Jerkiness in F6 footage

I'm finding that there is some significant jerkiness in a lot of the f6 footage I've shot (particularly in pans, even if they are slow) and have heard that it is not as prevalent in f5. I understand that this has to do with the pulldown frame structure.

I haven't used f5 extensively and want to know what others have experienced.

Thanks
 
Re: Jerkiness in F6 footage

Are you viewing this after advanced pulldown removal?
Are you viewing this directly from DVX?

F6 adds a duplicate frame to do the speed conversion of 23.98 to 29.97 so ti will look jerkier.

F5 blends frames together (using fields) just like a film that has been telecined so it should look smoother.

If you take your 24pa footage and convert to 23.98 then it shoudl playback smoothly (assuming you add telecine pulldown when going out to normal video)
 
Re: Jerkiness in F6 footage

There's really not much difference between F5 and F6, as far as motion rendering is concerned. F5 has 3 pure frames and two blended frames per 5-frame group, F6 has 4 pure frames and one blended frame per 5-frame group. So F5 should be a little smoother, but not dramatically so. As Scott intimates, the playback on the DVX's LCD is much jerkier than when the footage is viewed on a television.

Be sure to watch it on an interlaced TV though.

Sometimes you just forget to check the obvious. The jerkiness was not in the original and I discovered that the footage was incorrectly intrepreted. I re-interpreted it and the stuttering disappeared.

Thanks for the help :D
