NEED HELP WITH Mental Ray 1.5 Render

[meshman]

why do you need to render into avi? why dont you just render it into frames and make an avi later using lets say after effects?

Cheers

hehe, i had exactly the same problem yesterday. Here is a quote from the Mental Ray for Maya helpfiles:



Unsupported Output File Formats

Limitation

mental ray for Maya does not support the following output image formats that are supported by Maya:

AVI
CIN
GIF

When the Derive from Maya framebuffer setting is being used, and an unsupported output format is selected, mental ray for Maya will select a substitute format. A warning message will be output to the Script Editor to describe the substitute format that was selected.

Workaround

Maya's imgcvt utility can be used to convert images to most of the unsupported formats.




You can watch the animation of the image sequence in Maya's FCheck but you can't export it :thumbsdow

Like meshman said you have to use a 3rd Party program like Adobe Premiere or Iridas FrameCycler in order to create a *.avi (or any other format) from your image sequence.

or you could spend a lot less money and get quicktime 6 pro and export to a .mov

obviously not as good as premiere of after effects but for simply making a movie file, it's fine

Thx for all suggestions, i think it's good solution with After Effect,
If you could explain me the procedure...:thumbsup:

Render your animation to frames (tga, tif, jpeg, etc)

In after effects,

File > Import > File...

Select the first frame and then in the dialogue box, select the "sequence" option, depending on the format you rendered your frames, there should be a check box for:

TIFF seqence, JPEG sequence, etc.

If its 3d footage you want to use in a comp, have AE interpret the alpha as Premultiplied

If you need to change the way AE interprets footage, select the sequence in the project window and select File > Interpret Footage > Main... from there you can specify Alpha, Frame Rate, Fields, Pixel aspect ratio.

When your ready, you can render your comp in a number of formats, you can also select File > Export > AVI...
