TsMuxeR files sizes?

[Ghitulescu]

I've searched, as usual, the forum before asking this question - no relevant topic found.

So I have an MKV file having 1 video and 2 audio streams. All together a bit less 5GB. So I thought that taking out one audio, like in DVD Shrink, the result would fit one DVD5.

Wrong. Having 1 audio track taken out, the result was greater than the original MKV:mad:. I've made a second take, with all audio streams, and the result was about 350MB larger than the original file.

This was my first use of TsMuxer, but I'm confident I've done nothing wrong or "special". Is there any explanation or solution?

Thanks,
Ghitulescu

So you're saying that the m2ts file authored by tsmuxer without one audio track from the mkv is larger than the original mkv? If so, that could very well be possible. Muxing to m2ts has about 7% overhead.

I've found this post -> http://forum.doom9.org/showthread.php?p=1092443#post1092443, almost by accident.

So 7% overhead for about 5 GB is really about 350 MB. :). But why 7% overhead? Seems a lot to me. For DVD I think is less than .1% (I don't know now, but I never had a problem authoring a DVD from ESs, even if I was close to the 4700000000 B limit :rolleyes:).

Just re-encode the source with a desired bitrate to hit the target size while including m2ts overhead.

That was also my first idea, however I prefer to keep reencoding as the last solution.

Actually, what bothered me was the fact that the remuxed size couldn't be accomodated on a DVD5 for testing on a BD-player - so far I know, no eraseable/rewritable DVD9 exists.

Hi!

I believe you should be able to use "MKVMerge" (no conversion to .M2TS or .MTS) to accomplish this...

Nope!

"NAME
mkvmerge − Merge multimedia streams into a Matroska file
SYNOPSIS
mkvmerge [global options] −o out [options1] <file1> [[options2] <file2> ...] [@optionsfile]
DESCRIPTION
This program takes the input from several media files and joins their streams (all of them or just a selection) into a Matroska file."

I want to convert an MKV file to BD5, in order to burn it on a DVDRW to test the BD player capabilities. So far I know, no BD player can do MKV. Maybe PS3, but PS3 is not a BD player :).

But you missed the title ;)

Nevertheless, I do not watch movies or hear music on computers - I think this is pathetic, therefore DivX and its relatives, or MP3 and its relatives, are unnecessary complications in a world already complicated by various standards that require antagonic conditions.

I think more than 98% of all questions in various A/V fora are practically linked to Divx and mp3 conversions, their incompatible codecs, or similar - "surface" aspects that let less time to reach the real core.

There is one: LG 370 European version.
