Major interlace artifacts in 24p normal project

[Stas_Tagios]

Hey all,

Cutting a project shot in F5 mode (24p normal), on a 60i timeline, captured as normal NTSC dv. The interlace motion artifacts are quite evident and distracting on my NTSC monitor and on any subsequent DVD burns played back on my regular tv.

Everything else I've shot with the DVX was a F6, so no such problems before. I've also shot and cut plenty of 60i NTSC video and never experienced such evident artifacting. I'm assuming I've got some sequence setting or something set incorrectly, but can't figure out what.

Don't particularly want to have to run all the footage through cinema tools to remove the 2:3 pulldown; I'd rather keep the material in 60i. Is there even a way to just remove the 2:3 pulldown from an edited sequence rather than all the associated footage?

Sequence is set to NTSC DV, 29.97, lower field dominance.

I can post pictures of the artifacting if it helps.

Not sure why artifacting would be worse than 60i. You have 24 progressive images and the camera is adding standard pulldown so that some frames are split and merged as odd and even fields. This is the exact process that happens to movies shot on film and transferred to video.
The one thing is that 24fps is a slower speed so if you have fast action there will be more of an offset between the odd and even field images than if you had shot at 60i. But once again it shouldn't be any worse than movies you see. You might want to check your shutter settings and make sure F5 is still set for the default 24p mode.

You can't easily remove pulldown from an edited sequence since you may have cut on a field boundary. This means the cadence (the 2:3 frames) is not consistent and even if it could sort it out you may end up with only odd fields (or even) of a particular frame. (i.e. every other line woudl be black since the orginal frame is no longer available).
