Re: Ubuntu 16.04.3: Handbrake not 100% of all CPU cores (using stebbins ppa)

100% CPU load is one thing, but is it actually faster? Look at the final 'average fps' and see if HandBrake on Windows is truly faster than Linux.

It could be that the two OS measures load differently.

I'm unable to uncompress the rar file. For dark scenes, see if using aq mode 3 helps.

Re: Ripping Blu Ray collection to the same specs as iTunes store HD movies

nhyone - Thank you, as you're the only one that actually said anything helpful. Thanks. :D Some people think they can do better by tuning average bitrate by the movie, but that's what CRF does: constant quality by varying the bitrate.

Re: Ripping Blu Ray collection to the same specs as iTunes store HD movies

I always give the same suggestion: always use CRF. To choose the CRF to use, pick a video, encode it at 18, 20, 22, 24. Pick the highest number that looks okay to you. Then go one level finer. Say you pick 22, then you should try 21 and 23. Think choose again. You can use this number for 99% of your...

Re: Any advantage to HEVC for Blu-ray?

We're talking single digit percentages associated with block size? 1%? Less? The CTU wiki page cites a difference of 18% comparing CTU 16 to 64 in one study of 1080p videos. H.264 allows MacroBlocks of 16x16 only. I've always wondered what if someone defines a "level 6" and extend it to 64x64? Will...

Re: Any advantage to HEVC for Blu-ray?

Said block sizes obviously aren't HEVC's only edge over older codecs, but the idea that HEVC's efficiency advantage is more significant at higher resolutions is at least partially true. x265 is too aggressive in using big block sizes and it is common to see people limit CTU to 32 for 1080p videos. ...

Re: Help with Optimal H.265 1080p settings

It's a bad idea for high quality encodes, which is why we set strong-intra-smoothing=0 in the official presets that use x265. Are you setting other parameters too? The x265 parameters are tuned for clean lossless 4K source. They are different from the source we consumers normally use -- H.264 1080p...

It'll be nice if the command-line HB can emit the GUI JSON file. It can already do so, but only as part of the log.

The CLI emits the values as strings, unlike the GUI that emits them as numbers...

Re: Is it true that there is no big gain of using more than 5 reference frames?

Handbrake can always check the advanced settings and cap the limit. :D

From what I googled, only ref is limited by levels, bframes is not. And for the typical level 4.1, the two most common ref limits is 9 for 720p and 4 for 1080p.

Re: Help with Optimal H.265 1080p settings

One thing I've learned is that (using 12-bit H.265) with a grainy source, when I go 2-pass/bitrate, I need to leave Encoder Tune set to None to retain that noisy detail. I tuned Grain and it looked worse. But when going constant quality (trying 30 and 32) if I leave the Encoder Tune at None it is b...

Re: Quality beyond Very Slow or Placebo in H.264?

I also think this discussion is interesting when reviewing the Official Presets Pane. The preset for "Super HQ 1080p30 Surround" uses the "veryslow" Encoder Preset and CQ RF of 18. Isn't this overkill for no discernible improvement (aside from bragging rights as someone offered above)? The "HQ 1080...

It is my belief that x264 tends to "over-compress" dark film, as it thinks the details are too dark and can't be seen anyway.

If you just want to add subtitle to a mkv file, you should be using MKVToolNix. Don't transcode the video unnecessarily.

Re: Quality beyond Very Slow or Placebo in H.264?

You have to be aware that the presets is not a linear scale. There are three variables: time, size and quality. Presets affect mainly time and size, not quality. (This is not strictly true, but is mostly true.) Bitrate and CRF have a much bigger impact on quality. Edit: note that this applies to x26...

Re: Efficient use of high core counts in next gen chips

For slower presets (slower, veryslow, placebo), x264 is limited by the encoder. You can use 10+ cores, no problem. (But they won't be at 100% for other reasons.) For faster presets, x264 is bottlenecked by its lookahead. It can't analyze the video fast enough to feed the encoder. There are two more ...

Re: Does this exist ?

Which presets do you have in mind? Here's an easier way: pick a preset and just vary the CRF (say 18, 20, 22, 24), find the two numbers where the video switches from transparent to not-so-transparent and do it one more time (say 18, 19, 20). Then pick the highest number that is transparent to you. O...
