Field dominance issue …Shane?

Hmmm… I’m not sure. I’ll check all the menu settings on the camera.

I see you are still in PowerPC. It might take a while, yes, but your field order won’t be screwed.

Yeah… I’m asking Santa for a new Mac 🙂
I’ll post back with results tomorrow. Thanks for your help

There is no reason to make a separate IMX sequence. As your field issues are OK in the uncompressed, make a self contained Quicktime and go straight to Compressor as Jeremy has said.

Alternatively, just import the uncompressed into an IMX sequence as the field order will be baked into the uncompressed file. Although this is a case for nesting, I suggest an uncompressed file is better for many reasons, especially going to Compressor.

For whoever is interested I worked out a fix ad learned some stuff in the meantime (I am in PAL land):

First: DVCPro50 is lower field dominance while the uncompressed material from Digital Beta is upper. When working in the uncompressed sequence, FCP rightly automatically adds a shift field filter to the P2 shots and up to here all is fine.

When I cut and pasted the sequence into a new sequence with different settings – in my case IMX50 to output using the MXF4mac GC Export plugin – those shift field filters on ALL the P2 clips simply vanished creating a playback issue showing up only on the P2 clips.

So, I deduced that this is a bug within FCP. In a sense FCP “sees” the uncompressed sequence as upper and when you cut and past the entire sequence FCP automatically removes the shift field filter on those DVCPro50 clips.

My fix:

Instead of copy and pasting the sequence into a new sequence with IMX50 settings, I DUPLICATED the uncompressed sequence and changed the sequence settings in the new sequence to IMX50 and the shift field filter stayed put on the DV clips. I exported a section of the new sequence and it looks OK.

A quirky problem that only occurs in mixed format timelines I guess. Is it work reporting to Apple?

Thank to all for your time yesterday.
