Problems with Framerateconversion PAL->NTSC, NTSC->PAL

[Pete The Chief]

I wanted to make PAL audio fit into an NTSC Video Source.
But when i activate PAl->NTSC i get only high frequency shit mp3s.
And when i chosse NTSC->Pal Besweet immediately crashes.

Are these still bugs? Or did i something wrong. (i habe the latest Besweet Build)

Sorry that i cant post the log file, i have it on another compu.

Looking forward for advices

Audio operates on Hz, not frames per second. So long as your NTSC-PAL converted video is the same length as the original source, you can use the original audio with no problem.

can you post your commandline ?

Hi.

There is one thing i don't undestand.

When converting an audio from NTSC (23.976 fps) to PAL (25 fps), the resulting audio shuld be shorter than the original, but when i convert a 1:56 minutes audio using the preset
"NTSC -> PAL (23.976 to 25.000)"
in BeSweet GUI (in command line is "-ota( -r 25000 23976 )") the result is a 2:01 minutes audio.

And when i convert the same audio (1:56 minutes) from PAL (25 fps) to NTSC (23.976) the resulting audio is shorter (1:51 minutes)

Well, a 25 fps movie is shorter than a 23.976 fps movie, isn't it?
The number of frames in the same movie, one played 25 fps and the other 23.976 fps, are the same?

What's wrong?:confused:

I have found the answer in this thread:

Go on with the good work DSPgupu.

btw, When will be ogg vorbis available in BeSplit?

PS: Take a look to your webpage, i think the server is down.
