The legal issue:
Licensing is a nightmare becuase MPEG-LA owns a lot of the patents in "video and audio stereams in a single file". Combined with all the other features of the container, who knows what other patents it potently violates in different countires? Do we have patent lawyers that are familiar with MKV's features? type halp than /quit

The Engineering Issue:
This format can support so many different codecs, streams, subtitle formats, multiples of all of these. How do we handle this in a way that doesn't piss off our customer when their TRANSFORMERS.8.REPACk.10BIT.H.265.mkv doesn't play back? What about future formats? What? Now we've got to pay for a DTS-HD license because its the original audio format? What if someone makes a .mkv file that contains so many streams that it crashes our TV and loads some arbritrary payload? What if I want to go home at 5:00PM today instead of implementing a container format used 95% of the time to pirate video files?

$40 LG and Samsung blu-ray players can play MKV now. They can even play 10-bit encodes. Since they're already licensing h.264, aac, ac3, and all the codecs, it's a simple matter of just adding the ability to read the container.

m4v is an apple format i think (MPEG-4 video)

m4v is just mp4. Usually it indicates that it only has a video stream in it, like m4a indicates only an audio stream, but obviously no guarantees.

They weren't DVDs (though somebody did make DVDs that would start to degrade after being exposed to open air). They were discs encoded with the DivX codec instead of MPEG-2, and used a different copy protection system IIRC.

No, DIVX discs were MPEG-2 and basically the same as DVDs. The DivX codec (a renamed MS MPEG-4 v3 codec) came later and was so named to poke fun at the failed DIVX discs.

http://www.tested.com/tech/web/453188-what-you-should-know-about-h265-video/

"H.264's successor is coming...eventually. The video codec has been approved, but won't change the face of web video with support for 4K and 50% lower bandwidth costs until chips with hardware decoding capabilities are released in 2014."

...

"Interested in a super technical description of how H.265 works compared to H.264? Read these snippets from the Overview of the HEVC Standard white paper:

"The core of the coding layer in previous standards was the macroblock, containing a 16�16 block of luma samples and...two corresponding 8�8 blocks of chroma samples; whereas the analogous structure in HEVC is the coding tree unit (CTU), which has a size selected by the encoder and can be larger than a traditional macroblock. The CTU consists of a luma CTB and the corresponding chroma CTBs and syntax elements. The size L�L of a luma CTB can be chosen as L = 16, 32, or 64 samples, with the larger sizes typically enabling better compression. HEVC then supports a partitioning of the CTBs into smaller blocks using a tree structure and quadtree-like signaling.

...new features are introduced in the HEVC standard to enhance the parallel processing capability or modify the structuring of slice data for packetization purposes. Each of them may have beneﬁts in particular application contexts...

H.265 adoption will be slow until mass hardware support is behind it, which seems to be at least 18 months away.
1) Tiles: The option to partition a picture into rectangular regions called tiles has been speciﬁed.

2) Wavefront parallel processing: When wavefront parallel processing (WPP) is enabled, a slice is divided into rows of CTUs...WPP provides a form of processing parallelism at a rather ﬁne level of granularity, i.e., within a slice. WPP may often provide better compression performance than tiles (and avoid some visual artifacts that may be induced by using tiles).

3) Dependent slice segments: A structure called a dependent slice segment allows data associated with a particular wavefront entry point or tile to be carried in a separate NAL unit, and thus potentially makes that data available to a system for fragmented packetization with lower latency than if it were all coded together in one slice."

Well you can stack palettes to have more than 256 colors but that's sort of breaking the specification and also that's not changing the palette per frame.

Why don't just distribute HD rips in mp4? That would solve so many of these issues since they are already encoded as h264, is it because mp4 doesn't support their stupid subtitles or what?

Because AC3 audio isn't supported in MP4 containers. All the SD releases of TV shows use AAC audio and mp4 containers.

Shaggar posted:

the autisms that rule ~*TeH sCeNE*~ stuck w/ mkv for hd when they switched from avi to mp4 (which took way longer than it should have).

The scene standard is to use MP4 containers if the audio is AAC.

Star War Sex Parrot posted:

yeah I think it's mostly related to how subtitles and multiple audio tracks are handled that ended up with MKV as the container because it literally does not give a gently caress what you add as a track to a file. i think you can mux a binary as a track in MKV, it doesn't give a gently caress. a player wouldn't know what to do with it, but MKV is content to take whatever you shove down its gullet

Nope, it's all about AC3 audio, which is standard in ATSC television broadcasts (because American standards are bad) and on BluRay discs.

Only the ~anime fansubberz~ and ~anime ripperz~ care about subtitles and and all that other crap, but they are not the scene, and they don't care about the scene standards.

okay pagancow or rly anyone else can you explain how codecs and containers and hardware decoding and poo poo works because even though i was pretty sure i understand i keep saying wrong things so idk

also if its just a container then why is it such a pain in the rear end slash impossible to get something from h.264/aac video in an mkv to the same in mp4 because for some reason nothing plays mkv's?? even though it supports the mp4 with h.264 and aac audio?? gently caress??? gently caress

feel free to go w/ a wall of text because im legit confused now i guess

Open the file up with AVIDemux, leave audio and video set to copy, choose MP4 as your format, and save the new file. Voila.

Of course it will give you a warning since the audio is most likely AC3 and you are trying to put that in an MP4 container which isn't ~standard~, but it will let you do it and software like VLC will play it. If you want to re-encode the audio, just change the audio to AAC and you're good.

pagancow posted:

yeah it doesn't help that ~ThE ScEnE~ thinks that everybody has DTS-HD 7.1 decoding equipment at home + the ability to monitor anything resembling surround sound on your desktop OS most likely running on a laptop...

BUT YOU GOT ALL THE DTS BITS!!!!

If you want re-encoded audio then get the SD MP4 versions. If you want HD then you might as well take the original audio as well since the video is already taking up so much space.

Install Gentoo posted:

scene rules are as much about making things hard to encode as they are about anything else

Ummm no. In this case the rules are about not re-encoding audio when you don't have to. The bitrate for the HD version is high enough that any space saved by re-encoding the audio wouldn't make much of a difference at all. Same reason why 2CD rips back in the day just used the original AC3 audio.

Today, if you want your re-encoded to AAC audio, get the SD version.

I just find it funny that ~TeH ScEnE~ requires you to encode your video as x264 even though all the things they list are basically "how the video is encoded already" but then "nooo dont touch the audio!!!", you'll spend 20 hours encoding a video, but nah dont even bother touching the audio.

i'm surprised they aren't like "yeah it MUST be nero aac encoder because its FREE1!!!"

http://www.sbytes.info/NFOwb.php?id=tbdx2k10

Because there is a LOT of space to save in re-encoding (and re-sizing) the video, not so much with the audio?

Also x264 is still the best h.264 encoder by far, but with AAC who cares? I mean they probably are using NERO but even FAAC is fine now.

yeah but this is pirate world where the thing that makes sense is to re-encode a video stream even though you're going to make it the same size, but not re-encode the audio so it plays on something other than your pirate pc codecs and an audio decoder that is probably more expensive than your TV.

Same size? What? The standard for 720p (downsampled) is a DVD and the standard for 1080p (not downsampled) is a Dual Layer DVD - far smaller than the original Blu Ray. The only things that are the same size are not re-encoded at all.

This is a TV show too so they were more concerned about finishing on time rather than quality.

Yes Disney used CAPS to scan in, but the computer didn't assist in drawing stuff for them compared to two examples you gave up there.

Ummm... everything in the first Teen Titans vid was done by Hand. None of the puppeting or flash tweened animation people were complaining about. Did you just watch the intro and nothing past that?

https://www.youtube.com/watch?v=EogJVdJwFjo&t=120s

Also this episode had a lot more effort put into the animation than most episodes of Animaniacs, though they clearly skimped on the backgrounds in comparison to Animaniacs. So yeah ~tradeoffs~.

Unless you were just talking about entirely digitally drawn animation versus the hand painted cels which were then digitally scanned in and digitally painted animation of the 90's?

pagancow posted:

I'm pretty sure it's computer assisted, as in some of it is drawn by hand, but then animations are tweened and repurposed. It's how they are able to get proportions to stay really nice throughout the entire animation, but it feels rigid and souless for the most part.

There are some custom animations in there that do feel hand drawn, but a run cycle or anything that loops is manipulated in the computer to save time. Traditionally, every animation had to be drawn by hand, and any looping was done in editing, because digital compositing was not time efficient back then. Today it is, and I see bits and pieces of it in the video sample you gave me.

Teen Titans was mid 2000s WB animation so I'm pretty sure they composited it digitally. Also of course the cycles were done digitally, as all editing was.

And all the tweening was done by underpaid Korean labor.

A guide for encoding through CLI (Command Line Interface)

GUI vs. Command Line (cmd)
The reason of using cmd is that it won�t restrict you. You can do everything that an encoder (x264.exe) can do. However, in a GUI you have to follow the GUI�s limitations. For instance you can�t use AQ-Method (3 and 4), as a GUI would not recognize / approve that command. As a result, you�ll either get an error or GUI will force the program to close.

And cmd is very easy to use and it�s very diverse. You just need to get used to it. (It gives a cool impression too xD. When you hear a hacker hacked an account, first thing you say is �awesome, he hacked it�, not why? or how? XD)

How to use Command Line

Things that you need to get before encoding via CLI.
1- ffmpeg.exe � Put the (.exe) file after Dling, no installation.
2- 10-bit, x264.exe (video and audio encoder) � Put the (.exe) file after Dling, no installation.
3- neroAacEnc.exe (only audio encoder) � Put the (.exe) file after Dling, no installation.
4- mkvmerge.exe (Optional) � DL it, Install it and get the (.exe) from there.

I recommed that you use 32-bit, or x86, versions.

Creating a Command (Line)

- Command Line Interface will do some work only when you give some valid command to the system.

- Commands can be written on notepad, any text editor, or CLI window.

- If you are writing the commands on any text editor, it will probably be saved in (.txt) format by default. That won�t activate CLI. You�ll have to save your written code in (.bat) format. To do that simply hit �Save as� and at the end of the filename add (.bat) extension.

- If you run (double click) any (.bat) file, the commands written inside the (.bat) files would be forwarded to system and if they are valid they�ll be processed, otherwise CLI window will be closed automatically without doing anything.

- It means that all you need to do for CLI-encoding is write valid commands, save it in (.bat) file and run it later on. Encoding will start as according to what�s written in the (.bat) file.

General Info of writing Commands

I won�t talk about heavy and complex commands, rather just skim over general idea of command formatting.

code:

Executable_file(.exe) commands_specific_to_that_(.exe)_file

Executable file could be anyone like mkvmerge.exe -or- x264.exe
To know what kind of commands / features can be used for a mentioned (.exe) file you need to have some knowledge. Like:

code:

neroAacEnc.exe -ignorelength -lc -q 0.5 -if - -of encoded_audio.aac

It can be gained via browsing internet, personal experience, and logfiles etc.
As this is a guide, I�ll make sure to let you know the requisite commands to encode a video file.

Settings from Logfiles

Well, every (.exe) file has a logfile which explains the settings, or features, that can be done. To get the logfile of any (.exe.) via CMD, you�ll have to make a short command. This will also serve as a practical of making a (.bat) file.

Make a new folder, somewhere nice. Place following files in it.
- ffmpeg.exe
- x264.exe
- neroAacEnc.exe
- mkvmerge.exe

Open a notepad, and write this:

code:

x264.exe --fullhelp
@pause

Save this file by hitting �Save as�. Name it whatever you wanna name it, but select the extension (.bat); after that, save it in the same folder. It will be appeared as a �Windows Batch File (.bat)�. Run it by double-clicking. You�ll get something like this.

code:

x264 --fullhelp
x264 core:120 r2120 0c7dab9
Syntax: x264 [options] -o outfile infile
Infile can be raw (in which case resolution is required),
or YUV4MPEG (*.y4m),
or Avisynth if compiled with support (yes).
or libav* formats if compiled with lavf support (yes) or ffms support (yes).
Outfile type is selected by filename:
.264 -> Raw bytestream
.mkv -> Matroska
.flv -> Flash Video
.mp4 -> MP4 if compiled with GPAC support (yes)
Output bit depth: 10 (configured at compile time)

It will prove quite eye straining at first, as there are hell of settings etc. Once you get used to it, it�ll become a routine work.
Good news you don�t have to go through this necessarily, I�ll tell you what commands to use to encode a file. Rest is for your own interest.

Commands for Encoding a File

I�ll keep things focused to CLI so I�ll just tell what command to write rather than detailing about why using what features etc.

a) Video Encoding � Command

code:

x264 --level 5.1 --preset veryslow --tune animation --crf 23.0 --min-keyint 12 --scenecut 45 --bframes 8 --b-adapt 2 --ref 10 --weightp 2 --qpmin 10 --qpmax 51 --qcomp 0.6 --rc-lookahead 40 --direct auto --aq-mode 1 --aq-strength 0.8 --merange 24 --me umh --subme 10 --trellis 2 --psy-rd 0.40:0.60 --acodec none --output "Output.mkv" "Input.mkv"

- Input.mkv will be the file you want to encode.

- Output.mkv will be the file (video only) you�ll get after encoding is done. Name it whatever you want, except that it shouldn�t be the same as Input.mkv name. If the output name is same it will replace the input.mkv immediately and you�ll lost your input file resulting in no encoding and lost of input file.

Usually, you can encode audio by x264.exe, but I have disabled it. I use neroAacEnc.exe to encode audio separately.

b) Audio Encoding � Command

code:

ffmpeg -i Input.mkv -f wav -| neroAacEnc -ignorelength -lc -q 0.4 -if - -of Output_Audio.aac

- Input.mkv is the same file you used for Video Encoding.

- Output_Audio.aac will be the file (audio only) you�d get after audio encoding.

c) Merging files � Command

code:

mkvmerge -o "Final_File.mkv" --language "0:jpn" --track-name "0:Hi10 Encode @ CRF 23" "Output.mkv" --no-chapters --language "0:jpn" --track-name "0:2.0 AAC-LC @ 0.4" "Output_Audio.aac" -A -D --language "2:eng" --track-name "2:Styled Subtitle (.rear end)" "Input.mkv"

- Final_File.mkv will be file (including video, audio, subs, fonts, chapters) you�d get after merging.

- Output.mkv is the file you get from Video Encoding.

- Output_Audio.aac is the file you get from Audio Encoding.

- Input.mkv is the file you already have. (Source file you wanted to encode.)

Tested did a huge effortpost on the Sony CRT monitor and the XRGB Mini and I think they've basically been lurking this thread. They also explain 240p thusly:

"Older consoles manipulate the NTSC timing to force the lines drawn on screen to overlap, rather than alternate," writes Daniel Corban, who, like Reich, is self-taught in the intricacies of video hardware. "This is where the term 'double strike' would originate; the lines are literally being repeatedly drawn on the same physical area of the tube. This is also what creates scanlines. On a digital display, the signal is simply handled as a 240-line progressive signal, hence '240p.' "

Jimmy Carter posted:

so is still better than netflix (ignoring the MKV comedy)?

Well it depends since :filez:

people do whatever the gently caress they want. Make a 720p 700MB encode of a 2 hour movie? WHY NOT

But assuming we're talking about something up to ~scene standardz~ then that would be about 8GB for a 2 hour 1080p movie, which comes out to roughly 4GB an hour (less if the movie is a bit longer than 2 hours obviously), which is about 67MB a min, which is 1.12MB (bytes) or 9mb (bits) a sec, which is indeed 50% more bitrate on average than Netflix or Youtube will give you. And that's not even taking into account that they use high profile, rather than baseline, and have standardized on x264 as an encoder (though I do not know what Netflix and Youtube use)...

So yeah :filez:

will give you better quality as long as they obey :standardz:

Recording videogames that can't maintain a completely stable framerate (i.e. all of them)

Also there are tons of TV shows that were recorded on film and displayed on video with 3:2 pulldown but have certain sequences where they were sped up to 29.97 or where effects/transitions were done at 29.97
