View Full Version : Handbrake - dealing with interlaced image...

Jan 27, 2011, 06:00 PM
Hi all,

I am trying to rip my Flight of the Conchords boxset, however on the standard ATV2 preset I am getting a pretty bad interlaced picture.

I have searched a bit through the forums, and it seems as though it is recommended to turn on the "Decomb" filter.

I have gone into picture settings and put the decomb on to Default. I did a live preview but I am still getting an image like the following...


Any ideas? Its a PAL DVD.

Try setting the filter to "deinterlace" ...

the deinterlace filter and or maybe try the apple TV (original)

deinterlace at slowest setting.

Decomb sort of removes the wiggles caused by "soft" interlacing. If you aren't sure if the video is interlaced, supposedly decomb is the best choice. If you see strong "hard" interlacing such as your example above, use the de-interlace option set to slowest.

For my 1st gen AppleTV, I use the AppleTV preset and select the Decomb filter (set to Default). That always seems to take care of interlace issues.

For what it's worth... I've never used the decomb filter, have always used Deinterlace Fast and it works fine. Any movie that I question if it will be interlaced, (animated, older movies, or TV Shows from the '80s) I hit the preview button to see if those lines are there.

OK, tried last night. Used the Deinterlace setting (fast i think). Its removed some of it but led to quite a jerky playback. Video was not playing smoothly.

Will try again!

Some older DVDs are just terribly mastered. If they have a mix of different material on disk (like CGI and normal film) then they are often not flagged correctly.

Usually if the material is interlaced you should use:
-Detelcine - Default
-Decomb - Default

Old stuff (like the early Star Trek TNG) that's poorly done breaks due to the Detelcine. For that I do:
-Detelcine - Off
-Deinterlace - Slower

In most cases the top set works well as it's smart and used selectively. The bottom is more of a "dumb" arrangement so it's bluntly applied to everything and can squash detail in scenes that don't need the deinterlacing.

OK, tried a few more times, I have tried a few different settings and presets.
I used High Profile with RF 19.25, and set
-Detelcine - Default
-Decomb - Default
as per the last suggestion. The picture quality is very good. Interlacing seems gone, however the video plays slightly jerky. It is not very smooth.

This keeps happening everytime I add the picture settings to combat the interlacing.
Its really bugging me! Thought it would be a straight forward rip. Would just nab it off iTunes but it seems to go for quite a premium at 19.99 for the two series! Bit of a ripper when I already have the DVDs!

Anymore suggestions?

I'm having the same issues with my Simpsons DVDs using the AppleTV2 preset. I will try the suggestions in this thread... thanks!

I used decomb for simpsons (season 1-7) and that worked fine. AppleTV1 preset.

Tried again using Decomb and ATV1 preset. Still jerky playback. Bloody things doing my head in!

I have just used the high profile and left everything else alone and that has worked on the TV shows I was having issues with.

Well i'm still out of ideas and without a solution for this one.

If I use the standard ATV2 I get a nice smooth payback, but with bad interlacing. Anytime I introduce the deblock filter, it deals with the interlacing, but playback is jerky.

Anymore ideas to try or suggestions why? I've tried pretty much every setting recommended!

You might post this on Handbrake forums:

I have, although no one seems to have offered up any suggestions!
