With upcoming changes to data protection and privacy laws in Europe coming into effect soon, we thought this would be a good time to remind everyone that we do have a privacy policy.
This applies to all users and visitors world-wide.

We have made a few changes to the language to make it clearer in relation to this new regulation but fundamentally, the terms and your rights are unchanged.

If you have any questions about this, please feel free to ask in the General Forum

Re: Automatic croping broken in the latest nightly

I've committed a workaround for what I think is the problem here
https://github.com/HandBrake/HandBrake/ ... 71d354091d

It should be available in the next nightly build for testing.

Re: Automatic croping broken in the latest nightly

"Heavily pixelated" sounds like you're hitting BD+ encryption. What are you using to remove the encryption on the disk? No, I don't think so. Between the working and non-working versions, we switched from libav to ffmpeg. One of the patches I contributed to libav to fix such problems was modified b...

Re: Automatic croping broken in the latest nightly

Increasing the number of preview frames usually only works in the case auto cropping is too aggressive. All it takes is one frame with non-black(ish) data at the edges to cause it to back off. Actually, we create a list of each crop value (i.e. top, bottom left, and right lists). Then we sort each ...

Re: Trying to understand RF and bitrate

PSNR and SSIM metrics can be generated in the activity log during encoding if you want to see them (see the PSNR and SSIM tune options on the video tab). But they are primarily used to tune algorithms during development and should not be used for encodes you plan to keep because as mduell said, tuni...

Re: Trying to understand RF and bitrate

You can't compare settings across presets. The only thing you can say after changing a preset is that if all the other settings are the same, the results will be approximately the same with slower presets generally providing better quality and/or smaller file size, but sometimes better quality and l...

Re: Audio sync issues.

That encode log looks completely normal and shouldn't result in loss of A/V sync. If you are seeing sync issues from that encode, either your player has a problem or HandBrake does. DVDs with 23.976 fps content are inherently variable framerate. The DVD spec only permits 29.97 fps. To achieve 23.976...

Have you tried playing the same file with multiple players (that don't rely on the same possibly broken demux library)? Often these kinds of problems are problems with the player and the only solutions are to use a different player or fiddle with the encoding until you find something your player lik...

Re: Handling Mixed Telecine for Consistent Framerate

If you want a constant framerate without dropped frames, you would have to set the framerate to 119.88 which is divisible by both 29.97 (factor of 4) and 23.976 (factor of 5). HandBrake doesn't have this specific framerate, but it does have 120 which is very close. Even though the framerate is much ...

Re: Setting SRT language

"Deutsch"

It's sorted by *English* spelling, but displayed as *native* spelling. So you'll find Deutsch in the G's. It's really terrible, but I'm not sure how else to sort the list. Since native spellings are in various character sets, it's not really possible to sort by native name.

Re: How to integrate new version of x264 encoder?

On linux platforms (with the exception of flatpak builds) HandBrake gets libx264 from your system libs (i.e. we do not build it). If Mint 19 doesn't have the version of libx264 that you want in it's repository, you'll have to figure out how to build and install it yourself.

If you would like to try the next nightly build, I just pushed a workaround for the "unknown aspect" (https://git.io/vh0Vt). You may still end up with a video encoded to the incorrect aspect. The workaround also logs the unknown value, so it would be helpful if you could run the next nightly and pos...

Re: X265 2.8 seems much slower

The problem has been located. x265 versions > 2.6 now require nasm for assembly optimizations. The nightly build config didn't list nasm as a dependency, so it was getting built without nasm. Problem should be fixed in the next nightly build (which may be a day or 2 away for other unrelated reasons).

I guess if you have tons of CPUs and are serving up billions of Taylor Swift videos it might make sense to save 30%. When VP9 was initially pushed out the door, it was also extremely slow (but still faster than current AV1 by about 12x). It took a bit over 2 years for them to bring VP9 encode speed...

Re: Enable Intel QSV in version 1.1.0

Ubuntu binary releases are not built with QSV support. In theory, HandBrake on *nix can be built with QSV support enabled. But I have never done this myself.

Given the number of support requests/issues we get for the windows builds with QSV, I'm not in any hurry to enable QSV in Ubuntu builds.
