Yes, I did take into account to make sure no black borders.

hello jdobbs

when estimates will be available the next version of bdrebuilder, to make the backup fullbd HVEC?
thanks

I meant movie-only backup to MKV in that post. While full HEVC backups may be coming, since they can't be played by most players, I'm not sure when I might do that. If I did, it would likely be for archival purposes rather than playback.

[Edit] Hmmm... MPC-HC seems to recognize a movie-only BD that has HEVC and AAC in it. I'll do some testing on full backups, although it appears it only support playlist playback rather than menus, etc. Does anyone know exactly what its capabilities are? I'd really be interested in seeing how a full backup in HEVC might look on a single layer DVD.

powerdvd 14 and tolalmedia6 playback perfectly h265, would be perfect, able to choose between a fullbluray encode in h264(avc) or h265(hvec) in the menu setup default option of bdrebuilder.

Do you know of any guidelines as to what the limitations are that should be used? I'm wondering about b-frame limitations, GOP sizes, etc... I guess a start would be to use the same rules as AVC.

no, surely you and your experience, you get to do very well, or at least you can try.

Jdobbs, I will do some test run and see what I can find out.

What'll you use for testing? PowerDVD 14?

Yes, indeed. Unless you want something else.

I am gone use different preset in x265 and see what setting get use during encode with help of media info and also observe what works and what doesn't.

I already have mkv where average bitrate of video is around 10Mbits and aac audio with preset slow in x265.

Tip: By default x265 uses open gop with 4 b frames up to preset slow. After that in preset slower to placebo it uses 8 b frames.

I've read that the BD standard is going to use Rec. 2020 for 4K which means 10 bit color depth. That may be a consideration too.

Powerdvd playback



Setting used with preset slow

Encoding settings : wpp / ctu=64 / tu-intra-depth=1 / tu-inter-depth=1 / me=3 / subme=3 / merange=57 / rect / no-amp / max-merge=3 / no-early-skip / no-fast-cbf / rdpenalty=0 / no-tskip / no-tskip-fast / strong-intra-smoothing / no-lossless / no-cu-lossless / no-constrained-intra / no-fast-intra / open-gop / interlace=0 / keyint=240 / min-keyint=23 / scenecut=40 / rc-lookahead=25 / bframes=4 / bframe-bias=0 / b-adapt=2 / ref=3 / weightp / no-weightb / aq-mode=2 / aq-strength=1.00 / cbqpoffs=0 / crqpoffs=0 / rd=4 / psy-rd=0.00 / psy-rdoq=0.00 / signhide / lft / sao / sao-lcu-bounds=0 / sao-lcu-opt=1 / b-pyramid / cutree / rc=crf / crf=20.0 / qcomp=0.60 / qpmin=0 / qpmax=51 / qpstep=4 / ipratio=1.40 / pbratio=1.30

Please note setting are from crf mode, however two pass works as well with same setting and seeking back and forth work as well along with chapters and subtitle.

Next task AVCHD and see how it goes.

X265 Preset

This table shows what setting get applied with different preset. Certain setting such as GOP is always set to open by default.

Jdobbs, Powerdvd does not play if output is blu-ray format with hevc encoded footage. However playing individual m2ts work fine, highest preset which works well is preset slow anything else result in problem with decoder, example b frame increase by 4 more with preset slower in comparison to preset slow.

DTS-HD and subtitle decoding works fine.

Just for reference preset slower take 3X longer over preset slow.

On my system I am getting 0.70fps on preset slower.

So you're really not getting anything you wouldn't get with a combination of MKV and MPC-HC. That's disappointing. I was hoping for full playback capabilities.

Thanks for testing it.

I am disappoint as well, but I guess it is gone be this way so be it.
Anyways right know I see full SBS option which can be done with hevc, can you add (if not to much hassle) half SBS and possibly m2ts muxing with DTS_HD etc.

You can do that just by creating a new preset in ALTERNATE.TXT using the existing options.

Here's an example:

[00036]
caption=MKV Container, HEVC Half-SBS 3D, Intact Audio
vEncoder=1
vBitrate=2000
aType=2
vFormat=5
cType=1


It assumes you have "Enable SBS output movie-only..." set in SETUP. It will take the 3840x1080 input from a 3D source, convert it to 1920x1080 (half SBS) and will keep the audio intact. I'll add it as a default in the next release.
