NS-DV720P insignia videos won't work on final cut express

It basically means you computer needs to understand the language that the files from your camera speak. At the moment they're not talking.

Can you outline the details regarding the type of files your camera produces? Refer to the camera manual.

Often times a third party application to transcode the files will do the trick. Unless we know the details is only a guessing game.

After a quick search I found your camera produces AVI H.264 files and it's going to need transcoding to AIC.(Apple Intermediate Codec)

See if this will do it:

This means Sreamclip cannot handle the clips.
You will have to shop around and find a third party app that can transcode the files from your camera to AIC or DV if you wish to edit in FCE.
