Multiplexing takes long time

[semi]

Just wondering why the multiplexing part takes so long time...in Tmpgenc it's done in a minute?

Producing a MPEG-2 program stream of 775MB TMPGEnc mpeg tools simple multiplexer took 4 mins 57 seconds

same test using SVCD2DVD's multiplexor - mplex 4 mins 42 secs.

Both test done on:

Operating System: WinXP SP1 
CPU Speed: P4 2.8 GHz 
Harddrive space: 120 GB ATA 100 
RAM Memory: 512 MB PC1066 
Video Card: 128 MB DDR ATI Radeon 9700 Pro

HD fully defraged.

Have you got a super optimised version of TMPGEnc?

Seems like it. A 163 MB mpeg 2 took 32s to complete in tmpgenc (normal multiplexing, not simple) and from svcd2dvd says "multiplexing elementry streams" until starting creating vobs it takes 4min 48s !

So it takes little more than 2 hours to complete a dvd.


amd athlon 1.4 ghz

Anyone else?


(FYI: it also adds navigation packs to the resultant mpeg which tmpgenc doesn't. But i would not expect that to be significant)

well for me it takes over an hour about 1hour 20-30 mins... just depending if it is bins of mpegs....

but it has to demux, add nav points, reencode convert and reencode audio
and depending if its svcd2dvd or svcd2dvdmpg
it then remuxes the audio and video back together

one suggestion i have to speed this up is

give the option to use 2 or 3 hard drives....

use temp folders on them and all the demuxing would speed up if demuxed correctly to the different drives....

would hvae to think out the optimal way to do extract/demux for bin and also then mpgs only
or just extract bins then once mpegs start using the other hard drives....

or i might be faster to extract to one hard drive then move it back to same drive rather than extracting to same drive...

using 2 or more drives and them not being full and defragged would be the only speed increase.

I aggree. Multiple drive support is the way forward. I will add it to the list.

cool that will be nice to have!
