.credits and source frame rate

Hi, first of all thanks because AGK. I really thank you. I've got some question about ".credits" AGK help page tell "choose source frame rate", well I have some DVD with NTSC 29.97 fps, but after AGK encoded those I get a 23.97 avi file. So, how can I know what frame rate is going to have the final avi to calculate in which frame stars the credits? Because in the d2v file, in DGIndex, and VirtualDubMode is the same frame rate: "Frame_Rate=29970". I don't understand why when I open the *_preview.avs with virtualdub or mplayer2 the frame rate is 29.97, but if I open the *_movie.avs the frame rate is 23.97. The problem is that if I use 29.97 to calculate the credits file but the final avi is 23.97, I get a frame number (at which credits start) out of the movie. Sorry about my English. I hope you understand my problem.

Thanks len0x But i did use the source fps and i get this credits file (with 29.97): 169071 20 TRUE And the final movie had 142898 frames (with 23.97), so i think AGK never started to encode at 20% Am I right? Again thank you Len0x

just Thank you again Because all your work, Thanks
