shifting fields
i have been rendering files out of AE 5.5 and importing into FCP 5.1.4 for mastering and have noticed some strange field behaviour.
i am rendering out of AE with best settings, full res, field render (lower field first), QTime movie, animation codec, 25 frames.
when i get this movie file into FCP, it interprets it as upper field dominant and automoatically puts a ‘Shift Fields’ filter on the clip.
the movie file from AE is not upper field dominant. i can see this because when i play it back in my lower field dominant timeline, it looks fine. when the shift fields filter is on, it is jittering and obviously not playing back in correct field order.
why is FCP interpereting this footage in this way? any suggestions?
thanks in advance.

Don’t warry. To set the proper field-order, first take the clip away from the time-line (or at least take away the “Shift fields” filter).
Them go to the Brownser> Select the clip> Go to the columm “Field Dominance” (or “Field order” don’t remember)>Left-click (or Control-clic)> Select the proper Field order.
When ever you inport something to FC you should have a look to the “Field Order” and”Aspect ratio” FC don’t know when the footage is Annamorphic unless you tell him.

[alexus71] “i am rendering out of AE with best settings, full res, field render (lower field first), QTime movie, animation codec, 25 frames.”
25 frames is generally a PAL format which is upper field first. So FCP must be interpreting your footage as Upper Field when you bring it in.
Why are you editing in 25 frames lower field? Are you working with some off frame rate in NTSC?

[walter biscardi] “25 frames is generally a PAL format which is upper field first.”
Walter, in PAL-land we’ve got the disgrace of having some codecs (DV, DVCPro25, DVCPro50..) “lower-first” and other codecs (8/10b Unc..) “Upper-first”.
When you import those kind of footage to FC, the application set the field order as I mentioned. When you import Animation, FC set “Upper-first”. If you export a graphic from AE to set in a for example DVCPro50 sequence is better to export it Lower-firs, so you don’t have to “shift-fields” in FC. However you have to be careful and change the ‘field order” in the Brownser because 100% FC will set it “Upper-first”.

thanks Walter,
a lot of the footage used in the comp is mini DV, which is lower field dominant. so that’s why i exported the animation from AE this way. Just wanted to keep it all the same, so i didnt end up with a field order mess in my final comp.
