What it does Lensfeed shows a camera's live preview inside After Effects.
No still frames but a moving live feed! Lensfeed is implemented as regular
After Effects filters so the livefeed is displayed inside compositions and
can can be treated like regular footage.

What it is good for This tool comes in handy to optimize shots for
compositions. Especially to adjust green- or bluescreen scenes to existing
footage. Using Lensfeed you can match perspective and lighting to achieve
beliefable setups. And since all the effects can be applied to the live
footage it's possible to optimize it for the keying tools used. This helps
creating higher quality footage and in reducing the work on the actual
composition later. How it works After Effects was not made with moving live
footage in mind. So implementing it was a bit tricky. Lensfeed consists of
effect plugins that render the current image from the camera to the
composition and a general After Effects plugin that makes it animate. This
second plugin unfortunately only works in After Effects. So in other hosts
there will only be single non animated frames. Possibly there will be
solutions for those in the future.
