Hi, thanks for your replies.

I did defrag and when it exported this time the output was smiles better , the slow motion whilst not perfect in harmony is not as jumpy as previous. I notice that where the slow motion is involving the camera panning a little and the subject moving there is some jumpiness there. Is there anything in this clip settings you think could help that particular scene??



...or have I got everything slow motion friendly accounted for there??


These are the default settings I'm using when exporting the movie.





In the last one (Keyframe and Rendering) I have other rendering options like; No Fields (progressive scan), and Upper Fields First, and as you can see there's the option to Deinterlace Video Footage...but I'm not sure what all of them mean, and weather they will help the slow motion bits of the video??

...I am just nitpicking a little now though, because like I said the output AVI file is miles smoother better than before, maybe I should go ahead and covert to MPEG2 now??

The bitrate of the AVI file is 1536kbps, I'm just wondering if my old GeForce 2MX Graphics Card is not powerfull enough to play it back smoothly?
