Pan/Crop goes off screen

I've got a class photo I'm using in a project and need to Pan and zoom to the far right hand side of the picture. I'm using Event Pan & Zooming to the student over about a 7 second shot but when it zooms and pans, it goes off of the right hand side of the screen(black bar on right for a while ) and then comes back to the subject. How do I zoom just to the subject but not go off the screen?


Thanks in Advance

Hi doormill,

You might try reducing the smoothness value in your pan/crop keyframes, the lower the number, the more linear the motion.

Thanks but this didn't help a lot. I had to reduce the first keyframe size(zoom in) and then add a middle keyframe at the point where it was about to go off the screen and size it down a little as well. Not quite as smooth but it worked pretty well. Thanks for your help.

Have a good day!!!

If you're going straight across set the smoothness setting to 0.00 which will cause the pan to be perfectly horizontal. Do NOT add any key frames along the path. Only set the first and last keyframes. If you have set some, use the (-) minus key to take them out.

The pan will "stop" where you set the last keyframe. Use the crop/pan controls as needed. See my little moving map tutorial to see how much control you can get.

Thanks

Well it's not perfectly horizontal with a slightly upward motion but if I set just the first and last keyframe, it goes to far to the right and then comes back. I'm not at my computer now but I will try this with the smoothness set to 0.00 and see what happens.


Have a great New Year!!!

Without seeing your project all anyone can do is guess. If your pan goes too far or goes right, then pauses and then goes back left or moves up and down and that's not what you want it to do, then YOU didn't set keyframes correctly or you have them at the wrong place or there are too many keyframes. The reason I suggested you only set a first and last keyframe is Vegas will automatically fill in the intermediate frames which should result in a very smooth pan. If you set 'tweener' frames, then you need to set them carefully or you can get a bad case of giggles.

Hint: watch the Event/Pan crop window to observe the size and center settings as you pan through your event by holding down the Alt key as you press the keyboard left and right arrow keys to advance one frame at a time. If you want to go straight across and not up or down, be sure there are no changes in the values other than what advances the pan in the single direction you want to go. Also be careful that the cursor is on the timeline, not controlling the FX window or pressing the arrow keys will instead nudge the settings, not the move on the timeline.

If you do not want to pan across the entire picture, your last keyframe must be set at the point you want the pan to stop.

I pointed you to my tutorial to show how flexable panning and zooming is in Vegas. Check out Kelly's (Chienworks site) for the actual video). Also try doing the Vegas tutorial and read the full manual pages 66-68 that covers the basics of pannning.

Thanks, I understand(I think) how it works and all I did to start off was exactly what you are saying. My first keyframe is not changed from original. I then added 1 only last keyframe and then I set the zoom and crop to where I wanted it to end on the last keyframe. I added nothing in between. The picture I'm using I need to zoom and pan to the far right hand side of the picture. On my last keyframe(only other one besides the first unchanged one) I zoomed and cropped so the right hand side of the crop frame was just to the left of the right edge of the screen but not going off. I then previewed it and it would zoom and pan across but each time it went off the right hand of the screen slightly and then came back on. If I check spots as it is zooming and cropping, the problem seems to be the crop size doesn't get small enough fast enough to keep the right hand side from being in the black off the screen. To repeat. 1st keyframe is full picture no cropping no panning no zooming and the only other keyframe the last one is sized and panned to where I want it to end.

I had to shrink(crop)the size of the picture in the first keyframe from full screen small enought that when it starts moving in and panning, it gets small enought before it gets to the end of the zoom so the right hand side is not off the screen while keeping the student from going off the left side of the crop frame. I'm not zooming in on something and then start panning across. If you can picture this, It is a wide picture of kids in a class room about 8 rows wide and 6 rows deep. The student is on the last row to the right and almost to the right edge of the picture.

I'm sure I'm missing something but I do have a general idea of how it works and have used it many times but never when it's this far to one side. It doesn't really go off the right and then come back so much as the size of the crop isn't small enough while zooming to keep the right hand side of the crop frame from being in the black.

Thanks in advance for any help.

Many Thanks to GG and all

I had done it all as you described except changing the smoothness to 0.00. I did lower it but not nearly enough. I assumed(you know where that gets you) that the higher the number the smoother it would be, not the other way around. Changin to 0.00 worked perfectly.


Hope I didn't ruffle any feathers.

Happy New Year to all.

I ran into the same thing. Just set the first and last keyframes and then grab the vector path that is drawn in the pan/crop tool and shorten it. Maintain its direction, but just shorten it.

I don't fully understand the function of this vector yet but this works.
