You can set a save attribute for each frame.
For example, the save attribute can be set in the following cases:
Each frame on the timeline is marked with ,
,
or
as in the following figure. This mark indicates the save attribute of the frame.
Normally, the mark is black. If the user has reduced a frame in a section or set the attribute for the current frame, the mark is displayed in red.
Each mark is described in the following table.
![]() | Differential compression frame | DRAGRI compresses the content by not saving parts where an image has little variation between frames. This is called "differential compression." The frames with this mark are saved compactly using differential compression. |
![]() | Key frame | The entire screen of a key frame is saved without differential compression. A key frame is automatically set for the first frame on a drag path and the frame for which autoplay starts. When you set a key frame for the end frame on a drag path manually, the visual effects can be improved. When you make a frame with perceptible block noise a key frame, the image quality can be improved. |
![]() | Skip frame | A skip frame is not saved and is excluded from the content. A skip frame is used to thin out unnecessary frames individually or delete a frame where an object's appearance is unacceptable. |
![]() | No scramble | A frame with this mark is output as a JPEG file as it is without scrambling. This frame is convenient for retouching an image later. |
No mark | Skip frame | ƒ}Like a skip frame, a frame without a mark is not saved and is excluded from the content. |
To set the attribute for a frame, use the following options from the [Edit] menu:
This sets frame reduction for the entire video content.
The number on the left indicates how many frames are displayed. When the number of frames is 1, every frame is displayed.
When it is 5, every 5th frame is displayed. The number in parentheses indicates the total number of frames.
This setting is used when the content is played.
This sets frame reduction in the section specified by the IN point marker and OUT point marker. Make the IN point a key frame and then set differential compression frames at intervals for the set number of frames.
Clicking the [Unset] button undoes the setting of the section.
The attribute for the current frame can be set manually.
Differential compression frame | Sets the current frame to a differential compression frame. |
Key frame | Sets the current frame to a key frame. |
Skip frame | Sets the current frame to a skip frame. |
No scramble | Sets the current frame to a frame without scrambling. |
Unset | Undoes the manual setting for the current frame. |
