When I download them onto my computer they show up as a file with a name like: MOV02161.MOV and another with an identical name but the extension .THM. When I double-click on the .mov file it opens in Quicktime and plays back no problem. When I import the .mov file into iMovie it plays without sound. I've noticed that the .thm file seems to be crucial to whether there is sound or not (I tried trashing one but then the Quicktime video played without sound!) but I can't import the .thm files into iMovie. Do I have to convert them to some other format? How do I do that?

kstp,

the .thm file is simply a jpeg thumbnail version of your movie which you could probably view by changing the name from .thm to .jpeg (not entirely sure about that). Your audio problem is more likely caused by iMovie not having the codec needed to play the audio format encoded into your mov container. Maybe someone here more familiar with iMovie can tell you what audio formats work within iMovie, and you can set that in your camera to prevent this problem.

Now, worst case scenario is that you'll probably have to extract the audio and convert it to something that works in iMovie. You can extract the audio from within iMovie from the advanced options menu. You can also use a free app called FFMpegX to extract and convert it to something else. Hopefully though, someone here will have a more convenient solution for you.
