Hallo I use AutoGK 2.33 beta with lame 3.97 stable added and the main-EXE from 2.27 for .mono-encoding, which is missing in hidden options since. One fails to make AutoGK accept ".mono"

i want to use commandline settings for lame (and azid for manual dynamic-range-compression - "heavy"):
--preset medium -mm for mono encoding - also standard and extreme

can a commandline input-field be implemented in future?

if not, do i have to:
1. demux and encode sound seperately
- how can i demux correctly with DGIndex.exe? Just "Audio -> Output Method -> Decode AC3 to WAV" ??
2. encode film without sound
azid, normalize, lame
3. mux together
VirtualDub: Streams -> Stream List -> Add -> [contextmenu] Interleaving...
- how should i manually set the delay (+ or -) in VirtualDub in the "Audio/Video Interleave Options" ??
There are three fields (preload, delay, skew) and two checkboxes.
from .../AutoGK/DGMPGDec/DGIndexManual.html#OutputMethod:
"...In the example above, the audio delay correction is reported as -248 milliseconds. That means that the audio should be advanced by 248 milliseconds. The number -248 could thus be entered directly into VirtualDub's "Audio Skew Correction" edit box to achieve audio/video synchronization."
Nothing, that I can do wrong ?? So just as explained !?

And should i ignore or accept VirtualDubs "rewrite the header" from vbr to cbr alert (cbr/vbr offset) or should i combine the skew from the alert with the delay ??
in this forum i read "NO", not to rewrite the header
So AutoGK in process does also ignore the alert ??

Other way?:
Is it possible to pause the AutoGK process so that I can exchange the encoded Audio before calculating the VideoSize? The file is locked during AutoGK-processing. I cannot exchange it under windows.
Or to edit maybe one of the scripts inside the "agk_tmp" folder ??
Add "pause" or add the commandline for lame somewhere (didn't find the command) ??

Another way?:
Is it possible to compile an own "lame" and force mono or the preset of my choice, means compiling with own defaults and disabling command-line parsing?
Just an Idea, never tried. Need a Link for a "short" compiling-instruction.

Or some other possibility to develop AutoGK. (knowledge: started 20years ago: MC/Assembler under C64,delphi,PHP,JS,Tcl/Tk,C,etc.)

If you want to mux VBR Mp3 manually don't use Vdub. Use Vdubmod or Avi-Mux GUI.

Yes, I don't need a second VDub-Installation on HDD.
I always use:
AutoGK\VDubMod\VirtualDubMod.exe

Make sure "By default try processing MP3 VBR streams like Nandub" is checked. When opening a VBR MP3 you'll be asked if you want to keep the header. Choose "Yes", fill in your audio delay and you're all set.
There's no way to use custom command lines when encoding audio. I don't think len0x is about to add new features, so you might want to look into other applications such as MeGui.

Thank You.
Took a while but found the checkbox (long ago since i used it)
in VdubMod it's in
Options -> Preferences... -> AVI
Isn't actual, but I think for the Videos of my DigiCam it is nescessary to demux and encode audio seperately because AutoGK doesn't work with CCITT-uLaw.

MeGui? I have to check it out next WE.

Sad. It would be so easy to add this simple and always nescessary commandline feature...

Just wanted to convert Dinner4one.
Also no possibility to compress the whole film in greyscale. THe only possibility was to encode credits in greyscale from the 2nd frame on.

But if it's the intention of len0x to use AutoGK only with coloured DVD-Videos, then I have to decide do encode with GK, megui or something else...

O.K. these are the simple things I've been always missing in AutoGK.

Still searching the changelog for the reason why .mono-encoding isn't available since 2.27...

Greyscale is not meant for movies that are already B/W.

Mono encoding is still there. As the link I posted earlier explained, you need to select your IFO/VOB/AVI etc. and press Ctrl-f11 to enable advanced audio options.

I have a lot time to sit on the PC now because i'm ill now.
But i didn't know, that i'm blind! yes, mono-encoding, posted 2 times now:
crtl-f11.
a quick view in the about -> shortcuts: no entry
helpfile is also the old. changelog:
2.30 beta: ah, i should read the whole line...

Greyscale: dinner4one: the original is bad mastered 4-6 Mbit Material (and more blue then black & white) and with coloured artefacts which weren't so ugly after encoding with greyscale.
Because it doesn't save so much space (280MB with 75%) i will burn it to a miniDVD (just 11 Minutes - 400 MB)
