To avoid this when loading a file, ensure that [Freeze

Importing or exporting files to or from frame
memory
Import:
Imports a file in a different format from a local
disk or removable disk into frame memory after
changing its format.
Export:
Exports a file in a register to a local disk or
removable disk after changing its format.
You can import the following types of files into frame
memory.
SDTV (480i)
Images 720 × 487 pixels in size are exactly the size which
fills the full screen.
The following figure shows how an import image is
processed when the 480i/59.94 format is used.
Images are placed with the upper left of the screen as the
origin.
When an image is smaller than the screen, the remainder of
the screen is filled with black. When it is larger, parts
which extend beyond the screen are cropped.
720 pixels
487 pixels
Position of small picture
Parts discarded when image is
too large
Section filled with black for a
small picture
No pixel ratio conversion is performed when images are
imported for the SDTV format.
When the signal format is 480i/59.94, if you create an
image with a size of 720 × 540 on a computer and then
import it just as it is, the image will be too tall. To maintain
the shape of the image, first create it as a 720 × 540 image
and then use computer software tools to compress the
vertical dimension to 487 pixels before importing it.
Notes
This functionality has been tested and confirmed to work
with TIFF files created by Photoshop, but it may not be
possible to use TIFF files created with some other
software.
About import image size
Pay attention to the following, depending on the signal
format which you use.
HDTV (1080i)
Images 1920 × 1080 pixels in size are exactly the size
which fills the full screen.
Like SDTV, images are placed with the upper left of the
screen as the origin.
When an image is smaller or larger than the screen,
processing is the same as for SDTV.
Since the pixel ratio of the HDTV format is 1:1, files
created on computers are imported in their original shapes.
The following table shows the image sizes which exactly
fill the full screen for the various signal formats.
