You can zoom in/out in post processing if you animate your crop with LRTimelapse.
If you want to do it in Hardware, you will need a doller on a rail or slider...

It's the same as modifing any other parameter (as shown in the tutorial).
Change crop of image one (orgin of zoom),
sync to all images,
change crop of the last image (destimation of zoom),
write out metadata
In LRTimelapse hit one of the transitions.
Select all images and you will see the zoom-transition in the preview.
Save
Reload metadata in Lightroom
Export video.

Hey,
I tried that and it doesn't seem to work for me. I'm trying to get the effect of zooming out, so I start with a cropped image, sync that to all images, then for the last photo, i don't crop it at all. When I get the transition in LRTimelapse, it doesn't REALLY look like it's zooming because the frame size becomes bigger. Is there a way to make all images have the same resolution as the smallest cropped image?
Thanks!

Ah, I found a solution in case anyone else is having the same problem, although it may not be the most efficient way to do it. I crop the first image, sync it to all images, then un-crop the last image. After doing "linear transition" in LRTimelapse and saving it, you read the metadata in Lightroom. At this point, the images go smoothly from the crop size to the un-cropped size at the end. But of course, the resolution changes with each image too.
From here, I just exported all the images to another folder, since when you export, u can resize all the images to the same size. Then I import the re-sized images from the new folder, and export it as a video.
It's not ideal, but it works, and doesn't take that much longer. But if anyone has figured out a better way to do this, please post!
Peace!

Honestly I don't understand your problem. Don't need the intermediate step, just do like you did but don't remove the crop on the last image (that might confuse lightroom) instead make it only slightly smaller than the full image (normally you would crop to 16:9 anyway.
Now apply the transition in LRTimelapse - you wont see a real zoom in the lrtimelapse preview, but you will see the crop rectangle grow or shrink when you pass thoug the sequence.
Save everything an reimport to LRTimelapse. There the now different crops will be applyied. The different resolution doesn't matter anyway. When exporting as video, Lightroom will shrink larger images to the output resolution.
Caution: you shouldn't set a crop smaller than the resolution of the output video (hit I to see the resolution of the cropped area in LR) becaus on video export, LR wouldn't blow smaller images up (I could imagine that this is the effect you ran into). There is an indicator in the LRTimelapse preview as well that will tell you if your resolution is not sufficient.
