XviD Quality Settings. Yeah, the best quality that coud be obtained.

[CQ]

hei. i`m running a codecs test for a pc magazine (yeah, PC Magazine Ro) and i wanted to know wich are the best settings for this codec. Speed isn't important, quality... yes! So do youre best. gmc, 3 b frames, 2 pass encoding, adaptive... everyone, wich settings do you use and why.
bye. please answer!

ps. i know that is looks almost like the one posted in DivX's but... i'm in a big rush :)

[Didée]

On the main config page, press the button that's labeled "default".

All other parameters are only there for lowering the quality by a user-defineable amount.

[Teegedeck]

If you work for a computer magazine do something for your money and do what everyone else does: use the search-button! :devil:

Seriously, you do seem to have the right idea: use about anything that slows down the encoding process.;)
But don't touch those b-frame settings, I dare you! And I guess that's the main point Didée was hinting at, too. It would be a good idea to use one of the matrices that the gentleman who posted above has created, also...

I will let your violation of rule 12 ("Do not ask "what's best" because this question cannot be answered objectively. ") go unpunished because of your newbie-status. :D

[CQ]

you see, i get no money from this (one mag gives me 1o $ per page... imagine) so its more like bringing the infos to the people that cant afford doing this on the web. im like an charity organization. so give me a break with that man. the money i get are paying 10% from the phone bill. so... if you want to help me to bring the best magazine codec test to the poorest peole (almost :rolleyes: )... and dont judge me anymore. and using search... i know that are a few (maybe more) smart people out here that i must ask. and again, that nasty phone bill (im a student, so imagine handling that)...

[CQ]

ps. newbie... hihihihi man, just because i dont know (or i dindnt read) the rules it doesnt mean that i'm new to this forum (maybe i dindnt write any threads or i registred just in may). and the only thing that i asked these questions is that here are sticking the producers. so... (i know, to many so :) ) and believe me, i used these codecs before and i know a litle (maybe a litle more) but i wanted to be sure, to bring the highest quality information to my readers. bye and keep it real :)

[ChronoCross]

you Probably won't get a reply from anyone. Most People who research encoding won't give their secrets away. They will ALWAYS point you to the search button. Which is what might be best. I would recommend you do the tests yourself because there is no way you will be able to provide accurate coverage about the codec without seeing the results for yourself.....so your gonna have to do it anyway Follow the simple rules put forth by teenagedeck and Didee and you'll come out with fairly accurate results. if your looking to make an event more accurate story then your gonna need to research each function and what it does....through your own testing. Simply taking someone else's settings and trying to do a test with them will not work. too many combinations and styles to even come close to being a universal result. Good Luck with your story and that might be the most pathetic pay ever.....might wanna consider getting a new job.

[CQ]

pathetic pay... hihihi, its a pleasure man, If it was for that lowsy buks... but i like that. and since i'm a filo student (literature and other shits)... it its a hobby. i dont consider making something on this. I`ll be a director when i`ll finish the studies so... fuck (can i use this word?) those 10 buck per page!
and watch the thread...

bye and thanks for youre oppinion.

[malkion]

my opinion is it will take some time before CQ gets a quality codec comparison put together. considering it's still a for-profit venture, i wouldn't want to ever buy the magazine who puts together such amateurish and subjective articles.

You have got entirely the wrong impression. We don't keep any secrets about XviD, here; we rather advertise quite openly what we think is best. This is a forum for discussion and exchange of experiences for those who are seriously interested in video encoding.

Please keep it civil, folks.

CQ, I think you've been given good advice in that other thread and discussing them here further would be redundant. I'll see you there.

[CQ]

malkion, it ain't that hard putting all that together. It will be some kind of Sagittaire CoDec test with more accent on the visual quality. Amateurish... amateurish is when you do it all by yourself. But thats why Im kindly asking directly the developers of the codecs and everybody that's in this. It's a open test. Everybody can contribute with an ideea. So the result to be fair and nondiscriminatory (is it speled right? :) ). And I repeat: ITS NOT FOR PROFIT! I GET NO MONEY FROM THIS MAGAZINE! (another one gives me those lousy 10 bucks :) ).

Here is what i'm planning ---> http://forum.doom9.org/showthread.php?postid=544162

The devolopers will tell you to use the default settings, or use search.
Seriously, no matter what your opinion is,
This question has been asked to many times already.

Just because you are writting for a mag, doesn't give you special privileges, over others.

Use search.;)

[JuanCC]

Test yourself this settings and see the results .

There is so many documents that explain you , what is mpeg-4 and his features.

[JarrettH]

- 2-pass
- Q-Pel on
- Motion Search=6, VHQ1
- Changing the Aspect Ratio to suit the release...some DVD features are in 4:3 while the movie is in 16:9
- Chroma Motion on
- MAX I-Frame interval should be 10x your frame rate
- and Trellis on

but aside from those...everything else is subjective. All the default settings are best...IMO! Use a custom quantization matrix.
You'll pretty much find XviD looks a lot better then DivX and takes much much less time to encode.:)
I'm not a developer either, I learned a lot of what I know by searching these forums.

[ChronoCross]

Actually I am willing to help people out with some ideas on what's best per situation but I think asking for the best settings is rather pointless because it doesn't exist IMO. Anyone who says differently is kinda just diluting themselves.

Settings(DVD Backup)
Defaults Settings + Qpel and GMC + Didee's six of nine matrix or Fox Home Entertainment. never use Trellis with a custom matrix.

Those settings are for live action only. Since I do most of my encoding in anime I have a bunch of other settings I'm keeping to myself as I am not totally confident in their results(aka I haven't done enough testing). Additionally I'd like to point out that filters also play a pivotal role in encoding so you'll have to take that into account.

[Teegedeck]

I'm sorry, but I can't let this go uncommented: A 17-post-XviD-forum-user who first tries telling us that 'experts' (referring to himself, I believe) keep their settings to themselves?!? I didn't like that. And now that an old-timer (i.e. me) voices protest you are taking it back. But in a way like you didn't really mean what you wrote first. And the next thing I read, you are spreading that trellis shouldn't be used with custom matrices?!? Veto, veto, veto.

Please lurk a bit longer before you count yourself amongst the advanced users.

[yidaki]

I'd say it depends.

I mean, we're talking about perception here.
There's no 'best' way of seeing something.
Everyone sees a different movie.

It depends on who's watching, it depends on the source, it depends on everything from butterflies flapping their wings to your own mood :D

What's the best painting, what's the best playing orchestra, what's the best cloud in the sky.
There's no answer, only that it depends.

Ditto, imo Trellis is one of the most useful XviD feature -> next after B-VOP's and VHQ !!!

@ CQ

Regarding your test...

I can understand that you use H.263 for the low-bitrates, but why for high-bitrates ???

You said that your goal is the "best" visual quality, and not good PSNR/SSIM results...

Imo for high-bitrates you should use MPEG quantization (or a HQ dedicated CQM) !!!


Bye

[CQ]

try watching this

http://forum.doom9.org/showthread.php?postid=544162

you'll understand (i gues :D ) what kind the test i'm planning)
and here... thread closed. see you there!

[*.mp4 guy]

No trellis is the god of good features;)

Anyway listen to Teegedeck and soulhunter, they know what there talking about.

[ChronoCross]

I like how you totally discredited my opinion and made me seem like a total idiot. Don't appreciate that one bit.

It's not like I'm a n00b either. God. why does everyone look at the number of posts to determine experience.

[Audionut]

Originally posted by ChronoCross
and additionally I said the we keep the settings secret is because we do not share all our knowledge at once. We don't just give n00b's everything we have to offer do we? we tell them to search around and try things out and do it for themselves,

Perhaps you should speak for yourself.

edit: of course, if a newb comes here asking a question, that has been asked, and answered, plenty of times before, then he/she WILL be told to use search.

post your best settings. Then tell me I'm wrong. Or better yet just make a complete encoding guide that reveals all the tips and tricks you use. somehoe I don't think you will do that. Which is what I meant. We help out once in awhile but in no way do we hand over everything. Which is the point.

[Audionut]

Oh crap, flame war could arise.

If only I was the ALL KNOWLEDGEABLE AUDIONUT.
Perhaps then I could.
Pity, I only Audionut.

edit: If I was to post a stupid thing like you are suggesting, I would get bitch slapped by, Koepi, and others, instantly.

edit2: Most people are aware that you can not do what you are suggesting. There is simply no 1 set of settings that will work for all video clips.

As I said earlyer, speak for yourself.

Most people, don't come to this forum, and ask for the best settings for every possible situation.
They use search, then ask questions reguarding, specific needs for video conversion.

Best settings for what type of encode exactly?
DVD Backup?
TV Capture?
Lo Res?
Hi Res?
Low Bitrate?
High Bitrate?
Encode for best speed?
Encode for best quality?
Is the content anime?
Is smooth picture preffered over noisy, or vice versa?

This is just a small portion of the variables to be considered when encoding. There is NO SUCH THING AS THE BEST SETTINGS.

As a rule of thumb though, always use MOD 16 resolutions (resolutions where both the horizontal and vertical components are divisible by 16 without remainder). This WILL improve compressibility.
Motion Estimation 6
Use VHQ 4 - for best quality Use VHQ 1 for fast encode.

The rest is up to you to work out.

How many B frames? You chose, but it is suggested not to go over 2, but in some circumstances you can use 3 or 4.

All the so called "experts" are those that are patient to sit back and work out what everything does, and do tests with different settings for the material they want to encode. There are some good generic settings posted in guides for DVD backup, but the best settings really depend on whether the source is clean, whether you are using filters etc etc etc. What must also be pointed out is that what one person may consider to be an excellent encode, another may consider the same encode to be very average. I can obviously post the settings I use for encodes, but since most of my encodes are TV captures, they will not apply to DVD backup. I will also be flooded with PMs saying how much my settings suck, how using another matrix makes it sharper, how using one option increases PSNR etc etc etc.
IMHO video filtering via AviSynth makes the most difference in the final quality of the encode. The encoder settings are of lesser importance.

[ChronoCross]

well at least you got the point of my last reply.....the post your best settings was sarcasm...I know damn well there is no single set. and saying that you don't keep a few secrets to yourself is just obnoxious lying.

Most people, don't come to this forum, and ask for the best settings for every possible situation.

what can I say...have you actually been reading the forums? at least 60% of the topics on this forum have started containing the word Best or greatest.....

[ChronoCross]

and you know what since I'm beyond this now I'm closing myself out of this thread. no more replies. sorry mods if I was a bother.

[Peter Cheat]

I keep no secrets about encoding, and I doubt others do. I get nothing by keeping secrets about settings I use to encode material. If I was personally asked about what settings/scripts I used, I would happily post them. I keep most of the scripts that I have used since I started encoding. Why???. As reference because each time is different with different variations of different settings and different filters using different parameters.

I see witholding any information as being detrimental to society in one way or another. I always share what I know or my opinion on a subject when asked, or when I feel it is necessary. Some may say that they have some "super settings that are absolutely awesome" but my experience shows that they are just trying to get some sort of attention and a (false) sense of power. Everyone that has anything useful to share almost always does share it.

I'm out

[dragongodz]

saying that you don't keep a few secrets to yourself is just obnoxious lying.
maybe i missed those secret settings in xvid. or maybe i am not an insultive wannabe ? :)

I know damn well there is no single set
then why do you keep pushing for people to post their settings ? Peter already listed a bunch of variables that can change what settings may appear better TO YOU. people do have different opinions of what they like quality wise of course. so telling someone to try different settings and see what they prefer will always be the reccomended way.

have you actually been reading the forums? at least 60% of the topics on this forum have started containing the word Best or greatest..and have you read the forum rules where it states not to ask whats best ? or how about in those posts where that rule is repeated ?

truly a thread going nowhere fast. :D

[ChronoCross]

bah just because some people aparently can't read sarcasm.....I was doing it to prove a point. no one will give awy their best settings for anything. They always tell people to try thing son their own....which was the point of me telling people to give their settings -_- guess I should be less subtle next time.

[dragongodz]

no one will give awy their best settings for anything. They always tell people to try thing son their own
its you who have missed the point. IF you ask about specifics such as "i am doing an anime to this resolution at this bitrate and am wondering if anyone else sees any advantage in using more or less B frames" then you would no doubt get peoples opinions and their experiences. you would still be told to try for yourself though. why ? because no 2 peroples opinions(especially on quality) is exactly the same and never will be. quality or the type output is something you must decide for yourself, always. a generic "whats best" does not exist which is why its against the rules. either you understand that or you dont.

bah just because some people aparently can't read sarcasm
actually you cant "read" sarcasm because it has a lot to do with the tone something is said. i have also used it on this very forum and sometimes people recognise it the way i meant and other times they dont. try to say what you really mean more often and there wouldnt be any confusion. :sly:

[Teegedeck]

Oh my; a few hours away from the forum and how has this thread evolved into the wrong direction! I'm sorry that my own post fuelled this development.

Let me clear this up: My initial intention was to give ChronoChross a friendly slap on the fingers because he was lacking modesty, advertising conduct (secrecy) not in tune with the spirit of this board and giving false (or at least very dubious) information - a very unlucky combination. ChronoChross felt personally attacked and hit back. Not the reaction I had hoped for, but a common reaction. I should have foreseen this and expressed myself more cautiosly. For this I apologize.

I will wrap this up, explain my point once more, and as a moderator I will not tolerate this getting any more personal or off-topic. I will split the trellis-discussion into a new thread where you can continue this discussion if you like.

Alright. ChronoChross, you have joined this board on June 1st, 3 months and 13 days ago; your post-count is 24. You are a newbie by any definition and you'll have to live with the circumstances that come with this status as long as it lasts. As we all have. You will have to adapt to the rules and it would also seem good to adapt to customs of this board. We all have.

And you will have to get over this 'We help out once in awhile but in no way do we hand over everything. Which is the point.'-idea. If this sentence is true for you, this is sad. But don't project this onto others. We are not like that. I will gladly give away anything I've learned and hope people will put it to good use. Convincing people that XviD is very fine codec is one of my motivational factors here.

'The number of posts on this board has no direct relation to the experience of a member.' is part of rule 11 and you see your behavior rectified by this sentence. But rule 11 has a first line, and this first line reads, "Don't post just to increase your number of posts. If you have nothing to say on a certain matter then don't post. " The rule was set up because some people did just that; they posted nonsense in order to increase their status. The rule can be read as 'you can have a post-count of 1000 and still be an idiot!'. (Others have surpassed my number of posts within just a year while I've been here since the first alphas of Nandub.) Of course we encounter very respectable newbies from time to time. We recognize them by the quality of their posts or by the sheer dignity and conduct reflected in them. Sometimes real pros and reknown programmers join the forum.

But in general the newbie status is something to be taken seriously. It is a time to make your name here, you don't get any natural recognition just because you are you. I also remind you of our rule 2), 'Respect the netiquette: Lurk and get to know the forum before you post'.

ChronoChross, I did certainly not want to hurt either your feelings or your reputation on this board; I apologize for that. If there is anything else you want to tell me in this thread, please do it now. The thread will be closed/split shortly.
