How do I change field order for certain clips?
long story short…
accidentally downconverted some HDV footage and the field order is lower (i believe… i don’t have the project in front of me). It’s mixed with HDV footage from the EX1 (SQ 1080i) which has upper field order (or the other way around… the point is that they are opposite).
The sequence was created in an HDV sequence with the same field order as the EX footage. So… we’ve added some slow motion to the downconverted HDV footage (the footage w/the wrong field order) and although it plays seemlessly before being rendered, when it’s done being rendered, it’s all stuttery. We’ve determined that it’s DEFINITELY a field order problem. We put the downconverted HDV footage in a new sequence made w/the same settings as the footage, add the slow mo, and it renders beautifully.
We’ve tried using the “shift fields” filter on these clips w/no success, as well as just deinterlacing them. Each time the result is the same… stuttery. Is there a plug-in where I can change the field order from upper to lower, etc. or is that what the shift fields filter is supposed to do? Basically I don’t want to have to put this all in another sequence w/the opposite settings as I assume then it will be the EX footage that is messed up. Ho hum.
For what it’s worth, I’m on an 8 core using FCP6. Thanks for any help!

Simply right click on the clip in the timeline and choose Item Properties then change the field dominance from lower to upper.
In the browser you can scroll the the field dominance column and do it there. If you have any clips in the timeline, though, they will not update so you have to do it in the timeline as well.
SD clips are supposed to lower field first unless you are working in PAL SD Uncompressed.
The reason why it looks bad is that what I have seemed to have found, is that FCP wants the field order of all clips to be interpreted the same as the timeline. I have not practiced this across all formats and field orders, but in my editing it seems to be true most of the time.

Julie,
I’m not sure I completely understand what you’re doing, but I can tell you from my own experience, that if i copy and paste an EX-XDCAM sequence (upper field 1st) into a DV timeline (lower field first), FCP will convert all the EX footage to match the field order of the DV sequence EXCEPT the slo-mo clips, so everything will look fine except the slo-mo. The only way I’ve found around the problem so far is to either export a self-contained Quicktime movie of the EX sequence and drop that into the DV sequence OR make separate Quicktime movies of all the slo-mo clips and replace the originals in the DV timeline with the QT movies. I’m not sure this applies in your case, but I believe the slo-mo clips are the culprits.
Hope this helps.
