Drag the slider or enter a value for Keyframe Interval to control the frequency of keyframes
3.
(frames with complete data) in the video clip. For example, with a keyframe interval of 30, Flash
stores a complete frame every 30 frames. For frames between intervals, Flash stores only the data
that changes from the preceding frame. With smaller intervals, you can fast-forward or rewind
more quickly to a specific frame, but the file size is larger.
Note: A keyframe interval of 1 stores a complete frame for each frame of the video. This setting is
recommended only for very small video files.
If you are encoding the video using a bandwidth value, select High Quality Keyframes to ensure
4.
consistent image quality in keyframes. Using a consistent bandwidth speed can reduce the
quality of keyframes if you do not select this option.
Select Quick Compress to reduce the time it takes to compress a file. Increasing encoding speed

can also decrease image quality.
Select Synchronize Video to Macromedia Flash Document Frame Rate to match the playback

speed of the imported video to the playback speed of the main Flash document Timeline.
Deselect this option to prevent frame rate synchronization.
Select a value for Number of Video Frames to Encode Per Number of Flash Frames to specify
7.
the ratio of imported video frames to main Flash Timeline frames. For example, to play one
imported video frame for every main Flash Timeline frame, select 1:1; to play one imported
video frame for every two main Timeline frames, select 1:2.
Dropping frames from the imported video does not slow down the motion of the video.
Instead, it shows fewer frames per second, so that the video appears choppy during playback.
