Shouldnt i deinterlace? (encoding with handbrake)

[squadjot]

Hi, just converted a bunch of DVDs to my media libriary..

I used Handbrake "Normal" profile.. but i noticed some interlacing.

I'm watching my movies on my TV, and, at a glance, it looks fine...

So a couple of newbie question.. needs of advice:
Should i deinterlace when i encoding?..are DVD's always interlaced?


Thanks

Here's what one of the genius's on this forum gave me not so awful long ago.

"Here is a quick Handbreak Guide for DV to h.264 in an MKV wrapper playable on the WDTV.

1. Under 'Source' button, select your DV file.
2. Under 'Container', select 'MKV'
3a. For 24p film telecine source, select 'Video Filter', 'Detelecine', 'Default'
3b. For all other formats including camcorder DV, select 'Video Filter', 'Decomb'*, 'Default'
4. Select 'start'

This will encode more quickly on your P4 2.8GHz than a full deinterlace and look very good for typical TV playback.

Alternative 1: For highest quality, encode interlace MPeg2 at >8000 KHz ave bit rate.
Alternative 2: For faster encoding, but larger file, encode xvid.


* decomb description from Handbreak Guide.
HandBrake now offers a new filter, called Decomb, that can be used instead of Deinterlace. It uses yadif in "Slower" mode, but only selectively.

Deinterlacing is a blunt weapon, and it should only be applied when it's absolutely necessary. It can also be tedious to discover whether or not a source is interlaced. And even when it is, interlacing is only visually apparent through combing artifacts. Those tell-tale horizontal lines only appear when things are in motion. But regular deinterlacing is applied to every frame without fail. This slows it down.

Decomb only deinterlaces frames that are visibly interlaced. This saves time, and makes it safe, usually, to leave it on all the time. It won't destroy the detail in progressive sources the way Deinterlace will, and should be faster than "Slow" or "Slower"."




It has worked beautifully and every time.

And of course I just realized you wanted to know about DVD, not DV. I've no idea if they're the same, but the deinterlace/decomb info should still be useful.

I thank you very much for your detailed reply!
