spot on the camera

Is there any way to fix in post a spot of dust the was on the lense during filming? Its only visible when the characters black jacket passes by it a few times. Or do i need to reshoot?

how so? its a moving camera shot so i`m not sure the best way to try that without it being noticable, since the scene is constantly shifting behind it. Does AE have a clone tool like PS?

you'll need to motion track the blemish.... create a small mask to cover the blemish and track the motion, keeping the mask over the blemish as it moves... there are several tutorials there showing motion tracking... its just that the 01 tutorial does it well too...

go here and watch the 01 tutorial.... then try and apply it to your
footage...

You shouldn't have to track anthing if it is on the lense. Just duplicate the video layer in Premiere or AE. Shift the top layer a couple pixels, any direction. Then use the Mask or crop tool to crop the top layer just big enough to cover the spot, which will now be filled with image data from a couple pixels away.
If the spot is one pixel, you only have to shift one pixel, if it is two pixels, shift by two, etc. Avoid shifting vertically by an odd value, if you have interlaced footage, to avoid flicker. if most of the motion is side to side, grab the pixels above or below. If the primary motion is up and down, replace with pixels from one side or the other.
