Re: 7.1 audio for Apple TV 4K possible?

Unfortunately, only the E-AC-3 solution is workable as multichannel AAC over HDMI is basically not a thing.

Re: Display size of output video

The source is letterboxed and HandBrake is automatically cropping 140 pixels of black off the top and 140 pixels of black off the bottom. You're already getting the maximum resolution.

Please follow the "Flatpak bundles" section here exactly: https://handbrake.fr/docs/en/1.3.0/get- ... stem-linux

If that does not work for you, then there's something weird going on and we'll have to gather more info about your system.

Re: Optimal Encode Settings Blu Ray -> Plex

Remember, the bit rate restrictions imposed by level are per second (per buffer period but that's another discussion). One can have instantaneous (sub-second) bit rate much higher, e.g. a large complex keyframe followed by much smaller frames, so that the total bit rate sum for the period is less th...

Re: Constant Rate Factor vs. Constant Framerate and other video controls

The section of the documentation you're referring to is focused on the most common encoding workflow, and most of those controls shouldn't be changed. We plan to add more advanced fine tuning information in another section down the road. I'm sure someone will be happy to explain the frame rate and q...

Re: Problem with video encoding on AMD 3400G

Unfortunately, this is common for transport streams, especially broadcast recordings. Some people have had good luck using VideoReDo's quick stream fix before encoding with HandBrake.

Glad you found something you like.

One thing to note, while slower encoder presets result in smaller file sizes with x264 (which seems sane), the opposite is true with x265 (ummm). ;)

That's because we kept them around for compatibility. They're quite old and deprecated so I recommend the newer syntax.

Re: Fix stutter caused by source/capture different FPS?

60 being more than 50 doesn't preserve the original frames, sadly. The timing is permanently off and stutter baked in. Ideally you would recapture the source properly.

Re: H265 in new HandBrake 1.3.0 gives 30-60% higher bitrate

Seems to be more than just changes between encoder versions. They aren't using exactly the same settings (typical). Note the presence of strong-intra-smoothing, which we disable in the official presets.

You're welcome to do some analysis on those options. :)

I will say, if you're feeling the need to disable SAO, you probably need tune Grain anyway.

Re: Optimal cores for Apple 2160p60 4K HEVC Surround preset?

Remember, mduell's 16 thread result wasn't much faster than the 8 thread result because the CPU only has 8 physical cores. The minor speed boost is due to hyperthreading. 16 physical cores would likely be much faster.

Re: Understanding denoising (NLMeans) paramters

As far as preserving more detail, you're probably at or close to the algorithm's limit. You could try changing the patch size and search radius to 5 and 5 instead of 7 and 3; it might be better and it might be worse for your source. Encoding time should be about the same, maybe slightly faster.

Re: Encode start time search

If I'm not mistaken, the previews locations are calculated at a byte offset, not a time offset. Precise time start requires scanning the source, as skipping to a byte offset is no guarantee of time.
