Different decomb/deinterlace options?
Hi,
I recently converted an interlaced DVD using the High Profile preset. Using the default Decomb option, the resulting file was deinterlaceds, yes, but it was very choppy, skipping ahead each second or so. I saw there are other deinterlace/decomb options available. Can anyone explain to me the differences and does someone have better experiences using another option than the default one? Thanks.

Re: Different demob/deinterlace options?
did you try to detelecine it instead? if it's telecined, that will give better results (usually) than decomb/deinterlace... detelecine and decomb can be used together
bob outputs one frame per field, so it doubles the framerate... nice for fully interlaced and high motion content...
the other deinterlacing methods aren't going to be of much help to you if decomb has the issue... as decomb uses blend or slower selectively(i think?) or bob if you select that option...

Re: Different decomb/deinterlace options?
Nope, didn't try that, but I'll give it a go. Is there a similar auto detection option for the detelecine filter as decomb is for the deinterlace filter? Or can I leave detelecine on all the time and it can itself figure out if the content is telecined or not?

Re: Different decomb/deinterlace options?
i think i remember someone saying that's it's usually safe to enable all the time for interlaced source could be remembering wrong though... either way, if it can't find any fields for frame reconstruction(or whatever the technical term for it is), it shouldn't do anything(?)
Re: Different decomb/deinterlace options?
I wouldn't enable detelecine for PAL sources myself, but YMMV.

Re: Different decomb/deinterlace options?
i keep forgetting about PAL everything i deal with is NTSC (JP with a sprinkle of US)... but yeah, PAL / 25fps telecined to 29.97fps can be problematic
Re: Different decomb/deinterlace options?
Thanks. Actually the source dvd is PAL. But I'll try to encode it without any filters on and try the deinterlacer in Plex Home Theater since that's what I view my files on. Any comments/experience on the deinterlacer in PHT? Thanks all

Re: Different decomb/deinterlace options?
what deinterlace modes does PHT have?
... and did you try bob?

You'll need to force interlaced encoding in HB to give that any chance at working.jnyberg wrote:Thanks. Actually the source dvd is PAL.

Re: Different decomb/deinterlace options?
How do I force interlace when encoding?

Re: Different decomb/deinterlace options?
put in the extra options box (or tff=1 or bff=1 depending source... PAL is usually bff i think?)
and i think you need crop to be 0,0,0,0 with strict anamorphic(?)
not sure how any of PHT deinterlace methods will fare against handbrake's though...
Code: Select all
interlace=1

Re: Different decomb/deinterlace options?
Strict anamorphic is a must, since we don't do interlaced scaling. I don't think crop will be an issue. There is no PAL == bff rule, it depends on the source… DV is usually bottom field first, DVD usually top field first. Not sure about the rest. Rule #1: know your sourcemoneymatt4life wrote:putin the extra options box (or tff=1 or bff=1 depending source... PAL is usually bff i think?)Code: Select all
