Hi, Iīva here a film with a delay of +80ms.
Now I used the AC3 dely-fix and thatīs what the proggie told me:

Sampling rate: 48 kHz
Nominal bit rate: 448 kbps
Framelength: 0x0700
Length: 173407frames (01:30:18,969)
80ms to be add.

Target file information:

3 frames (94ms) have been added.
173410 frames (01:30:19,062) have been written.
There are 32 frames in one second.

My Question(s):
Now I have a delay of -14 ms, isnīt this right?
Is this a program error or what? If yes, is there another program out there that will do the correct delay...
Can a human realize this little delay?
Other thing:If I author with e.g. Spruceup, will this problem be automatically corrected?
Thx a lot,mcp.

YES

How should the program add fragments of frames ?
If you want it exact, use Maestro and do a manual align. How, I've postet that here twice.

You're kidding ? NO.

NO
