I would say CF 30 strobes way more than 30p on the DVX. How do I get it to look smoother?
Also, Charlie White said that CF gives you progressive footage. Does that mean that it deinterlaces the footage in camera and records it to tape as progressive?

It doesn't necessarily de-interlace -- the jury's still out on what exactly it is that CF30 is doing. It may be doing something as sophisticated as an intelligent de-interlace like DVFilm's Maker software does: only de-interlacing moving segments, and leaving the non-moving sections interlaced (which means that there's no loss of resolution on the non-moving sections). I haven't done enough critical study of CF30 yet to come to any conclusions, but it sure looks at first glance like it's not doing a full raw half-resolution de-interlace.
However, it does look like progressive footage, there aren't interlace comb artifacts in it. So whatever it's doing it's delivering the look of progressive. It is recorded to tape as interlaced. All HDV 1080 is recorded as interlaced.

If by saying "strobey" you're talking about the apparent motion blur then try this: the default shutter speed in CF30 is set to 1/30 so I find that setting it to 1/60 cuts down on the motion blur quite considerably.
If it's something else I don't know what it could be because I've not noticed anything strobey in CF30 so far.

I had asked in another thread if playing with shutter would help this problem. Haven't seen the problem (or the cameras footage for that matter) but I was thinking it might.

It does, at least for me anyway. I think people see the default 1/30 shutter on CF 30 and think the camera is useless for any type of movement. 1/60 has been working fine for me.
