Strange Offset Happening When Rendering

[user_deleted]

I have been doing a comp where an image replaces another on a hand held device.

I have tracked the corners into which the image is being placed, and then copied the track data into the cornerpin node coordinates.

The image looks ok when i use the playback buttons, but when i render the fileout node the replacement image appears to have moved a significant amount to the right, leaving a gaping black hole in the comp.

Any ideas what could be causing this shift? and how i can overcome it when i cannot see it in my Shake viewer screen?

thanks

What resolution are you working at and what res are you rendering at? Sometimes little errors don't show up if you are working at proxy resses?

How about using the stabilize node set to four point track, rather than linking to a cornerpin? Not sure it will make a difference but might be worth a try?

Are you using a photoshop file? If so, change it to a iff or some other file format.

actually yes! The image that is shifting was tinkered with in photoshop - although i don't remember the file type. I'll check that when i get back in work tomorrow.

I mean photoshop file as in .psd.

spot on, beaker.

It was a .psd, and as soon as i resaved it as a .tiff it worked perfectly.
Thanks very much.

I shall avoid .psd's in future.

It says in the manual that Shake doesn't support layers that don't fill the entire frame. So if you have an object in the upper left hand corner and only goes half way down, it will be moved to the lower left.

So you either have to fill the entire frame and use a mask or use an action script that writes all the layers to individual files.
