Export a Still Frame from Final Cut.

This is how to export video from Final Cut Pro 6/7. Most software have a way to export a single frame, search the programs HELP menu for 'export' and 'still frame' or search online to find out specifically for your program.

Final Cut:
File > Export > Quicktime Conversion
Format: Still Image: Tiff, PNG, etc.

Open the exported image in Photoshop. If there is significant motion captured in the video still frame lines will appear. To remove the video motion use the following process in Photoshop.

Photoshop:
Filter > Video > De-interlace

Try various settings to see what looks best for that image. The de-interlace feature will remove the lines by duplicating the line above it, in turn the overall image has less crispness, but no motion lines created by the video capture process. Overall the filter is worth it for high motion still frames. Don't use the filter if there is no interlacing in the first place (camera is motionless; subject is motionless).

Resize the image to compensate for the rectangular pixels used by many cameras.

Photoshop:
Image > Image Size

Uncheck constrain proportions; adjust the width; choose appropriate bicubic scaling.

Conversion Sizes:

Layered photoshop images can be imported directly into many video programs. In the case of Final Cut Pro, the image size doesn't need to be changed as the layers proportions should remain intact.
