Can't figure out how remove unwanted objects in ocean footage
on Jan 30, 2011 at 2:46:04 am

Hello and thanks in advance for any help.

Let me start by saying my brain is fried. I'm using After Effects CS5.

Here's my situation:

I've been given some footage of a man who is suppose to be on an island. The problem is there are back ground elements such as boats, fisherman and in some of the footage condos from a near by beach.

Anyone know an easy way to remove said ojects and still keep the footage looking consistant?

Problems: The camera is shaky.
The actor is moving in front of the objects at random time.
The clouds, sky and water are all very distint, so cloning is very obvious.

I've tried using Mochha to track the objects but it gets lost when the actor cuts infront of the object.

I've tried the rotobrush with the actor but it keeps crashing my system.

I've tried using CC Simple Wire Removal but the because of the horizen it looks obvious they it's mirrored.

Anyone know of any way to help? Or maybe a plug-in that can help?

I know I'm probably not making much sense but as I said, this seems like there should be a simple solution but I can't figure it out.

Thanks again

One issue at a time. First off is removing the unwanted objects. If the rotobrush isn't working, then I don't see any choice but do the roto by hand. Post a frame, and maybe I'll think of something.

Second, in Mocha try tracking something besides the object itself. Hopefully something like this exists and is on the same plane as the boats, etc.

Third, replacing the object. In more complex situations, I generally don't bother with the clone stamp in AE. Instead, I open up a frame in Photoshop and do the cloning there on a separate layer. Then take the patch layer and apply the tracking data (or match move) it with the footage. You'll have to play with the grain, etc. to make it match the video, but in my experience this gets much better results than trying to clone from the video source.

All good advice from Olin, here's a few more tips:
It's not going to be easy, so don't expect a quick fix.
If the camera is a bit shaky, like a hand held pan or tilt that is not perfect, then stabilize your footage before applying effects. After you apply effects, ad the shake back. If the camera goes nuts, you may want to try using SynthEyes or Boujou for tracking.
For roto- Mocha does a great job- much faster than doing it by hand and there's a lot of info out there and tutorials on this.
My approach would be the same as Olin's- create clean plates in PSD and comp them back using tracking data and adding grain.

There is a match grain effect that works pretty well.

Tough to give accurate advice without see what you've described. Can you post an image from your footage?
