Deinterlacing Quicktime Movies

Hi everyone. Got a quick question here I hope I can get some help with. I have a timeline of a finished project with multiple layers of video and graphics. It is a 1440x1080i project. I would like to make two quicktime files of the project... and imort them into a seperate sequence. One of the movies I will use as my base layer and the 2nd copy I will overlay to add saturation as a composite layer.
QUESTION: Is it possible to make the Quicktime movies and deinterlace at that juncture...or is it necessary for me to de-interlace prior to making the Quicktime movie files?

Hi Dave,
Thanks for taking the time to help me out. I use a Sony HDRFX-1. It employs the 'Interlace Scanning' method. I have always needed to de-interlace in the past. I will say this though: I previously have log and captured at 720x480. This Project is one of the first times I have log and captured at the higher def. size (1440x1080i). Is there any correlation with the step up in resolution which does not require de-interlacing?

If you shoot progressive-scan video, there really isn't any need to deinterlace. You simply set the field order -- erroneously referred to in FCP as field dominance -- to none.
Poof! Done! No resolution-robbing deintrerlacing needed!

Hey Dave,
Thanks for getting back to me so quickly. I tried to do a little research on my own before posting this response to avoid wasting your time. Appreciate you helping out.
Do you happen to know what the default settings for scanning are for the HDRFX-1 when no cineframe (picture profile) has been selected? I was trying to discover it on my own and could not. I am guessing, as you suggested, that the camera was in progressive mode when I was shooting the footage.
Could you also direct me to the tab in FC that lets me select the 'field order'? Will it have to be chosen for each clip? If this is the case, can I do as I originally wanted, which is make a Quicktime movie first and then just set the order/dominance one time? I am hoping to same some rendering time this way.
I guess the real insurance in making sure I did everything right is to burn a test DVD and see what it looks like on a TV/monitor.

Hey Dave,
I went into the 'Sequence' tab and changed the 'dominance' form 'odd' to 'none'. Immediately the entire time line (video and audio) went to RED render band. I understand why, but am wondering if this render procedure will be a one time process notwithstanding future edits I will make and if the shift in fields will effect any editing I have already executed. In other words is there a benefit to changing the field 'order' prior to editing?
By not having to de-interlace, you assert that I should (in theory) have better/cleaner results when I add my composite layer 'overlay' to pump up the darks and the mids. Is that a correct assumption?

You need to read what I wrote carefully: you need to shoot progressive scan FIRST. Jeremy has the details on what you need to do right now.

Check that Dave, the RED render bar deployed on the video side only. I was looking at a blown up portion of the timeline when I erroneously reported that both video AND audio were effected.

Hi Dave,
The status window suggests a 4 hour rendering period. I know that it is usually always much shorter than that as the mac and FCP expedite through the task, but it still seems it will take a good half hour or so. The data is only :30. Although it is hi def, does this sound like a normal time estimate for such a procedure?
I do have quite a bit of layers and graphics (which is why I wanted to quicktime movie the project as soon as possible).

Hey Jeremy,
In other words, do I have to go into FC and apply de-interlace to each individual clip?....or can I make a quicktime movie and apply 'de-interlace' to the single quicktime movie? Thanks for your time man.

It depends. If you use a plug in, it's every clip, if you use compressor, it's a whole movie.

HI Jeremy,
I may not be making myself clear. Within Final Cut, and after selecting 'in and out' points, I select FILE>EXPORT>QUICKTIME MOVIE. After this file is created it bears a FC icon and is only recognizable by Final Cut (unless converted). These movie files are generally very large files and I am assuming uncompressed. Let me know if I am good up this point.
If I decide to use compressor, what codec should I use? 8-bit, or 10-bit uncompressed? The main thing here is that I end up with a file that I can layer on itself with some effects and that can also be de-interlaced as well.

Hey Jeremy,
So if I make the QUICKTIME movie and deselect 'Make move self contained', am I essentially making a mirror copy with all of the original attributes albeit a single clip? And at this point I can deinterlace the single movie length clip?

No, it is a small reference movie that references the media already on your scratch drive.
You bring that reference movie in to compressor. When you deinterlace, it will make a whole new self conatined movie, then you bring that new movie back in to FCP.

Generally, I like to deinterlace my footage for the web at 720p when I shoot 1080i. I also do this for DVD's - pointless, I know, but oh well.
What is the best way to deinterlace? Using Compressor? The Deinterlace filter in FCP? For compressor, if you select to Deinterlace in the Frame Controls (leave field dominance as Original), then I'll ahve about 45 hour remaining. Is this normal? I see this as being slightly ridiculous.
Is there any easier and/or more effective way (for both time and quality)?
Re: Deinterlacing Quicktime Movies by Ryan Atkins on Nov 6, 2009 at 6:33:05 pm
Well, then I assume when I select it to Deinterlace and leave Field Dominance as Original, that means the time I have left is actual and i just need to wait?
Has anyone noticed any major quality differences by not deinterlacing for the web?

If you've shot a snail race or the movement of a glacier, you should be just fine. Anything with any kind of real motion in it will reveal the interlacing.

Well, i haven't yet been able to shoot grass growing or a snail race, so I guess I should just keep happy with my current quality or wait at least 15 hours.
