I'm a macos user, using a utility called Snapz Pro X or another called iShowU.

Basically you can capture whatever happens in your screen to a movie file. 

In poser i set Tracking to FUll.  If i dont have the movie capture utility recording, using the Poser Cam control sphere is smooth but if i start recording movement starts getting choppy. 

Is there a way or another utility to use so that everything remains smooth?

i'm on macos x tiger

You'll need to reduce the size of the video capture settings in both dimension and fps.  The video capture is heavily cpu-intensive and will interfer when capturing another application that is cpu intensive.  There is support information concerning this in the manual:

On the machine side, reduce your monitor resolution, and capture the smallest area of the screen as possible. Quit as many other applications as you can as they use up extra CPU cycles. On the Snapz Pro X 2 side, reduce the framerate, deselect all of the audio options, and select Fixed Camera.

Optimizing video recording is explained more in the Snapz Pro X 2 Manual in the section called, "Getting the Smoothest Video Possible".

the best screen capture program by far is windows media encoder and it's a free download from microsoft. it's pro quality, used commercially and efficiently takes advantage of 64bit and multi-core cpu's. it can also be programmed using standard languages or even windows script such as javascript.

if you are using poser, it will not slow down the interface if you have multi cores and enough clock speed. you can even narrate it as you go. it's a great tool for documentation.

it takes a bit of time to learn about it, but there is incredible documentation and sample code online if you wish to program it. it does live video capture from video cameras or tv tuners and live streaming or recording and will convert video or audio to alternate rates and sizes.

way more is possible than i have mentioned if you want to make the effort. i have an application that streams my tv tuner on the web and the remote user can even change the channel. there is a delay of about 20 seconds to see the new channel content due to the latency of streaming.

But this is MAC OS !!!! ;)

please excuse me. i'm sorry. i haven't owned an apple computer for a while. i didn't imagine someone was talking about a mac. from television i understand that the mac "just works" and it also makes you thin and cool.

Wel you didn't read his post very well then. The very last line states he was using "macos x tiger" which even I in my PC only newbness knew to be Mac OS 10 Tiger.

I also mis read that I thought he was talking about another program LOL, "macros" is what I read

Yeah the first time I thought he misspelled Macro's but when he did it again and said macos X tiger I remembered a Mac OS called Tiger and got the reference.
