Re: Corner Pin not accurate in HD footage

Ok, I apologize for not getting to this sooner.

Your issue is the solid was not the same size as comp.
You footage and comp are all 1280x720, sq pixel.

The insert layer (your solid) is 300x400. This layer needs to be 1280x720 as well.

In your project I created a solid same as comp size and the track seems to line up fine.

There are lots of ways to deal with inserts that are not the same size such as scaling and pre-comping. Also, Red Giant's Warp gives the user dual source and target pins allowing you to deal with mismatched sources.
Hope this helps.
