Ive been scheduling this shoot for quite some time and for some retarded reason I set the detail level in the scene files to +3. There are interlacing artifacts all over the footage and it's horrible. anyone know how to fix that in post?? Flicker filter helps a bit but not as much as I'd like. thanks.

Ryan,

The detail setting doesn't effect interlacing, only sharpening. Which scene file did you shoot with? F5 and F6 are the 24p presets. If you shot with those and still see interlacing on certain frames, that is the 2:3 or 2:3:3:2 pulldown. That is normal, and your NLE should remove it if you use the right project settings.

yeah i shot f6 24pa. i know that some artifacts are normal but im getting them all over the frame. it makes it look horribly electronic.
 
Go read about 24pA ("Advanced"). It's not intended for playback. You need to use your editing program to remove the extra frames to get to the original 24 frames per second.

You'll need to post a frame grab for us to examine.

My hunch is that most people decrease the Detail settings, not increase them. Decrease for more of a film-like look, increase for more of a video-look.
 
Check your V Freq Detail. Is it on "THIN"? This will often produce flickering on a TV and stair-step artifacts on diagonal lines which could appear to be interlacing artifacts.
 
David Jimerson, I think you are correct. Here is a still of what is going on. this only occurs every 5 frames or so because of the 24pa pulldown.

The dvx book says to shoot in THIN V Detail because artifacts wont show up on lcd displays or computor monitors. But it sure does on my computor monitor. Anyone have any suggestions to how I can get rid of the artifacts.

I'm aware that I can remove the pulldown during capturing and edit on a 24p timeline but I don't know what I would do with the project when it's done. I could display it over the web but that's about it right? Thanks guys.

Ryan,

Yes, if you only see it every 5 frames, it is the normal 24p Advanced pulldown sequence. The intent with that mode is that you edit on a 24p timeline. Your NLE will drop the frame with the interlacing, so you should never see it. If you edit on a 60i timeline, you will see it, which is probably what is going on.

You ask a good question about if you remove it, then what do you do with it then. The answer is that when you export, it gets added back. Again, it doesnt' matter because you'll never see it on a TV screen. It is a computer phenomenon.

Let's examine a couple of scenarios.

1. If you want to export a file to import into another editing program (back into Premiere, After Effects), then you export back to 24pA. The drop frames will be added back, but then removed again when you re-import it.

2. If you want to export a file to actually display on a TV, then export to 24p Normal 2:3 pulldown. There will be lots of pulldown frames, but they will not show on TV.

3. If you want a pure 24p DVD, you can export to DVD straight from Premiere.

Bottom line, no need to be concerned about the pulldown. If you see it, you are working in the wrong kind of timeline and need to adjust. It may pop up again from time to time, and it's always a matter of configuring your program to recognize the footage correctly.
 
Well, it's also possible to export a 24p file with no pulldown which can be used in Premiere or After Effects. You'll need to reinsert pulldown if you want to go to DV or print back to tape, but if you can transmit the file in another way, like on hard disc or optical disc, then you don't need to go through those extra steps.
