Deinterlacing Quicktime Movies

[Jared Cicon]

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 720×480. 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?

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.

Thanks Dave.

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?

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).

Sorry, but changing the field dominance to none does not deinterlace the sequence. Cancel your render.

Also, why make two movies, why not just double the movie up?

You should use compressor for free or use a third party plug in such as Fields Kit or Nattress.

Hey Jeremy,
Thanks for helping out here. Could you read my initial post and let me know what you think? Thanks.

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.
