MNCSamplePreview - A new tool.
Updated 12/JUN/2004: Added "preview only one chunk" (from a desired beginning time, during a given time.)
Updated 08/JUN/2004: Efficiency improved. Added chunk time selection. Added reset and new sample encode. Updated 07/JUN/2004: Fixed bad order of chunks when rebuilding m2v final stream. ---------------- Hi: Do you ever ask yourself for a Sample Preview for Mencoder. Here it is: MNCSamplePreview.bat Explanation: MNCSamplePreview.bat works taking samples (usually as many as movie time in minutes) of 1 second each one. In MNCSamplePreview.bat, you can select number of samples, but not time of samples (maybe in a future, it is not hard to do). The final stream only can be played for MPlayer. Other players don't play it fine. Maybe one of you, friends, can tell me how can make it play with other software. (maybe it will fix with an option). It was tested for a preview of movie with settings in temp.conf, but not for prediction purposes. MNCSamplePreview.bat will play the final stream. Downloads: Download Latest CVS Snapshot Mencoder Builds. Download MencodeMe - GUI for Mencoder.exe plus Mencoder.exe, MPlayer.exe and libraries. Download MNCSamplePreview.bat only if you want to see the source and improve it. Tool Install: 1 - You need Mencoder.exe. 2 - You need Mplayer.exe. 3 - You must to have all libraries (CygWin1.dll) needed for those programs. 4 - You can use MencodeMe or PackShot for making temp.conf file. Also you can make that file from scratch. 5 - It is better that folder with movies would be one folder into Mencoder.exe folder, but you can keep your movie where you want. 6 - All programs, Mencoder.exe, MPlayer.exe, Libraries, MNCSamplePreview.bat and Counter.txt must be in same folder. Counter.txt is a file needed to get 3 digits numbers that are actting as counter. 7 - Spaces into folder or movie names are prohibited. Tool Usage: 1- Generate your temp.conf file in working folder. Wth MencodeMe, PackShot or handly. Its name must be temp.conf. Encode.bat file is not necessary, MNCSamplePreview.bat will generate a standard (like MencodeMe), 2 pass encode.bat. 2 - Run MNCSamplePreview.bat. 3 - Input movie folder path (path without spaces). If your movie is in a folder into the working directory, it is enough write the folder name. Supose you have a Samples folder inside MencodeMe working folder, in this window you can write Samples. If your movie is in another folder you must to write full path to it. (i.e. C:\Movies\MyMovie.vob) 4 - Input movie name with extension (Movie.avi, Movie.vob, name without spaces). 5 - Input number of samples (usually movie time in minutes). 6 - Input vbitrate value (avg bitrate). MencodeMe or Calcumatic can give you it. 7 - Select between encode sample, single preview, looping preview and exit. Hints: MNCSamplePreview.bat work in a command prompt window. You can change aspect of that window just left clicking in upper left corner of cmd window. In options tab mark "quick edition modality" and "Insertion modality". With the first one, you can paste any text in cmd window just right clicking. It is very usefull when you want to paste a full path or a movie name. Second one will permit you write some text without overwrite previous text. In others tabs you can play with fonts, window place, background color, text color etc. Code:

Hi Pro, There's got to be some problem here. I tried to download the MNCSampler.bat and my Anti-virus tool advised me that I was downloading a program with a Trojan Horse named Digarix.B. I'm sure there's some problem with either your provider or your PC. Can you check that please? Cheers :!: Attention :!: |

For sure it is not a virus. Sampler.exe is batch file compiled. I am' strongly antivirus protected. I do a full scan every week (last yesterday). Not virus reported. I donīt understand. What file reported virus. Bat or exe. Don't worry, I am posting batch file just now. -------------------------- Visit: Intermediate guide: MencodeMe/Win32 - Avisynth - MakeAvis by Prodater64.

I was starting to download the whole package when it happened. But I started with the batch file MNCSampler.bat. I tried downloading it twice and it always reported me the presence of a Trojan. As this happened with this file I felt that for safety I wouldn't try to download the MNCSampler.exe. Sorry for this buddy but it's just that lately I have seem many Trojans opening the door for hackers attacking. Most of my customers have had such problems you know... What about submiting the batch file again to your webspace and I'll try to download it again too? Cheers EDIT: Forget what I just said. I just downloaded the sampler.bat and now it doesn't report any Trojans. But I cannot say the same about the *.exe one. I tried the sampler.exe and now it's reporting the same Trojan that it was reporting on the batch file. |
Don't download the exe file for now. I'll check it.

It is fixed now. Later I will check what it is happend.

Thanks for this Sampler Pro I like the idea of this.
Great work im going to do some tests also. :) EDIT: Scanned the bat file with AVG Free version and it reported no Trojan or Virus and my AV is fully updated. Just thought id let you know Pro. :) |

In other words : with an encoder that CAN'T GIVE any good result in 1pass ? I think you all miss something in the mencoder theory gentlemen... |
And in that "sampler" a 2pass is used? Do I see that right Prodator?
Do some people still got inacurate avg bitrate results in ther encodings when using 2pass? I never had, ... so I maybe missed something. On the other hand I underline the statement of Phil, as it has been proofed that 1pass does result in finally more "avg rate matching" results then in constant quailty. Thats how mencoder works with our actual settings. I remember when Phil encoded one stream just using 1pass where the beginning till the middle resulted excellent and the end finally ended up alful. I also did some tests on 1pass/2pass and 2pass does allocate the bitrate much more precisely therefore 1pass in mencoder when using our actual parameters is not quality based like CQ in Tmpgenc. |
Quote:
BTW this unacurracy if mainly due to underflow problems (each time you have one, the avg bitrate that is reported on the line just bump to a radndom value !). As these underflows arrive at different moment according to bitrate, I guess this make any prediction impossible : you can have a encode with bitrate=1500 and no underflow that will be too big and the same a 1600 that will be too low because of lots of underflows. Really Pro (and otehrs) you should consider to stop doing such long post and ask a little for some advices. I don't want to be rude but it's clear that a lot of people here do not handle completly the problems we are dealing with but this don't prevent them to do GUIDES :!: And that is not a mencoder only remark ! |

Sampler is for previewing, a global view of whole movie. It don't has prediction wishes. Mencoder don't need prediction. Other thing. Maybe you can give me another lesson please, I think that Mencoder yes has quality encode mode, you can keep Q in a value and Q won't move of gived value. I know that we don't use this way, but it is possible, or not? MNCSampler, give you a preview with 2 pass, this is an explanation in case that you don't had see that in the script. It has an error in order of chunks, as told me rds_correia by PM, and I will work over that. -------------------------- Visit: Intermediate guide: MencodeMe/Win32 - Avisynth - MakeAvis by Prodater64.

Prodator I like your work and so these kinds of works generall do have my respect ;-) but we also he to see things in their quintessence,
In here we are used to see a "sampler" in combination with an encoder to see as a prediction tool. And no matter what you write in your instructions, .... many people will see it like explained in the line above. Thats why some pals could be confused. Thers NO criticism on Zyphoon at all, Phil just tried to make clear the situation thats all. Quote:
As we dont encode at "flat" Q but using a dynamical Q which bases on motion estimation algorythm, that Q curve is at mencoder at one pass NOT accurate to a bahaviour it should be. If you tweak your Q curve to more flat in mencoder, then your approach could work, but in mencoder a flat Q does end up in bad results in lower bitrate scenes and EVEN forces then bitrate drops. Well you could force a Q of 1 but the mega end size would be the result. |
Quote:
You ask for my opinion but I gave you my opinion while I was answering to Zyphon : a 'prediction tool' for mencoder is useless and I understood that you batch was such a tool. But I don't really see the purpose of a preview file either as the result of an encoding depends on the bitrate repartition all other the movie and you can't just "cut a slice" and encode it even in two passes and hope the result will be the one you wil have in the real encode :!: :arrow: again MENCODER IS NOT A QUALITY BASED ENCODER ! So you can't work on a sample and extrapolate the result on all the movie like you do with tmpgenc and CQ mode ! So I'm really sorry to have commented badly your tool without having effectively read the script but the final comment is still the same : useless and lack of time; I'm sorry Pro. |

Phil, I did write a MEncoder guide but I wasn't aiming to explain MEncoder in detail on it. Just the basics. Such guide was just for people to "get into" MEncoder and by the use of AviSynth scripts. That's what I was aiming. Fortunately soon we had more buddies like you visiting the FFmpeg forum and that really have been helping me a lot. Besides that I come here everyday in search for more information that you and others can provide me so that I can improve my skills. Which by the way are below the average skills here and I never tried to hide that from anybody. Once in a while I try to aid somebody as some of you do with me when I'm needing help. And when I see that I cannot help I try to prepare things so that one of you see the guy's posts there is already enough info to deal with it. That's basically it. I was just trying to help buddy ;-) Cheers |

(as you probably understand there, I'm a little more upset by other things that the one concerning mencoder ;-)) And the pervert effect of all of this is that we lose time to answer question from people that can't even understand the answer (and I do not blame them !) FYI 10 days ago I didn't want to go into mencoder because I knew how pathetic is the situation of this encoder. But I was litteraly projected in the roller-coster because of all the questions with no answer that I saw all around the forum. So this is your fault ! :-D :lol: |

First, I beg your perdon if in any form I confuse you all. Quote:

If script name to confuse you, I will change it, thank you for your advice. If any of you don't see this script usefull, don't use it. And finally come on with the firs one Quote:

I only ask something to rds_correia: Quote:
You read the word Guide here, in any place? What are you saying. If you talk about my guides, it don't speak nothing about technical issues. Those guides are for help people. They are an enough easy way for start with a DVD or an AVI and to arrive to a (S)KVCD/KDVD. They, my guides, I can't to speak for other people, takes parameters from MencodeMe, just the encode.bat and temp.conf files that MencodeMe do it, and people can modify them, but at his own risk. I donīt give advise over any option in Mencoder. But this, you don't know because you don't read my guides at all. (to long reasons) I know now what is true problem. Problem is that you think of yourself that you are to much, but you are nothing. Quote:

My guide, in his tittle, say very well that is an intermediate guide. Quote:

@Pro & Phil
Come on guys. I think it's time we post something usefull here. Too many posts OT as it seems this is a topic for those who want to try Prodater's batch file for preview. There are other ways of making conversation ;-) Cheers |
