   Hi,

   Recently a having problems with the MKVmerge, previously I try to mux one of my .mkv file, and try to crop the video using parameter 0,6,0,6 (video at 1280×544), but the video somehow seems stretch, so i also encoded this files using MeGUI previously with cropping the video as well with same setting 0,6,0,6 and the video were resize to 1280×528, I try mux with this setting, changing the display weight and height from 1280×544 to 1280×528 with cropping setting at 0,6,0,6 and works, but suddenly on second attempt on same file a few hours laters, MKVmerge no longer able to change the display from 1280×544 (i’m using same setting that works previously), instead when i look at the file mediainfo, below:

   Display aspect ratio : 2.40:1
   Original display aspect ratio : 2.35:1

   The working file (1280×532) AR were 2.40, so I try to uninstall MKVtoolnix and all preferences, since I would assume, it will store all settings permanently. But no luck, while I install it again, somehow when adding file, MKVmerge do remember the last folder when I added file. I don’t know if this is related to the problems i having, but can you help me here. Thanks, and keep doing the great job

      I’m sorry, but I cannot really help you with such a problem. mkvmerge only sets header fields and does not modify/re-encode the video. Aspect ratio/stretch problems during playback are therefore nothing that’s due to mkvmerge.

         and that is the problem, i mux the video using MKVmerge changing the display height and weights with cropping video, and works, and few hours doing a second attempt, it’s not working anymore.. or perhaps my first attempt was just a minor bugs?

            No idea, sorry.

               no problems, sorry to bother you, you’re doing a great job here :-)

   Hi,

   Mkvtoolnix source code can runing for window with visual C 2010?
   Thanks!
   1. mosu Post authorJune 21, 2011 at 08:24

      I don’t know, sorry. I don’t own or use MSVC.

      Other users have had success with MSVC in general (not necessarily 2010), but that required a couple of changes and addition to the MSVC project files. Those project files were contributed by others, so again I cannot really tell you whether or not they’re stils supposed to work.

   Mkvtoolnix does not support ofr formats.
   1. mosu Post authorJune 21, 2011 at 09:08

      True, and I don’t even know what OFR is supposed to be. So most likely it will stay unsupported.
      1. M June 21, 2011 at 09:14

         ofr is a lossless format.

         Use it to keep a good sound quality.
         1. mosu Post authorJune 21, 2011 at 09:17

            Interesting. Well, mkvmerge already supports three lossless formats (FLAC, TTA, WavPack). None of those seems to be used much, and I don’t see much of a reason to spend time on yet more lossless and unused formats.
            1. M June 21, 2011 at 09:24

               ofr files without taking up too much pressure space.
            2. M June 21, 2011 at 10:36

               Lossless format for ofr the smallest format
5. M June 21, 2011 at 11:03

   I often use the mkvmerge GUI package audio and video file formats do not support ofr very convenient.
6. bseos June 21, 2011 at 18:00

   Could you please include an option with mkvmerge GUI to save the changes to the original file instead of writing to a new file please.
   It would be a great time saver when working with alot of large HD files.

   Also, does “mkvpropedit” allow me to switch the order of audio files within a mkv container?
   1. mosu Post authorJune 21, 2011 at 21:53

      Saving to the same file is technically impossible, or at least so unfeasible that I’ll never implement something like that.

      To the second question: “it depends”. You can exchange the track numbers, but that won’t re-order the track headers physically. Then it depends on the players and in what order they present the tracks. If they sort by the track number (which they should, but which they don’t always do) then yes, mkvpropedit can help you. If they sort by the position they find the track headers in then no, mkvpropedit cannot help you there.

   I’m sorry if this isn’t the place to leave this questions but I just wasn’t sure where it actually belonged. I was recommended your software to do a conversion but when I run it my firewall “online armor” suggests there is a key logger involved. I assumed there was a reasonable explanation but a google search turned up nothing and thought you might be able to put my mind at rest before I start using this. Any info you can give would be great. Thanks

      See http://www.bunkus.org/videotools/mkvtoolnix/faq.html#virus_in_installer

      The answer also applies to cases where spyware, trojans or other malware is supposedly found in my files.

         thanks for the quick reply
