IMSQ Files
The Autodesk ME Image Sequence (IMSQ) format
isanXMLfileusedbytheAutodeskproducts
Cleaner and Toxik. You generate IMSQ files in the
Render Output group of the Render Scene Dialog’s
Common Parameters rollout (page 3–27) by turning
on Put Image File List(s) In Output Path(s) and
then clicking Create Now. The IMSQ file stores
information about the rendering, including:
• The name of the rendering file
• The format of the rendering file
• The range of frames
(Nonsequential f r ame sequences, such as 1, 7,
12–19, are not supported.)
•Theframerate
•Thepixelaspectratio
• The output t ype, aperture width, and resolution
(w idth x height)
• The render element type and name
• The camera name (when rendering a Camera
view)

JPEG Files
JPEG (.jpeg or .jpg) filesfollowthestandardssetby
the Joint Photography Experts Group. These files
use a var iable compression method that is c alled
lossy compression b ecause of the loss of image
quality as you increase the compression. However,
the JPEG compression scheme is extremely good
and you can sometimes compress the file up to
200:1 without severe loss of image quality. JPEG is
consequently a popular format for posting image
files on the Internet for minimum fi le size and
minimum dow nload time.
Interfa ce
When JPEG is the chosen output format, clicking
Render or Setup in the Render Output File dialog
(page 3–9) displays the JPEG Image Control dialog.
