I am using the exact same SGI image sequences as input for testing, so
for the sake of completeness, I'll post the commandline I've used, here too:

The general command would be:
"ffmpeg -f image2 -start_number $START_NUMBER -i %05d.sgi -an -f $FORMAT
-vcodec $VCODEC -g 1 -pix_fmt $PIX_FMT $OUTPUT_VIDEO"

There's a forum entry describing the actual commands used for generating
YUV and RGB output of the SVT collection:

Additionally, I've put the framemd5 checksums of different pix_fmt
variations online for verification:

I haven't had the time to verify that output matches the source, but
both checksums are in there, so...

If you happen to be able to suggest a proper output format for storing
>8 bits-per-components uncompressed in an interoperable container/codec
combination supported by ffmpeg, I'd be happy to hear from you :)
