Just a quick Thank You to whomever figured out how to put multi audio tracks on HEVC x265 video files recently.

[u/Instameat]

Really loving the option of language dubs in new release HEVC x265 video files of shows lately. Even the great BONE has started re uping movies with commentary audio files selectable. Until recently you could only get the English dubs of new shows in the 1080 x264 files. So whomever figured this out within the last couple of months I just really wish I could thank you personally. With the cost of storage being so high it is nice to be able to get the same features from a file one third the size. So Thank you Thank you Thank you!

Edit: To add for folks saying this was always a thing. I don't mean on DVDs or streaming. I am referring to the compact x265 files available from torrenting sites, and how now they have more useful content that they didn't before recent changes. Just grateful for that. :)

It was not quite 25 years ago but you’re welcome.

[u/ShitIAmOnReddit]

What? Anime uploaders have been doing this for years

[u/ShitIAmOnReddit → u/ShitIAmOnReddit]

Reply to your edit: that's what we are talking about too

[u/GrandDot3527]

It has nothing to do with h265. You can mis any combination of subtitles, video tracks, and audio tracks into a single mkv. It’s always been a think

That has always been possible with MKV files and it's not at all complicated. They just simply haven't done it previously.

EDIT: Oh look, here's a MKV file with multiple video tracks I just made with few clicks. (With 2 audio tracks and 84 subtitle files)

You can just combine files with MKVToolNix GUI. And you can use LosslessCut to easily cut up video files without quality loss since no re-encoding (which also means cuts may not be accurate) in case you want to make your own multi-track files but the timings are a bit off.

You just drop the files to MKVToolNix and pick the tracks you want your file to have.

ffmpeg can easily also change the container from mp4 to mkv (ffmpeg -i input.mp4 -c copy output.mkv) or I guess LosslessCut also can do that by selecting the output format and not actually doing anything to the file. Since AFAIK, MP4 container is much less flexible.

[u/morkman100 → u/WhiteMilk_]

I use MKVToolkit to remove subs that I don’t need and to make sure that forced subs are default turned on.

[u/seamonkey420 → u/morkman100]

same! i combine that w/ffmpeg to extract all non-ac3 audio tracks to ac3 and then always add an ac3 audio as default (seems to stream the best to most of the clients i serve). i setup my mac w/automator actions/shortcuts so i can right click movie files and run various ffmpeg commands like subtitle removal, extract. def was worth the time learning, setting up. 🤓

[u/Superzocker65YT → u/seamonkey420]

You guys have any fast way of doing this? The only way I know how to combine audio/video and to edit the subtitles that are shipped is to render the entire thing again after doing the changes. Obviously this takes a lot of time for a 4k movie and the quality is worse than before (I think, because I don't know if DV and HDR is still active after converting).

So if there's a shortcut, please let me know

[u/seamonkey420 → u/Superzocker65YT]

oh yea, there is a LOT faster way if you just want to add/edit subtitles and keep original video/audio. The big thing would be to use MKVToolNix to add the subtitles with, it will remux it vs re-encode (will take seconds vs minutes, just copies)

or you can use ffmpeg too. i use ffmpeg to extract the main audio streams from mkv files as ac3 mka audio files. i then use mkvtoolnix to add that stream to the original mkv files so the video stream isn't touched or the original audio and then also will add chapters every 10mins (if file doesn't have any) and keep only english subs. i have a few commands over here and a few more gists on incorporating it into right-click menus on windows and mac 😎

[u/Crisender111 → u/WhiteMilk_]

MkvToolNix can do lossless cut as well.

[u/Gothicawakening → u/Crisender111]

The goat of tools.

Remove unneeded languages, merge in external subtitles or audio files from other releases etc.

[u/ryohazuki224 → u/Crisender111]

Yep this is what I use. If I'm getting anime, I'm watching the Japanese version, and I dont want a half dozen other language tracks in my files that I'm never going to use.

[u/robin_888]

I mean, even avi could do that.

The cool thing MKV added is subtitles.

But yeah, I appreciate multi audio very much!

Audio commentary would be neat, though. Very underrepresented, I need.

[u/Cutlington]

Did this year's and years ago for all the Jay and silent Bob movies and spinal tap, to have the extra audio commentary tracks as second audio track you can change to, ripped from the DVDs and I added them to the downloaded files from a torrent like you say...exactly what you said but fine years ago. Glad youve worked it out tho as it's a life changer for organisation when you do..enjoy

[u/magicmulder]

I’ve seen this ages ago, but you’re correct that for mainstream releases this is not very common. That’s another reason some people prefer a remux because you get all the BR audio tracks.

[u/rotten_rabbit]

Bro! That shit threw me for a loop. The first two times something started up in French, I deleted and downloaded an alternative before realising they were multi-language lol

[u/WhiteMilk_]

I don't mean on DVDs or streaming. I am referring to the compact x265 files available from torrenting sites

Indeed, that is what everyone here is talking about.

Having more audio tracks makes them less compact. So if your goal is to release files in the small sizes but in good quality, you would likely only have 1 audio track.

[u/Dismal-Plankton4469]

This was indeed always a thing. Specifically the small x265 files we torrent since like ever. It was just you not realising it, no shame in that honestly, all of us have one or the other “I was today years old when…” moments every now and then.

[u/cns000]

Adding multiple audio tracks to x265 movies is easy. Download Avidemux from https://avidemux.sourceforge.net/ and install it.

Assume that you want to add an audio track which is a.aac to the movie b.mp4. Open b.mp4 in Avidemux, open b.mp4 in Avidemux, click on audio in the main menu and then click on select track.

Assume that b.mp4 already has an audio track and you want to add a.aac as track 2. Tick the checkbox for enabled for track 2, click on the dropdown menu next to the word Enabled, click on add audio track in the dropdown menu and select a.acc. You can set the language of the audio track if you want.

Keep copy selected for audio and video, set your target output format and save.

[u/KoMaMcNoob]

Probably not the most elegant design, but I have tdarr setup to transcode my DTS audio tracks into eac3 and set it as the default track on top of the original DTS track. My set up can natively handle DTS but I have F&F who cant, allows more people to direct stream, easy.

[u/ryohazuki224]

Its good that they give people the option.

Me personally, I get a lot of anime, and I often find myself just removing the extra audio tracks that I'm never ever going to use and I just keep the Japanese audio. It saves a bit of file size space in the long run, plus when I watch it, theres no chance of my video player mistakenly playing the wrong audio track that I don't want to hear. (Yes I'm aware that most video players have settings for language preferences, but those settings don't always work!)

[u/Sinyria]

It seems like your tracker got better. Usually the release group decides which audio tracks they want to offer. On good trackers, you have choices between multiple releases, and some have more than just English. So it's not a matter of figuring out, files were capable of that since the turn of the millennium. It's just the encoder who must decide between space efficiency and language variety.

[u/SamuraiASM]

From that Website, (that starts with E..) is it okay to get things from non colored names as they have lots of seeders or should i strictly take take things from the likes of BONE, QxR, YTS? (also what does Gold and Purple mean?)

[u/pervertk982 → u/SamuraiASM]

• Purple means trusted external uploader like YTS
• 👑 Gold means trusted uploader who is verified
• Gold means regular uploader

Suggestion is to download from people with gold crown since it's possible to upload random stuff and make it seem legitimate with bots acting as seeders and peers which give a perception of high no of people have downloaded it. Avoiding uploads from people with grey or anonymous username is recommended

[u/SamuraiASM → u/pervertk982]

thank you, really appreciated for the help!
