About File Format for FumeFX - gakkie - 07-08-2010
Hi. I'd like to ask about FumeFX renderoutput's File format.
Which File Format do you strongly recommend for rendering FumeFX images in 16bit and 32bit colour space??
Im using 3dsMax2010 and FumeFX 1.2e.
Cheers!!
Re: About File Format for FumeFX - gakkie - 07-08-2010
I just put my opinion about each major file format....though (working in AE CS4)
:SGI/RGB:
Fire elements' alpha is eaten for some reason inside AE with the mode of 8bit and 16bit.
:TGA:
It does not contain Alpha Channel, and is 8bit
The image is still 8bit.
:RLA:
it works fine as 16bit, but sometimes has error
is not recognizabe.
:TIFF:
via backburner, it has an error of renderElement rendered as 16bit or 8bit by different users.
:EXR:
Colour changes (because of gamma changes??)
:HDR
???)No Alpha Channel contained
I was using TGA(32bit), however I just noticed that images are 8bit...omg
TIFF(16bit) is good choise for me, but the errors that im getting is a bit of nightmare...
Or am I thinking too much??
I'd like to hear other ppl's opinion...

There is a trap here.
If a format lets you pick between 24bit and 32 bit (like tga) it means that 32bit mode is for all channels together (8bitR, 8bitG, 8bitB, 8bitAlpha)
TGA does not support floating point renders (16bit and 32 bit).
I always use EXR, and I have never experienced those color changes (gamma) between renders.
If you mean that a render in 3dsMax VFB looks different than in PS or AE then it's correct.
You just have to instruct AE to use linear gamma in file Interpret settings.

I misunderstood about 32bit mode for TGA.(i thought 32bit meant be floating point.. my bad XP)
As you said, using linear gamma in file interpert setting in AE, it did work fine
Thanks for reply, Filip.

For OpenEXR, some software will show different color then the original rendered image, washout or the orange will become yellow for exemple. I know that Photoshop, afterFX and Flipbook from softimage changes the color. I think that they intepret the footage as linear.
to fix this:
for photoshop:
In photoshop it will look washed out. To correct, create a New Adjustment Layer>Exposure and apply the inverse gamma correction of .4545
for afterFX:
on your footage, go to interpret footage and the drop down menu "Interpres As Linear Light" put it to none.

When you rendered something without any colormapping - its bringing your image to leaner colorspace and exr-format save all data in leaner colorspace (TIFF, TGA, PNG, JPG, etc - save data in SRGB). Otherwise, all monotors and viewers works in SRGB colorspace. And cause of this exr-files looks incorrect and others formats looks fine.
How you said, you can put your gama to 0.4545 (1/2.2) - looks good, yes, but more correctly issue to fix it - set up 3ds max LUT to gamma 2.2 (viewport gamma 2,2, input gamma 2,2, output gamma 1)

Thanks for Extra info, Wasus and Eric-S.
