Edge_checker

It's pretty simple to use.

You need to have an alpha in the footage to check the distorted edges.

Plugin the Input to the flow where edge distortion is needed to be checked. Click on Input range to apply the input range of the input to gizmo.

If the output color is Green, then shot edges are good to go.

If the output color is RED, then there must be an edge distortion on one or more than one frame.

To check the frame on which distortion exists, turn on the check_frame knob and play the sequence , the frame on which screen shows RED is the frame with error, the frame with Green is good to go.

Happy Comping!
