Ken Burns effect

Offline
#1 Sylvain Girardot
I didn't understand the way to make Kern Burns effect with LRT4 with the 5 stars tag.
Could someone explain to the community??
Thank you ++

There are some options for Ken Burns in LRT5:

1) If you just set different crops to the first image and the last image (with 4* keyframes) LRT will calculate the Ken Burns animation from start to end (and ignore inbetween keyframes for the crop). This is the easiest way and recommended, if you only want a linear pan or zoom.

2) If you need more then one keyframe for animating the crop, then just use 5* keyframes for this - those keyframes will only serve to animate the crop and not the other tools. So if you want to do a 3 point Crop animation, just set the first frame, one in the middle and the last one as 5* - the crop of those keyframes will be used to calculate the ken burns.

One last recommendation: because of Lightroom way of cropping I recommend doing slow 2point animations only, best without animating the rotation. So a slow pan or zoom from start to end would work best, where the angle is constant.

I tried the above steps...i am still not seeing the linear pan happening. i had only 2 4* keyframes and i cropped them. it is still not panning.

on other note, i don't see 5*keyframes at all. i see only 4*keyframes. am i missing something here...plz advise

If you have 2 4* keyframes, just set a crop to the first, copy the crop to the last, then move it or resize it (keep the same aspect ratio!). Then save the metadata for those keyframes in Lightroom (as always from grid view).

Then go to LRT: reload. Check the first frame, you should see the crop as orange rectangle in the preview. Go to the last frame, you should see the other crop there. Now apply the auto transition.

Select all images in LRT (Ctrl-A) - you should see the crop animation in the preview as overlay of orange rectangles.

Save and finish the workflow.

PS: If you want to use more then 2 keyrames for crop, you would have to manually create 5* keyframes. In that case exchange the 4* keyframes at the beginning and at the end with 5* ones (in LRT press "5") and add another 5* keyframe somewhere in the middle. In Lightroom you would then have to set your keyframe crops to those 5* keyframes, otherwise it's the same.
