>Sorry about the slow pace of the reply but I have been shooting and also perusing some ideas to solve this although they have all ran into a brick wall. Yes I assume the problem is "reversed field order" I have set lower field dominance in both the sequence and clip settings (PAL DV Project). Strangely only affects some clips and not others.
>One clip even changes half way from fine to jerky. On the TV monitor playing the troubled clips the movement looks only a little strange but if I freeze frame on movement it judders. When I burn a DVD (FCP-compressor) movement on these clips look weird with jagged tearing on the movement.
>I can deinterlace the clips and solve the problem but a bit drastic. Do you need any other information? Can I reverse the fields back?

>I noticed that. Somewhere in the video-filters, you'll find a anti-flicker filter, which you can apply to the flickering clip (it has 5 settings).

>Given that you set your project to lower-field dominance, reversing them should not be the thing to do. But again in the video-filters, there should be a filter to reverse the field-dominance.
>The problem with FCP and field order is that in PAL SDI and analogue land, our field dominance is UPPER. While in PAL 'DV' (DV25, DV50, DV100 etc) land, our field dominance is LOWER. DeckLink cards (I've got both a Pro and an SP) perform on the fly conversion from DV to 8bit UC and flip the field order. If you've captured via SDI and converted to DV, you'll get similar problems.
>Which doesn't solve your problem(s). It could quite simply be an issue with that particular image...or with your settings (Compressor on 'auto' field detect). Flicker filter in FCP works well, or you can use FieldsKit or, if you're willing to wait a LONG time (and pay), get someone to run it through Magic Bullet.
>If you like, forward me a still from your reel and I'll look at it and determine if its any particular issue with that shot.
