I don't know of one. And there's not a "pan/crop" flag that says it's been changed. I suppose you could take two points and see if the width and height match the video event media width and height and verify the rotation is zero.

@RedRob-CandlelightProdctns, I'll write up a tutorial on this to explain everything but this seems to work. I'll show all the test cases in the tutorial.

Ed -- as always, you're an amazing human being.

Thank You

Possibly could have simplified to see if any events have more than one keyframe on them, but yours is much more precise in what it's looking for, and actually checking to see if those changes occurred.. love it!

@RedRob-CandlelightProdctns I did notice that if it has more than one keyframe and none of the keyframes have been changed, the icon on the event will be lit up but the script will not select it. So change:

if ((pcwidth != mWidth) || (pcheight != mHeight) || (vKF.Rotation != 0.0))

to

if ((pcwidth != mWidth) || (pcheight != mHeight) || (vKF.Rotation != 0.0) || (vKFCount > 1))

Spectacular! No need for a more robust write-up (for me), but if you're so inclined and think it will help others, go for it! :-) :-)

With your script in my back pocket I quickly solved a subsequent problem; I needed to rotate all my media from a camera by -.6 degrees.

Vegasaur has nifty tool to change the rotation on all selected clips, but it only permits whole numbers, not very helpful here. So I used Vegasaur to change the rotation on all my events for this one media to 1 degree, then used the framework of your script (above) to say "for all events with a keyframe of 1 degree rotation, set the rotation to -.6. In the process I realize I had to convert degrees to radians (the API does mention radians) and it worked like a charm!

That's great! Another area is changing the audio volume. You have to convert to/from DB.

@RedRob-CandlelightProdctns, this tutorial just went live this morning!
