Re: Question - Encoding 8-bit Blu-ray using 10-bit encoder
The reasons are complicated, but you are not imagining things. Banding is indeed reduced when using a 10 bit encoder with 8 bit sources. Longer answer... In encoded video, there are no "pixels". Instead there are frequency coefficients. Frequency coefficients are a representation of the im...

Re: Mixed Prog/Telecine standards
I know of no standards that define the parameters for how interlaced and telecined content may be interleaved. I'm sure production houses have procedures they follow to some extent, but my guess is even these would be soft rules. More generally, changes between interlaced and telecined content most ...

Re: Default (and forced) subtitles in the soure not marked as default in HandBrake
Nice one, very helpful and constructive. mduell's statement is provocative, and lacks tact, but is also true. There are a number of features that would be nice to have that nobody has the time or inclination to work on. The HandBrake developers are a small team (you can count them on 3 to 5 fingers...

Re: Anamorphic
Anamorphic means that pixels are not square (they are rectangular). Setting anamorphic to none results in square pixels. Using anamorphic pixels, in this example, results in more detail being preserved in your encoded video. But in some use cases, this may not be needed or desirable. For example, if...

Re: "Video Pass thru" ?
The "hard" problem with video passthru is maintaining A/V sync in scenarios where the streams are damaged (this frequently happens with broadcast captures) or sources that have non-seamless branches (DVD and BD). To maintain sync, HandBrake needs to sometimes drop frames. This is easy with...

Re: general question: settings for merging multiple .MXF-files into one single MP4-file
ffmpeg is probably the tool you want to start with. Google turned up this tip https://www.arj.no/2019/11/03/convertin ... th-ffmpeg/
If you also want to re-compress or convert the video to another codec, then you could post-process with HandBrake.

Re: [QSV] - VBR Feature Request / QP Max Bitrate Limit
I mean, is this a mistake in the analysis or how can this happen? The compression algorithm knows nothing about the bitrate or quality of the original file. In fact, the original file is uncompressed before being passed to the encoder. The encoder sees only raw uncompressed frames. Strongly compres...

Re: [QSV] - VBR Feature Request / QP Max Bitrate Limit
As mduell pointed out, the best way to control bitrate spikes when using a quality metric for encoding is through vbv-maxrate and vbv-bufsize settings. These settings are specifically designed for this purpose. QP (like RF) will not limit bitrate. QP is a quality metric. The encoder will apply whate...

Re: How best to deinterlace a source that has both progressive and interlaced content?
Generally, if you don't have a playback device that requires constant framerate, it's best to just leave the framerate set to variable "same as source". When using bob deinterlacing, you won't have to be concerned with matching the output framerate to twice the input framerate. Additionall...

I'm somewhat surprised it can even be coaxed to build for arm. Since none of us has done this on linux, you're going to have to do the heavy lifting yourself in figuring out what's broken. Start by doing a clean build with debug symbols enabled and optimization disabled. E.g. from the top of the Han...
