I'm having some issues with hot pixels and am considering building an effects preset that would allow me to select a pixel and have it be replaced with the surrounding pixel's color information. Anyone ever do something like this before? If so, how'd you do it?

What is a hot pixel? Super saturated? Too white or blown out? If you could post a small screenshot I could be more precise in my answer. But you can always setup levels individual controls to do almost anything, mode transfers as sat, alpha, etc. after matte blurs.

It looks like this:

I'm trying to make a preset that will allow me to click and drag around the pixel and have the selected part be replaced with color information gathered from around the area selected.

Any ideas?

Ugh, you mean you have a camera with a bad pixel on the sensor? I hope for your sake it's going into the shop very soon.

Using AE to fix every second of footage you shoot will get real old real fast.

Is it in the exact same spot all the time? Is it always red?

Dave, yeah, it's a bad pixel. Eventually it'll get to the shop, but that wont fix what was already shot.

Chris, it's in the same spots every time. Most are red, some are blue.

I'm imagining some sort of preset that I can drag and drop over the bad pixel/bad area that will adapt to the the footage underneath it.

Here's a quick project file I made. You can turn it into an animation preset or just replace your video with it. It is two cc simple wire removals set in crosshair formation so that they only change a single pixel or two. Simply drag the Null to the center of the bad pixel and you're done!

Thanks a lot. I'll give it a shot tomorrow and let you know how it turns out.

It sounds like you have a potential solution... but this also sounds like a perfect job for our RE:Fill product. You tell us where the bad pixel is via black and white matte, and we'll fill in those pixels with info from surrounding pixels. http://www.revisionfx.com/products/refill/overview/

Note that CC WIre Removal that comes with AE only works in 8 bits, while ours works in 16 bit and floating point. Also, RE:Fill allows you to fill in the pixels with a blend of surrounding pixels, not just offset pixels (of course, displaced pixels might be better in some circumstances, and we can do that too).

WHy don't you try the demo? http://www.revisionfx.com/products/refill/downloads/

Chris, thanks for the help - it's exactly what I was looking for.

Peter, that looks like it could help in the future. I'll check it out. Thanks.
