    I've ripped in all my Family Guy DVDs with AnyDVD to ISO, and am now mounting them in Win 8 to convert with Handbrake.

    I'm using the "Normal" preset, with:
    Detelecine - Default
    Decomb - Bob
    CRF - 22
    x264 Preset - Slow
    x264 Tune - Animation

    The output MP4s are around 250-500mb, and the quality's fine. The main problem is the buzz or jutter around the outlines of objects, even when the scene is still. Kind of like the second futurama shot on this page:
    https://trac.handbrake.fr/wiki/Decomb

    Having decomb on also seems to have fixed most of the ghosted image between frames but sometimes it seems to have just ignored certain groups of frames, and then it goes back to looking crappy.

    I also thought 500mb for 20mins of family guy was a bit big, so I downloaded a torrent (season 1 episode 1), which was about 170mb, and while the resolution was very slightly lower, the quality was perfect - all the outlines of objects were defined and all the motion was smooth.

    Would it make a difference if they converted from a region 1 NTSC DVD, or does that not have any effect? If not, what am I doing wrong?

    Many thanks.

  2. A PAL DVD will probably have NTSC/PAL field blending from the frame rate conversion. It will take more sophisticated handling than Handbrake can deliver (you'll need AviSynth). Use a program like Mpg2Cut2 or DgIndex to extract a 30 second clip from the middle of an episode and post it here.

  3. I had the same experience. To get a better picture quality, use Avisynth and QTGMC filter, but it will increase encode time.

    From season 1, track 3 (episode 3), here is an image straight from DVD without filtering:

    Here is an image after decomb using Handbrake:

    Sorry for the late response. The website kept saying "access to ...\newreply.php is prohibited" or something like that.
    I've been converting some of the later seasons, and the file size has dropped to between 100-200mb, and the quality's picked up.
    So not to sound lazy, but I'm not overly fussed about the quality if it is just the first two seasons, especially with exams coming up

    (Just out of interest) Going back to my mention earlier of that torrent I downloaded which seemed very crisp, could I expect to achieve this with AVISynth, or is this most likely because he's converted from NTSC source? Obviously there's the interlaced problem, but there's also this:

    which I described as "buzz", but wasn't sure if that was the right word. Is there any way to get rid of this from the video, or would I need a better source (TV Rip? iTunes?).

    Edit: Here's a shot from the torrent file. http://prntscr.com/300hhr

  5. You have the usual field blended NTSC->PAL conversion. It requires special techniques to restore the original 24 fps film frames. It still won't be as clean as the original NTSC release though.


    Code:
    Mpeg2Source("VTS_02_1.demuxed.d2v", CPU=6, Info=3) 
    QTGMC(preset="medium")
    SRestore()
    Crop(8,0,-8,-0)
    Some additional noise filtering would help too.

    Changed my mind... Going to have to try out AVISynth - compared to my handbrake encode, that looked perfect, thank you!

    Well, it's far from perfect. Look at the windowsill flickering 13 to 16 seconds into the clip. There is still a little ghosting here and there. Those problems probably wouldn't be there if you were starting with the NTSC source.

    QTGMC() and SRestore() are two of the hardest AviSynth filters to get set up.
