Hi Zathor,

I've found a way to reproduce the Audio bug that i mentioned earlier.

Here are the steps

1. Download THIS 2 channel AC3 that i borrowed from MASH

2. Create 2 copies of the downloaded AC3, call one TEST1.ac3 and the other TEST2.ac3.

3. Make sure there is a worker 1 and worker 2 setup.

4. Change the Nero AAC scratchpad to this, press update and close.



5. Load TEST1.ac3 in to the audio track 1 in MeGUI and click enqueue.

6. Load TEST2.ac3 in to the audio track 1 in MeGUI and click enqueue.

7. Click on Queue tab and click start.

run these jobs multiple times and inspect the output sizes of the mp4s created,
Code:
Run 1:
TEST1.mp4 = 1.63MB, TEST2.mp4 = 1.12MB.
Run 2:
TEST1.mp4 = 1.64MB, TEST2.mp4 = 100KB.
Run 3:
TEST1.mp4 = 100KB, TEST2.mp4 = 1.19MB.
Run 4:
TEST1.mp4 = 1.63MB, TEST2.mp4 = 1.13MB.
And the LOG

EDIT: OK found the problem, it's normalize() in the AVISynth script. If you disable normalize peaks to ... in the nero AAC encoding config dialog the output files are the exact same size.

Code:
without normalize enabled.
TEST1.mp4 = 1.51MB, TEST2.mp4 = 1.51MB.
