Controling anti-aliasing and supersampling

[PiXeL_MoNKeY]

A little more info is needed. What are you outputting to? Are you using software renderer or opengl? How much has the footage been resized? One thing I have found that can help is changing the footage quality from Full to Custom and lowering the number below 1.0.

Just a thought,

Hey PM

I'm rendering to Windows Video (.avi) and I'm almost sure I'm using software rendering.

I'm scaling the footage by 67% of it's original size, some times less (80%).

The footage content is 3ds max videos, when I use it in 100% every thing looks perfect, but the problem is how blurry it gets at 67%.

VirtualDub, for example, you can choose in Resize filter a lot of methods like Nearest Neighbor, Bilinear, Lanczos and others.

I'm looking something like this inside combustion.

I've tried to search in help but didn't find anything related to this kind of control.

Any other idea? http://www.cgtalk.com/images/icons/icon11.gif

Combustion does not have any control over the resize algorithms, you can either use the Anti-Aliasing and Supersampling modes or try to set the resolution in the footage controls > output to something below 1.0 using the custom mode, but this doesn't help much in most cases either if you ask me.

If you're working with a file sequence and you just needs to rescale the whole thing, you can try VirtualDub as you mentioned or see if the algorithm in Photoshop does a better job, if so you can process all your sequence in batch.

Hope this helps.

Tnks Diogo!

I'm using combustion since I can scaledown the video and at the same time define a position to it. Combustion give me a greate control to do this king of job in a 8 minuts video, only thing is the lack of a sharp supersampling.

To bad for me, still didn't find anything.

Anyway tnks for your help guys!!

Can you post a frame of your sequence so I can take a look at it?

The AVI is compressed or uncompressed?
Field based or not?
Can't you use the rendered file sequence insted?
Have you tried the Sharpen filter?
