using "ken burn" effect for astrophotography - screamer - 2012-08-03
Hi all,
here's another tip for using LRTimelapse in an unproper but powerful and useful way.
The main concept here is to "track" subjects in movement manually, and do a sort of raw alignment in time. A classic example is the moon. Then, the sequence aligned thanks to the keyframing capability of LRTimelapse over the crop, can be passed to some astrography software, for stacking the frames together and obtain a single image with more resolution/quality than the original frames.
i've done this experiment today, tracking and stacking a little sequence of the moon moving in the sky, taken with a 300mm, animating the crop of the moon in time, and stacked with the free great tool called RegiStax
The result is pretty impressive (and without the raw alignment of LRTimelapse the stacking software didn't align correctly the frames, because the moon was moving over the entire frame).
Here is the result (click it for bigger but anyway scaled version):

the original one was more big, because registax has a function for doubling the resolution thanks to the extradata of all the frames instead of only one, and the result is impressive

Amazing!
I once did a similar stabilizing for a Timelapse video of the lunar eclipse, if had to reframe I think 7 times because the moon went out of my viewfinder - than I keyframed the crop and got a real steady image without any tracking mount.

Wow,great video!

I just discovered the Themabewertung stars at the top of the forum page and gave this five. It would be great if you could add this to your list of subjects for a future hangout or the like!

When using LRT4, make sure to use 5* keyframes to do the crop animation!
