Motion Blur > Not phisicali correqt. \Corona\vrayRT\Vray adv\Mental ray\ test

[3dstudio]

For Real life phisical camera 24 Fps shuter time is a 1.40 - 1.47,9 earlier I used Canon cam. to carry out tests and compared with a real camera motion blur with  mental ray and Vray.2  and get almost the same effect it the Sami as in real life, But look at this Picture and video  test. Test soft >Boujou< for motion track and Max2012 vray/ mental ray. scanline. Premiere pro  fot comparison.
this is a test that I did now, the reason for this was a commercial project that looks bad in motion. had to find a reason, because for 10 years I add 1.4 Dur - for 24 Fps for different renders, Mental ray, Maxwell, Vray, RT, Scanline, Octane, Arion, By the way, I have not tested Thea renderer it what like when run the GPU preview max  is cut down.


Render settings is identically, all is identical, Do not look at noise level, look at Blure duration.



1,4 shuter open and cloce speed is not enoght for Corona render But 1,4 is a correqt for 24 Fps!!!
I think Need Fix it.

and forgot to mention this is A5 beta version

Do you animate camera, or the scene object?

[3dstudio]

animate only scene objeqt! BOX. This is a settings > CAMERA NOT PRESENT AT ALL this is a Perspective view render

[Ondra]

It looks to me that corona only lags behind, not that the duration is wrong - when going down, corona box starts higher, when going up, it starts lower.

BTW: what makes you say that duration 1.4 is the correct one?

[3dstudio]

corona is not leg behind, this is identical  rendering and animation!!!  here's the scene  and seeing render yourself. do not believe in my test make your!!!  my purpose is not to convince you or anyone that it is wrong not physically correct value, I tested it I see it and it s not correqt !!!


for me does not matter who that thinks. I did it for myself to achieve the right results what a fool would do badly for themselves!!!!!
do not believe in my test make your

[3dstudio]

BTW: what makes you say that duration 1.4 is the correct one? <<< if you have never dealt with a real camera and do not know Thet 24 frames delay aperture is 1.40 shooter speed....  there is such a search engine called Google sooo Google it. sorry for my bad English  I taught myself :P

[vkiuru]

Wow, you seem like an angry guy.

[3dstudio]

:D :D :D :D :D :D :D :D :D :D :D:  no it just seems I keep my nerves.... I just said that I do not care! who as it seems (by the way I really   do not care!  :)  The main thing that I reached my goal and made a correqt motion blur)

[romullus]

I can't imagine how 1.4 frames duration could be correct mb value. Typically movie makers use 180 shutter. It means that half of the time shutter is open and half of the time it's stay closed. So correct value in render settings should be 0,5 frames duration.
As for your comparison, maybe it's a matter of clamping? Do you use highlight compensation in post processing tab?

[3dstudio]

I can't imagine how 1.4 frames duration could be correct mb value <<<The defoult nomber is a 1,0 try Decrease this valve or increase and then you can imagine how can adjust motion blur.  sorry guys but first you need to know how it;is work (camera aperture)  and then imagine. those who know what I am talking understand and use in their renderers correct settings (or fix this Malfunction) happy render  guys.

[Ondra]

Ok, so

1) there is definitely difference between corona and other renderers, so I will investigate it regardless of you basically telling me to go fuck myself or not.
2) Here is another frame from your video, where the boxes go in the opposite direction:

Here the corona blur span is greater than other renderers. What have your and mine screenshot in common is that Corona result "lags" behind the others. Which may be a bug.
3) I dont know what "Frame" means for you. But for me it is the time interval between 2 film fields (images) in the animation. So motion blur with duration > 1 frame is not possible, because that would mean you would be sometimes exposing 2 frames at once.

[3dstudio]

you start to argue with me :D :D :D :D :D :D :D :D :D   Calm down!!!  so you can pick up and heart attack. :D :D :D  I forgot to say the Fuckin magic word what a cool render Corona renderer. (and it is true) it can relax you??? .... do not be lazy to download the test scene and mack your own Test. by the way ...that you came to my page?

Banned for 30 days. Hope you are just having a bad day and will stop with the hostile behavior after that.

[Ondra]

I've removed the last post, sorry to the author. There is no need to continue with personal thrashing

[Ondra]

ok, nevermind, this landed in my inbox after his ban, lets have som fun :D

[Ludvik Koutny]

:D :D :D

[Ondra]

Ok, I investigated the issue and there is no bug. Amount of blur is identical, the entire animation had an offset, because Corona has different range of frame offset parameter.

The claim about 1.4 frames being the right amount of motion blur is of course utter and complete bullshit. Standard value is 0.5 frames (http://en.wikipedia.org/wiki/Rotary_disc_shutter)

[Ondra]

BTW: The shit just keeps pouring in :D Now we are going into serious hacker territory :D

[jjaz82]

OMG :O really don't understand this reaction

[johan belmans]

gosh, some people really are ..........

Keep up the good work Keymaster!!

[Ondra]

Keep up the good work Keymaster!!

But I'm not even trolling him anymore and he continues going in full retard mode :D

[romullus]

OMG, Keymaster, you better start watching under your bed when you're going to sleep :]

[Ondra]

Show must go on. Imaginary friends included.

Mix of engrish and retarded flames. <3

He just needs to learn a serious lesson about friendship

[Utroll]

I'm already sad to imagine that the head of corona will be jailed abroad after being extraded by an international court :'(
Here lie the memory of KM's encounter with the producer-lawyer-hacker-tiger from internet's jungle.
Farewell sweet pony.

[Ondra]

Now my office phone is tapped, probably. Weird how all of his "friends" speak english exactly as bad as he ;). And how they use the same mail provider.


Cheers to gmail spam filter for marking the messages as spam btw ;)

[AdamHotovy]

I wonder if he understands Czech...cause he listens your czech phone calls...

[Ondra]

I wonder if he understands Czech...cause he listens your czech phone calls...

I'm not actually using that phone, it is shared in a big office. He just copied info he found on our research group page ;).

wow.
so hacker
much afraid

[Utroll]

" we will remind about us "
Ah, finally a good idea. Havalife.

You should be honored to be eventually the first dev. brought in a court by Xforce though ...
they probably patched the Law :D

[agentdark45]

How I feel right now:

[Utroll]

Well ...technically ...you're in the bug report / bug resolved.
Lock and trash.

[Ondra]

this needs to be preserved for future generations

[Ondra]

Getting kinda boring and repetitive. Plus he accidentally mixed his "real" identity with his "xforce" fake profile - his registered email is xforce@mail.com.

[loocas]

He's forgetting about me...

[vkiuru]

Regarding posting those emails in public, Keymaster, you really should rethink your current approach. Might not be worth it in the long run.

EDIT: Oh man, just take a break from whatever it is you're doing and read this page and the one before it. People dogpiling that guy and memes. You need a public relations guy and you need it fast.

[VRAY FOR EVER]

Ha Ha Ha funny topic love this guy - 3d studio
 loocas do not worry nobody forgot you

[Ondra]

I'm glad you are still sore about this :D
