MKVtoolnix stretching and delaying vs. BeSweet transcoding

[bonanza]

Hi,

i've got following problem:

If I want to muxx an PAL (25fps) AC3 to a NTSC (23,976fps) x264-Video, I have to do a framerateconversion of the audiofiles and i often have to set a delay.

If I use MKVtoolnix to do this (I set delay:123 (or what ever I need) and stretchfactor: 25000/23976) and muxx the AC3 and the video...but then my video is not sync.

But if I set the same delay and stretchfactor in BeSweet and I reencode this and then muxx it with MKVtoolnix everything is fine. But this procedure is not very good because then I'm reencoding a lossy format again....

Now where is the mistake when Im using MKVtoolnix? What does it first? stretching or delaying the movie?

Hi 2 u 2

If I use MKVtoolnix to do this (I set delay:123 (or what ever I need) and stretchfactor: 25000/23976)

The "stretch factor", shouldn't it be '23976/25000' instead of '25000/23976'
