Thread: How to Pan accross still images (Ken Burns)

  1. Default How to Pan accross still images (Ken Burns)

    I am trying to pan accross a still image a la Ken Burns using the pan / crop window but it is not easy.

    Here is how I attempted to do it

    A movie of the process (39MB!)
    http://ds21.cc.yamaguchi-u.ac.jp/~ec...p/kenburns.swf

    1) I have to calculate the distance to the end of the pan (by pressing the cursor key hundreds of times)
    2) Insert keyframes ever .25 of a second or so.
    3) Divide the distance to the end of the pan by the number of key frames: e.g. if it was two hundred key frames to the end of the pan and there are twenty key frames then the increment is 10 cursor presses
    4) Go to each keyframe and move the F frame accross by the increment calculated in 3.

    It takes a long time. Is there a wizard? A quicker way?

    Why are you doing this? Keyframe #1 at the beginning of pan KF #2at END of pan? Done. Why all the interim KFs?

    If I COULD d/l your swf file I might see your dilemma! But at present I can't? Is it a VERY big SWF?

    Thanks a lot! I should have tried that.

    Yes the swf is very big. I have replaced it with a smaller one showing the right way to pan accross a still image.

    Tim? I can't access your "result"?

    In P/C try experimenting with:

    1 - Having the Synch Cursor icon enabled

    2 - Right Click on the K/F and pick a different motion action: Linear, Fast, . . . Hold

    3 - Different degrees of Keyframe interpolation - 0 > 100

    You might as well try out Track motion for getting even MORE manipulation with stills!! You can then start wandering about in 3-D space too!

    Sorry, I had the wrong file type. It should have been mp4. It is correct above now.

    > 1 - Having the Synch Cursor icon enabled
    That is handy. Shows you where the pan is at in the little time line at the bottom.

    > 2 - Right Click on the K/F and pick a different motion action: Linear, Fast, . . . Hold
    I am trying that. I guess that it is changing the acceleration and speed of the movement but I can't really tell! I found the help file.


    > 3 - Different degrees of Keyframe interpolation - 0 > 100
    The higher the number the jerkier it is. Mmm..

    > You might as well try out Track motion
    I have a long way to go. I tried it but again I could not see what was going on.
    (I need a second monitor. I wish there were a button for making the preview window bigger in a flash. )

    Should you have time..Is there a way of doing movement in real time? E.g. lets say i wanted to zoom in on a moving person. Would I have to do that by creating key frames and following the person around in a sort of join the dots fashion. Or is it possible, using a plug in possibly, to play a preview and for vegas to save the pan position creating a series of key frames or a path in real time?

    Thanks,

    Tim
