So yeah, my XL1 has a hot/dead pixel that is really annoying and can only be repaired for a chunk of change, like $900.

I know it's incredibly easy for obvious reasons to load up photoshop and correct an issue with stills, but I can't seem to find any information or ideas about how to correct the problem with video. Like, shouldn't there be a plugin around for grabbing the offending pixel and just filling it in with the color of the surrounding pixels? I naively assumed that somebody would have created an After Effects plug-in for that sort of thing, but if it exists then so far it has eluded me.

Thanks for any ideas/suggestions.

Is there a black balance feature on the XL1? I can't remember. Anyway, if there is, try black balancing it repeatedly until the dead pixel is gone. Other than that I'm not sure what you can do.

Cameras that are able to "repair" dead pixels are just hiding them with interpolation. One common cause of dead pixels is cosmic radiation, which is more intense at high altitudes and during solar storms.

These guys do a final cut pro plugin called re-incarnation - that seems to do exactly what you need. At £5.98 it won't break the bank.

There is a freebie plugin for VirtualDub if you are on PC. My first camera got a stuck pixel and this program disguised it. Its not a substitute, but it will do its best to hide it.

Thanks for all the input guys, I'm gonna try the $10 plugin from that UK site just 'cause it sounds like it'll do the trick and inexpensively.

FYI, I found this plugin from RevisionFX, which will probably work really well, but it's a bit on the spendy side.
