Thank you very much for the link.
I now manage to have the same image size when working in final cut.
I hope you do not mind me asking another question. I seem to lose a little bit of resolution. Could this be because i transfer an image worked onto photoshop to after effect and then back to final cut?
I have changed the file dimension before importing it into after effect (from 768x576 to 720x576) and i export the after effect file using quick time in the setting, thus reimporting a .mov file into final cut.
If you seem to lose resolution, check your placment and make sure you use "whole pixels". Both AE and Photoshop allow sub-pixel placment at fractional pixel values, which will cause the image to be resampled. The easiest way to ensure this in AE is to set the layer quality switch to "draft" so it turns off sub-pixel sampling.
Thank you ever so much for your time.
Still a little blurry but i need to fiddle with it a bit longer.
