I film with sony fx7e pal 1080i
should I deinterlace while capturing with cineform neoscene or not

I am aiming to output to both blue and dvd from a final edit in prem cs3 then master with encore

I am unsure if Interlace is best off from the start to avoid probs

anyone?

thanks alot

People do it both ways. There is no "right" answer.
I would point out that 1080 Blu Ray is natively interlaced. If I were delivering on Blu Ray, I would stay interlaced thru the entire post production chain.

BlurRay is either 24p to 60i, only SD DVD is natively interlaced only.

Quite so. My point only was that if you have shot in 1080i, then it's a straight path to BR delivery.

While I'm using CS4, the flow should work in CS3, as well. I shot HDV with my HC3, and imported the video with NeoScene, retaining the native video format, 1080i. After editing, I exported the video in MPEG2 Blu-Ray format, still retaining the 1440x1080i native video format. On my Core i7 machine, it exported much faster than realtime. I created an Encore project in Blu-Ray format and burned the BD-RE disc. Then I told Encore to Build a DVD, which caused it to transcode the video to DVD format and burn the DVD, without having to make any changes to the Encore project. I call that a real time saver.

Keeping the video in the native format sped up the whole process dramatically, and the Blu-Ray player handled it fine.

Hi John
this is what I was looking for, can you tell me when you exported to 1440x1080i Blu-Ray Format and made your Blu-Ray Disc in Encore, when doing the dvd did you have to alter the field order from Upper to Lower for the DVD Encore or did you leave it as it was?

You definitely should stay in UFF field order. DVDs will play UFF with no problem.
Changing the field order can certainly be done, but it is an unnecessary invitation for problems & artifact.
The conventional wisdom that DVDs must be LFF is simply not true. My projects are nearly all delivered on DVD & BR- all the disks are UFF :)

I let Encore decide what to do when transcoding the DVD version, and it came out great.
