    I've been wanting to throw in some of the old anime I never got to watch onto my ZuneHD.

    Formats they are in are: .mkv, .rmvb and .avi.

    It is a freakin variety...
    All are subbed and was wondering if there was a converter that could convert these videos to .mp4
    While in the process, bringing the subs with it when it were to translate.

    And one that can convert more than one video...

    I am hoping it is a free choice,
    but if it requires charge and you know a way to get it without paying,
    PM me [​IMG]

    I need this by this weekend!

    +1 on this.
    I've been wanting to find something that can convert .mkv properly to .mp4 format to burn to DVD but every time I do it, you can't see the subtitles properly.

    Now there are 2 people!

    Can you remind me why people choose to use those formats ?
    Why can't they just use .avi or something more common...
    Maybe it has something to do with their subtitles...
    I have no idea since I know nothing xD.

    One thing I really want to convert is my Gundam Seed + Destiny episodes.
    They are all in .mkv and are english dub.
    I want subtitles to be cut off since I can fully understand it xD.
    So that's one thing I am interested in.

    Super Converter is good and free. The only problem is that you need to know what settings you want as there's not a lot of presets built in.

    I don't want to sound like a jerk. But I really recommend a NMT (Network Media Tank). You just connect it to your (HD)TV and you're ready to go. I have a Popcorn Hour A-110 and it plays virtually ever video extension/format you can imagine! It's really a must have when you want to watch your entire Anime collection (in glorious 1080p HD!)

    But if you want to watch your videos on the go I don't really have a recommendation. There is still no portable mediaplayer that plays every extension. Maybe the future will bring one..

    Pfft. It would just be easier and much cheaper to hook up your computer to your TV.

    EEEk Forgot the name of it it was awesome ill edit the post really quickly after i remember
    FOUND IT

    EncodeHD best batch converter i ever used really great only bad thing is that if you convert with highest video and sound quality takes a long time

    http://dcunningham.net/tag/encodehd/

    Also theres encode360 found under mediatools which is apparently good for your zune

    you could try Media Coder
    There are few already created destination profile (like PSP, iphones, etc.)


    It's free, but I think they recently add an sort of badthing-ware (not a spy, but it ask for you to install other software from their affiliates), just refuse that while installing.

    Crash course in video as it pertains to this topic, apologies for the general incoherent ramblings that follow but it is about all I can do to stay awake right now.

    containers- various ones exist including avi, mkv, wmv, ogm, mp4 and rmvb (I shall resist the temptation to spit as I would only have to clean it up afterwards). They exist to make the life of decoders easier- AVI stands for audio video interleave and as the name implies weaves audio and video together so as to reduce the need for random access of files on a disc but it is showing how old it is with poor support of newer standards and lack of real subtitle support. MP4 is a more official container from big standards types (it is also patented rather harshly in places that consider software patents a good idea) while MKV is a somewhat more open standard with great support for just about everything so it caught the eye of most encoders fairly quickly (especially among the anime scene) however hardware support is not as great as other formats.
    Note and note well that the container/extension has nothing to do with what it contains.
    The act or removing a stream (audio, video, subtitles or whatever) from a container is called demuxing while the act of sticking stuff into a container is called muxing.
    For MKV the tool pretty much every uses (whether they know it or not) is MKVtoolnix:
    http://www.bunkus.org/videotools/mkvtoolnix/ (MKVextract is the tool to pull things out, it has a GUI called MKVextractGUI. MKVmerge makes the files and can take most forms of input).
    For MP4 there are several choices but I suggest MP4box, it has a GUI in the form of YAMB:
    http://yamb.unite-video.com/
    For AVI it is a more general tool but avidemux is good:
    http://fixounet.free.fr/avidemux/

    RMVB is probably going to be a pain (there is a reason nobody likes them), they will almost certainly require encoding in a proper format.

    OGM for many was the precursor to MKV and a fair bit of anime is still out there in that form.

    There is nothing stopping you from demuxing from MKV and sticking it in a MP4 container, indeed unless you have extra requirements (needs to be below a given resolution or something) I suggest this over encoding again (encoding is lossy in these situations and encoding several times is never great).
    MP4 is about as good as MKV when it comes to support for various formats but it falls over when it comes to subtitles. As a rule though anything beyond trimming the video or adding video onto the end will mean you need to encode it again.

    standard- a way of encoding video and audio. It gets more complex very quickly but MPEG4 is a broad catch all name but includes part 10 aka H264 aka AVC, while part 2 is used in the likes of xvid and divx. H264 is more powerful (better compression for the same file size) but it comes with a resources penalty and being somewhat newer is not quite as widely supported unlike part 2.
    Audio comes in several formats but the big ones are MP2, MP3 (actually part of MPEG1), ac3 (DVDs mainly but people sometimes avoid reencoding it), aac (maybe not the best audio standard but as good as it gets outside of lossless and in common use) and WMV (varying, competitive with all formats). Note that the MP4 contain can and is used for just audio (sometimes appearing with the extension m4a but that is just a rename).

    subtitles: come in softsub and hardsub form. Softsub is a bundled extra file which in the case of MKV sits inside the MKV file but for most other formats it sits outside it.
    Hardsub is burned into the video- if it sits in the edges you can just crop the subs out but otherwise you are not really going to be able to remove it easily (if you are especially bored you can use some of the logo removal filters)
    Softsubs come in 4 main formats (there are hundreds mind)
    srt- subrip text, falling out of favour but still many around. Very basic format with nothing all that special.
    vobsub- the sub and idx file you might see when you get a video. While subrip is text based DVDs use pictures and as OCRing stuff into text is a pain many people just dump the subs into this format. Not that common in anime circles (even DVD rip groups) but everywhere else it is now probably the number one format.
    The other two I will merge, they are SSA and ASS (substation alpha and advanced substation alpha). They use an odd XML like format but can do fun things like place themselves anywhere on screen, do karaoke subs (note that while it can and may have started as such some anime groups hardsub this into the intro and so a softsub the rest of the time), change fonts and colours and the like.
    If you must convert them then three applications I use are subrip, subtitle workshop and subtitle creator (mainly for DVDs but worth having anyway).

    If you are encoding you can burn subtitles in with many things but http://forum.videohelp.com/threads/214768-...h-virtualdubmod is a good intro to it all.

    As you have found out hardware decoders (especially big name ones) are usually troubled by anything slightly deviating from their known parameters (it is why stuff like an original xbox with XBMC is still worth a look in) and this can stretch to parts of the whole spec (earlier ipods (not sure about later ones) notably left out support for some of the better compression variations of AAC like HE-AAC). It is better than it was some 6 or so years ago but still far from acceptable in my opinion.

    Never pay for a general encoding application (some of the more specialist stuff is a different matter) as most are based on open source stuff you can find just as easily. My choice is megui or one of the ones in http://forum.doom9.org/forumdisplay.php?f=78 but they may not be quite as easy to handle (for what it is worth this side of good AI you will not see any "one click encoder" work as well as someone who took a few minutes to play with some settings, good applications there though will have some support for the various devices and their limits).

    wow, lot of text here [​IMG]

    Thanks for the MP4 demuxer. I didn't have one.

    I would like to add few things :

    • you said sometime there are m4a for audio only, there is also m4v for video only.
    As the streams can be extracted independently of the container, they usually have an extension with ...a or ...v (instead of simply .bin or .raw).

    • For rmvb, the video stream is compressed over the frame rate instead of the usual picture quality, dropping frames when the action is less visible.
    The problem when converting it to another format result in a shorter video, de-synchronized subtitles and audio.
    You need to force the framerate to reinsert the dropped frames.

    I dealt only one time with rmvb, and I used Avisynth with the convertfps command.
    Code:
    DirectShowSource("L:\My sassy girl\Track1.rmvb", fps=29.97, convertfps=true, audio=false)
    it will output an un-encoded stream, so you need to re-encode it directly to something else (like xvid, or h264). You will lose quality though, but you can't help :/

    I used audio=false, because I already had the audio stream in a separated files (to create the vob for DVD video, I needed the streams independently). I think it's better to work with both stream separately when working with rmvb.
    So you can extract audio stream (virtualdub mod should work great for that), and remux it to the newly created .mp4 without re-encoding, at least you will not loose audio quality.


    FAST, maybe you have a better tool for rmvb ? something more noobfriendly than scripting with avisynth ?

    Afraid not Cyan, I purposely avoided mentioned avisynth in that post (avisynth is my go to tool for most video work but noobfriendly it is not) but it is the only way I have really been able to do anything with RM stuff that produced a result worth having. Others if you add denoising and other filters like mvtools (and watch your computer grind to a halt) you can get slightly better VFR to constant frame rate than the stock avisynth stuff, I have not tried ffmpegsource yet which might be better but my life is rather fortunately free of real video these days beyond the odd streaming video.

    Even if you did demux them with something like http://www.videohelp.com/tools/RMMuxer then you would probably only end up with RM files (a few people crammed some odd stuff in there).

    Others- if you must have something with RM in it try http://www.free-codecs.com/download/Real_Alternative.htm before fiddling with the nastiness that is the official player.

    damn...
    is converting a video while bringing those files that hard!?

    honestly,
    if i have to,
    i can just take the video right now without subs.
    when i use VLC,
    it gives me an option of using or not using the subtitles.
    i guess that means it was a soft sub right?

    other than that,
    i need a converter that can convert multiple vids...
    nyeh...

    Yeah if you can turn off subs, that means they are softsubs. Or there are two video streams which would be crazy.

    I've had a good experience with PSPVC for converting videos with softsubs, not sure what else is good.

    Yeah other way would be to get a program that handles .ass or .ssa format (Most common sub formats) and hard codes them.
    Either way, you'll have to convert from softsubs to hardsubs else it probably won't work

    Also, don't mention VLC, you'll get lynched for that [​IMG]

    I think Media coder I linked can convert multiple video (from batches).
    unfortunately, is needs firefox and want to call home at launch u___u
    Spyware is bad, if you use a firewall you can refuse calling home.


    But as FAST said, it's better to demux/remux the stream without converting or re-encoding them, if you only need the container to be in .mp4 format.
    If your player doesn't read external or soft subtitles, you will have to re-encode and loose video quality :/

    fuuuudge...
    i don't think the ZuneHD can't read soft subs...
    AFAIK, it doesn't seem possible,
    but I haven't tried.

    i have one. its called Free Zune Video Converter. its how ive converted all the videos ive gotten off of youtube converted and then put onto my zune.

    it also converts them into music files, and other formats to choose from so if u have other than an zune, it can convert it for that player too.

    if you guys want i can email the folder to you or try to put it on a filesharing site so everyone can have it.
