8-11 Saving Images to Mass Storage
Image sequences may be saved as CAP files (p r oprietary raw format, see “Appendix K: Partitio n
Capture (CAP) File Format” on page 91), as AVI videos, in which one file c ontains all the frames
of the sequence, or TIFF, JPEG, or BMP stacks, which are collections of files, one file per fr ame of
imagery. The file s a ve options chan g e s depending on whether or 8-bit or 10-bit image data has
been wri tt en to internal high-speed memory:
10-bits recorded 8-bits recorded
TIFF (8-bit M /24-bit C) or RAW TIFF (16-bit) TIFF (8-bit M / 24-bit C) or RAW TIFF (8-bit)
DNG (16-bit raw format) DNG (8-bit Raw format)
BMP (8-bit M /24-bit C) BMP (8-bit M/ 24-bit C)
AVI (8-bit M /24-bit C) AVI (8-bit M / 24-bit C)
JPEG (8-bit M /24-bit C) JPEG (8-bit M / 24-bit C)
CAP (10-bit raw format) CAP (8-bit Raw format)
Calculating file s iz es for TIFF and BMP images is very simple:
Resolution x Bit de p th/8 = approximate BMP or TIFF file si z e in Bytes
(to convert Bytes to KB divide by 1024)
For example a 1280 x 1024 Mono BMP or TIFF is:
1280 x 1024 x 8 / 8 = 1,310,720 bytes = 1,280K
A 1280 x 1024 16-bit RAW TIFF/DNG is:
1280 x 1024 x 16 / 8 = 2,621,440 bytes = 2,560K
CAP files a r e always the size of the current bu ff er (session size).
The actual file si z e of a 1280 x 1024 mono BMP or TIFF is about 1281K (the additional 1K f or the file
header). The actual size of 16-bit RAW TIFF is 2561K (again add an additional 1K f or the header).
Note: The RAW 16-bit TIFF saved from the camera actually has 10 bits of image data. The 16-
bit format is used for compatibility r easons.
Calculating file s iz es for AVI and JPEG images is much more difficult. The c ompression is o ft en
approximately 10x to 20x, but it can be much greater for images with little c ontent, and it can
be much less for very complex images.
RAW images are not colorized, so Mono and Color images are the same size. Colorization
inc r eases file si z e 3x because 8 bits are saved for each of red, green, and blue channels.
To Save a recording to a connected mass storage device on the TS3:
1. Make a recording and establish the Start Clip and End Clip points you wish to use (see “8-8
Reviewing Captured Imagery: Playback” on page 68).
Note that the frame numbers initially sh o wn in the dialog box will be the actual start and stop
frames for the enti r e capture
unless
the Start Clip and End Clip bumpers have been moved. If you are
not sure what the actual beginning and end frame numbers for the clip are, you can find them on
the far left / f ar right sides of the Clip bar.
