![]() ![]() The "add AAC 2 channel 256kbps audio as first track" idea is mainly for pandering to Apple devices that don't support AC3 or multichannel audio. It's a big topic and ideally you'd not using any filtering for a fully progressive source, but unless you want to spend a fair bit of time on encoding, the easiest solution is to leave the decomb filter enabled and let Handbrake output a variable frame rate if need be, and if you do want to spend a lot of time on it then you probably wouldn't use Handbrake as it's designed to be fairly automatic.Īre you sure the decomb filter caused the moire/shimmering? It wouldn't be unusual for it to be present in the source video. ![]() I've seen quite a few Handbrake encodes where someone forced a constant 29.970fps for a "hybrid" NTSC DVD, so the interlaced sections were correctly de-interlaced to 29.970fps, but as the decomb filter converts the film sections to 23.976fps, every fourth frame has to be duplicated to output a constant 29.97fps and that's hard to watch. Handbrake's Decomb filter is designed to automatically deal with that, and I think by default it outputs a variable frame rate, so in theory the film sections with pulldown are detelecined for 23.967fps progressive, the progressive parts are left progressive, the video sections are de-interlaced to 29.97fps, and the output frame rate changes accordingly. For NTSC, film can be encoded as progressive, it can be encoded using 3:2 pulldown (which looks similar to interlaced video if it's decoded as progressive), or it can contain interlaced video, and sometimes it's a combination of all three. The problem is, DVDs can be an encoding minefield because there's many possibilities. I don't use Handbrake much myself, however. I've included a screenshot of the audio settings to get a better idea of what I'm asking. I'm also wondering about "mixdown" settings - is that for receivers that can't decode full surround tracks? Would a setting of "Dolby Pro Logic II" allow the audio to be played on my Apple TV through my TV speakers? I'm guessing it still will because even though Pro Logic is not a native Apple TV audio format, the codec is AAC which should still allow the audio to play on my TV via my Apple TV. ![]() For audio: in addition to adding the AAC 2-channel track as the first track for compatibility, what settings do I need to adjust to ensure that the original Dolby Surround track(s) will play on my receiver? I'm assuming I'll need to include the tracks with the "AC-3 Passthru" option because Apple TV can't natively decode 5.1 like a receiver can. ![]() Does this sound like an appropriate setting for DVDs? Should I set the framerate to "same as source" to accommodate my PAL DVDs? With the above in mind, I'm planning on using the "HQ480p30Surround" preset for my DVDs with all the video presets untouched (except, possibly, for the deinterlacing presets). If the file already contains an h.264 video then the file is remuxed but if the video is not already h.264 then the file is transcoded using Handbrake with a HIGH PROFILE and web optimize. Setup MP4 for "fast start" or "web optimized" whichever you wish to call it. On the Plex forums I found a post with these settings/workflow, and they seem sensible to me:Īdd AAC 2 channel 256kbps audio as first track (for compatibility with all devices) if needed In addition to solving the moire problem, I would just like to know the best video settings for ripping DVDs with Handbrake. Should I turn deinterlace off then? Or are there certain situations where I'd want to keep it on? How would I diagnose which DVDs need some kind of de-interlacing? I do have some DVD-Rs of old VHS, and I know VHS is interlaced, so should I apply deinterlacing for those? However, my rip was done with the "decomb" option on, and it caused that moire/shimmer. I've read that leaving it on "decomb" may be best to account for some DVDs that are interlaced (most are progressive, if I understand correctly). After futzing around in various forums, it seems either leaving de-interlacing off entirely or setting it to the "decomb" option may be the the way to go. My first rip went quite well, but I noticed moire on the pattern of a character's suit (see screenshot - it doesn't show in a still shot, but just to give you an idea of the shimmer I'm seeing). I've started ripping my library of DVDs using Handbrake so I can upload them to Plex for streaming on my iPad and Apple TV (4th Gen). ![]()
