Deinterlacing

I know that this has probably been answered, but I figured we could make this post a place for everyone to place their best methods and experiences with deinterlacing. Anyone know a way to go from 30i to 24p as fast and as good of results as DVfilm? I don't have $150 bucks for it :-/

Since you already have After Effects (listed in your profile), try this method:

AVIsynth

There's a bunch of deinterlacers out there for AVIsynth that deinterlaces just as good as DVFilm Maker. AVIsynth is a frameserver program with a lot of filters that you might find in professional products and it's free!

I've tried the After Effects method to deinterlace but personally I don't think it looks that good compared to other methods.

I agree with Kin Kwan. Try the following filters to deinterlace for AVISynth:

MVBob() - GREAT quality! Just takes a while to render, this is a motion compensated deinterlacer to deinterlace 60i to 60p.

TDeint() - This is a deinterlacer I use, it is great for deinterlacing at higher speeds and still yields great quality. MVBob() uses this deinterlacer as a base deinterlacing method.

Procoder 2 has a very nice de-interlacer. It's fast too.

It's adaptive, meaning I think it searches for only movement.

Fast and top quality. Their DV encoder is awesome too.

Procoder 2 supports 1080i.
Can MVBob() and TDeint() also use the Z1 footage?

It says nothing about 24p though. Unless you manually change the frame rate to 23.976 somewhere.

>> "It says nothing about 24p though. Unless you manually change the frame rate to 23.976 somewhere."

You can create your own target presets in Procoder. For instance, I created a preset under the System section for output to QuickTime using the BlackMagic codec (which I installed separately) in which I set the frame rate to "23.976" and interlacing to "Non-Interlaced (Progressive)". The same options are not available for every target type.

If creating an MPEG2 file using the standard Procoder presets, you can change the framerate to use 3:2 pulldown (providing the source is progressive) and then create a 24P DVD that plays at 23.976 on a computer or progressive scan monitor and at 29.97 on a standard television.

Procoder is really quite a versatile program (though I personally use DVFilm Maker for deinterlacing because I like the options it offers).

AVISynth isn't resolution or file dependant. You can import any type of file you want into it and use the same filters. Only downside would be some filters only support certain color spaces.

Personally I use FieldDeinterlace.

Not only does it deinterlace well, Avisynth has an anti-aliasing filter that you can use to remove the jaggies caused by deinterlacing. :]

Another avisynth vote here. The fact that there are lots of different deinterlacers gives you freedom to try different things in different situations. They are all (mostly) tweakable through their parameters allowing further situation-specific work.

I tried a ton and still prefer TDeint() followed by TDIsophate() (which is the 'jaggies remover') mentioned here. I also use the MV stuff for going from 60i/60p down to 24p with fairly realistic motion blur.

Avisynth rules.

It does have a bit of a learning curve though. No GUI. Script only.

Jonathon,

Can you direct me to where I can see this TDIsophate()?

Thanks,
Josh

Well, I was off by a letter or two...

http://bengal.missouri.edu/~kes25c/

The filter's name is: "TIsophote"

After a deinterlace (with something like his TDeint), you can still be left with 'jaggies' sometimes. The TIsophote filter seeks them out and smooths them out. It's fairly customizable and can be slow at times. For certain things its too harsh and I've heard that using a filter called Sangom can offer softer de-jaggifying... you'll have to dig to find it, but it seems to be quite popular.

By the way, Tritical's EDIUpsizer and FastEDIUpsizer on the same page are very nice edge-directed-interpolation upsizers. If you need to blow some things up, these are the best I've found. Sloooooooow...... but worth it :)
