DGIndex 1.0.12 Command Line Usage
How do I use the "Pre-Scale Decision" in the shell?
Either I'm too dumb to use the command line parameters properly, or it isn't implemented. I've read the FAQ and used the forum's search function, but I couldn't find anything helpful regarding this matter. |

Hi Donald,
is it on your development list? I'm doing a series (26 episodes) backup, and for each episode two audio tracks are decoded using prescale decision. So there are 4 passes needed for each episode. Each pass takes 2 minutes to finish. 2*4*26 = 208 minutes. Its annoyingly monotonous to push for over 3 hours every 2 minutes the same buttons again and again. If prescale decision were implemented for the cli, the pc could do the job without any further user input needed, after writing a batch file, which takes about 5 minutes. |

Process for each episode:
1) Open VOB file 2) Check options: Audio-Output Method: Decode to WAV, Audio-Dolby Digital Decode-Dynamic Range Control-Heavy, Audio-Digital Decode-Dolby Surround Mix Off 3) Choose audio track number 4) Choosing menu item Audio-Dolby Digital Decode-Prescale Decision starts decoding the audio track without any file output. After this pass in the Status Info there's a number (e.g. 5.51) for audio amplifying used by the second pass. After clicking the Play Preview requester the information window closes. The Audio-Dolby Digital Decode-Prescale Decision menu item is now checked (on). 5) After choosing menu File-Save Project the second pass is executed decoding the chosen audio track and writing the WAV audio file and the .d2v file. When finished, the Information-Status-Info field says 1.00. 6) Uncheck Audio-Dolby Digital Decode-Prescale Decision. 7) Choose another audio track. 8) repeat 4). 9) repeat 5). The Project file is overwritten. End of process. Last edited by mohn; 13th February 2005 at 18:40. |

Wouldn't it be simpler to just demux AC3 and run Azid on it to produce WAV file? (normalization can be done during azid step or after on WAV file itself via normalize?)

@ Donald:
> How would you see this working in the CLI? Another cli parameter, say -PD=1 (default: 0 no pre-scale decision). This should trigger for one specific audiotrack a two pass processing, which combines steps 1) to 5). And for each audio track one cli command call. For example: DGIndex -IF=[I:\test.vob] -IA=3 -FO=0 -YR=1 -TN=1 -OM=3 -DRC=3 -PD=1 -DSD=0 -DSA=0 -OF [F:\testa1] -Exit > I agree. We're planning to remove all that decoding stuff anyway. Oh no! Imagine, the author of one of your most highly estimated programs tells you that he will drop a feature, which is essential for you. I know of quite a few people, who use DGIndex the same way I do. To drop audio decoding at all is asking for program spin offs, IMHO. Last edited by mohn; 14th February 2005 at 23:15. |

@len0x
Why should the usage of two different programs be simpler than the usage of just one? Of course, I could demux and later use azid. But then the audio delay wouldn't be autocorrected, as it is done now for decoded WAV audio files. Sure, the audio delay is part of the generated AC-3 audio file names, but then you have to correct the audio delay manually in VirtualDub(Mod). DGIndex, the way it is now, is almost perfect for me as a GUI Tool. All I'm asking for is to use its DRC two pass auto gain feature from the cli. Last edited by mohn; 14th February 2005 at 22:43. |

I always thought, DGIndex doesn't touch the demuxed AC-3 files at all. The audio delay autocorrection for decoded WAV audio files has always been one my favorite features in DVD2AVI/DVD2AVIdg/DGIndex. Last edited by mohn; 15th February 2005 at 17:18. |

Besweet is a CLI application, so design a script that extracts delay from the file name and puts it as BeSweet parameter.

I still would have preferred an integrated prescale decision feature for DGIndex's cli usage, though. Looking at the GUI side, I still hope Donald doesn't drop the AC-3 audio decoding completely in future DGIndex versions. Last edited by mohn; 15th February 2005 at 18:12. |
