Batch Cropping?

1) Crop the first image.
2) Under the Metadata menu select "Lift Adjustments"
3) Delete all the adjustments (highlight the row and delete key) EXCEPT for the crop.
4) Select all the images you want to crop the same way.
5) Click "Stamp Selected Images"
6) Wait for "Processing..." to finish.

This only works if they all receive the exact same crop, of course. If you have to tweak the crop for all the images, then there's nothing else but doing it manually. Since you said it was time lapse, then you likely want the same crop.

And here's my modest suggestion, old question but contemporary problem yet...
Since you cannot just resize the picture as is, even with an anamorphic setting, that would stretch it, the only way to achieve a 16:9 aspect ratio is to crop it.
For example let's say that your pics are 1700x1100. To get a 16:9 AR you need to crop 200 pixels vertically and 100 horizontally. How and where you place those cropping settings depends on you and on the pics.

But i know only one tool that can do that by bulk and designed specifically for cropping:
Photo Cropper by Moonvalleysoft

google for it, but try the demo first, you can't go wrong then.

And just to clarify, when you delete the adjustments, delete the ones in the list that pops up on a separate window, not the photo adjustment on Aperture's HUD.
