MKV to m2ts Stretched

[anonymous99]

I have 2 more MKV files which arn't coming out in widescreen once I change the container with mkv2vob so that means I end up with an output video which has lines down each side.

My question is, how do I change containers or even re-encode the file and keep it the same?

I have looked for a smooth answer but havn't come across anything too useful as yet.

It probably used container level signalling in the .mkv to stretch the display, or encoded anamorphically using different SAR value from 1:1, and mkv2vob assumes 1:1 so the display is distorted

If this is for PS3, you probably have to encode it using 1:1 pixels and resize it to the desired display size for the proper aspect ratio

You could use xvid4psp or ripbot264 to do this

I was trying to use xvid4psp earlier today, I created a restore point just incase I didn't need it due to having to install FrameWork 3.0 and not wanting to, I had done everything asked and whilst I entered the file into the program, it kept on closing itself after I opened the file and it finished Caching the file, I don't know why?

Just checking out ripboy264 now but I don't know if it will work, very sceptical at the moment as nothing seems to be working.

There has been a few bug reports from the newest version 1.13.0

Try using and older build e.g 1.12.0

I had problems with xvid4psp and hadn't tried RipBot yet, however I have just installed it and everything else its asked me to install and it's still telling me that FFDshow is not installed, event though it is!

I might try using an older version of xvid4psp if theres one available.

How do I go about changing this file to an m2ts file without it changing the aspect ratio?

Also, how long roughly could it take if anybody knows?

You need to provide more information on the source video. Open up the video in avinaptic and post the video display information here, it might look like this

Resolution: 1920 x 800
Frame aspect ratio: 12:5 = 2.4
Pixel aspect ratio: 1:1 = 1
Display aspect ratio: 12:5 = 2.4

Did you get ripbot or xvid4psp working yet? Another option is megui

The two files both have the same Resolution, Frame aspect ratio, Pixel aspect ratio and Display aspect ratio.

Resolution: 720 x 516
Frame aspect ratio: 60:43 = 1.395348
Pixel aspect ratio: 4:3 = 1.333333
Display aspect ratio: 80:43 = 1.860465 (~1.85:1)


If there is anything I can do to put these in an m2ts container that would be great as I've exhausted myself just looking for answers in google, it's hard to search for something when you don't know the specifics of what you need to do.

From this thread: https://forum.videohelp.com/topic347942.html

I notice that scift said he solved the problem but doesn't state exactly how, he does say he had to re-encode it, but he doesn't say step by step what he did?

At the moment I am running one of the files through mkv2vob and have selected under Transcore "always" hoping that this might make a difference but I'm not so sure it will.

If you just wanted to swap containers , you could use tsmuxer to put it into .m2ts - this would only take minutes instead of hours re-encoding, and there would be no quality loss because you are not re-encoding, but the aspect ratio will likely be off. Also if the video stream is non compliant, it might not play on the ps3 (e.g too many reference frames, too many b-frames etc. etc...)

Otherwise you can use xvid4psp to output to .m2ts or mp4 which both will be accepted by ps3 . You want to resize it to 720x384 (1:1 pixels) to preserve the 1.85:1 DAR, and keep mod16 compliance

Cheers

I know how to use mkv2vob and tsmuxer but the problem is the aspect ratio being changed and alot smaller on the output file.

I have spent a good deal of time trying to use xvid4psp, whilst it kept crashing (I don't know why, no error was given, it just closes when it feels like it) and I have kept on trying to use it I finally got it to work, then realizing all the work I had put in to change the audio hadn't paid off because it wasn't what I needed to do! lol

Are there specific settings I would need to change in xvid4psp and if so, where would they be located in the program?

I just want to be specific this time around so I know exactly what I am doing, I have installed this program 3 times in the last day (with FrameWork 3.0 each time too) and each time it never paid off.

I don't mind re-encoding if that is what I have to do, I would just like to keep the output file size simmilar, I don't mind it being 2gb from a 1.5gb file as this is the usual from mkv2vob and isn't so bad as it holds the quality nicely.

That's what I said - you will probably have to re-encode it.

If ps3 accepts par information in mp4, you might be able to do it that way with yamb. You would use mediainfo to note the fps. Extract the audio & video with mkvextractgui, then use yamb to re-mux (no-reencoding) the audio & video into .mp4 . In the properties tab, you would enter the PAR (enter the same value given in avinaptic above), and the fps. While software media players will accept this, the ps3 might disregard the aspect information. Try it if you want.

You don't have to use xvid4psp. You can use ripbot264, megui, staxrip etc.... there are dozens of programs they are just front ends. I just suggested xvid4psp and ripbot because they are easy to use

I gave the wrong size above, you should resize to 960x512 frame size, with 1:1 pixels if you are going to re-encode it. Re-encoding it will work 100%.

I'll make it super easy for you:

1) Install avisynth
2) Write this in notepad and change the extension to .avs

DirectShowSource("myfile.mkv")
LanczosResize(960,512)

3) Use megui, using the ps3 profile, encode the video
4) Use mkvextractgui, extract the audio from the mkv
5) Use megui's mp4muxer in the tools menu, or yamb to make your new mp4
6) This assumes that your audio was complaint (e.g. aac , not something else), otherwise you to re-encode that as well. Use mediainfo if you don't know

DONE!

Thanks for helping, this seems like the first 100% clear answer I have had in ages.

I'm not going to try again so soon, but when I do I will be doing everything you have mentioned.

Thanks again, you've been a great help.

I listed some steps above. If you can't get megui or xvid4psp to install/work list the error message.

The problem with xvid4psp is that it closes with no error message, just randomly closes when it feels like it. lol
