MKVToolnix Windows 7 "The final Countdown"

[shae]

Any reason to use the x64 version?

Assuming it's just data shuffling, there's no heavy processing involved, and so no real gains expected.

Any reason not to? Should really be the default these days.

Sorry I can't resist to reply...

Two clashing philosophies here.

MKVToolnix does not do any REENCODING, it just REPACKS the cource for a different container. Which is very useful. But from many years of using MKVToolnix I do know that the speed difference between the 32bit version and the 64bit version is minimal to non-existent. On a PC with low system memory it can even happen that the 32bit version is faster.

So please stop the religious fight about 32bit against 64bit. In most cases the answer is "It depends".


Just my 2 cents...

I thought it was you who just tried to religiously defend 32bit?

64 bit software decoding is massively faster. what was it 2x for h265 and 15 % for h264.
yes 64 bit software usual addresses more memory compared to the 32 bit version but that's it.

32-bit is potentially more compatible, and potentially smaller.

[manolito]

Correct...

Since MKVToolnix does not do any reencoding of the source files, there is no real acceleration when using the 64bit version. When using the GUI version MKVMergeGUI the GUI could potentially run a little faster in 64bit, but in my tests I did not get any speed increase with the 64bit version. Probably because the GUI uses the (64bit) operating system for all the mem copy and screen writing operations, so even under 32bit MKVToolnix these operations will run in 64bit.

And if you have an older computer with low system memory and a single-threaded CPU then the 32bit version will almost certainly run faster than the 64bit version.

it does compression. and compression algorithm also benefit from 64 bit. you are usually limited by the IO speed anyway.

yes a single thread CPU with not enough memory to run the OS will benefit from a 32 bit version.
or you just get a dongle and use your smartphone instead.

the argument is pretty much the same as 32 bit version run on a 32 bit os the 64 bit doesn't.

AFAIK it uses lossless compression only for subs by default. Video and Audio stays as it is. Quote from an older post by Mosu:

And all this applies only to the final remuxing, the source tracks are never decoded and then reencoded.

yes i said compression but fair to point out.
very useful for LPCM too.
