Is It Possible To Edit 30P Progressive W/O Interlace in SD
Hi Friends,
I’m trying to scale and color some progressive de-interlaced files that need to end up streaming on the web. The files are de-interlaced progressive format Photo JPGs 720 x 480. I want to maintain the best possible image quality, so I don’t want to re-interlace them and then have to de-interlace again.Is there any way to work with progressive format in the FCP timeline without re-interlacing?–i.e. without re-interlacing them on the import and then re-encoding to progressive on the export?
Best Wishes and Thanks,

Progressive timeline is when the field dominance is set to NONE.

In and exported with out interlacing?
At what stage does it get interlaced so it can be seen on the NTSC program monitor?
Thanks a bunch. -
Hi Paul,
In FC make sure that your footage appear n the Browser with “NONE” as the field order.
As Michael points, edit in a NONE sequence.
Even if the movie is played as interlaced, will keep looking Progressive because there is no motion difference between the two fields. They have been shoot at the same time.

Thanks, but the question is whether FC is re-interlacing the image or not. I understand that both field would be the same so that it would “look” progressive. But does it stay a true progressive file in and out?
Thanks for your input.

If the sequence is progressive (NONE) the movie will be fully progressive.
If you put animated titles on top, they will be rendered as progressive.
No interlacing artifacts at all. No Motion difference between the fields.[Paul Blin] ” the question is whether FC is re-interlacing the image or not.”
FC can not Re-interlace. Re-interlaceing means to build two different (in time) fields from a single frame.
You can do that only with certain plugins or in Compressor.

Hi Dave, fantastic! I just wanted to be clear. Thanks so much.
Yes the files are for the web. They are important spots I did in Asia and the Digi Beta masters were lost. All we have are DVDs from the production company. We carefully extracted the data from those DVDs and several of those files were mastered to the DVDs in Progressive format (verified by Inspector). This is probably due to the fact that I originally shot these spots in PAL 25FPS on 35mm.
I need to punch up the color and lose the blanking on a few of these progressive QTs. I understand difference between progressive and interlaced. I know the file has to be interlaced to even be seen on a program monitor. I was just making sure the Sequence wasn’t re-interlacing them (in the render) and then de-interlacing them on the export. Because that’s similar to how Avid handles imported progressives at 30P.
We are looking for “transparent” in and out of progressive files and according to you, we’ve found it. Thank you for your expertise.
Best Regards,
Paul
