Remainder it is not known, if, but the QuickTime prayer is used, it is possible to modify the refresh rate of image and music.

As for refresh rate although it can modify, to 3 time speed a n/a

But, depending upon the contents of animated picture there are times when we would like to increase refresh rate more and more.To tell the truth, as for this refresh rate it is to be possible by the fact that AppleScirpt is used to make 3 time speeds or more.

The script of QuickTime Player is used

First, after the script editor (it is in application /AppleScirpt) starting, it puts in a state where just intended animated picture has opened with QuickTime Player.AppleScript below is executed next on the script editor just.Because they are 3 lines which pass, without fearing, it will challenge!

tell application “QuickTime Player”
set preferred rate of document 1 to 16
end tell

in this, 16now double speed playback. QuickTime Playerplease try to press the play button on the. of the above script16can make changes to the number of, playback speed can be changed freely.
tentatively34make up to speed about (34that second video1can play in seconds) i have, whether it is possible to change the playback speed up to where? is not confirmed. (in reverse1/2if you want to or are0.5suppose you)
