Converting issues

[Mystes]

Does someone know how can I convert Matroska files into .mp4? I searched, but there weren't any 'free' ways for this.

Anyways, why is MKV format used?

In short, it's the least restrictive of the video formats but the least supported because companies don't want you to have that much freedom

HOw about converting?

At least one of those is going to work, probably

I'll try rebox.NET then.

I'll try rebox.NET then.

If it works please let me know, I have been searching for one without to much success, I have tried MKV to Avi Converter and SUPER and sometimes they work and sometimes they don't, failures over conversions, audio not in sync with video, no subtitles, those are some of the regular problems with this.

If you have the time and CPU to do it and a free PS3, you can download Ps3 Media Server, and with that if you copy any video from your computer through Ps3 Media Server it will end up in a easier format to handle, just a little big in size

Like AVI, both MKV and MP4 are containers and not compression formats (such as WMV). Though not exactly the same, you may think of them as compression archives like ZIP and RAR.

If you simply want to replace one container with another, there is no need to reencode the video and audio. Just demux (extract) them out as raw streams. Along with the timecode information, mux (repackage) them into one single MP4 file. This process is called remuxing - lossless conversion from one container to another.

The process is quick and efficient. Even with this old IBM laptop I am using with a slow Pentium M processor, I can remux one episode in less than one minute. But there is one downside: there is no standalone free/paid software that does this, so you need to get a batch of command-line executables and write a simple script for it. (All softwares that claim to convert MKV to MP4 in one click involves reencoding, which inevitably maximizes conversion time and minimizes output standard.)

Alternatively you may do everything manually by fiddling the command line, though it is certainly a headache if you have a 52-episode series waiting in the queue.

If your desired conversion involves reencoding, such as turning a Theora FLAC MKV into an x264 AAC MP4, then yea get yourself a high-spec PC or prepare to wait for eternity for the process to finish.

Frankly I hate MKV since I use the Sony LCD TV in my living room to watch anime.

Anyway you may google these, read the relevant online tutorials, and download the required executables and libraries to start your first remuxing exercise:

Remuxing:

Demuxing: mkvtoolnix
Muxing: mp4box
Timecode: DtsEdit


Reencoding (on top of the remuxing tools)
(Depends on the format of the source and target. Below is an example of stuff you need to reencode a FLAC stream into AAC for PS3/Sony Playback)

FLAC to WAV: Flac
WAV to AAC: neroAacEnc

If you just want a program to convert video files from one format to another, I suggest using "Any Video Converter." It is easy to use, quick, and relatively painless without having to worry about whether the subs will follow you in the conversion or not. Also, best of all, it is free. The last thing I would note about this program is that you can play with the quality of the video and audio, if you would like to improve the performance of the video for your needs.

I'm using this, but does not work with MKV

It 'works', but it's really, REALLY slow. I think in 15 minutes I haven't gotten even 40% of an anime short episode converted.

@Dorankeo I'll try this method for now.

Really? It should work with MKV. That is odd...

I tried, but maybe it's because I have v.3.0.7?

[ainsoph9]

Upgrade it. It should work then, I would think.

I also think so...

...

...time to find a keyg*n.

[ainsoph9]

Umm...the program is legally free. Finding one of those at this point is retarded and useless.

Nah, it's only 3 mins maximum.
