  1. I have a lot of DVDs of "Elmo's World", which is a mix of live action footage and animated footage. However, a lot of the show has Elmo (live action) interacting with computer animated characters. I use Handbrake for all my encodes, but Avidemux is also a option. Here's where the issue lies; the live action footage can easily be de-combed with the bob de-interlacer in Handbrake, and end up at 59.94 frames per second. However, it seems that the computer animated characters were animated at 29.97 frames per second, so if I encode at 59.94 frames per second, any of the computer animated things have jagged lines, as well as duplicate frames. I know how to fix the duplicate frames (Handbrake has a setting for frame rate where, I assume, it doesn't add any duplicate frames; have yet to try it), but the jagged lines is an issue I've yet to find a fix for; I thought I read somewhere that the bob de-interlace setting is causing the jagged lines, but I'm not sure if that's true or not. My goal is for my final encode to have the live action footage at 59.94fps, to have duplicate frames removed (figured out how to do that already), and remove the jagged lines from the picture. Is that too much to ask, or can it be done? If it can't be done, I can live with the jagged edges, but I thought I'd ask before I encode them all (rather know before any encodes, rather then after, because then I'd have to re-encode them). I've added a short sample where Elmo interacts with a computer animated character (around 30 seconds long). Thanks for any help that can be given!


    EDIT: After watching it again, I noticed that the computer animated characters AREN'T interlaced; I thought they were, for some reason. I'll check if in Handbrake if there's a setting to interlace only whatever's interlaced in a frame. There's a setting to ignore fully progressive frames, but I don't think it's programmed to de-interlace part of a frame and leave the rest alone. Pretty sure I'll have to use Avidemux for there.

    It's true. Handbrake uses Yadif and that's what it does. I have no idea what deinterlacers are available for AviDemux (never used it) but if you're serious about this, then it's about time you learned how to use AviSynth. Then you'll have access to QTGMC and your aliasing will disappear when you're deinterlacing.

  3. Yes, QTGMC does pretty well with that video. Though it does seem to "invent" some additional motion and there are a few small ghost artifacts here and there. Nothing in Handbrake or AviDemux will come close. QTGMC() with default settings:

  4. I've installed AviSynth, and looking at that improved sample, I'm glad I did! That's way better then what I was able to achieve with both Handbrake and AviDemux. A few small ghost artifacts is totally preferred then jagged lines (I actually saw no artifacts in the improved source, but maybe I'm just blind to them, or they're only noticable if viewed frame by frame. Thanks for the help! I'll certainly be using AviSynth for the DVDs.

  5. They ghost artifacts are really on visible when looking at still frames. QTGMC is one of the hardest filters to get set up and it runs pretty slowly. Be sure to download and install (copy the filters into AviSynth's plugins folder) all the other filters it depends on. There's a post around here with all the filters you need in one zip file.
