Hi, i tracked a moving camera where you see a television turned off, then on top theres going to be a news show, with lower thirds.... the thing is taht the lower third looks very very bad after i apply the corner pinning.... is there any workaround for this BIG problem?
btw i tried after effects corner pin, redgiant warp and CC power pin, i get the same bad quality....

You might want to try using the align surface method:
Scale and comp the lower third in position, then precomp that layer.
In your mocha project (assuming the track is good) go to the frame that you positioned in AE, select layer and "align frame" to reset the surface to full frame.
Paste back to the pre-comped layer.
Hope this helps.

How does the graphic look if it is purely scaled down in AE without any corner pinning? It is possible the issue is related to the render/filter quality of the AE scaling in general and not the corner pin?
If you'd like to post the files for me to look at, I could do tomorrow.
As far as "align surface" this feature is commonly used if you wanted to paint or clone some the image and than apply tracking to that. You don't want to scale down your paint to the surface, you want the surface to remain full frame. Or in your case, you position the the logo (insert) within your comp rather than scaling down to the tracked surface.

ok i think i know what went wrong. The scale of the layer is set to 250% and then the corner pin effect scale down the stuff to fit it into position... now, how do i solve this?????? thanks

ok -
This is a known issue with mocha for AEv2 and the way corner pin and transform are split to different keyframes and only comes up on shots that have significant scaling or zoom.
The good news, is that we will post a point release next week that gives you the option to use the mocha for AE v1 style corner pin export that does not separate the keyframes and will do all the animation with-in corner pin.
So, the current work around is to launch the CS4 version 1 of mocha for AE and use older style corner pin export. The project will work in either version. If you do not own CS4, then shot me an email off the forum and I will send you a link to the new point pre-release.
Best,

I was having this same issue, and I've installed the new point release (2.1.0) but I'm not seeing any difference… both export options STILL scale the image over 200% instead of controlling it with corner pin info only.
I'm using AE CS3, does the fix you talk about not work for this version?

Thanks again Ross! I created an AppleScript to do the tedious find/replacing (with a bit of help from the guys on Apple's AppleScript forum).
I'm posting my script for anyone who has this same issue. Just save the Mocha corner pin info to your clipboard, then run this script and you're good to go:
---- START SCRIPT ----
try
-- places the text on the clipboard to a variable
set _text to (the clipboard) as text
set _headerFind to {"Adobe After Effects 6.0 Keyframe Data", "ADBE Corner Pin ", "ADBE Corner Pin-0003", "ADBE Corner Pin-0004", "ADBE Corner Pin-0001", "ADBE Corner Pin-0002"}
set _headerReplace to {"Adobe After Effects 8.0 Keyframe Data", "Corner Pin ", "Lower Left #4", "Lower Right #5", "Upper Left #2", "Upper Right #3"}
repeat with i from 1 to (count items of _headerFind)
--carries out the FIND and REPLACE
set AppleScript's text item delimiters to (item i of _headerFind)
set _newText to text items of _text
set AppleScript's text item delimiters to (item i of _headerReplace)
set _text to _newText as text
set AppleScript's text item delimiters to {""}
end repeat
-- puts the new text back on clipboard
set the clipboard to _text as text
