Title: Camera rotation shake bug (A6 final)
Post by: stanDM on 2016-12-23, 13:28:15

Hi guys,

we are experiencing camera shake bug during animation again - C4D R18 + Corona A6 final on Windows.

When you animate camera rotation, you get camera "jumps" in the final renderings. Camera animation with no rotation works OK. Here is scene file for testing:

We have tracked the final animation in AE and here is the result - you can clearly see the jumps

Does nobody really experience this? It looks like there is no way to avoid it, even baking camera movement does not help. During rendering Corona always introduces its own random camera movements. It is just couple of pixels, but still clearly visible in the final output.

Unfortunately it means Corona cannot be used for animations where you somehow rotate the camera ...

Wrong unit setup? How is the distance from the 0,0,0 origin?

Well, nothing unusual there, standard units (cm or mm). https://www.dropbox.com/s/fwfrpryqzyzjord/Corona-C4D-A6final-camera_shake.zip?dl=1 (https://www.dropbox.com/s/fwfrpryqzyzjord/Corona-C4D-A6final-camera_shake.zip?dl=1)

It is not scene related, we have tried different scenes with different camera setups and as soon as you start to animate camera rotation, the shaking appears in renderings.

The good news is it should be fixed in the upcoming Beta 1 - see the road map under Beta 1 / Bug Fixes: https://trello.com/b/dgI8vjDb/corona-road-map-cinema-4d

does it still shake if you animate a dummy object attached to the camera instead of the camera?

A test version of the upcoming Alpha 6.2 is available, which should fix the "shaking camera" bug - please test, if all is good, the download page will be updated to this version. For now, links to the download are on the forum post at https://forum.corona-renderer.com/index.php/topic,14938 (https://forum.corona-renderer.com/index.php/topic,14938)
