Deinterlacing for DVD – What’s the best method?

[David Bogie]

Use deinterlace filter in FCP.
Use deinterlace settings on the encoder while building your MPEG2.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

Revisionfx’s deinterlacer is supposed to be VERY good. I use it all the time, and it’s extremely slow, but looks good. Magic Bullets deinterlacer is also supposed to be nice.

Gotta disagree with Bogie. Don’t use FCP’s de-interlacer, it sucks. Use one of the ones mentioned or use Compressor 2.
Not the de-interlacer (which also sucks), but the ouput settings of Advanced Format Conversion.

Ah, very good suggestions. Neither time nor money are factors?

However, the “best” in the question does not necessarily mean the OP is looking for the best image, could be best workflow?

I suppose the more interesting questions would have been, “What is being deinterlaced, why is it being deinterlaced and what algorithm would is preferred? Blending or deleting of the errant fields.

Is this 3:2 film-based footage?

40:27 (720 x 486). Pulled from digibeta.

I’m looking for best image quality without deleted fields.

Go into Compressor and in the Settings (Presets) select the Apple/Advanced Format Conversions/8-bit Uncompressed(either PAL OR NTSC).
Select the Duplicate Selected Setting (one of the 3 buttons at the top left-it’s the right one). You can now edit the setting. Double click the setting
to open the Inspector. Right under Description at the top of Inspector are 6 buttons, select Frame Controls. Select Custom as the Frame Controls
(default is Off). Select Best for Resize Filter, Progressive as Output Fields, and Best as Deinterlace. Also select Best as Rate Conversion at bottom (not sure if that’s necessary, but what the hell). One of those 6 buttons at the top of the Inspector is Filters, and one option there is De-interlace,
DON’T use that one, it’s crap, and you’ve already selected all the de-interlacing you need.
HTH,
Ed

Thanks for the replies guys, I’ll run some tests and let ya know what I decide!

No, I mean is there any 3:2 telecine. This has to do with the framerate. If you don’t know what that means, can you tell if it was originally shot on film or videotape?

If you have the money, a Teranex conversion box will do a very good job. Resolution-wise, it noticeably gives a little extra resolution and no motion artifacts. The Teranex website has information on their motion-compensating de-interlacing:

I believe Compressor does something similar, since it supposedly inherit’s Shake optical flow processing (which is what the Teranex does). However, I’m not sure how good the actual implementation is- I’ve never compared Compressor to a Teranex. Supposedly, Compressor does get artifacts sometimes.
