This will add 222 pixels black border on top and 224 pixels at bottom. For your video, you can add the following text to the AviSynth script: The filter in AviSynth you need is called "AddBorders".
#Xmedia recode 4k to 1080p how to#
It does require some basic understanding of how to edit such a script. I don't know of any GUI tool that can help adding the borders, but AviSynth can do this.
Black borders have to be added first to get compliant 3840x2160 resolution. I think the trouble lies with the video resolution. So, is there something with these encoding settings below that would cause the encoder to go trigger uhd-bd=0?Įncoding settings : cpuid=1111039 / frame-threads=1 / wpp / no-pmode / no-pme / no-psnr / no-ssim / log-level=2 / input-csp=1 / input-res=3840x1714 / interlace=0 / total-frames=0 / level-idc=51 / high-tier=1 / uhd-bd=0 / ref=5 / no-allow-non-conformance / repeat-headers / annexb / aud / hrd / info / hash=0 / no-temporal-layers / no-open-gop / min-keyint=1 / keyint=24 / gop-lookahead=0 / bframes=3 / b-adapt=2 / b-pyramid / bframe-bias=0 / rc-lookahead=24 / lookahead-slices=0 / scenecut=40 / hist-scenecut=0 / radl=0 / no-splice / no-intra-refresh / ctu=64 / min-cu-size=8 / no-rect / no-amp / max-tu-size=32 / tu-inter-depth=4 / tu-intra-depth=4 / limit-tu=0 / rdoq-level=2 / dynamic-rd=0.00 / no-ssim-rd / no-signhide / no-tskip / nr-intra=0 / nr-inter=0 / no-constrained-intra / no-strong-intra-smoothing / max-merge=1 / limit-refs=0 / no-limit-modes / me=1 / subme=2 / merange=57 / temporal-mvp / no-frame-dup / no-hme / weightp / weightb / no-analyze-src-pics / no-deblock / no-sao / no-sao-non-deblock / rd=2 / selective-sao=0 / no-early-skip / no-rskip / no-fast-intra / no-tskip-fast / no-cu-lossless / no-b-intra / no-splitrd-skip / rdpenalty=0 / psy-rd=0.00 / psy-rdoq=0.00 / no-rd-refine / no-lossless / cbqpoffs=0 / crqpoffs=0 / rc=crf / crf=0.0 / qcomp=0.60 / qpstep=4 / stats-write=0 / stats-read=0 / vbv-maxrate=98000 / vbv-bufsize=99000 / vbv-init=0.9 / min-vbv-fullness=50.0 / max-vbv-fullness=80.0 / crf-max=0.0 / crf-min=0.0 / ipratio=1.40 / pbratio=1.00 / aq-mode=3 / aq-strength=0.00 / cutree / zone-count=0 / no-strict-cbr / qg-size=32 / no-rc-grain / qpmax=69 / qpmin=0 / no-const-vbv / sar=1 / overscan=0 / videoformat=2 / range=0 / colorprim=1 / transfer=1 / colormatrix=1 / chromaloc=1 / chromaloc-top=0 / chromaloc-bottom=0 / display-window=0 / cll=0,0 / min-luma=0 / max-luma=1023 / log2-max-poc-lsb=8 / vui-timing-info / vui-hrd-info / slices=1 / no-opt-qp-pps / no-opt-ref-list-length-pps / no-multi-pass-opt-rps / scenecut-bias=0.00 / hist-threshold=0.03 / no-opt-cu-delta-qp / no-aq-motion / no-hdr10 / no-hdr10-opt / no-dhdr10-opt / no-idr-recovery-sei / analysis-reuse-level=5 / analysis-save-reuse-level=0 / analysis-load-reuse-level=0 / scale-factor=0 / refine-intra=0 / refine-inter=3 / refine-mv=3 / refine-ctu-distortion=0 / no-limit-sao / ctu-info=0 / no-lowpass-dct / refine-analysis-type=0 / copy-pic=1 / max-ausize-factor=1.0 / no-dynamic-refine / no-single-sei / no-hevc-aq / no-svt / no-field / qp-adaptation-range=1.00 / scenecut-aware-qp=0conformance-window-offsets / right=0 / bottom=0 / decoder-max-rate=0 / no-vbv-live-multi-pass I quickly ran an encode using Handbrake with no settings applied other than uhd-bd=1, and it was able to maintain this without going to uhd-bd=0. If the encoder is unable to do so, this option will be turned OFF. If specified with incompatible encoding options, the encoder will attempt to modify/set the right encode specifications. Is there a way to check for uhd-bd=1 compliance before I encode something? I'm using Xmedia Recode right now, and I'm using the option for Ultra HD Blu-ray.
