I get "interlaced" artifacts from 1080p footage

This footage wasn't shot on 1080pA, it was shot on regular 1080p.

I have burned a DVD and even watching it on 1080i on my television I can see interlaced artifacts whenever there is movement.

Is there a setting on Compressor to remove this once I convert it to DVD or other formats?

Please help me, I've tried everything.
 
did you remove the pulldown when you imported? My guess is no, so you still have interlaced frames in the footage. 108024P is recorded in an interlaced format on these cameras. To edit/watch the progressive frames only, you have to remove the pull down when you import the clips. Always use the 108024PA, it only records the progressive frames, and doesn't record the interlaced frames. Giving you more recording time, and less post time.
 
I used the default Log & Transfer settings. I'm almost certain that the remove advance pulldown and duplicate frames box was set to positive.

Isn't there any option now when I need to export?

How come I see the artifacts even on an interlaced TV?

It makes sense to see it on a computer monitor, but even on an interlaced TV?

Is there a Compressor setting that works well this HVX/HPX footage shot at this format?

Look at what you have...start with your raw. Does it look interlaced? If no, move to the next step...whatever you use to edit. Does that output look interlaced?
Move on to the dvd burning software. If all is well up to that point, take a hard look at all the settings for burning. It's like having someone else proof read for
you. Stuff is easy to miss when you are alone.
 
Thomas. Go back and reread what I wrote you. You imported the footage wrong (Not your fault all the time.) This camera records progressive frames in an interlaced format, depending on your version (version 5 I believe not certain) of final cut, the remove pulldown can be buggy on importing 1080P footage from the original HVX200.

Here's what I would do. If you see progressive lines on your computer monitor, you need to start over. You never got rid of the interlaced frames, this could be from a bug in FCP or from you failing to remove pulldown. Make a new project, and log and transfer the footage again double checking that you wanted to remove pulldown. Then in FCP look at your clips individually and see if you still have interlaced frames. Go through every single clip and check for interlaced artifacts. They will not be there in every frame, so be sure you are thorough. If you do see interlaced lines in every frame of your footage check your sequence settings, and make sure you are setup properly for 1080P.

For every clip that still has interlaced frames, you need to isolate, and run them through cinema tools, which will properly remove the pulldown however it takes a little time. There should be no interlaced lines left when you are done with this. The last places I would look are the settings of your export and DVD authoring, most of the time (unless you specifically specified otherwise) Exporting and DVD settings will be based on your sequence settings. If you can post your footage somewhere I'll be happy to check it out. But the advice I'm giving you is based entirley upon personal experience, I looked everywhere, and tried everything before someone told me about FCP having a bug and to use Cinema Tools on the clips. Solved my problems immediately. And I shoot 108024PA or 720PN now without exception.
 
I'm not trying to be pedantic, and hope this works out for you, but please always check those L/T preferences settings before starting the process.

We see a bunch of issues when people don't.

Again, hope this can be resolved. Good luck, and also good to always shoot 1080 24pA.
