Stabilization

[user_deleted]

I `m trying to stabilize a plate. I managed to improve the footage using several stabilize nodes, but it is still sligthly shaking. I wonder if someone can suggest a trick to get rid of the shaking.

Thanks

In the tracker turn up the sub pixel resolution, turn on "preprocess" with a blur of like 1-3.

That makes sense, I will try.

Thanks

if you need several nodes to stabilize the footage chances are that you use an unfortunate tracking point and/or have a lot of motion blur and/or very noisy/grainy footage.

not a lot you can do about the motion blur (maybe try the SmoothCam node?), but sometimes you get lucky by using a Reorder to track only the channel with the least noise/grain.
preprocess (or a blur node) can help as well.

In the cookbook you can find a useful macro called pretrack, it's similar to the preprocess but more visual. If it doesn't work try to use a subpixel res. 1/512 or above to get more accuracy.

Another option that works on untrackable shots is to look at using a 3d tracker pending there aren't a huge amount of people walking across the frame and lots of objects moving independently of the camera move.

Boujou for example will let you pick 4 of the tracked points and export it as a stabilize node. Also Shake 4 allows you to import this tracking data into a multiplane node.

It really depends the shot though. Doesn't work with all situations.

well i I tried the first suggestion and it worked really well...i think that just increasing the subPixel Resolution in my case was enough.

Thank u guys!

The shake have a option to average the data of multiple trackers, useful for this type of operation
