4-12 Saving Images to Mass Storage
Image sequences are saved either as Patition C ap tures (CAP files), or A VI videos, in which one file
contains all the frames of the sequence, or as TIFF, DNG, JPEG, or BMP stacks, which are collections
of files, one file per fr ame of imagery. Partition C ap ture files (CAP) include all the aw image data in a
proprietary uncompressed format. The file s a ve options chan g e 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)
Note: CAP files a r e only availble on cameras with SSDs, SN A0 and higher.
Calculating file s iz es for TIFF and BMP images is very simple:
Resolution x Bit de th/8 = approximate BMP or TIFF file si 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 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 or the file
header). The actual size of 16-bit RAW TIFF is 2561K (again add an additional 1K 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. Navigate to the Review Menu
2. Select Save. The Save dialog box will appear as in “Figure 4-15: White Balance Dialog”. The Start
and Stop frames for the Save may be edited.
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 Cut In and Cut Out bu tt ons were used during Review. If you
are not sure what the actual beginning and end frame numbers for the video are, you can find them
on the far left / f ar right sides of the record bar. (See “Figure 4-10: Recording Progress: Triggered
TS3”.)
