Bad edge movement

[markomarko]

Output to stills, animation made in Premiere. Same pal settings 25fps in 3ds max and in premiere. tried with several aa filters, this one is with video. And i keep geting those problems (i don't konw how to call them) with (vertical) edges jumping on moving objects. I've tried with motion blur but i keep getting the same results. What am I doing wrong. Please help me.

 

If there's a name for this kind of problem would be grateful if you tell me.

Moire pattern

[markomarko]

thank you very much

[markomarko]

how to reduce it, or how to fix it?

Looks like interlacing, though it kind of reads as motion blur since the image is moving horizontally across the screen. Though I am not 100% sure.

 

If you have no plans to go play this on a cathode ray television, then use progressive scan rather than interlacing. More than likely need to change this when you are exporting from premiere, though there is a slight chance you are rendering in this fashion. Do your frames show this also, or are they clean?

[markomarko]

I have tried with clean frames and with blured frames and i keep getting same result. I have tried with shutter speed 180 and 25 so that it matches 25 fps but same thing happens. I'll try progresive scan.

[markomarko]

Same thing.

I have tried with high settings and with low render settings. With all sorts of AA's. Heard that for animation is best to use Area or Video, and i have tried that too, but i keep get the same result. I really don't know where to search for source of problem. Is the problem in premiere or in vray settings?

you need higher AA settings in vray

Same thing.

Can you post one of the frames before it has been brought into Premiere?

1. No Blur - Video AA jpeg

2. Motion Blur - 8 subd - Video AA png

3. Motion Blur - 8 subd - Video AA - Shutter 25 (25fps) png

----------

Evry one that I have rendered into video has the same problem. I've tried to think to render to 50fps then im premiere to put it to 25 somehow. Don't know, but there has to be solution.

Maybe better AA it's on default -1,2?

looks like a background issue to me now i see the frames. hmmm

 

try saving as TGA - not PNG, and make sure you always render on black background (especially if you are comping) with premultiplied alpha checked.

 

actually its shitty AA as well, use DMC when using motion blur, try 1/10 with a clr threshold of 0.005

Thanks i will try and send you report when i render it.

[markomarko]

It looks better, i'll try to up some settings like vraylght subd and when i render it i'll post it here.

Are you using Adaptive QMC and area filter

It might work.

[markomarko]

the same problem came up with my other project in wich i don't use 3ds max. I use After effects and same problem ocured. I have a picure (jpg, tiff, tga tried all sorts of extensions) of bottle and she goes from bootom of the screen to the top. Same thing happens, edges keep to oscilate, jump, same thing that happend in the video i have posted. Then i've tried to put to horizontal motion and same thing happens. I have looked closely to all sorts of tv commercials and some of them have the same problem and some don't.

 

How to solve the problem? I wonder. I have tried with third party encoder and same thing happens.

[Crazy Homeless Guy]

And you are positive you tried progressive scan, and not interlaced the video on export.

[markomarko]

This problem really makes me angry. I've tried even progressive scan and i still have the same problem.

[markomarko]

I'll try to export from ae to stills then import them to Sony Vegas, maybe there will be less problem, but i really don't think so. There has to be other solution.
