Riff files

Hi all;

I was wondering if anyone new a really good book detailed in RIFF files. I really need an advanced multimedia programming book. Thanks for any help.

Also i am trying to calculate the time of a movie. so i get the frame rate and i get the number of frames and times them together. then i divide that by 100 to put the time in seconds. The problem is 956 (frames) times (33) frame rate, gives 315 seconds, not 31.5. So how would i get an acurate time of the movie?

Give it a try here: http://www.wotsit.org/

They've got lots of file formats.
Hope this helps!
Have fun!

Isn't 33 in frames per sec? So to get an accurate time of the movie:

956 frames / 33 frames/second = 28.96 seconds
