Re: MKV subtitle pass-through

What are "matroska subtitles"? Matroska is a container that supports a variety of subtitle formats, but it is not a subtitle format.

Re: V1.7.1 and .2 - Audio not supported on Bravio TV

What if you do passthrough on the audio track instead of pointlessly reencoding it at a higher bitrate?

Re: How to recode a video file with a variable bitrate to a constant bitrate CBR

Best you can do with HB is pick an unreasonbly high quality setting (e.g. RF 1) then cap the bitrate with vbv-bufsize/vbv-maxrate.
CBR/constant bitrate does not appear anywhere on that page.

Why does DVDFab implement this? You set the file size and the bitrate is automatically adjusted.
Less picky users? Decoding the entire video first?

Re: Question about the H.265 encoder

rect=1 (the default) is used when the options are empty, do I understand this correctly? Yes. Is there a good overview or guide? https://x265.readthedocs.io/en/stable/cli.html My conclusion is that H.265 10-bit, without options, takes about twice as much time as H.265, but the output file is smalle...

Re: Question about the H.265 encoder

Eh, I'd keep at least rect=0; rect=1 (the default) is excessively slow for what it gains.

Re: Question about the H.265 encoder

You've specified additional options on your 10-bit encode that improve the speed of the encode at the cost of compression: [18:32:52] + encoder: H.265 (libx265) [18:32:52] + preset: veryslow [18:32:52] + profile: auto [18:32:52] + level: auto [18:32:52] + quality: 18.00 (RF) [18:30:32] + encoder: H....

Re: 98% CPU?

Post an encoding log from before with the previous behavior, and now with the new behavior, so we can see what differences may have lead to your observation.

Re: settings guide for my specific setup

The preset you're using would be a very reasonable. Not sure what you've been encoding from previously if not disk rips.

Re: transcode video with a lot of grain?

For 4K with a lot of grain, I'd use SVT-AV1 10-bit as long as it's not DV.

If you have to use x265, I'd use encoder tune grain and a higher RF. Or use a lot stronger nlmeans strength.

Either way, disable decomb/deinterlace.

Re: Roku playback skips

We'd need to see the encode log, not just the scan.

Also you've posted conflicting information about if constant frame rate has the problem or not.

Yes, H.265 with VTB will be better than H.264 with VTB at the same bitrate.

Re: Confusing Apple M1 Performance

If you want 4-5GB for a 2h movie, you need a video bitrate around 5000 kbps not 20000 kbps.

Size, speed, quality: pick two.

Re: nvenc won't work

Yea that's the issue, a lot of the OEMs don't keep the drivers up to date or submit for WHQL, so WIndows Update may not offer them.

Update your GPU driver to the latest (546.33); you're on 528.96 if I'm reading it right.

Re: How to achieve this ?

Given that your source doesn't look as good as their encode, either they started with a better source, or did some filtering that looks desirable to you (denoise, sharpening, etc).

x265 10-bit for the encoder preset veryslow and RF 18

And of course, start with a pristine clean source.

Re: Not Quite the Same

Indeed. Choosing a slower preset can help mitigate that somewhat, but not much.

Again, with the log, and maybe a description of the quality reduction, we may be able to provide additional recommendations.

RF, assuming everything you've said is accurate and complete. The encoding log would help understand if that's the case.

Errors in the source, but try the current release.
