Suresh, Sounds like you could use Ron Scott's Hi-Res QFX version 4, due shortly, where the batch processing has been restored. With that, you could change a range of blue (as in the background) to a single color, which you could then easily key out. My approach when I encountered a situation like this was to load some sample frames into TIPS (these were all .TGA images @ 512×486) & note the RGB values of the background. Then I wrote a 'C' utility to read the file & change the pixels that met the specified range. Used a DOS batch (FOR %%1 in (*.TGA), etc.) to rewrite the file to a different directory. Fortunately, I didn't have any blue eyes to account for, although you could test nearby pixels to determine if you were well inside an object (not contiguous with the background).
