How is the quality in Movie mode Details please for Fuji F20?

Details please for Movie mode only on the F20 (cause the one in the Nikon L11 I had wasnt good)

You have to understand that at best, movie mode is an add on feature. It still has to use the same chip and lens as the still camera and the camera is first and foremost a still camera.

The Movie mode is a standard at 640 x 480 at 30 fps, or you can shoot at a smaller web quality 320 x 240. The thing is that the encoder that it uses (and I suspect the Nkon had the same) is Motion JPEG. Not the best, but it's pretty standard. It also has mono sound. So in the end, I think you'll end up with similar quality.

And one thing to watch out for though is that most digital cameras will not allow you to zoom, or if you do, it'll cut off the sound. Just be sure about that.

Oh do you know which is better than Motion jpg?

Well Sorenson is a good encoder. But I don't know of any digital camera that uses it. However, if the camera shoots in avi (and some do), then it wont' be encoded in motion jpeg. that's usually a quicktime issue.

AVI is just a 'container' program for video and sound so MJPEG is used with AVI or Quicktime.
Motion JPEG is the most common type of encoding for digicam movies and it can produce good results if well implemented. The disadvantage is the amount of memory space on the card it uses up. Some manufacturers eg Casio use MPEG4 which is much more memory efficient as it compresses both the individual frames and the motion. A newer version is H264 which is even more efficient. If well implemented, MPEG4 works well and uses much less card space but it can look worse than MJPEG on some cameras. (eg 'blocky' with motion). I have cameras that use both methods.
I would always go for the camera that gives the best still images and look at movie quality 2nd.
BTW, my new Fuji S5700 superzoom does a good job of MJPEG movies AND it does use the 10x OPTICAL ZOOM with sound.
