Hello ssrini75 and wellcome :-)
so . . . it depends of which quality you wanna reach.
Consider that Amiga, for titling and logos in "superimpose" is still used nowadays.
If you want a standalone titler with the option of loading graphics for logos and so, you have 2 choises:
an Amiga with a genlock interface (there are with Composite-YC-YUV-RGB output) and a good program such Montage 24.
or an used broadcast embedded titler (usually with an internal floppy drive or even an HD)
What do you want achieve in terms of quality?
Bye
