90° rotation is not mandatory with M6

like many I guess, I forgot the 90° rotation and thus incidently found it was not mandatory !

that means the M6 does play 320*240 movies too ; I only made some very fast check on one sample , and at a glance it looks it will only do this with rather low cpu load movies ( say under 300k )

very short samples but the M6 play both entire clips okay

Yeah, we know this, but if you rotate the video with 90° the M6 can process the video better and thus it will look much nicer! Non-rotated movies look worse.

non-rotated videos will stutter heavily in fullscreen high action scenes. There is just no reason to not rotate.

it's like saying walking forwards is not necessary. you can walk backwards or sideways too! sure you can get where you want to go, but it's not the best way...

:D Nice example!

Auto-rotation is already automatically fixed with my converter. Don't even need to think about it.

the M6 always stutter anyway ! simply put side by side a M6 and a Nano on what you call "fullscreen high action scenes" and it is *so* obvious ; even on yet low conservative bit rate the M6 does show its lack of power

other point , if you look closely/carefully , the M6 even simply does not achieve a perfect sound sync

and I am not talking of stratospheric bit rate ; so...

and BTW where did I engage anyone 'not to rotate' !?

on the contrary , another M6 drawback is the need ...to rotate the screen :D ; perfect in axis viewing does not achieve the expected best screen rendering ! you have to tilt it a bit off axis ; but careful...5° more apart and the screen is fully messed (dark/bright balance)

the M6 remains a very nice audio piece of gear though

watch this, then we can talk again.

yes this sample has correct sound sync ; indeed if the M6 would always stutter or always be out of sync, it would not have gained its overall good reputation

but there are many occasions where it does stutter , or outsync ; and this not because you worked out a small "demo" OK sample that it proves this is wrong

now, incidently, I just looked inside this very auto-highly praised "video encoding final solution" and found it is a bit...obsolete ! please note , the M6 decodes up to Level 3

while this encode sticks to Level1 !

0x0008AEA6 Visual Object Sequence
profile_and_level_indication = 0x1 (Simple Profile/Level 1)

which may explain for the (relatively) deceptive image quality *given the hight bit rate used * ; cleaner , crisper image should be expected from average 400k ; it is possibly due to using Level1 ...

especially since it is no high action sequence ; mostly static

now unfortunately there is little one can do with Mpeg4 Simple profile , so I will sure not blame you for this ; the M6 has to deal with this limit , hoping the M7/M8 will support H264 at the better level/profiles

have a look if you can upgrade this 'optimal solution' to Level3 and it may prove to be better ; don't get me wrong , it is yet quite ok overall , but a 'dedicated compressionist' will always look after more and better

this is reproducable with any video of your choice. And yeah, it proves you're wrong.

wrong again, I don't use MPEG-4 profiles at all (yet). Whatever you found there might be a default tag, and nobody else but you seems to care ...

Hm, uh. What was it again, you have achieved to improve our videos ?
This is the best I have seen so far, and I'm personally very happy with it. Watching videos on my M6 is more fun than ever.

>I don't use MPEG-4 profiles at all

1) ho yes you do ! :D now this simply proves you haven't the slicest idea of what Mpeg4 Levels and *Profiles* are ; sorry, plus go Google ...

2) and sorry again, I am not that impressed at all by this sample ; it's just simply what Mpeg4 Simple Profile (even @Level1) will produce for such a bit rate

> This is the best I have seen so far

well....again just basically too normal quality for the bit rate ! really nothing 'special' !? and even imho some waste of bits for the final result ; Level3 and lower target bit rate would probably prove more efficient ; with here 280/300k a better (sufficient/equivalent) sweet spot

> and I'm personally very happy with it.

which is the more important, finally ; happy for your ego

Still, I am sorry to disapoint you but there is no 'guru' which can overcome the inner limitations of Mpeg4 SP ; Batman remains a simple front end !

>What was it again, you have achieved to improve our videos

and as for encoding videos for the M6 , I surely stick to VDub , a vastly superior video software ; nobody made anything better yet.

end of transmission.

You better stop here before you lose the rest of your dignity ..

Apart from that it takes even an advanced user a couple of minutes in VDub to do the cropping and resizing for each individual video and lots of video types are simply not supported by VDub (many beginners are simply overcharged by VDub*) - where is your superior demo ?

*which is doubtlessly a great piece of software that I use everyday Just not for Meizu conversion.

don't make a fool of yourself , pliiiiz

you have a tremendous ego problem , and it's always the case with so called self intronised encoding 'gurus' ....

>where is your superior demo ?

you hardly understand anything , my God ! :D I keep saying there is no such possibility !! but since YOU have found the secret of hidden miracles in Mpeg4 SP , then go here :

http://www.meizume.com/45822-post12.html

dl the source movie and give the amazed audience your so superior encoding martingale demo , joker ! just like you claim in your batman demo movie subs "finally the real thing , etc.."

ha...please try not to cheat with crop ( keep the original source resolution) , please try not to cheat with some processing on the image, please try not to cheat on bit rate/file size ( 300kbits) , etc..

do your best and let's see -your- 'superior demo' :D

see ya

let me summarize :
- you insult me
- you gave us no piece of software, no instructions for virtualdub, no nothing
- you don't have a demo video
- you're unobjective and make things up ("cheating", "intronising", "guru", "secret of hidden miracles")

My time is too precious to waste anymore of it on you. This is the last reply you will get from me.

what a hell does this thread come to "demo video" !? but OK you came with a video file and such claim as :

-" This is the best I have seen so far,"
-"this is reproducable with any video of your choice"

in short that this Batman 2008 super encoder would cure anything from M6 short cpu power to ..asthma ! possibly ...

now as this is some follow up of a former thread where I already demonstrated that such esoteric claims on Batman extra quality was nonsense , then okay I simply challenged you with demonstrating this 'end of the journey' (sic) new Batman 2008 version etc.. would make anything better

again here is the movie source , here is an ('my') humble plain vanilla basic Mpeg4 @level3 no fancy encode** , which simply produces the very same result as such esoteric Batman's "Experimental QX Profile"

(** you have to take this file for my 'demo video' ! sorry I still call this 'basic default encode' anyone can do )

and from your two claims above , sure I expect this 2008 version can at last now outperform any default VDbub encode ! so common it's your big moment ...or time to admit all this is nonsense

again here is the source , keep the resolution , keep the bit rate/file size, and show that "it is the best so far" one can get ...

http://www.meizume.com/45822-post12.html

if you can fulfill your claims , it will be profitable to us and deserve kudos ; otherwise we still have Vdub and default encode setting to achieve ...the same "best so far"

a fast look inside the movie with unbiased tools (..) confirms what I would think ...



a lot of wasted bits here (imho) ; just for the record ? I dunno ; since it is no super hard sequence to encode, on the contrary it looks the more often like 'talking head' video , in a sense that it is mainly a collection of rather static large close ups on actors .

the largest bit rate peak is associated with a very moderate action sequence ; otherwise bitrate peaks are mostly simply associated with scene changes ;

so mostly "wasted bits", why ? well at time 49 , for instance, since the scene is quite static with a close up on the actor , the bit rate -should- go much under 400kbits ; especially given the image is not so clean overall , always just a bit fuzzy; I mean much sharper image can routinely be obtained when encoding for the M6

indeed this has to do with the movie ; here the rather low gamma , nearly chroma decimated aspect , does not help for super bright, sharp , 'flashy' image ; so it is not ( a critic) only related to the encoding but a simple consequence of the image aspect

an interesting point to note is that brave little M6 does fulfill its 512kbits 'target max bit rate' rather nicely with such type of little/slow motion video ; indeed on really fast action movies with lots of front scene details and back scene stuff , etc.. to encode , it would simply collapse under too long , too sustained bit rate peaks periods duration ; here as they are very short , the M6 still copes with that

as for the codec itself , such kind of video , with mostly one character in the screen, not many details and static too as they are , is definitely not a big challenge . So , and sorry again, it does not show anything new with XviD in 2008 ; all is known and has been said about Mpeg4 part2 in its Simple Profile

it is weird that the upper Level 3 accepted by the M6 is even not used here , since the encode sticks to the more basic SP @Level1 !?

now there would probably not be such difference but I have no will to check this ! we speak of very old DivX4 like video type , a kind even before XviD was born...

time is now for H264 and M7/M8 when... it will dare comes to us :/

PS : since you ask for what Vdub and XviD can produce for nearly half the bit rate you use, well here is a sample where average video is @258kbits ; many will probably think it is quite ok while deceptively not "experimental Qzx002 insane secret preset " ; basic default codec settings ...sorry !
