To enable a menu, you may want to take a look at step 13 of one of my guides: http://adubvideo.net/how-to/convert-bluray-dvd-avstodvd
It was originally written to support Blu-ray conversions, but the menu process will be generally the same. |

can you add in the proper avisynth script to ensure HD colorimitry is converted to SD colorimitry properly?
would would need ColorMatrix and use: Quote:

1. Do all mpeg2 HD sources have the "wrong" colorimetry? 2. If not, how can it be detected? 3. Reading from ColorMatrix description: Quote:
4. Why are you suggesting to add (by default) a sharpen filter when downscaling? From my experience, sharpening is good when upscaling (lanczos does that trick very well). BTW thanks for the inputs: posts like this are the best way to help AVStoDVD to grow. Bye |

I have been making SD from my HD stuff for a while and have found that a sharpen after downsizing looks good...but again can be made a radio option.
as for a colorimity is concerned, a number of people (manono???) have stated that you need to convert it properly from HD to SD. Also: http://avisynth.org/mediawiki/Colorimetry Quote:

also...what about permitting user to set max bitrate? Always greyed out. It is true that you can edit command line parameters before you run (tick box), but that also opens up the parameters for muxman...maybe two options here as well; one for editing hc and one for muxman as well as in gui for max bitrate.

Mmmh, before implementing new feats, I would like to fully explore the rationale behind them. Adding new feats is great, but only if they are really useful and they do not create confusion in users mind (first of all, mine...).
Thus, Ron, please, if you have time, help me to find answers to questions 1-2-3. About MSharpen, since it could be useful to improve anime encoding too, I will add it to my ToDo list. About max bitrate: see reg key Quote:

Hey...thanks!!!
remember my comments are for converting HD to SD, which your proggy does very well...much better than the manual ways I have been doing. so: Quote:

As far as question 3, I never use Qenc so not sure, but really, who cares what the encoders assume or flag (if they do at all). Specify it explicity in AVISynth to take care of the issue. Is this not better anyway? So if you want to expand you program to include HD to SD conversion, then, in my humble opinion as I am not a programmer, is to have two extra buttons for colormatrix and msharpen. As I said before, I have been using this method for ages now and the output is fantastic, quite often BETTER than the commercial DVD of the same movie. As far as max bitrate, why not make it an option to change as opposed to a reg entry? Cheers, and thanks for the consideration. Last edited by ron spencer; 7th April 2010 at 01:47. |

Ok ron, you have persuaded me.
Please confirm following statements: 1. It seems that only DGIndex and GSpot can read the mpeg2 colorimetry standard 2. DGIndex names "BT.601" as "BT.470-2" 3. Colorimetry flag is not always specified (DGIndex puts a *), so it is pratically impossibile to always detect in advance the colorimetry itself Thus no auto ColorMatrix, just an option button in the AviSynth Tab (as you suggested) to change colorspaces. On a side note, MediaInfo has a "colorimetry" parameter, but unfortunately it is actually Chroma Subsampling (i.e. 4:2:0) and not ITU-R Recommendation. Bye |

You will need to verify with neuron2 your dgindex comments, but I believe they are correct...maybe PM him.
You are right there is no way to test for sure what colorimitry is, but I assume all HD sources follow "the rules". In any case I always do this for my HD to SD conversions and my anecdotal evidence, at least on my 50" Samsung plasma, is very compelling. Remeber, this is an add-on feature to your great program...probably best just to have two checks/buttons to add this. Then it is up to the user to change. Thanks again for the consideration of this feature...again I am not a programmer so I can only complain LOL!!!! |

I also notice that when you give a DVD label a name, there is a number attached to it (folder name).
For example, if I label (first page of your GUI) the DVD "Test", it will make a folder called "Test_0" Why is this? Can we make it just "Test" |

AVStoBlu-Ray
First, thanks for the great software, it's my favorite when converting to dvd.
But I want to upgrade to Blu-Ray, and it would be nice if you could make an AVStoBlu-Ray program, that could generate mpg2 streams comtabible with Tmpgenc Authoring Works and h264 streams compatible with multiAVCHD. I don't know if HCenc cant create HD streams but it wold be nice to use the same procedures that avsTOdvd uses to create dvd, but for blu-ray mpeg2. |

Hi Don_Genaro,
first of all thanks for the kind words. About upgrading AVStoDVD to BD, I must admit that it is an intriguing idea, but I fear that it will be impossible in the short-medium term. In these days (I have 2 little kids who are really time-consuming pearls) I'm already in trouble in supporting AVStoDVD and making some small development steps. BTW, AVStoDVD is an open source project: anybody can start from my code and expand it to support BD or anything else. Bye |

Hey MrC just wanted to say thanks for making this really great free software, i can finally move away from dvd2svcd . But there's just one thing missing for me CCE support, i really wish you would put this back in. For me its the fastest mpeg2 encoder and gives the best results.
Cheers M |

@Marvel
thanks for your good opinion. About CCE, support to it has been discontinued since release 1.2.0 (November 2007) because I have chosen to support only free software, and I have no plan to reintroduce it. Sorry. Bye |
