I'll assume you mean you want to do that programatically using (V)C++, otherwise you wouldn't be asking here. Imho take a look at writing directshow filters[^] for starters, i hope that will help.

I don't know what I and P frames are, sorry, i'm not much into video editing in details. To insert text i would write my own filter which takes the incoming frame, writes its text on it and then passes it along the graph (so it would have 1 input pin for incoming video frames and 1 output pin which passes the frame along after writing text onto it), i think video frames are (usually) passed as DIBs (Device Independent Bitmaps), so you should be able to use GDI (or GDI+) functions to write text onto these before letting them continue their journey. [edit] And of course, insert my filter into the filter graph by building the graph "manually". [/edit]

thanks for your thoughts .. this is I frames and Pframe FYI : http://en.wikipedia.org/wiki/Video_compression_picture_types[^]
**do u have any samples for insert text into frames ...?**:~ Failure is Success If we learn from it!!:~
