I am by no means a camera expert but this question and speculative 
answer makes my brain hurt.  I see that the MotionXtra HG-100k is a 
specialty high frame rate CMOS camera which is capable of capturing 
1000 fps.  It is not a normal "high def" camera.  "Standard def" is 
only good for 30 or 60 frames per second.  Presumably you would use a 
high frame rate 35mm film camera if the intention is to capture a high 
frame rate for slow-motion playback.

If the target is standard def, the I would not automatically summarize 
that compression is the limiting factor to quality since people seem 
quite happy with the quality of DVD video.

You will need to define your intentions better before any reasonable 
justments can be made.
