You could do your own tests on your system to see what works best for you.

I have found that PNG takes too long to compress and decompress, while tiff takes a long time to read and write to the...

If you do an image search for tracking marker you will probably come up with something that looks like this : http://www.flickr.com/photos/alba/2505310839/

In my experience these are the worst,...

Yellow markers means that your green and blue channels are not affected by the markers and all of your marker data is in the Red channel. This is good when you have a 4:4:4 workflow but could come...

It looks like you are pouring motor oil into a martini glass.

You could warp your reference sequences with a grid warp or something so that they line up with your mesh.

It's faster to shoot without having to setup a screen and you get all the natural light with no spill. Sometimes the tradeoff of one less day shooting is worth the price you have to pay to do the...

Off the top of my head I would suggest replacing your video card with the same brand of card that came out of your machine. So if they pulled out an Nvidia card replace it with that.

FCP and...

@radders, I see your point, but for my tests I was not looking at percentage differences and I don't really want to setup a batch process of 20 renders at 1 hour each to figure this out. What I was...

OK I improved my methodology and setup a fairly complex scene (finalgather, reflection, refraction, all mia materials), I set the verbosity output level on the batch renderer so I could see what the...

Did a few tests where every surface had mia_material_x_passes and output 5 passes to the hard drive. There wasn't any noticeable difference in render time, 24 seconds each time. I've been doing...

I wonder if using materials optimized for the renderer, like the Mental Rey materials that support passes, dump out render passes faster then trying to get buffers out of a Lambert shader...

I think you are on the verge of uncovering a mass renderpass conspiracy perpetrated by the cult of REY.

I've never gone crazy with passes so I've never really noticed the giant render hit and when...

Using Maya 2012 and Mental Rey on OSX: I added Diffuse, Spec, Shadow, Indirect, and reflection. I rendered all my passes out to .JPG My test scene went from 50 to 74 seconds. I guess that is a big...

Interesting thought, I went through the Dell Alienware configurator to see how a a 14" Alienware would compare to a 15" MacBookPro. I figured out about $1600 for the Dell and $1800 for the Mac. The...

You could run your footage into the background (bg) input of your scanline render node.

I haven't used Bullet but I can tell you that without any air resistance your objects should accelerate forever just like you show above. Terminal velocity is the phenomenon when the force of air...

These guys did it the other way around:

But they planned for it, and had actual reference of...

I agree, it completely depends on how much work you want to do, what your budget is, and what the shots are.

Another thing to remember is that a glass surface would reflect a small portion of the...

This is what you initially posted:


My response was that the way Red's single CMOS 4K beyer pattern sensor works similar to the Genesis single 5K striped sensor. It is a single large chip and...

I totally agree, they made it easy on me by wanting ProRes back out the other end of my VFX pipe. Whenever you change formats there will be some information lost somewhere, but in your case it would...

I did this not too long ago and I read them in and out at gamma 1.8 so that they would look the same coming out of Nuke so that the VFX would look the same (or at least really close) next to the...

Firstly:
All digital and film cameras have extra noise in the blue channel compared to the red and green channels.

Secondly: I love Rian Johnsons movies, but please do not spread this article...

More info on Debayering, or technically demosaicing: http://en.wikipedia.org/wiki/Demosaicing

Remember that the Red sensor is a Beyer pattern and it looks to me that these artifacts are more likely caused by Debayering than image compression. As much as Red likes to talk about how super neat...

You could make a rotoshape that reveals the letters. Not so useful when someone wants to change the text.

I am sorry to say this but there are some things that are easier and faster to go out to...
