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: Framerate conversion PAL->NTSC-DVD back to PAL/mkv

Heh, it's been so long since we've had a release, I forgot that this wasn't added till after 1.0.x was released. So as you observed, it's only in the nightly builds.

Re: Framerate conversion PAL->NTSC-DVD back to PAL/mkv

What output framerate are you using in HandBrake? HandBrake has a smart decimator that may help if you set a constant output framerate. When converting to CFR, HandBrake will preferentially drop duplicate frames when it decides that it must drop a frame in order to match the requested framerate. So ...

Re: Ripping BR/DVD as HEVC 10/12-bit?

Keep in mind that what is being stored in 10/12 bits is not the original spatial domain pixel values, but rather the temporal domain coefficients. When converting from spatial to temporal, there are rounding errors where information is lost. Also, coefficients are deliberately quantized (more inform...

Re: Parallel filtering of multiple frames

I guess most (if not all) image filters are single threaded Several HandBrake filters are in fact multi-threaded. nlmeans, lapsharp, unsharp, grayscale, decomb, combdetect are all multi-threaded. Detelecine, hqdn3d, deblock, cropscale, rotate, deinterlace, pad are single threaded. Some of the singl...

Re: Switching Field Order with Decomb Bob

My understanding is that the detelecine filter should "do the right thing" when no pulldown is present? In theory, yes. In practice, no. The detelcine filter looks for a specific cadence of interlaced vs. non-interlaced frames. It can be fooled by video sequences that spoof this cadence. And for so...

Thanks for posting your activity log. The udfread error is just HandBrake checking if the file is a BD image.

How are you determining duration? According to the log, your original is *not* 5:00.08. It is 5:00.28. Also according to the log, 9000 frames were output. At 29.97fps framerate, the duration is 5:00.30. The difference between 5.00.28 and 5.00.30 is less than 1 frame duration which is exactly what I ...

Re: How to open multiple video files at the same time on Linux?

It works pretty much the same way on linux. You open a folder, HandBrake scans all the files within that folder. Then you can add a batch of titles (aka files) to the queue with the Queue menu option "Add Multiple"

I'm guessing that this might not be possible if the output format were the same style of .iso as is used for DVDs, because as I understand it, in that case the only video encoding expected or allowed is MPEG2. But the new style .iso file format used for Blu-Ray allows for the content to be MPEG4/AA...

Re: Encoding freezes at 7.99% every time.

Do you have the same issue if you pass through the audio? The audio error didn't cause it to terminate. The reader finished "normally". I.e. the reader thinks it got an EOF. My guess is the audio error is a symptom of a corrupted file that is also causing the demuxer to just give up at the same poi...

Re: Strange performance on high core count machine

The detelecine filter is single threaded. So that filter would be my guess for the source of this behaviour. Try disabling it. The denoise filter queues up a collection of frames, then launches a parallel filter on all the frames. So if there is something that is even a little bit slower than denois...
