How to deinterlace in FCP?

Still tooling around with FCP to learn it and I need to learn how to deinterlace my stuff now.... How can I do this?

Thanks
 
Easy. Add a de-interlace filter. :)

Select the clip in the timeline then go Effects>Video Filters>Video>De-interlace.

Or you can simply drag the filter on your clips (a load at a time if they are selected) from the Video Filters tab (on the left side of screen normally). I would also drag and drop it into the Favourites Bin if you are going to be using it a lot.

There are some better filters than the built in one avaliable too. Searcg online. Graeme Nattress sells them.
 
Yes, if you do plan on using the Final Cut Pro de-interlace filter, try this. duplicate your footage and lay it directly over the original (so you have 2 tracks with the same footage). Then use the deinterlace filter on the bottom layer and select odd fields in the filter settings. Then add another deinterlace filter on the top layer footage but set the fields to even on that layer. Also, set the opacity of the top layer to 50% so you can see through to the lower layer. Render away.

Although this is more work and rendering is involved, this method should cleanly keep the resolution loss to a minimum as you are employing both interlaced fields in your footage, but still deinterlacing the footage.

Hope you like this method ...
 
Galvan,
Will this method raise the file size once exported to QT being that I would of just doubled the properties within the project?

Also, I'm prepping for a short that I might be shooting next weekend. Are you busy? I know we've been shooting PM's back and forth for a while so maybe you can come by the location.

No, the compression will still be at the same data rate.
 
Thanks mmm for answering .... Coffee, I have to be at the station on Saturday, but I may be free on Sunday ...
 
thanks mmm!

mgalvan, alright so yeah man I'll set things up and keep you posted. hey, do you have a dolly that you'd be willing to bring? I bought all of the materials (no wheels yet) to build one and I might have it built before then but working on my house for sale is taking all of my time. Either way, I'll let you know if Sunday will be the day and the time....

Coffee,

the best way with the least resolution loss is to buy and use Graem Natresses G Film effects.
http://nattress.com/

With a click it will convert 60i to 24p. You can also use it to correct for film gamma, and to add film looks like magic bullet.

It costs $100.
It renders faster than Magic Bullet ( I use both).
Graeme is a member of this forum and when you email their customer service you will get an email back from Graeme, usually the same day.
You also get free software updates for life.

The 24p motion is comparable to the DVX and better than the Sony 24p emulation modes.

If you don't want to go to 24p, you can also go to 30p for a more video deinterlaced look and to 12p for effects like old timey film,

Note that it will be a standard 2:3 pull down so every 3rd (I think) frame will be interlaced in 24p, like standard telecine (you edit in a 29.97 timeline) and this will look right on a tv monitor.

30p will have no interlacing.
 
oh yeah...

oh yeah...

BTW:

G Film only works with origin footage of 60i, it uses teh interlaced fields to do its magic.

If you want no interalcing ay 24p then you should shoot at 24pA and edit on a 23.97 timeline and output to dvd or 24pmeg 4 for the web. This is absolutely no resolution loss and no interlacing.

If you are tring to de-interlace the every theird frame from 24p normal - you shouldn't. the 29.97 video needs that to look right on TV.

If you want to do that anyway, then you can download this plugin:
http://www.perfectlypolitepictures.com/suggests/quicklook
its free for the time being because it's in pre-release.
Set the level off the effect at its lowest and iit will give a higher resolution image with no interlacing.
