Supported File Types for DRAGRI

Video file.aviMicrosoft's AVI. Depending on the compression system (codec), it may be necessary to install an appropriate driver in the computer.
.mov Movie in Apple's Quick Time format. Quick Time must be installed on the computer.
.mpg .mpeg DRAGRI is compatible with MPEG-1, ES, SS
MPEG-2, ES, PS, TS MP@ML, SP@ML 4:2:0
Image file.jpg Internationally standardized format for an image file. This is lossy (irreversible) and image quality may be degraded if a high compression ratio is used for natural images, such as photos and videos.
.gif UNISYS/CompuServe's image format, which can handle up to 256 colors. DRAGRI can handle a transparent GIF but cannot handle an animated GIF.
.png A license-free image format, which can handle from 256 to the maximum number of colors. Since this is lossless, no degradation in image quality occurs.
Audio file.auAudio waveform file in Sun's μ-lawDRAGRI is compatible with 8-bit, 8-kHz, monaural sound.
.wav Windows audio file.

Tips for Taking a Video

Taking a video so that a high compression ratio can be obtained.

Choose a simple background. (If the background is complicated, the video file becomes large.)

Put your video camera on a tripod to keep it steady and avoid a moving background.

Turn the AGC (automatic gain control) or AE (automatic exposure) off and set the brightness manually, in order to stabilize the luminance of the background for the duration of the video.

Taking a video suitable for using DragMotion

For an item of DRAGRI content in which an object moves, fix the camera's distance to facilitate later editing. If you pan or zoom to follow an object, the movement of the object becomes discontinuous, and it is difficult to draw a drag path.
